Abstract

The invention provides a blade hoisting auxiliary structure for a wind driven generator,a system and a hoisting method. The blade hoisting auxiliary structure comprises a first beam and a second beam,wherein the first end of the first beam can be detachably connected to a connecting flange of a hub; and the second beam is fixed to the second end, opposite to the first end, of the first beam, a first included angle is formed between the first beam and the second beam, and the first included angle can be greater than or equal to 90 degrees and smaller than 180 degrees. The blade hoisting auxiliary structure can perform horizontal hoisting even when the connecting flange is at a non-horizontal position, and the auxiliary structure can be matched with the corresponding connecting flange, so that the blade mounting efficiency is improved, and labor force is reduced.

Description

technical field

[0001] The invention belongs to the technical field of wind power generation equipment, and in particular relates to a blade hoisting auxiliary structure for a wind power generator, a blade hoisting auxiliary system and a blade hoisting method. Background technique

[0002] Wind turbines (referred to as fans) are devices that convert wind energy into electrical energy, using wind power to drive the blades to rotate, and then drive the generator to rotate to generate electricity. With the continuous increase of fan power, the volume of the fan blades will also become larger and longer, and the self-weight and moment of inertia of the entire impeller will also increase, so the installation of super long and super large blades will become more and more difficult. Bigger and more expensive.

[0003] At present, in the process of installing and disassembling the fan blades, or when the generator is stuck, it is usually necessary to crank the generator. Barring i...
