The design is made in the form of a nolucole and an anchor of one of the lengths, placed inside the cylindrical guides with the possibility of changing the position.

FIG. 1 shows mechanized heel; in fig. 2 - section A-A of FIG. one.

The support consists of linear sections, each of which includes a non-opening 1, hydraulic legs 2, base 3, base beam 4, consisting of separate sliding widths and wide sections within the linear sections, and base sections 5.

The base section of the base sections between them is articulated and forms two spaced apart across ca 7 and 8. Linear and base sections are connected by the upper 9 and lower 10 jacks of movement. Located with a scoop of CTOpoiHj, backfill the stowing pipe with 11 ho. Mutes 12 krenits to onorny.h; telescopic flocks 13, which in turn are fastened with the help of fillers 14 on supporting frames 15.

On, 1; 1, the supporting frames 15 are inserted into the apertures of the rear part of the base sections and fixed in them by pieces of 16.

Each 15 pulley-bearing box carries screamed and semi-rings 17. The semi-columns, ca, are oioro for support sites 18, a row of which forms a pathway for people to travel along the grain pipe. The location of the support pads on the half-rings allows for infinite adjustment of their position when the angle of the support position changes. Regarding the half-rings 17, the support pads 18 are fixed with the help of bolts 19, which tighten the bent portion 20 of the support pad and the lath 21 located on the outer side of the half-ring. After removing the tape, the carbon base beam, with the linear sections uncoupled, simultaneously moves along the entire front of the jacks and the movement to the new track. The backfill pipe, fastened to the base beam through the supporting frames, without loss of straightness, moves with it. Then alternately with the section, the thrust is sieved and they are pulled to the bottom. The presence of a track located near

Claims (2)

for the passage of people, it makes it possible to considerably simplify and speed up the processes associated with servicing the pipeline and carrying out the installation works. Claims of the invention: Mechanized roof support, including linear sections, base beam and backfill wire Tpy6oj, located on the filling side, fixed on the supporting frameworks connected to the base beam, in order to improve the serviceability of the backfill pipe when the support angle changes, it is equipped with cylindrical guides in the form of half-rings and supporting platforms placed inside the cylindrical guides with the possibility of changing the position.
