Centrifugal self-locking device for anti-falling rail

Abstract

The invention discloses a centrifugal self-locking device for an anti-falling rail, and relates to the technical field of high-altitude operation protection. The centrifugal self-locking device for the anti-falling rail comprises a first box body, a second box body, a connecting assembly, a centrifugal assembly, a triggering assembly, a cam assembly and two guide assemblies, wherein the centrifugal assembly comprises a speed measuring wheel shaft, two speed measuring wheels and two centrifugal blocks; the two speed measuring wheels are fixed to the two ends of the speed measuring wheel shaft respectively and make contact with the anti-falling rail; the two centrifugal blocks are hinged to the two sides of the middle of the speed measuring wheel shaft respectively; the cam assembly comprises a cam shaft and a cam; the cam is fixedly arranged on the cam shaft in a sleeving mode; a limiting groove is formed in the cam shaft; the triggering assembly comprises a triggering rod and an elastic stretching part; the triggering rod is rotatably installed on the second box body; one end of the triggering rod is clamped in a limiting groove; and the other end of the triggering rod extends to the side, close to the anti-falling rail, of the speed measuring wheel shaft. The device solves the anti-falling problem under extreme special working conditions such as synchronous falling and the like, and effectively guarantees the safety of high-altitude operation personnel.

Description

technical field [0001] The invention relates to the technical field of high-altitude operation protection, in particular to a centrifugal self-locking device for an anti-fall rail. Background technique [0002] High-voltage overhead transmission lines are the backbone channels of power transmission. In order to ensure the high reliability of the power grid, it is necessary to manually climb the towers to conduct regular inspections of the transmission lines in order to detect and eliminate hidden dangers in time. Manual climbing towers are high-altitude operations, and the safety of the tower climbers must be guaranteed. Therefore, the current anti-fall track has become an indispensable device for the planning and construction of high-voltage transmission lines, and the self-locking device used in conjunction with the anti-fall track has become a key component to ensure the safety of tower climbers. [0003] At present, the self-locking single circular eccentric wheel is co...
