Description

Autonomous elevator device driving circuit of getting rid of poverty

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 Raw autonomous elevator device driving circuit of getting rid of poverty.

Used specific technical solution is the utility model to solve above-mentioned technical problem：A kind of elevator system that independently gets rid of poverty System driving circuit, including operation box in cage of elevator and permasyn morot three-phase windings, it is characterised in that：In lift car The operation box panel of operation panel is equipped with get rid of poverty rescue button, change-over switch of getting rid of poverty, get rid of poverty change-over switch and change-over contact of getting rid of poverty Device is electrically connected, and rescue button of getting rid of poverty is electrically connected with rescue contactor of getting rid of poverty, and rescue contactor of getting rid of poverty slips downwards with lift car The overrunning governor of vehicle is electrically connected, and it is short that permasyn morot three-phase windings supply line is equipped with two-way motor stator coil Star circuit is sealed on road, and two-way motor stator coil short circuit seal star circuit includes being connected in parallel on permasyn morot three-phase windings and elevator The first envelope star contactor normally-closed contact and the second envelope star contactor between the UVW three-phase pins of integrated drive control chip is normal Open contact；Change-over switch of getting rid of poverty is electrically connected by change-over contact start unit of getting rid of poverty with emergency power supply EPB, rescue button of getting rid of poverty By getting rid of poverty, rescue contact start unit is electrically connected with emergency power supply EPB.When elevator faults occur, trapped person only need to be Simple and practicable rescue operation of saving oneself is carried out in car in lift car on operation panel, simple and safe can be rescued in profession Personnel carry out sufficient safety self-saving before reaching and help operation, only need to be in the car opened in lift car on operation panel It gets rid of poverty and rescues button and change-over switch of getting rid of poverty, and to carrying out carrying out rotation to change-over switch of getting rid of poverty and pressing rescue button of getting rid of poverty, When the work of flat bed indicator light can be waited for light, elevator door door open button is opened, walks out stranded elevator, trapped person rescues behaviour certainly Make it is simple and practicable, safely and effectively；Not oppressive elevator device by the stator coil winding short circuit of permasyn morot three-phase windings, Dynamic brake effect is formed, the car slipping speed of lift car can be short because of the stator coil winding of permasyn morot three-phase windings It connects and forms dynamic brake performance characteristic and become very slow car slipping and decline, maintain essentially in the speed of 0.2-0.4 meter per seconds, have Effect improves trapped person's slow speed of safety and stability that lift car car slipping declines when rescuing certainly, and improving can from rescue safety By property, prevent secondary unexpected injury from occurring.Trapped person's life security is improved, effectively reduces trapped person's injury phenomenon To minimum.It improves the stator coil winding short circuit security reliability of permasyn morot three-phase windings, improves from rescue peace Full validity.

Preferably, the first envelope star contactor normally-closed contact is using two-way normally-closed contact and direct with phase line all the way The electric connection structure of short circuit.It improves the stator coil winding short circuit security reliability of permasyn morot three-phase windings, carries High rescue safety and effectiveness certainly.
