[0002] During the production process of wind turbine blades, they need to go through processes such as grinding and painting. However, as the capacity of wind turbine generators increases, the length of wind turbine blades is also getting longer and longer. Therefore, when performing the above processes, large wind turbine blades need to be flipped using a flipping device to meet processing requirements.

[0003] The existing patent (publication number CN217943282U) discloses a wind turbine blade flipping device, which is used to support the support column by setting a support frame, and to support the placement frame and facilitate the rotation of the placement frame by setting a support column, and to place the blades to be processed by setting a placement frame, and to clamp and fix the blades placed inside the placement frame by setting a movable plate and a spring, so as to improve the stability of the blades during processing and prevent the blades from falling from the inside of the placement frame. By setting a rotating disk, a rotating ring and a connecting column, it is convenient to rotate the placement frame, so as to facilitate the rotation of the blades, and replace the lifting with manual operation. The existing wind turbine blade flipping device can flip the blades of uniform length, and needs to be manually transported to the placement frame for flipping and removal. To this end, we propose a wind turbine blade flipping device to solve the above-mentioned problems. Utility Model Content
