[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to the attached Figure 1 -attached Figure 2 As an embodiment provided by the present utility model: a coating device with wear-resistant, corrosion-resistant and high-temperature-resistant inner walls, including a U-shaped table 1. A heat-insulating layer paint box 11 is fixedly connected to the rear part on the right side inside the U-shaped table 1. A wear- and corrosion-resistant paint box 9 is fixedly connected to the middle part on the right side of the inner wall of the U-shaped table 1. A coating paint box 8 is fixedly connected to the front side on the right part inside the U-shaped table 1. A material pump 10 is connected to the left sides of both the coating paint box 8 and the wear- and corrosion-resistant paint box 9. The output end of the material pump 10 is connected to a telescopic pipe 12. The front end of the telescopic pipe 12 is connected to a shunt pipe 13. Nozzles 16 are connected to the bottom ends of the outer walls of the shunt pipe 13. Servo motors II 22 are fixedly connected to the right sides of both the coating paint box 8 and the wear- and corrosion-resistant paint box 9. The output ends of the servo motors II 22 are fixedly connected to rotating rods 23. Rotating blades 21 are fixedly connected to the outer walls of the rotating rods 23. A disassembly and assembly mechanism 2 is arranged inside the left side of the U-shaped table 1. The disassembly and assembly mechanism 2 is used to facilitate the fixation and disassembly of steel pipes. Support plates II 26 are fixedly connected to the inner bottom sides of the U-shaped table 1. C-shaped holes 25 are opened at the tops of the support plates II 26. The inner sides of the C-shaped holes 25 are engaged with the outer walls of the telescopic pipes 12. An electromagnetic valve 17 is connected to the left side of the outer wall of the telescopic pipe 12.

[0030] Specifically, a wear- and corrosion-resistant paint box 9 is carefully installed in the middle part on the right side of the inner wall of the U-shaped table 1. This paint box is used to store and supply a special paint, which has excellent wear and corrosion resistance. The coating paint box 8, like the wear- and corrosion-resistant paint box 9, also has the characteristics of being easy to maintain and clean. These material pumps 10 have strong suction and conveying capabilities, and can quickly and accurately pump the paint out of the paint box and transport it to the required places through pipelines. The design of the shunt pipe 13 takes into account the fluidity and uniform distribution of the paint, ensuring that each nozzle 16 can obtain sufficient paint.

[0031] Please refer to the attached Figure 3, the disassembly and assembly mechanism 2 includes a first support plate 201. The bottom of the first support plate 201 is fixedly connected to the inner left side of the U-shaped table 1. Both the front and rear sides of the top of the first support plate 201 are fixedly connected with hollow plates 210. A circular groove 209 is provided inside the hollow plate 210. A circular slide bar 207 is slidably connected to the inner side of the circular groove 209. A hollow column 211 is fixedly connected to the inner side of the circular slide bar 207. A spring 206 is fixedly connected to the inner side of the hollow column 211. The other end of the spring 206 is fixedly connected to a T-shaped column 203. A column steel pipe 202 is clamped between adjacent T-shaped columns 203. A steel bar 204 is clamped between the outer wall of the column steel pipe 202 and the T-shaped column 203. A bolt 205 is threadedly connected to the front top of the steel bar 204. A first servo motor 208 is fixedly connected to the front of the front hollow plate 210. The output end of the first servo motor 208 is fixedly connected to the corresponding hollow column 211. L-shaped pipes 24 are connected to the front sides of the coating tank 8 and the corrosion-resistant coating grinding tank 9. A threaded cap 20 is threadedly connected to the top outer wall of the L-shaped pipe 24.

[0032] Specifically, the first support plate 201 serves as the foundation of the entire structure, and the hollow plates 210 are carefully installed on both the front and rear sides of its top. These two hollow plates 210 are not simple flat plates. Circular grooves 209 are ingeniously provided inside them. Circular slide bars 207 are slidably connected to the inner sides of the circular grooves 209, and these slide bars can freely slide within the grooves. A hollow column 211 is fixedly connected to the inner side of the circular slide bar 207. Such a design enables the entire sliding component to move horizontally while maintaining the stability of the structure. The design of the T-shaped columns 203 enables them to tightly hold the column steel pipes 202 and maintain their stability through the elastic force of the spring 206.

