Abstract
The utility model discloses an elevator emergency apparatus, which is characterized in that the apparatus comprises a charger of which an input terminal connects with commercial power, a converter of which the input terminal connects with the output terminal of the charger by a primary switch, band brake coils connecting with the output terminal of the converter by a secondary switch and a control loop comprising an impulse controller, a storage battery, a primary relay, a secondary relay and a controlling switch. The primary relay controls the on-off of the fist switch, and the secondary relay controls the cutting on-off of the secondary switch. The changer is connected with the output terminal of the charger. The emergency apparatus of the utility model is controlled by a controller for supplying the current to the band brake in the way of pulse mode, so the band brake can work as the ABS braking system of automobiles to make the elevator slide bit by bit towards the heavy side. Once the elevator gets into the gate region, the controller can alter the output pulse parameters to assure the elevator accessing the level in slower speed and light up the display lamp of the gate region.
Description
Technical field
The utility model belongs to the elevator technology field, especially relates to a kind of elevator emergency device.
Background technology
Existing elevator emergency device is the mode that adopts automatic leveling mostly, as Chinese patent ZL98235072.4, and the complex structure of this elevator emergency device, cost is higher, is not easy to promote.And the manual simplified emergency facility of part is arranged is to utilize common uninterrupted power supply (ups) Unity, directly power by a hand push button switch to band-type brake, the slide car that declutches, but the artificial randomness of the time of opening a sluice gate of this structure is very big, very easily cause slip at a high speed car, rush to summit or squat over a pit to relieve oneself danger.Stranded passenger feels bad in the car, and very shar pounding, vibration sense are arranged, and produces frightened.
Summary of the invention
The purpose of this utility model provides a device that is similar to the automobile ABS drag, declutches by the control by pulses crawl, make elevator a little slide into a district, prevent the driving that exceeds the speed limit, ensure elevator passenger safety.Be particularly suitable for gearless synchronous dynamo or machine-roomless lift, the occasion that can't manually declutch, even or have manually and declutch, but can't guarantee safety, runaway condition not.Can be used as a kind of elevator emergency rescue device of safe, reliable, economic, practical, easy popularization.
Should be achieved in that a kind of elevator emergency device with later-model purpose, it is characterized in that described device comprises:
Charger, the input end and the civil power of described charger join;
Changer, the mouth of described charger links to each other with the input end of changer by first switch;
The band-type brake coil, the mouth of described changer links to each other with the band-type brake coil by second switch;
Control loop, form by pulse controller, storage battery, first relay, second relay and a master cock, described first relay is controlled the shutoff of described first switch, described second relay is controlled the shutoff of described second switch, and wherein said storage battery is connected the mouth of described charger.
Emergency facility of the present utility model is powered to band-type brake with pulse mode by controller control, thereby band-type brake is worked as the abs braking system of automobile, make elevator little by little to heavy side slide car, in case behind the access door district, controller changes the output pulse parameter, make elevator with slower speed near flat bed, light district's indicator lamp simultaneously, allow the emergency personnel know that elevator has arrived a district, can stop emergency operating in place, open the door and emit the passenger.
The utility model has the advantages that simple in structure, economical, with apparatus for controlling elevator and the equal onrelevant of dragging system, easy to install, especially adopt class ABS crawl brake sticking brake system, avoided elevator the danger of car may occur slipping at a high speed, make whole emergency management and rescue process steadily, safety, reliable.
Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
Fig. 1 is an electrical schematic diagram of the present utility model.
The specific embodiment
In Fig. 1, elevator emergency device is made of AC/DC charger 1, storage battery 2, DC/DC changer 3, pulse controller 4 and band-type brake coil 5.The mouth of charger 1 links to each other with the input end of changer 3 by relay switch K11, the K12 of two parallel connections, and the mouth of changer 3 links to each other with band-type brake coil 5 by relay switch K31, the K32 of two parallel connections.Wherein relay switch K11, K12, K31, K32 are respectively by relay K 10, K30 control.
On the basis of said apparatus, also the mouth at charger 1 is provided with a pulse controller 4, this pulse controller 4 is formed a control loop with relay K 10, relay K 30, inching button AN and LED alarm display 7, and joins by the mouth of storage battery 2 with charger 1.By door zone sensors 6 signal of elevator position is passed to pulse controller 4 in addition.
Simply introduce the service condition of said apparatus below.When civil power just often, the conventional lifting of elevator, K switch 1 closure, and the biswitch of relay K 10, K30 all disconnects, band-type brake coil 5 is failure to actuate, only storage battery 2 charges.
When elevator runs into emergency situation, normally have a power failure or during et out of order, the rescue group presses inching button AN, the loop works that pulse controller 4 and storage battery 2 are formed, changer 3 is upgraded to the required high potential of band-type brake with the voltage of storage battery 2, controller 4 is with predetermined cycle and pulse-width controlled relay K 10, K30, i.e. control relay K switch 11, K12, the adhesive of K31, K32 and disconnection.When elevator load is unbalanced, can slip car to a little low speed of heavier one side.Behind lift car access door district, door zone sensors 6 Jiang Men district signal DZ pass to controller 4, controller 4 changes the voltage cycle that offers band-type brake coil 5, the chopped pulse width, thus shorten each time of opening band-type brake, make elevator with lower speed near flat bed, light district's LED light 7 simultaneously, allow the emergency personnel know that elevator has entered the district of opening the door, can stop ladder and open the door, thereby finish emergency flat layer salvage work.
In the foregoing description, pulse controller 4 can adopt various PLC (programmable logic controller (PLC)), and the model that is preferably MITSUBISHI company of Mitsubishi is FXOS, or Omron OMROM company model is the circuit of SA12 etc.Battery tension is 24VDC, and band-type brake voltage is 110VDC.Certainly, battery also can be 12VDC, and band-type brake voltage should require to decide according to the supporting elevator of reality.
