Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blades, in particular to a wind turbine blade cap positioning device. Background Art

[0002] Wind turbine blades are composed of the upper shell PS surface, the lower shell SS surface, the beam and the web. Among them, since the beam is one of the main load-bearing structures of the blade, it bears most of the bending load of the blade. In the process of blade production, it is necessary to lay the beam to the specified position according to the involved. If the positioning of the beam deviates, it will lead to a reduction in the stiffness and stability of the blade, thereby causing the entire structure of the blade to fail, resulting in major quality problems. When laying the beam, a beam cap positioning tool is used. When using the existing beam cap positioning tool, when laying the beam, one side of the support frame is stuck on the small flange of the mold, and the lower end of the support frame is provided with an arc surface matching the mold surface. The operator needs to fix the tooling for a second time, and then operate the crane to place the blade beam to the specified position. Since the shape of the support frame, the arc surface and other parameters are fixed, the existing beam cap positioning tool can only be applied to beams of fixed size. Utility Model Content
