The utility model relates to for the equipment of tinsel (wire) rope inspection, damages definite equipment, method and program for wire strands.
background technology
Become known for checking the equipment for the defect of the wire strands of lifter and crane by magnetic leakage flux method.Checkout facility is carried into treats place that wire strands is checked.Manually with stationary fixture, checkout facility is connected to and is set in wire strands.Signal cable, power supply cable, waveform monitor etc. are also connected to the checkout facility in this place.Operator watches the waveform based on magnetic leakage flux coming across on waveform monitor and determines whether for example wire strands sustains damage.
Thereby, checkout facility is carried into for each place of each inspection of wire strands and naturally needs operator to move to this place and therefore need to pay labour cost.This also needs the long supervision time.In addition, determining whether wire strands sustains damage highly relies on operator's subjectivity.
Checkout facility for example may be fixed and for good and all be installed on lifter.But the fixing and permanent installation of checkout facility makes checkout facility (its sensor unit) and wire strands constant contact each other, wire strands and checkout facility will become wearing and tearing thus.Particularly, use as having of describing in International Patent Publication No.WO2011/148456 will make wire strands and sensor unit contact with each other via large area and accelerated wearing and tearing thus around the sensor unit of the shape of the major part of the outer surface of wire strands.Even, in the time that wire strands may be by hard magnetization and with sensor unit close contact, also can there is the acceleration of wearing and tearing.
utility model content

According to the utility model, because the sensor surface of the sensor device of the magnetic leakage flux of leaking from the wire strands being magnetized for sensing forms with plane, and in the time sensing magnetic leakage flux, sensor surface contacts with many one metal wires rope yarn, so the contact area between sensor surface and wire strands is little, and therefore sensor surface and wire strands is less may be worn.
Further, even, in the time that the wire strands of examine can have different-diameter or many one metal wires rope and can be arranged parallel to each other with different spacing, also can share the sensor device that adopts flat surface sensor surface.For example, needn't prepare different sensor devices according to the diameter of the wire strands of examine.In the time of sensor installation device, only need to place along multiple advancing (operation) wire strands the flat surface sensor surface of sensor device, this can save time and effort.
Be to be understood that, two longitudinal ends on flat surface sensor surface can be bent upwards in identical side, and in the time sensing magnetic leakage flux, two longitudinal ends of sensor surface can arrive the side of two corresponding distolateral wire strands in multiple wire strands that are arranged in parallel.This can improve the sensitivity for the damage sensing of two distolateral wire strands, and two distolateral wire strands are more possibly by major injury.

Fig. 1 shows the structure of lifter.
Lifter comprises hoistway (hoistway) 1, be arranged on machine room 2 on hoistway 1, be arranged as in hoistway 1 mobile to carry elevator car (elevator car) 3 and the wire strands 5 of passenger and goods up and down, one end of wire strands is fixed to the top (top outside) of elevator car 3, and its other end is fixed to weight equalizer (balancer weight) 4.Conventionally, multiple wire strands 5 of layout parallel to each other are for lifter.In this embodiment, use four wire strands that are arranged in parallel 5.In Fig. 1, for clear, only show one of wire strands 5.
The center section of each wire strands in four one metal wire ropes 5 is advanced (operation) through machine room 2, is wound around windlass (hoist) 6 and puts on the deflector sheave 7 being arranged in machine room 2.The lifter control panel 8 that comprises communicator 10 is arranged in machine room 2 to control windlass 6.Along with windlass 6 forwards and reverse rotation, wire strands 5 moves and correspondingly, elevator car 3 moves up and down in hoistway 1.
In machine room 2, be also provided with the rope detecting device 20 of damage for surveying wire strands 5 existence and the seriousness of crackle (break or), for the travel mechanism 30 of mobile rope detecting device 20 and for tricing line detecting device 20 and travel mechanism 30 to check the controller 9 of wire strands 5.
As mentioned above, the lifter control panel 8 being arranged in machine room 2 comprises communicator 10.Communicator 10 is connected to the surveillance 11 of lifter management company by network.The data that represent elevator conditions transfer to surveillance 11 from lifter control panel 8 via communicator 10, and monitor consistently lifter state by surveillance 11.
Lifter control panel 8 is also connected to controller 9 by signal wire.As will be described below, represent that the data of the check result (determining result) of wire strands 5 are also sent to lifter control panel 8 from controller 9 by signal wire, and then transfer to the surveillance 11 of lifter management company from lifter control panel 8.
