[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 – Figure 4 As shown, this embodiment provides a cable traction device, including a housing 1 with an opening on one side. A traction motor 11 is installed at the opening, and a traction wheel 12 is installed on the traction motor 11. A pressure wheel 13 is provided below the traction wheel 12. A cable storage module 2 is provided on the side of the housing 1 away from the opening. A tensioning wheel 3 is provided between the cable storage module 2 and the traction wheel 12. A tension detection module 4 is provided between the tensioning wheel 3 and the traction wheel 12. The tensioning wheel 3 is installed on the housing 1 through a sliding adjustment mechanism 5.

[0033] By installing a tension detection module 4 between the tensioning wheel 3 and the traction wheel 12, the tension of the cable during traction can be monitored in real time. The tensioning wheel 3 is mounted on the housing 1 via a sliding adjustment mechanism 5. When the tension detection module 4 detects a change in cable tension, the sliding adjustment mechanism 5 adjusts the position of the tensioning wheel 3 accordingly, thereby achieving dynamic adjustment of the cable tension. This configuration ensures that the cable maintains appropriate tension during traction, preventing damage due to excessive tension or slackness and poor traction caused by insufficient tension. This effectively improves the quality and efficiency of cable traction and ensures the stability and reliability of the traction process.

[0034] The sliding adjustment mechanism 5 includes a support frame 51, the tensioning wheel 3 is mounted on the support frame 51, and a pushing module including a sliding shell 52 is provided below the support frame 51. A pushing part for pushing the support frame 51 is installed in the sliding shell 52.

[0035] The sliding adjustment mechanism 5 includes a support frame 51 and a push module. The tension wheel 3 is mounted on the support frame 51. The sliding housing 52 and the push part in the push module provide stable support and push for the support frame 51. The push part can precisely control the sliding direction and distance of the support frame 51, thereby achieving precise adjustment of the position of the tension wheel 3. This structural design makes the sliding adjustment mechanism 5 compact, easy to adjust, and stable in operation. It can quickly and accurately adjust the position of the tension wheel 3 based on the feedback information from the tension detection module 4, improving the device's response speed and accuracy to cable tension adjustment, and ensuring that the cable is always in the optimal traction tension state.

[0036] The pushing part includes a first drive motor 53, and a threaded sleeve 54 is installed at the output end of the drive motor 53. A screw is engaged in the threaded sleeve 54, and one end of the screw extending out of the threaded sleeve 54 is fixedly installed on the support frame 51.

[0037] The system employs a combination of a first drive motor 53, a threaded sleeve 54, and a screw. The first drive motor 53 serves as the power source, and the threaded sleeve 54, installed at its output end, meshes with the screw. When the motor rotates, the threaded sleeve 54 rotates, causing the screw to move axially, thereby pushing the support frame 51 to slide. The threaded drive offers advantages such as high transmission accuracy, smooth transmission, and good self-locking performance, enabling precise control of the movement distance of the support frame 51 and making the position adjustment of the tensioning wheel 3 more accurate and stable. This pusher structure is simple and reliable, easy to manufacture and maintain, and provides stable tension adjustment power for the cable traction device, ensuring long-term stable operation of the device.

[0038] Example 2

[0039] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the pushing part includes a second drive motor 56, a worm gear 57, a worm 58, and a helical rack 59;

[0040] The worm gear 57 and the worm 58 are meshed together, and one end of the worm 58 is connected to the output end of the second drive motor 56;

[0041] A helical rack 59 is slidably mounted on the sliding shell 52 on the side of the worm gear 57, and one end of the helical rack 59 is fixedly mounted on the support frame 51.

[0042] The system employs a combination structure of a second drive motor 56, a worm gear 57, a worm 58, and a helical rack 59. The worm gear 57 meshes with the worm 58, one end of which is connected to the second drive motor 56. The helical rack 59 is slidably mounted on the sliding housing 52 on the side of the worm gear 57, meshing with it, and one end is fixed to the support frame 51. The worm gear 57 and worm 58 transmission has advantages such as a large transmission ratio, compact structure, smooth operation, low noise, and good self-locking performance. It can convert the rotational motion of the motor into the linear motion of the helical rack 59, thereby driving the support frame 51 to move. This structure can provide a large driving force, making it suitable for scenarios requiring a large tension adjustment range, while ensuring the smoothness and accuracy of the adjustment process, thus improving the applicability and reliability of the device.

[0043] Example 3

[0044] Based on Embodiment 1 or Embodiment 2, the tension detection module 4 in this embodiment includes a guide groove 41 formed on the side wall of the housing 1, a support seat 42 slidably disposed in the guide groove 41, and a guide wheel 43 disposed on the support seat 42;

[0045] A spring 44 is provided at one end of the support base 42. One end of the spring 44 is connected to the support base 42, and the other end is installed on the side wall of the housing 1.

