The specific embodiment
Below, illustrate referring to the drawings for implementing mode of the present invention.
Embodiment 1
Fig. 1 means the constructional drawing of the lift appliance of embodiments of the present invention 1.In the drawings, car 1 and counterweight 2 are suspended in hoistway by the many main ropes 3 as suspension body, by propulsive effort lifting in hoistway of towing machine 4.Suspension body can adopt many load-transfer devices.Be provided with a plurality of guide rails (not shown) of the lifting of guiding car 1 and counterweight 2 in hoistway.
And, be provided with the deflector wheel 8 that is wound with main rope 3 near driving rope sheave 5.In addition, the fixed part in hoistway is provided with emergency braking device 9 near deflector wheel 8, by controlling 3 pairs of cars 1 of main rope, is braked.
At motor 6, be provided with as the motor encoder 11 that drives rope sheave side detecting unit (the 1st detecting unit), it produces with the rotation of the S. A. of motor 6, drives signal corresponding to the rotation of rope sheave 5.In addition, as long as drive rope sheave side detecting unit can detect the rotation amount that drives rope sheave 5, such as adopting magslip or tachogenerator etc.
The running of towing machine 4 is controlled by control device for running the engine 12.Control device for running the engine 12 makes car 1 operation, stops according to call.And control device for running the engine 12 converts according to the output from motor encoder 11 signal that speed obtains to, to power inverter 13, relay 14 and traction machine brake 7, provides command signal.
At governor belt pulley 20, be provided with as the governor coder 23 that hangs side detecting unit (the 2nd detecting unit), it produces the signal (that is, with the movement of car 1 and main rope 3 corresponding signal) corresponding with the rotation of governor belt pulley 20.In addition, as long as hang the position (amount of movement) that the side detecting unit can detect car 1 or main rope 3, such as adopting magslip or tachogenerator etc.
The output signal of motor encoder 11 and governor coder 23 is imported into state monitoring apparatus 30.State monitoring apparatus 30, according to the output signal of motor encoder 11 and governor coder 23, monitors that tractive force descends.That is, state monitoring apparatus 30 is to monitor according to main rope 3 and the position deviation that drives rope sheave 5 circuit that tractive force descends.
Fig. 2 means the block diagram of structure of the state monitoring apparatus 30 of Fig. 1.The output of governor coder 23 is converted into position signal D1 by position transducer 31.The output of motor encoder 11 is converted into position signal D2 by position transducer 31.
The position signal D1 Negotiation speed conv 32 of governor coder 23 is converted into speed signal V1.Speed signal V1 is converted into speed signal V2 by low-pass filter 33.The characteristic oscillation number that the cutoff frequency of low-pass filter has according to elevator device changes, normally several hertz.
Fig. 3 means the diagram of circuit of action of the detection unit 34 of Fig. 2.If near zero and more than than zero large threshold speed Vstart, detection unit 34 starts supervision (step 1) from the speed signal V1 of the car 1 of governor coder 23.After starting supervision, detection unit 34 is stored (step 2) to the position signal D2 from motor encoder 11 as initial value D0.
The monitor program of detection unit 34 comprises following three steps.; at first will from the position deviation of the location information D1 of the car 1 of governor coder 23 and the location information D2 of driving rope sheave 5 from motor encoder 11 (| D1-D2|); with an amount of movement (Δ D2=|D2-D0|) of driving rope sheave 5, the curve F3 as the threshold value of benchmark compares; if position deviation is larger than F3; be judged to be extremely output signal output L3(step 3).
Then, by position deviation (| D1-D2|) compare with curve F2, if position deviation is larger than F2, be judged to be abnormal, output signal output L2(step 4).Finally, by position deviation (| D1-D2|) compare with curve F1, if position deviation is larger than F1, be judged to be abnormal, output signal output L1(step 5).
Decline grade as curve F1, the F2 of the threshold value of the determinating reference of position deviation, F3 corresponding to tractive force, F3 > F2 > F1.And detection unit 34 compares the curve of position deviation and threshold value, in the situation that surpass threshold value, be judged to be extremely, according to surpassing grade output signal output L1, L2, L3.
