DESCRIPTION OF THE INVENTION

The invention relates to the installation of vertical structures, primarily mobile wind power plants, and to elements of vertically mounted structures and can be used for accelerated installation of structures for various purposes, including for rapid response systems, for example in emergency situations, in response to accidents and disasters .

A mobile wind power plant of low power is known in which the support is made in the form of separate air-filled elastic toroidal sections, the cavities of which are communicating with one another via a flexible hose (see AS No. 164854, 01.01.62, class F 03 D 11/00 ).

This well-known technical solution requires special equipment: assembly of compressor, pneumatic fittings, pipelines, which reduces the mobility of the installation and the scope of its application, complicates the technology of work. In addition, such a support design predetermines its large cross-section, which creates large wind loads. In addition, the support of the air-elastic elements does not have sufficient lateral rigidity, especially in the presence of significant lateral forces, resulting in the development of self-oscillating processes during wind gusts, which limits the use of this known technical solution for the construction of vertical structures for various purposes: antennas, cable masts, Wind power plants, etc.

Known is the method of mounting a vertical structure in the form of a power line support, see as. USSR No. 1035175 of August 3, 1981, the class. E 04 H 12/00, where the installation of the structure made of a single pillar and support, and the foundation and foundation is carried out on a pre-prepared foundation through a compensator with an elastic element, connect the upper end of the column with the pullers provided with tensioning devices, anchor in the soil anchors And connect the lower ends of the guys.

In comparison with traditional methods, the method in question allows to increase the operational reliability of structures when using them in power transmission lines and to reduce the costs of their repair and post-emergency recovery associated with failure due to deformations in the base of the structure.

The method of installation in question is characterized by the following drawbacks.

Installation is not possible without the following construction and installation works:

  • On erection (oboznolichivaniyu) foundation;
  • On the translation of the column from the transport position of the horizontal to the working position, vertical;
  • On the penetration of anchors into the ground, etc. And their sealing and fixing.

In addition, transport and lifting equipment is required, and in the case of weighting the mast and increasing its height, the method requires additional means, including a crane.

Installation is not possible or is not reliable enough when supporting the stand directly on the ground, ice, gravel, o barge, etc. those. Without foundation preparation.

The installation provides a single rack, therefore it has practically limited application, mainly in height and weight.

The presence of these operations, conditions and means indicates that the height of the mast is fixed, its increase will lead to greater restrictions for land transportation, increased installation costs and inability or limited use.

The presence of a large number of construction and installation operations, including the erection of the foundation and the deepening of the anchoring of the anchors, leads to an increase in the cost of installation.

A method for mounting vertical structures is known (see AS No. 1219767 of 04/07/84, class E 04 H 12/00), in which the installation of the structure made from the component sections and the base is carried out on a paved area to which individual Section and base. With the help of lifting equipment, slings and flexible rods, each section is successively raised to a height sufficient to bring the following section to its lower end, to attach it and raise the interconnected sections to the height of one section.

After the design connection of the upper and the undergrowth of the lower sections, the lower level braces are transferred to be fastened to the lower part of the upper section and the dredging for the next lift.

In the initial stage of installation or even before it, the ground under the work platform and under the base is profiled, leveled, compacted and grounded with a base.

On the work platform and base prepared in this way after being released during the installation process to the nominal height, the part of the vertical structure thus assembled by the crane assembled in this way is lifted and moved and elevated above the hardened base, leading to a nominal position in which the assembled part is fixed relative to the hardened base Or even before it.

According to the function performed and the result achieved, this method of installation is the closest to the claimed and selected as a prototype.

Such a known method in relation to the known to date dramatically reduces the installation time of the vertical structure.

However, he has the following drawbacks.

Installation begins with construction and erection works for the erection of a foundation, paved areas both for the metalwork of the winch itself and for the possibility of arriving and maneuvering vehicles, transport platforms, cranes and parts of metal structures mounted on these sites.

Installation can be carried out only if there are a number of transport, lifting and crane facilities that perform only their transport or lifting functions.

Installation is not possible or ineffective in field or unprepared conditions, for example directly on the ground, asphalt, gravel, rock bottom, ice, barge, etc.

Therefore, such a method, due to the presence of these operations and means, requires definitely greater material resources and the time required to carry out these operations, i.e. Such a method is characterized by high cost and installation costs of considerable time.

