Abstract

The invention provides a hoisting device which comprises a main beam, at least two connecting parts connected to the main beam and at least two clamps connected to the lower portions of the corresponding connecting parts in the two connecting parts, and the position of each clamp relatively to the main beam is adjustable. By means of the hoisting device in the concept, the problem that a broken blade is difficult to replace can be solved, the blade replacement time is shortened, the replacement frequency is increased, and the replacement cost is reduced.

Description

technical field [0001] The invention relates to a hoisting device for a wind power generating set. Background technique [0002] The blades of wind turbines tend to be larger. The lengthening of the blades can increase the power generation of wind turbines, but with that, it becomes more difficult to replace the blades. [0003] At present, there have been some mature experience in the replacement of the whole blade of the wind power generating set. Replacement of broken blades is difficult, so maintenance personnel spend a long time looking for a solution to replace the broken blades. [0004] figure 1 A view schematically showing a situation where a blade of a wind turbine is broken off. For prior art disassembly figure 1 The method for the broken blade 1 (including the blade part 1-1 and the blade part 1-2) of the wind power generating set 100 in the wind power generating set 100 includes the following steps: first, the maintenance personnel determines the broken pos...
