Description

Technical Field

[0001] This utility model relates to the field of tension-driven power line construction technology, and in particular to a segmented magnetic levitation anchor rope control system for power line construction. Background Technology

[0002] In tension-driven power line construction, pulley blocks and anchor ropes are core components responsible for supporting and securing the conductors, ensuring the safety and efficiency of the construction. However, existing pulley block and anchor rope systems suffer from several problems, including complex structures, severe wear, and a lack of real-time monitoring of anchor rope tension and position. These issues make it difficult for existing systems to meet the demands of modern power line construction for high efficiency, safety, and intelligence. Furthermore, existing equipment is costly to operate, inefficient, and unable to adapt to complex environments. In addition, traditional equipment often relies on external power supplies or fuel-powered generators, limiting its adaptability in field environments and increasing construction costs. With the development of new energy technologies, existing equipment urgently needs to be upgraded to adapt to the use of clean energy sources such as solar energy.

[0003] Magnetic levitation technology is a non-contact support technology that uses electromagnetic force to overcome gravity and achieve stable levitation of objects. In recent years, magnetic levitation technology has been widely used in many industrial fields. Its advantages in non-contact support, dynamic control and high energy efficiency make it an ideal solution to overcome the limitations of traditional mechanical systems. For example, the horizontal magnetic levitation conveyor belt technology proposed by Chinese utility model patent CN208802579U uses a segmented electromagnet array to achieve non-contact transportation of objects through a magnetic levitation conveyor belt system. By adjusting the levitation gap with electromagnetic force, it can stably transport items, verifying the feasibility of magnetic levitation technology in multi-degree-of-freedom environments. The literature (Stability Analysis of a Novel Side-mounted Magnetic Levitation System. Micromotors, 2025, 53 (01): 1-9+18) proves through simulation and experiment that the system can maintain stable levitation when subjected to vertical disturbance force and has strong displacement tracking ability. The article also explores the control strategy of the system in depth, especially the application of the PID control system, and verifies its stability and dynamic performance in actual operation.

[0004] Therefore, introducing magnetic levitation technology into overhead power line construction is clearly feasible. First, the non-contact support of magnetic levitation can significantly reduce the mechanical friction between the anchor rope and the pulley, reducing wear by more than 90%. Second, the independent control characteristics of the segmented electromagnet array can meet the dynamic adjustment requirements of the anchor rope in a multi-degree-of-freedom space. Finally, existing solar panel and battery technologies (such as the high cycle life of lithium iron phosphate batteries) can provide reliable outdoor power supply for the magnetic levitation system. These technological advantages make the magnetic levitation system a promising application in overhead power line construction. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-5As shown, a segmented magnetic levitation anchor rope control system for overhead power line construction includes a support frame 3, which is a hollow pentagonal frame. A fixing ring 1 is fixedly connected to the top of the support frame 3. A solar panel 2 is installed on the side of the support frame 3. A self-locking slide rail 4 is installed on the support frame 3, and a base 6 is movably connected to the self-locking slide rail 4. A magnetic levitation device 5 is fixedly connected to the top of the base 6. An anchor rope 8 is suspended inside the magnetic levitation device 5. A battery 10 is also installed inside the support frame 3. A data acquisition and monitoring device and a control device are installed inside the magnetic levitation device 5. In this embodiment, the control device includes a microcontroller, a signal amplifier, and a data transmission module. The microcontroller can be an ARM Cortex-M4 series for controlling the magnetic levitation device 5. In this embodiment, as shown... Figure 1 As shown, the support frame 3 is a pentagonal hollow frame structure. A self-locking slide rail 4 is horizontally arranged inside the frame. The solar panel 2 of the power supply device is installed on both sides of the support frame 3's outer shell, providing continuous power support even without an external power source. The solar panel works in conjunction with the lithium battery 10 installed inside the support frame 3 to ensure sufficient power even without sunlight. The control device and the battery 10 are installed together inside the pulley assembly's outer shell, forming an integrated structure that facilitates system maintenance and wiring connections. The battery provides power to components such as the microcontroller. The self-locking slide rail 4 has a stop-and-go function, locking its current position during pulley operation to adapt to the need for adjustments in different directions during conductor erection. The fixing ring 1 is used to anchor the entire device to the construction tower. In use, power is first supplied through the solar panel 2 and the battery to activate the magnetic levitation device 5 and the control device. The magnetic levitation device 5 is used to achieve non-contact support of the anchor rope, and the control device is used to monitor the tension and position of the anchor rope 8 in real time and adjust the magnetic levitation device 5.

[0023] Preferably, the magnetic levitation device 5 includes an annular housing 501 mounted on the top of the base 6. Eight coil groups 502 are evenly arranged on the inner diameter of the housing 501. A magnetic core 503 is fixedly connected to one end of each coil group 502 away from the annular housing 501. A flexible partition 505 is also fixedly connected to the side of the magnetic core 503. The magnetic core 503 and the flexible partition 505 are connected to form an annular plate. Figure 2As shown, the magnetic levitation device 5 in this embodiment consists of eight coil groups 502, four on the top and four on the bottom. The upper coils are labeled A1, A2, A3, and A4, and the lower coils are labeled B1, B2, B3, and B4. Each coil group 502 has an inner diameter of 20 mm and an outer diameter of 40 mm, with a current range of 0 to 10 A. The microcontroller adjusts the current direction and intensity of each coil group 502 to achieve dynamic adjustment of the segmented magnetic field, thereby controlling the position and tension of the anchor rope 8. When the anchor rope 8 deviates, the microcontroller increases the current intensity of the coil group on the opposite side (e.g., A3 and A4) and decreases the current intensity of the coil in the direction of deviation (e.g., A1 and A2) based on the feedback data from the data acquisition and monitoring device (measurement accuracy of ±0.1 mm and detection range of ±10 mT), corrects the magnetic field distribution, and ensures that the anchor rope is in a balanced state.

