Description

; 54) STRING INSTALLATION

The invention relates to coal cleaning means, namely, devices for a plow notch with controllable power bodies.

Known planer installation, in which in the structures of the ring-type carriage bearing cutters are equipped with upper and lower telescopes 1.

The disadvantage of these devices is that they provide reservoir capacity control within insignificant limits.

Closest to the proposed technical essence and the achieved result is a plow installation, which includes an executive body in the form of carriages mounted on the upper and lower rails, a mechanized lining containing bottom and bottom posts, bases and floors, placed between the bottom holes and bottom posts, conveyor and hydraulic jacks control G2.

However, the range of reservoir capacity control in this unit is limited to two extreme positions of control hydraulic jacks.

The purpose of the invention is to increase the range of adjustment of the executive body in terms of reservoir power, as well as the accuracy and reliability of controlling this process.

This goal is achieved by the fact that the executive body of the proposed plow installation is designed as an autonomous device consisting of upper and lower guides, equipped with plow carriages, the drive for which is mounted on the same guides. Moreover, both directions are connected by means of 15 bushings mounted on bottom-hole racks, and the control hydraulic jacks are hingedly connected to bushings and support brackets. With the help of control hydraulic jacks, the actuator can be moved across the entire reservoir thickness.

FIG. 1 shows the device, a general view of FIG. 2 is a section A-L in FIG. 1} in FIG. 3 - section BB

25 in FIG. one.

The device includes an executive Body, mechanized lining and downhole conveyor.

The executive body includes

30 upper 1 and lower 2 guides, on which the upper 3 and lower 4 plow carriages are connected with a traction chain, drive b, tensioning device 7 and adjusting sleeves 8, with which the upper lower guide are interconnected. Through these bushings, the actuator is mounted movably on the bottom racks of the lining. The actuator is displaced by the reservoir power using hydraulic jacks 9 of the control. Each bottom carriage 4 is equipped with a loading plowshare 10, which are hinged on them hinged to ensure that during their work the movement of coal in the direction from the drifts to the linear sections of the bottomhole conveyor, having a minimum loading height, is achieved. installation without cutting preparatory niches. The mechanized lining consists of separate sections, which include bottom-hole racks 11, ground stanchions 12, bases 13, shchkrekry 14 with retractable visors 15, supported by bottom-hole racks 11, fences 16 and jacks 17 of the support shafts. To prevent dust from entering the air flow and to provide separate ventilation of the bottomhole spaces, the lining sections are equipped with telescopic curtains 18, and the bottomhole conveyor is equipped with a casing 19. The drive is controlled by hydraulic motors powered by pumping stations installed in the gates, or adjustable electric drives . The Strugov plant operates as follows. The cycle begins with a notch of the executive body, which at this moment must be in one of its extreme positions (on the ground or on the roof). The actuator is driven before the notch. The notch is made by d: id jacks 17, feeding the downhole conveyor to the sides of the factory, along with bottom holes 11, on which the actuator is mounted, and retractable, canopies 15 resting on these stands. The feed rate must match:; be the depth of the chips to be removed. When the actuator actuator is engaged, the chain moves the plow carriages along the bottom by a step size between the carriages, after which the drive is reversed. At the same time, the hydraulic jacks 9 are activated, with the help of which the actuator moves along the formation thickness. When the upper cutters of the plow carriages reach the line of contact of the coal mass with the roof (or soil), the executive body is re-supplied to the bottom, and the hydraulic jacks 9 are reversed and the cycle is repeated. Chip removal in the course of work is carried out both with forward and reverse plow carriages. The coal is loaded onto the downhole conveyor by means of plowshares 10 and the loading end of the conveyor. The adjustment of the executive body according to the hypsometry of the formation is carried out by adjusting the course of the hydraulic jacks 9 of the control. In accordance with this direction, the beams of the executive body are made of separate sections that are hinged to each other. The shifting of the support sections is performed in a staggered order after the pillars and the actuator are moved by the amount of the main pitch of the lining (0.40, 8 m). The invention of the Strugov installation, including an actuator in the form of carriages mounted on the upper and lower directions to the chi, mechanized lining containing bottom-hole and zavalnye racks, bases and floors, located between the bottom-hole and zavalnye racks, conveyor and hydraulic control jacks that, in order to increase the range, accuracy and reliability of reservoir power control, the carriage drive is mounted on the guides of the actuator, which are interconnected by means of tulok mounted on a bottomhole stoykahj control hydraulic cylinders are pivotally connected to hubs and bolting overlap mi.
