Abstract
The invention discloses a device for detecting the non-controllability movement of an elevator cage. When the elevator cage stops at a door area, and a door lock is broken, if a motor rotates, and the elevator cage is in the non-controllability movement, the elevator cage can be locked by a detection control module, an execution module and a stopping module, particularly speaking, after the detection control module detects elevator cage stopping signals, door area signals of the elevator cage positioned at the door area, door lock breaking signals and voltage change signals in the rotation of the motor simultaneously, execution signals are output to the execution module, the execution module moves, the stopping module is started to lock the elevator cage, so that the elevator cage is positioned in a safety state, and the accidents are avoided. If the elevator cage is not at the door are or the door lock is closed, the detection control module can not contact the execution module, so that the elevator cage can not be locked by the stopping module.
Description
Technical field
the present invention relates to detect the non-road-holding property mobile device of lift car.
Background technology
lift car is at Men Qu, and when being in door opening state (this moment, door lock broke off), moving, then can cause danger if the motor rotation makes car that non-road-holding property take place.
Summary of the invention
the purpose of this invention is to provide and detect the device that the non-road-holding property of lift car moves, in case car non-road-holding property takes place moves like this, then this device can lock car, avoids having an accident.
are for achieving the above object; The technical scheme that the present invention adopts is: detect the non-road-holding property mobile device of lift car, thereby the detection control module of signal is carried out in output behind the voltage change signal when comprising the door district signal that can detect car danger signal, this car at the same time and be in a district, door lock cut-off signal and motor rotation, communicate with said detection control module and can be after receiving the execution signal of this detections control module the output action signal execution module, communicate with said execution module and can only be stopped module by what the startup of the actuating signal of this execution module locked said car.
owing to the utilization of technique scheme, the present invention compared with prior art has advantage: be parked in a district at car, when door lock breaks off; If the motor rotation makes car that non-road-holding property take place and moves, then through detecting control module, execution module, only stopping module, can lock car; Specifically, behind the voltage change signal when detecting control module and detecting door district signal that car danger signal, this car be in a district, door lock cut-off signal and motor rotation at the same time, output is carried out signal and is given execution module; The execution module action starts and only stops module, locks car; Make car be in a safe condition, avoid having an accident.If car not in the door district or door lock when closed, then detect control module and can not trigger execution module, thereby car can only not stopped the module locking.
Description of drawings
accompanying drawing 1 is a scheme drawing of the present invention.
The specific embodiment
Structure of the present invention is further set forth below in conjunction with accompanying drawing in
.
are referring to shown in Figure 1; Detect the non-road-holding property mobile device of lift car; Comprise detect control module 1, with detect execution module 2 and 3 that control module 1 communicates, only stop module with execution module 2 and 3 communicates, in Fig. 1, (run signal, danger signal correspond respectively to the high-low level of electric signal with detecting incoming line 5 transmission cage operation signals that control module 1 is electrically connected or danger signal; The indication cage operation still stops); Incoming line 6 transmission gate district signals, the high-low level of door district signal correspond respectively to car and are in a district, break away from door district, incoming line 7 transmission gate lock signals; Break off or closure the voltage change signal during incoming line 4 transmission motors rotations through high-low level indication door lock.Be parked in a district at car, when door lock breaks off, move if the motor rotation makes car that non-road-holding property take place; Then, can lock car, specifically through detecting control module 1, execution module 2 and 3, only stopping module; Behind the voltage change signal when detecting control module 1 and detecting door district signal that car danger signal, this car be in a district, door lock cut-off signal and motor rotation at the same time, output is carried out signal and is given execution module 2 and 3, and execution module 2 and 3 moves; Start and only stop module; Lock car, make car be in a safe condition, avoid having an accident.If car not in the door district or door lock when closed, then detects control module 1 and can not trigger execution module 2 and 3,, car locks thereby can only not stopped module.
This detects the non-road-holding property mobile device of lift car
; The induced voltage that produces when rotated through the detection motor detects car moving under non-operation state under door district and the door opening state; In case detect moving of the non-manipulation of car; Then detect control module and can let execution module move, lock car, prevent that it from moving again through only stopping module.
Claims (1)
1. detect the non-road-holding property mobile device of lift car, it is characterized in that: thus the detection control module of signal is carried out in output behind the voltage change signal when comprising the door district signal that can detect car danger signal, this car at the same time and be in a district, door lock cut-off signal and motor rotation, communicate with said detection control module and can be after receiving the execution signal of this detections control module the output action signal execution module, communicate with said execution module and can only be stopped module by what the startup of the actuating signal of this execution module locked said car.
