[0002] When producing or laying wires and cables, they need to be pulled out from the reels and sent to the workstations or threaded into relevant pipelines.

[0003] For example, the announcement number "CN207303844U" discloses a traction device for power cables, including a base, an electric lifting frame, a winding rod and a servo motor, characterized in that: a walking wheel is installed at the bottom of the base, a placement groove is provided in the base, and a battery is installed in the placement groove, two sets of mounting seats are installed on the top of the base through the electric lifting frame, the side wall of the mounting seat is installed with a mounting chamber through mounting bolts, a servo motor is installed in the mounting chamber, and a reducer is provided on the servo motor, and an axis rod passing through the winding rod is installed at the output end of the servo motor, and circular limit plates are installed at both ends of the winding rod. During operation, although the cable can be stretched and pulled by the servo motor, the traditional manual pulling is eliminated, saving manpower. However, during the traction and release process, it is very easy for the cable to shake violently, thereby affecting the traction operation. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a simple wire clamping and traction mechanism with reasonable structural design and good traction effect.

The incoming wire guide roller group, the rear traction wheel group, the front traction wheel group and the outgoing wire guide roller group are arranged in sequence on the frame, the driving motor is arranged at the bottom of the frame, and drives the front traction wheel group and the rear traction wheel group to rotate through the synchronous transmission assembly.

[0006] As a preferred solution of the present invention, the front traction wheel group includes a base, a polished rod, a top plate, a slide, a linear drive device, an upper rubber-coated drum, and a lower rubber-coated drum. The roller of the lower rubber-coated drum is arranged on the base through a bearing, the polished rod is vertically arranged on the base, the top plate is fixed to the upper end of the polished rod, the slide is movably arranged on the polished rod, the roller of the upper rubber-coated drum is arranged on the slide through a bearing, and the linear drive device is arranged on the top plate and can drive the slide to move up and down. The lifting and lowering of the upper rubber-coated drum is controlled by the telescopic action of the linear drive device, thereby adapting to cables of different diameters and adjusting different downward pressures.

[0007] As a preferred solution of the present invention, the base includes two lower bearing seats that are relatively spaced apart, which has a simple structure and is easy to implement.

[0008] As a preferred solution of the present invention, the slide includes a push plate and two upper bearing seats relatively spaced apart at both ends of the push plate. The structure has good stability, so that the upper rubber-coated roller can be stably mounted on the slide, and can realize lifting and lowering actions under the drive of the linear drive device, further improving the accuracy and stability of cable clamping.

[0009] As a preferred solution of the present invention, the linear drive device is an air cylinder, an oil cylinder or a linear motor, which can meet the usage requirements in different scenarios.

[0010] As a preferred solution of the present invention, the rear traction wheel set has the same structure as the front traction wheel set, which simplifies the production process, reduces manufacturing costs, and is also convenient for later maintenance.

[0011] As a preferred solution of the present invention, the incoming wire guide roller group includes a bracket, a horizontal adjustment plate, a horizontal roller and a vertical roller. The horizontal roller is horizontally arranged on the bracket, and the horizontal adjustment plate is provided with a long hole extending along its long side. Two vertical rollers are arranged side by side on the long hole, so that the cable can maintain the correct posture before entering the traction mechanism, thereby ensuring the traction effect.

[0012] As a preferred solution of the present invention, the structure of the outgoing wire guide roller group is consistent with that of the incoming wire guide roller group, which simplifies the design of the mechanism.

[0013] As a preferred solution of the present invention, the synchronous transmission assembly includes a driving pulley, a driven pulley and a synchronous belt. The two driven pulleys are respectively arranged on the front traction wheel group and the rear traction wheel group. The driving pulley is arranged on the rotating shaft of the drive motor. The synchronous belt is wound around the driving pulley and the two driven pulleys to achieve synchronous drive of the front traction wheel group and the rear traction wheel group, thereby ensuring the synchronization and coordination of the cables during the traction process.

[0014] As a preferred solution of the present invention, a horizontal support plate is provided between the front and rear traction wheel groups. This supports the cable, stabilizes its posture during transmission, and prevents it from sagging or twisting due to its own weight or external forces, thereby improving the accuracy and stability of cable traction.

[0015] The beneficial effects of the utility model are as follows: the structural design of the utility model is reasonable, and the cable is pulled and transported by synchronous operation of the front and rear traction wheel groups, which can keep the cable pulled stably, and avoid shaking during the cable traction and transportation that affects the traction operation. At the same time, combined with the setting of the incoming wire guide roller group and the outgoing wire guide roller group, not only can the deviation of the cable be reduced during the traction process, but also the versatility and flexibility of the mechanism are improved, and the traction use requirements in a wide range of angles can be met.

The polished rod 22 is vertically mounted on the base 21. The top plate 23 is fixed to the upper end of the polished rod 22. The slide 24 is movably mounted on the polished rod 22. Specifically, the slide 24 includes a push plate and two upper bearing seats spaced apart from each other at the push plate. The ends of the roller shaft of the upper rubber-coated roller 26 are each mounted on the upper bearing seats via a bearing. The linear drive 25 is mounted on the top plate 23 and can drive the slide 24 to move up and down. The telescopic movement of the linear drive 25 controls the lifting and lowering of the upper rubber-coated roller 26, thereby accommodating cables of different diameters and adjusting different downward pressure levels. In this embodiment, the linear drive device 25 is a pneumatic cylinder, and a manual valve is provided on the top plate 23 for controlling the cylinder's operating state. In other embodiments, the linear drive device 25 can also be an oil cylinder or a linear motor to meet the needs of different scenarios. Preferably, a horizontal support plate 8 is provided between the front traction wheel assembly 2 and the rear traction wheel assembly 3. This supports the cable and stabilizes its posture during transmission, preventing it from sagging or twisting due to its own weight or external forces, thereby improving the accuracy and stability of cable traction.

[0024] See also Figure 4 The incoming wire guide roller group 4 includes a bracket 41, a horizontal adjustment plate 42, a horizontal roller 43 and a vertical roller 44. The horizontal roller 43 is horizontally arranged on the bracket 41. The horizontal adjustment plate 42 is provided with a long hole extending along its long side. Two vertical rollers 44 are arranged side by side on the long hole.
