The elevator control cabinet alarms. ; The the whole elevator safety circuit disconnects. ; The the cage stops. ; and The the elevator is in the inspection state. ; so Harm harm to other people can be avoided.

Description

The unusual open detection device of elevator door
Technical field
The utility model relates to a kind of safety device of elevator, and especially a kind of elevator that is used for detects the unusual open detection device of elevator door whether elevator door is opened unusually.
Background technology
According to standard GB 7588-2003 " elevator manufacturing and safety standard " regulation, elevator can not be opened layer door when normal operation, unless car in the onlocking zone of this layer door, stop or stopping, to realize to the dangerous protection of falling; When layer door opened, under normal operation, can not start elevator or keep elevator to continue operation, to realize protection to shearing.
Existing layer door safety guard mainly is mechanical,,, by door-opening mechanism layer door is opened when cage operation is in onlocking zone on the layer door lock by the mechanics on the layer door.This kind device, in case layer door drawn back by force, physical construction will no longer work, elevator can not be taked other safety method, is easy to the accident of meeting accident.
Summary of the invention
The technical problems to be solved in the utility model provides the unusual detecting device of opening of a kind of elevator door simple in structure, dependable performance.
The purpose of this utility model is achieved in that the unusual open detection device of a kind of elevator door, comprise treatment circuit, be arranged on the guide rail with the corresponding hoistway switch of each floor, the layer door switch on the layer door suspension member of each floor is set, described all hoistway switches and layer door switch all are connected with described treatment circuit, described hoistway switch is in normally open, and described layer door switch is in normally off; Described hoistway switch is connected successively, the setting that is in parallel of the described hoistway switch of layer door switch and this floor of described each floor.
Described hoistway switch comprise be arranged on the guide rail with the corresponding permanent magnet induction relay of each floor, be arranged on the magnetic isolation plate on the car suspension member, when the flat bed place of a certain floor of elevator car arrives, described magnetic isolation plate makes described hoistway switch closure.Described layer door switch comprises the proximity Hall switch that is arranged on the side layer door suspension member, is arranged on the magnet steel on the opposite side layer door suspension member, and when the layer door of elevator opened, described layer door switch opened.Described treatment circuit is that low level rank exceeding signal produces circuit.
Because the utilization of technique scheme, the utlity model has following advantage: it is simple and reliable that this layer door opened the physical construction and the electric mechanism of warning device unusually, can judge the unusual unlatching of layer door accurately, and the generation alerting signal conveys to control housing, elevator control cabinet is reported to the police, and whole elevator safety loop disconnects, the car brake, elevator is in inspecting state, in case other staff are damaged.

Wherein, 1, the car suspension member, 2, guide rail, 3, the hoistway switch, 4, the permanent magnet induction relay, 5, magnetic isolation plate, 6, layer door suspension member, 7, layer door switch, 8, proximity Hall switch, 9, magnet steel, 10, treatment circuit.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail: the unusual open detection device of a kind of elevator door, comprise treatment circuit 10, be arranged on the guide rail 2 with the corresponding hoistway switch 3 of each floor, be arranged on the layer door switch 7 on the layer door suspension member 6 of each floor, described all hoistway switches 3 and a layer door switch 7 all are connected with described treatment circuit 10.Described hoistway switch 3 is in normally open, when car arrives the flat bed place of a certain floor, and described hoistway switch 3 closures; Described layer door switch 7 is in normally off, and when layer door opened, described layer door switch 7 opened.
In the present embodiment, described hoistway switch 3 comprise be arranged on the guide rail 2 with the corresponding permanent magnet induction relay 4 of each floor, be arranged on the magnetic isolation plate 5 on the car suspension member 1, when lift car arrived the flat bed place of a certain floor accurately, described magnetic isolation plate 5 made described hoistway switch 3 closures; When lift car left this flat bed place, described magnetic isolation plate 5 was along with car leaves, and then described hoistway switch 3 disconnects.
Described layer door switch 7 is near switch, can adopt magnet contactor, inductance switch, capacitance switch etc. near switch.In the present embodiment, described layer door switch 7 comprises the proximity Hall switch 8 that is arranged on the side layer door suspension member 6, is arranged on the magnet steel 9 on the opposite side layer door suspension member 6, and when the layer door of elevator closed, described layer door switch 7 was in closure state; When the layer door of elevator whatsoever reason open (comprise normally stop to open the door or open) because damage, described layer door switch 7 is opened.
Setting that described all hoistway switches 3 are connected successively, the described hoistway switch 3 of the layer door switch 7 of described each floor and this floor is in parallel.Described treatment circuit 10 is that low level rank exceeding signal produces circuit, it comprises the normally closed relay KFB1 that is in series of circuit with described hoistway switch 3, layer door switch 7, described rank exceeding signal produces circuit and also comprises normally closed relay KFB2, normally opened relay KZB1, the normally opened relay KZB2 that is in parallel with layer door switch 7, hoistway switch 3, KFB1 circuit, described KFB2, KZB1, KZB2 all are associated, move with described KFB1, and KFB2 and KZB1 are in series with KZB2 after being in parallel again.
Elevator normal course of operation example: when car accurately runs to a certain floor, described magnetic isolation plate 5 between two magnetic poles of described permanent-magnet relay 4, then described hoistway switch 3 closures.Open the layer door of this floor this moment, then pairing layer door switch 7 opened.When personnel turnover finish or goods place finish after, layer door closed, then described layer door switch 7 closures.Car leaves this floor then, and then described hoistway switch 3 is opened.Entire circuit keeps high level.
The unusual example of opening of layer door: the unusual unlatching phenomenon of layer door, for example: car is in operational process, and layer door is opened; Car comes to a complete stop at a certain floor, and the layer door of non-this layer is opened etc.When unusual unlatching situation appearred in arbitrary layer of door, the layer door switch 7 at all hoistway switches 3 and this layer door place disconnected, and makes KFB1 place cut off the power supply, and entire process circuit 10 is put low level.Normally closed KFB1 relay is opened through after the of short duration time-delay, and together with KFB2 open, KZB1 closure, KZB2 closure, then entire process circuit 10 is put height again.After this low level rank exceeding signal was received by the control housing of elevator, elevator control cabinet was reported to the police, and whole elevator safety loop disconnects, the car brake, and elevator is in inspecting state, in case other staff are damaged.
