Abstract

The invention relates to an elevator rescue method. The elevator rescue method comprises the steps of S10, using an automatic rescue system for rescue; S20, judging whether automatic rescue fails or not; S30, if automatic rescue fails, starting a standby rescue system, comparing the weight of a counterweight filler and the weight of a lift car, and opening a a band-type brake of a traction machine; and S40, if the weight of the counterweight filler is not equal to the weight of the lift car, driving the lift car to move through the weight difference between the counterweight filler and the lift car; and if the weight of the counterweight filler is equal to the weight of the lift car, dragging the lift car to move through an auxiliary traction device. Compared with a conventional automatic rescue mode, the elevator rescue method can improve the rescue success rate; and compared with a manual rescue mode, the rescue time can be shortened, so that the panic emotion of passengers is relieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator rescue method. Background technique [0002] With the gradual increase in the height of modern buildings, the application of elevators is becoming more and more extensive. People no longer need to climb stairs to go up and down. Elevators have significantly improved people's quality of life. However, during the daily operation of the elevator, failures or power outages may occur and cannot be used normally. [0003] If the elevator breaks down or has a power outage, it is usually necessary to activate the automatic rescue system for rescue, or manually rescue the trapped passengers in the elevator. However, if there is an abnormality in the control circuit during the automatic rescue process, the rescue cannot be carried out, and manual rescue needs to be waited for. If manual rescue is adopted, rescuers may not be able to rush to the rescue scene immediately, and...
