A Self-Inspecting Hanging Rod Locking Mechanism, Locking Frame, and Self-Locking Fall Arrester Device for Transmission Towers
Abstract
The rapid advancement of power grids stands as a pivotal indicator of technological progress and industrialization in modern society. Overhead line operations, characterized by high difficulty and risk, are prone to accidents such as high-altitude falls and electric shocks, which significantly undermine the safety and economic efficiency of power systems. Particularly in the context of smart grid construction, more stringent requirements have been imposed on overhead line operations. With maintenance tasks becoming increasingly refined and workloads escalating, there is an urgent need to optimize and upgrade existing fall arresters to enhance their intelligence, operational convenience, and safety reliability, thereby providing comprehensive safeguards for maintenance operations. This paper presents a self-inspecting hanging rod locking method, a locking frame, and a self-locking fall arrester tailored for transmission towers. Integrating UAV technology, recognition and control technology, and fall arrester technology, this equipment offers all-round safety protection for high-altitude power grid workers.
