Anti-falling device and anti-falling method

Abstract

The invention provides an anti-falling device and an anti-falling method. The anti-falling device comprises a guide rail, a self-locking device, a safety belt and the like, wherein the guide rail is provided with at least one clamping seat which protrudes the matrix surface of the guide rail, the upper end face of the clamping seat is a clamping face clamped and braked with a clamping block of the self-locking device, and the height of the clamping seat is gradually reduced from the clamping face of the upper end to the part of the lower end protruding the matrix of the guide rail; and the self-locking device comprises the clamping block and a body, wherein the clamping block is movably connected with the body through a rotating pin shaft, the clamping block is provided with a clamping head, the clamping block can rotate by using the rotating pin shaft as a center, and the clamping head extends out of the bottom surface of the body to realize locking braking with the clamping seat on the guide rail. The anti-falling device has better stress performance, and has safer and more reliable braking performance between the guide rail and the self-locking device; and by using the device and the method, normal action and overhauling operation of an operator are not affected at the same time of protecting the safety of the operator.

Description

technical field [0001] The invention relates to a fall prevention device and a fall prevention method, in particular to a fall prevention device and a fall prevention method applied to high-altitude operations on poles and towers. Background technique [0002] my country's power transmission line towers are composed of cement poles and iron towers, and the height is basically more than 20 meters. The installation, maintenance, and maintenance of the lines require operators to go up and down the towers and carry out high-altitude operations. Reliable fall protection device can provide safety guarantee for operators. [0003] The anti-fall device is a protective product used for workers at high places on the tower to safely hang in the air after falling during climbing, moving and working. At present, the anti-fall devices commonly used in high-altitude operations are guided-type anti-fall devices. The interaction between them creates a braking effect. [0004] The traditio...

Problems solved by technology

[0007] In addition, when the operator is working on a pole tower, when it is necessary to enter from one guide rail to another guide rail in different directions, it is usually necessary to install a diverter between the two guide rails in different directions, and the diverter in the prior art can only be used for a specific angle. Or the conversion of direction, or has a complex structure and is not conducive to the operation at high altitude, has certain limitations
