The shallow pit elevator electrical safety circuit fallen.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of shallow pit elevator electrical safety circuit, the safety return circuit control circuit including being in series with several safety switches,
It is characterized by: being also in series with electrical safety reset switch, electric safety switch, electrical peace in the safety return circuit control circuit
Full connected device, it is removable only stop retract switch, it is removable only stop step switch and only stop to act contactor, it is described only to stop movement and connect
Tentaculum and electrical safety contactor, which are also connected, accesses to maintenance loop control circuit；The electric safety switch and electrical safety connect
Tentaculum is arranged in series；
It is described it is removable only stop retract switch or/and it is removable only stop step switch with only stop movement contactor and connect to set
It sets；
The removable only stop device switchs and only stops movement contactor and is arranged in series.
The hall door of the electric safety switch and elevator is correspondingly arranged.
It is described removable only to stop retract switch, removable only stop step switch and be arranged in the melt pit of elevator.
The electrical safety reset switch, electrical safety contactor and only stops to act contactor and be arranged at the control of elevator
In cabinet.
The beneficial effects of the utility model are: it is reasonable in design, the operating status of elevator can be effectively controlled, avoids tieing up
Accident occurs for the personnel of repairing.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.

Only stop to act contactor (KDA1), installation site: control cabinet；
Safety switch (X1,, Xn), installation site: computer room, hoistway, melt pit, in sedan-chair, car top etc., including control flow emergency stop
Switch, phase sequence relay, electrothermal relay, governor switch, limit switch, breaking rope protecting switch, melt pit service chamber emergency stop switch,
Buffer switch, operation panel emergency stop switch, security window switch, safety gear switch, car top inspection box emergency stop switch etc.；
Urgent electronic upstream switch (FMS), installation site: control cabinet；
Urgent electronic downlink (FMX), installation site: control cabinet；
It overhauls upstream switch (DMS), installation site: car top case；
It overhauls downing switch (DMX), installation site: car top case；
Inspection switch (JX), installation site: car top case；
Urgent electric operation switch (DJ), installation site: control cabinet；
A kind of shallow pit elevator electrical safety circuit, the safety return circuit control circuit including being in series with several safety switches,
Electrical safety reset switch (AQF), electric safety switch (AQK), electrical peace are also in series in the safety return circuit control circuit
Full connected device (KAQ), removable stop stop retract switch (DA0), move and only stop step switch (DA1) and only stop to act contactor
(KDA1)；
The auxiliary contact for only stopping to act contactor (KDA1) and electrical safety contactor (KAQ), which are also connected, accesses to inspection
Loop control circuit is repaired, stopping as electrical safety contactor (KAQ) and only could when acting contactor (KDA1) simultaneously operation
Carry out inspection travel；Lower additional limit switch (DAS) is bumped against when inspection travel, elevator can only carry out upward operation,
Realize the defencive function of shallow pit.
The electric safety switch (AQK) and the hall door of elevator are correspondingly arranged.
Removable stop stops retract switch (DA0), moves and only stop the melt pit that elevator is arranged in step switch (DA1)
It is interior.
The electrical safety reset switch (AQF), electrical safety contactor (KAQ) and only stop to act contactor (KDA1) equal
It is arranged in the control cabinet of elevator.
As shown in figure 5, electric safety switch (AQK), electrical safety reset switch (AQF), removable only suspend back are opened
Close (DA0), it is removable only stop step switch (DA1), electrical safety contactor (KAQ), only stop to act contactor (KDA1), under it is attached
Add limit switch (DAS), toeguard retract switch (DB0), inspection switch (JX), urgent electric operation switch (DJ), urgent electricity
Dynamic upstream switch (FMS), urgent electronic downing switch (FMX), maintenance upstream switch (DMS), maintenance downing switch (DMX) and each
Safety switch (X1,, Xn) access safety return circuit control circuit；
As shown in figure 3, will only stop the auxiliary contact access inspection of movement contactor (KDA1), electrical safety contactor (KAQ)
Circuit is repaired, realizes the defencive function of shallow pit.
When maintenance personal enters pit by triangular key, it is mounted on electric safety switch in hall door (AQK) movement, peace
Full loop control circuit disconnects, and elevator is unable to operate normally, only can be carried out it is urgent it is electronic run up, maintenance personal enters pit
Afterwards, can control it is removable only stop step switch (DA1), to make only to stop to act contactor (KDA1) movement, elevator could be into
Row inspection travel；When overhauling elevator operation, run down to out of service when lower additional limit switch (DAS), elevator can only
It runs up, thus is avoided that in pit accident occurs for maintenance personal.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
Purpose technical solution, belong within the protection scope of the utility model.
