The specific embodiment
Below, describe the present invention in order more specifically to explain with reference to accompanying drawing.In addition, in each accompanying drawing,, and suitably simplify or omit its repeat specification the identical label of identical or cooresponding part mark.
Fig. 1 is the constructional drawing of earthquake recovery apparatus of the elevator of expression embodiment 1 of the present invention.In Fig. 1, the hoistway of the elevator in the building 2 is located in 1 expression, and the elevator(lift) machine room of hoistway 1 top is located in 3 expressions.4 are illustrated in the car of up-down in the hoistway 1, and 5 are illustrated in the hoistway 1 interior counterweight that oppositely goes up and down each other with car 4, and 6 represent to hang with the transfusion bottle mode the main rope of car 4 and counterweight 5.The driving rope sheave of the towing machine in the machine room 3, the part of its main rope 6 of reeling are located in 7 expressions.
The accelerograph that machine room 3 is located in 8 expressions is the S wave detector, is used to detect the lateral shake that results from building 2.In this S wave detector 8, will be set at two grades (low-grade rank, high-grade ranks) with the acceleration/accel rank of the cooresponding building lateral vibration of the height of building 2 (S wave detector 8 be provided with height).And, constituting when the acceleration/accel that detects with the cooresponding building lateral vibration of each rank, 8 actions of S wave detector are the output prearranged signal also.
The accelerograph that 9 expressions detect the acceleration/accel of the up-down vibration that results from building 2 is the P wave detector, and it is arranged in the melt pit of hoistway 1.This P wave detector 9 moves through the acceleration/accel of the up-down vibration of detection intended level, and the output prearranged signal.
The phugoid detector of machine room 3 is located in 10 expressions.This phugoid detector 10 constitutes cord traverse shake detecting devices, is used for detecting the lateral shake amount of the rope that uses at elevator (main rope 6, not shown compensates rope and speed controller rope etc.).Specifically, phugoid detector 10 detects the lateral vibration that results from building 2, estimates that according to this testing result (calculating) has produced the amplitude (lateral amplitude of vibration) of the rope of lateral shake.In addition, this phugoid detector 10 is provided with for the lateral shake that detects the rope that when high wind and long period earthquake take place, produces, and it constitutes also can detect slowly shaking of the building 2 of being failure to actuate as S wave detector 8.
And; The grade setting that this phugoid detector 10 constitutes the lateral amplitude of vibration of rope is two grades (low-grade rank (Lv1), high-grade ranks (Lv2)); When the lateral amplitude of vibration that detects with the cooresponding rope of each rank, 10 actions of phugoid detector are the output prearranged signal also.
The control setup of machine room 3 is located in 11 expressions; Have following function: except that the common running of elevator, the various runnings of the controlled operation automatic diagnosis running after the earthquake controlled running of the controlled operation when also controlling earthquake, phugoid controlled operation and the earthquake.Specifically; Control setup 11 has the 1st handling part 12 of the earthquake controlled running of control, the 2nd handling part 13 of control automatic diagnosis running and the 3rd handling part 14 of control phugoid controlled operation; According to signal from S wave detector 8 and P wave detector 9 and 10 inputs of phugoid detector, the various controlled operations after the control setup 11 control earthquakes.
Below, the concrete action of the earthquake recovery apparatus of the elevator with said structure is described according to Fig. 2～Fig. 4.Fig. 2 is the diagram of circuit of action of earthquake recovery apparatus of the elevator of expression embodiment 1 of the present invention, and Fig. 3 and Fig. 4 are the figure of action of earthquake recovery apparatus that is used to explain the elevator of embodiment 1 of the present invention.
In elevator, if even earthquake P wave detector 9 takes place also is failure to actuate, then continue to turn round usually (S101～S103).On the other hand, when P wave detector 9 moves owing to the generation of earthquake (S102, " being "), then, judge that in elevator S wave detector 8 has attonity (S104).At this, when S wave detector 8 does not detect low-grade other acceleration/accel of level (below be also referred to as " the low-grade detection "), make elevator (car 4) stop nearest floor, make the passenger walk out this stop, making running stop certain hour (S105 and S106) then.Then, after S106 makes elevator stop certain hour, confirming to make elevator revert to common running (S103) when shaking of earthquake calmed down.
And S wave detector 8 carries out low grade when surveying in S104, judges then whether S wave detector 8 detects high-grade other acceleration/accel of level (below be also referred to as " the high-grade detection ") (S107).At this, when S wave detector 8 carries out the top grade detection, because the possibility of the bigger infringement of elevator generation is bigger, so judgement reverts to common running hazardous automatically.That is, make the nearest floor of elevator parking, make the passenger walk out this stop, elevator is shut down up to professional and technical personnel's manual spot check end (S108 and S109).
