Anti-falling protecting system and anti-falling protecting method for tower climbing operation of electric transmission line

Abstract

The invention relates to an anti-falling protecting system and an anti-falling protecting method for a tower climbing operation of an electric transmission line. The anti-falling protecting system comprises a safety rope, a rope type bidirectional speed differential mechanism, spiral anti-falling foot pins, a turning anti-falling foot pin and an anti-falling self-locking device, wherein the safetyrope is used for a safety protection hook of an operator; the rope type bidirectional speed differential mechanism is arranged at the column foot of a tower for bidirectional speed differential protection of the safety rope and for forming an anti-falling self-locking protecting point; the spiral anti-falling foot pins are arranged on a tower leg and a cross arm in a spaced manner to form an anti-high-falling suspension supporting point for the operator to grab with hands and pedal with legs and for fixing the safety rope in an anti-falling manner; the turning anti-falling foot pin is used for alleviating the friction force of the safety rope during turning; and the anti-falling self-locking device can be detachably mounted on the safety rope in a sleeving manner, can operate freely alongthe safety rope and can brake in rapid movement and can be locked on the safety rope. By adopting a trackless safety protection technique, the whole tower is anti-falling all around, and the anti-falling protecting system is small in transformation quantity, low in cost and convenient to popularize and apply in a large range.

Description

technical field [0001] The invention relates to the technical field of high-altitude operations on power transmission lines, in particular to an anti-drop protection system and method for power transmission line climbing tower operations. Background technique [0002] my country's transmission lines have a long mileage and many iron towers. The operation safety of transmission lines requires a lot of maintenance work. Tower-climbing maintenance is one of the most important and dangerous tasks in line maintenance work. [0003] Before 2000, limited by technical conditions, basically all the tower climbing maintenance operations of transmission lines were carried out without safety protection measures. High fall and slip accidents occurred from time to time, causing harm to operators, families and society. Big loss. [0004] After 2000, in order to solve the problem of safety protection in the process of climbing towers, China has installed and used iron tower fall prevention...

AI Technical Summary

Problems solved by technology

[0013] The purpose of the present invention is to provide an anti-drop protection system and anti-fall protection method for power transmission line tower climbing operation, so as to solve the problem that a large number of existing iron towers do not have safety protection measures for tower climbing operations, are difficult to transform, and have insufficient anti-fall protection measures for existing safety protection measures. and other problems, this application adopts the trackless safety protection technology, the whole tower is full of anti-falling, the reconstruction project is small, the cost is low, and it is convenient for large-scale promotion and application
