Description

Technical Field

[0001] This application relates to the field of wind turbine technology, and more specifically, to a tool for facilitating the turning of a wind turbine. Background Technology

[0002] The content in this section provides only background information related to this application and may not constitute prior art.

[0003] During long-term operation of the wind turbine, the turbine hub needs to be inspected. During inspection, the locking pin needs to be inserted into the hole of the impeller brake disc to fix the impeller brake disc and lock the hub, making it easier for operators to inspect the hub. When there is no wind, the impeller brake disc does not rotate, and the locking pin cannot be inserted into the corresponding hole of the impeller brake disc.

[0004] The wind turbine maintenance manual requires that the wind turbine locking pin be tightened before entering the hub. However, it is difficult for the manufacturer to accurately stop the main shaft hole at the locking pin and extend the pin without interference in the initial design. At present, the method is for workers to manually rotate the high-speed shaft brake disc to transmit the signal to the main shaft wind turbine through the gearbox. Due to the wind direction force and its own weight, the wind turbine is sometimes very heavy and difficult to control. There is an urgent need for a practical tool to help production.

[0005] The purpose of this invention is to provide a wrench-clamping turning tool that is safe, labor-saving, efficient, and improves productivity, thus solving the problems in the existing technology. A tool similar to a clamp or wrench, 1.2 meters in length, is made. The worker holds the handle end and clamps the clamp end to the brake disc. By applying force with both hands and using the fulcrum to press downwards, the clamp head moves upwards. This leverage principle greatly saves effort and is highly efficient. Utility Model Content
