[0002] The shaft group used in the mine mainly includes the crushing shaft group (that is, the pulley shaft group) and the sprocket shaft group. It is the key component of the crusher and the power actuator for raw coal crushing. The shaft group is used in the harsh working conditions of coal mines for a long time, causing the wear of the sprocket body or the pulley body and the crushing hammer head, and the internal heating and locking of the bearings, which need to be replaced regularly. Due to the large shape and weight of the shaft group, and the deformation of the transition between the cutter seat and the crushing shaft due to long-term use, it is difficult to disassemble. In the past, people would use manual hammering, using a sledgehammer to frequently hit the parts to break them, and also use flame gas cutting to destroy some parts to protect the high-value parts, which is very labor-intensive. However, no matter which method is used, it will cause damage to other parts and increase the maintenance cost.

[0003] In order to reduce the difficulty of disassembly and reduce maintenance costs, a disassembly device specifically for shaft groups has been developed on the market. However, the device can only fix and support a specific shaft group. When the overall structure of the shaft group changes, the device cannot be used. The crushing shaft group and the sprocket shaft group have different diameters, different external structures, and different fixing methods. The above disassembly device can only disassemble one of the shaft groups, the crushing shaft group or the sprocket shaft group, and cannot disassemble shaft groups of different specifications.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content
