Relief relay unit KJX; Comprise relief relay KF and relief relay K switch; The end of said relief relay KF is connected with the other end SMB of short unit SM; The other end of said relief relay KF is connected with the PN of power supply end, and said relief relay KF is used to control the closed of relief relay K switch or break off, and the other end SMB of said short unit SM is connected with the end of relief relay K switch and second switch JX2 through the first switch JX1; The other end of said relief relay K switch and second switch JX2 is connected with the end of gate interlock relay K M, the operation of controlling elevator through the break-make of said gate interlock relay K M with stop.
Break off when elevator door interlock circuit LC failover, cause gate interlock relay K M dead electricity, thereby when making elevator out of service; The repair and maintenance personnel can have the gate interlock of special sign to protect short unit terminals SMA and SMB through on-the-spot short circuit according to operation instructions, realize " maintenance " operation; Remove shorting stub behind the trouble-shooting, recover elevator " automatically " and move, if but because of maloperation or forget the shorting stub of dismantling; Make said gate interlock loop LC still keep the short circuit state, after elevator recovered " automatically " state, first switch JX1 of machine room inspection switch element and second switch JX2 were all closed; Because said relief relay KF is controlling the closed of said relief relay K switch or is breaking off, therefore, at short circuit gate interlock loop LC; When being about to short unit SM terminals SMA and being connected with lead with SMB, relief relay KF be in electric conducting state, control said relief relay K switch disconnection; Make said gate interlock relay K M and loop break off, cause the gate interlock relay K M dead electricity that remains unchanged, thereby make elevator out of service; Forcibly remind professional repair and maintenance personnel to remove shorting stub, guarantee elevator safe operation under " automatically " state, this loop structure is simple; Be easy to set up, cost is low, has but guaranteed equipment and personnel's safety to a great extent.
Concrete, said gate interlock loop LC comprises the gate lock LA and the Room door lock LB of serial connection, they are responsible for controlling the switch of gate and Room door.
Concrete, said elevator door interlocking short circuit protection loop also comprises safety return circuit SC, the end of said gate interlock loop LC is connected with the PL end of power supply through safety return circuit SC.
Concrete, said safety return circuit SC comprises the safety switch of some serial connections, each safety switch all plays certain control action, for example, limit switch, hypervelocity stopcock etc. is arranged.
Specify the function implementation procedure in elevator door interlocking short circuit protection of the present invention loop below in conjunction with Fig. 2 to Fig. 6.
Please refer to Fig. 2, its machine room inspection switch that provides for the embodiment of the invention is allocated to " automatically " position, and the protection of the gate interlock short circuit the during et out of order of gate interlock loop loop state figure.When " automatically " state moved, gate interlock loop LC failover was broken off at elevator, and the terminals SMA of short unit SM and SMB be short circuit not, and whole loop is broken off, gate interlock relay K M dead electricity, and elevator is out of service.
Please refer to Fig. 3, the gate interlock short circuit protection loop state figure of its machine room inspection switch that provides for the embodiment of the invention when " automatically " is allocated to " maintenance " position.At elevator when " automatically " state changes " maintenance " state; First switch JX1 of machine room inspection switch element and second switch JX2 are all closed; Gate interlock loop LC still breaks off, and the terminals SMA of short unit SM and SMB be short circuit not, and whole loop is broken off; Gate interlock relay K M dead electricity, elevator is out of service.
Please refer to Fig. 4, it is allocated to " maintenance " position for the machine room inspection switch that the embodiment of the invention provides from " automatically ", and the protection of the gate interlock short circuit during with gate interlock loop short circuit loop state figure.After elevator changes " maintenance " state from " automatically " state; The first switch JX1 and second switch JX2 are all closed, and gate interlock loop LC still breaks off, the terminals SMA of short unit SM and SMB short circuit; The loop is connected; Gate interlock relay K M gets electric, and elevator can " overhaul " operation, keeps in repair.
Please refer to Fig. 5, it is allocated to " automatically " position for the machine room inspection switch that the embodiment of the invention provides from " maintenance ", and the gate interlock short circuit protection loop state figure of gate interlock loop when still being in the short circuit state.After elevator was fixed, during from " maintenance " state commentaries on classics " automatically " state, the maintainer forgot the terminals SMA of dismounting short unit SM and the shorting stub of SMB; Even gate interlock loop LC connects; Elevator is closed the door automatically, but because second switch JX2 and relief relay K switch all are off-state, whole loop is broken off; Therefore gate interlock relay K M dead electricity still, elevator still can't recover " automatically " and move.
Please refer to Fig. 6, it is allocated to " automatically " position for the machine room inspection switch that the embodiment of the invention provides from " maintenance ", and with the gate interlock short circuit protection loop state figure after the shorting stub dismounting.After elevator is fixed, when " maintenance " state changes " automatically " state, the maintainer through above-mentioned can't start the prompting of elevator after; Remove the terminals SMA of short unit SM and the shorting stub of SMB, the relief relay K switch is a closure state, and the loop is connected; Gate interlock loop LC connects; Elevator is closed the door automatically, and gate interlock relay K M gets electric, and elevator recovers " automatically " operation.
In sum, the present invention provides a kind of elevator door interlocking short circuit protection loop, breaks off when elevator door interlock circuit failover, causes the gate interlock relay electric-loss; Thereby when making elevator out of service, the repair and maintenance personnel can have the gate interlock of special sign to protect the short circuit terminal through on-the-spot short circuit according to operation instructions, are about to the short unit two ends and connect with lead; Realize " maintenance " operation, remove shorting stub behind the trouble-shooting, recover elevator " automatically " operation; If but because of maloperation or forget the shorting stub of dismantling, made said gate interlock loop still keep the short circuit state, after elevator would recover " automatically " state; The machine room inspection switch is all closed, because said relief relay is being controlled the closed or disconnection of said relief relay switch, therefore; In short circuit gate interlock loop, when being about to the short unit two ends and connecting with lead, relief relay be in electric conducting state; Control said relief relay switch and break off, make the disconnection of said gate interlock relay and loop, cause the gate interlock relay dead electricity that remains unchanged; Thereby make elevator out of service, forcibly remind professional repair and maintenance personnel to remove shorting stub, guarantee elevator safe operation under " automatically " state.This loop structure is simple, is easy to set up, and cost is low, has but guaranteed equipment and personnel's safety to a great extent.
