Abstract
The utility model relates to the technical field of elevators, in particular to a car accidental movement protective device, which comprises an independent door lock contact, a well induction switch, a unintended car movement protection (UCMP) control circuit board, an elevator system input monitoring device, a band-type brake power supply, an output control device and a band-type brake, wherein the UCMP control circuit board is respectively connected with the independent door lock contact, the well induction switch, the elevator system input monitoring device and the output control device, and the band-type brake power supply is connected with the band-type brake through the output control device. The car accidental movement protective device adds a set of elevator protective device based on an original elevator system, and is used to detect whether an elevator car accidently moves when a door is opened, thereby enabling elevator passengers to be safer.
Description
Technical field
The utility model relates to elevator technology field, relates in particular to a kind of car accidental movement fender guard.
Background technology
Elevator is a kind of vertical conveyor take electrical motor as power, and case shape gondola is housed, and for tier building, takes advantage of people or carrying goods.Elevator is as the transport facility of vertical direction, become important Architectural Equipment and indispensable in skyscraper and public place.Along with the development of computer technology, automatic technology and Power Electronic Technique, modem elevator has become typical electromechanical integrated product.Along with the raising of overall national economy strength, the people's personal consumption level rises appreciably, real estate developer releases medium-to-high grade little high level and high-rise residential building one after another energetically, has driven increasing rapidly of residential lift, becomes the main growth point in whole elevator market.
Existing apparatus for controlling elevator is by detector switch gate signal when opening the door flat bed, and band-type brake contactless switch signal feedback guarantees that passenger passes in and out the personal safety of car.But may there is following hidden danger in this process:
(1) when elevator switch gate signal lost efficacy, or due to improper operation, switch gate signal is during by short circuit, and elevator likely moves in the situation that opening door, the passenger's that harm is passing in and out personal safety.
(2) due to elevator device malfunction and failure, make car abnormal running, for example open mistakenly traction machine brake.
Summary of the invention
The purpose of this utility model is to provide a kind of car accidental movement fender guard for the deficiencies in the prior art; on the basis of original elevator device, newly increase a set of elevator protection device; the accidental movement of whether opening door for detection of lift car, makes elevator passenger safer.
For achieving the above object, the utility model adopts following technical scheme: a kind of car accidental movement fender guard, and it comprises independent door lock contact, hoistway inductive switch, UCMP control circuit board, elevator device input monitoring device, band-type brake power supply, output-controlling device and band-type brake; Described UCMP control circuit board is connected with independent door lock contact, hoistway inductive switch, elevator device input monitoring device and output-controlling device respectively, and described band-type brake power supply connects described band-type brake by output-controlling device.
Described band-type brake is synchro traction machine band-type brake.
A kind of car accidental movement fender guard described in the utility model newly increases a set of elevator protection device on the basis of original elevator device, whether is opening the accidental movement of door for detection of lift car, makes elevator passenger safer.
Accompanying drawing explanation
Fig. 1 is electrical principle schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Fig. 1, a kind of car accidental movement fender guard described in the utility model, it comprises independent door lock contact 1, hoistway inductive switch 2, UCMP control circuit board 3, elevator device input monitoring device 4, band-type brake power supply 5, output-controlling device 6 and band-type brake 7; Described UCMP control circuit board 3 is connected with independent door lock contact 1, hoistway inductive switch 2, elevator device input monitoring device 4 and output-controlling device 6 respectively, and described band-type brake power supply 5 connects described band-type brake 7 by output-controlling device 6.Further, described band-type brake 7 is synchro traction machine band-type brake.
Above-mentioned a kind of car accidental movement fender guard, described hoistway inductive switch 2 is for detection of car position; Described independent door lock contact 1 is for detection of elevator door switch state; Described band-type brake power supply 5 is for providing band-type brake 7 to open required electric energy; Described UCMP control circuit board 3 is for detection of above-mentioned device signal, and judge according to car position, elevator door switch state whether elevator car accidental movement occurs, if there is car accidental movement, UCMP control circuit board 3 is exported control signal, makes output-controlling device 6 cut off the current supply circuit between band-type brake power supply 5 and band-type brake 7; Elevator device input monitoring is installed on the mode of operation that detects UCMP control circuit board 3, if UCMP control circuit board 3 mode of operations are abnormal, elevator device input monitoring device 4 makes elevator stop normal service.
In sum, a kind of car accidental movement fender guard and guard method newly increase a set of elevator protection device on the basis of original elevator device, whether are opening the accidental movement of door for detection of lift car, make elevator passenger safer.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
