Description

Technical Field

[0001] This application relates to the field of pipeline processing technology, and in particular to a pipeline pulling mechanism. Background Technology

[0002] Currently, traction mechanisms are devices used during pipeline processing to provide stable tension, helping pipelines maintain the correct orientation, tension, and position during processing, transportation, or installation. Common traction mechanisms include mechanical, hydraulic, and electric traction devices.

[0003] A Chinese patent with publication number CN217226668U discloses a heat shrink tubing pulling device, including a worktable, tubing guide frames on both sides above the worktable, a lower guide wheel and an upper guide wheel mounted on the guide frames, the lower guide wheel being connected to a pulley via a shaft, a drive motor mounted below the worktable, a drive wheel mounted on the output shaft of the drive motor, and the drive wheel being connected to the lower guide wheel via a belt for transmission.

[0004] In related technologies, the device is driven by a motor, and the heat shrink tubing is clamped by the clamping structure of the upper and lower guide wheels, thus completing the pulling operation.

[0005] Regarding the aforementioned technologies, the inventors believe that the traction force of clamping the pipeline with two guide wheels is insufficient. During the pipeline pulling process, relative slippage easily occurs between the pipeline and the guide wheels, which in turn affects the pipeline processing efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a pipeline pulling mechanism, which solves the technical problem that the traction force of the two guide wheels clamping the pipeline forward is insufficient, and that the pipeline and the guide wheels are prone to relative slippage during the pipeline pulling process, thus affecting the pipeline processing efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A pipeline pulling mechanism includes: a frame for supporting the pulling mechanism; a slider slidably mounted on the frame; a clamping assembly mounted on the slider for clamping the pipeline; and a driving assembly mounted on the frame for driving the slider to slide on the frame.

[0009] Furthermore, the clamping assembly includes a clamping cylinder mounted on the slider; a lower pressing block is provided on the slider, and an upper pressing block is provided on the clamping cylinder. The lower pressing block and the upper pressing block are arranged opposite to each other. A lower pressing groove is formed on the lower pressing block, and an upper pressing groove is formed on the upper pressing block.

[0010] Furthermore, a support spring is provided on the upper pressure block, with one end of the support spring connected to the upper pressure block and the other end facing the side closer to the lower pressure block.

[0011] Furthermore, the drive assembly includes a drive motor and a screw. The drive motor is mounted on the frame, the screw is rotatably mounted on the frame, and one end of the screw is connected to the drive motor. The screw passes through the slider, and the slider is threadedly connected to the screw.

[0012] Furthermore, a guide block is provided on one side of the slider, the guide block is slidably mounted on the frame, and a guide hole is provided on the guide block, the axis of the guide hole being parallel to the axis of the screw.

[0013] Furthermore, the drive motor is provided with a guide rod, one end of which is connected to the drive motor, and the other end passes through the slider and is connected to the guide block.

[0014] Furthermore, a support pad is provided on the side of the guide block opposite to the slider, and the support pad is installed on the slider.

[0015] In summary, this application includes at least one of the following pipeline pulling mechanisms, which offer the following beneficial technical effects:

[0016] 1. During use, the pipeline passes through the slider of the frame, the clamping assembly clamps the pipeline, and then the drive assembly drives the slider to slide on the frame. As the slider slides on the frame, the pipeline is pulled on the frame. By clamping the pipeline before pulling, a larger traction force can be provided to prevent the pipeline from sliding relative to each other during the pulling process, thereby improving the processing efficiency of the pipeline.

[0017] 2. The upper and lower pressure blocks on the clamping cylinder and slider, as well as the support spring on the upper pressure block, improve the stability of the clamping pipeline between the upper and lower pressure blocks.

[0018] 3. The stability of the slider during the sliding process is improved by setting up guide blocks, guide rods and support pads. Attached Figure Description

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses a pipeline pulling mechanism.

[0026] Reference Figure 1 A pipeline pulling mechanism includes a frame 1, a slider 2 is provided on the frame 1, a clamping assembly 3 is provided on the slider 2, the clamping assembly 3 is used to clamp the pipeline, and a driving assembly 4 is provided on the frame 1, the driving assembly 4 is used to drive the slider 2 to slide on the frame 1.

[0027] Reference Figures 2-3 The clamping assembly 3 includes a clamping cylinder 31, which is mounted on the slider 2, with the piston rod of the clamping cylinder 31 facing towards the side closer to the slider 2. A lower pressure block 32 is mounted on the side of the slider 2 near the clamping cylinder 31, and an upper pressure block 33 is mounted on the piston rod of the clamping cylinder 31. The lower pressure block 32 and the upper pressure block 33 are arranged opposite to each other. In addition, a lower pressure groove 321 is formed on the lower pressure block 32, and an upper pressure groove 331 is formed on the upper pressure block 33. When the upper pressure block 33 presses against the lower pressure block 32, the cross-section formed by the upper pressure groove 331 and the lower pressure groove 321 is circular. In use, the pipeline passes between the lower pressure block 32 and the upper pressure block 33, and then the lower pressure block 32 and the upper pressure block 33 clamp the pipeline.