[0046] The support base 42 is provided with a detection part 45 for detecting the position of the guide wheel 43 on its side.

[0047] When the cable tension changes, the guide wheel 43 experiences a change in cable pressure, causing the support seat 42 to slide within the guide groove 41. The elastic force of the spring 44 ensures that the guide wheel 43 remains in contact with the cable and reflects changes in tension. The detection unit 45 can obtain real-time information about the cable tension by detecting changes in the position of the support seat 42 or the guide wheel 43. This tension detection module 4 has a simple structure and low cost, and can sensitively detect minute changes in cable tension, providing accurate feedback signals to the sliding adjustment mechanism 5 and ensuring the timeliness and effectiveness of tension adjustment.

[0048] Specifically, the detection unit 45 is a distance measurement sensor. Distance detection can be achieved using components such as Hall effect sensors or laser rangefinders. The distance measurement sensor can accurately measure the positional changes of the support base 42 or guide wheel 43 within the guide groove 41, thereby obtaining the magnitude of the cable tension force in real time and accurately. The distance measurement sensor has advantages such as high measurement accuracy, fast response speed, and strong anti-interference capability, providing reliable data support for tension force detection. This allows the sliding adjustment mechanism 5 to adjust according to the precise tension force signal, further improving the control accuracy of the cable traction device on the tension force and ensuring the stability and consistency of the cable tension force during traction.

[0049] Example 4

[0050] The difference between this embodiment and embodiment three is that the detection unit 45 in this embodiment includes a detection platform arranged along the sliding direction of the support base 42, and a limit switch is provided at each end of the detection platform.

[0051] When the support base 42 slides to the extreme positions at both ends of the detection table, the limit switch is triggered, thereby determining whether the cable tension exceeds the preset safety range. This detection unit 45 has a simple structure and low cost, and can effectively monitor the extreme state of cable tension. When the tension is too high or too low, it promptly issues a signal to remind the control system to adjust or stop operation, avoiding cable damage or device malfunction due to abnormal tension, thus improving the safety and reliability of the cable traction device.

[0052] Preferably, at least three limit switches are evenly arranged on the detection platform along the sliding direction of the support base 42. The presence of at least three limit switches, or even more (e.g., 5-9), allows for segmented detection of cable tension. Triggering the limit switches at different positions indicates that the cable tension falls within different ranges, enabling the control system to adopt different adjustment strategies based on the specific tension conditions, achieving more precise tension control. This arrangement increases the flexibility and adaptability of the detection, meeting the precise control requirements of cable tension under different operating conditions, and further improving the performance and applicability of the device.

[0053] The clamping roller 13 is mounted to the housing 1 via the lifting module 6. The lifting module 6 allows for easy adjustment of the height of the clamping roller 13, thereby changing the distance and clamping force between the clamping roller 13 and the traction roller 12. This configuration allows the device to adapt to cables of different diameters and specifications. By adjusting the position of the clamping roller 13, it ensures that the cable is reliably clamped during traction, preventing slippage and improving the versatility and applicability of the device, meeting the needs of various cable traction operations. Specifically, the structure of the lifting module 6 can be either a pre-installed lifting motor or a configuration similar to the sliding adjustment mechanism 5.

[0054] Preferably, a pressure sensor is provided between the traction motor 11 and the housing 1;

[0055] And / or, a pressure sensor is provided between the lifting module 6 and the housing 1.

[0056] The pressure sensor can monitor in real time the pressure exerted on the traction motor 11 during traction and the pressure changes of the lifting module 6 when adjusting the clamping roller 13. Through the feedback signal from the pressure sensor, the control system can understand the working load of the device in real time and take timely protective measures when abnormal pressure occurs, such as adjusting the traction speed and clamping force, to avoid damage to the device or cable traction accidents due to overload. This setup improves the intelligence level and safety performance of the device, ensuring the safe and stable operation of cable traction.

[0057] Before the cable pulling operation begins, the height of the clamping wheel 13 is adjusted using the lifting module 6 according to the cable's diameter and specifications. This ensures that the distance between the clamping wheel 13 and the traction wheel 12 matches the cable size, guaranteeing that the cable can be reliably clamped. The cable is then passed through the traction wheel 12, passes sequentially around the guide wheel 43 and the tensioning wheel 3, and is fed into the cable storage module 2, completing the cable installation.

[0058] The traction motor 11 is started, and the traction wheel 12 begins to rotate, driving the cable to move through friction and pulling it to the target position. During the traction process, the tension detection module 4 monitors the cable tension in real time. Once a change in tension is detected, the sliding adjustment mechanism 5 immediately responds and adjusts the position of the tension wheel 3 to achieve dynamic adjustment of the tension. At the same time, the pressure sensor monitors the pressure changes of the traction motor 11 and the lifting module 6 in real time, providing the control system with information on the device's workload. If the pressure is abnormal, protective measures are taken in a timely manner to ensure the safe and stable operation of the traction operation.
