It forms.In addition, for the concrete structure of these traction machines 11, braked body 13 and brake apparatus 14, due to not having with the present invention
Direct relation thus omit.
In contrast, the control device 7 of lift appliance 1 includes the computer for being equipped with CPU, ROM, RAM etc., with traction machine
11 are arranged on together in Machine Room etc..The control device 7 has operation control function when lift appliance 1 is usual to be run, and
With each function of abnormity detection portion 22, operation control part 23 and exterior portion 24 of being in case of emergency used to stop controlling.
Operation control during in order to usually be run and stopping control in emergency circumstances, the control dress of lift appliance 1
It puts 7 and is taken into the speed of service of car 3 as its input.Therefore, the setting of 1 side of lift appliance with the action of car 3 in linkage,
The governor (governor) 15 driven by governor rope 16.The governor 15 is for the speed of service for detecting and adjusting car 3
And set, it is equipped with speed detector 21 in governor 15.The rotating speed of the speed detector 21 detection governor 15 and output
To the operation control part 23 of control device 7.
Operation control part 23 in control device 7 calculates the speed of car 3 according to the revolution of governor 15 first.Herein
On the basis of, drive signal S1 is applied to the motor (not shown) for rotating the rope sheave 12 of traction machine 11 in usual operation, it will

The detailed description of row control.
It is handled to carry out the reply of control device 7 in emergency circumstances, the abnormity detection portion 22 in control device 7 detects
It must carry out unit exception and the control exception that the operation of lift appliance 1 stops.Operation control part 23 is by abnormity detection portion 22
In the case of detecting exception, washout S2 is applied to the brake apparatus 14 set in traction machine 11, passes through application
Emergency Negative Thrust controls its action.In addition, the drive signal for traction machine also can be made when sending out washout S2
S1 is reduced rapidly also based on washout S2, as a result, lift appliance 1 carries out stopping behaviour using the rapid of inverter
Make and stopping operation both rapidly and stop operation using brake apparatus.
In addition, it in Fig. 1, in order to carry out the judgement of operation control part 23 in emergency circumstances processing, is stored in table 24
Reference speed of car speed during emergent stopping etc..Operation control part 23 refers to the table 24, more than defined car speed
Operating status in emergency braking number when reaching certain value, limit the normal speed of later elevator.
Fig. 2 is the flow chart for the processing action for representing the control device 7 when emergent stopping occurs.Action is controlled using the figure
Process flow of the portion 23 processed when emergent stopping occurs illustrates.In addition, regulation is read in by the control device 7 for computer
Program and perform the processing shown in following each flow chart.
In the step S101 that Fig. 2 most starts, detected by abnormity detection portion 22 must make lift appliance 1 operation stop
Abnormal, operation control part 23 receives the information and sends out control device action command S2 (washouts in step s 102
S2), act brake apparatus 14 in step S103.In addition, in the processing of step S102, washout S2 is being sent out
While, it is also effective that the drive signal S1 for being sent to traction pusher side is made, which to be reduced rapidly also based on washout S2,.
In the processing of step S104, (braking start time) the reading speed at the time of action that confirmed brake apparatus 14
The velocity amplitude Vc (detection speed) of car 3 that degree detection device 21 detects.In addition, about the reading opportunity, which can be with
The abnormality detection of abnormity detection portion 22 carries out in linkage, such as in step S102 or when step S103 carries out.In step S102
Several errors can be generated, but the difference can be susceptible in advance with the speed measured during step S103.
Then, the speed data V0 (reference speed) being set in advance in exterior portion 4 is taken into step S105.In step S106
In, the magnitude relationship of judgement detection speed Vc and reference speed V0.In addition, the car detected when brake apparatus 14 acts herein
3 velocity amplitude, that is, detection speed Vc is braking commencing speed.
Comparing to determine on the basis of result is braking commencing speed Vc in the case of more than speed V0, in step in step S106
+ 1 is counted to accumulative emergency braking times N in rapid S107Y, in the case where braking commencing speed Vc is less than reference speed V0,
Do not change the value of accumulative emergency braking times N in step S107N and maintain.Thus the high speed fortune more than reference speed is stored
The emergency braking number gone.
Then, emergency braking number data N0 (the accumulative emergency braking benchmark set in reading table 24 in step S108
Number), judge to add up the magnitude relationship of emergency braking times N and accumulative emergency braking benchmark times N 0 in step S109.