[0028] Reference Figure 3 To improve the ease of pipeline insertion between the lower pressure block 32 and the upper pressure block 33, guide slopes 34 are formed on both sides of the lower pressure block 32 and the upper pressure block 33. The guide slopes 34 are inclined towards the inner side of the lower pressure groove 321 and the upper pressure groove 331. The pipeline is guided by the guide slopes 34, which improves the ease of pipeline insertion between the lower pressure block 32 and the upper pressure block 33.

[0029] Furthermore, rubber pads 35 are provided on the sides of the lower pressure block 32 and the upper pressure block 33 that are close to each other. The rubber pads 35 are embedded inside the lower pressure grooves 321 and the upper pressure grooves 331 of the lower pressure block 32 and the upper pressure block 33, respectively. When the lower pressure block 32 and the upper pressure block 33 clamp the pipeline, the rubber pads 35 are pressed against the pipeline and the corresponding lower pressure block 32 and upper pressure block 33. On the one hand, the rubber pads 35 can protect the surface of the pipeline and prevent the lower pressure block 32 and the upper pressure block 33 from scratching the pipeline. On the other hand, the rubber pads 35 can increase the friction between the pipeline and the lower pressure block 32 and the upper pressure block 33, thereby improving the stability of the pipeline pulling.

[0030] In addition, a support spring 36 is provided on the upper pressure block 33. One end of the support spring 36 is connected to the upper pressure block 33, and the other end faces the side closer to the lower pressure block 32. When the upper pressure block 33 moves to the side closer to the lower pressure block 32, the support spring 36 is in a compressed state, thereby reducing the impact force of the upper pressure block 33 pressing against the lower pressure block 32.

[0031] A slide rail 11 is provided on the frame 1. The slide rail 11 is mounted on the frame 1. A first support block 12 is provided on the slide rail 11. The first support block 12 is slidably mounted on the slide rail 11, and the slider 2 is mounted on the first support block 12. When in use, the slider 2 slides on the slide rail 11 through the first support block 12.

[0032] To improve the ease of sliding the slider 2 on the slide rail 11, the drive assembly 4 includes a drive motor 41 and a screw 42. The drive motor 41 is mounted on the frame 1, and the screw 42 is rotatably mounted on the frame 1. One end of the screw 42 is connected to the output shaft of the drive motor 41, and the other end of the screw 42 passes through the slider 2, with the slider 2 and the screw 42 threadedly connected. In use, the drive motor 41 drives the screw 42 to rotate forward or backward. As the screw 42 rotates, the slider 2 reciprocates along the slide rail 11. When the slider 2 slides away from the drive motor 41, the lower pressure block 32 and the upper pressure block 33 clamp the pipeline. When the slider 2 slides closer to the drive motor 41, the upper pressure block 33 moves away from the drive motor 41. This reciprocating motion allows the pipeline to be pulled.

[0033] Reference Figure 2 To improve the stability of the pipeline during the pulling process, a second support block 21 and a guide block 22 are provided on the side of the slider 2 away from the drive motor 41. The second support block 21 is slidably mounted on the slide rail 11, and the guide block 22 is mounted on the second support block 21. Furthermore, a guide hole 23 is formed on the guide block 22, and the axis of the guide hole 23 is parallel to the axis of the screw 42. When the pipeline passes through the space between the lower pressure block 32 and the upper pressure block 33, one end of the pipeline passes through the guide hole 23 on the guide block 22. The guide block 22 guides the pipeline, thereby improving the stability of the pipeline during the pulling process.

[0034] Furthermore, the drive motor 41 is equipped with guide rods 24. Two guide rods 24 are spaced apart on both sides of the screw 42, and the two guide rods 24 are parallel to and spaced apart from the screw 42. In use, one end of the guide rod 24 is telescopically mounted on the drive motor 41, and the other end passes through the slider 2 and connects to the guide block 22. During use, the guide rod 24 guides the slider 2, thereby improving the stability of the slider 2 moving on the slide rail 11.

[0035] Furthermore, a support pad 25 is provided on the side of the guide block 22 away from the slider 2. The support pad 25 is mounted on the guide block 22 and is made of rubber. When the slider 2 moves away from the drive motor 41, the support pad 25 contacts the frame 1. Since the support pad 25 is made of rubber, it can reduce the impact generated by the slider 2 during movement, thereby improving the stability of the slider 2 during movement.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