Fig. 2 is side view, wherein, shows the travel mechanism 30 for the mobile rope detecting device 20 that is arranged on machine room 2 together with wire strands 5.
Travel mechanism 30 is fixed in machine room 2, and comprises that induction motor 31, induction motor 31 comprise the rotor (not shown) that is suitable for forward and reverse rotation in predetermined angular range.One end of the first arm 32 is fixed to the turning axle 31A of the rotor that is coupled to induction motor 31, and one end of the second arm 33 extending perpendicular to the longitudinal direction of the first arm 32 is fixed to the other end of the first arm 32.Rope detecting device connection part 34 is fixed to the other end of the second arm 33, and rope detecting device 20 is attached to rope detecting device connection part 34.In the time of driven induction motor 31, rope detecting device 20 is around turning axle 31A mobile predetermined angular on arc track.
At rope detecting device 20 while not checking wire strands 5, travel mechanism 30 detecting device 20 that makes to restrict remains on spare space.In Fig. 2, the length replacing and short dotted line instruction rope detecting device 20 remain on spare space.In the time remaining on spare space, rope detecting device 20 does not contact with wire strands 5.In the time being applied with the driving voltage of self-controller 9, induction motor 31 starts to be rotated in the forward (clockwise direction in Fig. 2).Rope detecting device 20 is close wire strands 5 gradually, and makes the flat surface sensor surface (front) of detecting device with the plane parallel being limited by multiple wire strands 5 and contact with wire strands 5, and at this, induction motor 31 stops being rotated in the forward.This position of rope detecting device 20 is called detecting location.In Fig. 2, solid line instruction rope detecting device 20 is in detecting location.The sensor surface that arrives detecting location and rope detecting device 20 at rope detecting device 20 while contacting with wire strands 5, will check wire strands 5, as will be described below.Because wire strands 5 all has the shape of cross section of sub-circular, thus sensor surface and the four one metal wire ropes 5 of rope detecting device 20 each other line contact.
In the time completing the inspection of wire strands 5, controller 9 applies inverting driving voltage to induction motor 31.So induction motor 31 starts reverse rotation (counter clockwise direction in Fig. 2) so that rope detecting device 20 returns to original spare space.
For example, controller 9 was controlled travel mechanism 30 rope detecting device 20 was moved to detecting location from spare space special time No. to three time every day, and in this timing, checked wire strands 5.Because rope detecting device 20 only just moves to detecting location in the time checking wire strands 5, so rope detecting device 20 does not contact each other with wire strands 5, can reduce thus the wearing and tearing that contact owing to the line between sensor surface and the wire strands 5 of rope detecting device 20.
Fig. 3 is the enlarged perspective of detecting device 20 of restricting in the view on the sensor surface (front) partly removed of lid 21.Fig. 4 is the viewgraph of cross-section of obtaining along the line IV-IV of Fig. 3, and Fig. 5 is the viewgraph of cross-section of obtaining along the line V-V of Fig. 3, illustrates together with wire strands 5.In Figure 4 and 5, not shown lid 21.
With reference to Fig. 3 and 5, and based on Fig. 5, rope detecting device 20 comprises: rectangular parallelepiped yoke (yoke) 22; Be fixed to a pair of cuboid magnet 24,25 of the side end on the upper surface of yoke 22; Be fixed to the upper surface of yoke 22 and with and magnet 24,25 isolated modes in this to the rectangular parallelepiped coil base 23 between magnet 24,25; And be fixed to pair of planar cell winding 26L, the 26R of the upper surface of coil base 23.With reference to Fig. 3, yoke 22, magnet 24,25, coil base 23 and coil 26L, 26R are coated with lid 21.Sensor surface (front) in order to the side of positioned coil 26L, 26R corresponding to rope detecting device 20, it forms with plane.
The length (width) of rope detecting device 20 (size on the longitudinal direction of yoke 22, magnet 24,25, coil base 23 and cell winding 26L, 26R) is greater than the whole width (, the quantity in the space between the quantity+spacing distance of diameter × wire strands 5 × adjacent wire rope 5) of four wire strands that are arranged in parallel 5.Adjust suitably the length of rope detecting device 20 according to the quantity of wire strands 5.With any speed, across the whole width of many one metal wires rope 5 of examine, rope detecting device 20(sensor surface and cell winding 26L, 26R are set).
