Technical Field
[0001] This utility model relates to the field of steel structure processing technology, and specifically to a spraying device for anti-corrosion coating on steel structure surfaces. Background Technology
[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are typically characterized by light weight, good seismic performance, high degree of industrialization, short construction period, strong plasticity, energy saving and environmental protection, and are widely used in various fields. Common steel structures include square steel, I-beams, steel plates and welded components of the above structures. Steel structures are easily affected by the external environment and will rust when exposed. Therefore, steel structures need to be coated with anti-corrosion coating after production and processing.
[0003] According to Chinese Patent Publication No. CN222076924U, "A Spraying Device for Anti-corrosion Coating on Steel Structure Surface," the device is mainly assembled and fixed using connecting components. This allows for two assembly methods between the base and the operating table. When the operating table and base are assembled vertically, the handle on the side wall of the operating table, in conjunction with the casters at the bottom of the base, facilitates the movement of the entire device, making the adjustment of the device's position more time-saving and labor-saving. When the operating table and base are assembled horizontally, the handle provides stable support and fixation for the operating table. The operating slot within the operating table can be used for placing the steel structure during the anti-corrosion coating spraying process, eliminating the need for a separate operating table, saving on construction time, simplifying operation steps, and improving the efficiency of anti-corrosion coating spraying on steel structures.
[0004] Anti-corrosion coatings are usually applied to steel structures manually. However, when the steel structure is large in size and shape, the application process is laborious and can easily create blind spots. In some cases, the application process takes place outdoors, which can cause dust to come into contact with the coating and stick to the steel structure, resulting in poor coating performance.
[0005] Therefore, a spraying device for anti-corrosion coating on steel structure surface is proposed to solve the problem that in some cases, the spraying process is carried out outdoors, which causes dust to come into contact with the coating and stick to the steel structure, resulting in poor coating effect. Utility Model Content
[0006] The technical problem to be solved by this utility model is that in some cases the spraying process is carried out outdoors, which causes dust to come into contact with the paint and stick to the steel structure, resulting in poor paint spraying effect. Therefore, a spraying device for anti-corrosion coating on steel structure surface is proposed.
[0007] The technical solution adopted by this utility model to solve the technical problem is: a spraying device for anti-corrosion coating on steel structure surface, including a fixed plate, a bracket fixedly connected to the upper end of the fixed plate, and a connecting plate fixedly connected to the upper end of the bracket; a first motor fixedly connected to one side of the upper end of the connecting plate; a first screw fixedly connected to the output end of the first motor; a movable plate threadedly connected to the first screw; support plates fixedly connected to all four sides of the bottom end of the movable plate; a second motor fixedly connected to one side of the support plate; a second screw fixedly connected to the output end of the second motor; and a slider threadedly connected to the second screw. A third screw is rotatably connected to the upper part of the plate. A movable block is threaded onto the third screw. A paint spray head is fixedly connected to the bottom end of the movable block. A connecting pipe is fixedly connected to the upper end of the movable block. The connecting pipe is fixedly connected to an external paint supply device. A folding baffle is fixedly connected to the bottom end of the movable plate. A U-shaped frame is fixedly connected to the bottom end of the folding baffle. The U-shaped frame contacts the fixed plate. A storage frame contacts the upper end of the fixed plate. Ventilation holes are evenly distributed on one side of the storage frame. An annular cover is fixedly connected to the storage frame at the ventilation holes. A baffle is fixedly connected inside the annular cover. A guide fan is rotatably connected to the baffle.
[0008] As a preferred technical solution of this utility model, a limiting groove is provided on the fixing plate, and a fourth motor is fixedly connected to one side of the fixing plate at the limiting groove. A fourth screw is fixedly connected to the output end of the fourth motor, and a pad is threadedly connected to the fourth screw. The pad is rotatably connected to the storage frame. By setting the fourth motor to drive the fourth screw to rotate, the pad can be moved. At the same time, there is a connection between the pad and the storage frame, so the movement of the pad can drive the movement of the storage frame, thereby making the opposite side of the two storage frames in an unfolded state.
[0009] As a preferred technical solution of this utility model, a pad strip is fixedly connected to one side of the storage frame. The pad strip has a triangular structure. By setting the pad strip, which is made of rubber material, it provides collision cushioning and reduces the chance of dust entering the storage frame and falling out.
[0010] As a preferred technical solution of this utility model, the upper end of the fixed plate is fixedly connected with protrusions on all four sides. The protrusions are provided with through holes and spring pins are inserted into the through holes. The ends of the spring pins are in contact with the U-shaped frame. By setting the spring pins, the U-shaped frame can be limited, thereby increasing the contact effect between the fixed plate and the U-shaped frame.
