Research and Application of Optimization on Safety Protection Structure for High-Altitude Operations Based on Utility Model

Based on the analysis of the frequent occurrence of falls from heights and the existing problems of traditional safety protection devices such as poor continuity, insufficient flexibility, and weak adaptability, a new type of safety protection structure suitable for high-altitude operations in the field of building construction is designed. By adopting modular rapid assembly connection and centrifugal active locking method, the protection device can always follow the movement of workers and maintain the protection effect, solving the problems of "protection vacuum period" and adaptability to operating scenarios. The research summarizes the advantages of the protection structure, such as strong protection continuity, high locking reliability, and high material utilization rate. It also analyzes that the main reasons for the difficulty in large-scale promotion and application of the structure at this stage include high promotion costs, the need for improvement in operation methods, and incomplete industry standards. Finally, it puts forward improvement ideas towards lightweight, intelligence, and enhanced reliability under extreme working conditions, providing theoretical and practical references for the technical upgrading and system improvement of high-altitude operation safety protection in the construction industry.
