Description

Technical Field

[0001] This invention relates to the field of cable winding and unwinding technology, and in particular to an adjustable winding and unwinding device for power transmission cables and its usage method. Background Technology

[0002] With the rapid development of power transmission line projects, electricity is being delivered to more distant places by erecting transmission lines between cities, thereby improving the local power supply situation. In power transmission line projects, cable retractors are often used to retract and deploy cables. Currently, cable retractors are professional equipment mainly used for the installation, laying and recycling of cables. They can use mechanical devices to replace manual labor for the laying and winding of power conductors.

[0003] For example, CN108394765A discloses a cable winding and unwinding device and a power emergency repair equipment, including a bracket, a first drive mechanism, two wheel plates, a main shaft, multiple adjusting rods, and an axial adjustment mechanism; the two wheel plates are arranged opposite each other, and the main shaft passes through the center of the two wheel plates; multiple adjusting rods are evenly distributed in a circle between the two wheel plates to form a winding shaft, and multiple sliding grooves are provided on the two wheel plates, the number of sliding grooves being the same as the number of adjusting rods, the sliding grooves being evenly distributed on the wheel plates and arranged along the axial direction of the wheel plates, allowing the adjusting rods to slide within the sliding grooves; the axial adjustment mechanism is located between the main shaft and the multiple adjusting rods, and is used to adjust the cross-sectional diameter of the winding shaft formed by the multiple adjusting rods. Small; the first drive mechanism is located on the bracket and is connected to the main shaft, used to control the rotation of the main shaft to wind the cable onto the winding shaft formed by multiple adjusting rods; the cable winding and power repair equipment solves the problems of manual winding, which results in inconsistent winding sizes, easy scattering, and inconvenient recycling and transportation. However, although the existing winding and winding devices use mechanical winding, they have low automation and lack precise automatic tension control functions. They cannot adjust the winding and winding force in real time according to factors such as cable material, temperature, and load changes, resulting in uneven cable stress or excessive wear. They cannot achieve proactive prevention and intelligent early warning, and the adjustable structure is simple.

[0004] For example, CN117185033A discloses a cable winding and unwinding tension adjustment device, including a mounting plate. A winding and unwinding mechanism is fixedly connected to the top of the mounting plate, and a tension adjustment auxiliary mechanism is also fixedly connected to the top of the mounting plate. This cable winding and unwinding tension adjustment device uses a first transmission mechanism to drive a first transmission shaft to rotate, which in turn drives a winding and unwinding tube to rotate. The winding and unwinding tube winds and unwinds the cable, while the tension adjustment auxiliary mechanism assists in this process. The device enables the winding and unwinding tube to maintain adaptive adjustment of the cable tension throughout the winding and unwinding process, improving the stability of tension adjustment. This effectively avoids situations where poor tension stability during cable winding and unwinding leads to loose cable winding or unstable tension during unwinding, resulting in a loose cable. However, this device can only adjust the cable winding and unwinding based on tension alone, and cannot adjust the winding and unwinding force in real time according to other factors such as cable material and temperature. This can lead to excessive wear and damage to the cable. The adjustable structure is limited, and improvements are needed in terms of intelligence and preventative features.

[0005] Therefore, it is necessary to provide an adjustable winding and unwinding device for power transmission cables and a method for using it to solve the problems mentioned in the background art. Summary of the Invention

[0017] A method for using an adjustable winding and unwinding device for power transmission cables, comprising the following steps: (The method utilizes any one of the aforementioned adjustable winding and unwinding devices for power transmission cables.)

[0018] Step 1: Equipment installation. Place the vehicle frame in the desired location and ensure it is stable. Ensure the power cable is in a suitable position for winding and unwinding. Install the winding and unwinding mechanism to the installation position on the vehicle frame and fix it with positioning bolts. Install the wire roller on the vehicle frame and ensure it can rotate freely. Install the wire feed adjustment module on the vehicle frame and ensure its position is in front of the wire roller. The power cable passes through the wire feed adjustment module and moves horizontally along the vehicle frame to guide the power cable to be wound sequentially on the winding and unwinding mechanism during winding operations.

