The invention provides a lifting appliance for lifting an impeller and a lifting method for the impeller. The lifting appliance comprises a flange butt-joint plate, a main body part, a lifting connector and a lifting ring, wherein a connecting hole corresponding to a threaded hole of an impeller hub is formed in the flange butt-joint plate; the main body part extends upwards from the flange butt-joint plate by a preset length; the lifting connector is formed at the end, opposite to the flange butt-joint plate, of the main body part and used for being connected with a lifting belt during lifting of the impeller; and the lifting ring is arranged at the outer side of the main body part. According to the lifting appliance for lifting the impeller in the embodiment of the invention, the structure is small, manufacturing is simple, and production cost is lowered. As a lifting lug structure does not need to be designed at a manhole of the impeller hub, the structure of the hub is simplified, the weight of the hub is reduced, and the manufacturing difficulty of the hub is lowered.
Description
technical field [0001] The invention relates to a sling for hoisting an impeller and a hoisting method for the impeller, in particular to a sling for hoisting an impeller of a wind power generator and a method for hoisting the impeller using the sling. Background technique [0002] Direct-drive wind turbines are mainly composed of blades, impellers, generators, and nacelles. At present, the hoisting of direct-drive wind turbines mostly adopts split hoisting, that is, the blades, impellers, generators, and nacelle are transported to the hoisting site of the direct-drive wind turbines separately. The hoisting sequence of the direct-drive wind turbine is generally as follows: (1) hoisting the nacelle, connecting the nacelle to the tower; (2) hoisting the generator, connecting the generator to the nacelle; (3) assembling the blade-impeller, The three blades are respectively connected to the flange of the impeller; (4) the two blades are hoisted with two slings to lift the blade...