In the same known technical solution for carrying out the mounting method according to a.c. No. 1219767 of 04/07/84, Cl. E 04 H 12/00), a device is considered a sectional module, which is a three-dimensional power structure of the truss type, the upper and lower base, the inter-module attachment points and the stitching units.

The disadvantages of this device is that the relatively simple design of the module used to mount the vertical structure complicates the mounting technology. The module does not contain any elements that allow fixing its horizontal displacements during installation, and accordingly the entire already mounted part. Installation is carried out with careful compliance with the tension and movement of the cables on which the module is hung, which limits the installation conditions for the time of day, wind conditions, requires the involvement of highly qualified personnel and a large number of equipment, as well as a large amount of preparatory work for the installation of installation sites.

Mounted structure before its measurement on the foundation is statically and dynamically unstable, which greatly complicates the installation and increases the installation time, increases the risk.

The object of the invention is:

  • Provision of installation without construction and installation operations to build a foundation, reducing the cost of installation, reducing the number of required personnel;
  • Simplification of installation technology, reduction of terms and expansion of weather and climatic conditions of installation;
  • Ensuring the installation of structures in the conditions of liquidation of accidents and disasters.

The aim is achieved due to the fact that, according to the invention, the sections and basic structures are transported to the installation site, a series of lifting and docking of each section is carried out at the installation site, while the hollow base of the structure is disconnected from the construction platform, an inner support contour On the ground, basing on the base of the supporting contour, form under the base aperture greater dimensions of the transport platform, then remove the transport platform and form an external supporting contour to the ground, close the outer support contour with the upper section of the lifted structure by flexible connections and keep in the process of lifting the structure and at the end Lifting their tension.

An additional difference of the claimed method is that the formation of the inner and outer support circuits leads from the condition of perception by the inner support contour that mainly the load is due to the weight of the structure, and the external lateral, mainly wind loads.

The mast of the vertical structure is subjected to a compressive load during lifting, which is mainly due to the tension of the flexible bars, which constantly or monotonously changes as the lift increases, the main compressive load being closed to the outer support circuit with the formation of the maximum counter-torque.

The erected structure is additionally equipped with means for locating and fixing functional objects on the mast section, for example pipes, cables, pipes of wires, lighting devices. In the case where a number of bases of mounted structures are installed on the transport platform after installation of the first structure, the platform is removed to the installation site of the next vertical structure and provides a mechanical, optical, electrical, radio, tele- or other connection to the previous structure.

Transportation and installation of the already assembled structure can be carried out by applying efforts to lift to the top of the structure, tearing its base off the ground and moving it to a new installation site where the base of the structure is again supported on the ground.

The device by means of which the claimed method of mounting vertical structures composed of sections of a sectional module is implemented, comprises a frame with two upper and lower bases, nodes of intermodule attachment on the bases, and is equipped with guides fixed to the frame for interaction with a load-lifting device, Volumetric power structure, and the nodes of modular fastening on the bases are located in pairs on each and diagonally opposite to the rotation of the diagonals on the respective bases by an angle relative to each other.

Additional differences of the device are the execution of the core of the module in the form of a truss structure, a section of a round or oval section pipe, a box-like structure, but also that it can be equipped with nodes for fixing flexible connections on it, as well as functional equipment. The intermodule attachment points on each of the bases can be made in the form of at least two grippers and corresponding holes for the grippers, and in the form of at least two pins and return holes.

The attached drawings show: FIG. 1 sectional module, Fig. 2 - sectional module, type A, see Fig. 1, Fig. 3 sectional module, type B, see Fig. 1, Fig. 4, 5 variants of intermodule attachment assemblies, Fig. 6 embodiments of guides for horizontal locking and lifting of the section module, FIG. 7 mounted from the mast modules of the wind power plant, FIG. 8 installation of a cable line on a sectional mast using the claimed method and apparatus; FIG. 9, the base of the vertical structure mounted on the transport platform in a condition prepared for transport, FIG. 10 the scheme of the load action from the weight of the vertical structure (for example, the wind power plant), from the wind flow and the perception of the load by the external and internal support circuits.

