[0002] A cable is an electrical cable used to transmit power, signals, or data. It is usually composed of a conductor (such as copper or aluminum) and an insulating material. For communication and data cables, appropriate tension helps maintain signal stability and transmission quality. This process requires the use of a tension adjustment device. The main function of this device is to keep the cable tension within a set range to prevent problems caused by excessive or insufficient tension.

[0003] Traditional cable tension adjustment devices typically use electric and hydraulic tension adjustment mechanisms. Electric and hydraulic tension adjustment mechanisms utilize an electric motor to drive the adjustment mechanism, achieving precise tension adjustment through an electronic control system. Hydraulic systems provide precise tension adjustment and are suitable for applications requiring a certain degree of flexibility and automatic adjustment. Hydraulic pumps and valves control the flow of fluid in the hydraulic cylinder to adjust cable tension.

[0004] However, traditional electronic control systems and hydraulic systems often require complex hydraulic pipelines or electrical control systems, which are difficult to maintain and are prone to problems such as liquid leakage, oil contamination, and electrical failures. When adjusting cable tension, maintenance efficiency is low and maintenance costs are high. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a cable tension adjustment device, which aims to improve the problems of liquid leakage, oil pollution and electrical failure often existing in traditional tension adjustment structures, and the problems of low maintenance efficiency and high maintenance cost when adjusting cable tension.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a cable tension adjustment device, including a fixed platform 1, a support platform 2 is fixedly connected to the top of the fixed platform 1, and a plurality of turntables 3 are fixedly connected to the top of the support platform 2. The turntables 3 are symmetrically distributed on the upper surface of the fixed platform 1. The side walls of the turntable 3 are rotatably connected to the gears 4. The side walls of the gears 4 are fixedly connected to the worm gears 5. A plurality of motors 6 are fixedly connected to the top of the support platform 2. The output end of the motor 6 is fixedly connected to the worm 7, which is engaged with the worm gear 5. A slide groove 8 is provided inside the support platform 2, and a plurality of sliding columns 9 are provided inside the support platform 2. The sliding columns 9 are all slidably connected to the inside of the slide groove 8. The tops of the sliding columns 9 are fixedly connected to racks 10, which are engaged with the gear 4. One end of the sliding column 9 is fixedly connected to a connecting ring 11. The side walls of the fixed platform 1 are provided with sliding components, which are used to provide cable sliding.

[0024] Specifically, when the cable tension needs to be adjusted, the cable is first evenly wound around the surface of the roller. After starting the motor 6, the operation of the motor 6 will apply power to the worm 7, so that the worm 7 starts to rotate. During the rotation process, the worm 7 drives the worm wheel 5 to rotate through its meshing relationship with the worm wheel 5. The rotation of the worm wheel 5 further drives the gear 4 on its side wall to rotate. The gear 4 meshes with the rack 10 on the side wall of the turntable 3, so that the rack 10 slides horizontally inside the slide groove 8. The horizontal sliding of the rack 10 will cause the sliding column 9 at its bottom to move synchronously inside the slide groove 8. The displacement of the rack 10 will be achieved through the connection with the connecting ring 11 The synchronous movement of the connecting ring 11 will cause the roller inside it to move. By adjusting the relative positions of multiple connecting rings 11, the cable tension can be accurately changed, thereby keeping the cable within the optimal tension range. This adjustment method can effectively prevent potential damage or performance degradation caused by loose or over-tight cables. In addition, compared with electrical or hydraulic structures, the structure of this mechanical adjustment system is relatively simple and easy to operate and maintain. Electrical and hydraulic systems usually require complex control and maintenance, while this mechanical adjustment makes maintenance work more efficient and convenient, reducing the risk of system failure and maintenance costs.

