Description

Rope climbing outage self-locking braking mechanism Technical Field The application relates to the field of braking mechanisms, in particular to a power-off self-locking braking mechanism of a rope climbing machine. Background The climbing machine is used as vertical lifting equipment and is widely applied to the fields of high-altitude operation, fire rescue and the like. At present, the braking technology of the rope climbing machine mainly depends on electromagnetic braking or mechanical friction braking driven by electricity, and both braking structures are arranged on a shell of a transmission mechanism of the rope climbing machine. The electromagnetic brake mainly utilizes an electric drive brake to realize quick braking, and the phenomenon that the electromagnetic brake cannot work normally occurs when power is off. Mechanical friction braking achieves braking by friction, but has a slow response speed, and the braking effect is reduced due to abrasion after long-time use. Thus, there is a need for a braking structure that responds quickly in the event of a power failure.
