[0003] In the prior art, after the pipe welding is completed, the pipe needs to be pulled by the continuous rotation of the V-shaped roller. Specifically, during the welding process, when a certain section of the pipe has been welded, the V-shaped roller will smoothly push the pipe forward to ensure that it smoothly enters the next processing procedure.

[0004] However, the above-mentioned pulling method still has defects.

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a pipe traction device for a gantry-type high-frequency welded pipe equipment, comprising: a fixed frame 1, which provides fixed support for the entire device to ensure stability during pipe traction; a threaded rod 2 is rotatably sleeved inside the fixed frame 1; a connecting sleeve 3 is threaded onto the threaded rod 2; the thread on the inner ring of the connecting sleeve 3 is adapted to the threaded rod 2; the bottom of the connecting sleeve 3 is welded and fixed to a traction block 4; a T-shaped frame 5 is fixedly connected to the bottom of the traction block 4; the connecting sleeve 3, the traction block 4, and the T-shaped frame 5 are fixedly connected; support blocks 6 are fixedly connected to both sides of the bottom of the T-shaped frame 5; a fixed clamping plate 7 is installed on one side of the bottom of the support block 6; and a movable clamping plate 8 is slidably installed on the other side of the bottom of the support block 6; the bottoms of the fixed clamping plate 7 and the movable clamping plate 8 are arc-shaped to facilitate pipe clamping.

[0025] The fixed frame 1 is fixed at the discharge end of the gantry-type high-frequency welded pipe equipment. When the pipe needs to be pulled, the connecting sleeve 3 moves along its axis by rotating the drive threaded rod 2, which drives the traction block 4 and T-shaped frame 5 to perform linear reciprocating motion, thereby driving the support block 6 to move synchronously, which facilitates the effective pulling of the pipe. After a section of the pipe has been welded, the clamping plate 8 is moved towards the fixed clamping plate 7 to clamp the pipe, and then the traction block 4 pulls it. This design avoids the slippage phenomenon that may occur when the traditional V-shaped roller handles large-diameter or long-distance pipes, ensures stable traction force output, and significantly improves the conveying speed and production efficiency.

[0026] Example 2: Based on Example 1, fixed rods 9 are fixedly connected to the four corners of the bottom of the fixed frame 1. Bearings 10 are fixedly installed inside the two side walls of the fixed frame 1. The threaded rod 2 is rotatably sleeved in the bearings 10 on both sides and fixedly connected to the ground through the fixed rods 9, so that the fixed rods 9 provide fixed support for the fixed frame 1 and ensure stability during traction. The bearings 10 installed on the side wall of the fixed frame 1 improve the rotational stability of the threaded rod 2 and further improve the stability during traction. One end of the threaded rod 2 is fixedly connected to the output end of the drive motor 11. The drive motor 11 is fixedly installed on the outer wall of one side of the fixed frame 1 and electrically connected to the external terminal control equipment. A sliding hole 12 is opened on the traction block 4. The sliding hole 12 limits the limit rod 13. The limit rod 13 is slidably sleeved in the sliding hole 12. Both ends of the limit rod 13 are fixedly connected to the inner wall of the fixed frame 1.

[0027] After the fixed clamping plate 7 and the movable clamping plate 8 clamp and fix the pipe, the drive motor 11 is started by the external control device. The drive motor 11 drives the threaded rod 2 to rotate. Under the action of the rotation of the threaded rod 2, the connecting sleeve 3 is threadedly connected to the threaded rod 2, thereby causing the connecting sleeve 3 to drive the traction block 4 to move. The traction block 4 then drives the T-shaped frame 5 and the support block 6 to move synchronously along the axis of the threaded rod 2. At the same time, the traction block 4 is limited by the limit rod 13 and the sliding hole 12, which not only enhances the guiding accuracy of the traction block 4, but also prevents lateral swaying, further improving the stability of the traction process. The further beneficial effects are improved automation, accurate positioning and anti-deviation, and extended equipment life.

