Emergency escape device for elevator

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.
一种电梯辅助逃生装置,于电梯车厢设有多个钢索轮,钢索轮上绕设有钢缆,钢缆的一端向上绕设固接在紧急逃生装置上,其另端向上绕设过马达主机再向下固接于配重块;紧急逃生装置设有动力源,动力源的出力端连动有减速齿轮组,减速齿轮组的外齿轮设有缓速油压缸,缓速油压缸与缓速齿轮呈偏心状枢接,缓速齿轮与减速齿轮组的外齿轮相啮合,减速齿轮组的内齿轮与卷绳盘的齿轮相啮合,钢缆卷绕固定在卷绳盘上;由此,于电梯因停电、故障等因素使其丧失动力无法运动时,动力源运作,使卷绳盘缓慢转动,将卷绳盘上的钢缆缓慢向下垂放,使电梯车厢下降停靠于最接近的楼层电梯门位置上,让搭乘电梯的人们可以顺利脱逃,在其整体施行使用上更增实用便利性。