[0025] Reference Figure 3 The sliding assembly includes a slide 12, which is arranged on the side wall of the fixed platform 1, and is rotatably connected to a closing cover 13 inside the fixed platform 1. The side wall of the fixed platform 1 is fixedly connected to a card column 14, and the side wall of the closing cover 13 is fixedly connected to a rotating plate 15. The side wall of the rotating plate 15 is rotatably connected to a turning handle 16, and the turning handle 16 is rotatably connected to a connecting shaft 17. The outer wall of the connecting shaft 17 is rotatably connected to a connecting frame 18, and a transverse groove 19 is provided inside the connecting frame 18. A slider 20 is provided inside the connecting frame 18, and a limit ring 21 is fixedly connected to the inside of the slider 20. The limit ring 21 is slidably connected to the inside of the transverse groove 19, and the upper and lower surfaces of the limit ring 21 are fixedly connected to the limit ring 21. The side wall of the slider 20 is fixedly connected to a connecting column 22, and a spring 23 is sleeved on the outer wall of the connecting column 22. One end of the connecting column 22 is fixedly connected to a buckle frame 24.

[0026] Specifically, an extra space is provided inside the fixed platform 1 to facilitate operation and component replacement during maintenance and overhaul of the equipment. This extra space is achieved by opening and closing the closing cover 13, which is controlled by the turning handle 16. When the turning handle 16 is operated, the turning handle 16 rotates on the side wall of the rotating plate 15 after being subjected to force and changes its own tilt angle. Through the connecting shaft 17, this rotational movement is transmitted to the connecting frame 18, causing it to rotate accordingly and adjust its tilt angle. The rotation of the connecting frame 18 further drives the buckle frame 24 to move, causing it to disengage from the engaging state with the card column 14, thereby opening the closing cover 13. When the closing cover 13 needs to be re-engaged, the operator turns the turning handle 1 6 is pulled back, which will cause the buckle frame 24 to be re-sheathed on the outer wall of the clamping column 14. At this time, the connecting frame 18 will move to the left. Since the buckle frame 24 limits its position, this movement will drive the slider 20 to slide inside the connecting frame 18. The sliding of the slider 20 is kept stable by the spring 23, and the setting of the limit ring 21 ensures that the sliding stroke of the slider 20 will not exceed the limit. The sufficient maintenance space ensures more efficient operation during maintenance and replacement of parts, which can significantly reduce the downtime of the equipment, thereby improving production efficiency. The extra space designed in this way not only improves the maintenance convenience of the equipment, but also reduces production delays caused by failures, ensuring that the equipment can remain in optimal operating condition.

[0027] Working principle: When the cable tension needs to be adjusted, the cable is first wound around the surface of the roller and then the motor 6 is started. The motor 6 outputs to the worm 7 to drive the worm 7 to rotate. During the rotation process, the worm 7 drives the worm wheel 5 to rotate through the meshing relationship with the worm wheel 5. When the worm wheel 5 rotates, it is connected with the gear 4 and drives the gear 4 on the side wall of the worm wheel 5 to rotate on the side wall of the turntable 3. The rotation process of the gear 4 is in meshing relationship with the rack 10, so that the rack 10 drives the sliding column 9 at its bottom to slide horizontally inside the slide groove 8. The displacement of the rack 10 will drive the connecting ring 11 on its side wall to displace synchronously. The displacement of the connecting ring 11 can drive the roller inside it to displace. The relative position change of multiple connecting rings 11 can realize the change of the cable tension, keep the cable in the optimal tension range, avoid damage or performance degradation due to looseness or overtightening, and is simpler and easier to maintain than the electrical structure or hydraulic structure. Extra space is provided inside the fixed table 1. The additional space makes it easy to operate and replace parts of the equipment during maintenance and overhaul. This space is opened and closed by rotating the cover 13. When operating the opening and closing of the cover 13, the handle 16 is toggled. After the handle 16 is subjected to force, it will rotate on the side wall of the rotating plate 15 and change its own tilt angle, and the connection through the connecting shaft 17 will drive the connecting frame 18 to rotate and change its tilt angle. After the connecting frame 18 rotates, it can drive the buckle frame 24 to move and disengage from the engagement state with the card column 14, and then open the cover 13. When re-engaging, the buckle frame 24 is sleeved on the outer wall of the card column 14 and the handle 16 is pulled back. At this time, the connecting frame 18 will move to the left. Due to the restricted position of the buckle frame 24, the slider 20 will slide inside the connecting frame 18 and be kept stable by the spring 23. The setting of the limit ring 21 ensures that the sliding stroke of the slider 20 is limited. The sufficient space makes the process of repairing and replacing parts more efficient, thereby reducing equipment downtime and improving production efficiency.
