The invention relates to the technical field of elevator power failure emergency rescue, in particular to an elevator power failure emergency rescue method and system. The method comprises the steps of loosening an elevator gate when commercial power is in a power failure state, enabling the heavier side of a car side and a counterweight side to operate in the gravity direction until a car operates to a door region, and driving a traction machine to enable the car to stop operating. In the prior art, after an elevator is powered off, the traction machine needs to be continuously driven until rescue is completed, and therefore the requirement for the capacitance of an emergency storage battery is high, compared with the prior art, the weight difference between the car side and the counterweight side is fully utilized, so that the requirement for the traction machine is effectively reduced, and the requirement for the capacitance of a storage battery is effectively reduced.

    本发明涉及电梯停电应急救援技术领域,尤其涉及一种电梯停电应急救援方法及系统,包括:当市电处于停电状态时,松开电梯闸机以使轿厢侧与对重侧中较重的一侧延重力方向运行直至轿厢运行至门区时,驱动曳引机以使轿厢停止运行。现有技术中,当电梯停电后,需要持续驱动曳引机直至救援完成,这就导致了对应急蓄电池的电容量要求比较高。相较于现有技术,本发明充分利用了轿厢侧与对重侧之间的重量差,从而有效减少了对曳引机的需求,进而有效降低了对蓄电池的容量需求。
