Description

Technical Field

[0001] This utility model relates to the field of wind power blades, and in particular to a suction cup lifting device for wind power blade prefabrication. Background Technology

[0002] An existing patent (publication number: CN222475909U) proposes a suction cup lifting device for prefabricated wind turbine blades. It includes a support frame, with a bidirectional hydraulic telescopic rod fixedly connected to the inner wall of the support frame. Each telescopic end of the bidirectional hydraulic telescopic rod is fixedly connected to a moving block. Two first-level wrapping frames are located below the support frame, and each first-level wrapping frame has an electric telescopic rod fixedly connected to its inner wall. However, in this device, where "two first-level wrapping frames are located below the support frame," the equipment relies on the support frame under the triangular lifting plate to lift the wind turbine blades. Because the support frame is at a fixed angle, if the orientation of the wind turbine blades needs to be adjusted, the operator must manually approach the blades to adjust the orientation, posing a certain safety hazard. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a wind turbine blade prefabrication suction cup lifting device. This device utilizes a toothed clamp at the front of a clamp support frame to support the bottom of the wind turbine blade. A screw motor at the lower part of the clamp support frame drives a suction cup screw to rotate, causing the suction cup screw to lift and lower an electromagnetic chuck at the front of the suction cup frame. An angle handle on the side of the suction cup base allows for angle adjustment of the electromagnetic chuck. This process eliminates the need for an operator to approach and rotate the device, thereby increasing equipment safety.
