Description

Technical Field

[0001] This utility model belongs to the field of orifice safety isolation and protection technology, and specifically relates to a hidden linkage retraction kick plate for orifice fences. Background Technology

[0002] In our daily work, we often need to move up and down through access openings. These equipment openings are usually equipped with opening covers. When workers need to move up or down through these openings, the opening covers need to be opened and a safety barrier needs to be erected to ensure the safety of the work in the opening area.

[0003] According to national standards, the isolation fence erected at the opening needs to be equipped with a kickboard of corresponding height. Currently, the common practice is to temporarily install the kickboard or to directly fabricate the kickboard on the fence. However, these methods have the following problems: 1. The erection of temporary kickboards is complicated by the cumbersome material transportation. Materials need to be prepared on the spot each time they are erected. In actual work, these materials are fragile and there will be some consumption each time they are erected and dismantled, which makes the material preparation cumbersome. 2. The kickboards installed directly on the fence are not suitable for fences with concealed openings. The fence posts slide up and down in the foundation. The kickboards in the horizontal direction need to have clearance grooves to ensure the vertical movement of the fence device. This makes it impossible to install the kickboards continuously, which does not meet the corresponding requirements. The existence of the above-mentioned problems restricts the safe and efficient implementation of safety protection measures at the orifice. How to ensure the rapid installation and dismantling and safe operation of the kick plate at the orifice is an urgent problem for our operation and maintenance personnel to solve. Summary of the Invention
