Technical Field

[0001] The utility model relates to the technical field of steel structure coating, and more specifically, to a steel structure surface coating device. Background Art

[0002] Steel structure is one of the common structures in buildings. During construction, the surface of the steel structure needs to be cleaned and then painted to protect the steel structure. In the process of treatment, it is often necessary to concentrate on cleaning the surface of the steel structure. After a batch of steel structures are all cleaned, they can be painted. However, when the interval between painting and cleaning is long, it may cause the surface of the steel structure to rust or dust to fall. At this time, it is necessary to use cleaning equipment to clean the steel structure again, which is more troublesome. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

An air outlet pipe 8 is fixedly connected to the top of the air outlet pipe 8, and a second air blowing pipe 11 is fixedly connected to the bottom end of the second air blowing pipe 11. A nozzle head 12 is fixedly connected to the rear side of the support frame 1. A servo motor 14 is fixedly connected to the output shaft of the servo motor 14. A grinding roller 15 is fixedly sleeved on the right side of the support frame 1. A connecting pipe 18 is fixedly connected to the bottom end of the connecting pipe 18. A spray head 19 is fixedly connected.

[0021] The coating liquid output end of the coating device is connected to the connecting pipe 18, and then the servo motor 14 is started to drive the grinding roller 15 to rotate to grind the rust on the surface of the steel structure. When the grinding roller 15 rotates, it drives the rotating rod 3 to rotate, thereby driving the movable sleeve rod 4 to move along the axial direction of the piston cylinder 6, and then driving the piston rod 5 to move up and down in the inner cavity of the piston cylinder 6. When the piston rod 5 moves in the direction of the piston cylinder 6, the air in the inner cavity of the piston cylinder 6 is pushed out along the air outlet pipe 8 to the inner cavity of the blowing pipe 2 11, and then the air is blown out to the surface of the steel structure through the nozzle 12 at the bottom end of the blowing pipe 2 11, so that the rust polished by the grinding roller 15 is blown away. After the grinding roller 15 and the blowing pipe 2 11 have processed the surface of the steel structure, the coating liquid is directly sprayed onto the surface of the steel structure through the spray head 19, and there is no need to process the rust on the surface of the steel structure in advance, thereby improving the efficiency of cleaning and coating.

[0022] Among them, the top of the piston cylinder 6 is fixedly connected to a one-way air inlet valve 7, the top of the air outlet pipe 8 is fixedly connected to a one-way air outlet valve 9, and the left side of the air outlet pipe 8 is fixedly connected to a blowing pipe 10;

[0023] When the piston rod 5 moves downward in the inner cavity of the piston cylinder 6, the external air is drawn into the inner cavity of the piston cylinder 6 through the one-way air inlet valve 7. When the piston rod 5 moves upward in the inner cavity of the piston cylinder 6, the air in the inner cavity of the piston cylinder 6 is output along the air outlet pipe 8 to the inner cavity of the blowing pipe 10, thereby realizing the processing of fallen objects on the surface of the steel structure, such as some dust and fallen leaves, to prevent these foreign objects from affecting the grinding of the grinding roller 15.

[0024] Among them, the top of the front side of the support frame 1 is fixedly connected with a guide ring 13, and the piston rod 5 is movably sleeved in the inner cavity of the guide ring 13;

[0025] The piston rod 5 is movably sleeved in the inner cavity of the guide ring 13, so that the piston rod 5 can be positioned and guided by the guide ring 13, so that when the rotating disk 2 drives the rotating rod 3 to rotate, it can drive the movable sleeve rod 4 to rise and fall stably.

[0026] Among them, a limit plate is provided on the front side of the rotating rod 3, and the limit plate is located on the front side of the movable sleeve rod 4;

[0027] The movable sleeve rod 4 can be limited by the limiting plate on the front side of the rotating rod 3, thereby preventing the movable sleeve rod 4 from falling off the surface of the rotating rod 3 when the rotating rod 3 drives the movable sleeve rod 4 to move.

[0028] Among them, the top of the support frame 1 is fixedly connected to a handle 16, and the right side of the support frame 1 is fixedly connected to a counterweight block 17;

[0029] Through the handle 16 at the top of the support frame 1, the staff can hold the handle 16 to drive the support frame 1 to move, and through the setting of the counterweight block 17, the counterweight block 17 counterweights the support frame 1, so that the support frame 1 remains balanced when the staff holds the handle 16 to drive the support frame 1 to move.

[0030] Among them, the piston rod 5 is fitted with the inner wall of the piston cylinder 6, and there are four nozzles 12. The four nozzles 12 are fixedly connected to the bottom ends of the blowing pipe 10 and the blowing pipe 2 11 respectively. The nozzle 12 at the bottom end of the blowing pipe 10 is installed obliquely at the bottom end of the blowing pipe 10;

[0031] By fitting the piston rod 5 against the inner wall of the piston cylinder 6, the piston cylinder 6 can stably extract or push the air in the inner cavity of the piston rod 5, and then the nozzle head 12 is tilted and installed at the bottom end of the blowing pipe 10, so that the nozzle head 12 can blow foreign matter away from the grinding roller 15.

[0032] The working principle and usage process of the present invention are as follows: connect the coating liquid output end of the coating device to the connecting pipe 18, then hold the handle 16 to make the grinding roller 15 fit the surface of the steel structure, then start the servo motor 14 to drive the grinding roller 15 to rotate to grind and remove rust on the surface of the steel structure, when the grinding roller 15 rotates, it drives the rotating disk 2 to rotate, and drives the rotating rod 3 to rotate through the rotating disk 2, and then drives the movable sleeve rod 4 to move, through the movement of the movable sleeve rod 4 and the positioning and guidance of the piston rod 5 by the guide ring 13, so that the piston rod 5 is lifted and lowered in the inner cavity of the piston cylinder 6, when the piston rod 5 descends in the inner cavity of the piston cylinder 6, the external air is drawn into the inner cavity of the piston cylinder 6 through the one-way air inlet valve 7, when the piston rod 5 moves upward in the inner cavity of the piston cylinder 6, the air in the inner cavity of the piston cylinder 6 is output along the air outlet pipe 8 to the inner cavity of the blowing pipe 1 10 and the blowing pipe 2 11;

[0033] The nozzle 12 at the bottom of the air blowing pipe 10 blows out the fallen leaves and other debris on the surface of the steel structure, and then the nozzle 12 at the bottom of the air blowing pipe 2 11 blows on the surface of the steel structure, thereby blowing out the debris dropped by the grinding roller 15;

[0034] Then the coating liquid is sprayed onto the surface of the steel structure through the spray head 19 .
