Description

The automatic detrainment device of elevator emergency

Technical field

The utility model relates to the cage lifter apparatus field, the automatic detrainment device of especially a kind of elevator emergency.

Background technology

In the increasing life of coming into people of elevator now, elevator is all adopted in places such as the house of little high level, business offices, but also there is certain potential safety hazard in elevator.When operating elevator, when running into the power failure of electric power system fault or external power grid, will make the car of operation out of service at once, the passenger will be trapped in the car and can't leave, and maintainers' such as needs rescue just can make the passenger leave.And this process need regular hour often causes delaying of certain Psychological Panic and time for stranded passenger, and because elevator tends to rest between the two floors; Under panic situation; The passenger pries open car door, makes passenger's elevator that drops easily, causes the life contingency.

The utility model content

The purpose of the utility model is that a kind of automatic detrainment device of elevator emergency that stranded passenger is evacuated rapidly is provided for the deficiency that solves above-mentioned technology.

In order to achieve the above object; The automatic detrainment device of the utility model institute design-calculated elevator emergency; It mainly comprises storage battery, charging module, single-phase inversion power supply, three phase inverter, master control module, interface module, and the 220V power supply is connected with storage battery through charging module; Storage battery is given IGBT control module, ups power module and interface module power supply respectively; The ups power module is given master control module and interface module power supply; Master control module controls IGBT control module, interface module, ups power module; The IGBT control module is connected the control elevator door-motor system with interface module, control elevator traction machine work simultaneously; Elevator master electro-detection module is connected with three-phase AC380V power supply; Coder on the elevator is connected with Logic control module, the service condition of feedback elevator traction machine; Interface module is connected, connects to layer photoelectric sensor with door machine, traction machine brake, and the safety door latch loop on the elevator, maintenance loop are connected with interface module simultaneously.This structure:, when the detection civil power fails to supply with, give the device actuation signal through elevator master electro-detection module; Receive each signal through interface module simultaneously; Pass to the master control module, the master control module with preset optimal case operation, is evacuated stranded passenger according to the signal control elevator.

The automatic detrainment device of the resulting elevator emergency of the utility model; Setting through charging module and storage battery; Can when civil power fails to supply with, to elevator and this device electric energy be provided, the setting of ups power module can become the voltage transition of storage battery elevator and each required voltage of this device.The master control module can detect the various signals of elevator input, simultaneously through the output of control IGBT control module, controls the operation sheet of this device and elevator.Interface module is then isolated conversion to original signal of elevator and each parts.This device is through the master control module, and the cage operation of the elevator that control fails to supply power is floor extremely recently, and opens car door and entrance hall, can save electric energy, can realize the evacuation to stranded passenger in the energy supply scope of assurance storage battery.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Combine accompanying drawing that the utility model is done further to describe through embodiment below.

Embodiment 1:

The automatic detrainment device of elevator emergency as shown in Figure 1, that present embodiment is described, 220V power supply 2 is connected with storage battery 4 through charging module 3; Storage battery 4 is given IGBT control module 7, ups power module 6 and interface module 8 power supplies respectively; Ups power module 6 is given master control module 5 and interface module 8 power supplies; Master control module 5 is controlled IGBT control module 7, interface module 8, ups power module 6; IGBT control module 7 is connected control elevator door-motor system 11 with interface module 8, control elevator traction machine 10 work simultaneously; Elevator master electro-detection module 9 is connected with three-phase AC380V power supply 1; Coder 16 on the elevator is connected with master control module 5, the service condition of feedback elevator traction machine 10; Interface module 8 is connected, connects to layer photoelectric sensor 13 with door machine 11, traction machine brake 12, and the safety door latch loop 14 on the elevator, maintenance loop 15 are connected with interface module 8 simultaneously.

The practical implementation method: the automatic detrainment device of elevator emergency detects through 9 pairs of civil powers of elevator master electro-detection module; When mains failure; Elevator master electro-detection module 9 is sent signal, after the automatic detrainment device of elevator emergency obtains power cut signal, and startup work behind the time-delay 5s.After the automatic detrainment device startup of the elevator emergency work, horse back is to the safety return circuit of elevator, loop of the door lock; The maintenance loop is detected; All safety switchs are all normal when detecting, and the automatic detrainment device of elevator emergency begins to judge the position of lift car, if elevator is in a zone position; Device is given the power supply of elevator door-motor 11 systems, and hoistway door and gate are opened; If elevator is in the not gate zone position, the automatic detrainment device of elevator emergency will drive elevator traction machine 10, and elevator is run to floor nearby, and open Room door and gate.In the automatic detrainment device operational process of elevator emergency, any safety switch breaks off, and the automatic detrainment device of elevator emergency quits work immediately.
