[0002] Scaffolding refers to various supports set up at construction sites for workers to operate and solve vertical and horizontal transportation. It is widely used in various construction operations.

[0003] The scaffold in the related art usually includes a support frame, a hanging basket part is vertically slidably connected in the support frame, and a lifting mechanism for controlling the vertical movement of the hanging basket part is arranged on the support frame. In order to facilitate the movement of the scaffold, self-locking casters are usually added at the four corners of the bottom of the support frame.

[0004] However, when the scaffolding is in use, the self-locking casters need to bear the weight of the supporting frame and the workers. Especially when transporting heavy objects, the self-locking casters are subjected to relatively large pressure. Over time, there is a risk of damage to the self-locking casters, which reduces the service life of the scaffolding and needs to be improved. Utility Model Content

[0010] In a preferred example, the utility model can be further configured as follows: the control component includes a hydraulic cylinder, the tail end of the hydraulic cylinder is fixedly connected to the support frame, and the piston end is fixedly connected to the support plate.

[0011] In a preferred example, the utility model can be further configured as follows: a plurality of limit pins are vertically fixedly connected to the lower surface of the support plate, and when the support plate is lowered, the limit pins can be nailed into the ground, and when the support plate is raised, the lowest end of the limit pins is higher than the bottom of the self-locking caster.

[0012] In a preferred example, the utility model can be further configured as follows: the side wall of the limiting dozer nail is provided with a plurality of soil discharge grooves, and the plurality of soil discharge grooves are arranged at equal intervals along the circumference of the limiting dozer nail, so that the limiting dozer nail can be smoothly inserted into the ground.

[0013] In a preferred example, the utility model can be further configured as follows: the hanging basket portion includes a horizontally arranged receiving frame, a receiving plate is horizontally slidably connected to the receiving frame, a circle of guardrails is fixedly connected at the edge of the receiving plate, the lifting mechanism is used to control the vertical movement of the receiving frame, and a driving member for pushing the receiving plate to move horizontally is provided between the receiving frame and the receiving plate.

This design can reduce the risk of damage to the self-locking casters, thereby increasing the service life of the scaffolding. At the same time, this design can also increase the contact area between the scaffolding and the ground, reduce the pressure, make the scaffolding more stable, and reduce the risk of the self-locking casters sinking into the ground, thereby improving the stability of the scaffolding.

At the same time, a control member 8 for controlling the vertical movement of the support plate 5 is arranged at the bottom of the support frame 1.

[0025] When the scaffold is in use, the four self-locking casters 4 are locked respectively, and then the support plate 5 is controlled to descend through the control member 8, and the support plate 5 is made to abut against the ground. At this time, the support plate 5 and the self-locking casters 4 bear the pressure together, that is, the support plate 5 shares part of the pressure borne by the self-locking casters 4. Of course, the support plate 5 can also be controlled to descend and the self-locking casters 4 are separated from the ground. At this time, the support plate 5 bears all the pressure.

[0026] This design can reduce the risk of damage to the self-locking casters 4, thereby increasing the service life of the scaffolding.
