Embodiment Construction

[0010] The structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] see figure 1 As shown, the manual rescue device of the motor-driven elevator includes a contactor 10, a key switch 7, a button switch 8, a motor left brake 1 and a right brake 2 connected in parallel, a working power supply 3, a backup power supply 4, and a contactor 10 It includes a normally open contact 5 controlled by the working power supply 3 and a normally closed contact 6 controlled by the working power supply 3. When the working power supply 3 supplies power, the normally open contact 5 is closed and the normally closed contact 6 is disconnected; When the working power supply 3 is powered off, the normally open contact 5 remains open, and the normally closed contact 6 remains closed. exist figure 1 Among them, the normally open contact 5 is connected in series with the working power supply 3, the normally closed contact 6 is con...

Abstract

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.

Description

[0001] technical field [0002] The invention relates to a manual rescue device for an elevator, in particular to a manual rescue device for a motor-driven elevator. When the elevator fails, rescue is performed by manual operation. Background technique [0003] When the elevator is trapped, the rescue device is manually operated through the backup power supply, so that the elevator runs to the nearby floor to open the car door and rescue the passengers. [0004] In the prior art, the manual rescue device generally opens the mechanical brake of the motor through a manual brake release device, so as to realize the free movement of the car. With the development of the economy, the operating space for the motor is getting smaller and smaller on the motor-driven elevator, resulting in time-consuming and labor-intensive operation of the existing manual rescue device. Contents of the invention [0005] The object of the present invention is to provide an easy-to-operate manual r...
