Specific embodiment

In the following, being described with reference to mode for carrying out the present invention.

Embodiment 1

Fig. 1 is the structure chart for showing the lift appliance of embodiments of the present invention 1.It is equipped in the figure on the top of hoistway 1 Computer room 2.Traction machine 3 is equipped in computer room 2.Traction machine 3 have driving rope sheave 4, make drive rope sheave 4 rotate traction machine motor 5 with And to the traction machine brake 6 that the rotation of driving rope sheave 4 is braked.

As traction machine brake 6, electromagnetic brake has been used.Electromagnetic brake includes brake shoe, approachs and leave The braked wheel 7 (brake drum or brake disc) rotated integrally with driving rope sheave 4；Tripping spring presses brake shoe in braked wheel 7 On；And electromagnet, overcome the active force of tripping spring that brake shoe is pulled away from braked wheel 7.

The rotation detector 8 for generating signal corresponding with the driving rotation of rope sheave 4 is equipped in traction machine 3.Rotation detector 8 Such as become device using encoder or rotation.

Deflector sheave 9 is equipped near driving rope sheave 4.Suspension body 10 is winded on driving rope sheave 4 and deflector sheave 9.As Suspension body 10 uses a plurality of rope or multi-ribbon.

1st end of suspension body 10 is connect with carriage 11.2nd end of suspension body 10 is connect with counterweight 12.Carriage 11 and Counterweight 12 is hung in hoistway 1 by means of suspension body 10, and is gone up and down in hoistway 1 by means of the driving force of traction machine 3.Driving The rotation of rope sheave 4 passes to suspension body 10 by the frictional force between driving rope sheave 4 and suspension body 10.

A pair of of the car guide rail (not shown) guided to the lifting of carriage 11 is provided in hoistway 1 and to counterweight 12 A pair of of counter weight guide track (not shown) for guiding of lifting.

Grasp the lower part that car guide rail makes the emergency braking device 13 of 11 emergent stopping of carriage be installed on carriage 11.It is hanging At the interconnecting piece with carriage 11 of body 10, equipped with the meausring apparatus 14 for generating signal corresponding with the load capacity in carriage 11.

Limiter of speed 15 is equipped on the top of hoistway 1.Limiter of speed 15 is equipped with governor sheave 16 and rope grasping device (is not schemed Show) etc..Cricoid overspeed governor 17 is winded on governor sheave 16.

Overspeed governor 17 is connect with the actuating strut of emergency braking device 13.Also, overspeed governor 17 is winded at setting In on the tensioning wheel 18 of 1 lower part of hoistway.Carriage 11 advance when, overspeed governor 17 is recycled, governor sheave 16 with The corresponding rotation speed of the travel speed of carriage 11 is rotated.

High the 2nd hypervelocity etc. of the 1st hypervelocity grade and Bi 1 hypervelocity grade higher than normal speed is set to limiter of speed 15 Grade.Limiter of speed 15 cuts off the energization to traction machine motor 5, and lead to when the travel speed of carriage 11 reaches the 1st hypervelocity grade Crossing traction machine brake 6 makes 11 emergent stopping of carriage.Also, when the travel speed of carriage 11 reaches the 2nd hypervelocity grade, speed limit Device 15 grasps overspeed governor 17 by rope grasping device, stops overspeed governor 17, acts emergency braking device 13.

Tested drafting board 19a is respectively equipped at the position corresponding with multiple stops of hoistway 1.As shown in Fig. 2, detection is tested The tested drafting board detector 19b of drafting board 19a is installed on carriage 11.The case where detection carriage 11 is located at the detection position in hoistway 1 Position sensor 19 there is tested drafting board 19a and tested drafting board detector 19b.In the embodiment 1, position sensor 19 is examined Survey the case where carriage 11 is located at landing position.But tested drafting board 19a can be located at other than landing position with detecting carriage 11 For the purpose of the case where detecting position, any position in hoistway 1 is set.

