Description

Technical Field

[0001] The invention relates to the field of tower painting equipment, in particular to a painting device for wind power tower production. Background Art

[0002] During the production process of wind turbine towers, protective paint needs to be sprayed on the outer wall of the wind turbine tower to extend the service life of the wind turbine tower. Existing wind turbine tower outer cylinder painting equipment mostly cooperates with a roller frame in the rotating process, moves a nozzle at a fixed angle on a moving track, and simultaneously makes the wind turbine tower rotate through the roller frame to spray paint on the outer wall of the wind turbine tower. When the existing painting equipment is in use, the painting platform moves back and forth continuously, which not only sprays paint inefficiently but also causes a lot of energy waste.

[0003] According to the patent document with the existing publication number CN217527955U, a flexible outer cylinder painting equipment for wind power tower is disclosed, which includes a roller frame and a cylinder body, both sides of the cylinder body are provided with electric tracks, a six-axis mechanical arm is slidably provided on the electric track, one end of two sets of the electric tracks are connected by a translation track, and an angle measuring mechanism is provided at the center of the bottom of the roller frame. When the technical solution is in use, the six-axis mechanical arm is used to paint the outer wall of the wind power tower, and two sets of U-shaped electric tracks are used to spray the outer wall of the wind power tower. In the moving state, one-sixth of the painting work on each side of the roller frame, a total of one-third, can be completed. When the painting of the outer wall of the wind turbine tower is completed, the roller frame makes the wind turbine tower rotate a total of half a circle. At the same time, the six-axis robotic arm that adjusts its position through intermittent motion greatly speeds up the painting efficiency of the outer wall of the wind turbine tower and reduces the energy consumption required for painting the wind turbine tower. Regarding the above technical solution, although it reduces energy consumption, it is impossible to adjust the contact position of the roller and the cylinder according to the painting of the inner and outer walls of the tower during use, which is inconvenient during use.
