Description

Technical Field

[0001] The utility model relates to the technical field of wind power blade surface grinding, in particular to a frame for a wind power blade surface grinding machine. Background Technique

[0002] Energy is the primary driving force for the development of human society and economic growth. Currently, among renewable energies, except for hydropower, wind power is the most commercially exploitable. In recent years, China's wind power industry has also developed rapidly, and China has become the country with the largest scale and fastest growth rate of global wind power generation. However, the development of China's wind power industry's equipment manufacturing industry is slow, especially the grinding process of wind power blades. According to investigations, the blade length of China's wind turbines ranges from 40 meters to 95 meters, reaching 143 meters in 2024. The mass of a single blade exceeds 50 tons, and the root diameter exceeds 5 meters. It can be seen that the size of wind power blades is very large and the outer surface is very complex and variable.

[0003] When using a grinding device to grind the surface of a wind power blade, a liftable and telescopic frame is required to drive the grinding device to move to the position on the surface of the wind power blade to be ground. Currently, the existing methods include using cables and drag chains combined with cylinders to achieve the horizontal movement or vertical movement of the frame. This method has a complex structure and is inconvenient for maintenance, and cannot achieve high-precision position control, resulting in low grinding efficiency. Or, a hydraulic cylinder is used on the horizontal telescopic arm in the frame to lift the grinding head. However, this method requires the accuracy of the hydraulic oil to be high enough. However, during the grinding process, a lot of grinding dust will be generated, and it is difficult to ensure the accuracy of the hydraulic oil, which will also cause deviations in the position and speed of the hydraulic cylinder, resulting in inaccurate position control and low grinding efficiency. Or, a robot is used to drive a pneumatic grinding machine to grind the wind power blade. However, this method has poor mobility on the one hand and requires a special track to be set up to cooperate with the movement of the robot, resulting in a complex overall equipment structure and high costs.
