The maintenance personnel climbs on the L-shaped hanging arm 2 on the other side. When the maintenance personnel climbs to the waist position and is flush with the positioning and protection mechanism 3, the positioning and protection mechanism 3 is adjusted in the opposite direction so that the positioning and protection mechanism 3 and the L-shaped hanging arm 2 are separated. The maintenance personnel adjusts the position of the positioning and protection mechanism 3 with one hand, so that the positioning and protection mechanism 3 moves to the adjacent L-shaped hanging arms 2 on one side that the arm can touch, and adjusts the positioning and protection mechanism 3 with the other hand, so that the positioning and protection mechanism 3 and its position are adjusted in a way of wrapping both hands around, thereby ensuring the stability of the entire system and avoiding the problem of the safety belt slipping due to improper operation or unexpected situations. At the same time, the safety belt is connected to the positioning and protection mechanism 3, which reduces the chance of direct contact between the power pole tower 1 and the safety belt, thereby reducing friction and extending the service life of the safety belt.

[0059] The threaded rod 334 is arranged to be liftable in the direction of the central axis of the worm wheel.

[0060] By adopting the above technical solution, when the handwheel 333 is rotated, the handwheel 333 drives the shaft 332 to rotate, and the shaft 332 drives the worm and the worm wheel to rotate in turn, so that the lifting position of the threaded rod 334 can be adjusted, and the worm and the worm wheel have good self-locking properties, which can effectively prevent the spontaneous movement of the threaded rod 334.

[0065] In a possible implementation, the opposing limit assembly 35 includes:

[0066] The second guide rail 3511 is configured as two and is symmetrically fixed on the partition 32 near the space of the power tower 1. A first slider 3512, a second slider 3513 and a third slider 3514 are movably arranged from bottom to top on the second guide rail 3511;

[0067] A first connecting plate 3515 is fixedly arranged on the second slider 3513 on one side, a first rack 3516 is fixedly arranged on the side of the second slider 3513 on one side close to the partition 32, an upper displacement block 3517 is fixedly arranged on the first rack 3516, and the bottom of the upper displacement block 3517 is fixedly arranged with the third slider 3514, an upper clamping platform 3518 is fixedly arranged on the upper end of the upper displacement block 3517, and the upper clamping platform 3518 is movably arranged in the first through hole 311;

[0069] The rotating shaft 3523 is rotatably arranged at the center position of the partition 32 near the space of the power pole tower 1 and is located between the first rack 3516 and the second rack 3520. A gear 3524 is fixedly arranged on the rotating shaft 3523 near the space of the power pole tower 1. The two sides of the gear 3524 are respectively meshed with the first rack 3516 and the second rack 3520, and the rotating shaft 3523 is fixed to the worm.

[0070] Using the above technical solution, such as Figure 7 As shown, when the gear 3524 rotates clockwise, the first rack 3516 and the second rack 3520 move in opposite directions (move away), the upper shift block 3517 and the upper clamping platform 3518 rise along the second guide rail 3511, and the lower shift block 3521 and the lower clamping platform 3522 descend along the second guide rail 3511; when the gear 3524 rotates counterclockwise, the first rack 3516 and the second rack 3520 move toward each other (approach), the upper shift block 3517 and the upper clamping platform 3518 descend along the second guide rail 3511, and the lower shift block 3521 and the lower clamping platform 3522 rise along the second guide rail 3511.

[0071] In a possible embodiment, the upper card platform 3518 and the lower card platform 3522 have the same structure, and a card slot 35181 is provided on one side close to the L-shaped hanging arm 2. The card slot 35181 is arranged corresponding to the L-shaped hanging arm 2.

[0074] In a possible implementation manner, the inner lateral spacing of the hook ring 361 is equal to the lateral length of the limiting clip 321 .

[0075] Through the above technical solution, when the guide block 344 rises, the hook ring 361 rises, and the distance between the lower end of the hook ring 361 and the limiting strip 321 decreases; when the guide block 344 descends, the hook ring 361 descends, and the distance between the lower end of the hook ring 361 and the limiting strip 321 increases.

[0077] When it is implemented specifically, first hook the safety rope 363 on the clamping ring 362 respectively, then place the positioning protection mechanism 3 between the adjacent L-shaped hanging arms 2 on one side, turn the hand wheel 333 counterclockwise, the hand wheel 333 drives the worm and the worm gear to rotate, the threaded rod 334 rises, the guide block 344 and the limiting slider 343 rise along the first guide rail 342, the hook ring 361 rises, and the distance between the lower end of the hook ring 361 and the limiting clamping strip 321 decreases.
