When carrying out safety engineering, it is necessary to protect the safety engineering through safety protection devices. After searching, the patent with the authorization publication number CN217841129U discloses a protective device for safety engineering, which belongs to the field of protective equipment, including a fixed seat, an expansion screw is installed inside the fixed seat, a support column is fastened and inserted inside the fixed seat, a limiting ring is fixedly welded to the outside of the lower end of the support column, a sphere is fixedly welded to the upper end of the support column, a fixing block is fixedly welded to the side of the support column, and the inside of the fixing block is threadedly connected with a hexagon socket screw. The protective device for safety engineering can improve the stability of the support column and the guardrail by fixing the fixed seat to the ground with the expansion screw to prevent the guardrail from being pushed down, and can facilitate and quickly install the support column and the guardrail by inserting the lower end of the support column into the fixed seat, thereby improving the installation efficiency; the design of the detachable support column and the guardrail can facilitate transportation and reduce the labor of manually carrying the overall fixed protective structure, and can facilitate the installation of the sleeve and the guardrail by inserting the connecting block into the fixed block and turning and tightening the hexagon socket screw. The above patent has the following shortcomings: during installation, one worker is required to carry the guardrail, and another worker is required to install the hexagon socket screws for installation, which is not convenient. For this reason, we propose a protective device for safety engineering. Utility Model Content
