Problems solved by technology

[0002] At present, most substation main substations do not have a place to hang the safety belt. When the maintenance personnel work on the transformer, the safety belt has no place to hang it. They can only be hung on the parts of the transformer body or the porcelain vase nearby. This kind of The practice violates the power safety work regulations, and there is a huge potential safety hazard

Abstract

The invention discloses a hand-cranking type anti-falling safety device, including a hand-cranking control device installed on an inner wall face of a wall of one side of a transformer and a fixed device installed on an inner wall face of a wall of the other side of the transformer. The hand-cranking control device and the fixed device are oppositely arranged; the hand-cranking control device includes a roller, a control box, a deflection gear, a hand rocker, a lock control handle, a first cable and a buckle with a female spring; the first cable is wound on the roller, one end of the first cable is connected with the deflection gear, and the other end is connected with the buckle with the female spring; the fixed device includes a fixed hook and a second cable; and one end of the second cable is fixed on the fixed hook, and the other end is connected with the buckle with the female spring. The hand-operated type anti-falling safety device is installed on the inner wall faces of the walls of both sides of the transformer, and can be used for hanging a safety belt, thereby protecting safety of transformer maintenance personnel.

Description

technical field [0001] The invention relates to a hand-operated anti-falling safety device. Background technique [0002] At present, most substation main substations do not have a place to hang the safety belt. When the maintenance personnel work on the transformer, the safety belt has no place to hang it. They can only be hung on the parts of the transformer body or the porcelain vase nearby. The practice violated the power safety work regulations, and there was a huge potential safety hazard. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a hand-operated anti-falling safety device, which is installed on the inner walls of both sides of the transformer and can be used to hang safety belts to protect the safety of transformer maintenance personnel. [0004] The technical solution to achieve the above purpose is: a hand-operated anti-fall safety device installed on the inner walls of the wall...
