Description

Technical Field

[0001] The invention relates to the field of a wind tower surface groove repairing device, and in particular to a mobile tooling for processing surface depressions of a large-diameter wind tower. Background Art

[0002] The wind turbine tower is the tower of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit. It is an important component. The concave defect causes a significant decrease in the supporting force of the tower, which will cause the risk of tower collapse during the service life of the wind tower. For this reason, the DIN18800-4:1990-11 standard stipulates the tower concave deviation. The tower that exceeds the standard deviation must be rounded. In recent years, with the development of offshore wind power, large-diameter towers have appeared one after another. The traditional rounding tooling has become longer and longer, which brings great difficulty to workers during operation. For large-diameter towers, the tooling is difficult to use during the rounding process. For example, the 5.5m diameter offshore wind power tower currently under production has a rounding tooling length of 5m. The tooling is quite laborious in the erection process. Each time a concave part is corrected, it needs to be erected once, and it is easy to fall again during use, causing great safety hazards. Summary of the invention
