Safety device

Abstract

The invention discloses a safety device which comprises a guide rail and a safety device body, wherein the guide rail is arranged on a to-be-climbed rod; a groove extending along the length direction is formed in the guide rail; the cross section of the groove vertical to the length direction is open toward one side; the safety device body comprises a moving part inserted into the groove and moving along the length direction, a braking part cooperating with the moving part for braking on the inner and outer sides of the opening, and a connecting part for connecting a safety rope; the braking part is articulated with the moving part through a first articulated shaft; a zigzag bulge for clamping the guide rail with the moving part is arranged on the peripheral wall of the braking part close to the first articulated shaft; a torsional spring for keeping the braking part in a trend of being pressed toward the moving part is arranged on the first articulated shaft; and one end of the connecting part is articulated with the braking part, and the other end is glidingly connected with the moving part. Through the clamping of the guide rail by the braking part and the moving part as well as the cooperation between the zigzag bulge and the guide rail, the friction force between the safety device body and the guide rail is relatively strong, and the safety in use is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric power auxiliary equipment, in particular to a safety device. Background technique [0002] Electricity is sent to users by means of overhead lines, cables and other media. Overhead lines need to be erected on poles and towers. The maintenance and repair of overhead lines need to be carried out on poles. The lowest pole is at least 8 meters high. This kind of high-altitude work is easy to happen. Falls are limited to life-threatening. [0003] A typical safety device is a speed difference protector, which is manufactured by using the principle of speed difference when falling. However, there is a limitation of high hanging and low use every time it is used, and each time it is necessary to climb to a higher working place to fix the speed difference protector before it can be used normally. However, there is no protective measure in the process of fixing the speed difference protector, so this ki...

AI Technical Summary

Problems solved by technology

However, there are restrictions on high-hanging and low-hanging use each time, and each time you need to climb to a higher working place to fix the speed difference protector before it can be used normally

However, there is no protective measure in the process of fixing the speed difference protector, so this kind of safety device has great potential safety hazards when used