[0011] As a preferred technical solution of this utility model, a first groove is provided on the movable plate, and a dustproof net is fixedly connected in the first groove. By setting the dustproof net, the entry of subsequent dust is reduced.
[0012] This utility model has the following advantages: by placing the steel structure to be coated on the upper side of the fixed plate or the storage frame, and then unfolding the folding cover so that the U-shaped frame contacts the fixed plate to form a semi-closed state, and by rotating the guide fan, the air and dust between the fixed plate and the moving plate are forced into the storage frame, thereby achieving the effect of cleaning environmental dust. This can reduce the generation of bubbles and bumps caused by the contact between the steel structure coating and the dust of the external environment, and improve the coating effect.

[0018] Please refer to the following: Figs. 1-3The device shown is a spraying device for anti-corrosion coating on steel structure surface, including a fixed plate 1, a bracket fixedly connected to the upper end of the fixed plate 1, and a connecting plate 2 fixedly connected to the upper end of the bracket. A first motor is fixedly connected to one side of the upper end of the connecting plate 2. The first motor drives a first screw 3 to rotate, which can cause a movable plate 4 to move up and down. The output end of the first motor is fixedly connected to the first screw 3, and the movable plate 4 is threadedly connected to the first screw 3. Support plates 5 are fixedly connected to all four sides of the bottom end of the movable plate 4. A second motor is fixedly connected to one side of the support plate 5. The second motor drives a second screw 6 to rotate, which can cause a slider 7 to move laterally on the bottom side of the movable plate 4. Then, a third screw 8 rotates, which can cause a movable block 9 to move vertically on the bottom side of the movable plate 4, thereby achieving the effect of controlling the free movement of the spray head 10. The output end of the second motor is fixedly connected to the second screw 6, and the slider 7 is threadedly connected to the second screw 6. (Slider 7 - A third motor is installed on the side, and the output end of the third motor is fixedly connected to the third screw 8. The third screw 8 is rotatably connected to the slider 7. The third screw 8 is threadedly connected to the moving block 9. The bottom end of the moving block 9 is fixedly connected to the paint spray head 10. The upper end of the moving block 9 is fixedly connected to the connecting pipe 11. The connecting pipe 11 is fixedly connected to the external paint supply equipment. The bottom end of the moving plate 4 is fixedly connected to the folding baffle 12. The bottom end of the folding baffle 12 is fixedly connected to the U-shaped frame 13. The U-shaped frame 13 is in contact with the fixed plate 1. The upper end of the fixed plate 1 is in contact with the storage frame 14. Ventilation holes 15 are evenly opened on one side of the storage frame 14. The storage frame 14 is fixedly connected to the annular cover 16 at the ventilation hole 15. The annular cover 16 is fixedly connected to the baffle 17. The baffle 17 is rotatably connected to the guide fan 18. During the painting process, the folding baffle 12 can be opened, and the U-shaped frame 13 can be in contact with the fixed plate 1, thereby forming a semi-sealed space.
[0019] The storage frame 14 is rotatably connected to the pad 19, and the pad 19 is threadedly connected to the fourth screw 20. The fourth screw 20 is fixedly connected to the output end of the fourth motor. The fourth motor is fixedly connected to one side of the limiting groove, which is located on the fixed plate 1. By driving the fourth screw 20 to rotate through the fourth motor, the pad 19 can be moved, thereby causing the two storage frames 14 to unfold.
[0020] The pad strip 21 is fixedly connected to one side of the storage frame 14. The pad strip 21 has a triangular structure. By setting the pad strip 21, the amount of dust entering the storage frame 14 can be reduced and removed from the storage frame 14.

[0022] The movable plate 4 has a first groove, and a dustproof net 24 is fixedly connected in the first groove. By setting the dustproof net 24, the airflow from the external environment can be reduced from entering between the fixed plate 1 and the movable plate 4.
[0023] Working principle: The steel structure to be painted is placed on the storage frame 14, so that the folding cover 12 is extended and the U-shaped frame 13 contacts the fixed plate 1. Then, the spring pin 23 is pulled to limit the U-shaped frame 13. Then, the fourth motor is started to drive the pad 19 and the storage frame 14 to move. At this time, the two storage frames 14 are not in contact. Then, the guide fan 18 is started to intensify the airflow circulation between the moving plate 4 and the fixed plate 1, and the dust in the air in the folding cover 12 gradually enters the storage frame 14. Then, by using the rotation of the first screw 3, the second screw 6 and the third screw 8, the paint head 10 can move on the bottom side of the moving plate 4, and the paint is supplied to the paint head 10 through the external paint supply equipment and sprayed out to contact the steel structure.
