Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a power climbing anti-fall steering device. Background Technology

[0002] With the rapid development of technology, human demand for electricity is constantly increasing. At the same time, the number of high-altitude power transmission stations is also steadily growing. The main body of the transmission station is equipped with multiple maintenance guide rails, and each guide rail is equipped with a fall arrestor. The fall arrestor is equipped with an opening and closing buckle. Construction workers connect their protective clothing to the fall arrestor through the opening and closing buckle. The fall arrestor slides along the maintenance guide rail according to the climbing speed of the maintenance personnel. The maintenance personnel climb to a high altitude and carry out maintenance on the main body of the transmission station.

[0003] When existing steering gears are connected to external guide rails, they are mostly fixed with bolts and nuts. Each time they are disassembled and assembled, an external wrench is required, which is very inconvenient. At the same time, when adjusting the steering of the internal guide rails, existing steering gears require multiple rotations of the intermediate rail to adjust its position so that the inspection rail aligns with the intermediate rail. The operation of adjusting and fixing the position of the guide rails is also quite complicated, resulting in low practicality. Utility Model Content

An external guide rail 13 is inserted into the inside of the connecting sleeve 2. The limiting slide plate 7 and the connecting rack 9 are inserted into the inside of the external guide rail 13. A fixing seat is provided on the side of the connecting sleeve 2. One end of the fixing seat is rotatably connected to a limiting baffle 14. The outer surface of the connecting sleeve 2... The base 1 is provided with a positioning block 15, the position of which is adapted to the position of the limiting baffle 14. There are four connecting sleeves 2, and each connecting sleeve 2 has two upper limit slides 7, connecting racks 9, large gears 4 and small gears 5, which are staggered. The base 1 is rotatably connected to a support shaft 16. One end of the support shaft 16 is provided with a rotating disk 17. The outer surface of the rotating disk 17 is provided with a steering guide rail 18. The end of the support shaft 16 away from the rotating disk 17 is provided with a fixing plate 19. The fixing plate 19 is slidably connected to an adjusting ring 20. One end of the adjusting ring 20 is provided with a fixed... Positioning plate 21 is slidably connected to the outer surface of support shaft 16. A first spring 22 is provided on the outer surface of positioning plate 21. The end of the first spring 22 away from positioning plate 21 is provided on fixed plate 19. A limit post 23 is provided on the end of positioning plate 21 away from the first spring 22. A limit hole 24 is opened inside the base 1. The position of the limit hole 24 is adapted to the position of the limit post 23. A positioning baffle 25 is provided on the outer surface of the base 1. There are four positioning baffles 25, and their positions are adapted to fixed plate 19. Two baffles form a group, and the two groups are distributed at a 90-degree angle to each other.

[0030] To ensure that the electric climbing fall protection steering device can be easily installed and removed from the external guide rail 13, and to facilitate quick steering and positioning, as shown in the attached document... Figure 1-8As shown, this application adopts the following structure, which is configured by the cooperation of connecting shaft 3, large gear 4, small gear 5, adjusting rack 6, connecting rack 9, control handle 12, supporting shaft 16, rotating disk 17, steering guide rail 18, positioning plate 21, adjusting ring 20, fixing plate 19, first spring 22, limiting post 23, and positioning baffle 25. During use, by rotating the limiting baffle 14, the limiting baffle 14 is disengaged from the connecting plate 11 and rotated onto the positioning block 15. Then, by pulling the control handle 12, the adjusting ring 20 is driven to adjust the position. The sliding of the rack 6 drives the large gear 4, connecting shaft 3, and small gear 5 to rotate. Under the action of the connecting rack 9, the two limiting slide plates 7 slide outward, disengaging from the middle connecting groove of the connecting sleeve 2 (under the action of the limiting block 10, when the limiting block 10 on the connecting rack 9 moves to the position of the small gear 5, the limiting block 10 and the small gear 5 limit each other, preventing the limiting slide plates 7 from disengaging from the connecting sleeve 2). Subsequently, the external guide rail 13 is placed into the connecting sleeve 2, and the connecting plate 11 is pushed in the opposite direction, causing the adjustment... The rack 6 slides inward, allowing the limiting slide plate 7 to pass through the external guide rail 13 and insert into the connecting sleeve 2, completing the connection. Then, the limiting baffle 14 is reversed, causing it to engage with the connecting plate 11, limiting the movement of the connecting plate 11 and the adjusting rack 6, thus completing the connection of the external guide rail 13. To disassemble the external guide rail 13, repeat the above steps. When the steering guide rail turns, pull the adjusting ring 20, which in turn pulls the positioning plate 21, compressing the first spring 22 and causing the limiting post 23 to disengage from the limiting hole 24. Then, the rotation... Adjust the adjusting ring 20 until the fixed plate 19 contacts the positioning baffle 25. At this time, the fixed plate 19 and the steering guide rail 18 rotate 90 degrees. Then, release the adjusting ring 20. Under the elastic force of the first spring 22, the limiting post 23 is locked into the corresponding limiting hole 24, completing the guide rail steering adjustment of the steering device. This enables the electric climbing fall protection steering device to facilitate the quick installation and removal of the external guide rail 13 and to facilitate the quick steering operation and positioning of the steering device.
