Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe installation technology, and in particular to an auxiliary docking device for HDPE corrugated pipe installation. Background Technology

[0002] HDPE double-wall corrugated pipe, or simply PE corrugated pipe, is a new type of lightweight pipe made of high-density polyethylene. It features light weight, high pressure resistance, good toughness, fast construction, and long service life. Currently, in practical applications, the required length of HDPE corrugated pipes often exceeds the manufacturing length of a single pipe. Therefore, auxiliary splicing devices are needed to connect the corrugated pipes to meet the application requirements.

[0003] A search revealed that patent application number 202420652152.9 discloses an auxiliary docking device for corrugated pipe installation, which includes a workbench. A bearing plate is symmetrically arranged on the upper surface of the workbench. Clamping components are fixedly connected to the upper surface of the bearing plate. Sliding rods are symmetrically slidably connected through the bearing plate. Follower frames are fixedly connected between opposite sides of the sliding rods. Limit grooves are opened on the upper surface of the follower frames. Cleaning plates are slidably connected in the limit grooves.

[0004] The aforementioned prior art uses a brush fixedly connected to the opposite side of the cleaning plate, which can effectively remove impurities and foreign objects adhering to the corrugated pipe interface surface, thereby ensuring the cleanliness of the corrugated pipe interface surface for subsequent corrugated pipe docking. However, the clamping components used have a simple structure and poor adjustability, which makes it unable to meet the auxiliary docking requirements of different corrugated pipes. Furthermore, the bearing plate used has a simple structure and lacks an effective pipe tail support structure, which may cause the tail portion of some longer corrugated pipes to be suspended in the air, affecting the stability of the docking process and thus affecting the docking efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary docking device for HDPE corrugated pipe installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary docking device for installing HDPE corrugated pipes includes a support base, a guide rail frame welded to the top outer wall of the support base, and an auxiliary docking mechanism. The auxiliary docking mechanism includes a bidirectional lead screw rotatably installed in the support base, two centering frames symmetrically screwed to the two opposite thread ends of the bidirectional lead screw, a servo drive assembly, and two bearing plates.

[0008] Both of the bearing plates are equipped with pipe clamping components and telescopic tail support components. Both bearing plates are slidably connected to the guide rail frame, and the two centering frames are fixedly connected to the two bearing plates respectively.

[0009] The pipe clamping assembly includes a groove formed on the top of the support plate, a bidirectional screw rotatably installed in the groove, two centering rods symmetrically screwed to the two opposite threaded ends of the bidirectional screw, and two V-shaped positioning blocks symmetrically fixed to the outer wall of the adjacent side of the two centering rods.

[0010] Preferably, the outer walls of both centering rods are slidably connected to the inner wall of the sliding groove, and a handwheel is fixedly connected to the outer wall of one end of the bidirectional screw.

[0011] Preferably, the servo drive assembly includes a fixed cover fixedly connected to the side wall of the support base, a servo motor fixedly installed on one outer wall of the fixed cover, a worm gear fixedly mounted on the output shaft of the servo motor, and a worm wheel fixedly mounted on one end of the bidirectional lead screw.

[0012] Preferably, the output shaft of the servo motor passes through one side of the fixed cover, and the worm and worm wheel mesh with each other and are both located inside the fixed cover.

[0013] Preferably, the telescopic tail support assembly includes a tail support plate aligned with the top of the support plate, two sliding shafts symmetrically welded to the tail support plate, two screw seats symmetrically welded to the side wall of the support plate, and two locking screws sequentially threaded onto the two screw seats.

[0014] Preferably, both sliding shafts have evenly distributed threaded locking holes on their surfaces, the bearing plate has two slide rails, and the outer walls of the two sliding shafts are slidably connected to the inner walls of the two slide rails respectively.

[0015] Preferably, the locking screw is threadedly connected to two of the threaded locking holes.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Equipped with a pipe clamping assembly, which consists of a double-ended screw and two centering rods in a threaded engagement, allowing two V-shaped positioning blocks to move in a centered manner. This facilitates the effective clamping and fixing of HDPE corrugated pipes of different specifications placed on the support plate, thereby effectively improving the adaptability of the clamping assembly and better meeting the auxiliary docking needs of different HDPE corrugated pipes.

[0018] 2. In the docking process, the servo motor drives the worm to rotate, and the worm wheel meshing with the worm will drive the bidirectional lead screw to rotate. Then, the two centering frames will drive the two bearing plates to slide in the center on the guide rail frame. In this way, the precise docking requirement of two HDPE corrugated pipes can be quickly achieved. Moreover, due to the self-locking performance of the worm and worm wheel after meshing, the stability of the docking process of the two HDPE corrugated pipes can be guaranteed, which helps to ensure the docking efficiency of the two HDPE corrugated pipes.

