When elevator comes downwards to extreme position, the limit spacing switch S4 under normally off is disconnected, and disconnects elevator safety loop, elevator stops
Only run.
It is to control ascending for elevator after limit spacing switch disconnects that uplink, which enables combined finger 202,.The enabled combination branch of uplink
Routing car top calling uplink branch 205, control cabinet calling uplink branch 203 and outer-office calling uplink branch 204 in parallel form,
After any uplink branch conducting, elevator safety loop conducting, elevator can call uplink.
Car top calling uplink branch 205 is controlled by car top uplink button U1, public end button C and car top overhauling switch TCI
System conducting, car top overhauling switch TCI is closed, and presses car top uplink button U1 and public end button C simultaneously, and operator can be
Car top calls ascending for elevator.
Have in control cabinet calling uplink branch 203 and is in series with normally closed car top overhauling switch TCI and urgent electric operation is opened
Close ERO, after elevator comes downwards to extreme position, limit spacing switch S4 disconnect, and not operating car top overhauling switch TCI with promptly
When electric operation switch ERO, control cabinet calls uplink branch 203 to be connected automatically, elevator safety loop is connected, by control system
Automatic-calling ascending for elevator.
Outer-office calling uplink branch 204 is examined by uplink button U2, urgent electric operation switch ERO outside the Room and normally closed car top
Repair switch TCI control conducting.It is closed in urgent electric operation switch ERO, car top overhauling switch TCI is disconnected, and it is outside upper to press the Room
Row button U2, outer-office calling uplink branch 204 are connected, and elevator can call uplink.
Car top overhauling switch TCI is equipped in car top and control cabinet, and the two is synchronous, wherein car top overhauling is opened at one
After closing TCI movement, the car top overhauling switch TCI of another place position also executes identical movement.
Electrical system in the present embodiment has the downlink signal detection branch 300 of access elevator safety loop, the branch
It is connected in elevator downlink and issues signal.In downlink signal detection branch 300, normally closed detection limit switch S5 and pit are vertical
Lever switch S3 series connection.Detection limit switch S5 is mounted on the top of limit spacing switch S4, and downlink signal detection branch 300 is in sedan-chair
Compartment is connected after not touching detection limit switch S5 and pit upright bar switch S3 standing, issues signal.
Electrical system in the present embodiment further includes Signalized control circuit 400 and signal lamp instruction circuit 500.Signal lamp
By pit door interlock switch S1, pit upright bar switch S3, the first relay KM1 and the second relay KM2 group in control loop 400
At the coil of the first relay KM1 and normally closed pit door interlock switch S1 are composed in series the first branch, the second relay KM2's
Coil and normally opened pit upright bar switch S3 are composed in series second branch, and the first branch and second branch are connected in parallel on Signalized control
In circuit 400.
Signal lamp instruction circuit 500 includes that the first red light instruction branch, the second red light instruction branch and green light in parallel refer to
Show branch.The normally-closed contact K1 of first relay, the normally-closed contact K2 of the second relay and red indicating light L1 are composed in series
One red light indicates branch.Pit bending switch S2, the second relay normally-closed contact K2 and red indicating light L1 be composed in series
Two red lights indicate branch.The normally opened contact K2 and green indicator light L2 of second relay KM2 is composed in series green light instruction branch.
When elevator needs to overhaul downlink, operator needs to open bottom hall door, and pit door interlock switch S1 is disconnected, and enters
Pit erects pit bending switch S2 and pit upright bar switch S3 respectively.After pit door interlock switch S1 disconnection, the first relay
The coil no power of KM1, the first red light indicate that two contacts in branch remain closed.After erecting pit upright bar switch S3, pit
Upright bar switch S3 is connected with the second branch that the coil of the second relay KM2 forms, and the first red light indicates branch and the second red light
Indicate that two normally-closed contact K2 of the second relay KM2 in branch are disconnected, and the second relay KM2 in green light instruction branch
Two contact closures, make green light instruction branch conducting, pit indicator light green light lights, can be with normal service downlink.
Electrical system in the present embodiment further includes the pit for resetting electromagnet 700 and pit door interlock switch S1 and being composed in series
Door interlock switch resets branch 600, resets electromagnet 700 and is triggered by the key of pit hall door door lock.When entering pit, door is rotated
Lock key resets electromagnet 700 and is powered, pit door interlock switch is driven to disconnect；When closing pit hall door, door keys are rotated, it is multiple
Position electromagnet is powered, and drives pit door interlock switch closure.
As shown in Figure 1, open pit hall door and erect the upright bar in pit, pit door interlock switch S1 and pit bending switch
S2 is disconnected, and disconnects elevator safety loop, elevator is not normally functioning, and can carry out car top overhauling.
As shown in Fig. 2, opening pit hall door, the first branch in Signalized control circuit is disconnected, the first red light instruction branch
Road is held on, and red indicating light is bright.Elevator safety loop in Fig. 1 disconnects, and elevator is not normally functioning, and erects pit upright bar
Switch S3, the second branch conducting in Signalized control circuit, the first red light indicate branch and the second red light instruction branch simultaneously
It disconnects, green light indicates branch conducting, gives a green light, while accessing the downlink signal detection branch conducting of elevator safety loop, elevator
It can normal downlink.When carriage downlink touches limit spacing switch 201, elevator safety loop and downlink signal detection branch
It disconnects, elevator is unable to downlink at this time, but can be with uplink.It acts the car top that uplink enables in combined finger 202 and calls ascending branch
Road 205 or outer-office calling uplink branch 204, turn it on, can control ascending for elevator.
When resetting elevator, pit bending switch S2 and pit upright bar switch S3 are needed to be reset, then operator goes out bottom
Hole, and pit door interlock switch S1 is resetted by resetting electromagnet 700 using key, red indicating light goes out, and indicates that elevator is reset to
Function.
For the present embodiment suitable for shallow pit vertical lift, operator, which overhauls downlink, must go pit to open pit bending
It closes and pit upright bar switch is opened, increase safety.
According to the disclosure and teachings of the above specification, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula carries out change and modification appropriate.Therefore, the invention is not limited to the specific embodiments disclosed and described above, to this
Some modifications and changes of invention should also be as falling into the scope of the claims of the present invention.In addition, although this specification
