[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The track-type conveyor system for electrophoretic coating is the core conveying system in a modern electrophoretic coating production line, primarily responsible for the automatic transfer of workpieces during the coating process. It typically employs a robust suspended conveyor chain structure, consisting of a drive unit, tensioning device, track (I-beams or enclosed track), carrying trolley, lifting devices, and a sophisticated electrical control system (such as a PLC), forming a highly efficient, continuous closed-loop conveying network. In the pretreatment process, it can send workpieces into tanks for degreasing, washing, surface conditioning, phosphating (or other conversion coating treatments) for surface cleaning and pretreatment. The inventors discovered that these tanks are generally arranged at equal intervals, while track-type conveyors typically lift automotive parts suspended on lifting beams as a whole, and each lifting trolley on the production line only lifts one lifting beam, resulting in low conveying efficiency.

[0021] In some embodiments, please refer to the accompanying drawings. Figure 1 A track-type conveying equipment for electrophoretic coating of automotive parts that is easy to clean includes a displacement part 10 and a hanging part 20 installed on the displacement part 10. The displacement part 10 is a moving part of the device, which drives the hanging part 20 to move left and right. The hanging part 20 is a functional part of the device that lifts the lifting beam 30. Specifically, such as Figure 1 As shown, the displacement part 10 includes a steel rail 11, which serves as a support track for the movement of the mobile trolley on the production line. In this embodiment, the mobile trolley includes a mobile frame 12 that can move left and right on the steel rail 11, and a winch 13 mounted on the mobile frame 12. A lifting rope 131 is mounted on the winch 13, and the other end of the lifting rope 131 passes over a fixed pulley 132 fixed in the middle of the mobile frame 12 and is then fixed downwards to the lifting frame 15. The above part is the functional part of the mobile trolley in the prior art. When the winch 13 is working, it winds up the lifting rope 131, which drives the lifting frame 15 to move upwards. The movement of the mobile frame 12 on the steel rail 11 and the working principle of the winch 13 are prior art and will not be described in detail here. In addition, the shape of the lifting frame 15 is as follows: Figure 1 As shown, it is a rectangular frame structure, with a tie rod 212 vertically threaded at each of the four corners at the bottom. Both ends of the tie rod 212 are threaded. In addition, a vertical guide rail 14 is fixedly installed on the side wall of the movable frame 12. The guide rail 14 has a limiting groove for limiting the pulleys on the hoisting frame 15, so that the hoisting frame 15 is slidably connected to the guide rail 14. Under the constraint of the guide rail 14, the hoisting frame 15 moves up and down more smoothly. On the other hand, such as Figure 2As shown, the hanging part 20 includes a hanging plate 21, which is elongated and made of channel steel. Its cross-section is an inverted C-shape, and its interior is a cavity for accommodating the telescopic plate 22. A connecting plate 211 is welded to the upper end of the hanging plate 21. A threaded hole is formed on the connecting plate 211 that matches the threaded end of the pull rod 212. The lower end of the pull rod 212 is threaded onto the connecting plate 211. The telescopic plate 22 has an inverted convex cross-section and fits into the cavity of the telescopic plate 22. The surface of the telescopic plate 22 is smooth, and lubricating oil is applied between it and the inner wall of the hanging plate 21 to ensure smooth sliding between them. Furthermore, as... Figure 3 , Figure 4 As shown, a motor 221 is fixedly installed in the cavity of the mounting plate 21. The shaft of the motor 221 is fixedly connected to one end of the threaded rod 222. Correspondingly, a threaded hole adapted to the threaded rod 222 is installed axially at the end of the telescopic plate 22. The two are threadedly connected. When the motor 221 drives the threaded rod 222 to rotate, the threaded rod 222 can push the telescopic plate 22 to extend and retract from the cavity of the mounting plate 21. Figure 3 As shown, the above-mentioned parts are arranged symmetrically in two sets on the left and right sides of the hanging plate 21. When the telescopic plate 22 extends out of the hanging plate 21, the overall length of the hanging plate 21 and the telescopic plate 22 increases. Therefore, more hanging beams 30 can be suspended on the hanging plate 21 and the telescopic plate 22. The shape of the hanging beams 30 is as follows: Figure 3 As shown, the upper part is a hook 31 that hangs on the edge of the hanging plate 21 and the telescopic plate 22, and the lower part is an I-beam, with the semi-finished automotive parts to be processed suspended at the lower end of the I-beam. In use, the moving frame 12 first stops at a specific position on the rail 11, and pretreatment troughs are placed at equal intervals on the ground directly below the rail 11. Then, the winch 13 lowers the hoisting frame 15 so that the hanging plate 21 is at a height corresponding to the hook 31 on the lifting beam 30. At this time, the lower end of the lifting beam 30 is suspended from the automotive parts, which are placed in the processing trough for surface treatment. Finally, driven by the motor 221, the telescopic plate 22 extends from the hanging plate 21 to lift the lifting beam 30 and the automotive parts on it in two consecutive troughs and transfer them to the adjacent process trough. When the device only needs to lift one lifting beam 30, the telescopic plate 22 is retracted into the hanging plate 21 in the reverse process described above.

[0022] By setting up extendable telescopic plates 22 and other related components, the device can simultaneously lift multiple lifting beams 30. Compared with existing fixed components, the working efficiency is higher. At the same time, the displacement part 10 can drive the hanging part 20 from the working area to the stopping area on the rail 11. In the stopping area, the hanging part 20 can be moved downwards, which is convenient for staff to maintain and clean.

[0023] In some embodiments, a ring of cleaning cotton is glued and fixed at the port of the hanging plate 21. At this time, the telescopic plate 22 is smaller than the hanging plate 21. Both the telescopic plate 22 and the hanging plate 21 are made of steel. The surface of the telescopic plate 22 and the inner wall of the hanging plate 21 are polished smooth. In the long axis direction, the telescopic plate 22 can slide into the cavity of the hanging plate 21. When the telescopic plate 22 and the hanging plate 21 slide relative to each other, the cleaning cotton that is in contact with the outer surface of the telescopic plate 22 slides relative to the surface of the telescopic plate 22.

[0024] By setting up cleaning cotton, the surface of the telescopic plate 22 is self-cleaned during the telescopic operation, thereby reducing the difficulty of cleaning and maintaining this part of the device for workers.

[0025] Working principle: First, the moving frame 12 stops at a specific position on the rail 11. Pre-treatment troughs are placed at equal intervals on the ground directly below the rail 11. Then, the winch 13 lowers the hoisting frame 15 so that the hanging plate 21 is at the height corresponding to the hook 31 on the lifting beam 30. At this time, the lower end of the lifting beam 30 is suspended from the automotive parts. The automotive parts are in the processing trough for surface treatment. Finally, driven by the motor 221, the telescopic plate 22 extends from the hanging plate 21, lifting the lifting beam 30 and the automotive parts on it in two consecutive troughs and transferring them to the adjacent process trough.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
