Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices, in particular to a turning device for processing wind turbine blades. Background Art

[0002] With the rapid increase in my country's wind power installed capacity, large-scale wind farms have been built in areas with rich wind resources. At the same time, the wind resource characteristics of the area have also changed to a certain extent, causing the output power of wind turbines matched with the original wind resource characteristics to decrease. Wind turbines mainly rely on wind turbine blades to capture wind energy. The length of wind turbine blades directly affects the ability of wind turbines to capture wind energy and the output power of wind turbine generator sets. Wind energy is a clean and pollution-free renewable energy that has been used by people for a long time. my country's wind turbine blade industry is undergoing an industry-wide reshuffle and integration. As the market scale of wind turbine blades expands, both costs and selling prices will decline, but companies with scale, technology and cost advantages will reduce costs faster than selling prices, and their profits will exceed the average level.

[0003] The existing announcement number is CN 216229265 U. A turning device for processing wind turbine blades belongs to the technical field of wind turbine blade auxiliary devices. The flange is driven to rotate by the rotation of the motor, and then the wind turbine blade on the flange is driven to rotate. At the same time, the clamping device in the supporting turning device clamps the tail of the wind turbine blade. Under the action of force, the inner ring of the bearing is driven to rotate to realize the 360-degree turning of the entire wind turbine blade processing turning device, which solves the problem that the processing of wind turbine blades at different positions can only be turned by lifting machinery. However, there are still certain shortcomings in this patent. The overall device of this patent is a fixed structure. When processing the wind turbine blades, the whole needs to be processed 360 degrees, which makes it impossible for the staff to adjust the relative height of the wind turbine blades according to the actual work process. At the same time, the patent is provided with a track, and the overall area is large. At the same time, a large crane is still required to place the wind turbine blades on the device bearings. When it is necessary to turn over the blades that exceed the track, the fixed length of the track further limits the turning work. Therefore, we propose a turning device for processing wind turbine blades. Utility Model Content
