It can maintain the safety of workers and is used as an operating frame and a protective frame to bear the weight of itself, safety nets, railings and workers. However, how to avoid uneven load distribution during the use of scaffolding and thus cause the scaffolding to tilt is a problem that needs to be solved urgently.

[0003] After searching, the announcement number CN220014411U discloses an anti-tilt lifting scaffold, which belongs to the technical field of scaffolding.

The driving component 2 includes a forward and reverse motor 21 fixedly installed on the outside of the rail groove 11. The driving component 2 also includes a synchronous rod 22, one end of the synchronous rod 22 is fixedly connected to the output end of the forward and reverse motor 21, and the synchronous rod 22 is connected to the rail groove 11 through the forward and reverse rotation of the forward and reverse motor 21. Two groups of opposite threads are arranged on both sides of the outer surface of the synchronous rod 22, and the synchronous rod 22 is located at the opposite threads on both sides. The first support assembly 3 is arranged, and the first support group Part 3 includes a slide 31, each slide 31 matches the surface thread of the synchronization rod 22, the first support assembly 3 also includes a main support plate 32, the main support plate 32 is fixedly connected to the bottom of the slide 31, and the second support assembly 4 is symmetrically arranged on both sides of the bottom of the support platform 1. The second support assembly 4 includes an auxiliary support plate 43 that extends outward synchronously with the movement of the main support plate 32. This design solves the problem that the prior art only provides auxiliary support designs for the two sides of the long sides of the scaffolding, while synchronous auxiliary support cannot be performed on the two sides of the short sides of the scaffolding, which results in a limited contact range between the device and the bottom surface. At the same time, this design requires manual disassembly and assembly of the auxiliary support assembly before and after each use, which makes the construction progress more cumbersome.

[0026] See also Figure 5 The second support assembly 4 also includes a fixed column 41, which is fixedly connected to the bottom of the support platform 1. The second support assembly 4 also includes two groups of limit blocks 431, which are symmetrically fixedly connected to both sides of the auxiliary support plate 43. The auxiliary support plate 43 and the limit blocks 431 are integrated and match the shape of the side slide groove at the bottom of the support platform 1. This design can avoid the position displacement of the auxiliary support plate 43 during the extension and retraction process.

[0027] See also Figure 5The second support assembly 4 also includes an upper support 42, which is fixedly connected to the top of the auxiliary support plate 43. The second support assembly 4 also includes a spring ring 411, which is elastically connected to the fixed column 41 and the middle of the upper support 42. Through this design, when the main support plate 32 is recovered to the bottom of the support platform 1 under the drive of the forward and reverse motors 21, the auxiliary support plate 43 located on the long side of the support platform 1 can be synchronously recovered to the bottom of the support platform 1 under the action of the spring ring 411.

[0028] See also Figure 2 and Figure 3 A lifting assembly 5 is also provided on the top of the supporting platform 1. The lifting assembly 5 includes a base 51, which is fixedly connected to the top of the supporting platform 1. The lifting assembly 5 also includes a cylinder 52, which is arranged on the top of the base 51, and the fixed end of the cylinder 52 is fixedly connected to the top of the base 51.

The lifting assembly 5 also includes a connecting rod 53, the middle part of the connecting rod 53 is fixedly connected to the telescopic end of the cylinder 52, and the four ends of the connecting rod 53 are fixedly connected to the support columns 54. Before extending from the bottom of the supporting platform 1 through the auxiliary supporting plate 43 and the main supporting plate 32, the support columns 54 can be driven downward by the connecting rod 53 through the telescopic end of the cylinder 52 until the bottom of the supporting platform 1 is separated from the bottom. This design can avoid the auxiliary supporting plate 43 and the main supporting plate 32 from contacting the bottom surface and generating friction when they extend from the bottom of the supporting platform 1.

[0029] The working principle and use process of the utility model are as follows:

[0030] Before the auxiliary support plate 43 and the main support plate 32 extend from the bottom of the support platform 1, the support column 54 can be driven downward by the connecting rod 53 through the telescopic end of the cylinder 52 until the bottom of the support platform 1 is separated from the bottom. This design can prevent the auxiliary support plate 43 and the main support plate 32 from contacting the bottom surface and generating friction when they extend from the bottom of the support platform 1. After the above work is completed, the forward and reverse motors 21 are started so that the output ends of the forward and reverse motors 21 drive the synchronous rod 22 to rotate. At this time, the two groups of slide seats 31 respectively threadedly connected to the threads on both sides of the synchronous rod 22 synchronously drive the main support plates 32 to move in opposite directions until the two groups of main support plates 32 extend from the short sides of the two sides of the support platform 1. At the same time, when the main support plates 32 move During the movement, the oblique cross-section side will synchronously squeeze the oblique cross-section side of the auxiliary support plate 43, so that the two groups of auxiliary support plates 43 extend from the long side of the bottom of the support platform 1 during the movement of the main support plate 32. Through this design, the auxiliary support plate 43 and the main support plate 32 can further expand the contact area between the support platform 1 and the bottom surface as a whole, thereby avoiding tilting during operation. Similarly, starting the forward and reverse motor 21 to reverse can make the two groups of main support plates 32 quickly retract to the bottom of the support platform 1. In particular, when the main support plate 32 is retracted to the bottom of the support platform 1 under the drive of the forward and reverse motor 21, the auxiliary support plate 43 located on the long side of the support platform 1 can be synchronously retracted to the bottom of the support platform 1 under the action of the spring coil 411.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