[0028] Example 3: Based on Example 2, one side of the support block 6 is fixedly connected to the T-shaped frame 5, and a synchronous controller 14 and a clamping motor 15 are fixedly installed on the other side of the support block 6. The synchronous controller 14 and the clamping motor 15 are electrically connected. Through the setting of the synchronous controller 14, the two clamping motors 15 can be controlled to rotate synchronously. A limit groove 16 is opened at the bottom of the support block 6. The limit groove 16 is slidably connected to the upper side of the U-shaped toothed plate 17. One end of the lower side of the U-shaped toothed plate 17 is fixedly connected to the top of the movable clamping plate 8. Next, the bottom ends of the fixed clamping plate 7 and the movable clamping plate 8 are fixedly connected with anti-slip pads 21, which are made of high-temperature resistant rubber. The output end of the clamping motor 15 is fixedly connected to one end of the connecting shaft 18, and the other end of the connecting shaft 18 is rotatably sleeved in the connecting ear 19. The connecting ear 19 improves the stability of the connecting shaft 18 during rotation. The top of the connecting ear 19 is fixedly connected to the support block 6. The outer ring surface of the connecting shaft 18 is fixedly sleeved with a toothed column 20, and the upper side of the toothed column 20 meshes with the U-shaped toothed plate 17 for transmission.

[0029] When the traction block 4 moves to the preset position at the outlet of the high-frequency welded pipe equipment, the clamping motor 15 is started by the synchronous controller 14. The clamping motor 15 drives the connecting shaft 18, which is fixedly connected to its output end, to rotate under the limit of the connecting ear 19. The connecting shaft 18 then drives the toothed column 20 to rotate. The toothed column 20 then meshes with the U-shaped toothed plate 17, causing the U-shaped toothed plate 17 to drive the movable clamping plate 8, which is fixedly connected to it, to move closer to the fixed clamping plate 7 until the pipe is clamped and fixed between the movable clamping plate 8 and the fixed clamping plate 7. At the same time, the anti-slip pad 21 effectively prevents the pipe from sliding during the traction process, avoiding the slippage phenomenon that may occur when the traditional V-shaped roller handles large-diameter or long-distance pipes. This device can maintain stable and reliable clamping and traction capabilities under various complex working conditions, meeting the needs of different industries. In addition, different pipe diameters can be clamped and pulled by controlling the distance between the movable clamping plate 8 and the fixed clamping plate 7, improving the practicality of the entire device.

[0030] In actual use, the fixed rod 9 is fixedly connected to the ground, thereby providing fixed support for the fixed frame 1 and ensuring stability during traction. When the traction block 4 moves to the preset position of the high-frequency welded pipe equipment pipeline outlet, the clamping motor 15 is started by the synchronous controller 14. The clamping motor 15 drives the connecting shaft 18 fixedly connected to its output end to rotate under the limit of the connecting ear 19. The connecting shaft 18 then drives the toothed column 20 to rotate, and the toothed column 20 then meshes with the U-shaped toothed plate 17, causing the U-shaped toothed plate 17 to drive the movable clamping plate 8 fixedly connected to it to move towards the ground. The pipe moves towards the fixed clamping plate 7 until it is clamped and fixed between the movable clamping plate 8 and the fixed clamping plate 7. After the fixed clamping plate 7 and the movable clamping plate 8 clamp and fix the pipe, the drive motor 11 is started by the external control device. The drive motor 11 drives the threaded rod 2 to rotate. Under the action of the rotation of the threaded rod 2, the connecting sleeve 3 is threadedly connected to the threaded rod 2, thereby causing the connecting sleeve 3 to drive the traction block 4 to move. The traction block 4 then drives the T-shaped frame 5 and the support block 6 to move synchronously along the axis of the threaded rod 2, thereby realizing the traction of the pipe.