The drawings and materials of the application indicate: 1 module core, 2 top base, 3 bottom base, 4, 5 intermodule attachment points (4 cone pin option, 5 pin hole), 6 guides, 7 gear wheel of a lifting device installed on The base of the structure, 8, 9 of the diagonal, in which the nodes 4, 5 of the intermodule attachment are pairwise disposed, 10 the mast of the vertical structure (VEU), 11 - the base (power cage) of the structure, 12 the transport platform, 13 - the ground, 14 supports (adjustable) Contour, 15 peripheral trusses of the external support contour, 16 peripheral supports (adjustable) of the external support contour, 17 upper section of the lifting structure (mast), 18 - flexible connections, 19 load-lifting device, 20 prefabricated farms, 21 - levers on the power cage.

The sectional module (Figures 1-5) comprises a frame 1 with two bases - upper 2 and lower 3, nodes 4, 5 of intermodule fastening made on bases 2 and 3, guides 6 made, for example, in the form of rails, angles, profiles T-section, toothed racks with holes for the forging wheel (see Figure 6) and fixed to the frame for interaction with the load-lifting device 7, the frame 1 is made in the form of a bulky power structure, and the modules of the inter-module fixation 4, 5 on the bases 2 and 3 Are arranged in pairs on each and diagonally opposite to the rotation of the diagonals 8, 9 on the respective bases 2 and 3 by an angle with respect to each other (in Figure 1, a variant with an angle of 90 degrees is shown).

The skeleton 1 can be made in the form of a shaped structure, for example welded from the cross-sectional profiles (shown in Figure 1) or rectangular or circular pipes, and is in the form of a pipe section of a round or oval section of a shell or box-like structure, for example of sheet metal or Stamped or curved sheets or plates. The module can be equipped with nodes for fixing flexible connections on it to create tension of structures, as well as nodes for fixing a functional hazard on it.

The nodes of the inter-module fixation 4, 5 on the module bases can be made in various ways.

For example, as shown in FIG. 1, in the form of a pair of conical pins and holes: a conical pin 4, FIG. 3, 4 of one module enters the hole of the next module when it is docked. In this way, the modules are fixed to each other in the transverse direction.

The nodes of the intermodule fastening can be made in the form of a simple bolted connection, for which the holes of the module are made on the base of the module (see Figure 3).

Various kinds of quick-action clamping devices can be used in the form of, for example, spring grippers, as shown in FIG. 5 on one module and the corresponding profiled pin on the other module.

It should be emphasized that the claimed modules are most effectively used in the structure of structures that are strained during installation and after assembly by compressive forces. Therefore, the nodes of the intermodule attachment should limit the predominantly transverse displacement of the modules relative to each other and effectively perceive the compressive forces.

The hoisting means 19 used to extend the mast of the vertical structure can be performed in various ways, for example in the form of a gear wheel coupled to a rack, or a fork wheel with a rail, a friction pair "roller guide". The construction of the lifting device is not considered in this application, for more details, see the application "Mobile wind power installation and installation method for a mobile wind power plant" sent to VNIIGPE by the same applicant. N 4 / 1-95 of 30.01.95.

Let's consider the declared method of installation of the vertical designs made of sections on an example of installation of a mobile wind power installation which in the assembled state is shown on fig. 7, and in which the mast 10 is made of sectional modules (or sections).

The vertical structure is mounted as follows

Transported to the installation site of the section 1 and the base 11 of the structure, directly on site, the base of the structure, hollow with the central hole, is disconnected from the transport platform 12, supporting the base 11 on the ground 13, forming an inner supporting contour on the ground and forming an archway under the base 11 , Large dimensions of the transport platform 12, after which the transport platform 12 is removed and an external support circuit is formed.

The movable transport platform 12 is removed from under the arched opening formed by the power cage 11, the trimmings 20 and the levers 21 with the adjustable supports 14 supported against the ground 14. The mast 10 is loosened from the upper section module 17 relative to the power cage 11. Then the top module of the mast 17 Has the ability to move forwardly relative to the guides 6 on the load-lifting device 19 fixed to the power cage 11. The same sectional mast modules are made in height definitely less than the height H of the aperture formed by the power cage 11 of the coarse truss 20 and the levers 21.

An outer support loop is formed by connecting to the base 11 at the locations of the inner frame supports 14 of the peripheral trusses 15 and the peripheral supports 16.

