Description

The invention relates to the construction and can be used for the installation of long vertical structures by sectional growing of the lower part,

The aim of the invention is to improve the performance and expansion of technological capabilities.

Figure 1 shows a diagram of the device for mounting three-sided lengthy vertical structures, top view; Fig. 2 shows a section A-A in Fig. 1, the initial stage of the installation of the structure; fig.Z - the same, the final stage of installation of the structure; FIG. 4 is a diagram of a device for mounting lengthy vertical structures in an axonometric view; FIG. Fig.5 is a diagram of the device for mounting four-sided lengthy vertical structures, top view; on fig.b - the scheme of the storage of four cargo polyspasts and cascading ends of lolispastnyh cables.

A device for mounting a lengthy vertical structure 1 by growing its lower part with pre-enlarged sections 2 includes a lifting structure that carries adjustable braces of the lower part of the raised structure 1, made in the form of equal multiplicity of cargo polyspasts 4 to its axis 3, and equipped with a lifting winch 5, s which by means of a cable 6 connects in parallel the 4 cables 8 brought out through the diverting blocks 7 descending ends of the cables stored in the cargo tackles 8. The device includes kzhe tensioning safety device, provided with a winch 9, a system of moving and stationary block 10 and the yokes 11 and pass therethrough equalizing rope

12, one end of which is connected to the counterweight 13, and the other wound on the drum of the winch 9, and adjustable braces 14 of the upper rus, which are unequally inclined to the vertical axis 3 of the raised structure 1. On the structure 1 are located the rigging elements 15, installed in horizontal levels on the lower part each section 2 for securing the lower block

clips 16 cargo polyspasts 4, on the upper part of the structure 1 or in the places of installation of the design braces for fastening the upper ends of the adjustable braces 14 of the upper Rus. Lifting elements 15

are located in radial clearing planes intersecting along the central axis 3 of the raised structure 1, and equidistant from this axis at the corresponding levels. The core 17 with concentric circumferences in horizontal levels are located with branch blocks 18, through which the lower ends of adjustable braces 14 are stored, which are parallelly connected to the corresponding.

movable block clips 10 of the safety tensioner. When mounting tower-type structures, it is sufficient to use only one upper Russian braces.

The lifting structure is made in the form of 3 booms 19 equally tilted to the axis 3, fixed by means of jib tackles 20 of the same multiplicity and axial hinges 21 in planes

scrapping the bottom of the lifted structure 1. The upper block clips 22 of the cargo tackle blocks 4 are attached to the ends of the mounting booms 19 4. Axial hinges 21. in which the bases of the mounting booms 19 are fixed, oriented

perpendicular to the corresponding planes of milling and equidistant from the central axis 3 of the lifted structure 1 The casually ends of the 20 cables 23 put into the boom polyspasts 20 are drawn through the tap-off blocks 24 and connected in parallel to the rope 25 wound on the drum of the additional winch 26.

In addition, in a lifting structure carrying more than three adjustable braces in the form of cargo hoists 4, running down the ends of cables 8 stored in them, with the exception of two hoists 4 that are not located in the same plane, are attached to the winch rope 5 of the hoist winch 5 by means of an additional / A cable trunking system 27 mounted on a cross beam 28 attached to the end of the cable 6

Prior to the installation of a lengthy vertical structure, at the design development stage of the assembly work, additional technical requirements for mounting the 1 rigging elements 15 on the structure are made. To do this, mark the radial plane of the upper and lower parts of the structure 1 to be scaled. 120 ° to each other of the radial planes. The bracing of the bottom clock and the structures of a triangular or steep cross section, also the purpose of j, is carried out in the direction of the glom 120 ° to each other. The lower part of the vertical structures, made in the form of multifaceted (more than three faces) lattice frameworks, should be marshled along the directions of the radial planes passing through the center of the design vertical axis of the structure and carrying the frame along the framework. Levels equidistant in each of them from the central axis 3 of the construction 1 At the same time, the lifting elements 15 (slinging points) on the lower part of each section 2 have For example, on top of the frame bearing carriers, as well as rigging elements for securing the upper arm braces can be mounted either on the armor or on the outboard brackets 29 attached to the frame diaphragm structures. When mounting tower type structures, only one upper armored braces are used, and assembling structures of the type of multi-rascally cradled masts, the upper ends of the braces of the upper Rus are attached to the rigging elements of the design
