Fig. 2 is the treatment scheme of the earthquake controlled operation of elevator of one embodiment of the invention.
Earthquake has taken place in step 201, has judged in step 202 whether the earthquake sensing device of ultralow grade moves.When sensor does not move, enter and continue normal operation in the step 203.
When the earthquake sensing device of ultralow grade has carried out action, at first, in step 204, make the bright lamp of earthquake controlled lamp, and check in step 205 whether low-grade earthquake sensing device moves.If low-grade earthquake sensing device does not move, then enter step 206, if elevator is just under steam, then in step 207, confirm the position of its service direction and lift car.Meanwhile, in step 208, whether the displacement of regulation and the relation between described service direction and the elevator car position have taken place according to each long size members, with reference to the judgment data table that preestablishes and store, safety when inspection is travelled under this state makes elevator move towards nearest floor simultaneously.When not detecting any long size members the regulation displacement taken place, even and the long size members that detects a part displacement of stipulating has taken place, but still can continue to travel safely the time, in step 209, make elevator parking on nearest floor.After this, the same with Fig. 4 (a) part, elevator door opened allow the passenger leave lift car, after this elevator door cuts out and enters readiness for action, at the appointed time, the earthquake sensing device of ultralow grade is resetted, make elevator recover normal operation.
Continue to travel in the time of to cause danger if in step 208, be judged as, enter step 210, elevator emergency is stopped, in step 211, inform that the passenger in the lift car will change the service direction of elevator, and the situation of elevator is informed the passenger.After this, in step 212, confirm the position of lift car, the service direction of elevator is transformed into opposite sense, and in step 213, carries out low cruise, in step 214, confirm to continue to travel be safe in, elevator is stopped to nearest floor.Continue to travel when dangerous if in step 214, be judged as, then be judged as and terrific situation occurs, elevator is stopped and entering run-stopping status.
Below to described step 208,214 and same steps as described later 220 and 231 etc. in the judgement determination methods that continues to travel whether can cause danger the time describe.
Fig. 3 represents the judgement data sheet in one embodiment of the invention, when detecting main hoist cable 5, speed controller rope 7, stern fast 6 and balance rope 11 as long size members the displacement (winding) of regulation has taken place, uses this judgement to judge with data sheet.When the detecting device 12～20 by each regulation displacement shown in Figure 1 detects each long size members the displacement of regulation has taken place, position and travel direction thereof according to lift car 2, detection is expressed as " effectively " being judged as when dangerous, and detection is expressed as engineering noise being judged as when being safe from danger.Fig. 3 is shown in Figure 1 in bottom suspention lift car (underslung elevator) and the judgement data sheet that adopted the elevator of 2: 1 hoist cable method for winding to use.Can know from Fig. 3, judge with in the data sheet at this, whether the top that is currently located at intermediate floor according to lift car is the current service direction of below and lift car still, can counteract current the travelling of lift car the displacement of described long size members and set.Except stern fast 6, how the judgement of main hoist cable 5, speed controller rope 7 and balance rope 11 and the position of lift car have nothing to do, and only judge according to service direction.
In the determining step of Fig. 2 " continue whether dangerous travel ", when any detecting device that is used for detecting the detecting device 12～20 that whether has carried out the regulation displacement is judged as " effectively " hurdle that belongs to Fig. 3 according to current elevator car position and service direction thereof, then represent "Yes", just dangerous.
Turn back to Fig. 2, in step 205, when the shake doughtily that low-grade earthquake sensing device also moves has taken place, in step 216, whether just under steam to confirm elevator, and in step 217, check and have or not the fast running zone.If the fast running zone is arranged, confirm in step 218 then whether lift car is positioned at the position that can be accommodated to certain floor after travelling about 10 seconds.If in this scope, then in step 219, confirm the service direction of elevator and the position of lift car.Meanwhile, in step 220, whether the displacement of regulation and the relation between described service direction and the elevator car position have taken place according to each long size members, and judgment data table with reference to the Fig. 3 that preestablishes and store, in the safety when inspection continues to travel, make elevator towards nearest floor operation.When not detecting any one long size members the displacement of regulation has taken place, even perhaps detect the long size members of a part displacement of stipulating has taken place, but still can continue to travel safely the time, elevator has been stopped to nearest floor.After this, the same with Fig. 4 (b) part, inform the situation of elevator to the passenger of lift car, open elevator door and allow the passenger leave elevator, after this, close elevator door, and make elevator out of service under halted state.
If the judged result of step 218 is a "No", and near do not have to stop floor the time, enter in the step 222, elevator emergency is stopped.After this, confirm in step 223 whether the circuit relevant with elevator safety be normal.If the circuit relevant with elevator safety taken place unusually, then be judged as the terrific state of appearance, even out of service at step 224 neutrality elevator.
If confirm that in step 223 circuit relevant with elevator safety is normal, and confirm that in step 225 high-grade earthquake sensing device less than when bigger rocking having taken place move, enters step 226.In step 226, after having carried out about about one minute standby, make lift car towards the direction low speed driving that leaves counterbalanced weight 3, after this, as mentioned above, in the safety of confirming travel direction, make elevator parking at nearest floor.
If when in step 225, confirming high-grade earthquake sensing device and moving because of bigger rocking taken place, the same with (c) part of Fig. 4, under professional's guidance, take emergency measures by the rescue personnel.
In addition, in driving to the way of nearest floor, continue to travel in the time of to cause danger if in step 220, be judged as, elevator emergency is stopped, the service direction of informing the passenger elevator in the lift car in step 228 will be converted to opposite sense, and the situation of elevator is informed the passenger.Afterwards, in step 229, confirm elevator car position, service direction is converted to opposite sense, in step 230, carry out low cruise, in step 231,, in step 221, make elevator parking arrive nearest floor having confirmed to continue to travel when being safe.If in step 231, be judged as when continuing to travel danger, then be judged as and terrific state occurs, elevator is stopped and entering run-stopping status.
According to this embodiment, when detecting main hoist cable 5, speed controller rope 7, stern fast 6 and balance rope 11 as long size members the displacement of regulation taken place, judge whether this displacement is dangerous to continuing to travel, elevator emergency is stopped when dangerous being judged as, thus, can avoid causing danger.In addition, be converted to opposite sense with the service direction of elevator this moment, and make the elevator low cruise, confirming to continue to travel when being safe, lift car stopped to nearest floor, thus, can significantly reduce the situation that the passenger is closed in the lift car and take place.
In addition, in Fig. 1, be that example is illustrated with the occasion of 2:1 winding method, even but adopt other hoist cable winding method, as long as by the part of main hoist cable 5 suspentions the winding detecting device is installed at lift car 2 and counterbalanced weight 3, just can be accessed same effect.In addition, the present invention can certainly be applied in winch 4 and not be arranged in the elevator that is provided with the Machine Room in the hoist trunk 1.