[0019] 3. This utility model, by reasonably adjusting the position of the tail support plate on the support plate, facilitates effective support for the tail ends of HDPE corrugated pipes of different lengths, thereby better ensuring the stability of the HDPE corrugated pipe fixed on the support plate, and further ensuring the docking efficiency of two HDPE corrugated pipes.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1, referring to Figure 1-5 An auxiliary docking device for installing HDPE corrugated pipes includes a support base 1, a guide rail frame 2 welded to the top outer wall of the support base 1, and an auxiliary docking mechanism.

[0029] Specifically, the auxiliary docking mechanism includes a bidirectional lead screw 3 rotatably mounted in the support base 1, two centering frames 4 symmetrically screwed to the two opposite threaded ends of the bidirectional lead screw 3, a servo drive assembly, and two bearing plates 5;

[0030] Furthermore, both bearing plates 5 are equipped with pipe clamping components and telescopic tail support components. Both bearing plates 5 are slidably connected to the guide rail frame 2, and the two centering frames 4 are fixedly connected to the two bearing plates 5 respectively.

[0031] Furthermore, the servo drive assembly includes a fixed cover 10 fixedly connected to the side wall of the support base 1, a servo motor 11 fixedly installed on one outer wall of the fixed cover 10, a worm gear 12 fixedly mounted on the output shaft of the servo motor 11, and a worm wheel 13 fixedly mounted on one end of the bidirectional lead screw 3. The output shaft of the servo motor 11 passes through one side of the fixed cover 10, and the worm gear 12 and the worm wheel 13 mesh with each other and are both located inside the fixed cover 10.

[0032] Furthermore, the pipe clamping assembly includes a groove on the top of the support plate 5, a bidirectional screw 6 rotatably installed in the groove, two centering rods 7 symmetrically screwed to the two opposite threaded ends of the bidirectional screw 6, and two V-shaped positioning blocks 8 symmetrically fixed to the outer wall of the adjacent side of the two centering rods 7. The outer walls of the two centering rods 7 are slidably connected to the inner wall of the groove. A handwheel 9 is fixedly connected to the outer wall of one end of the bidirectional screw 6. When using the pipe clamping assembly, the bidirectional screw 6 is rotated by the handwheel 9. Then, under the limit of the groove, the two centering rods 7 threaded to the bidirectional screw 6 will drive the two V-shaped positioning blocks 8 to center and move closer together. This facilitates the effective clamping and fixing of HDPE corrugated pipes of different specifications placed on the support plate 5, effectively improving the adaptability of the clamping assembly and making it easier to meet the auxiliary docking needs of different HDPE corrugated pipes.

[0033] In this embodiment, the two HDPE corrugated pipes to be connected are first placed on two support plates 5 respectively, and then two pipe clamping assemblies are used to clamp and fix the HDPE corrugated pipes placed on the two support plates 5.

[0034] Secondly, the servo motor 11 drives the worm gear 12 to rotate, and then the worm wheel 13 meshing with the worm gear 12 drives the bidirectional lead screw 3 to rotate. In turn, the two centering frames 4 drive the two bearing plates 5 to slide in center on the guide rail frame 2. This can quickly achieve the requirement of precise docking of two HDPE corrugated pipes. Moreover, due to the self-locking performance of the worm gear 12 and worm wheel 13 after meshing, the stability of the docking process of the two HDPE corrugated pipes can be guaranteed, which helps to ensure the docking efficiency of the two HDPE corrugated pipes.

[0035] Example 2, refer to Figure 4 and Figure 6This embodiment is an optimization based on embodiment 1. Specifically, the telescopic tail support assembly includes a tail support plate 14 aligned with the top of the support plate 5, two sliding shafts 15 symmetrically welded to the tail support plate 14, two screw seats 16 symmetrically welded to the side wall of the support plate 5, and two locking screws 17 sequentially threaded onto the two screw seats 16.

[0036] Furthermore, the surfaces of the two sliding shafts 15 are provided with evenly distributed threaded locking holes 18, and the bearing plate 5 is provided with two slides. The outer walls of the two sliding shafts 15 are slidably connected to the inner walls of the two slides respectively, and the locking screws 17 are threadedly connected to two of the threaded locking holes 18 respectively.

[0037] In this embodiment, by unscrewing the two locking screws 17, the tail support plate 14 can be pulled back to any position. After the position of the tail support plate 14 is adjusted, the two locking screws 17 are threaded into the two threaded locking holes 18 to achieve the locking effect. This operation method allows for flexible adjustment of the position of the two tail support plates 14 on the two support plates 5. By reasonably adjusting the position of the tail support plates 14 on the support plates 5, it is easy to adapt to the effective support of the tail of HDPE corrugated pipes of different lengths, thereby better ensuring the stability of the HDPE corrugated pipes fixed on the support plates 5, which helps to ensure the docking efficiency of the two HDPE corrugated pipes.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
