Wind generating set barring assembly and barring method

Abstract

The invention provides a wind generating set barring assembly which at least comprises a support beam, a first hydraulic cylinder, a first connection base and a second connection base. The support beam is provided with a connection portion used for being connected with a non-rotating part of a wind generator and a connection portion used for being fixedly connected with the first connection base. The first connection base is used for connecting one end of the first hydraulic cylinder to the support beam, and the second connection base is used for connecting the other end of the hydraulic cylinder to a rotor of the wind generator. The assembly is at least provided with a first state and a second state. The support beam, the first hydraulic cylinder, the first connection base and the second connection base are arranged in a separation mode under the first state. Under the second state, one end of the first hydraulic cylinder is connected onto the support beam through the first connection base, and the other end of the first hydraulic cylinder is connected onto the second connection base. A barring method is further provided. The assembly is simple in structure, low in cost, capable of being used repeatedly and good in economy.

Description

technical field [0001] The present application relates to a wind power generating set barring assembly and a barring method. Background technique [0002] During the hoisting and operation and maintenance of wind turbines, for example, when installation and maintenance personnel need to enter the hub of the wind rotor for operation, the generator needs to be feathered and shut down and then locked with a locking pin to prevent accidents such as casualties caused by the rotation of the wind rotor Occurrence, that is, need to turn the car. Direct-drive wind turbines cannot be cranked by rotating the high-speed shaft because they do not have a gearbox, so it is difficult to crank the direct-drive wind turbine. [0003] In the existing turning technology of wind turbines, because the blades of high-power wind turbines are very heavy, manual operation is very difficult. The method of using a large crane to hook a blade and slowly lift it to rotate the wind wheel is very expensiv...
