Description
Technical Field
The utility model relates to a lifting tool, in particular to a horizontal hydraulic generator stator and rotor integral lifting tool, and belongs to the technical field of lifting tool design and manufacture.
Background
At present, no matter the horizontal hydroelectric generating set is installed or overhauled, the rotor and the rotating shaft are required to penetrate or withdraw from the whole stator. The penetration and extraction of the rotor requires a considerable length of space at the front end of the unit, otherwise the rotor cannot be completely penetrated and extracted from the stator. For the condition that the length space of the front end of the unit is insufficient, the operation can be performed only after the stator is lifted by using the jack and the cushion block. And under the condition that the front end of the unit does not have any redundant space, the stator and the rotor can only be integrally hoisted into and out of the machine pit. Because the method for integrally lifting the stator and the rotor is generally adopted, the rotor magnetic pole part is directly placed on the stator core to lift the stator, not only the lifting safety is not ensured, but also the whole rotor weight is applied on the stator core to easily cause the deformation of the stator core or damage of the slot wedge and the coil, thereby causing irreparable loss. There is therefore a need for improvements in the art.
