Fig. 2 is the diagram of circuit of the processing method representing above-mentioned elevator.
First, when carrying out traction diagnosis to elevator 1, by carrying out remote operation from administrative center (not shown) or carrying out M/C by operating personnel, traction diagnostic device 12 is started.Then, from control setup 9, the rotation amount of winch coder 8 and the actual moving distance information of lift car 3 that determined by car moving distance measuring device 10 are sent to side-play amount computer device 13, in this side-play amount computer device 13, measure the side-play amount between main hoist cable 4 when running and rope sheave 6.Simultaneously, by control setup 9, the carrying capacity information of the lift car 3 determined by quality measuring apparatus in car 11 is sent to warp tension ratio computer device 14, and the warp tension ratio (step S1) when calculating operation according to the specification of the elevators 1 such as the quality of lift car 3 and the quality of counterbalanced weight 5 in this warp tension ratio computer device 14
After this, in limit tension prediction unit 15, calculate the warp tension ratio line of prediction 20 when measuring according to the side-play amount determined in step sl and the warp tension ratio that calculates, and the limit tension ratio (step S2) when calculating this mensuration.Then, by the limit tension calculated in this step S3 than comparing (step S3) with the maximum tension ratio in the specification limit of elevator 1.
Then, when this limit tension compares at maximum tension than time following, limit tension sends warning via warning device 18 to repair company than prediction unit 15, makes lift car 3 stop simultaneously, makes elevator parking arrive nearest landing (step S4) by control setup 9.Further, after this step S5, the passenger in notice lift car 3 leaves lift car 3.Become after zero in the carrying capacity of the measurement result confirmation lift car 3 according to quality measuring apparatus in car 11 because all passengers all have left lift car 3, close the door of lift car 3 at once, and, in order to avoid after this lift car 3 is running, CCE 9 forbids that elevator carries out running (step S5).
On the other hand, when the limit tension ratio calculated in step s 2 be greater than maximum tension than time, the limit tension calculated in step s 2 ratio and the side-play amount used in the calculating of this step S2 and warp tension ratio are stored and are kept at (step S6) in memory storage 16.After this, the operation conditions of limit tension ratio during mensuration according to the past be stored in this memory storage 16 and the carrying capacity from the range ability of starting at during the mensuration in past and when running for each time etc., as shown in Figure 3, in limit tension is than prediction unit 15, the limit tension of elevator 1 is generated than the line of prediction 22 (step S7).
After this, according to the operation conditions of the limit tension generated than prediction unit 15 by limit tension in this step S7 than the line of prediction 22 and elevator 1, calculate in limit tension is than prediction unit 15 and be predicted to be limit tension and namely change period 24 than by the period of the maximum tension ratio become in the specification limit being equal to or less than elevator 1 and between the current period of grace of starting at 25.Then, 25 will store and be kept at (step S8) in memory storage 16 respectively between replacing period 24 and period of grace.
Fig. 3 is the diagram of curves of the diagnostic result representing elevator.
Fig. 3 is X-Y scheme, and its X-direction represents warp tension ratio, and Y-direction represents side-play amount.Measurement result 19 shown in Figure 3 represents side-play amount that is corresponding with the warp tension ratio calculated by warp tension ratio computer device 14 when elevator 1 runs, that determined by side-play amount computer device 13 when elevator 1 runs.It should be noted that, a measurement result 19 is only shown in the drawings, and also multiple measurement result 19 can be shown as shown in Figure 3 simultaneously.
In addition, 20 in Fig. 3 represents in limit tension is than prediction unit 15 according to the warp tension ratio line of prediction that the warp tension ratio calculated by warp tension ratio computer device 14 and the side-play amount determined by side-play amount computer device 13 calculate.In figure 3, each measurement result 19 is labeled on the warp tension ratio line of prediction 20.In addition, 22 in Fig. 3 represents that the limit tension calculated as variation prediction line in limit tension is than prediction unit 15 according to the limit tension calculated before measuring the date 21 ratio be stored in memory storage 16 and side-play amount compares the line of prediction.And, figure 3 illustrates this limit tension than the line of prediction 22.
In addition, the intersection point of the specification maxim 23 of the permissible value of the warp tension ratio determined according to the specification of elevator 1 with expression than the line of prediction 22 by limit tension is considered as arriving the prediction period (namely changing period 24) of this specification maxim 23.And, using between the current period of grace as period of grace to changing period 24 25, figure to respectively illustrate between replacing period 24 and period of grace 25.In addition, the diagram of curves shown in Fig. 3 is exported in the mode of data or printed article as medical certificate by diagnostic result output unit 17.