In the situation that judgement is the common operation of lift appliance be there is no to the process observation grade of obstruction, to control device for running the engine 12 output signal output L1.Control device for running the engine 12 records receive the situation of output signal L1, but to towing machine 4 and emergency braking device 9, do not give an order.And service personnel is confirmed the reception historic records of the output signal L1 in control device for running the engine 12 when periodic inspection, if received, thickly carry out the maintenance of main rope 3 and driving rope sheave 5 week.
In the situation that being flat bed deviation etc., judgement likely common operation is produced to the service stopping grade hindered, to control device for running the engine 12 output signal output L2.When control device for running the engine 12 receives output signal L2, control power inverter 13 and make car 1 rest in nearest floor.Now stop that deceleration/decel can to stop deceleration/decel little than common.Then, relay 14 is disconnected, cut off the electric power of motor 6 is supplied with, interrupt the generation of motor torque, and make traction machine brake 7 actions, make elevator under the passenger.And, by telephone line etc., require service personnel to go to work, stop the service of lift appliance.
In the situation that judgement is the emergent stopping grade that need to stop at once, to emergency braking device 9 output signal output L3.Emergency braking device 9 is when power supply is cut off, and controls the brake equipment of the fail safe type that 3 pairs of cars 1 of main rope are braked, and according to output signal L3, cuts off the electric power of emergency braking device 9 is supplied with.
After above-mentioned monitor program finishes, the speed signal V2 of car 1 and threshold speed Vend are compared (step 6), if V2 > Vend, return to step 3, repeatedly carry out monitor program.And, if V2<=Vend finishes to monitor, and returns to step 1.
In said procedure, speed signal V1 is the speed signal of the car 1 do not processed by filtering, thereby the action that can capture rapidly car 1 in step 1 starts and start to monitor.And, even in the situation that drive the rotation of rope sheave 5 to stop, just in case car 1 is because skidding of main rope 3 starts to move, the supervision that can will begin in a minute.
On the other hand, the end of supervision need to be carried out on the basis that car 1 has stopped confirming reliably.But by hanging as elastomeric main rope 3, thereby the speed of car 1 is difficult to judge in this state stopping of car 1 in vibration due to car 1.Therefore, the judgement speed speed signal V2 that speed signal V1 is implemented to low-pass filtering treatment and obtain finished as supervision.Now, the speed signal V2 after low-pass filtering treatment is also in slow vibration, thus can think speed signal V2 after car 1 stops lower than zero.Therefore, threshold value Vend can be set as zero.
If the algorithm that adopts this supervision to start, stop, comparing with the situation that monitors merely all the time the deviation of position (be offset in this case and accumulated), be reset whenever stopping hour offset, thereby can realize monitoring more accurately.And, due to using car 1 car from start to stopping 1 with the position signal deviation that drives rope sheave 5 as monitored object, thereby can not limit monitoring range.
Fig. 4 means the diagram of curves by the 1st example of curve F1, the F2 of the threshold value of the position deviation of detection unit 34 uses of Fig. 2, F3.F1, F2, F3 in the 1st example utilizes following formula to be expressed as follows (formula (1)～formula (3)).
F1＝α*ΔD2＋δ1......（1）
F2＝α*ΔD2＋δ2......（2）
F3＝α*ΔD2＋δ3......（3）
Wherein, using elevator device with respect to the maxim of the rate of creeping of the amount of movement that drives rope sheave 5 (the driving rope sheave 5 produced under travel condition usually and the sliding ratio of main rope 3) as benchmark, factor alpha is set for large to not carrying out the degree of misoperation.For example, the maxim of the rate of the creeping when maxim of the displacement vibration amplitude of the car 1 produced when set strength that the passenger is usingd in car 1 is shaken car 1 is accelerated as benchmark or car, as benchmark, is set δ 1 for large to not carrying out the degree of misoperation.Further consider and prevent that the surplus that misoperation is used from setting δ 2, δ 3 for δ 1, make δ 1<δ 2<δ 3.
