Description

Technical Field

[0001] This utility model relates to the field of cable winding and unwinding technology, and in particular to a cable winding and unwinding device with automatically adjustable tension. Background Technology

[0002] With the development of modern industry, cables are being used more and more widely. From power transmission to data communication, various scenarios require different types of cables. In actual operation, the cable winding and unwinding process is very important, as it not only affects construction efficiency but also directly relates to the quality and service life of the cable.

[0003] Patent CN220811386U discloses a cable laying and rewinding device. This patent integrates components such as a movable frame, support plate, support block, motor, rotating roller, cable guide plate, movable notch, first screw, and pressure block to effectively support and fix the cable. Specifically, the rotating roller is rotatably connected to the support plate, the annular cable guide plate is fixedly connected to the rotating roller, and the first screw is rotatably connected to one of the cable guide plates and passes through the pressure block, allowing it to slide up and down along the movable notch. This achieves tight clamping and fixing of one end of the cable, preventing it from loosening and falling off. Furthermore, the support plate stably supports the rotating roller, and the support block is used to fix the motor, ensuring the overall stability of the device. Regarding the stability and reliability of the structure, this design solves the problem that existing equipment cannot easily tighten and fix cables, improves the efficiency of cable winding and unwinding, and helps prevent the cable from being too loose after winding and avoids tangling during winding and unwinding. However, in practical applications, although the above patent provides an effective cable fixing and initial tensioning solution, it still has some shortcomings. The patent can only manually adjust the distance between the adjusting guide wheel and the rotating wheel to adjust the tension of the cable winding. It lacks an effective dynamic tension adjustment mechanism, which means that it cannot automatically adjust to maintain the optimal tension level when facing complex terrain or long-distance laying, thus affecting the quality and efficiency of cable laying.

[0004] Therefore, there is an urgent need to provide a cable winding and unwinding device that can automatically adjust the tension. Utility Model Content

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0024] Example 1: Please refer to Figures 1-3 A cable reeling and unloading device with automatically adjustable tension includes a fixed frame 1. Four symmetrically arranged casters 2 are mounted on the bottom of the fixed frame 1 for easy movement. Symmetrically arranged pull rods 3 are fixed to the top of the fixed frame 1 for easy pushing or pulling by the operator. The upper ends of the pull rods 3 are covered with sponge sleeves 20 to improve grip comfort and reduce hand fatigue from prolonged use. Symmetrically arranged guide plates 4 are fixed to the top of the fixed frame 1, and these guide plates 4 collectively support a feeding rod 5. The feeding rod 5 can move up and down along the guide plates 4 to adjust its height. Adjustments are made to the following: Handles 501 are fixed to both ends of the feeding rod 5 for easy operation of pulling out or inserting the feeding rod 5 into the cable reel. A symmetrically distributed lead screw 6 is rotatably mounted on the top of the fixing frame 1. The lead screw 6 is located behind the guide plate 4. Each lead screw 6 has a handwheel 7 at its lower end. Rotating the handwheel 7 drives the lead screw 6 to rotate in either the forward or reverse direction. An anti-slip sleeve 17 is fitted over the handwheel 7 to increase friction and facilitate easier rotation by the operator. A symmetrically distributed guide rod 8 is fixed to the top of the fixing frame 1. The guide rod 8 is located on the front side of the guide plate 4. Each guide rod 8... A placement frame 9 is slidably mounted on the guide rod 8. The placement frame 9 supports the left and right ends of the feeding rod 5, ensuring the stability of the feeding rod 5, and is threadedly connected to the lead screw 6. When the lead screw 6 rotates, the placement frame 9 can move up and down along the guide rod 8, thereby realizing the height adjustment of the feeding rod 5. A protective pad 901 is provided on the inner surface of each placement frame 9 to reduce friction and wear between the feeding rod 5 and the placement frame 9. A connecting frame 902 is fixedly connected to the front side of each placement frame 9, and an electric slide rail 903 is installed on each connecting frame 902. The electric slide rail 903 on the left side is equipped with... A tension sensor 904 is provided, with its detection end connected to one end of a fixed shaft 905. A tension wheel 906 is rotatably mounted on the fixed shaft 905. A fixing block 907 is mounted on the electric slide rail 903 on the right side to support the other end of the fixed shaft 905. A fully automatic tension control box 908 is provided on the left side of the fixing frame 1. The fully automatic tension control box 908 is connected to the tension sensor 904 via a signal connection. By receiving signals from the tension sensor 904, it analyzes and sends commands to the electric slide rail 903 to control the position of the tension wheel 906, thereby adjusting the cable tension.

