Description

Climbing soft ladder anti-fall combination safety protection tool

technical field

The utility model relates to a combination safety protection tool for climbing a soft ladder against falling from a high altitude, and belongs to the technical field of maintenance of overhead power transmission lines.

Background technique

Overhead transmission lines operate in the field all the year round, and are greatly affected by the natural environment, climate, geography and their own high voltage, and often have some defects that affect safe operation. In order to ensure safe operation, the line must be overhauled to eliminate these defects. In order to ensure the uninterrupted power supply of the line, live work is often used to overhaul the line. The ladder method to enter the equipotential is a common method for workers to enter the strong electric field, that is, the workers perform corresponding work by climbing the insulated ladder to the live wire.

The traditional soft ladder method enters the equipotential. Generally, the staff carries a circular transmission rope with a pulley to climb to the pole tower, hangs the pulley on the wire with an insulating operating rod, and the ground staff uses the circular transmission rope to transfer the soft ladder to the wire. place, and then hang the wire wheel of the ladder on the wire. The ladder climbing staff climbs the ladder to work on the wire, and the personal protection in the climbing process is a transfer rope installed on the head of the ladder in advance. The tackle and ladder head used in the traditional ladder method to enter the equipotential cannot be closed before the staff climbs the ladder. Factors such as the movement of the ladder and the vibration of the wires when the staff is working at heights can easily cause the pulley and the ladder head to fall off. During the climbing process, the ladder is very unstable and often shakes, which may easily cause the climber to miss, stumble and accidentally fall. Once the ladder climber accidentally misses or falls, the impact force when the climber suddenly falls is much greater than the arm strength of the person pulling the protective rope on the ground.