As mentioned above, in the elevator 1 of the present embodiment, the main hoist cable 4 when side-play amount computer device 13 measures operation according to the rotation amount of winch coder 8 and the moving distance information of the reality of lift car 3 that determined by car moving distance measuring device 10 and the side-play amount between rope sheave 6.And, warp tension ratio when calculating operation according to the specification of the elevators 1 such as the quality of the carrying capacity information of lift car 3 that determined by quality measuring apparatus in car 11 and the quality of lift car 3 and counterbalanced weight 5 in warp tension ratio computer device 14, and, limit tension ratio when calculating mensuration according to above-mentioned side-play amount and warp tension ratio in limit tension prediction unit 15.Therefore, by confirming this limit tension ratio, limit tension ratio during mensuration can not only be predicted, but also this limit tension can be predicted than the period becoming specification value and the maximum tension ratio being less than elevator 1.
That is, when the limit tension calculated by this limit tension prediction unit 15 is than warp tension ratio when being equal to or less than the maximum load of elevator 1, the car 3 of this elevator 1 is in maximum load state.Thus, because of the factor such as abrasion of the rope sheave 6 beyond scope of design, operationally, the friction force between main hoist cable 4 and rope sheave 6 declines, and occurs main hoist cable 4 and relative state of skidding occurs between rope sheave 6.Now, must by controlling to avoid the limit tension calculated than prediction unit 15 by this limit tension than becoming the specification value being less than elevator 1.Thus, this limit tension is compared than with the maximum tension ratio in the specification limit of elevator 1, this limit tension ratio be equal to or less than maximum tension than time, send warning by warning device 18, and make lift car 3 out of service by the operation stop mechanism of control setup 9.
On the other hand, when the limit tension calculated by this limit tension prediction unit 15 than be greater than maximum tension than, illustrate that operationally main hoist cable 4 also relative skidding does not occur with between rope sheave 6, also do not reach replacing period.Calculated side-play amount than together with is stored in storage 16 with this limit tension with warp tension ratio.
In addition, the alteration of form of the groove that the groove coefficient between the main hoist cable 4 of elevator 1 and rope sheave 6 produces along with the abrasion because of rope sheave 6 and changing.In addition, this rope sheave 6 abrasion speed because of elevator 1 range ability and run time carrying capacity difference and be very different.To this, according to front once measure time limit tension than and this measures time limit tension ratio change, obtained by control setup 9 the mensuration from the past time range ability of starting at and each operation time the operation conditions of carrying capacity etc., in limit tension is than prediction unit 15, generate the line of prediction of limit tension ratio from now on and limit tension than the line of prediction 22.
Consequently, by confirming that the limit tension generated in limit tension is than prediction unit 15 is than the line of prediction 22 intersection point with the specification maxim 23 of elevator 1, can know in advance the parts such as rope sheave 6 grade of this elevator 1 replacing period 24 and between the current period of grace of starting at 25.Thus, according to 25 setting elevator 1 maintenance timings between this period of grace, can adjust the schedule that rope sheave 6 grade needs parts and the operating personnel changed in advance, thus significantly can reduce the upkeep operation of elevator 1 and the burden of schedule.Therefore, when the maintenance management operation carrying out elevator 1, can arrange from arranging according to the time to be converted to according to actual conditions.Further, when friction occurs the rope sheave 6 of elevator 1 or the friction coefficient between this rope sheave 6 and main hoist cable 4 has occurred declining, also can under the prerequisite can not damaging safety, elevator 1 be made to run.
In addition, according to the limit tension line of prediction 22 generated in limit tension is than prediction unit 15 and the operation conditions of elevator 1, calculate in limit tension is than prediction unit 15 rope sheave 6 grade replacing period 24 and between the current period of grace of starting at 25.Further, will 25 be kept in memory storage 16 between replacing period 24 and period of grace, exported the medical certificate recording between the limit tension line of prediction 22, replacing period 24 and period of grace 25 by diagnostic result output unit 17 in the mode such as data or printed article.
Consequently, the data exported by this diagnostic result output unit 17 by confirmation or printed article etc., limit tension can be grasped effectively than period of warp tension ratio when becoming the maximum load being greater than elevator 1, namely clearly and effectively can grasp the replacing period of rope sheave 6 grade of this elevator 1.Thus, compared with the situation at every turn calculating replacing period 24 than the line of prediction 22 according to the limit tension generated in limit tension is than prediction unit 15 with maintenance worker, frequency of maintenance can be reduced, therefore, it is possible to alleviate the burden of maintenance worker while shortening elevator 1 keeps in repair the required time.
