[0002] Pipelines are devices made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. In desert oil and gas fields, oil and gas need to be transported over long distances through pipelines. However, after long-term use, pipelines may experience hydrogen sulfide corrosion perforation, weld corrosion perforation, sand hole perforation, hydrate freezing blockage, and other phenomena, thus requiring anti-corrosion treatment of the pipeline surface.

[0003] Existing technology CN221171344U discloses a pipe anti-corrosion coating device, including a pipe body, a pneumatic guide rail, a spraying air pump, a storage tank, and a base. A fixed bracket is provided on the upper side of the base, and a second rotating shaft is installed through the fixed bracket. A reducer is provided at the front end of the second rotating shaft, and a drive motor is mounted in front of the reducer. A first rotating shaft is provided on the left side of the second rotating shaft, and a driven roller is mounted on the first rotating shaft. The pipe body is placed on the driven roller and the drive roller. A pneumatic guide rail is provided on the right side of the upper end face of the base. However, when the above-mentioned coating device coats the pipe, it needs to use a spraying pump to transport and spray the anti-corrosion material. The spraying area is relatively small, resulting in a long spraying time and high spraying cost.

[0004] Therefore, there is an urgent need to provide a pipeline anti-corrosion coating device that reduces spraying time and lowers spraying costs compared to existing technologies. Utility Model Content

[0005] This utility model solves the technical problems existing in the prior art and provides a pipe anti-corrosion coating device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pipe anti-corrosion coating device includes a coating box, which is hollow inside and open at the top. Two rotating rods are rotatably connected inside the coating box. A coating roller is fixedly installed on the outer wall of each rotating rod. The same end of the two rotating rods protrudes from the side wall of the coating box. The end of the rotating rod protruding from the side wall of the coating box is connected to a rotating assembly, which drives all the coating rollers to rotate in the same direction. A discharge pipe is provided on the side wall of the coating box. The coating box is filled with anti-corrosion material.

[0007] Furthermore, the rotating assembly includes a motor, two drive wheels and a drive belt. The ends of the two rotating rods that protrude from the side wall of the paint box are respectively fixedly connected to one of the drive wheels. The drive belt is sleeved on the outer wall of the two drive wheels. The end of one of the rotating rods is connected to the output end of the motor.

[0008] Furthermore, a mounting plate is fixedly connected to the side wall of the paint box, and the motor is fixedly connected to the upper wall of the mounting plate.

[0009] Furthermore, a bearing is fitted onto the outer wall of the rotating rod, and the bearing is embedded in the side wall of the coating box.

[0010] Furthermore, the bottom of the coating box is inclined, and the discharge pipe is set at the lowest point of the bottom of the coating box.

[0011] Furthermore, the end of the discharge pipe away from the coating box is threadedly connected to a sealing cap.

[0012] Furthermore, the inner sidewalls of the coating box are provided with an anti-stick coating.

[0022] The technical solution of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] like Figure 1 As shown, this utility model provides a pipe anti-corrosion coating device, including a coating box 1. The coating box 1 has a hollow interior and an open top. Two rotating rods 6 are rotatably connected inside the coating box 1. Coating rollers 8 are fixedly connected to the outer walls of the two rotating rods 6. The two coating rollers 8 are rotatably connected inside the coating box 1. The axes of the two coating rollers 8 are parallel. The tops of the two coating rollers 8 extend out of the upper surface of the coating box 1. The pipe body 10 is placed on the tops of the two coating rollers 8. The same end of the two rotating rods 6 passes through the side wall of the coating box 1 and is rotatably connected to the side wall of the coating box 1 through bearings 7. The two bearings 7 are both sealed bearings. A rotating component is provided at one end of the two rotating rods 6.

[0024] like Figure 1 , Figure 2As shown, the rotating assembly includes a mounting plate 5, which is fixedly connected to the side wall of the coating box 1. A motor 4 is fixedly connected to the top of the mounting plate 5, and the output shaft of the motor 4 is fixedly connected to the end of one of the rotating rods 6. A transmission wheel 3 is fixedly connected to the outer side wall of both rotating rods 6. The two transmission wheels 3 are connected by a transmission belt 2, and there is friction between the two transmission wheels 3 and the transmission belt 2, thereby realizing transmission. Both transmission wheels 3 are located outside the coating box 1. When the motor 4 is started, the output shaft of the motor 4 drives one of the rotating rods 6 to rotate. This rotating rod 6 drives the other rotating rod 6 to rotate through the transmission wheel 3 and the transmission belt 2, thereby driving the two coating rollers 8 to rotate in the same direction. When the two coating rollers 8 rotate, they can drive the pipe body 10 to rotate. While driving the pipe body 10 to rotate, the two coating rollers 8 can apply anti-corrosion material to the surface of the pipe body 10.

[0025] like Figure 1 As shown, each of the top of the coating box 1 is fixedly connected with a baffle 9. The side wall of each baffle 9 is set parallel to the axis of the coating roller 8. The two baffles 9 can block the anti-corrosion material in the coating box 1 and prevent the two coating rollers 8 from throwing the anti-corrosion material out of the coating box 1.

[0026] like Figure 3 , Figure 4 As shown, a discharge pipe 12 is fixedly connected to the side wall of the coating box 1. The discharge pipe 12 is connected to the inside of the coating box 1, and a sealing cap 11 is threaded to one end of the discharge pipe 12. The inner bottom wall of the coating box 1 is inclined, and the discharge pipe 12 is located at the lowest point of the inclined side wall of the bottom of the coating box 1. When it is necessary to discharge the anti-corrosion material in the coating box 1, the anti-corrosion material flows quickly to the discharge pipe 12, thereby reducing the amount of anti-corrosion material remaining at the bottom of the coating box 1. The inner side walls of the coating box 1 are all provided with an anti-stick coating, which can greatly reduce the adhesion of anti-corrosion material to the inner wall of the coating box 1.

[0027] The working principle of the pipeline anti-corrosion coating device provided by this utility model is as follows: When it is necessary to coat the pipeline body 10 with anti-corrosion material, the anti-corrosion material is poured into the coating box 1, so that the bottom half of the two coating rollers 8 is located in the anti-corrosion material. Then, the pipeline body 10 is placed between the two coating rollers 8. By starting the motor 4, the output shaft of the motor 4 drives one of the rotating rods 6 to rotate. The rotating rod 6 drives the other rotating rod 6 to rotate through the transmission wheel 3 and the transmission belt 2, thereby driving the two coating rollers 8 to rotate in the same direction. When the two coating rollers 8 rotate, they can drive the pipeline body 10 to rotate. While driving the pipeline body 10 to rotate, the two coating rollers 8 can coat the surface of the pipeline body 10 with anti-corrosion material. Since the bottom half of the two coating rollers 8 is located in the anti-corrosion material, the two coating rollers 8 can automatically pick up the material and coat the pipeline body 10 when rotating, so that there is no need to use paint pumps or other electrical components for coating, reducing the production cost of the device. At the same time, the coating area of ​​the pipeline body 10 is large each time, which also reduces the coating time.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
