Description
Technical field
The utility model relates to elevator power failure emergence technology field, relates in particular to a kind of elevator power failure emergency rescue device of pacifying function with voice.
Background technology
At present, elevator is manned special equipment, and in actual life, the emergency situation that causes elevator to occur due to power failure factor happens occasionally.All there is certain potential safety hazard in traditional " saving oneself " mode and " he rescues " mode.
The rescue process of traditional " saving oneself " pattern is: after elevator has a power failure suddenly, backup power is only given controller and band-type brake power supply, whether this Time Controller will detect car at level position, if car is at level position, it is motionless that elevator will keep, and now passenger need to manually push elevator door aside and just can walk out car, if car is not at level position, controller is opened band-type brake, the major loop to motor by envelope star loop switch simultaneously, because band-type brake is opened, elevator is by one side operation towards heavier, now motor will be in self power generation state, due to the existence in envelope star loop, the major loop of motor by short circuit together, thereby the electric energy of this self power generation is added on motor winding, according to inductance principle, this electric energy direction is for stoping motor to move corresponding direction, so, motor can fast turn-around, elevator will slowly move, when running to level position, controller detects flat bed signal immediately, close immediately band-type brake, now elevator will be parked in level position, passenger manually pushs elevator door aside again to walk out car, this rescue pattern can only be applied on synchronous dynamo.
The rescue process of traditional " he rescues " pattern is: after elevator has a power failure suddenly, be equipped with emergency source of electrical power because elevator is inner, but this emergency source of electrical power is just powered to interphone, now, by talkback unit and watch house call, watch house is confirmed after stranded situation, reinforming professional rescue group rescues to scene, band-type brake is manually unclamped in the most employing of field rescue, hand-operated manpower jiggering, car is moved to level position rescues, for machine-roomless lift, owing to cannot carrying out hand turning, so, in order to allow the car can quick travel, conventionally the electrical motor adopting in machine-roomless lift is synchronizator.
For " saving oneself " pattern, shortcoming is mainly reflected in:
1) restriction to some extent in the configuration of elevator motor, can only adopt synchronous motor, can not adopt for asynchronous motor;
2) when after Elevator landing, cannot automatically open elevator door, need artificially manually to push elevator door aside, there is so serious potential safety hazard, and can not adopt this rescue pattern for the elevator door with latch hook;
3) after elevator power failure without any power failure instruction, greatly increased passenger's fear sense;
4) cannot judge phase shortage or misphase, in the time of phase shortage or misphase, elevator will not respond.
For " he rescues " pattern, shortcoming is mainly reflected in:
1) need people to rescue for being on the scene, greatly reduce rescue efficiency;
2), for the elevator of asynchronous dynamo, can only adopt traditional manpower jiggering rescue;
3), for machine-roomless lift, can only adopt synchronous motor, and the cost of synchronous dynamo is much higher than asynchronous dynamo;
4), when car deliverance is after level position, need manual unlocking gate to discharge passenger;
5) after elevator power failure without any power failure instruction, greatly increased passenger's fear sense.
Utility model content
The utility model is in order to solve in existing elevator power failure rescue, exist when rescue car to can not automatic door opening after flat bed, after power failure, can not provide voice and pacify prompting, power failure, phase shortage, misphase can not carry out emergency operating, the deficiency of power supply can not automatically switch after power failure, a kind of elevator power failure emergency rescue device of pacifying function with voice is provided, this device car in the time of rescue automatically keeps opening the door after flat bed, after power failure, automatically provide voice and pacify prompting, power failure, phase shortage, misphase all will carry out emergency operating, automatic switchover power supply after having a power failure.
