Problems solved by technology

However, the above two hoisting methods must have a main hoist with sufficient tonnage and necessary auxiliary hoist (the auxiliary hoist of the rabbit ear hoisting method also needs to change with the quality of the wind rotor and the height of the tower), with the development of wind turbine technology , the height of the tower is getting higher and highe

Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0057] The core of the present invention is to provide a wind wheel hoisting tool, the wind wheel hoisting tool can realize the hoisting of the wind wheel and the removal of the wind wheel without a crane, thereby saving the hoisting cost of replacing large parts, and at the same time, the tool can realize the 90° of the wind wheel in the air It can be turned over at a certain degree, and the inclination angle of the nacelle of different types of units can be a...

Abstract

The invention discloses a wind wheel hoisting tool. The wind wheel hoisting tool comprises a main hoisting beam with a plurality of slide wheel assemblies, a drive mechanism which is arranged on the main hoisting beam, and a supporting beam assembly, wherein a hanger assembly which is used for hoisting a wind wheel to realize mounting or dismounting the wind wheel is wound on any slide wheel assembly; the drive mechanism is connected to all hanger assemblies, and can provide drive force; and the supporting beam assembly is used for fixedly connecting a main hoisting beam to a fan main shaft positioned below the main hoisting beam to realize supporting the main hoisting beam, and can transmit gravity of the wind wheel to the fan main shaft. The wind wheel hoisting tool is fixedly mounted onthe fan main shaft, so that the wind wheel can be hoisted and dismounted without a hoist, and therefore, hoisting cost for large part replacement can be saved; and meanwhile, the tool can realize 90-degree turnover, in air, of the wind wheel, and also cancels a tailing crane.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind wheel hoisting tool. Background technique [0002] At present, during the entire life of the wind turbine, due to the replacement of large parts such as blades, hubs, main shafts, and gearboxes after damage or replacement due to technical upgrades, the wind turbine rotor needs to be hoisted. The hoisting methods of the wind turbine rotor mainly include two hoisting methods: rabbit ear hoisting and single blade hoisting. Among them, rabbit ear hoisting refers to the installation of two slings at the root of the two blades adjacent to the tower, and the other two slings. The end is hung on the hook of the crane, and the third blade is used as the tail blade. A sling is installed in the design stress area of ​​the tail blade and hung on the hook of the auxiliary crane, so that the main crane can be used to lift the wind wheel. The auxiliary crane pulls the thir...
