[0002] Underground work in a coal mine refers to a series of mining, tunneling, ventilation, electromechanical, transportation and other operations carried out in the underground part of a coal mine. High-pressure pumps play a vital role in underground work in a coal mine. When a mine encounters water damage or a sudden water inrush, the high-pressure pump can quickly start and discharge a large amount of accumulated water, effectively preventing the expansion of water damage and ensuring the safe production of the mine. At the same time, the high-pressure water flow provided by the high-pressure pump can fractur e and depressurize the hard and thick roof overlying the coal seam, thereby improving mining conditions and increasing mining efficiency.

[0048] Implementation process: when it is necessary to remove the sealing cover 11 from the surface of the crankcase 1, the rotation knob 42 drives the worm 41 to rotate synchronously, and the rotation of the worm 41 drives the worm wheel 4 and the rotating shaft 1 31 to rotate, thereby driving the bevel gear 2 36 to rotate synchronously, and the rotation of the bevel gear 2 36 drives the bevel gear 1 35 and the rotating shaft 2 34 to rotate, thereby driving the gear 1 37 and the gear 2 38 meshing with the gear 1 37 to rotate, and the rotation of the gear 2 38 drives the bidirectional threaded rod 22 to rotate synchronously. At the same time, the rotation of the bidirectional threaded rod 22 drives the blocks 23 on both sides to move toward each other, so that the two blocks 23 are disengaged from the inside of the slot 24, and then the sealing cover 11 is pulled forward to remove the sealing cover 11 from the surface of the crankcase 1. At the same time, due to the setting of the sealing strip 51, the sealing between the crankcase 1 and the sealing cover 11 is greatly improved to prevent foreign matter from invading the interior of the crankcase 1. When it is necessary to install the sealing cover 11, the reverse operation is sufficient.
