[0024] 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.
[0025] like Figure 1As shown in Figure 5, this embodiment provides a traction device for power transmission and transformation lines, including a device body 1. The device body 1 is provided with a base 2, a first workbench 17, and a second workbench 18. The bottom of the base 2 is equipped with moving wheels 3 and adjusting legs 4. The base 2 is provided with a mounting frame 5 above the base 2. The mounting frame 5 is provided with a support frame 6. The top of the support frame 6 is connected to a fixing block 7. A threaded rod 8 passes through the fixing block 7. The bottom end of the threaded rod 8 is connected to a connecting plate 9. A spring 10 is provided between the connecting plate 9 and the support frame 6. Adjusting blocks 11 and 22 are slidably connected on the support frame 6. Adjusting blocks 11 are equipped with a first guide wheel 12. Adjusting blocks 23 are equipped with a second guide wheel 14. The second guide wheel 14 is connected to a first motor 15. The mounting frame 5 is also provided with a guide frame 16. The first workbench 17 is provided with a traction shell 19. The second workbench 18 is provided with a second traction shell 20. Both the first traction shell 19 and the second traction shell 20 are provided with a collar 21. A bidirectional screw 22 passes through the collar 21. The bidirectional screw 22 is connected to a second motor 23.
[0026] Preferably, a motor 24 is installed on the second traction housing 20. Traction tracks 28 are provided inside both the first traction housing 19 and the second traction housing 20. The output end of the motor 24 is connected to the first pulley 25. The first pulley 25 is connected to the second pulley 27 through the belt 26. The second pulley 27 and the traction track 28 are in transmission cooperation. Compared with the traditional single roller traction, the track has a large contact area and uniform friction. When tractioning large cross-section, heavy-load power transmission and transformation cables, it is not easy to slip or lose rotation, ensuring traction efficiency and quality. The adjusting leg 4 is a telescopic structure and is equipped with anti-slip pads at the bottom. The moving wheel 3 is a universal wheel with brakes, which allows the device to turn flexibly and move short distances on the construction site. No large handling equipment is required. A single person or a small team can adjust the position of the device to meet the needs of dispersed work sites.
[0027] Preferably, the threaded rod 8 is threadedly engaged with the fixed block 7, and the connecting plate 9 is movably connected with the adjusting block 11 and the adjusting block 2 13 for synchronously adjusting the distance between the guide wheel 12 and the guide wheel 2 14. Construction personnel can finely adjust the distance between the guide wheels by simple rotation operation. Compared with manual disassembly and replacement of parts, the efficiency is increased several times, and the adjustment accuracy is high, meeting the requirements of fine construction. The threads at both ends of the bidirectional screw 22 have opposite directions, and the collar 21 is threadedly engaged with the bidirectional screw 22. Two collars 21 are symmetrically provided, which are respectively connected to the traction shell 19 and the traction shell 20. There is no need for manual disassembly and adjustment of the traction shell position, saving time. It will not shift due to the cable traction force, ensuring the stability of the traction distance during long-term operation and avoiding uneven cable traction force and jamming due to the distance change.
[0028] Preferably, the surface of the traction track 28 is provided with anti-slip texture, and the inner walls of the traction housing 19 and traction housing 20 are adapted to the traction track 28 to increase the friction with the cable surface, prevent slippage that could cause cable sheath wear and traction interruption, ensure construction safety and cable quality, and improve traction stability. The guide frame 16 has a U-shaped structure with wear-resistant pads on its inner wall to provide initial guidance and protection for the cable, provide a precise guiding channel, improve cable threading efficiency, and reduce the time spent on repeated manual adjustments.
[0029] The working principle and process of this utility model are as follows: During use, the device body 1 is supported by the base 2. The movable wheels 3 facilitate the overall transfer of the device to the construction site. The adjustable legs 4 can adjust the device's level and height to adapt to different terrains. The mounting frame 5 provides an installation platform for the upper structure, integrating various functional components. When the cable is being pulled, adjustments are made for adaptation, guidance, and pre-tensioning. On the mounting frame 5, the support frame 6, fixing block 7, threaded rod 8, connecting plate 9, and spring 10 work together. The user can manually rotate the threaded rod 8 to adjust the distance between adjusting block 11, guide wheel 12, adjusting block 213, and guide wheel 214. Motor 15 drives the guide wheels to rotate, and spring 10 provides pre-tensioning force to adapt to cables of different diameters and ensure initial tension during traction. The guide frame 16 assists in the initial guidance of the cable, ensuring accurate entry into the traction mechanism. When cable traction is required, motor 23 starts, driving the bidirectional lead screw 22 to rotate. The collar 21 moves along the bidirectional lead screw 22, adjusting the distance between traction shell 19 and traction shell 20 to adapt to different length traction requirements. Motor 3 24 operates, driving the traction track 28 via pulley 1 25, belt 26, and pulley 27. The friction between the traction track 28 and the cable stabilizes the cable. The traction tracks 28 within traction housings 1 19 and 2 20 work together to grip the cable from different directions, preventing slippage and achieving efficient traction. Worktables 1 17 and 2 18 provide temporary placement and transitional support for the cable. Combined with adjustments to the traction housing spacing, this ensures uniform force on the cable throughout the traction process, improving traction stability and continuity.