Judgement result in step S109 is that accumulative emergency braking times N is accumulative more than 0 emergency braking benchmark times N
In the case of, carry out step S110Y.It is selected in step S110Y, from this moment, by moving after elevator recovery
Make control unit 23 normal speed Vmax is limited to V ' and is run.And the notification to service companies is carried out in step S111,
Thus maintenance personnel is reminded to carry out readjusting for brake apparatus.
On the other hand, the judgement result in step S109 is that accumulative emergency braking times N is less than accumulative emergency braking base
In the case of quasi- times N 0, do not change the value of normal speed in step S110N and continue the operation of elevator.
In this way, after the emergency braking number more than specified car speed reaches certain value, by moving after elevator recovery
Make control unit 23 to run with limiting normal speed, cause to rub thus, it is possible to which the emergent stopping in high-speed cruising is inhibited to be repeated
The abrasion aggravation of component is wiped, the decline of stopping power caused by preventing it from influencing.
In addition, reference speed V0 at this time and a reference value of accumulative emergency braking benchmark times N 0, according to the electricity applied
Terraced specification, the structure of brake apparatus, the rate of wear data of rated braking torque and friction means are set in the system of brake apparatus
In the range of kinetic force will not reduce.
(it is more than the speed model of reference speed V0 when lift appliance is only to high-speed cruising by the process flow of above-mentioned Fig. 2
Enclose) emergency braking number counted and added up, the cumulative number be more than benchmark number in the case of, limit lift appliance
Run to later normal speed.Specified speed of service after being limited at this time can be less than reference speed V0, as a result, i.e.
Make the emergency braking in generation specified speed of service it is also possible that the influence to the abrasion of brake apparatus is limited in irreducible minimum
Degree.
In addition, being able to confirm that the abrasion degree of brake apparatus by the contact (step S111) with service companies, as a result continue
The confined specified speed of service state is carried out until the safe operations such as the replacement of brake apparatus are confirmed, by safeguarding people
Member confirmation and be restored to original high-speed cruising state.
In addition, in practical design, reference speed V0 and accumulative emergency braking benchmark times N 0 allow for braking dress
The abrasion put and set, preferred reference speed V0 is set in the 60 to 90% or so of normal speed, adds up emergency braking benchmark
Times N 0 is 10 times or so.In addition, car speed when limitation when reaching accumulative more than 0 times N of emergency braking benchmark is run
Be preferably provided at below reference speed V0 50% or so and run.
It in the present invention formed in this way, can inhibit that emergent stopping is repeated and leads to friction means during high-speed cruising
Abrasion increase, can prevent its influence caused by stopping power decline.In addition, with the setting detection friction near rubbing surface
Compared with the mode of the switch of the distance change of braking surface, the present invention does not need to set other devices in brake apparatus in face, because
This is capable of the miniaturization of realization device entirety.
The effect of the present invention and embodiment is further described in detail.Usually, it is known that the braking dress of lift appliance
Putting the rate of wear of the friction means of the middle resinae used has the more high temperature then bigger tendency of rate of wear, the friction of brake apparatus
The abrasion loss of component is related with the pushing face pressure and sliding distance to braked body.
The sliding distance of friction means during emergency braking is related with the kinetic energy that the system of lift appliance integrally has, elevator
Normal speed when becoming 2 times, the sliding distance of friction means becomes about 4 times.In addition the frictional heat generated in braking to rub
Wiping face becomes high temperature, therefore the rate of wear increase of friction means, abrasion aggravation.
Therefore, when being damaged when worrying because the emergency braking repeatedly in high-speed cruising to friction means, temporarily with limit
The aggravation that the mode of the normal speed of elevator processed runs the abrasion to inhibiting friction means has very big effect.And pass through
The decline of stopping power, can obtain stable brake force caused by preventing its influence.
Deformation, alternate embodiment then for the present invention illustrate.The present invention is not limited to above-described embodiment,
Do not depart from the present invention purport under conditions of include it is conceivable that various modes.Such as speed detector in the present embodiment
21 are set to governor 15, but may also set up in the motor of other devices such as traction machine.
In addition, multiple reference speed V0 and accumulative emergency braking benchmark times N 0 can also be set separately, such as there are two types of
(V0, V0 ' and N0, N0 ') in the case of, after the judgement (step S109) of accumulative emergency braking times N shown in Fig. 2, repeat
Judgement (step S105~S109) to next reference speed V0 ', accumulative emergency braking benchmark times N 0 '.It at this point, also can be to two
Kind number data N1, N2 are judged (step S109) using respective stored count number.
In addition, the control device 7 of the present invention is not limited to be applied to be configured in the Machine Room at 2 top of liftway
