As shown in Figure 1, a kind of elevator power failure flat bed deliverance apparatus: comprise elevator battery isolator control 1, lift car door opener 5, traction machine brake device 4, described elevator power failure flat bed deliverance apparatus also comprises: power failure flat bed control unit 3, electrical energy storage device 6, flat bed signal element 2 and grid cut-off signal element 7, described power failure flat bed control unit 3 and elevator battery isolator control 1, traction machine brake device 4, electrical energy storage device 6, lift car door opener 5, flat bed signal element 2, grid cut-off signal element 7 is connected, described electrical energy storage device 6 also with flat bed signal element 2, traction machine brake device 4, lift car door opener 5, grid cut-off signal element 7 is connected, and the flat bed signal that described power failure flat bed control unit 3 transmits for the grid cut-off signal peace layer signal unit 2 transmitted according to grid cut-off signal element 7 controls traction machine brake device 4, lift car door opener 5, the operation of electrical energy storage device 6, described electrical energy storage device 6 for the grid cut-off signal that transmits according to grid cut-off signal element 7 to flat bed signal element 2, power failure flat bed control unit 3, traction machine brake device 4, lift car door opener 5 is powered or is stopped power supply.
Be provided with the time of declutching in power failure flat bed control unit 3, described power failure flat bed control unit 3 is according to the braking mode of described grid cut-off signal, flat bed signal and the time controling traction machine brake device 4 that declutches.
The operation of the flat bed signal control lift car door opener 5 that power failure flat bed control unit 3 is sent according to flat bed signal element 2.
A kind of elevator power failure flat bed rescue mode: the method comprises the following steps:
A, grid cut-off signal element 7 monitor the external power grid whether supply regular power of elevator;
B, grid cut-off signal element 7 monitor the external power grid power-off of elevator, and grid cut-off signal element sends grid cut-off signal to power failure flat bed control unit 3 and electrical energy storage device 6;
C, Elevator landing.
Described step C is further comprising the steps of:
C1, traction machine brake device 4 brake towing machine;
C2, electrical energy storage device 6 are powered to flat bed signal element 2, power failure flat bed control unit 3, traction machine brake device 4, lift car door opener 5;
C3, power failure flat bed control unit 3 disconnect elevator battery isolator control;
C4, power failure flat bed control unit 3 judge elevator whether flat bed;
When C5, elevator are in level position, power failure flat bed control unit 3 orders about lift car door opener 5 and opens car door; When elevator is not in level position, power failure flat bed control unit 3 controls traction machine brake device 4 and stops braking, lift car slides 10 ~ 80mm, then power failure flat bed control unit 3 controls traction machine brake device 4 recovery braking, if had a power failure in lift car taxiing procedures, flat bed control unit receives flat bed signal, power failure flat bed control unit controls traction machine brake device immediately and recovers braking, repeats step C4.