Fig. 5 means the diagram of curves by the 2nd example of curve F1, the F2 of the threshold value of the position deviation of detection unit 34 uses of Fig. 2, F3.F1, F2, F3 in the 2nd example utilizes following formula to be expressed as follows (formula (4)～formula (6)).
F1＝α1*ΔD2＋δ......（4）
F2＝α2*ΔD2＋δ......（5）
F3＝α3*ΔD2＋δ......（6）
Wherein, factor alpha 1 is identical with the α of formula (1).Consider that for α 1 surplus that can not carry out the degree of misoperation sets α 2, α 3, make α 1<α 2<α 3.δ is identical with the δ 1 of formula (1).
Like this, owing to being suitable for the curve that threshold value changes according to the amount of movement Δ D2 that drives rope sheave 5, thereby monitor that precision improves.And, due to the amount of movement Δ D2 driving rope sheave 5, as benchmark, thereby be not easy to be subject to the impact of the vibration of car 1 or main rope 3.
In addition, slope situation (Fig. 4) and the displacement vibration amplitude fixing situation (Fig. 5) fixing with respect to Δ D2 of F1, F2, F3 has been shown in embodiment 1, but curve F1, the F2 of threshold value, F3 are not limited to these situations, as long as change according to the amount of movement Δ D2 that drives rope sheave 5, just can bring into play identical effect.
And, when surpassing the curve of the higher threshold value such as this hazard level of F3, emergency braking device 9 is moved, thereby must avoid misoperation.Therefore, also threshold curve can be set as highlyer than F1, F2, and be the fixed value irrelevant with the amount of movement Δ D2 that drives rope sheave 5.
In addition, in embodiment 1, be the curve setting of threshold value three phases, but stage quantity is not limited to three.
Below, Fig. 6 means the constructional drawing of the lift appliance of embodiments of the present invention 2.In the drawings, at traction machine brake 7, be provided with the brake switch 45 as braking detecting unit (the 3rd detecting unit), for detection of the action of traction machine brake 7/non-action.Brake switch 45 is to judge the switch of the action of traction machine brake 7/non-action according to the movement of the movable part in traction machine brake 7.And brake switch 45 is exported the ON signal when traction machine brake 7 is operating state (braking mode), output OFF signal when being non-action status (disarm state).
The output signal of motor encoder 11 and brake switch 45 is imported into state monitoring apparatus 40.State monitoring apparatus 40, according to the output signal of motor encoder 11 and brake switch 45, monitors the decline of the braking potential of traction machine brake 7.That is, state monitoring apparatus 40 is to monitor the circuit of decline of the braking potential of traction machine brake 7 according to the speedup degree that drives rope sheave 5.
Fig. 7 means the block diagram of structure of the state monitoring apparatus 40 of Fig. 6.The output of motor encoder 11 is converted into speed signal V11 by position transducer 41 and velocity transducer 42.Detection unit 44, according to the output signal S1 of speed signal V11 and brake switch 45, monitors the state of lift appliance.
And, detection unit 44 when being judged to be lift appliance and having produced error state, according to the grade of this error state, output signal L11, L12, the L13 of output for tackling error state.The function of detection unit 44 for example can utilize micro computer or analog logic circuit to realize.Other structure is identical with embodiment 1.
Fig. 8 means the diagram of circuit of action of the detection unit 44 of Fig. 7.If the output signal S1 of brake switch 45 is ON, detection unit 44 starts to monitor (step 11).After starting supervision, detection unit 44 is stored (step 12) to the speed signal V11 of the driving rope sheave 5 from motor encoder 11 as rate of onset V0.
The monitor program of detection unit 44 comprises following three steps.; at first will be from the speed signal V11 of the driving rope sheave 5 of motor encoder 11 the speedup amount (Δ V11=|V11|-|V0|) with respect to rate of onset V0; with threshold speed δ 13, compare; if V11 is larger than threshold value δ 13 for speedup amount Δ; be judged to be extremely output signal output L13(step 13).
