The invention discloses a manual rescue device of a motor driven
elevator. When a working power supply is powered off so that the
elevator cannot normally move, a normally-
open contact is switched off, a normally-closed contact is switched on, a rescue loop is formed by a
standby power supply, the normally-closed contact, a
key switch, a button switch, a left contracting
brake and a right contracting
brake and the
key switch and the button switch are operated to be switched on, so that the left contracting
brake and the right contracting brake are powered on to be opened. When the working power supply is stilled powered on, but the
elevator has other failures so as not to normally move, the normally-
open contact is switched on, the normally-closed contact is switched off, a rescue loop is formed by the working power supply, the normally-
open contact, the
key switch, the button switch, the left contracting brake and the right contracting brake, and the key switch and the button switch are operated to be switched on, so that the left contracting brake and the right contracting brake are powered on to be opened, and thus, due to the opening of the left and right contracting brakes, a lift car can move to a flat
bed position to release passengers. The left and right contracting brakes can be supplied with power by the working power supply or the
standby power supply to be opened only through switching on the key switch and the button switch, so the manual rescue device is simple and convenient to operate, the passengers stuck in the lift car due to the power failure or other failures can be emergently rescued and are timely evacuated and the risk is avoided.
