Currently, there are mainly the following two ways for the removal of track rust end couplings. 1. And (5) a mechanical disassembly mode. The mode mainly adopts a mechanical reinforcement mode, and realizes larger output torque through a reinforcement mechanism so as to achieve the purpose of disassembly. The method can realize the disassembly of the common rust parts, and is simple and easy to operate. However, for severely rusted parts, the disassembly cannot be performed due to the small torque output by the parts. Meanwhile, the labor intensity of operators is high, and the efficiency is low. 2.
