Description
Technical field
The utility model is related to a kind of elevator devices, independently getting rid of poverty when breaking down more particularly, to a kind of elevator device
Elevator device driving circuit.
Background technology
The modern life, the development in city, high building stand in great numbers, and skyscraper be unable to do without elevator, dependence of the modern to elevator
Higher and higher, the people's lived in high building also can constantly increase, and the safety hidden danger of people is also needed to be considered
Safety problem, first to go on a journey daily for high building inhabitation people and the last one vehicles are to take elevator;
And go on a journey the required vehicles of institute as people in high building -- for elevator, elevator while providing convenient service for people,
Elevator faults and oppressive problem are then that people need the security hidden trouble paid much attention to, gently then delay time at stop or business opportunity, weight
Then cause injured and injures and deaths safety accident.
Since elevator itself is used as a kind of electromechanical integration equipment, in its longtime running lifting process, inevitably there is meeting
It is faulty to happen, and the consequence that elevator faults are brought is typically then:Elevator emergency is parked in the non-leveling zone of elevator shaft,
Up and down must not, need to wait for elevator professional personnel and come to rescue.
But elevator professional personnel cause elevator professional personnel to overtake and come since the situations factor such as traffic and road distance limits
The time length of rescue is different, and long possibility needs one hour or even a few houres, within the so long time, when trapped person is long
Between in closed space, be easy to cause high-pressure and expiratory dyspnea, if people is more, air quality can worse and worse,
The people of constitution difference even there is also fall in a swoon equal anxious discovery as.For the elderly, itself illness with it may
More, if the stranded time is grown, personnel can't come out immediately, around without properly rescuing, it is easy to cause in sedan-chair
Best rescue time can be missed in compartment and causes sorry problem.
Although some present producers propose or use a little not oppressive elevator solutions, cardinal principle is:It will show
The maintenance function of elevator(lift) machine room be transplanted in car as former state;Its prerequisite is exactly that electric life controller and driver are necessary
It is good, could saves oneself in this way.It is exactly opening of the maintenance function of lift car to stranded passenger for a certain degree,
And operation of saving oneself is more professional.
1. being driven in terms of operation logic from it:Or output of the frequency converter of elevator to traction host.
But when elevator faults occur for such case, if controller or driver itself also go wrong, that is just saved oneself
Also it cannot effectively run.
2. being segmented from the total breakdown of elevator, existing not oppressive rescue reply situation is also relatively limited:
1.)Control system is normal, and the circuit of the urgent electric operation of elevator is abnormal or safety return circuit failure, usually electricity
Terraced emergency stop, it is out of service.
2.)Safety return circuit is normal, and electric life controller, encoder, transformer, frequency converter failure.
3.)Failure in terms of non-security circuit, for example contacts of contactor longtime running feedback is abnormal, plug-in unit loosens contact not
Good, power line shorted to earth etc., control circuit poor contact.
4.)Elevator power failure or failure, power source trip.
5.)Elevator door lock loop disconnects.
Case above can cause elevator it is improper stopping and it is oppressive.Existing way only in the first case described above may be used
With rescue.
Utility model content
The utility model is to solve existing elevator oppressive security risk phenomenon occur because of improper stopping failure, and be stranded
Personnel wait for rescue before professional reaches in elevator and cannot preferably carry out safely and effectively saving oneself in time, to
A kind of trapped person for causing initiation subsequently to follow the present situations such as security hidden trouble and providing can cope with more in stranded elevator
A variety of elevator faults lead to oppressive event and are effectively saved oneself, and improve trapped person's life security, reduce injures and deaths hidden danger hair
