Description

Technical Field

[0001] This invention relates to the field of safety protection cage technology, specifically a double-cage safety protection cage for high-altitude operations on steel beams. Background Technology

[0002] In the field of construction and installation engineering, current safety measures for high-altitude operations mostly employ reinforced steel cages. These cages are typically single-sided, which presents several drawbacks in actual construction. For example, they have low load-bearing capacity, usually only able to support one person at a time, resulting in low work efficiency. Furthermore, due to the inherent mechanical properties of steel bars, which are tensile but not bending-resistant, the cages are prone to deformation during use, hindering their reuse. In addition, the confined space inside the cage makes operation difficult and unstable, with significant swaying with worker exertion, posing a considerable safety hazard. This is particularly true when workers are operating at heights on steel beams, where the single-sided cage is less suitable.

[0003] However, existing protective cages are only suitable for I-shaped or rectangular steel beams, not for circular steel beams, and cannot meet the usage requirements of different types of steel beams. Summary of the Invention

The end of the support block supports the surface of the second support plate, sharing the force of the screw and preventing the second support plate from loosening. The first moving plate can descend in the lifting groove, and the steel beam is fixed to the surface of the base plate through two through bolt holes. Attached Figure Description