On the other hand; When S wave detector 8 does not carry out the top grade detection in S107; Even think that elevator does not produce earthquake damage or produced earthquake damage also is slight, so implement to be used under predetermined condition, making elevator to revert to the automatic diagnosis running of common running automatically.Specifically, at first make the nearest floor of elevator parking, make the passenger walk out this stop, make running stop certain hour (S110 and S111) then.
In addition, as shown in Figure 7, in the action of in the past earthquake recovery apparatus, in S411, make elevator stop certain hour after, confirm that shaking of earthquake calm down, and under this state, begin the automatic diagnosis running.
By contrast, in the action of this embodiment,, change the action of automatic diagnosis running according to lateral shake amount by the detected rope of cord traverse shake detecting device.That is, when earthquake, cord traverse shake detecting device detects the lateral shake amount of rope.And, confirm after making elevator stop certain hour in S111 that when shaking of earthquake calmed down according to the lateral shake amount by the detected rope of cord traverse shake detecting device, judgement could be implemented automatic diagnosis running (S112).
Specifically; Judge that phugoid detector 10 has attonity; When phugoid detector 10 detects the cord traverse shake amount of high-grade rank (Lv2),, be judged as and produce equipment damage and rope in the hoistway 1 to collude the possibility of extension bigger according to the lateral shake that results from elevator rope.In this case, do not implement the automatic diagnosis running, and elevator is shut down up to professional and technical personnel's manual spot check end (S109).
On the other hand; In S112; When phugoid detector 10 does not detect the cord traverse shake amount of high-grade rank (Lv2), be judged as and do not produce equipment damage and the rope that the lateral shake because of rope causes and collude extension, even implement the automatic diagnosis running infringement of elevator is enlarged.That is, beginning automatic diagnosis running (S113) makes elevator revert to common running (S114) according to this diagnostic result.Specifically,, then stop diagnosis operation, elevator is shut down up to professional and technical personnel's manual spot check end (S109) at once if in the automatic diagnosis running, detect certain abnormal elevator.On the other hand, unusual if the automatic diagnosis running finishes all not detect, then begin common running (S103) once more.
In addition, as stated, the lateral shake of the rope that phugoid detector 10 produces when in order to detect high wind and long period earthquake taking place is provided with.Therefore, be failure to actuate and under the situation of phugoid detector 10 actions, control setup 11 (the 3rd handling part 14) is implemented and the cooresponding phugoid controlled operation of its output rank at P wave detector 9 and S wave detector 8.For example, make the nearest floor of elevator parking, make the passenger walk out this stop after, make car 4 move to elevator be not vulnerable to phugoid influence the desired location, be the such action in position that rope does not resonate.
Below, according to Fig. 3 and Fig. 4, specify the action example of S wave detector 8 and phugoid detector 10.
Fig. 3 is illustrated among the S112 among Fig. 2 the action example when being judged as " denying ".Shake because of earthquake etc. at building 2, and the acceleration/accel of this building 2 is when surpassing the low-grade rank that S wave detector 8 is set, S wave detector 8 is made as ON to the output of S ripple (low).On the other hand, as shown in Figure 3, the lateral shake amount of rope reaches peak swing and compares the moment of the peak swing of the acceleration/accel that detects building 2 in time and lag behind a little.Therefore, about the action rank of phugoid detector 10, even the lateral shake that produces rope also not the grade setting of impedimenta be Lv1,, prediction rope meeting big lateral shake is Lv2 with the grade setting that hoistway 1 interior equipment contacts.
Under situation shown in Figure 3, in the moment of the peak swing that detects the cord traverse shake amount, 10 of phugoid detectors are made as ON with Lv1.Therefore, be judged as and do not have obstacle, elevator to change automatic diagnosis running action over to advancing of elevator.
On the other hand, identical with situation shown in Figure 3 about S wave detector 8 in Fig. 4, only the output with S ripple (low) is made as ON, but about phugoid detector 10, Lv1 and Lv2 both sides is made as ON.Therefore, wait infringement owing to predict extensions that collude of rope, to change the automatic diagnosis running over to and elevator is advanced be dangerous so be judged as, and turns round and be in the state of shutting down thereby make elevator not change automatic diagnosis over to.
