A contact 32 and B contact 33 are contacted and are conducted, and constitute one of switch unit of loop of the door lock, multiple switch unit is gone here and there again
Connection composition door lock safety return circuit, entire circuit conducting, then allow elevator to run.
More preferably, the A contact 32/35 of the main door lock-switch 12/22 of same hall door and secondary door interlock switch 16/26 conductance each other
Lead to and connect, two B contacts conduct with the B contact of another two hall door 38 connect respectively, make appended by two door leafs of a hall door
The door interlock switch of band forms a switch unit, then exports two contact lead-wire ends respectively and connect with another two switching means conductive,
Each switch unit combines series connection and forms door lock safety return circuit（Abbreviation loop of the door lock）；The spare loop of the door lock 21 with
The circuit arrangement mode of the daily loop of the door lock 11 is identical, and can be disposed adjacent, i.e., on original loop of the door lock basis
It is upper to increase a set of essentially identical loop of the door lock.
More preferably, the main door lock-switch 12 of same hall door and spare main door lock-switch 22 are arranged side by side on a headstock 31 and door
It at the opposite face of machine 36, opens the door and disconnects door interlock switch, cut off door lock safety return circuit, elevator locking may not operate；It closes the door and is closed
When, loop of the door lock is connected in door interlock switch closure, and elevator normally goes up and down operation.When daily loop of the door lock failure disconnects, elevator sheet
In the case that body is safety, spare loop of the door lock 21 is connected and substitutes daily loop of the door lock operation elevator, until lift car is mobile
To level position, until rescue trapped person leaves carriage completely.The secondary door interlock switch 16 of same hall door is opened with spare secondary door lock
It closes 26 to be arranged side by side at a headstock 31 and the opposite face of door machine 36, completes safety detection when opening or resetting to another door leaf
And the control for safe operation elevator of closing the door, avoid the operation elevator that opens the door.For convenience of design and installation, facilitate configuration spare and accessory parts,
Gate is consistent with the door interlock switch arrangement of hall door.
More preferably, the switching switch is relay, can be convenient quickly switching circuit.
It above disclosure is merely preferred embodiments of the utility model, certainly cannot be practical new to limit this with this
The interest field of type, therefore equivalent variations made according to the patent scope of the utility model still belong to the utility model and are covered
Range.
