Specific implementation mode
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 are attached to
Enabling safety control system.Switch module is set in gate position (lift car enabling side), the switch module is by dynamic
Component and static component two parts composition, that is, include the static component inductive switch coupled with elevator main control board 10, and fixed
Dynamic component inductive head on car movement door, that is, gate (similarly hereinafter), inductive head are fixed on the bottom end of car movement door, induction
Switch is arranged in car floor 7.Usually, inductive switch is connect by car top control panel 11 with elevator main control board 10；And it opens
The induction working condition distance closed between component 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..
It separates in being applied to below with electromagnetic induction switch and is illustrated for embodiment in door：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 incudes for bistable magnetic
Switch 8, inductive head are permanent magnetism head 9.Two permanent magnetism heads 9 are 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 corresponding with two permanent magnetism heads 98 is respectively equipped in car floor 7.
Its electrical control is as shown in Figures 3 to 5, including elevator main control board 10 and car top control panel 11, wherein elevator master control
Plate 10 is satisfied in 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 car communication cables 12.
In the CN0 interfaces of elevator main control board 10, including input port X1, X3 are detected in hoistway door, car door lock protection contact,
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 the ports CH1~CH3, 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 enabling
It surveys contact SK1 and detects contact SG1 normally-closed contacts with door-closing in-place, AM is as public electricity output high level signal.When elevator is closed the door
After in place, door lifter output signal cuts off SG1, then A1 no longer receives high level signal, and system can judge that door machine is closed the door accordingly
In place, principle in place of opening the door is identical.I.e. system using the Proof-Of Principle elevator cage door open and close in place whether.
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 head 9 need to reach induction working condition, 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) allows normal use.If conversely, one having 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 car movement door be univalve door plate or more folding side opening door or in point more folding doors etc., inductive head is equal
Positioned at gate towards the bottom part in switch direction, every piece of gate bottom end configuration inductive head can be selected, and static component incudes
Switch setting is in car floor 7 towards the one end in enabling (closing door) direction, and when certain multiple spot installs inductive head, each inductive switch exists
Corresponding position is flexibly arranged in parallel.
Above-described embodiment is the explanation to the utility model, is not the restriction to the utility model, any new to this practicality
Structure etc. after the simple transformation of type belongs to the scope of protection of the utility model.
