Description
Technical field
The present invention relates to when implementing earthquake behind the controlled operation, for make elevator once more entry into service and implementing diagnose the diagnosis rotating device and the diagnosis method of operation of the elevator of running.
Background technology
In having the elevator of earthquake detector, when detecting the shaking of earthquake, according to the scale (size of the acceleration/accel of building etc.) of this earthquake, controlled operation when implementing to be called as the earthquake that is intended to rescue the passenger of stopping nearest floor.In addition, according to the scale of earthquake, it is unusual that in the following situation certain takes place in the hoistway of elevator sometimes: the joint of car and counterweight getaway, guide rail produces distortion or rope class and cable class and is hooked on the thrust in the hoistway.Therefore, owing to shaking of earthquake elevator was taken place under certain unusual situation in the past, promptly detect under the situation of the above earthquake of pre-determined size, the elevator of said structure is in the running halted state after stopping nearest floor, and continues above-mentioned running halted state till the professional and technical personnel (elevator reparing person etc.) of elevator implements upkeep operation.
In this elevator, when being absorbed in the running halted state owing to earthquake,, make service ability significantly reduce to beginning to need considerable time till the normal operation once more.Therefore, recently in order to address the above problem, and in order to alleviate elevator reparing person's burden after the earthquake, a kind of elevator has been proposed, it is when earthquake behind the controlled operation, under predetermined condition, implement the not diagnosis running of the upkeep operation of the person of needing repairing, when in this diagnosis running, not noting abnormalities, elevator is recovered automatically.
In above-mentioned diagnosis running, after for example controlled operation finishes when earthquake,, make car at this stop again after standby a few minutes, the earthquake detector of at first resetting as the aftershock countermeasure.Then, car slow speed (hereinafter referred to as " low speed ") with than normal operation the time is advanced, carry out the action of specified devices class simultaneously and judge, detect unusual thus.For example, car low speed is advanced measure the torque current of elevator hoist simultaneously, and the measured value of this torque current is compared with the reference pattern of being scheduled to, when its difference surpasses defined threshold, be judged as unusual.

In above-mentioned diagnosis running, carry out abnormality juding according to the torque current of gear transmission winch.That is, in diagnosis running, after controlled operation finishes when earthquake,, make car at this stop again after standby a few minutes, the earthquake detector of at first resetting in order to tackle aftershock.Then, car low speed is advanced, measure the torque current of gear transmission winch simultaneously, and the measured value of this torque current is compared with the reference pattern of being scheduled to, when its difference surpasses threshold value, be judged to be unusual.The concrete structure of this diagnosis rotating device below is described.
In Fig. 1, the control setup of the integral body control of elevator is administered in 1 expression, has CPU 2 and memory storage 3.Memory storage 3 has elevator information storage part 4, obtains threshold value table storage part 5 and the selection threshold value storage part 6 that the scheme storage part constitutes by threshold value.In addition, in described elevator information storage part 4, store predetermined elevator information in advance.In addition, elevator information for example by the gear of the gear of winch than and the various information of these relevant these elevators such as diameter of efficient, driving rope sheave constitute.
In described threshold value table storage part 5, store threshold value in advance and obtain scheme.This threshold value obtain forecast scheme configuration for gear than at least one of this elevator information as variable, can obtain the scheme of a plurality of threshold values by the value that changes this variable.For example, obtain scheme as described threshold value and store following threshold value table, this threshold value table respectively the gear that is stored in the gear in the elevator information storage part 4 than and the diameter of efficient, driving rope sheave as variable, the threshold list the when value with each variable is become various typical value.And, in selecting threshold value storage part 6, store the threshold value that is suitable for this elevator most according to the selections such as specification (determining) of winch.That is, in the diagnosis running, use to be stored in the threshold value of selecting in the threshold value storage part 6, carry out the abnormality juding of torque current.
In the CPU 2 of control setup 1, be provided with the threshold value selection portion 7 and the abnormal signal test section 8 that constitute by the threshold value determination portion.Threshold value selection portion 7 is to be used for selecting (determining) unit at the threshold value of the torque current of winch, according to the elevator information that is stored in the elevator information storage part 4, select (determining) to be suitable for the threshold value of this elevator most in the threshold value table from be stored in threshold value table storage part 5.In addition, the threshold value of being selected by threshold value selection portion 7 is stored in the described selection threshold value storage part 6.Abnormal signal test section 8 is the unusual unit that are used for judging in the diagnosis running of implementing after the earthquake torque current.That is, when the difference of the measured value of the torque current when car low speed is advanced and predetermined reference pattern surpasses when being stored in the threshold value of selecting in the threshold value storage part 6, abnormal signal test section 8 detects to having unusually.
