The inner side end of the U-shaped frame 15 is rotatably connected with the roller brush 16, the roller brush 16 is used for brushing the shelf pipe 3, and therefore the two roller brushes 16 on the same side are located directly below the shelf pipe 3 on the same side. In order to avoid missing brushing, a small part of overlapping brushing is needed, and therefore the distance between the two roller brushes 16 on the same side is less than the length of the roller brush 16. The long bolts 17 are fixed on the front and rear surfaces of the outer side end of the U-shaped frame 15 and are upwardly fixed with the vertical plate 14, and the outer side end refers to the end close to the sliding rail 7. Preferably, the inclined supporting rod 25 is arranged between the long bolt 17 and the U-shaped frame 15.

[0030] The embodiment is described by taking red and white as an example. If the front paint box 11 contains red paint and the rear paint box 11 contains white paint, the first end of the two frame pipes 3 is respectively inserted into the two circular tubes 18, the fastening bolts 19 are tightened to clamp the frame pipes 3, the frame pipes 3 are fixed to the motor shaft of the motor 2, the support frame 5 is pushed to make the two support columns 4 respectively penetrate into the other end of the two frame pipes 3, the casters 6 of the support frame 5 are stopped, the counterweight 23 is placed on the bottom plate of the support frame 5 according to the situation, the controller starts the motor 2, the motor 2 drives the two frame pipes 3 to rotate, then the controller controls the lifting mechanism 12 to lift upward, the horizontal plate 13, the vertical plate 14, the U-shaped frame 15 and the roller brush 16 move upward together, when the roller brush 16 contacts the upper frame pipe 3, the lifting mechanism 12 stops for several seconds to make the roller brush 16 fully brush the surface of the frame pipe 3, the frame pipe 3 is always rotating, so that the paint can be uniformly brushed on the frame pipe 3, a small section of the front of the frame pipe 3 is brushed with red paint, a section of the middle is not painted, and a small section of the rear is brushed with white paint, after the section is brushed, the controller controls the lifting mechanism 12 to descend, the roller brush 16 moves downward away from the frame pipe 3 and is immersed in the paint in the paint box 11 again, at this time, the controller controls the motor roller 10 to move backward by a distance equal to the interval between the two roller brushes 16, that is, the rear end of the red roller brush 16 is just moved to the front end of the white roller brush 16, the red paint brushed twice and the white paint brushed twice have a small overlap, and the total length of the red paint brushed twice and the total length of the white paint brushed twice are equal to the set length of the paint color interval. The interval between the roller brushes 16 and the length of the paint color interval are set according to the requirements. The controller controls the lifting mechanism 12 to brush, when the first section of red paint and white paint is brushed, the controller controls the lifting mechanism 12 to descend to make the roller brush 16 be immersed in the paint in the paint box 11 again, then the controller controls the motor roller 10 to move backward by a distance of the length of each section of red paint or white paint (different paint color interval), to brush the next section, each section of red paint or white paint is brushed twice with an overlap, and the above process is repeated until the frame pipe 3 is completely brushed, two frame pipes 3 can be brushed at a time, two colors can be brushed, and the construction efficiency is greatly improved.