According to the embodiment of the present invention 1; When the rope that makes elevator owing to shaking of earthquake produces lateral shake; Suitably change the action of automatic diagnosis running according to the lateral shake amount of this rope, thereby can prevent reliably because of implementing the infringement expansion that diagnosis operation causes.That is, confirm the movement content (could implement) of automatic diagnosis running,, can prevent to change over to automatic diagnosis reliably and turn round so collude when hanging etc. might producing equipment damage and rope at this embodiment middle finger according to the output rank of phugoid detector 10.Therefore, the secondary damage of advancing and causing can be prevented reliably, the recovery as early as possible of the elevator after the earthquake can be realized because of the elevator after the earthquake controlled running.And, infringement is suppressed to Min., so help the life-span of elevator to prolong.
In addition, in this embodiment, the situation of phugoid detector 10 as the cord traverse shake detecting device of the lateral shake amount that detects the rope that in elevator, uses of using has been described.But,, then can be any structure as long as this cord traverse shake detecting device has above-mentioned functions.For example, also can constitute in hoistway 1 photographic camera is set, directly measure the lateral shake that results from rope.
But when as this embodiment, using phugoid detector 10 as cord traverse shake detecting device, the system of the high price in the time of need not using above-mentioned photographic camera can make up the system of the low-cost and high-precision that uses existing device.
Fig. 5 is the diagram of circuit of action of earthquake recovery apparatus of the elevator of expression embodiment 2 of the present invention.Following situation has been described in embodiment 1; With the detection grade setting of phugoid detector 10 is two grades (low-grade rank (Lv1), high-grade ranks (Lv2)); After earthquake; When phugoid detector 10 detects the cord traverse shake amount of high-grade rank (Lv2), do not implement changing over to the automatic diagnosis running.The following situation of explanation in this embodiment, when implementing the automatic diagnosis running, according to by the detected cord traverse shake amount of cord traverse shake detecting device, the gait of march of the elevator when changing diagnosis operation (below be also referred to as " diagnosis speed ").
Specifically, for phugoid detector 10 grade setting of cord traverse shake amount is many grades.And phugoid detector 10 moves through detecting with the cooresponding cord traverse shake amount of each rank, and the output prearranged signal.
In Fig. 5, show the action when the detection grade setting of cord traverse shake amount being this fourth gear of Lv1～Lv4 for phugoid detector 10 as an example.At this, Lv4 representes the rank that the cord traverse shake amount is maximum, is set to the rank that increase might contact with the equipment in the hoistway 1 of shaking of rope.That is, Lv4 is equivalent to the Lv2 in the embodiment 1.
Therefore, in S211, make elevator stop certain hour after, when confirming that shaking of earthquake calmed down, control setup 11 has been imported the actuating signal of Lv4 according to whether from phugoid detector 10, judge and could implement automatic diagnosis running (S212).Promptly; Judge that in S212 phugoid detector 10 has attonity; When phugoid detector 10 detects the cord traverse shake amount of Lv4; Be judged as implement the automatic diagnosis running be dangerous, promptly might enlarge infringement, thereby the manual spot check that elevator is shut down up to the professional and technical personnel finishes (S209).
On the other hand, when phugoid detector 10 does not detect the cord traverse shake amount of Lv4 in S212, be judged as and equipment damage and rope that the lateral shake because of rope causes do not take place collude extension, then, carry out the setting (S213) of diagnosis speed.In addition, as stated, be set with the rank Lv1～Lv3 that is lower than Lv4 for phugoid detector 10.At this; Lv1～Lv3 representes the size of the lateral shake amount of rope, and for example, Lv1 is set to the rank that rope shakes hardly; Lv2 is set to the small rank of shaking of rope, and Lv3 is set to the rank that the rope that do not cause the degree of obstacle to advancing significantly shakes.
In S213, control setup 11 changes to diagnosis speed and the cooresponding speed of the testing result of phugoid detector 10.That is, when 10 of phugoid detectors detect Lv1, think to produce the equipment and the infringement of rope in the hoistway 1 hardly, so the quickening diagnosis speed makes elevator can revert to common running fast.The quickening diagnosis speed on the other hand, when detecting Lv3,, may produce the winding of rope, so if might produce the secondary damage of rope damage etc. though not think and to produce contacting of equipment in rope and the hoistway 1 because of earthquake.Therefore, when in diagnosis operation, detecting when unusual, gait of march is set at low speed, so that can stop to advance of elevator at once.
And, in S213, carried out the setting with the cooresponding diagnosis speed of cord traverse shake amount after, according to the diagnosis speed that sets, begin to make elevator to revert to the automatic diagnosis running (S214) of common running.
Other structures are identical with embodiment 1 with action.
