Description
Technical Field
[0001] This utility model relates to the field of traction mechanism technology, and in particular to a traction mechanism for pipeline traction. Background Technology
[0002] Pipeline traction mechanisms are mainly used in pipeline laying, pipeline maintenance, and pipeline production. In pipeline production, traction force is required to drive the pipeline to move. The traction force can be set according to the needs. The traction mechanism is an indispensable piece of equipment in pipeline production.
[0003] A search revealed that among Chinese patents titled "Pipeline Track Tractor Traction Machine," patent number CN219171630U, the background technology states that "during the operation of the traction machine, because the preload of the preload spring changes with the compression length of the spring, when the track slack is large, it is difficult to ensure the track tension, leading to track slippage and other issues, affecting the track's service life, increasing the maintenance cost of the traction machine, and the frequent replacement of the track also affects the production progress and the working efficiency of the traction machine when producing pipelines." The patent further states that "automatic control of the track tension is achieved through the cooperation of a tensioning auxiliary mechanism." The system ensures the normal operation and service life of the traction track, thereby effectively reducing maintenance costs for the traction machine and production costs for the pipeline, further extending the service life of the tracked traction machine. Simultaneously, it corrects and limits the pipeline, ensuring smooth traction and preventing pipeline deviation, thus guaranteeing production progress. While addressing the problems in the background technology, it was found during use that the spacing between the two sets of tracks in the tracked traction machine is difficult to adjust, making it difficult to traction pipelines of different sizes, thus significantly limiting the use of the tracked traction machine.
[0004] Therefore, how to provide a traction mechanism for pipeline traction is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0022] refer to Figure 1-4 In this embodiment, the system includes a housing 1, a fixed track 2, and a movable track 3. A first fixing plate 4 is provided on the side of the fixed track 2 and is fixed to the inner wall of the housing 1. A fixed transmission assembly 5 is provided on the side of the fixed track 2. The fixed transmission assembly 5 includes a first fixing block 10, a first transmission worm gear 11, a first transmission worm 12, and a fixing rod 13. The first fixing block 10 is fixed to the surface of the first fixing plate 4. The first transmission worm 12 is rotatably connected to the first fixing block 10. The first transmission worm gear 11 is fixed to the side of the fixed track 2 and meshes with the first transmission worm 12. The fixing rod 13 is fixed to one end of the first transmission worm 12 near the movable transmission assembly 7. During operation, the rotation of the first transmission worm 12 will drive the first transmission worm gear 11 to rotate, and the rotation of the first transmission worm gear 11 will drive the fixed track 2 to move, thus realizing the rotation of the fixed track 2.
[0023] A second fixing plate 6 is provided on the side of the movable track 3, and a movable transmission assembly 7 is provided on the side of the movable track 3. The movable transmission assembly 7 includes a second fixing block 14, a second transmission worm 15, a second transmission worm wheel 16, and a drive groove 17. The second fixing block 14 is fixed to the surface of the second fixing plate 6. The second transmission worm 15 is rotatably connected to the second fixing block 14. The second transmission worm wheel 16 is provided on the side of the movable track 3, and the second transmission worm 15 meshes with the second transmission worm wheel 16. The drive groove 17 is opened at one end of the second transmission worm 15 near the fixed rod 13. The fixed rod 13 is movably connected inside the drive groove 17. The fixed rod 13 is a square rod, and the drive groove 17 is a square groove whose shape and size match the fixed rod 13. Thus, during adjustment, the second transmission worm... The up-and-down movement of 15 will cause the drive groove 17 to move up and down on the surface of the fixed rod 13. Since the fixed rod 13 is square, when the second transmission worm 15 rotates, it will drive the fixed rod 13 to rotate through the drive groove 17. The rotation of the fixed rod 13 will drive the first transmission worm 12 to rotate. When operating in this position, the second transmission worm 15 will be driven to rotate under the drive of the drive assembly 8. The rotation of the second transmission worm 15 will drive the first transmission worm wheel 11 to rotate. The rotation of the second transmission worm wheel 16 will drive the movable track 3 to move. At this time, the rotation of the second transmission worm 15 will drive the first transmission worm 12 to rotate through the fixed rod 13, achieving the effect of synchronous movement of the fixed track 2. This position operation is before the operation of the fixed transmission assembly 5. The movement of the movable transmission assembly 7 will drive the movement of the fixed transmission assembly 5.
[0024] The movable transmission component 7 is movably connected to the fixed transmission component 5. A drive component 8 is provided at the top of the second fixed plate 6 near the movable transmission component 7. The drive component 8 includes a drive motor 18, a drive gear 19, and a transmission gear 20. The drive motor 18 is fixed to the top of the second fixed plate 6 by a bracket. The drive gear 19 is fixed on the output shaft of the drive motor 18. The transmission gear 20 is fixedly sleeved on the surface of the second transmission worm 15 near the top. The transmission gear 20 and the drive gear 19 mesh with each other. During operation, the drive motor 18 needs to be started. The start of the drive motor 18 will drive the drive gear 19 to rotate. The rotation of the drive gear 19 will drive the transmission gear 20 to rotate. The rotation of the transmission gear 20 will drive the second transmission worm 15 to rotate. Thus, the movement of the movable transmission component 7 is realized through the rotation of the second transmission worm 15.
[0025] The drive assembly 8 is mounted on the movable transmission assembly 7. Adjustment assemblies 9, which drive the movable track 3, are located on the top of the housing 1 and the top of the second fixed plate 6. Each adjustment assembly 9 includes a cross plate 21, a stabilizer frame 22, and an adjustment screw 23. The cross plate 21 is fixed to the top of the housing 1 at its symmetrical axis. The stabilizer frame 22 is fixed to the top of the second fixed plate 6 and is sleeved on the surface of the cross plate 21. The adjustment screw 23 is rotatably connected to the cross plate 21. The other end of the adjustment screw 23 passes through the stabilizer frame 22 and extends above it, so that the stabilizer frame 22 is threaded onto the surface of the adjustment screw 23. The adjustment screw 23 is located at the symmetrical axis of the stabilizer frame 22 and the cross plate. A guide rod 24 is located on the top of the cross plate 21. The top end of the guide rod 24 passes through the stabilizer frame 22 and extends above it. It should be noted that... It is clear that this operation requires the drive assembly 8 to stop. After the drive assembly 8 stops, the adjusting screw 23 is rotated. The rotation of the adjusting screw 23 will cause the stabilizer 22 to move up and down. When the adjusting screw 23 rotates forward, the adjustment screw 23 will cause the stabilizer 22 to move upward. The upward movement of the stabilizer 22 will cause the second fixed plate 6 to move upward. The upward movement of the second fixed plate 6 will synchronously cause the movable track 3 and the movable transmission assembly 7 to move upward. When the movable transmission assembly 7 moves upward, it will cause the second transmission worm gear 15 and the drive groove 17 to move upward. In this way, the distance between the movable track 3 and the fixed track 2 can be adjusted. At the same time, the movable transmission assembly 7 and the fixed transmission assembly 5 can move synchronously through the fixed rod 13, thus achieving the purpose of adjusting the distance between the movable track 3 and the fixed track 2 to match pipes of different sizes.
[0026] 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.
