Description

General overhead hoist of wind generating set wheel hub Technical Field The utility model relates to the technical field of wind generating set hub lifting, in particular to a universal lifting device for a wind generating set hub. Background The main stream wheel hub overhead hoist in the market at present adopts split hanging seat structure more, matches through a plurality of independent hanging seats and wheel hub top screw, uses high strength bolt to carry out rigidity fixedly. However, this design has problems of non-versatility, low operating efficiency, potential safety hazard, high management cost, and the like. The wheel hubs of different types are obviously different in size, screw hole layout and bearing requirements, so that hanging seats are required to be customized one by one and cannot be reused across the types, single lifting operation takes more than 40 minutes, the turnover efficiency of a production line is affected, personnel working aloft is at risk of falling, the components can be possibly caused to fall due to misoperation of a pneumatic wrench, and the wheel hubs provided by multiple suppliers are matched with different hanging seats, so that the storage management difficulty is increased. Therefore, an innovative structural design is needed to realize the universalization of the cross-machine type of the lifting device so as to solve the limitation of the prior art. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides a general lifting device for a hub of a wind generating set, which can effectively solve the problems of poor universality, low operation efficiency, multiple potential safety hazards, high management cost and the like of the conventional lifting device for the hub.
