The invention discloses an anti-falling device which comprises a slide rail and an anti-falling apparatus. The anti-falling apparatus is arranged on the slide rail, first slide grooves are formed in the slide rail, slide bars which are matched with the first slide grooves are arranged on the side walls of the anti-falling apparatus and are penetratingly arranged in the first slide grooves, first limit plates are arranged on the slide bars, a first connecting rod is arranged on the anti-falling apparatus, a connecting hole is formed in the first connecting rod, a plurality of support frames arearranged on a side wall of the slide rail, a mounting cavity is arranged on the anti-falling apparatus, and a limit rod which can move along the inside of the mounting cavity is arranged on the anti-falling apparatus and is matched with the support frames.
Description
technical field [0001] The invention belongs to the technical field of aerial work devices, and in particular relates to a fall prevention device. Background technique [0002] A fall arrestor, or fall arrest device, is usually incorporated into a harness worn by a person working at a higher height; a fall arrester reduces the injuries that may occur when a worker falls from his or her work platform. [0003] A fall arrester disclosed in Chinese patent CN103991769A can effectively prevent the cage from falling accidents. When the hanging cage suspension breaks and falls freely, the fall arrester starts to act and gradually increases the braking force. Make the cage brake smoothly, so as to ensure the safety of the goods and the integrity of the equipment; but the braking stroke required by this device is long, which is not suitable for personnel to use, and the user has fallen too far before the fall arrester plays a braking role , no protection for personnel.
