Temporary anti-drop device for transmission lines

Abstract

A temporary fall prevention device for power transmission lines, comprising a first bottom plate and a second bottom plate vertically arranged side by side, fast grasping devices are installed on both ends of one side of the first bottom plate, and a control center and a power supply are installed on one side of the second bottom plate , the first bottom plate and the second bottom plate are installed with a horizontal low-speed torque holding device, and the top of the first bottom plate and the second bottom plate is fixedly installed with a manipulator pick-and-place device. The positive effects of the present invention are: the present invention is portable, and the anti-falling device can be articulated through remote control without climbing the tower, which replaces the traditional manual work, saves time and effort, and only one person can complete the articulated work of the anti-falling device. While improving the mounting efficiency, it also reduces the operating risk of the staff and ensures the personal safety of the maintenance staff. The invention is applicable to the hooking operation of the anti-falling device of steel pipe towers, towers with a height of more than 30m, and towers with a line of 220kV and above.

Description

technical field [0001] The invention relates to the technical field of anti-drop devices for power line maintenance poles and towers, in particular to a temporary anti-drop device for power transmission lines. Background technique [0002] In order to ensure the normal operation of transmission lines, inspection and maintenance is one of the essential tasks. Transmission line towers are generally equipped with spikes or ladders for high-altitude workers to climb up and down the tower along the spikes and ladders. During the process of getting on and off the tower or horizontal displacement, accidents are prone to fall from high altitudes. The hands are released at the same time, the body loses balance, and the foot falls backward; the second is that the operator steps on the ground during the climbing process, and the hand cannot bear the sudden load of body weight and falls out of the foot nails, resulting in a vertical fall; the third is the operation During the shifting ...

Transmission line towers are generally equipped with spikes or ladders for high-altitude workers to climb up and down the tower along the spikes and ladders. During the process of getting on and off the tower or horizontal displacement, accidents are prone to fall from high altitudes. The hands are released at the same time, the body loses balance, and the foot falls backward; the second is that the operator steps on the ground during the climbing process, and the hand cannot bear the sudden load of body weight and falls out of the foot nails, resulting in a vertical fall; the third is the operation Falling from high altitude due to sudden damage of foot nails or ladder damage during the shifting process of personnel on the pole tower

In order to ensure the safety of the maintenance personnel, it is usually necessary to install safety ropes on the electric towers to be repaired in advance. However, at present, the installation of safety ropes and other anti-fall devices is usually done manually, and there is a relatively large risk. Ensure the personal safety of staff