In embodiment 2 of the present invention, according to the lateral shake quantitative change of rope diagnosis speed more.Therefore, produce the possibility of infringement when bigger, can diagnosis speed be made as low speed, in the automatic diagnosis running, detect when unusual, can make rapidly to advance to stop at elevator.Its result can prevent when in diagnosis operation, detecting unusual and elevator is stopped, also can finish resuming operation based on manual spot check fast because of implementing the secondary damage that diagnosis operation causes reliably.
On the other hand, when the possibility of elevator generation infringement is smaller, can diagnosis speed be made as at a high speed, can shorten the needed time of diagnosis operation.Its result can revert to common running as early as possible, can improve the service of elevator.
Other effects are identical with embodiment 1.
Fig. 6 is the diagram of circuit of action of earthquake recovery apparatus of the elevator of expression embodiment 3 of the present invention.Following situation has been described, when implementing the automatic diagnosis running, according to changing diagnosis speed by phugoid detector 10 detected cord traverse shake amounts in embodiment 2.The following situation of explanation in this embodiment when implementing the automatic diagnosis running, according to by the detected cord traverse shake amount of cord traverse shake detecting device, changes the running content (diagnosis content) of diagnosis operation.
Specifically, identical with embodiment 2, for phugoid detector 10 grade setting of cord traverse shake amount is many grades, from 10 outputs and the cooresponding predetermined actions signals of each rank of phugoid detector.
In Fig. 6, show the action when the detection grade setting of cord traverse shake amount being this third gear of Lv1～Lv3 for phugoid detector 10 as an example.At this, Lv3 representes the rank that the cord traverse shake amount is maximum, is set to the rank that increase might contact with the equipment in the hoistway 1 of shaking of rope.That is, Lv3 is equivalent to Lv2 and the Lv4 in the embodiment 2 in the embodiment 1.
Therefore, in S311, make elevator stop certain hour after, confirming when shaking of earthquake calmed down control setup 11 has been imported the actuating signal of Lv3 according to whether from phugoid detector 10, judge and could implement automatic diagnosis running (S312).Promptly; Judge that in S312 phugoid detector 10 has attonity; When detecting the cord traverse shake amount of Lv3 by phugoid detector 10; Be judged as implement the automatic diagnosis running be dangerous, promptly might enlarge infringement, thereby the manual spot check that elevator is shut down up to the professional and technical personnel finishes (S309).
On the other hand, when phugoid detector 10 does not detect the cord traverse shake amount of Lv3 in S312, be judged as and equipment damage and rope that the lateral shake because of rope causes do not take place collude extension, then, carry out the setting (S313 and S314) of diagnosis content.In addition, as stated, be set with rank Lv1 and the Lv2 that is lower than Lv3 for phugoid detector 10.At this, Lv1 and Lv2 represent the size of the lateral shake amount of rope, and for example, Lv1 is set to that shaking of rope is little, the equipment in the hoistway 1 and the slight rank of infringement of rope, and Lv2 is set to that shaking of rope is big, the rank of the winding that predicts rope etc.
In S313 and S314, control setup 11 changes to diagnosis content and the cooresponding content of the testing result of phugoid detector 10.Promptly; When Lv1; Not think to produce because of the winding of rope and collude the change of hanging the rope tension that produces,, for example detect abnormal sound that the shakiness owing to safety switch and guiding device (lead and support boots etc.) produces etc. so be slight bad of a spot check with diagnotic content setting.On the other hand, when Lv2, think rope tension might because the winding of rope and colluding hang and wait and change, so include the scale device of car 4 and the torque current of towing machine in checkup item, enforcement failure-free spot check.
And, in S313 and S314, carried out the setting with the cooresponding diagnosis content of cord traverse shake amount after, according to the diagnosis content that sets, begin to be used to make elevator to revert to the automatic diagnosis running (S315) of common running.
Other structures are identical with embodiment 1 with action.
In embodiment 3 of the present invention, change diagnosis content according to the lateral shake amount of rope.Therefore, produce the possibility of infringement when bigger, include whole projects of planning in checkup item, can carry out reliable diagnostic at elevator.Its result can prevent when in diagnosis operation, detecting unusual and elevator is stopped, also can finish resuming operation based on manual spot check fast because of implementing the secondary damage that diagnosis operation causes reliably.
On the other hand, when the possibility of elevator generation infringement is smaller, N/R project in the planning item can be omitted, the needed time of diagnosis operation can be shortened.Its result can revert to common running as early as possible, can improve the service of elevator.
In addition, in this embodiment, the situation that only changes diagnosis content according to the cord traverse shake amount has been described, but also can have been changed diagnosis content and diagnosis speed simultaneously.
Other effects are identical with embodiment 1.
