[0004] In the aforementioned patent, although the problem of lack of support and weak stability in other positions of the pipe is solved by lifting screws and support plates, the process of using gears to drive racks to extend / retract, thereby allowing the support to press against the inner wall of the pipe, lacks automatic clamping or specification adaptation functions. The operation relies on experience, and may require a large amount of manpower for large-diameter pipes, which can easily lead to operator fatigue. Utility Model Content

This process lacks automatic clamping or specification adaptation functions, relies on experience, and may require a large amount of manpower for large-diameter pipes, leading to operator fatigue. Therefore, this invention proposes a surface treatment device for HDPE double-wall corrugated pipes.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Refer to Figures 1-5 As shown: A surface treatment device for HDPE double-wall corrugated pipe includes a drive platform 1, a protective cover 2 installed on one side of the drive platform 1, a grinding disc 3 rotatably connected to one side of the protective cover 2, a support mechanism and a positioning mechanism provided at the bottom of the grinding disc 3, and a telescopic rod 11 connected between the two support mechanisms. The support mechanism includes a motor 16, a support member 18 and a guide frame 19. One side of the motor 16 is fixedly connected to the guide frame 19, the support member 18 is slidably connected to the guide frame 19, an auxiliary member 21 is fixedly connected to one side of the support member 18, a gear 17 is slidably connected to the outer ring surface of the auxiliary member 21, one side of the gear 17 is rotatably connected to the guide frame 19, and a spur gear 20 meshes with one side of the gear 17. The shaft of the spur gear 20 is fixedly connected to the output shaft of the motor 16.

[0025] The telescopic rod 11 passes through the gear plate 17 at both ends and is fixedly connected to the guide frame 19. The gear plate 17 is rotatably connected to the telescopic rod 11, and the inner rod and outer rod of the telescopic rod 11 are slidably connected. A pin is inserted between the inner rod and the outer rod. The support mechanism includes a connecting rod 10, a limiting frame 12, and a guide plate 14. A second motor 15 is fixedly connected to one side of the guide plate 14. A lead screw 13 is fixedly connected to the output shaft of the second motor 15. The lead screw 13 is rotatably connected to the guide plate 14. The lead screw 13 is threadedly connected to the limiting frame 12. One end of the limiting frame 12 is slidably connected to the guide plate 14. A connecting rod 10 is embedded inside the guide plate 14. One end of the connecting rod 10 is fixedly connected to the guide frame 19.

[0026] When the gear plate 17 rotates, it applies a radial force to the auxiliary component 21 that is slidably connected to its outer ring surface, causing the auxiliary component 21 to drive the fixedly connected support component 18 to slide along the guide frame 19. The extension length of the support component 18 is adjusted until the end of the support component 18 is tightly fitted to the inner wall of the pipe, thus completing the pipe support. The telescopic rod 11 passes through the gear plate 17 at both ends and is fixed to the guide frame 19. Its inner rod and outer rod are slidably connected and can be fixed by a pin: on the one hand, it adapts to pipes of different lengths to adjust the distance between the two support mechanisms, and on the other hand, it ensures that the two support mechanisms move synchronously. The lead screw 13 is connected to the limit frame 12 by a thread, and the upper and lower symmetrical limit frames 12 have opposite thread directions: when the lead screw 13 rotates, the two limit frames 12 slide along the guide plate 14 and move closer to the pipe, finally clamping and positioning the end of the pipe. The two positioning mechanisms start synchronously to complete the symmetrical positioning of the two ends of the pipe, providing a stable reference for subsequent grinding. The connecting rod 10 connects the guide frame 19 and the guide plate 14, which not only transmits the position reference of the support mechanism, but also enhances the overall stability of the support mechanism and the positioning mechanism.

[0027] Example 2: Figures 1-3 As shown, one of the connecting rods 10 is rotatably connected to the drive platform 1, and one end of the other connecting rod 10 is inserted with a bevel gear 7. One side of the bevel gear 7 is rotatably connected to an L-shaped frame 4, which is slidably connected to the drive platform 1. The bottom of the bevel gear 7 is meshed with a bevel gear 8, and the shaft of the bevel gear 8 is fixedly connected to the output shaft of a motor 9. The bottom of the motor 9 is fixedly connected to the L-shaped frame 4. A protective plate 5 is provided on one side of the L-shaped frame 4, which is engaged with the drive platform 1 on one side. A collection box 6 is engaged on the top of the protective plate 5, and one side of the collection box 6 is connected to the protective cover 2.

[0028] The L-shaped frame 4 slides on the drive table 1, so that the end of the bevel gear 7 aligns with the connecting rod 10. The connection is then reinforced by bolts. The bevel gear 7 and the connecting rod 10 rotate synchronously, and the connecting rod 10 drives the guide frame 19 to rotate, thereby causing the two support mechanisms and the pipe to rotate synchronously. This, in conjunction with the grinding disc 3, allows for grinding at different positions on the outer ring surface of the pipe, ensuring uniform grinding of the outer ring surface of the pipe by the grinding disc 3 and avoiding excessive grinding or missed grinding in certain areas. The connecting pipe between the protective cover 2 and the collection box 6 is located on the tangent of the grinding disc 3 and is angled upward. During the grinding process, the centrifugal force generated by the high-speed rotation of the grinding disc 3 throws some debris into the pipe along the tangent direction. Finally, the debris falls into the collection box 6 for collection. The protective plate 5, on the one hand, prevents debris from splashing from the side, and on the other hand, provides a locking support for the collection box 6, enhancing the installation stability of the collection box 6. The locking connection between the protective plate 5 and the drive table 1 also facilitates the disassembly and cleaning of the protective plate 5.

[0029] The operating method and working principle of this device are as follows: First, the HDPE double-wall corrugated pipe to be processed is sleeved on the outside of the two support mechanisms. The motor 16 is started using an external controller. Motor 16 drives the spur gear 20 to rotate, which in turn drives the gear disc 17 to rotate. The gear disc 17 applies force to the auxiliary component 21, causing the auxiliary component 21 and the support component 18 to slide along the guide frame 19. The extension length of the support component 18 is adjusted so that the end of the support component 18 fits tightly against the inner wall of the pipe, thus supporting the pipe. Then, the L-shaped frame 4 is moved to one side of the drive platform 1 so that the end of the bevel gear 7 is inserted into the connecting rod 10. Bolts are then installed and fixed at the insertion point. The lead screw 13 is rotated using motor 15, and the components are symmetrically arranged vertically. The limiting brackets 12 have opposite thread directions, which can drive the two limiting brackets 12 to approach the pipe fitting and clamp the end of the pipe fitting. The two positioning mechanisms are activated at the same time to complete the clamping of both ends of the pipe fitting. The surface of the pipe fitting can be polished by the grinding disc 3. During the polishing process, the motor 9 drives the bevel gear 8 to rotate, the bevel gear 8 drives the bevel gear 7 to rotate, the bevel gear 7 and the connecting rod 10 rotate synchronously, and the two support mechanisms rotate synchronously with the pipe fitting under the drive of the connecting rod 10 and the telescopic rod 11. Different positions of the outer ring surface of the pipe fitting can be polished. The pipe connecting the protective cover 2 and the collection box 6 is on the tangent of the grinding disc 3 and the direction is obliquely upward. Some of the debris generated by polishing can be thrown into the collection box 6 through the pipe for collection.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