Below, the concrete grammar that is used for determining at the described threshold value of the torque current of winch is described.Fig. 2 is the brief configuration figure with elevator of gear transmission winch.In Fig. 2, the car of 9 expression elevators, 10 are illustrated in the hoistway and the counterweight of car 9 reverse liftings, 11 expression hanging bottle types hang the main rope of car 9 and counterweight 10, the driving rope sheave of the main rope 11 of 12 expression coilings, the electrical motor of 13 expression winchs, the gear (retarder) of 14 expression winchs.That is, described winch is represented the gear transmission winch.
At this, as shown in Figure 2, the torque of winch (electrical motor 13) side is being made as high-speed side torque T
H, the torque of the elevator side by gear 14 is made as low speed side torque T
LThe time, according to equilibrium of forces, both satisfy following relational expression.
Wherein, k represents the gear ratio of gear 14, and η represents the efficient of gear 14.
And, since earthquake shake the cable class takes place collude extension etc., when making low speed side generation load change F unusual, thinking this load change F and the high-speed side torque T that thereupon forms
HChange T
HFBetween relation when identical with above-mentioned formula (1), following relational expression is set up.
Wherein, r represents to drive the radius of rope sheave 12.
According to above-mentioned formula (2) as can be known, for according to high-speed side torque T
HChange T
HFDetect the load change F of low speed side, need k, η, each elevator information of r.That is, need in the elevator information storage part 4 of control setup 1, store the gear of gear 14 each elevator information in advance than the radius r of k and efficiency eta and driving rope sheave 12.And storage makes above-mentioned k, η, each elevator information of r threshold value table as variable threshold value selection portion 7 according to above-mentioned k, η, each elevator information of r in threshold value table storage part 5, selects the threshold value of the best from above-mentioned threshold value table.
And, also can constitute, obtain in threshold value and store the such relational expression of above-mentioned formula (2) in the scheme storage part in advance and obtain scheme, by threshold value determination portion computing high-speed side torque T as threshold value
HChange T
HFAnd acquisition is suitable for the threshold value of elevator.In addition, be used to obtain high-speed side torque T
HChange T
HFNeeded elevator information is installed the information formation that the back does not have change if only utilize at elevator, then also can be stored in the value that has calculated in the memory storage 3.Above-mentioned information is only represented an example, improves the abnormality detection precision of diagnosing in the running in order to obtain more concrete threshold value, certainly uses the elevator information outside the above-mentioned information.
Fig. 3 is the diagram of circuit of action of diagnosis rotating device of the elevator of expression embodiments of the present invention 1.Above-mentioned threshold setting function is for example implemented (S101, S102) before the action after elevator is installed.That is, before elevator action, storing predetermined elevator information in elevator information storage part 4 in advance, and obtain in the scheme storage part in advance in threshold value that storage threshold obtains scheme.And, obtain scheme according to elevator information of being stored and threshold value, determine to be suitable for the threshold value of this elevator, and be stored in the selection threshold value storage part 6.
And behind the beginning normal operation (S103) when detecting earthquake (S104), controlled operation when at first implementing earthquake makes car 9 stop at nearest floor (S105).Then, car 9 low speed are advanced, measure the torque current of winch simultaneously, and measured value and predetermined reference pattern are compared, when its difference surpasses the threshold value that is stored in the described selection threshold value storage part 6, be judged to be unusual (S106).In addition, the threshold setting function of S102 can be as mentioned above implemented after elevator is installed at once, also can be when the Maintenance and Repair behind the beginning normal operation or enforcement such as during the updating maintenance contract.
On the other hand, in above-mentioned formula (2), drive the radius r of rope sheave 12 and the gear of gear 14 and at elevator not change of back is installed than k, but the efficiency eta of gear 14 can be owing to a variety of causes changes after elevator is installed, this is known item.Especially adopt the gear transmission winch of turbine as gear 14, torque current is higher to the sensitivity of one day variation of ambient temperature and elevator operation conditions (crowded, free time etc.), and torque current can significantly change sometimes.
Fig. 4 and Fig. 5 represent the efficiency eta of general turbine and the relation between the coefficientoffriction.In Fig. 4 and Fig. 5, coefficientoffriction is subjected to the influence of the viscosity of the lubricating oil that turbine uses.Generally, if the temperature of lubricating oil rises, then coefficientoffriction reduces, if the temperature of lubricating oil descends, then coefficientoffriction increases.In power running shown in Figure 4, because the increase of the rising of ambient temperature and running number of times, the temperature of lubricating oil rises, coefficientoffriction reduces, thereby the efficiency eta of gear improves.In addition, said above-mentioned power running refers to the outbound course and the identical situation of direction that drives rope sheave 12 actual rotations of the torque of winch.For example, when 9 li of cars did not have the passenger, the running that elevator is descended was equivalent to power running.
