When the driving assembly drives the first locking assembly to act, the first locking assembly slides to engage with the first limiting assembly, thereby locking the base plate 4. The second locking assembly is symmetrically arranged on both sides of the driving assembly, and the base plate 4 is provided with a second limiting assembly located on both sides of the driving assembly, and the second limiting assembly can be engaged with the second locking assembly. When the driving assembly moves to a preset height, the second locking assembly engages with the second limiting assembly to lock the driving assembly. The preset height is set in combination with the sliding distance of the first locking assembly to ensure that the second locking assembly and the second limiting assembly are engaged after the first locking assembly and the first limiting assembly are engaged.
[0042] In some embodiments, such as Figure 3 As shown, the driving assembly includes a fixed column 11 and a sliding plate 12. The fixed column 11 is provided on the top of the bottom plate 4, and the fixed column 11 passes through the sliding plate 12. The sliding plate 12 is slidably connected to the fixed column 11. The first locking assembly is movably connected at both ends of the sliding plate 12, and the second locking assembly is connected at both sides of the sliding plate 12.

[0044] Further, such as Figure 1As shown, the first limit assembly includes a limit column 2 and a slot 3. A plurality of limit columns 2 are provided at both ends of the support frame 1. Specifically, four limit columns 2 are used in this embodiment. The four limit columns 2 are symmetrically arranged at both ends of the support frame 1.

A plurality of slide grooves 9 are provided inside the bottom plate 4. Specifically, in this embodiment, two slide grooves 9 are provided inside the bottom plate 4. The position of the slide groove 9 corresponds to the position of the limit column 2. The clamping column 10 is slidably installed in the slide groove 9. The first end of the clamping column 10 at least partially passes through the top of the bottom plate 4, and the second end of the clamping column 10 faces the clamping groove 3 and corresponds to its position.

[0047] like Figure 4 and Figure 5 As shown, when the sliding plate 12 is pressed toward the bottom plate 4, the sliding plate 12 slides downward along the fixed column 11 and squeezes the first spring 17. The sliding plate 12 pushes the clamping column 10 to slide outward in the corresponding slide groove 9 through the rotating rod 16 until the end of the clamping column 10 is engaged in the corresponding clamping groove 3. When all four clamping columns 10 are engaged in the corresponding clamping groove 3, the bottom plate 4 is locked. At the same time, the sliding plate 12 drives the L-shaped plate 13 and the clamping plate 14 to move downward outside the fixed column 11 until the L-shaped plate 13 and the clamping plate 14 are engaged and connected with the connecting frame 15 to ensure that the sliding plate 12 is locked.
[0048] In some embodiments, such as Figure 6As shown, the adjustment assembly includes a fixed block 18, a rotating shaft 20, a motor 19, a connecting piece 21, a connecting pipe 22, a hanging rope 23, a fixed lug plate 24 and a conveying roller 25. The tops of both ends of the support frame 1 are both installed with fixed blocks 18, and motors 19 are installed on the fixed blocks 18. The fixed blocks 18 are rotatably connected with the rotating shaft 20. The output end of the motor 19 is connected to the end of the rotating shaft 20, and the motor 19 is used to drive the rotating shaft 20 to rotate.

[0050] Furthermore, a second spring 8 is disposed on the outer sleeve of the telescopic rod 6 , one end of the second spring 8 is connected to the bottom of the base plate 4 , and the other end of the second spring 8 is connected to the top of the connecting plate 5 .
[0051] Embodiment The implementation principle of a scaffolding anti-fall device is as follows:
[0052] This device is arranged under the scaffolding to ensure that the scaffolding is located above the base plate 4. When the scaffolding suddenly falls due to special circumstances, it will drive the base plate 4 to fall synchronously. By controlling the rotation speed of the output end of the motor 19, the suspension rope 23 drives the base plate 4 to fall at a limited speed, which effectively reduces the falling speed of the base plate 4. Then, the sliding plate 12 is pressed, and the sliding plate 12 slides downward along the fixed column 11 and squeezes the first spring 17. The sliding plate 12 drives the rotating rod 16 to push the corresponding clamping column 10, so that the clamping column 10 slides outward inside the slide groove 9 until the end of the clamping column 10 slides out of the slide groove 9 and engages with the clamping groove 3.
[0053] At the same time, the sliding plate 12 drives the L-shaped plate 13 and the clamping plate 14 to move downward. After the clamping column 10 is engaged with the clamping slot 3, the L-shaped plate 13 and the clamping plate 14 cooperate to engage the connecting frame 15, and form an embracing lock on the connecting frame 15, further fixing the sliding plate 12 and the clamping column 10 connected thereto. The bottom plate 4 is fixed in time to prevent the bottom plate 4 from falling further to ensure the safety of the passengers. Furthermore, the motor 19 is turned off to stop the rope 23 from rotating. Through the double locking method, the scaffolding can effectively stop falling in the event of an accident, thereby improving the safety of the scaffolding.
[0054] A buffer assembly is provided between the base plate 4 and the bottom of the support frame 1. The telescopic rod 6, buffer pad 7 and second spring 8 in the buffer assembly can synchronously reduce shock and buffer the generated impact, greatly reduce the impact of the collision and collision generated after the fall on the operator, and provide buffer protection for the operator in time, minimize the instantaneous impact force on the operator, and effectively reduce the risk of physical injury to the operator due to the instantaneous impact force.
[0055] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