[0019] Step 2: Start the device, power it on, and test it to ensure all components are in normal working order. Then, depending on the type of power cable and the working environment, adjust the horizontal displacement of the cable feeding adjustment module to allow the power cable to be smoothly wound onto the take-up and unwinding mechanism. The hoist motor drives the gear transmission system to control the rotation of the main shaft, thereby winding or unwinding the power cable. The conductor roller guides the sequential winding of the power cable. In the cable feeding adjustment module, the connecting plate frame is driven by a screw to move. The electric adjustment rod is equipped with a conductor sleeve and a conductor wheel. The position of the conductor wheel is adjusted by the electric adjustment rod and the conductor sleeve to ensure smooth transmission of the power cable.

[0020] Step 3: Monitoring and Adjusting the Operating Status. During operation, the device continuously monitors the status and working environment of the power transmission cable. Based on the environmental analysis module, it acquires and analyzes environmental characteristic data of the power transmission cable's winding and unwinding process, inputting this data into the regression prediction model. A high-definition scanning camera installed inside the conductor sleeve scans and identifies the surface of the power transmission cable, capturing high-resolution images of its surface features, which are then input into the regression prediction model. Based on preset pressure values ​​or control signals, when tension is excessive, the pneumatic stop and compensation device is adjusted, driving the compensation motor through gear meshing to drive the coupling transmission, achieving stop and precise control of the winding and unwinding mechanism. Tensile stress is monitored using the inner shaft and outer tube in the main shaft, along with several internal springs and resistance strain gauges evenly distributed on the inner shaft. Pulse signals are released through the absolute encoder module, outputting the number of winding turns, continuously monitoring the operating status of the power transmission cable, and promptly detecting and handling any abnormalities.

[0021] Step 4: End the operation. After the wire is retracted or released, stop the operation of the retracting and releasing mechanism through the control system interface. At the same time, disconnect the power supply or other power sources and wait for the power cable to completely stop moving. Check the status of the device and the power cable to ensure that the equipment is not damaged and perform necessary maintenance in a timely manner.

[0022] The present invention provides an adjustable winding and unwinding device for power transmission cables and a method for using the same, which has the following beneficial effects:

[0023] 1. The device of this invention uses mechanical devices to replace manual labor in the laying and winding of power conductors, which greatly improves the degree of automation and reduces labor costs and labor intensity;

The device of the present invention has a precise automatic tension control function, which can adjust the winding and unwinding force in real time according to factors such as cable material, temperature, and load changes, so that the cable is subjected to uniform force, reducing excessive wear and thus extending the service life of the cable.

[0025] 3. The device of the present invention is equipped with an environmental analysis module, which is used to acquire and analyze the environmental characteristics data of the operation of power transmission cables and input the data into the regression prediction model. This enables the device to proactively prevent and intelligently warn of potential problems, thereby improving the reliability and safety of the equipment.

[0026] 4. The wire feeding adjustment module of the device of the present invention adopts a structure such as a connecting plate frame, an electric adjustment rod, and a wire wheel, which can be horizontally displaced as needed, so that the power transmission cable is sequentially wound on the take-up and unwinding mechanism, thereby improving the flexibility and applicability of the device.

[0027] 5. The device of the present invention uses multiple high-definition scanning cameras to scan and identify power transmission cables, and combines the image processing module to extract surface features, which can promptly detect problems such as scratches, cracks, and damage to the cables, thereby improving the maintenance efficiency of the equipment and the safety of the cables.

[0060] In a preferred embodiment, the main shaft 5 includes an inner shaft 51, on which an outer tube 52 is fitted. Several sets of inner springs 53 are symmetrically arranged between the inner shaft 51 and the outer tube 52. Several resistance strain gauges 54 are also evenly distributed on the inner shaft 51. One end of each inner spring 53 is in contact with a resistance strain gauge 54. The control system is equipped with a tensile stress monitoring module, which is connected to both the inner springs 53 and the resistance strain gauges 54. This configuration enables the main shaft 5 to maintain strength and stability while timely monitoring and adjusting the tensile stress of the cable, ensuring that the cable operates under appropriate tension, thus improving the stability and reliability of the system.