Thus elevator control gear 31 controls the operation of carriage 11 by the operating of control traction machine 3.To traction machine motor 5 energization and the energization of traction machine brake 6 is controlled by elevator control gear 31.Elevator control gear 31 stops in carriage 11 By when make traction machine brake 6 act, keep carriage 11 stationary state.

Elevator control gear 31 and the slipping state judgement dress for determining the slipping state between driving rope sheave 4 and suspension body 10 Set 22 connections.Slipping state decision maker 22 is connect with slip detector 21.

Slip detector 21 is according to the signal from rotation detector 8 and the signal from position sensor 19, detection Drive the amount of slip between rope sheave 4 and suspension body 10.

In particular, slip detector 21 is obtained according to the rotation amount of the driving rope sheave 4 detected by rotation detector 8 The sendout of suspension body 10 when not skidding.Also, slip detector 21 is according to the sendout of suspension body 10 and from quilt The signal (signal at the time of generation at position of the carriage 11 by tested drafting board 19a) of detection plate detector 19b, detects carriage 11 during the floor gap in hoistway 1 passes through in suspension body 10 sendout and pre-save floor gap distance between Departure, amount of slip when advancing as floor gap.

Slipping state decision maker 22 according to detected by slip detector 21 amount of slip information, traction machine motor 5 Driving force information and the rotation information from rotation detector 8, distinguish driving rope sheave 4 and suspension body 10 between generate it is complete Office's property is skidded and locality is skidded.

In particular, slipping state decision maker 22 detects the presence of following characteristic: that is, being detected by rotation detector 8 In the increased situation of a side in speed out and the driving force detected by traction machine motor 5, another party is reduced.Also, it beats Sliding state determining apparatus 22 is according to floor gap amount of slip and whether there is or not above-mentioned characteristics, to determine being due to driving rope sheave 4 and suspension body It the decline of driving power between 10 and the skidding locally generated and is globally generated under normal traction state Which side in small skidding.

Also, the information of the judgement result in relation to slipping state is sent to elevator controlling and filled by slipping state decision maker 22 Set 31.Elevator control gear 31 saves the information received from slipping state decision maker 22, and is used for lift appliance In control.That is, elevator control gear 31 makes sedan-chair in the case where being judged to skidding is exception caused by decline of driving power etc. The operating in compartment 11 stops.

For example, elevator control gear 31 in the case where amount of slip reaches 1 setting value, is judged to having occurred biggish beat It is sliding, make 11 emergent stopping of carriage.Even in addition, in the case that amount of slip is not up to the 1st setting value, but being set reaching than the 1st The 2nd low setting value of definite value and have occurred locality skid in the case where, be also determined as driving power decline, make carriage 11 to most Nearly floor or designated floor are mobile, and stop the operating of carriage 11.

In addition, elevator control gear 31, slip detector 21 and slipping state decision maker 22, which pass through, to be had each other solely Vertical microcomputer realizes mutually impregnable independent calculation process.

Here, the skidding detection processing carried out by slip detector 21 is described in detail.Firstly, being detected skidding Need to possess the configuration space information of tested drafting board 19a in processing.

Fig. 3 shows the process of the processing of the configuration space information for saving tested drafting board 19a.In this process, first Carriage 11 is set to be moved to benchmark floor (usually lowest level) (step 1).Then, start carriage 11 until destination floor Movement (step 2) until (usually top layer).The signal from rotation detector 8 is added up in the movement, often Aggregate-value is just saved as floor gap range information when through tested drafting board 19a, and carries out the processing (step of resetting aggregate-value 3).Finally, complete until destination floor until it is mobile when end processing.

The process flow preferably carries out after lift appliance is just installed.That is, drawing shape after lift appliance is just installed State be it is sound, do not generate skidding, it is thus possible to will drive rope sheave 4 rotation amount (driving rope sheave 4 periphery rotation caused by Advance amount) it is regarded as the sendout of suspension body 10, it is capable of the floor gap aggregate-value of the signal of spinning in future detector 8 as floor Between distance handled.

