[0024] Reference Figure 1 and Figure 4 As shown in this embodiment: four self-locking casters 2 are symmetrically fixedly mounted on the bottom of the base frame 1. Two studs 3 are threadedly connected to the inner wall of the base frame 1, and a stabilizing plate 4 is fixedly mounted on the bottom of each stud 3. The bottom of the stabilizing plate 4 is provided with anti-slip texture, so that the device can be moved to any location by using the four self-locking casters 2 to carry out aluminum formwork construction work. After arriving at the location of use, the studs 3 can be rotated to make the bottom of the stabilizing plate 4 contact the ground to ensure the stability of the device.

[0025] Reference Figure 2 and Figure 3 As shown in this embodiment: the outer side of the main ladder 6 is fixedly connected to the side of the support frame 5 away from the base frame 1. Two climbing frames 8 are symmetrically fixedly installed on the outer side of the main ladder 6, so that the support frame 5 can provide positioning support for the main ladder 6, ensuring that it will not easily tip over when subjected to stepping force. Moreover, the two climbing frames 8 can be used to grab the hands when stepping on the step bar 7 and the inner wall of the slide 10, improving the safety of climbing.

[0026] Reference Figure 1 and Figure 3 As shown in this embodiment: an adjustment plate 12 is rotatably connected to the side of the foot pedal 11 away from the slide 10. Two guardrails 13 are symmetrically fixedly mounted on the top of the foot pedal 11. The adjustment plate 12 can increase the area when the user steps on it, thereby increasing the operating space during operation and increasing the contact area with the platform to improve stability. The guardrails 13 can play a protective role and ensure the safety of the staff when they are above the guardrails 13.

[0027] Reference Figure 2 and Figure 3As shown in this embodiment: the end of the pull rope 17 away from the connecting ring 16 is fixedly connected to the outer edge of the winding rod 19, and the middle part of the pull rope 17 overlaps the inner wall of the auxiliary wheel 21. There are two connecting rings 16 and two pull ropes 17, and the two connecting rings 16 and pull ropes 17 are symmetrically arranged on the inner wall of the slide 10. This allows the user to turn the handle 20 to drive the auxiliary wheel 21 to wind the pull rope 17 to the outer edge of the winding rod 19, thereby pulling the slide 10 to slide on the inner wall of the slide 9. The height of the device can be adjusted, which facilitates climbing to different heights for aluminum formwork construction.

Two auxiliary wheels 21 are rotatably connected to the inner wall of the side plates. The X-shaped frames can reinforce the support frame 5, and the side plates can position the auxiliary wheels 21 to ensure the stability of the auxiliary wheels 21 when rotating.

[0029] Working principle: When using this device, the four self-locking casters 2 can be used to move the device to any location for aluminum formwork construction. After reaching the location, the studs 3 can be rotated to make the bottom of the stabilizing plate 4 contact the ground, ensuring the stability of the device. Then, depending on the working height, the pull rope 17 can be wound up to the outer edge of the winding rod 19 by turning the crank handle 20 to drive the auxiliary wheel 21. This allows the slide 10 to be pulled to slide on the inner wall of the slide 9, adjusting the height of the device. This facilitates climbing to different heights for aluminum formwork construction. After adjustment, the locking plate 14 can be rotated so that the locking groove 15 at the bottom of the locking plate 14 engages with the outer side of the foot pedal 7, ensuring that it will not fall easily and improving stability. The adjustment plate 12 can increase the area for the user to step on, thereby increasing the operating space during operation and increasing the contact area with the platform, improving stability. The guardrail 13 provides protection, ensuring the safety of the workers when they are above the guardrail 13. Flipping the adjustment plate 12 to the position above the foot pedal 11 can reduce space occupation.
