I. Introduction
With the rapid development of social production, the demand for electricity in urban construction and industry production is increasing, leading to a continuous increase in the laying of power grids in the power industry. At the same time, in order to ensure the stability and safety of energy supply in the power grid, post maintenance and protection work of the power grid is essential. Therefore, in the post maintenance and protection work of the power grid, how to ensure the safety of personnel's lives while maintaining stable energy supply and carrying out maintenance of transmission lines is one of the key research contents in the current power industry [1]. Flat ladder, also known as insulation ladder, is a specialized climbing tool for power engineering, telecommunications engineering, electrical engineering, hydropower engineering, etc. It can ensure that personnel on it are not harmed by the current of transmission lines to the maximum extent possible. However, in recent years, with the increase in the number of transmission lines, the workload and difficulty of line maintenance have become increasingly high. As one of the necessary tools for live work, platforms are bulky and difficult to move, which poses certain risks. Therefore, the application efficiency and adaptability of traditional flat ladders in modern transmission line maintenance have gradually decreased [2].