In addition, limit tension than the limit tension ratio that prediction unit 15 calculates be equal to or less than maximum tension than time, at limit tension than in prediction unit 15, warning is sent to repair company by warning device 18, and make lift car be accommodated to nearest landing by control setup 9, notify that the passenger in this lift car leaves lift car 3 simultaneously.In addition, according to the measurement result of quality measuring apparatus in car 11, confirming that the carrying capacity of lift car 3 becomes after zero because all passengers all have left lift car 3, the door of lift car 3 is closed at once, and by operation that after this control setup is forbidden.
Consequently, the limit tension that can automatically be calculated than prediction unit 15 by limit tension becomes than and is equal to or less than maximum tension than this situation notice repair company, and after the safety suitably guaranteeing passenger, forbid that the elevator 1 that may have occurred fault runs.Therefore, it is possible to while the maintenance activity simplifying repair company, the burden of passenger is reduced to Min..
It should be noted that, in the above-described first embodiment, in order to obtain multiple different measurement result 19, in the common operation of elevator 1, under loaded state, measuring the side-play amount between main hoist cable 4 and rope sheave 6 and warp tension ratio continuously or at random.But the present invention is not limited thereto.As other embodiments, can not use the outs of service time such as the predetermined late into the night or floor time at elevator 1 yet, do not having under loaded state, automatically carry out traction of the present invention diagnosis and run.Now, by placing weight (not shown) etc. in lift car 3, making it possible to obtain multiple different measurement result 19, the precision of the warp tension ratio line of prediction 20 can be improved thus.
In addition, at usual run duration, when carrying out diagnosis operation under loaded state, because the number of each run passenger is all different with quality, so can under different carrying capacitys Observed Drift amount, but also can as other embodiments, such as when the out of service time carries out diagnosis operation, change acceleration/accel and the deceleration/decel of lift car 3, or in lift car 3, place the different not shown weight of quality, or make rope sheave 6 vibrate further, make it possible to Observed Drift amount under different warp tension ratios, obtain multiple different measurement result 19, the precision of the warp tension ratio line of prediction 20 can be improved thus.At this, in order to improve the precision of this warp tension ratio line of prediction 20, in the time of run of elevator 1, Observed Drift amount can be distinguished outward with time of run, thus can according to different carrying capacitys Observed Drift amount easily.
In addition, the warp tension ratio line of prediction 20 calculated than prediction unit 15 at limit tension can be shown on figure, also as shown in Figure 3, the many warp tension ratio line of predictions 20 can be shown.Further, when illustrating the many warp tension ratio line of predictions 20, in order to maintainer and client can confirm the diagram of this warp tension ratio line of prediction 20 easily, also can indicate on every root warp tension ratio line of prediction 20 and measuring the date 21.On this mensuration date 21, as shown in Figure 3, can illustrate and to show overlappingly near the warp tension ratio line of prediction 20 or with the warp tension ratio line of prediction 20, and also can show according to time series at a position.In addition, also can be arranged at random switch whether to show the mensuration date 21.
And, as the specification maxim 23 of the permissible value of the warp tension ratio for determining according to the specification of elevator 1 than the expression that the line of prediction 22 compares with limit tension, when also can show the manufacture of various parts according to elevator 1 larger than the actual value calculated or assembling time the value of the permissible error amount preset that determines such as permissible error.Consequently, although 25 to shorten between replacing period 24 and period of grace, can when considering that various parts manufacture or assembling time permissible error basis on to calculate between replacing period 24 and period of grace 25, so more suitably maintenance management can be carried out.In addition, by by 25 being shown as value that is more Zao than reality or the short permissible error amount preset between replacing period 24 or period of grace, also identical effect can be obtained.
Also can be configured by traction diagnostic device 12 involved in the present invention to be connected with the existing control setup 9 of elevator 1 and to make it possible to carry out traction to this elevator 1 and diagnose.In addition, also traction diagnosis can automatically be carried out by importing the maintenance routine of regulation in the elevator 1 having installed this traction diagnostic device 12 in advance in the time etc. that elevator 1 does not run.Further, also remote diagnosis or long-distance service can be carried out by being connected etc. with the communicator (not shown) of regulation.
