Description
Technical field
The present invention relates to the elevator of vibration absorber is provided with car in order to suppress the oscillation crosswise of car.
Background technology
In order that car is provided with along guide rail stably oscilaltion, in elevator makes roller from three directions and guide rail contact
Guide device.The power that the roller direction guiding rail compresses is adjusted by setting spring on the bar for be provided with roller.If guide rail is curved
Song installation or guide rail seam have jump, then external force is delivered to car by the roller with guide rail contact, produce oscillation crosswise.
It is to carry out strict control to cause guide rail as disturbing source as one of method for suppressing this car oscillation crosswise
Bending or jump be in reference for installation.In addition, car is by manned cage and installation cable or the car of guide device
Frame is formed, and cage is connected with car frame by yielding rubber, so that vibration is not easy to be delivered to cage from car frame.
However, it is difficult to ensure that scene there are those of skill in the art, particularly it is difficult to maintain car guide rail installation accuracy in overseas.
For example, in patent document 1, what is be integrally formed along the guide rail, cage and car frame that are disposed in hoistway
In lift car, the direction of vibration and magnitude of vibrations of lift car are detected, the active damping for the vibration cancellation for making to detect is set
Device.

The content of the invention
The invention technical task to be solved
In addition, the technology described in patent document 1 discloses, controller sends driving instruction to motor so that with by
The vibration cancellation that acceleration transducer detects.It is subtracting costly if however, use servomotor in vibration control
Vibrating device, cost uprise.For example, although the motor response performance for carrying out common speed control is poorer than servomotor,
It is more inexpensive, therefore being capable of control cost.If in addition, making control system be always running status, energy consumption increases.
It is therefore an object of the present invention to solves above-mentioned problem of the prior art, there is provided inexpensive and small energy consumption elevator vibration damping
Device.
For solving the technical scheme of problem
In order to reach above-mentioned purpose, elevator of the invention has vibration absorber, and the vibration absorber has：Detect lift car
Vibration acceleration accelerometer；Controller, when vibration acceleration exceedes predetermined threshold value, determined based on vibration acceleration
Determine the controlled quentity controlled variable of motor, the direction of car acceleration when exceeding threshold value based on vibration acceleration determines the rotation of motor
Direction；With the motor according to the control instruction driving from the direction of rotation comprising controlled quentity controlled variable and motor of controller output.
Invention effect
In accordance with the invention it is possible to provide inexpensive and small energy consumption damping device for elevator.

Embodiment
Be described in detail below for embodiments of the present invention using accompanying drawing, but the present invention be not limited to it is following
Embodiment, various modifications example and application examples in technological concept of the invention are also contained in the range of it.
Fig. 1 is the elevator legend of the vibration absorber with the present embodiment.In Fig. 1, vibration damping dress is installed in the bottom of car 1
Put.There is the vibration absorber its one end to be installed on car 1, the other end is provided with the connecting rod 3 of counterweight 2, and one end of connecting rod 4 is rotatable
Ground is installed between the abutment for being installed on the counterweight 2 of connecting rod 3 and being installed on car, and the other end of connecting rod 4 is rotatably mounted
In one end of connecting rod 5.The other end of connecting rod 5 is installed on the rotary shaft of motor 6.When the driving electric arbor of motor 6 rotates, bag
Oscillator counterweight 2 in the mechanism of connecting rod 3, connecting rod 4, connecting rod 5 is included to swing centered on the abutment for being installed on car.To motor 6
Information of the control instruction based on accelerometer 7 generated by controller 8.Vibration absorber mechanism part is being arranged at the bottom of car 1
Mounting seat 9 is set.If the control panel for being built-in with accelerometer 7 and controller 8 is arranged at into mounting seat 9, one can be used as
Vibration absorber processing is covered, therefore the setting to car 1 becomes easy.
That is, the elevator of the present embodiment has vibration absorber, and the vibration absorber has：Detect the vibration acceleration of car 1
Accelerometer 7；When vibration acceleration exceedes predetermined threshold based on vibration acceleration come determine the controlled quentity controlled variable of motor (control
Size), the direction of car acceleration when exceeding threshold value based on vibration acceleration determine the control of the direction of rotation of motor
Device 8；With the control instruction of the direction of rotation comprising controlled quentity controlled variable and motor exported according to controller 8 come the motor 6 that drives.
Further, the controller 8 of vibration absorber can also be not above in vibration acceleration within the time set in advance
During threshold value, decide not to motor 6 and export the control instruction from controller 8.
Further, vibration absorber also includes the counterweight 2 with quality and the rotary actuator for swinging counterweight 2,
Vibration absorber is arranged at lift car.
Further, in vibration absorber, in order to suppress the oscillation crosswise of lift car 1, one end of connecting rod 3 (first connecting rod) can
It is rotatably engageable that counterweight is installed in the other end in car, the motor 6 for rotating first connecting rod is configured in car 1, even
Bar 5 (second connecting rod) is engaged in the rotary shaft of motor 6, has connection connecting rod 3 (first connecting rod) and connecting rod 5 (second connecting rod)
Connecting rod 4 (third connecting rod), connecting rod 5 (second connecting rod) are shorter than connecting rod 4 (third connecting rod), and connecting rod 5 (second connecting rod) can be than connecting rod 3
(first connecting rod) is short.
Fig. 2 is the mechanism section legend of the vibration absorber of the present embodiment.The connecting rod 3 for installing counterweight 2 can via rotary shaft 10
It is rotatably arranged in mounting seat 9.Connecting rod 3 is rotatably coupled with connecting rod 4 by rotary shaft 11.In addition, connecting rod 4 with connecting rod 5 by revolving
Rotating shaft 12 is rotatably coupled, and connecting rod 5 is connected via rotary shaft 13 with motor 6.Connecting rod 5 is using motor 6 with rotary shaft 13
Centered on rotate clockwise or counterclockwise, the rotation that connecting rod 3 follows connecting rod 5 via connecting rod 4 moves back and forth in the lateral direction.Make
For an example, as shown in Fig. 2 the connecting rod 4 when making connecting rod 3 and the connecting rod 5 be located at vertical direction is with angle formed by horizontal direction
θ, the distance for making rotary shaft 10 and rotary shaft 11 in connecting rod 3 is L1, the distance of rotary shaft 12 and rotary shaft 13 is L2 in connecting rod 5
When, torque Tws of the motor torque Tm with acting on connecting rod 3 relation is as follows.
Tw=Tm × L1/L2
Thus, L1/L2 is bigger, it becomes possible to acts oscillator with smaller torque Tm.
Fig. 3 is the illustration that the accelerometer of the present embodiment exports, in the example of output for representing accelerometer 7
The horizontal vibration acceleration of car 1.Fig. 3 dotted line represents the threshold value of acceleration, and TH+ is the threshold value of positive side, and TH- is minus side
Threshold value.Accelerometer exports if it exceeds the threshold value, then instruct to the output control of motor 6.In section A as shown in Figure 3 and
Interval B illustrates the relation with accelerometer output.In the A of section, accelerometer output first exceed threshold value be in threshold value TH-,
If being set as that motor turns clockwise when first more than TH-, then accelerometer output is first more than threshold value in interval B
In TH+ sides, therefore now motor is rotate counterclockwise.
