[0002] Construction safety is a safety issue that will be encountered in engineering construction in every industry. The construction of construction safety protection equipment is conducive to reducing safety hazards in construction and ensuring the safety of workers in construction. In the existing bridge construction technology, most of the protective devices are installed on the side of the bridge to prevent construction workers from falling from the side. However, in the actual construction process, workers may slip and fall from the gap between the steel bars at the bottom of the bridge. In this case, the workers fall directly into the sea, which may endanger their lives. Therefore, it is very necessary to design a device that can prevent workers from falling from the bridge and climb back to the bridge deck. Summary of the invention
