[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Please see Figures 1-7 This utility model provides a technical solution:

[0028] A fall-prevention guide rail climbing device suitable for cement poles includes a cement pole 1, a guide rail 2, a guide rail climber 3, and a mounting clamp 4. The guide rail 2 is fixedly connected to the cement pole 1 through the mounting clamp 4, and symmetrical guide rail climbers 3 are provided on the outside of the guide rail 2.

[0029] The mounting fixture 4 includes two arc-shaped mounting plates 5, each with mounting holes at both ends. Both ends of the two arc-shaped mounting plates 5 are fitted with fastening bolts 6. Each end of the two arc-shaped mounting plates 5 clamps a bracket 7. The bracket 7 has symmetrical limiting grooves inside, with limiting posts 8 slidingly arranged inside the limiting grooves. A return spring 9 is sleeved on the outside of the limiting post 8. One end of the return spring 9 is fixedly connected to the side wall of the limiting post 8, and the other end is fixedly connected to the inner wall of the limiting groove. The front side wall of the bracket 7 has symmetrical strip-shaped openings. Pull rods 10 are fixedly installed on the front side walls of both limiting posts 8. The front ends of both pull rods 10 pass through the strip-shaped openings and extend to the front end of the bracket 7.

[0030] The guide rail climber 3 includes a climber body 11. The inside of the climber body 11 is provided with symmetrical climber grooves 12. The upper end of the climber body 11 is provided with a climber cover 13. The right side wall of the climber body 11 is provided with an installation port. Inside the installation port, a pedal crank arm 14 is rotatably provided via a crank arm pivot 19. The right end of the inner wall of the climber groove 12 is rotatably provided with symmetrical crawling rollers 15. The upper end of the installation port is provided with a fixing groove. The inside of the fixing groove is fixedly provided with a crank arm spring 16. The upper end of the pedal crank arm 14 is provided with a pedal 17. The upper side wall of the pedal 17 is fixedly provided with symmetrical fixing belts 18.

[0031] The guide rail climber 3 is installed on the guide rail 2. The device is connected and fixed to the worker's feet by the fixing belt 18. When the worker lifts his feet, there is a gap between the pedal crank arm 14 and the guide rail 2. The crawling roller 15 moves upward close to the guide rail. When the worker presses down his feet, the top of the pedal crank arm 14 will press against the guide rail 2 to prevent the worker from sliding down. By alternately lifting and pressing down with both feet, the worker can climb to the top of the cement pole.

[0032] The side wall of the guide rail 2 is provided with evenly arranged limiting holes, the limiting post 8 is inserted into the limiting holes, and the side wall of the guide rail 2 is provided with reinforcing connection holes at both ends of the limiting holes.

[0033] The guide rail 2 and the mounting clamp 4 are made of aluminum alloy and stainless steel, which are not easily damaged or deformed during use.

[0034] The lower end of the crank arm spring 16 is connected and fixed to the upper side wall of the pedal crank arm 14. When the pedal crank arm 14 is subjected to downward pressure, the lower end of the left side wall of the pedal crank arm 14 contacts the side wall of the guide rail 2. When the foot presses down on the pedal crank arm 14, the left end of the pedal crank arm 14 rotates around the crank arm pivot 19, thereby making the left end of the pedal crank arm 14 engage with the guide rail 2. When the downward pressure of the foot is released, the pedal crank arm 14 returns to horizontal under the pulling force of the crank arm spring 16.

[0035] Both crawling rollers 15 are rubber rollers, which increase the friction between them and the guide rail 2 and prevent slippage.

[0036] Working principle:

[0037] By holding the lever 10, press the limiting post 8, which is fixed to the lever 10, back to completely retract the head of the limiting post 8 that extends out of the guide rail 2; while keeping the limiting post 8 pressed down with one hand, hold the guide rail climber 3 with the other hand and align the climber slide 12 with the guide rail 2, then insert the guide rail climber 3 from below the guide rail 2; after the guide rail climber 3 is inserted into the guide rail 2, release the lever 10, and the limiting post 8 will automatically return to its original position due to the action of the return spring 9, preventing the guide rail climber 3 from extending out of the guide rail 2. After disengaging from guide rail 2, the guide rail climber 3 is installed. The operator secures their foot to the pedal 17 using the fixing belt 18. By lifting their foot, a gap is created between the pedal crank arm 14 and guide rail 2, and the crawling roller 15 is pressed against guide rail 2, allowing the operator to move upward.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