In addition, what is illustrated below is judged as YES the feelings for the state that do not skid extremely by slipping state decision maker 22 Under condition, update also can be implemented and protect stored processing.

In the following, skidding detection processing is described in detail using Fig. 4.In this process, as Fig. 3, make sedan-chair first Compartment 11 is moved to benchmark floor (usually lowest level) (step 4).Then, start carriage 11 until destination floor (usually Top layer) until movement (step 5).The signal from rotation detector 8 is added up in the movement, whenever passing through The rotation amount of the driving rope sheave 4 when aggregate-value passes through as floor gap is just saved when tested drafting board 19a, and carries out resetting aggregate-value Processing (step 6-1,2).

Also, using the difference of the rotation amount of the driving rope sheave 4 saved and floor gap range information as amount of slip export to Slipping state decision maker 22 (step 6-3).Finally, complete until destination floor until it is mobile when end processing.

In the following, being illustrated to the determination processing of skidding state determining apparatus 22, Fig. 5~7 are illustrated to be determined as skidding Object multiple slipping states.The time of the amount of slip between driving rope sheave 4 and suspension body 10 is all shown in the drawings Property variation.

Fig. 5 shows the lesser skidding globally generated in normal state, although how much size is due to carriage 11 Carrying state etc. and change, but biggish skidding will not be generated in local time.On the other hand, Fig. 6 is shown in office The larger skidding of the locality generated under portion's abnormality, the skidding development when by become duration as shown in Figure 7 compared with It is big to skid.

Here, when the relationship between the amount of slip detected to slip detector 21 is illustrated in figure will beat Dash area in sliding figure be accumulated by according to the time, each is equivalent to the amount of slip detected.According to these attached drawings may be used Know, in the case where generating the larger skidding of duration, amount of slip differs widely with other two, is easy to distinguish.But To globally generating the case where lesser skidding in normal state and locally generated under local anomaly state larger Skidding in the case where, there is no the difference of amount of slip (or smaller), both cannot distinguish between according only to amount of slip.

In contrast, Fig. 8 is the rotation for showing the driving rope sheave 4 when producing smaller skidding of overall importance shown in fig. 5 The curve graph of the Temporal changes of the driving force of rotary speed and traction machine motor 5, Fig. 9 are to show producing office shown in fig. 6 The curve of the Temporal changes of the driving force of the rotation speed and traction machine motor 5 of driving rope sheave 4 when the larger skidding of portion's property Figure.

Pass through the transition information of the driving force of the rotation speed and traction machine motor 5 using this driving rope sheave 4, Neng Goujin The differentiation of the above-mentioned two states of row.In particular, in the case where producing the skidding of locality, as shown in figure 9, generating While driving the rotation speed of rope sheave 4 to improve the phenomenon that the driving force decline of traction machine motor 5.

This is because following situation and generate: the frictional force when generating skidding between suspension body 10 and driving rope sheave 4 Decline, by the driving force applied before frictional force will decline, rotation speed is improved, and in common elevator, is utilized Elevator control gear 31 is implemented to follow the control of command speed, thus by making speed reduce drive without departing from the control of instruction value Power.

Therefore, the value that rotation speed is multiplied with driving force is focused on.Figure 10 is the rotation speed × driving for showing Fig. 8 The curve graph of the Temporal changes of the value of power, Figure 11 are the Temporal changes for showing rotation speed × driving force value of Fig. 9 Curve graph.As shown in Figure 10, in the case where producing smaller skidding of overall importance, rotation speed × driving force value is normal When mobility scale in constant.In contrast, as shown in figure 11, in the case where producing the larger skidding of locality, Rotation speed × driving force value declines at the time of generating locality and skidding, mobility scale when deviating from normal.

In this way, showing substantially to deviate not generating the usual of locality skidding by the way that rotation speed is multiplied with driving force The value of the mobility scale of traveling.Also, by capturing the feature, it can more reliably distinguish and detect exception.That is, logical The mobility scale for presetting amount that rotation speed is multiplied with driving force when normal is crossed, is detected when floor gap is advanced The case where mobility scale when the product of rotation speed and driving force is more than normal, high-precision and can simply detect locality The generation of skidding.

