[0030] Furthermore, one of the pulleys between the left plate and the right plate is set as a driving pulley 8, and the wheel axle 22 of the driving pulley 8 extends out of the bearing 9 on the side plate of the inverted U-shaped base 19 and is rotatably connected.

[0031] Furthermore, the concave cam 24 is configured as a cylindrical wheel, and the end surface of the cylindrical wheel is provided with successively rising step surfaces in the circumferential direction, and the braking distance is adjusted by the step surfaces of different heights.

[0032] The lower end of the other side plate of the connecting slide rod 25 side plate of the above-mentioned inverted U-shaped base 19 is connected to a hook 39 inclined toward the outside, which is convenient for the inverted U-shaped base 19 to be hung on the cable. A safety pin 38 is provided at the upper end of the safety door, and a safety hole is provided on the side plate of the inverted U-shaped base 19 corresponding to the safety pin 38. The safety pin 38 is inserted into the safety hole to fix the safety door, thereby further ensuring the stability of the connection between the inverted U-shaped base 19 and the cable.

[0033] When the present invention is in use, first observe whether the pulley needs to be positioned. When positioning is required, adjust the distance between the brake blocks 21 in the brake mechanism on the left and right plates of the inverted U-shaped base 19 according to the diameter of the cable. The adjustment method is: after the folding handle 31 is flipped, the folding handle 31 drives the connecting ear plate 33 to rotate, and then drives the concave cam 24 to rotate. After rotating to the required height of the concave cam 24, rotate the inner convex column 45, and rotate the inner convex column 45 to contact the end face of the concave cam 24. Finally, flip the folding handle 31 back to its original position, and then the drone is connected to the hanging ring through the connecting ring 46. The drone lifts the hanging ring and moves it above the inverted U-shaped base 19. The drone drives the hanging ring to move to the position of the spiral rod 4, and aligns the vertical steel wire 47 of the hanging ring with the The screw rod 4 is in contact with the bolt rod. Due to the effect of the light rod 5, the vertical steel wire 47 can be prevented from crossing the two sides of the bolt rod. The vertical steel wire 47 can only be fixed on one side of the bolt rod. After being fixed on one side of the screw rod 4, the screw rod 4 is driven to rotate by starting the screw motor 28. While the screw rod 4 rotates, the vertical steel wire 47 of the hanging ring is driven to move toward the hanging hook 3. When the hanging hook 3 penetrates into the hanging ring, the hanging ring is lifted upward so that the horizontal steel wire 48 of the hanging ring is inserted into the hanging hook 3, so that the drone can lift the inverted U-shaped base 19 through the hanging ring. After lifting, the inverted U-shaped base 19 is moved to the top of the cable in the air by the drone, and the position of the cable is matched between the two side plates of the inverted U-shaped base 19, and the drone is moved down. After the drone moves down The cable is inserted between the inverted U-shaped bases 19, the security door 41 is opened, the cable enters the inverted U-shaped base 19 and contacts the pulley, and is stuck between the brake blocks 21 on the left and right sides. At this time, the sensor 1 is under pressure and transmits a signal to the controller 36. The controller 36 turns on the flashlight 2, indicating that the inverted U-shaped base 19 has been hung in. Then, after manually climbing the power supply tower or the cable, the maintenance operation is carried out. At the same time, the inverted U-shaped base 19 can be further fixed by the safety rope on the safety belt seat 6, and the security door 41 is fixed by inserting the safety pin 38 into the safety hole. When the pulley needs to slide from one power supply tower to another, the folding handle 31 is flipped, and the inner convex column 45 is moved up to disengage from the concave and convex column, and then the concave and convex column is moved in. The cable is rotated to a low height, and then the brake flap 37 is expanded outwardly under the action of the expansion spring, the brake block 21 is not connected to the cable, and then the towing motor 13 is clamped on the inverted U-shaped base 19, the driving shaft 11 of the towing motor 13 is connected to the motor interface 10, the driving motor is started, and the driving motor drives the driving pulley 8 to rotate, and then slides on the cable to complete the required transfer work. The above-mentioned brake mechanism can ensure the stability between the inverted U-shaped base 19 and the cable. At the same time, one of the pulleys is set as the driving pulley 8, and the active towing action can be achieved by the towing motor 13. Moreover, since a hanging ring and an auxiliary hanging mechanism are provided, it can be ensured that the drone can easily hang the hanging ring into the hanging hook 3 through the hanging ring. Due to the above-mentioned structure,It has the advantages of simple structure, good installation effect, high installation efficiency, high safety, and fixed-point maintenance.