[0061] In a preferred embodiment, the pneumatic brake stop and refill device 4 includes a coupling 41, which is laterally rotatably mounted on one side of the take-up and release mechanism 3. One end of the outer tube 52 of the main shaft 5 on the take-up and release mechanism 3 is rotatably mounted inside the coupling 41 via a bearing. A pneumatic cavity 48 is provided inside the coupling 41, and a piston rod 42 is slidably mounted inside the pneumatic cavity 48. A fastening spring 49 is mounted on the piston rod 42 inside the pneumatic cavity 48. A pneumatic pipe 43 is also mounted on the coupling 41 and is connected to the pneumatic cavity 48. A refill motor 44 is mounted on one side of the take-up and release mechanism 3. The refill motor 44 is driven by gear meshing with the coupling 41 and is connected to the control system. The above configuration makes the entire device structure more compact, realizes flexible control of the piston rod 42, and the gear transmission between the refill motor 44 and the coupling 41 makes the refill process more stable and controllable.

[0062] In a preferred embodiment, a stop ring 47 is also installed on the piston rod 42 near the end of the outer tube 52 of the main shaft 5. The stop ring 47 is fitted onto the reduction shaft 45. A stop shaft 46 is installed on the inner shaft 51 inside the outer tube 52. The end face of the stop shaft 46 is provided with a circular tooth groove. The reduction shaft 45 is provided with a tooth surface structure that matches it. A pressure spring is installed between the reduction shaft 45 and the stop ring 47. The above configuration can effectively limit the movement range of the piston rod 42, realize precise control of the position of the piston rod 42, and ensure the accuracy and reliability of the stop and recovery actions.

[0063] In a preferred embodiment, the control system is further equipped with an absolute encoder module, which releases pulse signals based on the number of rotations of the take-up and release mechanism 3 and outputs a winding count characteristic. This configuration enables the control system to accurately determine the current state of the take-up and release mechanism 3, and to adjust the operating parameters by acquiring the position information of the take-up and release mechanism in real time, thereby achieving precise control of the entire system.

[0064] In the preferred embodiment, the control system is equipped with an environmental analysis module to acquire and analyze the environmental characteristics data of the power transmission cable operation and winding, and input the acquired environmental characteristics data into the regression prediction model to provide a reference for the winding and winding operation characteristics of the winding and winding mechanism 3. The pneumatic stop and compensation device 4 controls the winding and winding mechanism 3 to wind and wind according to the preset pressure value or control signal. The above settings, by acquiring and analyzing the characteristic data of the power transmission cable operation and winding environment, enable the system to make corresponding adjustments in advance, and at the same time help the system to detect potential problems or abnormalities in a timely manner to cope with environmental changes.

[0065] In summary, the present invention provides an adjustable winding and unwinding device for power transmission cables and its usage method. In this invention, the winding and unwinding mechanism 3 employs advanced intelligent control technology. By constructing a regression prediction model, which deeply integrates the physical characteristics of the power transmission cable itself and external environmental factors (such as temperature, humidity, wind speed, and sunlight), it achieves real-time, accurate prediction and adaptive adjustment of key parameters such as tension and speed during the cable winding process, thereby greatly reducing the risk of cable breakage due to improper winding operations. Furthermore, the present invention is equipped with a pneumatic stop and compensation device 4. This device can quickly drive the pneumatic control piston rod 42 when the cable tension exceeds the safety threshold, causing the deceleration shaft 45 to engage with the resistance shaft. The tight engagement of the 46 mechanism forces the take-up and retraction mechanism 3 to stop promptly, preventing cable damage due to excessive stretching. Simultaneously, the return motor 44 precisely controls the cable's return release after stopping, ensuring the cable tension smoothly returns to a safe range, effectively improving the cable's protective performance during take-up and retraction. Through these technological innovations, this invention successfully achieves highly intelligent and safe control over the entire process of power transmission cable take-up and retraction, greatly improving work efficiency, reducing unnecessary losses, and strongly guaranteeing the safety and stability of power transmission. This invention is ingeniously designed, simple in structure, scientifically sound, green, low-carbon, and environmentally friendly, with strong practical application value, good economic and social benefits, and can be widely applied in actual production.