[0033] Please refer to the attached Figure 1 - attached Figure 2 , a direction hole 6 is provided on the right side of the U-shaped table 1. Lighting lamps 7 are fixedly connected to the inner top of the direction hole 6. A handle 19 is fixedly connected to the top left side of the outer wall of the telescopic pipe 12. An anti-slip strip 18 is fixedly connected to the top outer wall of the handle 19. A storage battery 5 is fixedly connected to the inner bottom of the direction hole 6. A fluorescent plate 4 is fixedly connected to the front bottom of the U-shaped table 1. A long groove 14 is provided on the inner bottom left side of the inner wall of the U-shaped table 1. A bottom plate 3 is fixedly connected to the bottom of the U-shaped table 1. A controller 15 is fixedly connected to the left side of the U-shaped table 1. The controller 15 is electrically connected to the material pump 10, the electromagnetic valve 17, the second servo motor 22, and the first servo motor 208 respectively.

[0034] Specifically, through the inner top of the direction hole 6, we carefully installed the lighting lamp 7. These lighting lamps 7 not only provide the necessary illumination, enabling the operator to see more clearly when handling the paint, but also ensure the uniform distribution of light in the working area, avoiding operation errors caused by insufficient light. The design of the lighting lamp 7 fully considers durability and energy conservation. The storage battery 5 provides a stable power supply for the entire system, ensuring the normal operation of the lighting lamp 7 and other devices. The fluorescent plate 4 can emit soft light in a dim environment, providing additional illumination and guidance for the operator. The controller 15 is the core component of the entire system, responsible for controlling the operation and adjustment of the lighting lamp 7 device.

[0035] Working principle: When it is necessary to protect the steel pipe against wear and corrosion, first, cooperate with the disassembly and assembly mechanism 2 to stabilize the steel pipe. Then, according to the need, pick up the handle 19 respectively for different coatings on the coating tank 8 for wear-resistant and corrosion-resistant coatings, the grinding and corrosion-resistant coating tank 9, and the insulation layer coating tank 11. At this time, start the material pump 10. Through the extension of the telescopic pipe 12, cooperate with the nozzle 16 connected to the shunt pipe 13 to contact the steel pipe. Then start the solenoid valve 17, and cooperate with the nozzle 16 to sequentially coat different coatings on the inner side of the steel pipe from the coating tank 8 for wear-resistant and corrosion-resistant coatings, the grinding and corrosion-resistant coating tank 9, and the insulation layer coating tank 11. The ion nitriding process can be configured in the coating device, thereby improving the wear resistance and corrosion resistance of the inner wall of the steel pipe.

[0036] At the same time, adding an overcoat further enhances the bonding strength between the coating and the steel pipe body, preventing the coating from peeling off. The setting of the lubricating layer reduces the fluid friction resistance and improves the conveying efficiency. The setting of the insulation layer reduces the heat loss and improves the energy utilization efficiency. Then, the spring 206 inside the hollow column 211 ejects the T-shaped column 203, which is engaged with both sides of the column steel pipe 202. Subsequently, wind the steel bar 204 around the junction of the T-shaped column 203 and the column steel pipe 202, and tighten the steel bar 204 through the bolt 205 to avoid falling off. Finally, start the servo motor 1 208 to drive the corresponding hollow column 211, so that the circular slide 207 rotates along the inner side of the circular groove 209, and at the same time drives the column steel pipe 202 to rotate, making the paint more evenly sprayed during the spraying process. Therefore, it ensures that the disassembly and assembly operation of the steel pipe can be completed in a short time, facilitating the operator to protect the steel pipe, and at the same time making the paint coating more uniform and improving the use effect of the paint.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 perform equivalent replacements on some of the technical features.
