Crawling ladder safety protection device capable of automatically crossing cross rod

Abstract

The invention discloses a crawling ladder safety protection device capable of automatically crossing a cross rod, and belongs to the field of crawling ladder devices. The crawling ladder safety protection device comprises a hoop ring, a stop lever and a rope clamp activation mechanism. The hoop ring is provided with a first hoop ring opening end and a second hoop ring opening end; the second hoop ring opening end is provided with a blocking part; the stop lever is arranged between the first hoop ring opening end and the second hoop ring opening end; and the second end of the stop lever abuts against the bottom face of the blocking part. The rope clamp activation mechanism comprises a first spring, a safety rope, a blocking column and an outer side hook; and the top end of the safety rope penetrates through the side wall of the second hoop ring opening end and is connected with the outer side hook. According to the crawling ladder safety protection device, the personal safety of workers can be guaranteed continuously, and meanwhile, the device can move upwards / downwards along with automatic crossing of cross rod obstacles by the workers. The device is clear in stress, simple in structure, light, flexible, economical and practical, and can be arranged at different protection parts according to needs. An external power supply is not needed, and the safety of falling workers is completely protected by a mechanical principle, so that the safety and the reasonability are achieved.

Description

technical field [0001] The invention belongs to the field of ladder devices, in particular to a ladder safety protection device that can automatically cross a cross bar. Background technique [0002] Workers must wear safety belts when working at heights exceeding 2m, and workers need to untie the safety rope buckle to change positions during the climbing process, resulting in the need to frequently change the position of the rope buckle when moving, increasing invalid working time. In addition, when the tower crane driver climbs the tower, and the deep well worker climbs down to the deep well, there is a lack of effective protection measures for the tight connection between the worker and the ladder. Contents of the invention [0003] The purpose of the present invention is to provide a ladder safety protection device that can automatically cross the cross bar to solve the problem that workers need to untie the safety rope buckle to change the position during the climbing...