On the other hand, in regeneration operating shown in Figure 5, because the increase of the rising of ambient temperature and running number of times, the temperature of lubricating oil rises, coefficientoffriction reduces, thereby the efficiency eta of gear descends.In addition, said above-mentioned regeneration operating refers to the outbound course and the different situation of direction that drives rope sheave 12 actual rotations of the torque of winch.For example, when 9 li of cars did not have the passenger, the running that elevator is risen was equivalent to regeneration operating.
Like this,, after installing, elevator also can change as the efficiency eta of the gear 14 of one of elevator information because of the operational situation of elevator and ambient temperature variation etc.Therefore, the change that also can consider efficiency eta waits to determine the threshold value of the torque current of winch.
In this case, status information detecting unit (not shown) is set, utilizes this status information detecting unit to detect the predetermined status information of elevator at CPU 2.In addition, said above-mentioned status information refers to be used to obtain after elevator is installed also the information of the elevator information (efficiency eta etc.) that changes because of environment etc.For example, the temperature of the lubricating oil of status information detecting unit detection of gear 14 uses is as above-mentioned status information.
And,, need be set at threshold value to the status information that detects by above-mentioned status information detecting unit and obtain a variable in the scheme for state information acquisition optimal threshold according to lubricating oil temperature etc.For example, when detecting lubricating oil temperature, being stored as the part that threshold value is obtained scheme according to the relational expression of above-mentioned lubricating oil temperature derivation efficiency eta etc. as the status information of elevator.Then, the threshold value determination portion according to be stored in elevator information in the elevator information storage part 4, by the detected status information of status information detecting unit be stored in the threshold value that threshold value obtains in the scheme storage part and obtain scheme, determine the optimal threshold of the current time of this elevator.
In addition, when adopting said structure, shown in the diagram of circuit of Fig. 6, the scheduled period before beginning to diagnose running after the earthquake, implement threshold value set-up function (S204～S207) more as required.For example, the scheduled period when earthquake behind the controlled operation, carry out the detection of the status information of elevator by the status information detecting unit, before beginning to diagnose running, obtain current efficiency eta etc.And, the current efficiency eta of being obtained etc. with before under the different situation of efficiency eta etc. during setting threshold, by threshold value determination portion calculated threshold once more, the threshold value that is suitable for state after the earthquake is stored in selects in the threshold value storage part 6.
And, because the setting of threshold value only is made as once,,, before the diagnosis running, determine threshold value according to detected status information etc. so also can carry out the detection of the status information of elevator in the scheduled period after the earthquake.Fig. 7 represents this action.
In addition, scheduled period when being illustrated in earthquake in Fig. 6 and Fig. 7 behind the controlled operation is detected the situation of the status information of elevator, but the detection of this status information also can implemented after the earthquake at once, implements in the controlled operation during earthquake that can also be more abundant in time.In addition, more than show the efficiency eta of utilizing gear 14 and the example of the relation between the lubricating oil temperature, but in order to improve the abnormality detection precision in the diagnosis running, also can detect other status informations, various states information except that lubricating oil temperature, thereby obtain more concrete threshold value.
In addition, according to Fig. 4 and Fig. 5 as can be known,, opposite when power running and during regeneration operating with respect to the change of the efficiency eta of the change of coefficientoffriction.Therefore, also can constitute and obtain in the scheme storage part storage in threshold value and obtain scheme and obtain scheme, when the diagnosis running, use the threshold value that meets power running and regeneration operating with the corresponding threshold value of regeneration operating with the corresponding threshold value of power running.
According to the embodiment of the present invention 1, be used to judge unusual threshold value, the abnormality detection precision in the time of can significantly improving the diagnosis running in the time of can suitably being set in the diagnosis running according to the specification of elevator etc.For the gear transmission winch, the desired value of threshold value is more different with various elevator informations such as efficiency eta than k because of the gear of gear 14, so more suitable.In addition, also make in the gear transmission winch difficulty especially, implement whole abnormality detection accurately and become possibility.
In addition, if, then can when the diagnosis running, set appropriate threshold, so the abnormality detection precision can further improve the diagnosis running time utilizing the status information detecting unit to detect the predetermined status information of elevator after the earthquake.That is, when implementing the diagnosis running, can set the optimal threshold that meets the elevator state.