With reference to Fig. 5, form by the magnet ring of magnet 25, wire strands 5, magnet 24 and yoke 22 from this magnetic flux that magnet 24,25 is generated, make magnetizable metal silk rope 5.Can experience the magnetized wire strands 5 of saturated magnetization or unsaturation and preferably be limited to experience unsaturation magnetization.Can adjust according to the cross-sectional area of the distance between the type of magnet 24,25, magnet 24,25 and wire strands 5, yoke 22 and/or length the magnetization degree of wire strands 5.For example, if magnet 24,25 is not neodymium, but ferrimagnet, can reduce the magnetization degree of wire strands 5.Be limited to the signal to noise ratio (S/N ratio) (S/N ratio) that unsaturation magnetization has made to improve following inspection data to be described,, and make to have reduced the wearing and tearing that contact owing between wire strands 5 and rope detecting device 20.
Referring now to Fig. 4, wire strands 5 includes eight rope strands (strand) 5B that ties up fibre core 5A and be wound around around fibre core 5A.Rope strand 5B all comprising core metal silk (core wire) (steel wire) 5a, the hermetically-sealed construction that is wound around nine internal layers tinsel (steel wire) 5b of unit of core metal silk 5a and is further wound around nine first tinsels of skin (steel wire) 5c of the tinsel 5b of internal layer unit forms (for example, be labeled as " 8 × S(19) ").Magnetic flux from magnet 24,25 passes through the excircle rope strand 5B of each wire strands 5.
In wire strands 5, rope strand 5B may be than more Zao the sustaining damage of fibre core 5A that is positioned at center, and for rope strand 5B, outer first tinsel 5c may be than core metal silk 5a and more Zao sustaining damage of the internal layer tinsel 5b of unit.While breaking, leak out wire strands 5 by the magnetic flux multilated of rope strand 5B and at the part place of breaking in the first tinsel 5c of skin.The magnetic flux that leaks out wire strands 5 will be called " magnetic leakage flux " below.In the time that the part process of breaking of magnetizable metal silk rope 5 is restricted detecting device 20, magnetic leakage flux causes electromotive force (electromotive force) on cell winding 26L, 26R.Can be according to the existence of the electromotive force on cell winding 26L, 26R and big or small existence and the seriousness of surveying the damage in wire strands 5.
Fig. 6 and 7 is the diagrams that record voltage (inspection data) that all show based on betiding the electromotive force on cell winding 26L, 26R.Vertical axes represents the magnitude of voltage based on betiding the electromotive force on cell winding 26L, 26R, has amplified 6000 times.Transverse axis represents the time in order to obtain in time from left to right magnitude of voltage.In Fig. 6 and 7, the time width (data area) corresponding with the length of a pitch (pitch) of rope strand 5B that forms wire strands 5 also indicated by solid line.
The damage that wire strands 5 is subject to is more serious (for example, the quantity of breaking of each pitch is larger), the quantity of magnetic leakage flux is larger, and correspondingly, the electromotive force occurring on cell winding 26L, 26R is higher, is about to measure higher magnitude of voltage (by the relatively discovery between Fig. 6 and 7).If the short spacing place in wire strands 5 exists the damage of multiple longitudinal separation, in the narrow data area in diagram, there are multiple voltage peak (see figure 7)s that record.
With further reference to Fig. 6 and 7, find to record consistently low voltage value.Its reason is, because wire strands 5 is wound around eight rope strand 5B formation as described above, is present on the surface of wire strands 5 so be derived from the jog of eight rope strand 5B of winding.That is, even in unmarred wire strands 5, also inevitably there is the magnetic leakage flux from the jog between eight rope strand 5B, in diagram, be revealed as the low voltage waveform that records.Manifest and be commonly referred to rope strand noise owing to this kind of waveform of the existence of the jog between rope strand 5B.Rope strand noise causes the magnitude of voltage to be measured of the peak value with about 0.3V.