Then, speedup amount Δ V11 and threshold speed δ 12 are compared, if speedup amount Δ V11 is larger than threshold value δ 12, be judged to be extremely output signal output L12(step 14).Finally, speedup amount Δ V11 and threshold speed δ 11 are compared, if the speedup amount is larger than threshold value δ 11, be judged to be extremely output signal output L11(step 15).
After above-mentioned monitor program finishes, confirm the output signal S1(step 16 of brake switch 45), if ON returns to step 13 and repeatedly carries out monitor program.And, if output signal S1 is OFF, finish to monitor and return step 11.
Consider the action delay, decision delay of traction machine brake 7 etc., the maximum speedup degree of the elevator device during using traction machine brake 7 regular event, as benchmark, is set threshold speed δ 11 for large to not carrying out the degree of misoperation.Further consider and prevent that the surplus that misoperation is used from setting δ 12, δ 13 for δ 11, make δ 11<δ 12<δ 13.
That is,, as threshold speed δ 11, δ 12, the δ 13 of the determinating reference of speedup amount, corresponding to the decline grade of braking potential, δ 13 > δ 12 > δ 11.And detection unit 44 will drive speedup degree and the threshold speed of rope sheave 5 to compare, in the situation that surpass threshold value, be judged to be extremely, according to surpassing grade output signal output L11, L12, L13.
In the situation that judgement is the common operation of lift appliance be there is no to the process observation grade of obstruction, to control device for running the engine 12 output signal output L11.Control device for running the engine 12 records receive the situation of output signal L11, but to towing machine 4 and emergency braking device 9, do not give an order.And service personnel is confirmed the reception historic records of the output signal L11 in control device for running the engine 12 when periodic inspection, if received, week is thickly carried out the maintenance of traction machine brake 7.
In the situation that judgement is likely common operation to be produced to the service stopping grade hindered, to control device for running the engine 12 output signal output L12.When control device for running the engine 12 receives output signal L12, control power inverter 13 and make car 1 rest in nearest floor.Then, relay 14 is disconnected, cut off the electric power of motor 6 is supplied with, interrupt the generation of motor torque, and, make traction machine brake 7 or emergency braking device 9 actions, make elevator under the passenger.And, by telephone line etc., require service personnel to go to work, stop the service of lift appliance.
In the situation that judgement is the emergent stopping grade that need to stop at once, to emergency braking device 9 output signal output L13.Emergency braking device 9 is when power supply is cut off, and controls the brake equipment of the fail safe type that 3 pairs of cars 1 of main rope are braked, and according to output signal L3, cuts off the electric power of emergency braking device 9 is supplied with.
State monitoring method according to above-mentioned lift appliance, the speedup amount of the driving rope sheave 5 that traction machine brake 7 is started to have moved is as the supervision project, and compare with threshold speed, thereby compared the impact that is not easy to be vibrated by the position of the car 1 hung as elastomeric main rope 3 and the situation of speed with supervision.And, not only can when stopping, car 1 be monitored, also can when advancing, car 1 be monitored.
In addition, in embodiment 2, threshold speed is set as to three phases, but stage quantity is not limited to three.
And, in embodiment 2, signal S1 is the brake switch output signal of traction machine brake 7, but, so long as the electric current change while making traction machine brake 7 action and variation in voltage etc. can be judged the signal of the action of traction machine brake 7/non-action, also can utilize other signal.For example, in the situation that standby current change, the energising of cut-out to restraining coil when carrying out braking maneuver, thereby the electric current slow decreasing of drg, but brake shoe is actual start action after, electric current is temporary transient increasing due to speed electromotive force.Therefore, by catching curent change, can confirm braking maneuver.The situation that monitors variation in voltage is also identical.
Below, Fig. 9 means the constructional drawing of the lift appliance of embodiments of the present invention 3.In the drawings, the top in hoistway is provided with upper position display panel (upper marker) 56.Upper position display panel 56 is fixed on the level position of top layer usually.Bottom in hoistway is provided with lower position display panel (bottom mark) 57.Lower position display panel 57 is fixed on the level position of the bottom usually.