[0025] When using this device, first, hold handle 501 and pull out the feed rod 5. Then, place the cable reel between the two guide plates 4. Next, pass the feed rod 5 through the center of the cable reel, ensuring that both ends of the feed rod 5 are correctly placed on the placement frame 9 for stability. Then, turn the handwheel 7 to rotate the lead screw 6, causing the placement frame 9 to move up and down along the guide rod 8, adjusting the height of the feed rod 5 and the cable reel on it to prevent the cable from falling and causing damage during feed and take-up. Then, pull out one end of the cable and pass it around the bottom of the tension wheel 906, using the tension wheel 906 to hold the cable in place. Then, hold handle 501 and rotate the feed rod 5 in the forward or reverse direction to feed or take up the cable as needed. During the feed or take-up process, the cable will exert a certain tension on the tension wheel 906. This tension will be transmitted to the tension sensor 904, which will monitor the cable tension in real time and convert the monitored data into electrical signals, which will be sent to the fully automatic tension control box 908. The fully automatic tension control box 908 receives these signals. The system analyzes the signal according to preset parameters. Based on the analysis results, if the fully automatic tension control box 908 detects that the cable tension exceeds the set safety range, it will issue a command to the corresponding electric slide rail 903. When the cable tension is too high, the fully automatic tension control box 908 will control the electric slide rail 903 to drive the entire fixed shaft 905 and tension wheel 906 to rise, thereby reducing the pressure on the cable and lowering the tension. Conversely, if the cable tension is too low, the fully automatic tension control box 908 will control the electric slide rail 903 to drive the fixed shaft 905 to move downward, causing the tension wheel 906 to drop, increasing the pressure on the cable and raising the tension to a suitable level. As the electric slide rail 903 moves, the change in tension will be captured again by the tension sensor 904 and will continue to be fed back to the fully automatic tension control box 908, forming a closed-loop control system. In this way, the cable tension can be continuously monitored and adjusted to ensure that a constant and safe tension value is maintained throughout the entire cable laying or winding process.

[0026] Example 2: Based on Example 1, please refer to... Figure 4 The placement rack 9 is fitted with a limiting cover 10. The limiting cover 10 has a circular hole at its center, designed to allow the handle 501 of the feeding rod 5 to pass through. The limiting cover 10 has locking rods 11 on both the front and back sides, and the placement rack 9 has corresponding locking holes on the front and back sides. The limiting cover 10 is securely installed by locking the locking rods 11 into the locking holes. A connecting rod 12 is fixed to the locking rod 11, and one end of an anti-loss rope 18 is fixed to the connecting rod 12. The other end of the anti-loss rope 18 is fixed to the limiting cover 10 to prevent the locking rods 11 from being lost accidentally.

[0027] Before removing the feeding rod 5, the locking rod 11 must first be pulled out from the locking hole on the placement frame 9 to remove the limiting cover 10. Then, the feeding rod 5 can be easily pulled out. After the cable reel is installed, when reinstalling the feeding rod 5, first attach the limiting cover 10 to the placement frame 9 and make the handles 501 at both ends of the feeding rod 5 pass through the round holes of the limiting cover 10. Finally, insert the locking rod 11 into the locking holes on both sides of the placement frame 9 to fix the limiting cover 10. In this way, the limiting cover 10 can effectively limit the left and right movement of the feeding rod 5 during rotation, prevent it from deviating from the predetermined path, and ensure the stability and accuracy of the feeding operation.

[0028] Please see Figure 5 The connecting frame 902 on the left side has a rotating plate 14 rotatably mounted on its lower part via a rotating shaft 13. A damping ring 19 is fitted around the rotating shaft 13 to provide appropriate resistance and prevent the rotating plate 14 from moving or flipping due to external forces. The rotating plate 14 has a sliding groove, and a guide sleeve 15 is slidably installed on the sliding groove to guide the cable winding and unwinding direction and reduce the swaying of the cable during winding and unwinding. One end of the rotating plate 14 is threaded with a fixing bolt 16, and the connecting frame 902 on the right side has a threaded hole that matches the fixing bolt.

[0029] Before inserting the cable reel, first rotate the fixing bolt 16 in the reverse direction to move it upward and disengage it from the threaded hole on the connecting bracket 902, and release the rotating plate 14. Then, rotate the rotating plate 14 upward around the rotating shaft 13 to make enough space to place the cable reel. After the cable reel is installed, pull the rotating plate 14 downward to reset it, and rotate the fixing bolt 16 in the forward direction to screw it into the threaded hole on the connecting bracket 902, thus completing the fixing of the rotating plate 14. Before the cable reel starts to unload, pull the end of the cable around the tensioning wheel 906 and let it pass through the guide sleeve 15. By adjusting the position of the guide sleeve 15 in the groove, the cable can be effectively limited to avoid unnecessary shaking or deviation of the cable when it is unloaded, ensuring the stability and smoothness of the unloading process.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
