The UAV traction device is fixed at the end of the UAV, and is mainly used for traction and auxiliary assembly and disassembly of the hanging line pulley device. Its special fan-shaped structure wind plate with holes can well suppress the deflection problem caused by high-altitude wind, ensuring that the UAV traction hanging line pulley device always maintains a stable posture, and is not easy to rotate or shake, so as not to affect the assembly and disassembly efficiency and accuracy. The wire-hanging pulley device is mainly used as a temporary high-altitude lifting point for traction and transfer of high-altitude objects. Its special high-altitude installation method and special anti-falling structure can ensure safe and quick installation and disassembly at high altitude, and avoid safety accidents such as high-altitude falling of the wire-hanging pulley device during high-altitude transfer operations. At the same time, the special installation and disassembly method, using its center of gravity transfer characteristics, easily realizes the use of drones for high-altitude installation and disassembly operations, filling the gap in the automatic installation of high-altitude lifting points for high-altitude live operations.

[0025] The opening angle between the guide arm 2 and the lower end of the right side wall of the main body 1 is 60 degrees.

[0026] The ball spring plunger 8 is matched with the first positioning hole 6 and the second positioning hole 7 respectively.

[0027] The lower end of the locking and anti-falling device 4 is cross-staggered with the guide arm 2 and is used to clamp the ground wire 16 .

[0028] The side wall of the mounting tube 9 and the side wall of the fixing rod 10 are both provided with latch holes, the two latch holes are matched, and the fixing rod 10 is fixedly connected to the mounting tube 9 via the latch.

[0029] A drone towing and releasing device 15 is arranged inside the hook 14 . The drone towing and releasing device 15 includes an insulating small thin rope and a wind-fixing wing plate. A grounding wire 16 is arranged between the main body 1 and the locking and anti-falling device 4 .

[0030] The UAV towing device adopts a large-area wind-fixing plate with wind holes under the V-shaped hook, which can effectively suppress the device's swing and non-orientation caused by the wind force of the device retracting the blades under the UAV and the wind force at high altitude. It adopts a flexible double-rope hook with the function of suppressing the device's swing, and the hook length can be flexibly adjusted. The overall structure is light and light, and it is easy to store;

[0031] The wire hanging pulley device adopts a gravity self-locking mechanism combined with a spring plunger positioning pulley device, which has an anti-fall locking function. During operation, the center of gravity will not be unstable and it will not fall out of the high-altitude wire due to the shaking of the wire or the device itself, causing a high-altitude fall accident. The pulley is swung 120 degrees and hooked and placed, combined with an extended guide arm, so that the pulley inlet is large enough when entering and exiting the high-altitude ground wire, and it is also convenient for observation, and its hanging and disassembly efficiency and hanging and disassembly accuracy are greatly improved; an extended guide hook structure is adopted, and the extended guide hook is placed a distance outside the wire.

[0032] Working principle:

[0033] First, install the traction rope 13 on the rope pulley device 11, connect the drone traction release device 15 to the drone, and then manually hook the transmission line ground wire special hanging wire pulley device into the drone traction release device 15. The drone drives the device to rise, and the locking anti-falling device 4 automatically opens. At the same time, the torsion spring 5 is compressed, and the ball spring plunger 8 is positioned at the first positioning hole 6. At this time, the device is in an open state, and the drone drives the device to rise above the ground wire. Operate the drone to place the guide arm 2 on the ground wire 16. Under the guidance of the guide arm 2, slowly lower the drone so that the ground wire 16 enters the main body along the guide arm 2. The drone transfer release device 15 continues to descend, and the drone lifting force decreases. At this time, the torsion spring 5 automatically resets, the locking anti-falling device 4 automatically closes, and the ball spring plunger 8 is positioned at the second positioning hole 7. At this time, operate the drone to disengage the drone traction release device 15 from the hook, and the transmission line ground wire special hanging wire pulley device is installed. After the operation is completed, the drone is operated to drive the device to rise, unlock the locking anti-falling device 4, and under the guidance of the guide arm 2, the device is raised as a whole to above the grounding wire until the device is detached from the grounding wire, completing the removal of the device.
