Description

Technical Field

[0001] This invention relates to the field of exhaust pipe cleaning technology, and more particularly to an exhaust pipe pre-coating cleaning device. Background Technology

[0002] The exhaust pipe plays a crucial role in expelling combustion gases during vehicle operation. During use, the inner wall of the exhaust pipe is constantly exposed to high temperatures, high pressures, and exhaust gases containing various chemical components. Consequently, the outer surface of the exhaust pipe accumulates a significant amount of dust, sediment, and other particulate matter. Therefore, a coating is necessary for the outer surface of the exhaust pipe. Before applying the coating, thorough cleaning is required to ensure good adhesion between the coating and the exhaust pipe surface, thereby improving the coating's quality and durability.

[0003] Patent CN221817079U discloses a truck exhaust pipe cleaning device. This device uses an exhaust pipe inner wall cleaning structure to clean urea crystals adhering to the inner wall of the truck exhaust pipe. The exhaust pipe inner wall cleaning structure is placed inside the truck exhaust pipe. When the rotating device drives the exhaust pipe inner wall cleaning structure to rotate, centrifugal force is generated, which stretches the spring rod and causes the rotating rod to rotate outward. This causes the cleaning block at one end of the rotating rod to fit against the inner wall of the truck exhaust pipe, thereby cleaning the urea crystals adhering to the inner wall of the truck exhaust pipe.

[0004] The device cleans by using centrifugal force generated when the inner wall cleaning structure rotates. However, there may be deposits on the exhaust pipe. Some deposits are tightly connected to the exhaust pipe and are difficult to separate by centrifugal force alone. If the deposits are not thoroughly cleaned during the exhaust pipe cleaning process, it will affect the quality of the coating. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a device for clamping and rotating the exhaust pipe, which can simultaneously clean the inner wall and outer surface of the exhaust pipe, and can also be dried after cleaning.

[0026] See Figure 1-5 As shown, the present invention provides a pre-coating cleaning device for an exhaust pipe, including a base plate 11, a track 12 on the base plate 11, a positioning and rotating device on the track 12, the positioning and rotating device being used to position the exhaust pipe and rotate the exhaust pipe, the positioning and rotating device being able to move horizontally on the track 12, and a cleaning device being provided at one end of the base plate 11, the cleaning device being able to clean the inner and outer walls of the exhaust pipe and dry the exhaust pipe.

[0027] The aforementioned base plate 11 has a rectangular structure and is located at the bottom of the entire device. Two linear tracks 12 are provided on the base plate 11, which extend along the length of the base plate 11. Each of the two tracks 12 is equipped with a slider 13 that matches the track 12. The slider 13 can slide horizontally on the track 12. A placement plate 14 is fixedly connected to the two sliders 13. The placement plate 14 can move horizontally on the track 12. A positioning and rotating device is installed on the placement plate 14.

[0028] The positioning and rotating device includes a rotating disk 21, which is a circular disk structure. There is a through hole at the center of the rotating disk 21, through which the exhaust pipe can pass. A fixed disk 22 is connected to the rotating disk 21 and is fixedly connected to the placement plate 14. The external dimensions of the fixed disk 22 are the same as those of the rotating disk 21. Several straight grooves 23 are provided on the fixed disk 22, which extend from the edge of the fixed disk 22 towards the center. The sliding grooves 23 are arranged in a circular array on the surface of the fixed disk 22. Several arc-shaped slots 24 are arranged in a circular array on the surface of the rotating disk 21, extending from the edge to the center. Several connecting blocks 25 are mounted on the rotating disk 21 and are installed within the sliding grooves 23. Each connecting block 25 has a cylindrical platform 26 on its bottom surface, which is engaged within the slot 24 and can move along it. A chuck 27 is mounted on each connecting block 25 and can move towards the center or towards the edge along the sliding grooves 23 on the fixed disk 22. A drive motor 15 is connected to the rear end of the rotating disk 21, providing driving force for the rotation of the rotating disk 21.

[0029] When the rotating disk 21 rotates, the cylindrical platform 26 on the bottom surface of the connecting block 25 is engaged in the slot 24 of the rotating disk 21, while the connecting block 25 is installed in the linear slide groove 23 of the fixed disk 22. As the rotating disk 21 rotates, the slot 24 causes the cylindrical platform 26 to move the connecting block 25 and the chuck 27 along the slide groove 23. When the chuck 27 moves towards the center, it can position the exhaust pipe passing through the central through hole of the rotating disk 21. After positioning, the rotating disk 21 continues to rotate, and the chuck 27 will continuously apply clamping force to the exhaust pipe and drive the exhaust pipe to rotate.
