The invention discloses an energy-saving elevator emergency rescue method which comprises the following steps: after an elevator is powered off, a rescue device is started, and the elevator is stopped; then stopping the elevator to enable the car to be in a free lifting state; relative movement is formed between the elevator and the counterweight device due to weight difference, so that the elevator is stressed to ascend or descend, and then the rescue device senses the ascending and descending direction of the elevator; the elevator is stopped, then driving force is applied to the elevator, and the elevator continues to move in the lifting direction in the second step and reaches the leveling position; and finally, power supply to the elevator is cut off, and the elevator is shut down. The heavy load direction of the elevator can be detected before emergency rescue, the elevator is driven to move in the heavy load direction, and the beneficial effects of being good in energy-saving effect and high in safety are achieved.
本发明公开了一种节能式电梯应急救援方法,包括以下步骤:电梯断电后救援装置启动,制停电梯;然后关闭对电梯的制停使轿厢处于自由升降状态;电梯和对重装置之间因重量差形成相对移动,使电梯受力上升或下降,再由救援装置感应电梯的升降方向;制停电梯,再对电梯施加驱动力,使电梯按步骤②中的升降方向的继续移动并抵达平层位置;最后断开对电梯的供电,关停电梯。本发明能够在紧急救援前检测电梯的重载方向,并驱动电梯沿重载方向进行移动,具有节能效果好、安全性高的特点。