Alternatively, it is also possible to not implement the operation that rotation speed is multiplied with driving force, and pass through individually judgement rotation respectively Speed and driving force, to detect the generation of locality skidding.

In particular, as shown in figure 12, setting allow minimum with the common driving force when floor gap is advanced first Deviation a1 and maximum deviation b1 is allowed with the rotation speed of usual traveling mode.Then, it is lower than in the deviation of driving force and allows The deviation of the phenomenon that minimum deflection a1 and rotation speed is more than judgement the phenomenon that allowing maximum deviation b1 in simultaneous situation It skids for locality has occurred.

In addition, as shown in figure 13, it also can be inclined according to the minimum of the usual driving force with carriage 11 when floor gap is advanced Poor a2, set the rotation speed variation that can be allowed allows maximum deviation b2, is more than in the maximum value of rotation speed variation In the case where allowing maximum deviation b2, it is judged as and produces locality skidding.

Here, the setting method as b2, if so that have b2 with a2 reduces and increase and b2 as a2 increases and The mode of reduced relationship is set, then in the feelings for rising smaller but driving force and declining since locality is skidded of rotation amount Under condition and in the case that the decline of driving force is smaller but rotation amount rises since locality is skidded, can accurately it examine The locality measured in various situations is skidded.

For example, in the relationship for making that there is a2 and b2 to be inversely proportional, can according to multiplying according to rotation speed and driving force Product benchmark same when being judged is judged.As specific judgment mode, in Figure 12, the maximum deviation of rotation speed More than benchmark b2, thus it can be judged as produce locality skidding herein.

Alternatively, it is also possible to this on the contrary, first determine speed maximum deviation, driving force is determined according to the maximum deviation Allow minimum deflection, whether be more than these feasible values according to speed, to carry out generating the judgement of locality skidding.

In the following, Figure 14 shows the process of the specific slipping state determination processing of slipping state decision maker 22.Here, To destination floor mobile beginning when, into slipping state determination processing.In slipping state determination processing, receives and come from The information of the amount of slip of sliding detection device 21 carries out the 1st datum quantity of the amount of slip received and preset amount of slip Compare (step 7-1,7-2).

In the case where amount of slip is greater than 1 datum quantity, exports the 1st abnormality and (walked back to waiting processing state Rapid 7-3).On the other hand, in the case where amount of slip is less than 1 datum quantity, into the amount of slip received with it is preset The comparison of the 2nd datum quantity (the 1st datum quantity > the 2nd datum quantity) of amount of slip handles (step 7-4).

In the case where amount of slip is greater than 2 datum quantity, also implementation slip properties have evaluation (step 7-5) without exception. Specific evaluation method is as described above.

Be determined as slip properties deposit in an exceptional case, output the 2nd abnormality simultaneously return to waiting processing state (step 7-6).On the other hand, in the case where being determined as that amount of slip is less than datum quantity in step 7-4 and in step 7-5 In be judged as that slip properties do not have exception in the case where, be directly entered waiting processing state.

Here, the meaning of the 1st abnormality and the 2nd abnormality is according to the 1st and the 2nd datum quantity as decision threshold It sets and changes.For example, the 1st datum quantity be set as be service when cannot safely carry out each floor stop traction state under produce Raw amount of slip.Then, in the case where amount of slip is greater than 1 datum quantity, elevator control gear 31 rests in carriage 11 most Nearly floor stops service immediately, therefore ensures that safety.

In addition, the 2nd datum quantity is set as being the amount of slip changed according to the variation of load capacity etc. in normal state Maximum value.Then, in the case where amount of slip is the 1st datum quantity or less and is greater than 2 datum quantity, the state of lift appliance is believed Breath is transmitted to outside.Thereby, it is possible to consider to involve the utilization of the condition improvement of early stage.

As the specific transfer device of transmitting status information, such as it is contemplated that using sound to carrying out inside and outside carriage 11 Broadcast, the display that is carried out in carriage 11 using image or lamp etc. and the portable phone to user electronic communication.

