Description

one

The invention can be used in the mining industry and is intended for mounting the roof in the areas of interface of lava with drifts during mining of mechanized deposits. _five

Known mechanized lining mates, consisting of a base, Uppermen, gidroetek, hydraulic jacks and protective elements [1].

The use of retractable sideboards on the end sections of the supports was not effective because of the insufficient amount of sliding and reliability of the retractable sides.

The closest solution to the proposed technical essence and the achieved result is a mechanized lining of the mates, including the base, hydraulic legs connected to the base and the Uppermen with the possibility of deviating them in the transverse direction, hydraulic jacks and flexible connections established between the Upperboxes [2].

The disadvantage of this device is the lack of adaptability to the changing size of the overlap pro2

the space between the main and drip lining and lack of reliability of fastening.

The aim of the invention is to improve the adaptability to the changing size of the non-overlapped space between the main and drift lining and increase the reliability of fastening.

This goal is achieved by the fact that the lining is equipped with rigidly mounted on the side of the laval lining additional hydraulically upper and Uppermouth with flexible connections for connection with the adjacent Upperstream, and hydrojacks attached to the extreme width of the section hydraulics.

body-supporting types; FIG 7 is a section B-B of FIG. 6

Mechanized lining mates can be structurally executed in two versions: for taller mechanized lining of the supporting type and for laval mechanized lining of the protective and protective-supporting types.

In the first embodiment, the mechanized lining of the mates consists of the base 1, on which the front hydrorails 2, 3, 4 and the rear hydrorails 5, 6 and 7 are installed. The hydroracks 2 and 5 are fixed rigidly on the base I, and the hydroracks 3, 4, 6 and 7 can rotate across the base 1 at a predetermined angle by means of hydraulic jacks 8 and 9. Each pair of front and rear hydraulic rails is pivotally connected with the Upper 10, 11, 12, which are interconnected by flexible ties 13. With loose roofs over flexible ties to the Upper Moors 10, 11, 12 can be fixed kapron and and rubber tape (not shown). The mutually overlapping guard flaps 14 are attached to the Upper houses 10, П, 12.

According to the second embodiment, the mechanized lining of mates consists of a base ί, on which hydraulic racks 2, 3, 4 and brackets 15, 16, 17 are installed. Hydraulic ram 2 and bracket 15 are fixed rigidly on the base 1, and hydrorack 3, 4 and brackets 16 and 17 can be rotated on horizontal hinges across the base 1 at a predetermined angle by means of hydraulic jacks 8 and 9. The upper part of the hydraulic rails and brackets is connected by horizontal hinges with the upper bars 10, 11 and 1.2, which are interconnected by a flexible link 13. The upper bars 10, 11 and 12 are mutually attached overlapping guard plates.

The base 1 is connected by means of hydraulic jacks movement with the left conveyor (base) or is attached pivotally to the base of the extreme section 18 of the main body support.

Mechanized lining mating is installed between the extreme section 18 of the lava mechanized lining and the extreme section 19 of the drift mechanized lining. The mechanized prep mates after shifting the drift and laval mechanized roof supports moves.

.Mechanized mating lining for the lower part of the lava and the lower drift is a structure similar to that described above, but rotated 180 ° in the plane of the face, i.e., in this case, the upper structure will be a common element for all hydraulic posts.

Mechanized lining mates works as follows.

Before shifting, the mating supports for new hydraulics 2, 3, 4, 5, 6 and 7 are reduced by the required amount and the upper 10, -11 and 12 are unloaded from the pressure of the roof rocks, after which the hydraulic jacks 8 and 9 are placed in the position to drain and movement mechanized lining mates.

The shifting of the mating lining is possible in one of two ways: by pulling the base 1 to the face support conveyor of the lava support by means of the built-in hydraulic jack of movement (not shown in the drawings); in conjunction with the lava section of the mechanized support, for which the base 1 of the mechanized support should be connected by horizontal hinges with the base of the lava section of the support.

During the movement of the mechanized lining of the mating, its Uppermen with hydrorests are shifted or moved apart fanlike in the transverse direction by means of hydraulic jacks 8 and 9 depending on the width of the gap between the extreme lateral 18 and the drift 19 sections of the mechanized supports. In this case, the protective flaps 14, suspended from the Upper 10, 11 and 12, also fan out, protecting the space from the side of the dam. Flexible links 13 provide for the sequential movement of the upper frame 11 of the middle frame following the movement of the upper frame 10 of the leftmost frame. In addition, flexible connections 13 prevent the falling of pieces of rock from the roof through the gaps between Verkhnyak 10, 11 and 12. To prevent spilling of loose roof rocks into the gaps between Verkhnyak 10. 11 and 12 can be fixed on the upper roof (above flexible ties 13) nylon or rubberized shields (not shown in the drawings).

After shifting the mechanized lining of the mates, each pair of front and rear hydraulic racks is spread in the following sequence: first hydraulic rails 2 and 5 are torn, then hydraulic rails 3 and 6, and last are hydraulic rails 4 and 7, i.e. alternate preload is applied to the roof of the upright 12, 11 and 10.

On this cycle of work with mechanized lining mating ends.