Referring again to Fig. 5, in order to make to keep low as far as possible owing to the variation that records voltage (rope strand noise) of the existence of the jog between rope strand 5B, rope detecting device 20 comprises that this is to cell winding 26L, 26R, and distance " b " between two cell winding 26L and 26R (interval between the part passed through of magnetic leakage flux) is the integral multiple at the interval " a " between the top (summit) of adjacent rope strand 5B.Because leak owing to the existence of the jog between rope strand 5B and the quantity of magnetic leakage flux by two cell winding 26L, 26R has obtained on average like this, so can easily distinguish the magnetic leakage flux of leaking owing to the existence of the jog between rope strand 5B and the magnetic leakage flux of leaking owing to the damage in wire strands 5., can keep low in the variation that records the rope strand noise manifesting in voltage.
Controller 9 is exported and be supplied to the voltage (inspection data) that records that represents the waveform as shown in the diagram of Fig. 6 or 7 from rope detecting device 20.As will be described below, controller 9 use inspection data check wire strands 5.
Fig. 8 to 10 is the process flow diagrams that are illustrated in the definite algorithm of processing of wire strands damage of carrying out in controller 9.To be programmed in advance computing machine for the program of the algorithm shown in realization flow figure or be included in the storer (not shown) of controller 9.It is upper and for example, be installed in controller 9 via end device (personal computer) that program can be recorded in CD-ROM etc.End device can and pass to controller 9 by the parameter of amendment for amendment (adjustment) various parameters (for example,, for various definite multiple threshold voltages described below).
As mentioned above, for example, every day is at special time one to three time, the many one metal wires rope 5 using in controller 9 self-verifying lifters.Can will check that commencing signal is delivered to controller 9 from surveillance 11 manually or automatically, and based on checking commencing signal, can carry out inspection.First controller 9 cooperates that with lifter control panel 8 elevator car 3 is moved to attic (see figure 1), and then controls travel mechanism 30 and rope detecting device 20 is moved to detecting location (see figure 2) from spare space.Elevator car 3 at a predetermined velocity (for example 90m/min) moves to ground floor from attic, and during this period, rope detecting device 20 obtains and checks data (seeing Fig. 6 and 7).After use described below checks definite processing of data, controller 9 is controlled travel mechanism 30 detecting device 20 that makes to restrict and is returned to original spare space from detecting location.Should be appreciated that the detecting device 20 that can make to restrict returns to original spare space from detecting location at once after obtaining inspection data.
Suppose and check that data (recording voltage Vs) are not that 0V(is without waveform (waveform-less) data).If recording voltage Vs is 0V, controller 9 may or be powered still in the abnormality such as off-position and occur in the state of short circuit on the circuit board of controller 9.Travel mechanism 30 may be in abnormality, and rope detecting device 20 can not be moved to detecting location from spare space, and causing generating does not wherein have the inspection of recording voltage value data.Lifter control panel 8 for example can detect and can not obtain effective inspection data (comprise do not check data export from controller 9).In the case, lifter control panel 8 is exported and is for example transmitted and 0 is really positioned to surveillance 11.Surveillance 11 is circulated a notice of the generation of this abnormality to observer with blue alarm lamp, alarm sound etc.Alarm lamp and/or loudspeaker can be arranged on the lifter control panel 8 or controller 9 in machine room 2, and can open alarm lamp and/or send alarm sound.
From rope, detecting device 20(is shown in Fig. 6 and 7) first the inspection data (recording voltage Vs) of output be supplied to controller 9(step 41).
If record voltage at 0V<Vs<0.2V, so instead of 0V, voltage range in, the crest voltage that is not equal to or higher than 0.2V is revealed in (step 42 "Yes") in the waveform that records voltage Vs, and controller 9 is via lifter control panel 8(communicator 10) really locate and export and transfer to surveillance 11(step 43 0).As mentioned above, this is the reason that has rope strand noise in not damaged wire strands 5 even, and rope strand noise has the peak value of about 0.3V.If be not equal to or higher than the crest voltage of 0.2V, fault or open fault for example may be short-circuited on cell winding 26L, 26R.Further, in the case, really locate and transfer to surveillance 11 0, to circulate a notice of the generation of this abnormality to observer with blue alarm lamp, alarm sound etc.
Be included in (step 42 "No") in the waveform that records voltage Vs if be equal to or higher than the magnitude of voltage of 0.2V, obtain the maximum instantaneous magnitude of voltage (hereinafter referred to as crest voltage Vp) recording in waveform, and whether definite crest voltage Vp is lower than 0.6V(step 44 and 45).If crest voltage Vp lower than 0.6V, determines wire strands 5 and does not damage.In the case, controller 9 is exported 1 and is really located (step 45 and step 46 "Yes").Circulate a notice of wire strands 5 with for example green light to observer normal.