Alternatively, it is also possible to by elevator control gear and maintenance activity person or the communication unit between repair company or Locality is skidded and increased is communicated by information by portable phone etc..In this case, by becoming and must stop It is safeguarded before the state of lift appliance operating, lift appliance continuous running can be made, user will not be brought in operating It is inconvenient caused by only.

Embodiment 2

Illustrate embodiments of the present invention 2 below.In embodiment 2, pass through the slipping state judgement in embodiment 1 The slip properties of device 22, which determine quantitatively to calculate in (the processing step 7-5 of Figure 14), to skid, the higher skidding of Lai Shixian precision Judgement.

The slipping state decision maker 22 of embodiment 2 according to the amount of slip information detected by slip detector 21, The driving force information of traction machine motor 5, drives rope sheave 4 and is driven in conjunction therewith the rotation information from rotation detector 8 The information of the inertia mass of the information of the inertia mass of dynamic equipment, suspension body 10 and the equipment acted in conjunction therewith, With the information for the uneven weight for acting on driving rope sheave 4, differentiation generates of overall importance between driving rope sheave 4 and suspension body 10 It skids and locality is skidded.Other structures and movement are identical as embodiment 1.

Formula 1 is equation of motion when lift appliance is driven by the frictional force between driving rope sheave 4 and suspension body 10 Formula.

[numerical expression 1]

In formula 1, J indicates the inertia mass of driving rope sheave 4 and the equipment driven in conjunction therewith, except driving rope sheave It further include the inertia mass of rotor of traction machine motor 5 etc. other than 4.J ' indicates suspension body 10 and is acted in conjunction therewith The inertia mass of equipment further include deflector sheave 9 in addition to suspension body 10, carriage 11 and counterweight 12 and hung by carriage 11 The inertia mass of cable (power cable and counterweight rope etc.) etc..

T indicates the driving force that traction machine motor 5 exports.F indicates the friction acted between driving rope sheave 4 and suspension body 10 Power.L expression acts on the uneven weight of driving rope sheave 4, refers to of the suspension body 10 of 11 side of carriage when carriage 11 is stopped The power of the difference of the tension of the suspension body 10 of 12 side of power and counterweight.

Here, in addition to the load capacity in the weight of carriage 11 and carriage 11, from driving rope sheave 4 to the suspension of carriage 11 The weight of body 10 and the weight for the cable hung by carriage 11 also influence the tension of the suspension body 10 of 11 side of carriage.Together Sample, in addition to the weight of counterweight 12, from driving rope sheave 4 to the weight of the suspension body 10 of counterweight 12 and the line hung by counterweight 12 The weight of cable class also influences the tension of the suspension body 10 of 12 side of counterweight.

W indicates the rotation speed of driving rope sheave 4, and V indicates the submitting speed of suspension body 10.In addition, the mark table with point on W Show that the time diffusion of W, the upper mark with point of V indicate the time diffusion of V.

Then, it is obtained when with ratio δ (skidding rate) Lai Dingyi slip speed of the rotation speed relative to driving rope sheave 4 Formula 2.

[numerical expression 2]

Numerical expression transformation is carried out to formula 1 as a result, obtains relational expression shown in formula 3.

[numerical expression 3]

The formula 3 by inertia mass J and J ', drive rope sheave 4 rotation speed W, the driving force T of traction machine motor 5, imbalance Weight L, skidding rate δ relationship be classified as differential equation and show.Also, in the slip detector of embodiment 2 21, according to Formula 3 calculates skidding rate.

In the calculating of the skidding rate, it is thus necessary to determine that each value in formula other than δ.In each value, J and J ' are inertia matter Amount, it is thus possible to be calculated according to system structure.In addition, W is the rotation speed for driving rope sheave 4, it is thus possible to according to coming from The signal of rotation detector 8 is calculated.In addition, T indicates the driving force that traction machine motor 5 exports, it is thus possible to traction machine The driving current of motor 5 is converted and is calculated.