After that, the outer support circuit is closed with the upper section 17 of the lifted structure by flexible ties 18 and the tension of the flexible bonds is maintained during the lifting of the structure.

When assembling, the formation of the internal support contour is carried out from the condition that it primarily perceives the loads from the weight of the structure (and the weight of the equipment and / or rigging fixed on the upper section of the mast), and the formation of an external support loop results from predominantly lateral wind loads, for example, for wind power.

The installation of a vertical structure is carried out under the condition that a constant axial compressive load is created and maintained constant or monotonously varying in magnitude during the ascent, i. E. The mast of the vertical construction is driven under a compressive load. The axial compressive load can be created in various ways. For example, due to the weight of the equipment fixed on the top section 17 of the mast, and due to the tension of the mast by the compressive force. In the claimed method, the axial compressive force is created by tensioning the flexible bonds 18.

In this case, the axial compressive load is closed to the outer support circuit using peripheral supports 16 which are provided with nodes for securing flexible links 18. For the tensioning of the rods 18 and changing their length during the lifting of the structure, devices are used in the form of special mechanisms. As the simplest mechanism for tensioning, for example, a lanyard can be used, which, when screwed, changes the length of the thrust. In order to regulate the length and tension of the flexible links when the mast extends, a more complex mechanism of the known ones can be used, for example, the mechanism of a manual rescue fire extinguishing device, which provides pulling the cable for a length of up to 30-50 meters with a resistance force of up to 125 and more "kgf" ± 50 degrees Celsius, a brochure describing this rescue mechanism is attached ["Fire Rescue Device Individual., USPI 4-50, USSR Ministry of Internal Affairs, Institute of Fire Defense, M. 1991]

When pulling the cable at a certain adjustable speed (from 0 to 3 m / s), the device creates a tension force of up to 125 kgf. The pulling force of the cable is inherently inelastic dissipative and is created by the organization of a viscous resistance of the liquid in the device (other embodiments of this device are possible for much greater efforts up to hundreds of "kgf" ​​and up to tons.) This solution is independent, Consideration of it is not given).

In combination with the lanyards, such and other known tensioning devices, including spring elements in the claimed method, effectively solve the problem of creating an axial compressive force both during the extension of the structure and at the end of the extension.

Spreading of flexible links to peripheral supports The closure of forces on the external support circuit makes it possible to create a rigid power triangle that effectively perceives lateral acting loads applied at the height to the upper module of the mast, creates the maximum counter-torque and allows to unload the mast of the structure from bending loads.

To expand the functionality, the mounted structure is additionally equipped with means for locating and fixing objects in the form of pipes, cables, pipelines, lighting devices in the functional equipment sections. These funds can be placed on both the upper and the intermediate modules of the tower.

When forming linear objects, such as cable routes, fiber-optic lines created in conditions, for example, emergency situations, in the liquidation of accidents, disasters, etc. On unprepared sites, with a lack of qualified personnel and under the influence of opposing factors, in the claimed method, a number of bases of assembled structures are installed on the transport platform, and after the installation of the first structure the platform is removed to the installation site of the next vertical structure, and thus erecting a series of vertical structures , Provide mechanical, optical, electrical, radio, television and other communications.

Mounted according to the claimed method, the vertical construction consisting of sectional modules has high rigidity due to the presence of intermodule attachment points, axial compressive load, and creation of closed power triangles from the upper module (section) of the mast to the peripheral supports of the external support contour, which provides not only Effective perception of the existing loads from the functional equipment or working equipment fixed to the upper mast module, but also makes it possible to transfer the entire assembled structure to a new installation site without dismantling operations.

The transfer can be carried out using a crane over the top module of the mast, using a helicopter, i. E. Transportation and installation of the structure is carried out by applying force to rise to the top of the structure, while tearing off the main structures from the ground and moving it assembled to a new installation site where the base of the structure is again supported directly on the ground.

During transport (in the basic variant of the method), the base of the structure is in the folded state on the transport platform, as shown in FIG. 9. Sectional modules, peripheral forms are transported separately, for example in a trailer or other car.

The formation of two support loops allows us to distinguish between the tasks assigned to the support circuits with the position of perceiving the loads from the weight and loads when the structure is operating in operating conditions.

