Claims

The device for moving the downhole equipment consists of a beam 1 with hydraulic legs 2 and 3 mounted hingedly at both ends of the beam, a carriage 4 which has the ability to move along the beam 1 along rails 5, a plow unit 6 mounted on a slide 7, hydraulic jacks 8 with supports 9 and 10, of the rotary frame 11, on which the bypass blocks 12 and 13 are installed, interacting with flexible traction bodies 14 and 15, which are connected with one end to the lugs of the pneumatic rod 16 and the other to the sliders 17 that slide guides 18 and connected with the hydraulic ram 19 and 20 rods, oriented by longitudinal axes along the drift, which are attached to the brackets 21 located on the rails 18 and at the same time fixing the latter in the rotary frame And, hydraulic jacks 22 advancing, pneumatic cylinders 23 fixed on the bases of the pallets 24 located at both ends of the device in the windows 25 of the beam 1 and having stops 26. I The operation of the device is as follows. In the initial position, the device is mounted on the drift in a position that enables the carriage 4 to move along the beam 1 following the movement of the lining, and the structure to remove the strip of coal. The hydraulics 2, 3, and 8, as well as the hydraulics of the plow unit 6, are under pressure, as a result of which the device is in the open state. After stripping the coal strip along the entire length of the lava, the thrust is removed from the hydraulic legs of the plow 6 and the hydraulic screw 8 of the carriage 4. Simultaneously, the pressure is supplied to the hydraulic jacks 22 advancing the hydraulic jacks 19. The force from the hydraulic jacks 19 is transmitted through a flexible pull The harness 14 on the traction rods 16 supports, which moves a predetermined pitch. Simultaneously with the lining along the beam 1, but the guide 5 moves the carriage 4, on which the plow installation 6 and the pivoting frame 11 are mounted. Then, pressure is applied to the hydraulic jacks 8 and the hydraulic post of the plow installation 6, the carriage 4 is spread in the drift, after which the coal strip is removed and repetition The operation of shifting the lining with the only difference is that the work involves traction hydraulic jacks 20 and flexible traction, organ 15. The step of shifting the supports is multiple to the stroke of the hydraulic jack 22 advancing, therefore, after the stroke I of the hydraulic jack 22 shifting. it will be chosen to the end, the beam 1 is shifted, along the track, following the advance of the lava by a distance equal to the motion of the shift jack 22. The operation of shifting the beam 1 is carried out after the strut is removed from the hydraulic posts 8 and the hydraulic legs of the plow 6, the compressed air under pressure will fill the pneumatic cylinders 23, which will lift the carriage 4 to a height limited by the stops 26 located on the pallet 24 and the carriage 4. Thereafter the pill 6 and the hydraulic rigging 2 and 3 are hydraulically supported and the carriage 4 is fixed relative to the roadway. With the girders 2 and 3, the thrust is removed, the beam 1 loses contact with the side walls of the drift and, after pressure is supplied to the hydraulic cavity of the shifter 22 of the slide, moves over the soil of the drift following the carriage 4 to the initial position. The beam 1 has two windows 25, through which the pallet 24 can be moved by the stroke of the shifter jacks 22. Zan to its original position, the device is distributed in the drift by hydraulic posts 2 and 3, compressed air is blown out of the air bellows 23, the carriage 4 is lowered onto the guides 5 and moves. Such an embodiment of the downhole equipment mobile device allows reducing the cycle time of the lining and plow movement without the presence of people in the clearing face. Apparatus of the Invention A device for moving a downhole equipment including a beam with hydraulic legs, a carriage with hydraulic legs and guides for a plow installation, installed with a possibility of movement along the beam by means of shifting hydraulic jacks and connected with sliders of hydraulic pushing jacks, characterized in that, in order to shorten the time the movement cycle when moving the pneumatic support with traction rods, the carriage is equipped with a swing frame with bypass blocks having flexible traction bodies l communication with m govymi schtangami bellows support frame, wherein the one ends of the traction flexible bodies are fixed on slides, and by pulling hydraulic cylinders disposed along the beam.
