A first electric cylinder 6 is movably connected between the two sides inside the scissor lift 5. A first guardrail 7 is welded to the front and rear ends of the top of the lifting plate 4. Movable doors 8 are provided on both sides of the top of the lifting plate 4.

[0027] The left and right sides of the lifting plate 4 are not connected to the left and right sides inside the outer frame 1. The lifting plate 4 can move up and down along the inside of the outer frame 1. The first guardrail 7 is symmetrically distributed about the vertical center line of the lifting plate 4. The first guardrail 7 and the movable door 8 are hinged together. The vertical center lines of the outer frame 1, the support plate 3, and the lifting plate 4 coincide. The first electric cylinder 6, the manual controller 13, and the control host 14 are electrically connected to assist in adjusting the construction height of the scaffold.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the first guardrail 7 and the movable door 8 enclose the construction personnel. When the height needs to be adjusted, the first electric cylinder 6 is activated. The retraction of the first electric cylinder 6 will open the scissor lift 5, allowing the lifting plate 4 to rise smoothly, which is convenient for the construction personnel to carry out construction. There are no additional obstructions in front, behind and on both sides, so the operation is not hindered. The first electric cylinder 6, the manual controller 13 and the control host 14 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0029] A housing 9 is fixedly connected to the middle position of the top of the first guardrail 7. A microcontroller 10 is installed inside the housing 9. A laser rangefinder 11 is fixedly connected to the middle position of the top of the housing 9. Speakers 12 are installed on both sides of the top of the housing 9. The tops of the housing 9 and the speakers 12 are flush. The microcontroller 10, the laser rangefinder 11, and the speakers 12 are electrically connected to facilitate the measurement of the actual height of the device from the ceiling.

[0030] Specifically, such as Figure 1 and Figure 3As shown, the laser rangefinder 11 emits a laser upward to measure the distance from the first guardrail 7 to the ceiling, and broadcasts the height in real time through the speaker 12 for the user's reference and adjustment. The microcontroller unit 10, the laser rangefinder 11, and the speaker 12 are electrically connected. This technology is existing technology and will not be described in detail.

[0031] Side brackets 15 are hinged to both sides of the front and rear ends of the outer frame 1. An electric cylinder mounting cylinder 16 is welded to one side of the side bracket 15. A second electric cylinder 17 is installed inside the electric cylinder mounting cylinder 16. The output end of the second electric cylinder 17 is fixedly connected to a push plate 18.

The manual controller 13, the control host 14, and the second electric cylinder 17 are electrically connected to facilitate the formation of stable support.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the side bracket 15 is opened, and the second electric cylinder 17 in the corresponding position electric cylinder mounting cylinder 16 is activated to extend downwards and press against the ground by pushing the floor 18. The four sets of second electric cylinders 17 are independently controlled, which can still form a stable support when the ground is uneven. The manual controller 13, the control host 14, and the second electric cylinder 17 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0033] Working Principle: In use, the scaffolding is first pushed to the construction area. Workers climb to the lifting platform 4 via the side ladder 2 and enter through the movable door 8. The first guardrail 7 and the movable door 8 enclose the workers. When height adjustment is needed, the first electric cylinder 6 is activated. The retraction of the first electric cylinder 6 extends the scissor lift 5, allowing the lifting platform 4 to rise smoothly, facilitating construction work. There are no additional obstructions on the front, back, or sides, ensuring unimpeded operation. As the lifting platform 4 rises, the laser rangefinder 11 emits a laser beam to measure the distance from the first guardrail 7 to the ceiling and announces the height in real time via the speaker 12 for user reference and adjustment. When the lifting platform 4 needs to be raised further, the scaffolding's center of gravity changes, requiring stronger support. The side support 15 is opened, and the second electric cylinder 17 in the corresponding electric cylinder mounting cylinder 16 extends downwards, pressing against the ground through the pusher 18. The four sets of second electric cylinders 17 are independently controlled, ensuring stable support even on uneven ground.
