Abstract:
An emergency escape device (1) for elevators is revealed. The emergency escape device (1) is disposed in an elevator system. The emergency escape device (1) includes a motor (11) having an output end (111) linked to a reduction gear set (12). An inner gear (122) of the reduction gear set (12) is engaged with a gear (141) of a rope winder (14) around which a steel cable (2) is wound. Thereby the motor (11) is released automatically from braking when the elevator system loses power and stops due to power outage or mechanical failure. Thus an elevator cabin (3) is pulled downward by gravity and the rope winder (14) rotates to unwind the wound steel cable (2). The steel cable (2) goes down slowly so that the elevator cabin (3) can goes down and stop at the nearest floor, allowing people trapped to come out.
