[0002] Wind turbine tower refers to the tower structure used to support wind turbines. Wind turbines are usually composed of components such as wind rotors, gearboxes, and generators, and these components need to be installed at high places in order to fully utilize wind energy. Therefore, the main function of wind turbine towers is to provide stable support and a safe working environment. Wind turbine towers are usually made of concrete or steel and have a certain height so that wind turbines can be installed at a higher position from the ground. The design and construction of the tower need to consider many factors, including wind force, foundation conditions, weight and height. In addition, the tower needs to have sufficient strength and rigidity to resist the influence of wind and other external forces.

[0003] The roller frame is an auxiliary equipment used in mechanical processing. For example, it can be used in painting and is often used for the outer surface painting of cylindrical workpieces. When the current wind turbine tower painting roller frame is used, the adjustment of the roller frame is not convenient when supporting towers of different diameters. It is not convenient to adapt to towers of different diameters, which will affect the painting effect to a certain extent. Therefore, it needs to be improved. Utility Model Content
