Description

Technical Field

[0001] This invention belongs to the field of cable winding and unwinding control technology, and specifically relates to a cable adjustment device. Background Technology

[0002] In ionizing radiation environments, strong radiation is extremely harmful to the human body, and stable automated equipment can replace repetitive human tasks. However, taking a strong gamma field as an example, gamma particles damage the insulating gate oxide layer, causing threshold drift in the MOS structure. Abnormal conduction can lead to short circuits and system failure. Most high-precision automated devices, such as tension sensors, photoelectric encoders, and force sensors, are difficult to use for extended periods in such environments.

[0003] Most existing mobile robots and other mobile devices are wired and equipped with cable reels and other cable take-up and take-up devices, which are often equipped with the aforementioned automated devices to complete the take-up and take-up of cables in order to meet the movement needs of robots. However, cable reels in radiation environments are mostly open-loop controlled, and the length of repeated take-up often cannot be kept consistent. Therefore, the key is to improve the mechanical structure and enhance the stability of repeated take-up of cable reels without adding electronic components. Summary of the Invention

[0004] To address the issues of errors in multiple cable reel windings under strong radiation fields, and the risk of personnel exposure due to the poor radiation resistance of most electronic components requiring manual adjustments, this invention aims to provide a purely mechanical cable adjustment device. This device improves the accuracy of multiple cable reel windings, enabling stable operation over extended periods under strong radiation fields. On one hand, it improves winding stability at low cost, enhancing the reliability of equipment in the nuclear field. On the other hand, it reduces or eliminates the need for personnel to enter radiation environments, fundamentally ensuring personal safety.

[0005] To achieve the above objectives, the present invention provides a cable adjustment device that works in conjunction with a motor-controlled cable storage reel in a radioactive environment. This device is used to adjust the winding and unwinding of cables within the reel. It includes a fixing device and a spring device mounted on a fixed base. The cable is released through the fixing device, and the spring device is used to adjust the winding and unwinding state of the cable.

[0006] Furthermore, the fixing device is a cylindrical structure with its tail end connected to the spring device. The cable passes through the inside of the fixing device to achieve the winding and unwinding operation, and the fixing device can fix the cable.

[0007] Furthermore, the fixing device is equipped with several rubber strips inside to increase the friction with the cable, thereby fixing the cable.

[0008] Furthermore, an adjusting screw is provided at the top of the fixing device. By rotating the adjusting screw, the rubber strip is squeezed, thereby increasing the friction between the rubber strip and the cable.

[0009] Furthermore, the spring device includes a spring and a spring retainer; one end of the spring is connected to the fixing device, and the other end is connected to the spring retainer, which is mounted on the fixing base; both the spring and the spring retainer are hollow structures, and the cable passes through the middle.

[0010] Furthermore, the spring can be replaced.

[0011] Furthermore, the fixing base is used to fix the entire device and the outer protection, reducing the amount of dust in the radioactive environment falling into the fixing device and the spring device.

[0012] The beneficial effects of this invention are as follows: This invention can effectively adjust the tension of the cable in a radiation environment. When the cable reel is too tight, the tension spring and the motor can counteract the excessive cable winding, thereby keeping the cable at an appropriate tension and avoiding inconsistent cable lengths after multiple windings.

[0014] In the diagram: 1-fixed device, 2-spring device, 3-fixed base, 4-adjusting screw. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] This invention provides a cable adjustment device (see...) Figure 1 This device, in conjunction with a motor-controlled cable storage reel in a radioactive environment, is used for adjusting the cable reel's winding and unwinding. It includes a fixing device 1 and a spring device 2 mounted on a fixed base 3. The cable is released through the fixing device 1, and the spring device 2 is used to adjust the cable's winding and unwinding state.

[0017] The fixing device 1 is a cylindrical structure with its tail end connected to the spring device 2. The cable passes through the inside of the fixing device 1 to realize the winding and unwinding operation. The fixing device 1 can fix the cable.

[0018] The fixing device 1 has several rubber strips inside, which are used to increase the friction with the cable, thereby fixing the cable.

[0019] An adjusting screw head 4 is provided at the top of the fixing device 1. By rotating the adjusting screw head 4, the rubber strip is squeezed, thereby increasing the friction between the rubber strip and the cable.

[0020] The spring device 2 includes a spring and a spring retainer; one end of the spring is connected to the fixing device 1 and the other end is connected to the spring retainer, which is mounted on the fixed base 3; both the spring and the spring retainer are hollow structures, and the cable passes through the middle.

[0021] The spring can be replaced.

[0022] The fixed base 3 is used to fix the entire device and the outer protection, reduce the amount of dust falling into the fixed device 1 and the spring device 2 in the radioactive environment, and facilitate cleaning.

[0023] In practical use, if the take-up and untake-up lengths are consistent during repeated cable winding operations, the cable adjustment device provided by this invention will not be triggered. When the cable reel takes up more cable, the spring is stretched. After the cable reel stops working, the spring's retraction pulls out a portion of the cable, returning the cable reel to its initial state. Therefore, personnel do not need to enter the radiation environment; the cable state can be effectively adjusted by the spring's tension after taking up more cable.

[0024] This cable adjustment device can select one of the technical solutions for cable fixing and adjustment according to the cable tension and cable diameter conditions of the application scenario, so as to meet the needs of on-site operation.

[0025] The device described in this invention is not limited to the embodiments described in the specific implementation. Other implementation methods derived by those skilled in the art based on the technical solution of this invention also fall within the scope of technical innovation of this invention.