If crest voltage Vp is equal to or higher than 0.6V(step 45 "No"), magnitude of voltage is not indicated rope strand noise, but may be detected owing to the damage in wire strands 5.Controller 9 carries out as follows the two-stage of the seriousness to the damage in wire strands 5 and determines.
First determine whether crest voltage Vp is equal to or higher than 1.4V(step 47).
If crest voltage Vp is equal to or higher than 1.4V(step 47 " 1.4≤Vp "), can in wire strands 5, there is the damage of relatively high seriousness.In the case, controller 9 is exported definite carry-out bit of 3, and correspondingly, and surveillance 11 is with the notice wire strands 5 such as red alarm lamp, alarm sound sustain damage (step 51).In the time that notice wire strands 5 sustains damage, conventionally carry out detailed (minute) inspection which root for identifying many one metal wires rope 5 sustains damage.
If crest voltage Vp is equal to or higher than 0.6V still lower than 1.4V(step 47 "Yes"), the quantity (seeing Fig. 6 and 7) of the magnitude of voltage (peak value) in the scope of length (with a data area that pitch the is corresponding) inside counting 0.6V≤Vs<1.4V of a pitch of rope strand 5B next, and then quantification is one or larger (step 48 and 49).This determines whether intensively to occur a part damage of relative lower severity.
If be equal to or higher than 0.6V is still one lower than the quantity of the magnitude of voltage in the scope of 1.4V in the length of a pitch, may in of wire strands 5 part, concentrate and damage.In the case, controller 9 is exported definite carry-out bit of 2, and correspondingly uses for example yellow alarm lamp to cause observer's attention (step 49 and step 50 "Yes").
On the other hand, in the length of a pitch, be still two or larger lower than the quantity of the magnitude of voltage in the scope of 1.4V if be equal to or higher than 0.6V, damage may be relative lower severity, but can in a segment set, occur.In the case, controller 9 is exported definite carry-out bit of 3 and is circulated a notice of extremely to observer with red alarm lamp, alarm sound etc., as the situation that crest voltage Vp is equal to or higher than 1.4V (step 49 and step 51 " two or larger ").
Above-mentioned algorithm is determined rope detecting device 20(cell winding 26L, 26R with the first threshold voltage of 0.2V) whether in abnormality, determine with the Second Threshold voltage of 0.6V whether wire strands 5 sustains damage, and the two-stage of the seriousness of damaging with the 3rd threshold voltage of 1.4V is determined.Obtain this three threshold voltages by detection, below will describe its details.
Figure 11 shows and uses rope detecting device 20 to measure the result of the detection of the wire strands 5 of damage, shows the value (having amplified 6000 times) that uses the crest voltage Vp that rope detecting device 20 records.Figure 12 is the diagram of drawing based on testing result shown in Figure 11, shows crest voltage Vp(vertical axes) and defect through the relation between position (angle) (described below) (transverse axis).Figure 13 shows the position relationship between wire strands 5 and rope detecting device 20.In the form of Figure 11, some values of crest voltage Vp do not have symbol in its upper right side, and some have two symbols (* *) in its upper right side, and other have a symbol (*) in its upper right side.The value instruction with two symbols (* *) is according to will notifying abnormal generation (step 51) in definite processing (Fig. 8 to 10) of algorithm.The value instruction with a symbol (*) is according at least will arouse attention in definite processing of algorithm (step 50).Do not have the value instruction of symbol there is no abnormal determining.
In this detects, use and there is 8 above-mentioned × S(19) structure and four one metal wire ropes 5 of the diameter of 10mm, their layouts parallel to each other, have the space of 3mm between adjacent wire rope 5.After in advance all four one metal wire ropes 5 being demagnetized, try to have carried out to detect for several times.Inspection data shown in Figure 11 and 12 not in attempting for the first time (wherein wire strands 5 after by demagnetization for the first time through rope detecting device 20) obtain, but obtain in the attempting for the second time of demagnetization not.Its reason is, attempts by several, and the data of obtaining in trial for the second time and subsequently only have little departing between attempting, but the data of obtaining in attempting are for the first time significantly different from the data of obtaining in trial for the second time and subsequently.In trial for the second time and subsequently, wire strands 5 has residual magnetism, because it is magnetized in previous trial, and it is magnetized with residual magnetism and the magnetic between trial period generally.Adjust the magnetized degree (size) between trial period, make residual magnetism and the magnetic between trial period not experience generally saturated magnetization.
