[0002] When mining, a lot of large equipment is often needed. However, under the high-intensity working conditions of mining, even large equipment will inevitably suffer from local deformation, damage, cracking, etc. For this reason, it is necessary to stop work in time to repair the equipment. However, the current maintenance method is mostly manual disassembly and repair by workers.

[0003] Due to the large size and bulkiness of the equipment, in the absence of professional maintenance equipment, workers use traditional tools such as pipe pliers, wrenches, sockets, and sledgehammers to disassemble and assemble them by hammering and knocking.

Therefore, there is an urgent need for a device that can assist workers in disassembling such large mining equipment parts to help workers complete the work.

[0004] Since mining equipment is used in mines for a long time, a lot of dust will adhere to the surface of the shaft. When disassembling and assembling the axle of the mining equipment, the bearing needs to be removed from the shaft.
