Description

Technical Field

[0001] This utility model belongs to the field of turning gear tooling technology, and specifically relates to a simple turning gear tooling for wind turbine units. Background Technology

[0002] Alignment is a critical and regularly performed task in the maintenance and operation of wind turbines. Typically, wind turbines require alignment once a year to ensure normal operation and optimal performance.

[0003] Currently, during the alignment process, three alignment points need to be set. These points are determined by the rotation of the fan, and the alignment data of the fan is then verified based on these points. However, in actual operation, some problems have troubled the operators. Sometimes the fan unit does not rotate in the set direction, or the rotation speed is too fast, making it impossible to select the alignment point at the predetermined position. This has brought inconvenience and difficulty to the alignment operation.

[0004] To address these issues, electric turning trolleys are currently commonly used for operation. However, electric turning trolley fixtures also have some drawbacks. First, their large size makes transportation extremely inconvenient, increasing operational complexity and cost. Furthermore, some wind turbines, due to design limitations, lack the necessary mounting holes for electric turning trolley fixtures, rendering them unusable. Moreover, the high cost of electric turning trolley fixtures undoubtedly increases wind turbine maintenance costs, limiting their widespread application.

[0005] In summary, the existing turning gear used for wind turbine alignment has many problems, and a more efficient and convenient turning gear device is needed to achieve wind turbine alignment, reduce maintenance costs, and ensure the stable operation of wind turbines. Utility Model Content