In addition, position transduser 55 and position display plate the 56, the 57th, arrange in the conventional lift device for the level position (door zone) that detects each floor, do not need to reset.
The output signal of position transduser 55 is imported into control device for running the engine 12.Control device for running the engine 12 is confirmed the load condition in car call and car 1 every the fixed cycle.In the situation that confirm not have car call and the interior nobody of car 1, control device for running the engine 12 makes car 1 move to the position of position sensor 55 identification lower position display panels 57, outgoing inspection mode signal C1, and, operation mode is switched to checking mode from normal mode.
When checking mode, control device for running the engine 12 makes car 1 temporarily move to the position of position sensor 55 identification upper position display panels 56, then makes car 1 move to the position of position sensor 55 identification lower position display panels 57.Like this, after advancing between predefined test zone finished, control device for running the engine 12 stops car 1, and, checking mode signal C1 is stopped.That is, checking mode signal C1 is OFF usually the time, in checking mode the time, at car 1, travels to and fro between lower position display panel 57 in during between upper position display panel 56, and checking mode signal C1 is ON.
Checking mode signal C1 from control device for running the engine 12 is imported into state monitoring apparatus 50.State monitoring apparatus 50, according to the output signal of checking mode signal C1 and motor encoder 11, monitors that tractive force descends.Other structure is identical with embodiment 1.
Figure 10 means the block diagram of structure of the state monitoring apparatus 50 of Fig. 9.State monitoring apparatus 50 during acceptace inspection mode signal C1, the output signal of monitoring motor coder 11.The output of motor encoder 11 is converted into position signal D1 by position transducer 51, and the position deviation that car 1 was moved and again turned back to lower position display panel 57 from lower position display panel 57 is accumulated.
The position signal D12 of the position signal D11 of the lower position display panel 57 after detection unit 54 has just started checking mode, the lower position display panel 57 with checking mode after just having finished compares, in the situation that its difference surpasses predetermined threshold value, is judged to be extremely.And detection unit 54 is according to abnormal grade, output is used for signal L21, the L22, the L23 that tackle error state.The function of detection unit 54 for example can utilize micro computer or analog logic circuit to realize.
Figure 11 means the diagram of circuit of action of the detection unit 54 of Figure 10.If the checking mode signal C1 from control device for running the engine 12 is ON, position signal D11(step 21, step 22 that detection unit 54 is stored these states).Then, the round running of the car 1 in checking mode finishes, if are OFF from the checking mode signal C1 of control device for running the engine 12, and position signal D12(step 23, step 24 that detection unit 54 is stored these states).
The judgement of checking mode is undertaken by following three steps.; the differential position (Δ D1=|D11-D12|) of the position signal D12 of the rope sheave of the driving from motor encoder 11 after the position signal D11 of the rope sheave of the driving from motor encoder 11 after at first checking mode just having been started and checking mode have just finished; with predefined threshold value TH3, compare; if D1 is larger than threshold value TH3 for the differential position Δ; be judged to be extremely output signal output L23(step 25).
Then, differential position Δ D1 and threshold value TH2 are compared, if differential position Δ D1 is larger than threshold value TH2, be judged to be extremely output signal output L22(step 26).Finally, differential position Δ D1 and threshold value TH1 are compared, if differential position Δ D1 is larger than threshold value TH1, be judged to be extremely output signal output L21(step 27).
In the situation that any step all is not judged to be is abnormal, detection unit 54 does not return to step 21 to control device for running the engine 12 output signals, and lift appliance is in common running.
When car 1 comes and goes set lifting travel from certain starting position of advancing under no load condition, turn back to again in the situation of advancing starting position and stopping, the maxim of the positional error after having considered common the creeping of likely occurring of towing machine rotating speed, as benchmark, is set threshold value TH1 for large to not carrying out the degree of misoperation.Further consider and prevent that the surplus that misoperation is used from coming setting threshold TH2 and threshold value TH3 for TH1, make TH1<TH2<TH3.
