Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a base of a unit lifting mechanism. Background Art

[0002] The base of the unit lifting mechanism refers to the base structure used to support and fix the unit lifting mechanism. The unit lifting mechanism is usually used in energy facilities such as hydropower stations and thermal power plants to lift or lower the generator set for maintenance, inspection or troubleshooting.

[0003] The base and the unit lifting mechanism are generally connected together through a lifting guide rod, which serves as a limit guide for starting the lifting mechanism. The lifting guide rod is fixedly connected to the top of the base, and its fixed connection is usually through bolts or welding.

[0004] However, welding is not convenient for disassembly and assembly between the base and the guide rod, making assembly time-consuming and laborious. Bolt connection is convenient for disassembly between the base and the guide rod, but when the guide rod is subjected to force by the lifting mechanism, the guide rod is easy to rotate relative to the bolt, causing the guide rod to separate from the bolt, making the guide rod unable to be stably connected to the base, and easily causing the guide rod to separate from the base, resulting in poor safety.
