Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cantilever operating platform. Background Art

[0002] The cantilever operation platform is a transfer station for transporting building materials from the lower floor to the upper floor during the construction of high-rise buildings. Its basic structure is to fix two beams extending from the building body to a certain floor slab, and set a bottom plate on the extended section of the two beams as a load-bearing cantilever platform. A box is set above the bottom plate to receive the building materials lifted by the crane. After the building materials are loaded into the box, they are taken away by workers for use. However, the building materials are heavy, and the bottom plate is far away from the floor slab, so it is time-consuming and laborious for workers to carry them.

[0003] In order to solve the above problems, the utility model patent with application number 202321955345.3 adopts a movable bottom plate to carry the building materials on the cantilever platform over a short distance. After the building materials are loaded onto the bottom plate, the bottom plate is moved to the floor, or the building materials that need to be transported upward are placed on the bottom plate, and then the box is moved to the outer end of the beam.

[0004] However, due to the weight of the building materials themselves, when moving a box full of building materials, the box itself will generate a large inertia. If no buffer device is provided, when the box stops moving, it will impact the overall structure of the cantilever platform, increasing the risk. Utility Model Content

[0006] Among them, a plurality of wheels are arranged at the bottom of the base plate, and a strip groove is arranged at the top of the frame beam along the length direction, and the wheels cooperate with the strip groove.

[0007] Wherein, a wire ring is fixedly arranged on the frame beam.
