The invention provides a screw elevator self-rescue mechanism. The screw elevator self-rescue mechanism comprises a screw lifting mechanism with a screw and a lift car. A locking assembly is arrangedon the lift car so that a driving nut on the screw can be detachably connected with the lift car. Then, a self-driving assembly with a movable nut is arranged between the screw and the lift car, a self-driving operation part of the self-driving assembly is arranged in the lift car, and the internal self-driving function is achieved. When an elevator normally runs, the screw rotates to drive the lift car to move in the depth direction, and a safety nut is fixed relative to the lift car. When the elevator breaks down and the screw cannot rotate, a passenger triggers the locking assembly in the lift car, the driving nut is unlocked to be disengaged from the lift car, then the safety nut is driven to rotate relative to the screw, the lift car of the elevator moves in the depth direction in a self-driving manner, and self-rescue is achieved.

    本发明提供了一种螺杆电梯自救机构,包括具有螺杆的螺杆升降机构以及轿厢,通过在轿厢上设置锁合组件,以实现螺杆上的驱动螺母与该轿厢之间可拆连接;而后,通过在螺杆与轿厢之间设置螺母可动的自驱组件,自驱组件的自驱操作部设于轿厢内部,实现内部自驱动功能:在电梯正常运行时,螺杆转动,驱动轿厢纵深移动,安全螺母相对轿厢固定;当电梯故障,螺杆无法转动时,乘员由轿厢内触发锁合组件,实现驱动螺母解锁脱离轿厢,而后再驱动安全螺母相对螺杆转动,实现电梯轿厢纵深自驱移动,实现自救。
