The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] The utility model provides an automatic anti-falling device for power tower operation, such as Figure 1-5 As shown, the automatic anti-falling device for power tower operation includes: a support rod 1; a protection box 2 slidably arranged on one side of the support rod 1; a group of connecting plates 3 slidably arranged in the protection box 2; a gear 4 rotatably installed on any one of the connecting plates 3; a one-way bearing 5 assembled on the other connecting plate 3, the one-way bearing 5 is connected to the output rod of the gear 4; a rack 6 fixedly installed on one side of the support rod 1, the rack 6 is meshed with the gear 4; and an adjustment mechanism arranged on the protection box 2 for adjusting the gear 4.

[0027] In this embodiment, when using this device, the support rod 1 is first installed on one side of the climbing frame of the iron tower, so as to facilitate subsequent maintenance personnel to climb. When the maintenance personnel need to climb, the hook 22 is first hung on the safety rope of the maintenance personnel, so that the safety rope 20 is connected to the maintenance personnel, and then the maintenance personnel climb on the climbing frame. When climbing, the safety rope 20 drives the protection box 2 to slide, so that the protection box 2 slides along the support rod 1. At the same time, the gear 4 in the protection box 2 rotates along the rack 6, and the climbing is smoother;

[0028] The one-way bearing 5 rotates freely in one direction but is locked in the other direction. Therefore, when the maintenance personnel fail to step firmly and fall out of the climbing frame, the one-way bearing 5 is automatically locked, thereby fixing the gear 4, making the gear 4 stuck in the rack 6 and unable to rotate, thereby fixing the protective box 2 and ensuring that the maintenance personnel will not fall.

[0029] In a further preferred embodiment of the utility model, the support rod 1 is arranged in a T shape, an L-shaped plate 7 is fixedly installed on one side of the protection box 2, a guide wheel 8 is fixedly installed on the L-shaped plate 7, and the guide wheel 8 is in sliding contact with the support rod 1.

[0030] In this embodiment, when the protection box 2 slides along the support rod 1, the L-shaped plate 7 drives the guide wheel 8 to slide along the support rod 1, thereby providing auxiliary guidance for the protection box 2 to ensure its smooth sliding.

[0031] In a further preferred embodiment of the utility model, the adjustment mechanism includes: a positioning plate 9 fixedly mounted on one side of the connecting plate 3, the positioning plate 9 slidably extending out of the protective box 2; a positioning groove 10 provided on the positioning plate 9; a fixing block 11 fixedly mounted on one side of the protective box 2; a positioning rod 12 slidably arranged on the fixing block 11, the positioning rod 12 being adapted to the positioning groove 10; and a positioning mechanism arranged on the protective box 2 for fixing the positioning rod 12.

[0032] In this embodiment, when the maintenance personnel need to climb down from the tower, they first take out the positioning rod 12 to slide the positioning rod 12 away from the fixed block 11, then slide the positioning plate 9, so that the positioning plate 9 drives the connecting plate 3 to slide, and the connecting plate 3 drives the gear 4 to slide away from the rack 6. Then the maintenance personnel hang the lock on the protective clothing worn on their bodies on the fixing ring 19 to protect the maintenance personnel from falling. Then the maintenance personnel climb and hang the lock on the corresponding fixing ring 19 by themselves. At the same time, since the gear 4 is away from the rack 6, when the maintenance personnel climb, the protective box 2 slides down along the support rod 1 according to its own gravity.

[0033] In a further preferred embodiment of the utility model, an elastic rope 13 is fixedly installed at the bottom of the protective box 2, and the bottom end of the elastic rope 13 is fixedly connected to the positioning rod 12. A guide rod 14 is fixedly installed inside the protective box 2, and the guide rod 14 is slidably connected to the connecting plate 3.

[0034] In this embodiment, the connecting plate 3 is guided by the guide rod 14, so as to facilitate the subsequent movement of the connecting plate 3. At the same time, it is also beneficial to the return processing of the gear 4. The elastic rope 13 is connected to the positioning rod 12 to prevent the positioning rod 12 from being lost, ensuring that the positioning rod 12 will not be separated from the protective box 2, which is better for use.

[0035] In a further preferred embodiment of the utility model, the positioning mechanism includes: a connecting rod 15 fixedly installed on one side of the protective box 2; a connecting plate 16 slidably installed on the connecting rod 15; a fixing rod 17 fixedly installed on one side of the connecting plate 16, and the fixing rod 17 is slidably connected to the positioning rod 12; a compression spring 18 sleeved on the connecting rod 15, and the two ends of the compression spring 18 are respectively fixedly connected to the mounting plate of the connecting rod 15 and the connecting plate 16.

[0036] In this embodiment, when the positioning plate 9 needs to be fixed, the connecting plate 16 is first moved so that the connecting plate 16 drives the fixing rod 17 to slide, and the connecting plate 16 slides along the connecting rod 15, thereby stretching the compression spring 18, and then the positioning rod 12 is inserted into the positioning groove 10, so as to limit the positioning plate 9. At the same time, the slot of the positioning rod 12 is located on one side of the fixing rod 17. The connecting plate 16 is loosened to shrink the compression spring 18 and bounce the fixing rod 17 into the slot, thereby limiting the positioning rod 12. The limiting is relatively quick.
