The top ends of the guide rods 11 are provided with a lifting frame 12, and the lifting frame 12 is slidably connected with the guide rods 11. A limiting component is arranged inside the lifting frame 12 to limit and fix between the lifting frame 12 and the guide rods 11;

[0027] Top frame 2, the top frame 2 is fixedly installed at the top end of the lifting frame 12. On the front and rear sides of the top end of the top frame 2, guardrails 21 are fixedly installed. At both ends of the guardrails 21, there are ladders 22, and the ladders 22 are slidably connected with the guardrails 21. A clamping column component is arranged inside the ladders 22 to limit and fix between the ladders 22 and the guardrails 21.

[0028] In a preferred embodiment, as shown in Figures 5-6As shown, the limiting component includes a connecting shaft 14 fixedly installed at the bottom end of the lifting frame 12. At both inner ends of the connecting shaft 14, there are limiting rods 19. A number of limiting grooves 13 matching the limiting rods 19 are formed on the outer surface of the guide rod 11. A collar 17 is sleeved on the outer surface of the connecting shaft 14. Adjusting grooves 15 are formed on the outer surfaces at both ends of the connecting shaft 14. The inner wall of the collar 17 passes through the adjusting grooves 15 and is fixedly connected to the outer surface of the limiting rod 19. Then, the collar 17 is moved along the adjusting grooves 15 to drive the limiting rod 19 to disengage from the limiting groove 13 on the guide rod 11, releasing the limitation of the lifting frame 12. Then, the lifting frame 12 can be moved upward or downward along the guide rod 11.

[0029] In a preferred embodiment, as Figure 6 shown, a pin 18 is inserted into the outer surface at the top end of the collar 17. A through hole 16 is formed on the outer surface of the connecting shaft 14, and the bottom end of the pin 18 passes through the top end of the connecting shaft 14 and is inserted into the interior of the through hole 16. The pin 18 is pulled upward to make the bottom end of the pin 18 disengage from the through hole 16, releasing the limitation on the collar 17.

[0030] In a preferred embodiment, as Figures 1-2 shown, an adjusting rod 25 is provided at the inner top end of the ladder 22. Mounting seats 27 are fixedly installed at both ends of the adjusting rod 25 on the inner wall of the ladder 22, and both ends of the adjusting rod 25 are rotatably connected to the mounting seats 27. A sliding groove 23 is formed on the inner wall of the guardrail 21. Sliders 26 are fixedly installed on the outer surfaces on both sides of the ladder 22, and the sliders 26 are slidably connected to the guardrail 21 through the sliding groove 23. The ladder 22 is lowered along the guardrail 21, and the lowered length of the ladder 22 can be adjusted according to the height of the top frame 2.

[0031] In a preferred embodiment, as Figures 3-4 shown, a clamping post 28 is arranged inside the slider 26, and the clamping post 28 is slidably connected to the slider 26. A clamping groove 24 matching one end of the clamping post 28 is formed on the inner wall of the sliding groove 23. One end of the clamping post 28 is fixedly connected to a connecting rod 29, and the connecting rod 29 is threadedly connected to the adjusting rod 25. The adjusting rod 25 at the top end of the ladder 22 is rotated. The adjusting rod 25 is threadedly connected to the connecting rod 29. During the rotation, the clamping post 28 will be pushed outward through the connecting rod 29, so that the clamping post 28 is inserted into the clamping groove 24 on the inner wall of the sliding groove 23 to fix the ladder 22.

[0032] The working principle of the present utility model:

[0033] Referring to the attached drawings of the specification Figures 1-6, during use, workers can climb onto the top frame 2 through the ladder 22 on one side. Then, pull the ladder 22 upward. The sliders 26 on both sides of the ladder 22 will slide upward along the chute of the guardrail 21. When the slider 26 reaches the top of the chute 23, rotate the adjusting rod 25 at the top of the ladder 22. The adjusting rod 25 is threadedly connected to the connecting rod 29. During the rotation process, the clamping post 28 will be pushed outward through the connecting rod 29, so that the clamping post 28 is inserted into the clamping groove 24 on the inner wall of the chute 23 to fix the ladder 22 and use it as a protective structure at both ends. When it needs to be lowered, the limit of the ladder 22 can be released first, and the ladder 22 can be lowered along the guardrail 21. The length of the lowered ladder 22 can be adjusted according to the height of the top frame 2. When the construction height needs to be adjusted, first pull the pin 18 upward so that the bottom end of the pin 18 disengages from the through hole 16 to release the limit of the collar 17. Then move the collar 17 along the adjustment groove 15 to drive the limit rod 19 to disengage from the limit groove 13 on the guide rod 11 to release the limit of the lifting frame 12. Then move the lifting frame 12 upward or downward along the guide rod 11 to adjust the height of the top frame 2. After the adjustment is completed, reset the limit rod 19 and insert it into the corresponding limit groove 13. Finally, push the pin 18 downward and insert it into the through hole 16 for limit fixation.
