Description

"

The invention relates to construction and installation works, in particular, to devices for the installation of vertical structures.

The purpose of the invention is to improve the ease of installation in cramped conditions and reduce its labor intensity.

Figure 1 shows a device for mounting vertical structures in one of the first to start the installation position; FIG. 2 - the same, after lifting the upper block and docking with it of the parts of the block following it; on fig.Z - dismantling the device in part from installed on the support structure; FIG. 4 is a section A-A in FIG. 2; FIG. 5 is a view B of FIG. 4; Fig.6 section bb In Fig, 4,

The device contains a support stand, to which in its upper part a support-centering unit is fixed on the flanges 2, completed in the form of three e) AMOK 3, having two ends at the ends or more large rollers 4. The frames 3 are located radially from the support post at an angle of 120 ° to each other and held in this position by means of 5, which are fastened to the frames with detachable connections (for example, bolts), fixed blocks 6 of the polyspasts, mobile blocks 7 are attached to the upper part of the support stand 1. which are attached to the bottom of the raised structure,

The device works as follows.

Inside the upper part of the mountable block 8 of the structure being in a horizontal position.

secured with a traction unit 9 and using a cable 0, the device is assembled and fitted due to the rotation of the rollers 4 through the inner

5 to the diameter of the structure, inside the block, to the upper part of the block 8, holding retainers II are fixed, a top block 8 with the device inside is placed in a vertical position on the supports 12 by a Crane (not shown), and two parts are pulled up block 13, following the upper block 8 of the structure, and start lifting, pulling the cable 14

5 tackles, the movable blocks of which are fixed, for example, to mounting fittings 15 of the structure. When lifting the shrouds, 11 are released, keeping the system in a vertical position,

0 After lifting the block 8 to the height of the brackets 16 fixed to the block: 13, the hooks 17 fixed to the block 8, engage with the clip I6 and further lift the block 8 and parts

5 of the block {3 is carried out simultaneously: assembling the choke of block 13, after which the next lift is made,

J Then, the raised part of the structure is installed on the supports 19, using the cable 10. The device is dismantled in parts and the installation of the structures is completed by feeding and joining the lower unit 20,