That is, threshold value TH1, TH2, TH3 are corresponding to the decline grade of tractive force, TH3 > TH2 > TH1.And detection unit 54 will drive the departure of rope sheave 5 and threshold value to compare, in the situation that surpass threshold value, be judged to be extremely, according to surpassing grade output signal output L21, L22, L23.
In the situation that judgement is the common operation of lift appliance be there is no to the process observation grade of obstruction, to control device for running the engine 12 output signal output L21.Control device for running the engine 12 records receive the situation of output signal L21, but to towing machine 4 and emergency braking device 9, do not give an order.And service personnel is confirmed the reception historic records of the output signal L21 in control device for running the engine 12 when periodic inspection, if received, thickly carry out the maintenance of main rope 3 and driving rope sheave 5 week.
In the situation that judgement is likely common operation to be produced to the service stopping grade hindered, to control device for running the engine 12 output signal output L22.When control device for running the engine 12 receives output signal L22, by telephone line etc., require service personnel to go to work, stop the service of lift appliance.
In the situation that judgement is the emergent stopping grade that need to stop at once, to emergency braking device 9 output signal output L23.Emergency braking device 9 is when power supply is cut off, and controls the brake equipment of the fail safe type that 3 pairs of cars 1 of main rope are braked, and according to output signal L23, cuts off the electric power of emergency braking device 9 is supplied with.
And, control device for running the engine 12 carries out the confirmation of car internal loading and car call termly, in order to enter checking mode, but in the situation that repeatedly carry out also not entering checking mode after the regular confirmation of pre-determined number, rest in destination floor and make elevator under the passenger, then do not carry the passenger, with the car call, independently force to enter checking mode, and outgoing inspection mode signal C1.
State monitoring method according to this lift appliance, travel to and fro between the departure of the driving rope sheave position on the Jian Shi fixed position, test zone in hoistway according to car 1, carry out abnormality juding, thereby do not need to detect the unit (the governor coder 23 in embodiment 1) of the amount of movement of car 1 or main rope 3.And, owing to confirming unmanned and not having the state of call to be checked, thereby can not reduce elevator service.In addition, when in the situation that do not checked in during fixing, force to enter checking mode, thereby can be checked more reliably.
In addition, in embodiment 3, set the threshold to three phases, but stage quantity is not limited to three.
And, upper position display panel 56 is configured in to top layer in embodiment 3, lower position display panel 57 is configured in to the bottom, and checks that the interval of advancing of use is not limited to this.But, be preferably set to the above distance of the needed distance of car 1 lifting one deck floor.Thus, threshold value TH1, TH2, TH3 and lifting travel independently can be made as to fixed value.
In addition, in embodiment 3, the initial point between test zone is made as to the detection position of lower position display panel 57, but also can be using the detection position of upper position display panel 56 as initial point.
In addition, in embodiment 3, when checking, make car 1 come and go, but also can only carry out the rising running between predetermined test zone, only carry out the decline running between predetermined test zone.In this case, detection unit 54 is by difference delta D1(=|D11-D12|) from the test zone measured in advance between the difference delta D=|D20-Δ D1| of length D20 and the value of threshold value TH1～TH3(TH1～TH3 be because of the different value of inspection method) compare, judge thus extremely, described difference delta D1 is the position signal D11 that just received the motor encoder 11 after checking mode signal C1, the difference of the position signal D12 of the motor encoder 11 after just having stopped with checking mode C1.And, in this inspection method, can carry out the rising running of car 1 and the running both sides that descend, also can carry out twice continuously checking mode.
And between test zone, detecting unit is not limited to the structure of embodiment 3, for example, also a plurality of switches that arrange in hoistway and the operating sheet for operating switch be arranged on car 1 can be combined.
In addition, the emergency braking device 9 of the type of controlling main rope 3 has been shown in embodiment 1～3, but emergency braking device 9 is so long as the device of independently car 1 being braked with towing machine 4 can be also the emergency braking device of other type.
