[0034] Reference Figure 1 , Figure 2 and Figure 3 The heating assembly includes two rotating shafts 4, which are rotatably connected to both sides of the inner wall of the outer casing 1. This rotatable connection allows for flexible movement. A motor 3 is fixedly connected to one side of each rotating shaft 4, and two fixed plates 6 are fixedly connected to the other side. A movable column 7 is rotatably connected to the front end of each fixed plate 6. A fixed plate 8 is fixedly connected to the outside of the movable column 7. A movable column 9 is fixedly connected to the front end of the fixed plate 8. A motor 10 is fixedly connected to the outside of the movable column 9.

A heating plate 12 is fixedly connected to one end of the ball joint 11, ensuring that the heating plate 12 can be flexibly adjusted as needed to achieve efficient heating. This provides stable and efficient heating performance, adapting to different working conditions.
[0035] Reference Figure 1 and Figure 3 and Figure 5The conveying assembly includes two water pumps 31, with hoses 29 fixedly connected to the top and bottom of each pump 31 to ensure smooth liquid flow. A connecting pipe 32 is fixedly connected to one side of each pump 31, and a material bucket 30 is fixedly connected to one side of the connecting pipe 32, allowing the material to be drawn from the bucket and conveyed to other parts of the equipment. The hoses 29 are fixedly connected to the top two sides of the paint spraying box 21.

[0037] Working Principle: The electric slide rail 16 and extension plate 18 installed on the inner wall of the outer casing 1 allow the spraying equipment to move automatically along the steel structure surface. The combination of the extension plate 18 and telescopic plate 19 allows the spraying section to be automatically adjusted in different positions. The fixed column 20 provides stability. The paint tank 21 has two spaces inside, one for cleaning and the other for paint. During equipment use, work or cleaning can be performed according to the current situation. A heating component is installed inside the outer casing 1, which includes two rotating shafts 4, rotatably connected to both sides of the inner wall of the outer casing 1. Driven by motor 3, the rotating shafts 4 begin to rotate, causing the fixed plate 6 to move. The fixed plate 6 is connected to the fixed plate 8 via a movable column 7. The movable column 9 is connected to one side of the fixed plate 8 and is connected to motor 10. Motor 10 drives the ball joint 11 and the heating plate 12, ultimately heating the heating plate 12. The function of the heating component is to provide a suitable temperature to ensure the fluidity and adhesion of the paint during the spraying process.
[0038] The delivery assembly consists of two water pumps 31. The water pumps 31 deliver the paint to the paint spraying tank 21 through the hose 29 and the connecting pipe 32. Inside the paint spraying tank 21, the paint is guided to multiple nozzles 27 through the fixed pipe 22 and the paint spraying box 23. The nozzles 27 spray the paint evenly onto the surface of the steel structure to be treated by spraying force. The spring 25 and the limiting post 28 of the paint spraying tank 21, together with the mesh sleeve 26, enable precise control of the spraying operation and prevent excessive or uneven spraying of paint. During the spraying process, the heating plate 12 is driven by the motor 10 and the ball joint 11. The position of the heating plate 12 is adjusted so that it heats the paint before spraying. Heating the paint helps to improve the adhesion of the paint and enhance the anti-corrosion effect.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
