Safety lock for high-altitude operation device and use method of safety lock

Abstract

The invention provides a safety lock for a high-altitude operation device and a use method of the safety lock. The safety lock comprises a columnar lock body (1) and a sliding block (4), wherein the columnar lock body (1) is provided with a vertical through hole (2) and an inclined groove (3); the sliding block (4) is arranged in the inclined groove (3) and is matched with the inclined groove (3); when the safety lock is in use, a block head (40) of the sliding block (4) in the safety lock is upwards and fixedly arranged on an outer wall (8) of the high-altitude operation device, a traction suspension rope (7) and / or a guiding suspension rope (7) of the high-altitude operation device are / is vertically arranged in the through hole (2) of the safety lock in a penetrating manner; under the normal condition, the safety lock is only a guiding device of the traction suspension rope (7) and / or the guiding suspension rope (7); when the high-altitude operation device falls suddenly and rapidly, gravity is generated, and the sliding block is thrown out reversely to clamp the suspension rope (7) in the through hole (2), so that the purpose of locking the high-altitude operation device is achieved. The safety lock provided by the invention has the advantages of simple structure, low cost, good safe and reliable effects, convenience in installation and use, long service life, no maintenance, high universality, great promotion and application value and wide market prospect.

Description

technical field [0001] The invention relates to a safety protection device, in particular to a safety lock for a high-altitude operation device and a using method thereof, belonging to the technical field of high-altitude operation safety protection. Background technique [0002] With the development of social economy, high-altitude operations have become a normal state, including the use of high-altitude operation devices such as aerial work baskets or elevators for the transportation of personnel and materials, the construction, decoration, and cleaning of high-rise buildings. However, no matter how the aerial work equipment develops and how skilled the workers are in operating skills, working at heights is always an extremely dangerous job. Therefore, it cannot be overemphasized to do a good job in the safety protection of working at heights. [0003] Serious accidents of high-altitude operations include the sudden and rapid fall of high-altitude operation devices. Once s...

Problems solved by technology

The internal structures of these two kinds of safety locks are relatively complicated, including a large number of return springs and bearings. Therefore, the failure rate is high and the reliability is low. Falling impurities will cause the lock body to be stuck, and emergency braking cannot be performed at critical moments, losing the safety protection function; moreover, the calibers of these two safety locks are usually fixed, and must be installed on the matching sling to be able to To play a role, a sling that is too thin cannot be locked, and a sling that is too thick cannot pass through the lock body. The versatility is not strong, and installation and maintenance are inconvenient