[0024] Preferably, the data acquisition and monitoring device includes Hall elements 504 spaced on the magnetic core 503. The device also includes a clamp-type tension sensor 9 fixed to the end of the anchor rope via a screw adjuster 901 and a buzzer 7 mounted on the support frame 3. The Hall elements 504, clamp-type tension sensor 9, and buzzer 7 are all electrically connected to the control device. In this embodiment, four groups of Hall elements 504 are distributed on the four magnetic cores 503 in the magnetic levitation device, specifically mounted on the end of the magnetic core 503 furthest from the coil group 502, for monitoring the displacement of the anchor rope position. The buzzer 7 emits an alarm signal when the anchor rope deviates or the tension is abnormal, with an alarm sound reaching 90dB (suitable for noisy environments). The buzzer is triggered by a control signal from the microcontroller to ensure timely warnings in abnormal situations. The clamp-type tension sensor 9 is fixed to the end of the anchor rope via the screw adjuster 901 for real-time monitoring of the anchor rope tension (measurement range 0-5000N, accuracy ±0.1%).

[0025] Preferably, the clamp-type tension sensor 9 includes a protective housing 903, and a plurality of tension sensing units 902 are disposed within the inner diameter of the protective housing 903. The clamp-type tension sensor 9 clamps the anchor rope 8 via a screw adjuster 901. In this embodiment, during use, the tension sensing units 902 transmit the measurement signal to the control device for real-time data processing and feedback. The protective housing 903 adopts an IP65 protection rating design to adapt to outdoor environments, prevent external damage, and ensure stable operation of the sensor in harsh environments. The tension sensor can be selected from the Futek LCM300 series load unit, which has high accuracy and good anti-interference ability, and can work stably under high load and complex environments.

[0026] Preferably, the anchor rope 8 includes a core material 801, a magnetic wrapping layer 802 is provided on the outer periphery of the core material 801, and a protective layer 803 is provided on the outer periphery of the magnetic wrapping layer 802.

[0027] Preferably, the core material 801 is aramid fiber, the magnetic coating layer 802 is made of iron-nickel-cobalt alloy, and the protective layer 803 is a fluororubber coating. In this embodiment, the core material 801 of the anchor rope 8 is made of aramid fiber, providing high tensile strength; the magnetic coating layer 802 is made of Fe-Co-Ni alloy with a composition of 50% Fe, 30% Co, and 20% Ni, a magnetic permeability μ≥5000, a saturation magnetic induction intensity Bs≥1.8T, and a coupling efficiency with the electromagnet's magnetic field of over 85%; the protective layer 803 is a fluororubber coating with good weather resistance.

[0028] Preferably, the flexible partition 505 is made of high-strength polymer material, and its length is customized according to actual needs. It is mainly used to isolate the vibration and interference during the operation of the anchor rope, reduce the interference to the magnetic field, and ensure the stability of the system.

[0029] The working principle of this application is as follows: First, the system initializes. The solar panel 2 starts supplying power, and the battery 10 provides auxiliary power, activating the magnetic levitation device and control system. The Hall element 504 and the clamp-type tension sensor 9 complete initialization and self-test, recording the initial position and tension value of the anchor rope. Based on the initial state, the system sets the coil group 502 to a uniform magnetic field mode to ensure the anchor rope runs smoothly in the initial stage. Then, real-time monitoring begins. The Hall element 504 continuously monitors the running position of the anchor rope to determine if there is any deviation. At the same time, the clamp-type tension sensor 9 detects the tension change of the anchor rope in real time and transmits the data to the microcontroller for analysis. The microcontroller makes a comprehensive judgment on the state of the anchor rope based on the set tension and position range. When the Hall element 504 detects a deviation in the anchor rope position, the microcontroller controls the coil group 502 to adjust the current direction and intensity. The system adjusts the anchor rope position first, then adjusts the tension, ensuring the stability and safety of the anchor rope operation. When the clamp-type tension sensor 9 detects an abnormal tension, the microcontroller adjusts the anchor rope's force state by regulating the electromagnet current intensity. The system prioritizes correcting the anchor rope position, then adjusts the tension to ensure the stability and safety of the anchor rope operation. After the anchor rope position and tension return to normal, the system records the operating status and maintains the current magnetic field distribution. If a continuous abnormality is detected, the buzzer 7 emits an alarm signal to remind the construction personnel. Real-time data can be uploaded to the remote control center through the data transmission module to achieve remote monitoring and construction command. During operation, the system prioritizes adjusting the anchor rope position, corrects the offset, and then adjusts the tension to ensure the stability and safety of the anchor rope operation during construction. The control device can transmit anchor rope tension and position data to the construction command center through the remote monitoring module, supporting real-time monitoring and operation command issuance.
