Technical Field

The utility model relates to the technical field of eccentric sleeve disassembly tools, in particular to an electric hooking mechanism for disassembling an eccentric sleeve of a turnout.

Background Art

The eccentric sleeve is a necessary component for high-speed railway turnouts. Due to the changes in the track gauge and direction of the high-speed railway line, as well as the aging and wear of the eccentric sleeve itself, the eccentric sleeve needs to be frequently disassembled and replaced to meet the requirements of high line smoothness; however, since the eccentric sleeve is installed very firmly, especially after long-term use, the eccentric sleeve of the turnout is often adhered to the turnout base plate due to long-term weathering, sun exposure, rain and train loads, and is easily adhered to the concrete structure, making it very difficult to remove. At present, when disassembling and replacing, tools such as hooks, crowbars, and chisels are basically used to violently remove them by knocking, prying, etc., which is very difficult to operate and easily damages the surrounding concrete structure. It usually requires the cooperation of multiple people and takes a long time to remove, which is inefficient.