As a result, the peripheral trusses 15 are unloaded from the static load by the weight of the structure and are loaded only with the dynamic component from the wind wheel (for the wind turbine) or from the equipment installed on the upper mast module and its external links, cables, etc. But also by the tension force of the flexible rods 18. The peripheral trusses 15 only perceive a part of the load-compressing structure of the loads, since the peripheral supports 16, when executed in the form of liquid or bulk containers, have considerable weight, for example, for a 10 kW wind turbine, Of the peripheral supports is 1.0 1.8 tf, which completely offloads the peripheral supports 15 from bending loads. This makes it possible to make peripheral farms easy and transportable, which reduces the complexity and cost of installation operations, reduces the need for personnel in preparatory operations and during installation.

Consider the scheme of loads applied to the vertical structure using the example of a mobile wind turbine.

When the wind flow is affected, the resistance force Q (see Figure 10) tends to overturn the wind turbine. The developed external support circuit does not allow to overturn the wind turbine.

As can be seen from the circuit of FIG. 10, the weight of the wind turbine and the weight of the peripheral supports (in particular when filling their tanks with a loose or liquid medium) resist the tipping.

The equilibrium condition for the non-dropping of the wind turbine is approximately written in the form



Where H is the height of the axis of the wind wheel;

Q force of aerodynamic resistance of windwheel to wind flow during operation of wind turbine;

K safety factor, taking into account the gustiness of the wind and other random factors;

(K @ 1.3 ... 1.5)

N GВн reaction from the weight of the i-th support of the external contour;

R Внi is the projection of the radius of installation of the i-th support of the external reference contour to the direction of the wind flow;

N number of supports of the external reference contour;

G veu weight of the wind turbine;

R is the distance from the vertical axis of the wind turbine to the nearest external support in the projection to the direction of the wind flow.

As can be seen from equation (1), the weight of the outer peripheral support applied on the larger arm than the weight of the wind turbine creates a large counter-torque. Therefore, the desire to reduce the weight of wind turbines due to the organization of two support circuits

Internal, perceiving mainly the load of the weight of the assembled structure with functional equipment, and the external one from the condition of perceiving mainly functional loads, in particular lateral loads, for example loads from the wind turbine of the wind turbine, is justified and expedient. This makes it possible to achieve a reduction in material intensity, cost and to ensure the convenience of transporting the structure and does not contradict the task of ensuring the stability of the assembled structure under various disturbances, including wind disturbances.

For example, for H 15.0 m, n 4, R inside 3.0 m Q 1.0 t, R v 6.0 m G ve, 1.0 tc, the effective torque MQ H 15 ton is balanced as follows:

Due to the weight of the windmill with the direction of the wind flow at an angle of 45 degrees between the supports,

M Gveu 3.0 m h cos 45 oh 1.0 tf 2.1 tm

That when using classical solutions requires anchoring of flexible bonds in the ground on a significant base for perception of the external acting moment M 15 tm;

Due to the weight of the outer (peripheral) supports

MG BH 12.0 m h cos45 oh 2.0 tf 17.0 tm

Thus, the efficiency of using an external support circuit with supports in the form of containers for liquid or bulk filler is evident.

As shown by the design development, the most effective is the application of the claimed method and device for fast-mounted mobile (redeployed) wind power plants, antenna devices, cable masts, etc. For the needs of the Ministry of Defense, the Ministry of Emergencies, and civilian sectors: agriculture, farmers, expeditions, etc.

The time of deployment of the installation of a vertical structure according to the claimed method of a mobile windmill with a capacity of 10 kW for 1 hour with the operation of two installation operators. The weight of one sectional module does not exceed 20 kg, which completely eliminates the need for crane equipment for installation.

The claimed method and device are progressive, and their practical use creates a positive effect, which is as follows:

  • Shortening of the terms of installation of structures;
  • Reduction in cost, weight, material consumption of vertically mounted structures due to the complete exclusion of the vehicle from the structure of the structure;
  • Reducing the cost of structures;
  • Increase of universality due to the possibility of installing structures on sufficiently loose soils without their preliminary preparation and use of modules;
  • Providing the possibility of making different objects for different purposes, for example, lighting devices, cables, hydrants, antennas, wind turbines of the windmills, especially for variants of re-routed windmills, oriented to work in low-speed wind flows at the required height.
