Aerial operation parallel movement anti-falling self-locking device

Abstract

The invention discloses an aerial operation parallel movement anti-falling self-locking device. The device comprises an elastic clamp, pulleys and a sleeve; the elastic clamp includes a fixed part and rotating parts; the fixed part is a symmetric structure; the upper end of the fixed part is mounted on a cross bar; the lower end of the fixed part horizontally moves on a portal frame through the pulleys mounted on two sides; two ends of the fixed part are connected with the rotating parts; one rotating part is provided with a sleeve through a spring; mounting grooves are respectively formed in the rotating parts; springs are mounted in the mounting grooves; the end diameters of the mounting grooves are larger than the diameters of the rotating parts; a buckle is mounted in the sleeve, and is a ring; and the inner diameter of the ring is smaller than the diameters of the end parts of the mounting grooves. The device is skillful in structure, small in size, light in weight and convenient for operation, effectively protects aerial operation staff, and guarantees safety of the aerial operation.

Description

technical field [0001] The invention relates to the field of equipment maintenance, in particular to a parallel-moving high-fall self-locking device for high-altitude operations. Background technique [0002] There are many kinds of power operations. Working on the frame in the substation, such as retracting and releasing wires, changing porcelain bottles, measuring zero value and salt density, removing bird nests, installing bird-proof baffles, etc., all need to move in parallel on the frame. In this process, to make maintenance operators safely move parallel on the structure to reach the work site, the traditional method is to use seat belts, but the safety belts need to be untied when moving, and the protection is lost. The State Grid Corporation of China has experienced many high-altitude workers falling accidents during the movement process. Therefore need a kind of movable anti-falling device, make high-altitude worker be in the protection, guarantee the safety of hig...
