Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generator set equipment maintenance, in particular to a device for facilitating the maintenance and disassembly of a yaw caliper of a wind turbine generator set. Background Art

[0002] When a wind turbine is put into operation, the yaw system will frequently calibrate the wind direction, and the yaw caliper will often be used to ensure that the wind turbine is in a stable static state at the end of operation, thereby enhancing the unit's ability to resist loads. The yaw caliper is a hydraulic device. When stationary, the yaw caliper will firmly lock the cabin to keep the unit stationary. When the wind turbine yaws against the wind, the brake still maintains a certain pressure to make the yaw movement more stable and avoid possible shaking.

[0003] Due to the long-term operation of the yaw caliper, the connection between the yaw caliper and the wind turbine will have different degrees of sealing ring damage, brake pad wear, and oil leakage, which seriously affect the safe and stable operation of the wind turbine. For safety reasons, the yaw caliper with sealing ring damage, brake pad wear, and oil leakage needs to be repaired or replaced as a whole. However, since the wind turbine is large and high, a large manpower cost is required for disassembly and maintenance. In addition, the yaw calipers of wind turbines of different sizes have different installation heights, which makes operation inconvenient. Utility Model Content
