[0042] Reference Figure 1 and Figure 2 A moving frame 51 is fixedly connected to the bottom of the first U-shaped plate 5, a third motor 52 is fixedly connected to the moving frame 51, a second gear 53 is fixedly connected to the output shaft of the third motor 52, and an annular rack 54 meshing with the second gear 53 is fixedly connected to the circular ring plate 1; when it is necessary to move the first U-shaped plate 5 to a suitable position, the third motor 52 is started, the third motor 52 drives the second gear 53 to rotate, so that the second gear 53 moves on the annular rack 54, and the third motor 52 drives the moving frame 51 and the first U-shaped plate 5 to move.

[0043] Working principle: When in use, start the lifting device to drive the circular plate 1 to move in the vertical direction through the rope 3 and the connecting plate 2, so that the circular plate 1 moves to a suitable position, and the first U-shaped plate 5 is driven to move along the edge of the circular plate 1 by the walking component, and the first U-shaped plate 5 drives the spraying device 4 to move. When it moves to the position to be sprayed, the scraping component is used to scrape and clean the position to be sprayed to scrape off the dirt and rust, and then the coating component is used to apply the rust remover to the position to be sprayed. After the rust remover reacts for a period of time, the flushing and drying component is used to flush the position to be sprayed first, and then the position to be sprayed is wiped dry. Finally, the spraying device 4 can be used to spray the position to be sprayed. By setting the switching component, the appropriate component can be switched to process the position to be sprayed;

[0044] When it is necessary to use the wire brush 7 to scrape and clean the position to be sprayed, the wire bundle 701 is brought into contact with the position to be sprayed, and the wire bundle 701 is moved back and forth to achieve scraping. The fixing ring 702 can prevent the scraped debris from falling to the root of the wire bundle 701 and being difficult to remove;

[0045] When the wire bundle 701 scrapes off dirt and debris, the first motor 11 is started to drive the fan blade 12 to rotate, and the fan blade 12 blows air outward through the T-shaped cavity 10. The air in the cavity 8 enters the T-shaped cavity 10 through the through hole 14, so that negative pressure is formed in the cavity 8, thereby forming suction at the opening of the cavity 8, and the scraped debris is sucked into the collection box 9 in the cavity 8, so as to achieve the purpose of collecting and scraping the debris;

[0046] In the process of absorbing debris through the collecting assembly, wind will blow out from the outlet of the T-shaped cavity 10, and the first connecting ball 17 will shake irregularly due to the wind. The shaking of the first connecting ball 17 is transmitted to the fixing ring 702 through the first connecting rope 15, and the shaking is transmitted between the fixing rings 702 through the second connecting rope 16. The shaking of the fixing ring 702 can make the debris trapped in the steel wire bundle 701 fall out to the outside or be absorbed into the cavity 8. The shaking of the first connecting ball 17 can also be transmitted to the second connecting ball 20 through the fourth connecting rope 19. The shaking between the second connecting balls 20 is transmitted through the fifth connecting rope 21. The shaking of the second connecting ball 20 can further prevent the debris from being trapped in the steel wire bundle 701.

[0047] When the rust remover needs to be applied to the spraying position, one of the rotating rollers 55 is brought into contact with the spraying position, and the rotating roller 55 is driven to roll back and forth by making the annular plate 1 do lifting and reciprocating motion. Since the two rotating rollers 55 are connected by the first pulley 26, the second pulley 27 and the transmission belt 28, the two rotating rollers 55 rotate synchronously, and the size of the first pulley 26 is larger than the second pulley 27, so the rotation speed of the rotating roller 55 located in the box body 29 is greater than the rotation speed of the other rotating roller 55, so that relative friction is generated between the two rotating rollers 55, and the rotating roller 55 located in the box body 29 will continuously provide the rust remover from the box body 29 to the rolling rotating roller 55;

[0048] After the rust removal is completed, the spraying position needs to be rinsed, and the water pump is started. The water pump pumps the water in the water tank into the horizontal pipe 33, and the water is sprayed from the nozzle to the spraying position to rinse off the dirt and rust remover. After the rinsing is completed, the sponge roller 31 is brought into contact with the spraying position, and the sponge roller 31 is driven to move up and down through the annular plate 1. The sponge roller 31 can absorb the water on the spraying position so as to quickly spray;

[0049] When it is necessary to clean the position to be sprayed, and the scraping component, coating component or flushing and drying component is applied to the position to be sprayed, the second motor 36 is started to drive the third rotating shaft 34 to rotate, and the third rotating shaft 34 drives the rotating plate 35 to rotate, and the rotating plate 35 can drive the mounting block 6, the second U-shaped plate 22 or the second rotating shaft 30 to rotate, so that the wire brush 7, the rotating roller 55 or the sponge roller 31 are directly opposite to the position to be sprayed, and the first electric push rod 37, the second electric push rod 39 or the third electric push rod 41 is started to drive the first moving block 38, the second moving block 40 or the third moving block 42 to move, so that the wire brush 7, the rotating roller 55 or the sponge roller 31 are in contact with the position to be sprayed, and the circular plate 1 can be lifted and reciprocated to drive the wire brush 7, the rotating roller 55 or the sponge roller 31 to clean, and the rotating shaft 24 is arranged to be rotatably connected to the second moving block 40, so that the coating component always maintains a state under the action of gravity, that is, the rust remover in the box body 29 will not pour out;

[0050] After the rotating roller 55 or the sponge roller 31 is aligned with the position to be sprayed by the switching assembly, the second electric push rod 39 or the third electric push rod 41 is started to drive the second moving block 40 or the third moving block 42 to move, so that the rotating roller 55 or the sponge roller 31 contacts the position to be sprayed, and at the same time, the second moving block 40 or the third moving block 42 can drive the first gear 49 and the top column 50 to move, so that the first gear 49 and the top column 50 move toward the support platform 48 and the vertical plate 45 at the same time, and the top column 50 contacts the vertical plate 45 first, and pushes the vertical plate 45 to move toward the position to be sprayed, so that the suction cup 47 moves toward the position to be sprayed. The suction cup 47 will be adsorbed on the position to be sprayed to fix the rack 48. Since the top column 50 is a spring column, the first gear 49 continues to move so that the top column 50 is compressed until the first gear 49 moves to a position meshing with the spur rack 48. When the rotating roller 55 or the sponge roller 31 is lifted and lowered, the first gear 49 moves on the spur rack 48, and the first gear 49 will rotate. The first gear 49 can drive the rotating roller 55 or the sponge roller 31 to rotate, so that the rotating roller 55 can evenly apply the rust remover to the position to be sprayed, so that the sponge roller 31 can fully absorb the water at the position to be sprayed.

[0051] When the first U-shaped plate 5 needs to be moved to a suitable position, the third motor 52 is started, and the third motor 52 drives the second gear 53 to rotate, so that the second gear 53 moves on the annular rack 54, and the third motor 52 drives the moving frame 51 and the first U-shaped plate 5 to move.

[0053] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
