[0002] The fan blade is one of the core components of the wind turbine, accounting for about 15%-20% of the total cost of the fan, and the design of the fan blade will directly affect the performance and benefits of the fan. The fan blade has high requirements for materials, not only needs to have a lighter weight, but also needs to have high strength, corrosion resistance and fatigue resistance. In the production process of the blade, a blade mold is needed, the wind power blade mold is composed of a male mold and a female mold, the male mold is stationary, the female mold is first turned over by 180°, and then supported by a supporting oil cylinder and vertically lowered by a certain distance to complete the mold closing process of the male mold and the female mold. This process needs to be realized by a wind power blade mold overturning mechanism.

[0003] Patent No. CN205951329U discloses a novel wind power blade mold overturning side steel frame mechanism. The novel wind power blade mold overturning side steel frame mechanism is composed of a turnover beam and a turnover side steel frame main body. The steel frame main body is an integral inverted concave structure, the middle part of the bottom is an inner concave structure, and is supported by a detachable support fixed to the ground. The turnover is mainly completed by a detachable turnover beam. The stress side of the turnover beam is reinforced by a reinforcing rib, and the opposite side is reinforced by a box-shaped overall structure. The end is fixed with a double-nut bolt and the horizontal beam. The root is detached during transportation to reduce costs. The utility model on the one hand reduces the overall steel frame weight, reduces the mold closing height, reduces the requirements for the factory site, is beneficial to the development and application of super large wind power blade molds, and on the other hand reduces the amount of steel and the amount of ground fixing device, and reduces the cost. The structure is simple, easy to install and convenient, and improves the production efficiency. However, the stability of the device is easily affected by the weight of the mold when the mold is turned over by the turnover beam, and there is a possibility that the turnover side steel frame mechanism will vibrate or tilt during the turnover process, and the stability and balance are poor.
