Description

Technical Field

[0001] The utility model relates to the field of wind power generation, and particularly to a hydraulic barring tooling. Background Art

[0002] With the rapid economic development and environmental protection, the demand for wind power generation has increased significantly. However, when a fault occurs in the blade of a wind turbine generator (or single-blade hoisting is required), the wind wheel needs to be rotated. In this scenario, the high-speed brake disc needs to be barring-rotated. However, in the prior art, due to limited strength, the manual barring method and the existing portable barring guns cannot achieve normal barring. At the same time, for the multi-drive barring tooling, the installation process is complex and the installation sequence is strict during installation. When in use, it is time-consuming and laborious. Considering factors such as too many installation components to be removed and limited space, it is difficult to control the barring speed, the operation time is long, and only one blade can be hoisted in a day, resulting in low barring work efficiency, difficult barring operation, and an unguaranteed barring working environment.
