Description
Technical field
The present invention relates to elevator control technology, especially a kind of elevator cage door completely closes verification protective device.
Background technology
With the continuous upgrading of the market demand, elevator safety technical requirements are also constantly striding forward.Existing security control, just
Product in itself for, various technical standards are substantially comprehensive to the greatest extent, it may be said that lift product is a kind of comprehensive product of safeguard protection.
But elevator safety accident still happens occasionally, and designed the reason for indivedual accident generations beyond the existing safeguard protection of elevator,
As whether in the completely closed state etc. for elevator cage door.Public technology is also rare to be related to, and retrieving patent publication No. such as is
CN106966279A, a kind of disclosed elevator door prevents the device that elevator is run when not completely closing, including expands current circuit, electricity
Resistance, switching diode, contact and ammeter；Wherein expand current circuit to be closed by what current regulator diode, transistor and protective resistance formed
Close circuit；This device is protected in itself merely by electric-control system, and the gate of layer door position can only be controlled, and is used
With prevent elevator because of electrical contact short circuit the accident that triggers.
And in elevator actual motion, if under regular situation, the closing situation of gate is electrically secondary by door lifter door-closing in-place
Lock-switch carries out door-closing in-place verification, this safety switch verification door-closing in-place, and apparatus for controlling elevator calculates elevator cage door and closes, electricity
Ladder starts normal operation.But in this situations below, as door machine hanging plate is connected with gate unreliable, gate occurs and comes off, or gate
Deform under external force, causing gate, door hanging plate door-closing in-place, electrical validation gate has been located to close in closing process,
In fact, gate possibly can not state in the closed position, as shown in Figure of description 6.In this case, elevator is not tested
The actual closed position situation of gate is demonstrate,proved, can still carry out normal operation.This state, door of elevator (gate) is in operational process
In, it is possible to have and come off dangerous or shock accident or shearing accident occurs, can also cause passenger alarmed, and then erroneous judgement elevator
Failure, carries out other uncontrollable risky operation, door of such as lying prone.

Embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
A kind of elevator cage door of the present embodiment completely closes verification protective device, including door lifter 1 and door lifter 1 attach
Enabling safety control system.Switch module is set in car door position (lift car enabling side), the switch module is by moving
State component and static component two parts composition, that is, include the static component inductive switch coupled with elevator main control board 10, Yi Jigu
The dynamic component inductive head being scheduled on carriage movement door i.e. gate (similarly hereinafter), inductive head are fixed on the bottom of carriage movement door, sense
Inductive switch is arranged in car floor 7.Usually, inductive switch is connected by car top control panel 11 with elevator main control board 10；And
Sensing working status distance between switch module dynamic component and static component is 5mm~8mm.
Switch module can be selected electromagnetic induction switch, light sensation inductive switch, piezoelectricity inductive switch or capacitive induction touch and open
Close etc..
Separate in being applied to below with electromagnetic induction switch and illustrated in door for embodiment：In separate door include mutually it is right
The left gate plate 3 and right gate plate 4 closed, referring to Fig. 1, Fig. 2, the inductive switch part of electromagnetic induction switch senses for bistable magnetic
Switch 8, inductive head is permanent magnetism first 9.Two permanent magnetism first 9 is taken to be arranged in the bottom part of left gate plate 3 and right gate plate 4,
In contrast, static component bistable magnetic inductive switch 8 corresponding with two permanent magnetism first 9 is respectively equipped with car floor 7.
Its electrical control as shown in Figures 3 to 5, includes elevator main control board 10 and car top control panel 11, wherein elevator master control
Plate 10 is satisfied with computer room switch board, and car top control panel 11 is installed in car top inspection box, car top inspection box and elevator main control board 10
Between connected using 485 special carriage communication cables 12.
In the CN0 interfaces of elevator main control board 10, including the protection of hoistway door, car door lock contact detection input port X1, X3,
When elevator hall, gate are opened or are abnormal, when X1, X3 interface are inputted without level signal, system stops driving output, stop elevator
Operation, and corresponding failure code is reported, instruct staff's malfunction elimination.
Car top control panel 11 includes containing CH1~CH3 ports, and wherein CH1 is as communication interface, with elevator main control board 10
CN1 interfaces carry out communication signal connection；CH2 detects port in place as gate open and close, and A1, A2 connect respectively to be examined in place with opening the door
Contact SK1 and door-closing in-place detection contact SG1 normally-closed contacts are surveyed, AM is as public electricity output high level signal.When elevator is closed the door
After in place, door lifter exports signal cut SG1, then A1 no longer receives high level signal, and system can judge organ's door accordingly
In place, principle in place of opening the door is identical.Whether i.e. system uses the Proof-Of Principle elevator cage door open and close in place.
CH3 as gate completely closed state verify switching signal input point, B1, B2 connect respectively with switch module contact,
That is left-handed opening component contacts S1 and the normally closed points of right switch module contact S2, BM is as public electricity output high level signal.Work as elevator
When door completely closes, bistable magnetic inductive switch 8, permanent magnetism first 9 need to reach sensing working status, i.e. gate left-handed opening component contacts
S1 and right switch module contact S2 is disconnected, then B1, B2 point in CH3 will no longer receive high level signal, is coordinated in CH2 interfaces
A1 interfaces (door-closing in-place detection contact)；Inputted when A1, B1, B2 interface in car top control panel 11 while without high level signal
When, by 485 communication interfaces, by the signal transmission to elevator main control board 10, control system could judge that elevator cage door has been in
Full closing state (referring again to Fig. 1), it is allowed to normal use.If conversely, one there is height in A1, B1, B2 interface in car top control panel 11
When level signal inputs, system judges that elevator cage door closes abnormal, state as shown in Figure 6, then stops driving output, stop electricity
Ladder operation, and corresponding failure code is reported, instruct staff's malfunction elimination.
In addition, for carriage movement door for univalve door plate or more folding side opening door or in point more folding doors etc., inductive head is equal
Bottom part positioned at gate towards switch direction, can select every piece of gate bottom configuration inductive head, and static component senses
Switch is arranged on car floor 7 towards the one end in (conjunction door) direction of opening the door, and when certain multiple spot installs inductive head, each inductive switch is in phase
Position is answered flexibly to be arranged in parallel.
Above-described embodiment is the description of the invention, is not limitation of the invention, any simple transformation to the present invention
Rear structure, method, technique etc. belong to protection scope of the present invention.
