Anti-falling device for steel pipe pole operation of power transmission lines

Abstract

The invention belongs to the technical field of operating maintenance of power transmission lines, and particularly relates to an anti-falling device for steel pipe pole operation of power transmission lines. The anti-falling device is arranged on a binding type safety belt base body, a steel pipe pole on the safety belt base body is carried by a worker to an operation position, a locked detectiondevice is unlocked and winds across angle iron so as to be tied, and a hanging ring of a falling brake device is hung at a high position. A warning message can be given out if a safety belt is not tied, and an insertion head can be pushed inwards automatically if the insertion head is not fastened. When the worker falls, a central control monitoring unit can provide a brake signal to make the falling brake device to act rapidly, mechanical brake is triggered if an electric fault happens, and thus dual protection is achieved. The work conditions of all components are fed back to ground monitoring personnel in the whole process. The anti-falling device has the advantages that the brake distance is short, noise is avoided in the operation process, reminding and monitoring functions can be achieved, and the anti-falling device is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of operation and maintenance of power transmission lines, and in particular relates to a fall prevention device for steel pipe poles of power transmission lines. Background technique [0002] In the power system, among various accidents caused by various factors such as unsafe behaviors of people, unsafe conditions of objects, poor environment, and ineffective supervision and management, the top three accidents according to statistics are electric shock, high-altitude accidents, etc. Drop and mishandling. It is obvious that falling accidents caused by improper protection during high-altitude operations are one of the most important casualties every year. Nowadays, people are paying more and more attention to the prevention of accidents, and working at heights is full of potential dangers, and various factors may cause falling accidents. Therefore, it is very necessary for workers working at heights to make...

AI Technical Summary

Problems solved by technology

The safety belt is generally buckled on the steel pipe around you when operating at high altitude, but with the continuous increase of the voltage level, the height of the steel pipe pole is increasing day by day, and the construction personnel easily forget this operation during heavy operations, or for the convenience of movement Deliberately not buckle it, or fail to fasten it completely, and the supervisor below is too far away, there is a blind spot in the field of vision, and it is difficult to find out in time

As the second line of defense, the safety rope is hung on a high place. In order to facilitate work, the safety rope generally reserves a large margin.

However, most of the existing fall arresters use differential speed protection, which are heavy and noisy in operation. When construction workers make large lateral movements, they will suddenly lock up and interfere with normal work.
