Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.
[0023] Example. A kind of emergency rescue method of elevator, constitutes as figure 1 shown, including the following steps:
[0024] ①The rescue device starts after the elevator is powered off. After the rescue device is started, it first detects its own voltage through the voltage detection relay. When the detected value is lower than the minimum pull-in voltage of the elevator brake, directly enter step ⑤. When the minimum pull-in voltage is reached, enter the next step;
[0025] ②The rescue device detects the load in the car. When there is no load in the car, go directly to step ⑤. When there is a load in the car, go to the next step;
[0026] ③The rescue device detects the position of the elevator in the well, and when the elevator is in the leveling position, enter the next step; when the e...
