Problems solved by technology
However, in practical applications, this lifting method has the following two disadvantages: one is that it is prone to safety accidents that injure the staff; the other is that the lifting height is not in place, which limits the comprehensiveness and meticulousness of the main grounding plate inspection. As a result, the inspectors cannot find the problems existing in the main grounding plate in time, which has buried potential safety hazards

The invention discloses a lifting inspection device for a main grounding polar plate in a pneumatic coal mine underground sump and an operation method of the lifting inspection device. The lifting inspection device comprises a lifting support, a pneumatic device box, a movable pulley and a first steel wire rope, and a first fixed pulley mounting seat is fixedly arranged on the lifting support; a first fixed pulley is mounted on the first fixed pulley mounting seat; a second fixed pulley mounting seat is fixedly arranged on the outer wall of the pneumatic device box; a second fixed pulley is mounted on the second fixed pulley mounting seat; a pneumatic hoist is arranged in the pneumatic device box; a rope winding disc is mounted on a main shaft of the pneumatic hoist; and one end of the first steel wire rope is fixedly arranged on the first fixed pulley mounting seat or the lifting support, and the other end of the first steel wire rope sequentially penetrates through the movable pulley, the first fixed pulley and the second fixed pulley and then is fixedly arranged on the rope winding disc. According to the lifting inspection device, the safety during inspection and maintenance of the main grounding pole plate can be ensured, and the labor intensity of inspectors can be greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of underground equipment in pneumatic coal mines, and in particular relates to a lifting inspection device for a main grounding plate in an underground water tank of a pneumatic coal mine and an operating method thereof. Background technique [0002] According to coal mine safety regulations, the main grounding plate should be buried in the water tank, and one piece should be installed for each of the main and auxiliary water tanks; among them, the main grounding plate should be a steel plate with an area of not less than 0.75 square meters and a thickness of not less than 5 mm. A piece of flat steel needs to be welded to connect the leads. The main grounding plate should be brought out for inspection every quarter. However, due to the heavy weight of the main grounding plate, it is difficult to lift, which brings great inconvenience to the daily inspection of the grounding plate. [0003] At present, whe...
