Abstract

The invention provides a blade replacement tool. The blade replacement tool comprises a clamping device and a hoisting and releasing device, wherein the clamping device comprises a bearing part, a first rotating plate and a second rotating plate hinged to the two opposite edges of the bearing part separately, and a rotating plate drive piece for driving the first rotating plate and the second rotating plate to pivot relative to the bearing part; and the hoisting and releasing device comprises a cross beam and a rope connected between the bearing part and the cross beam through a winch mechanism; and the middle of the bearing part arch towards the cross beam relative to the two edges of the bearing part. With the blade replacement tool, shorter blade replacement time, higher replacement efficiency and lower cost can be achieved, and the safety and reliability can be improved.

Description

technical field [0001] The present invention relates to the technical field of wind power equipment maintenance, and more specifically, relates to a blade replacement tool for replacing complete blades or broken blades. Background technique [0002] As the unit capacity of wind turbines increases gradually, the difficulty of replacing large components of wind turbines also increases. The replacement of blades in the maintenance of large components of wind turbines is the most difficult, especially for blades that are in a broken state. Replacement poses great difficulties. At present, for offshore wind turbines with broken blades, there is no mature spreader in China to replace the broken blades. In addition, only for a single complete blade, the complete machine manufacturer will develop a corresponding single-blade spreader for the installation and removal of a single blade, and the blade is only limited to the state where the blade is complete without breaking, and Only...