Wire strands 5 is all wound around as described above rope strand 5B and prepares, and rope strand 5B is all prepared by being wound around many first tinsels.Wire strands 5 may sustain damage in the tinsel 5c of skin unit in the first tinsel that forms rope strand 5B.In measurement detects, first, select the specific one metal wire rope (not comprising the wire strands at two ends) in four one metal wire ropes 5, and in a pitch of the tinsel 5c of skin unit that forms one of eight rope strand 5B of wire strands 5, deliberately manufacture the various quantity of breaking, and the four one metal wire ropes 5 that then make to comprise the wire strands with the tinsel 5c of skin unit breaking are through rope detecting device 20.
In the form of Figure 11, the quantity of breaking in a pitch of outer first tinsel 5c is shown in row " quantity of breaking ".But " strand " under shows the result of following detection: a rope strand 5B who comprises outer first tinsel 5c not only but also the internal layer tinsel 5b of unit and core metal silk 5a breaks completely.
For example, the quantity of breaking " in first tinsel one " means to select specific rope strand 5B, this specific rope strand 5B forms the specific one metal wire rope in two one metal wire ropes 5 between the wire strands at the two ends in four wire strands that are arranged in parallel 5, and in a pitch of the tinsel 5c of skin unit that forms rope strand 5B, manufactures one and break.
Referring now to Figure 13, first skin tinsel 5c can be categorized as to three types: (i) the first tinsel in summit (crown): only with in identical strand 5B in both sides first tinsel of the tinsel 5c of adjacent skin unit contact contact; (ii) the first tinsel of roll gap (nip): the first tinsel also contacting with the tinsel 5c of skin unit in adjacent rope strand 5B; And (iii) bed first tinsel: the first tinsel contacting with fibre core 5A.The summit, roll gap and the first tinsel of bed that are even included in the tinsel 5c of skin in identical rope strand 5B unit have to rope detecting device 20(sensor 26L, 26R) different distance separately.In measuring and detecting, secondly, make the quantity of not only breaking, and also the position of breaking in the first tinsel 5c of skin, difference.
With reference to Figure 11, which in the first tinsel of row " type of breaking " instruction bed, roll gap unit's tinsel and summit unit tinsel broken.The quantity of for example, breaking " in first tinsel one " shows the testing result for break " bed tinsel breaks ", " roll gap tinsel breaks " and " summit tinsel breaks " of three types.This means to occur one in a pitch of " bed ", " roll gap " or " summit " outer first tinsel 5c and breaks, and this is normal conditions.
In addition, see Fig. 1,2 and 13 because only rope detecting device 20(is set in a side of wire strands 5), so in the time having the wire strands 5 of breaking through rope detecting device 20, break the closer to rope detecting device 20, crest voltage becomes higher, and it is larger apart from the distance of rope detecting device 20 to break, crest voltage becomes lower.Therefore, in measurement detects, the 3rd, also make the angle position difference of breaking with respect to rope detecting device 20.With reference to Figure 13, different situations are detected, wherein limit the position relationship between breaking in rope detecting device 20 and wire strands 5 by the different angle positions of 0,45,90,135 and 180 degree (corresponding from above-mentioned " defect is through position (angle) "), wherein, 0 spends the most close rope detecting device 20 that means to break, and 180 degree mean to break from rope detecting device 20 farthest.
In the form of Figure 11, also in row " noise (V) ", having illustrated may be owing to the magnitude of voltage of above-mentioned rope strand noise (quiescent voltage value).
With reference to the form of Figure 11, in all testing results, the magnitude of voltage that rope strand noise causes is 0.3 to 0.4V.This is by for determining rope detecting device 20(cell winding 26L, 26R) whether be set as the reason of 0.2V in the first threshold voltage of abnormality.What rope strand noise caused record voltage is equal to or less than 0.2V hardly, and in the time only getting the crest voltage of first threshold voltage that is equal to or less than 0.2V, determine as described above rope detecting device 20(cell winding 26L, 26R) in abnormality (step 43).
