They are usually made of high-strength steel or concrete and can range in height from tens to hundreds of meters to ensure that the blades of the wind turbines can rotate at high altitudes where the wind is strongest. The wind tower supports the nacelle, which contains core components such as the gearbox and generator, as well as the hub and blades, which together capture wind energy and convert it into electrical energy. The tower must be designed to withstand strong winds, extreme weather and the torque generated by the rotation of the blades. With the development of technology, wind towers have become more efficient and environmentally friendly, and are an important part of the renewable energy field.

When the maintenance personnel pull the pull rope 9 through the pull ring 7, the connecting rod 1504 rotates accordingly, thereby pushing the first folding plate 1503 and the second folding plate 1510 to cooperate with each other. The first folding plate 1503 is rotatably connected with the movable link 1305 so that the movable link 1305 slides on the second slide rail 1502. At this time, the moving movable link 1305 drives the lower clamping block 1301 to tighten and pull the safety rope 11 downward. Then the movable link 1305 returns, and the lower clamping block 1301 is loosened and returned to realize the running rope operation, thereby realizing the tightening and loosening action of the clamping block 1301 on the safety rope 11. The second folding plate 1510 is rotatably connected with the limit frame 1507 and cooperates with the setting of the spring 1505 to ensure that during the return process of the movable link 1305, the clamping block 1301 can be accurately loosened and returned to the initial position, thereby completing the entire running rope operation. At the same time, when the safety rope 11 slips, the maintenance personnel,Pull the pull rope 9 hard to drive the lower clamp block 1301 to tighten the safety rope 11 downward to lock the safety rope 11.
