(54) DEVICE FOR MAINTAINING MINING IN THE AREA OF INFLUENCE OF CLEARING WORKS

one

The invention relates to the mining industry, in particular, to devices that are intended to maintain the mine workings adjacent to the clearing of the bottom during the purposeless excavation of coal.

The mating support is known, inclusive, and the frames containing hydraulically supported longitudinal beams, one of which includes guiding skis, with the longitudinal beams interconnected by movement and jack jacks of the adjustment 1.

The disadvantage of this construction is that due to the limited length of the beams, it is impossible to mount the preparatory development outside the interface in the zone of active influence of the cleaning works.

The closest technical solution is a device for maintaining mine workings in the zone of influence of cleaning works, including hydraulic racks, installed under the support lining frames 2.

The disadvantage of this design is the great laboriousness of rearranging hydroelectric rails, since this process is not mechanized.

The purpose of the invention is to increase the labor productivity of the landlord by reducing the laboriousness of the work during the rearrangement of the posts. The goal is achieved by the fact that the device is equipped with a monorail having a ring shape, a bracket with a roller and a notch, and a lock installed in the indicated notch, the bracket being mounted movably relative to the upper part of the hydrorack, and a roller with the ability to interact with the monorail by the fact that the annular mono-rail has a length of at least three times the distance of installation of hydroelectric rails.

FIG. 1 shows a general view of the device in plan; in fig. 2 - view A of FIG. I; in fig. 3 - section bb FIG. 2; in fig. 4 - preparation of the hydraulic post for movement along. monorail; on fnl. 5 - the movement of the annular monorail and hydraulic lines.

Claims (2)

The device for supporting workings consists of hydraulic rails 1, installed under the support lining frames and interconnected by an annular monorail 2 by means of a bracket 3. Each bracket 3 is mounted movably relative to the sliding part of the hydrorack 2 and has a notch 4 for a latch 5 and a roller 6 with 7 more contacting the bracket 3 with the annular monorail 2 during the movement of the hydrorack I. The fixer 5 serves to secure the hydrorack 1 on the monorail 2 during and after its movement. The minimum length of the annular monorail 2 is selected on the basis of three times the distance of installation of the hydraulic rails 1, which corresponds to the condition of keeping the monorail 2 in the initial position, and the maximum length of the monorail 2 is determined by the size of the active zone in the cleaning operation. In the initial position, hydraulics 1 are unstretched, and the monorail 2 supports fixed brackets 3 hydro-racks 1. Following the movement of the cleaning face and movable mate by the magnitude of the cycle, monorail 2, which passes freely through the notch 4 of the bracket 3, is moved fix in front of the installed and uncoupled hydraulic rails 1. After shifting the monorail 2 on the last hydrorack 1 (from the worked-out area), the wedge retainer 5 of the bracket 3 is knocked out and the strut is removed from it. When this happens, the sliding part of the stem part of the stem 8 squeezes into the bracket 3 and the cylinder is tightened over the ground to provide the gaps required for free transportation along the monorail 2 of the hydraulic post 1, which in this position is supported by the roller b on the monorail 2. After this In preparation, the hydraulics i is moved along the monorail 2 to the new installation site (Fig. 5) and spreads it into the arch of the next frame. At the end of the thrust, in order to further maintain the rail 2, the arm 3 is secured with a latch 5. The relocation of the monorail and the movement of the subsequent hydraulic legs is carried out in a similar order after the next cycle of coal excavation and relocation of the support mating. The use of the invention will allow to increase the productivity of the keeper due to the mechanization of the process of moving the girders and reducing the time for their installation, as well as ensure the reliable maintenance of generation in the area of active roof shifts. Claim 1. A device for maintaining mine workings in the zone of influence of sewage works, including hydraulic racks installed under the support lining frames, is characterized in that it is equipped with a monorail to increase the labor productivity of the builder by reducing the labor intensity of shifting the hydraulic racks. ring shape, roller bracket and notch and retainer, installed; the bracket is mounted for movement relative to the upper part of the hydraulic post, and the roller is capable of interacting with the monorail. 2. A device according to claim 1, characterized in that the annular monorail has a length of at least three times the distance of the installation of hydroelectric supports.