With reference to the diagram of form and Figure 12 of Figure 11, for nearly all testing result, in the defect of 0 degree through position (the most close rope detecting device 20 breaks), crest voltage uprises, and for the damage of same type, approach 180 degree (breaking apart from the larger distance of rope detecting device 20), crest voltage step-down with defect through position.Sensitivity minimum 180 degree defects through position, except the quantity of breaking " rope strand ", the crest voltage that is equal to or higher than 0.6V is not shown.Through position, the whole rope strand 5B that breaks is shown to the crest voltage Vp higher than the 1.3V of the Second Threshold voltage of 0.6V in the defect of 180 degree, and therefore arouse attention (seeing step 49 and 50).
In the defect of 135 degree through position, the 3rd threshold voltage for the crest voltage Vp of the whole rope strand 5B that breaks higher than 1.4V.Therefore notify abnormal generation (seeing step 47 and 51).In the defect of 135 degree through position, situation for " first tinsel and summit tinsel break in seven ", " first tinsel and summit tinsel break in three " and " first tinsel and summit tinsel break in two " shows 0.6V or higher crest voltage Vp, and therefore arouses attention.
, also arouse attention for the situation of " first tinsel and roll gap tinsel break in four " through position in the defect of 90 degree.
In the defect of 45 degree through position, not only to break rope strand, and the situation of " first tinsel and summit tinsel break in seven " and " first tinsel and summit tinsel break in three " is shown to the crest voltage Vp higher than the 3rd threshold voltage of 1.4V, and therefore notify abnormal generation., also arouse attention for the situation of " first tinsel and summit tinsel break in ", " first tinsel and bed tinsel break in two ", " first tinsel and roll gap tinsel break in two " and " first tinsel and summit tinsel break in two " through position in the defect of 45 degree.
, do not arouse attention through position in the defect of 0 degree, but notify for the situation execute exception of " first tinsel and bed tinsel break in four " and " first tinsel and roll gap tinsel break in four ".
Although the defect at 180 degree is somewhat low through the sensitivity of position, can be by by for determining the Second Threshold voltage that whether sustains damage of wire strands 5 is set as 0.6V and the 3rd threshold voltage settings that the secondary of the seriousness for damaging is determined is that 1.4V comes relatively successfully to carry out and notes causing and abnormity notifying.
Be to be understood that, first, second and the 3rd threshold voltage are only exemplary, and can improve the sensitivity for determining whether wire strands 5 sustains damage by reducing Second Threshold voltage, and can improve by reducing the 3rd threshold voltage the quantity of the situation of execute exception notice.
Figure 14 and 15 shows and those forms shown in Figure 11 and 12 and corresponding form and the diagram of diagram, show rope detecting device 20 be not arranged on as shown in Figure 16 wire strands 5 a side but in the result of the simulation of the situation of both sides.Two rope detecting devices 20 are set allow and improve the sensitivity through position in the defect of from 90 to 180 degree to place the mode of wire strands 5 from both sides like this.With reference to Figure 14, arrange compared with the situation of a side that rope detecting device 20 makes to be only arranged on wire strands 5 with the detecting device 20 of restricting in the both sides of wire strands 5, improve the frequency of noting causing (seeing symbol *) and alert notification (seeing symbol * *).Arranging in the both sides of wire strands 5 like this rope detecting device 20, the situation that can be arranged on a side with rope detecting device 20 differently arranges second and the 3rd threshold voltage.
Figure 17 be corresponding to Fig. 4 according to the viewgraph of cross-section of the rope detecting device 20A of another embodiment.20A is different from the rope detecting device 20 shown in Fig. 4 for rope detecting device, because sensor surface (cell winding 26L, 26R; In Figure 17, only show coil 26L) two longitudinal ends be bent upwards (towards wire strands 5).The coil base 23 that supports cell winding 26L, 26R also has the part of raising being formed on its two ends.
If the whole width of four wire strands that are arranged in parallel 5 (interval between wire strands 5) be greater than in the sheave of windlass 6 and/or deflector sheave 7(see Fig. 1) in the width of groove, by the surface of the wire strands at the two ends in the four one metal wire ropes 5 that contact with sheave to extrinsic deflection, and thus with sheave close contact, sustain damage more post than two remaining wire strands 5.The sensor surface (cell winding 26L, 26R) of rope detecting device 20A thus two ends to two corresponding distolateral tinsel side bendings of four one metal wire ropes 5, this can improve the sensitivity of the damage sensing of the wire strands 5 distolateral for two.
