The specific embodiment
Below, with reference to accompanying drawing one embodiment of the present invention is described.
As the vibration in the elevator driving process vibration of above-below direction and horizontal vibration are arranged.The constrained oscillation that the vibration of above-below direction causes because of off-centre of torque pulsation (torque ripple), rope sheave and the pulley of the electrical motor of winch etc. propagates on the hoist cable and produces.Therefore, the offset that needs to reduce the pulsation of electrical motor and dwindle swivel.
Horizontal vibration mainly because of the bending of guide rail and ladder poor force displacement to be delivered on the lift car to produce.In express elevator, because of the oscillation frequency rising of bending.In order to reduce lateral vibration, need to manage so that the installation error of guide rail diminishes or in the bottom of guiding device and lift car vibration-proof rubber is set or shock absorber comes vibration is decayed construction.
In addition, as the vibration in the lift car driving process (rocking of lift car), mainly contain motion of translation and luffing, for two kinds of mode ofs vibration effectively suppressing this two kinds of mode ofs vibration, preferably dwindle to be excited as the response of the floor of estimating the position and the phase difference between the above-mentioned input (forcing the displacement waveform).Dwindling of this phase difference, the rigidity of the center-of-gravity position that can produce a very large impact by the dynamic characteristics that changes lift car and guiding device etc. realizes.Yet, in order to change center-of-gravity position, for example can place weight in top or the bottom of lift car, the quality that can cause lift car increases and the radical of hoist cable increases but do like this.In addition, the configuration of equipment that also can be by changing large quality changes center-of-gravity position, but owing to being subject to the restriction of size etc., therefore is difficult to realize.
And then even determine the design value of the rigidity of guiding device temporarily, but the actual conditions of erecting stage are always not consistent with design value yet, and the rigidity that therefore can change simply at the scene guiding device gets final product.
Fig. 1 is the block diagram of the lift car 1 of elevator.In the following description, will be set as directions X with respect to the depth direction in lift car 1 front, horizontal direction will be set as Y-direction, above-below direction will be set as the Z direction.
In elevator, lift car 1 and counterbalanced weight are linked by hoist cable 3, and are driven by winch (not shown).Hoist cable 3 is arranged on the position of substantial middle above lift car 1.In the hoist trunk of elevator, be provided with guide rail 2a, the 2b of the pair of right and left with T font cross section along vertical direction, lift car 1 is along guide rail 2a, 2b oscilaltion.Top and bottom at lift car 1 are provided with the various devices such as not shown door drive, rope end, guiding device and emergency braking apparatus.
The length of guide rail 2a, 2b because above-mentioned guide rail 2a, 2b are installed in the mode that links in the vertical, therefore can produce ladder at each point of connection poor and crooked between 4～5m.Poor and the crooked conduct of this ladder forces displacement and acts on the lift car 1.In order to prevent forcing Vibration propagation that displacement causes to lift car 1 by this, the guiding device that guides lift car 1 lifting across guide rail 2a, the 2b of T font is set at up and down 4 positions of lift car 1.
Guiding device possesses rod member and by pressing spring, this rod member is at the centrally-pivoted axle supporting deflector roll of deflector roll, and can rotate around fixing fulcrum, this presses the spring press deflector roll, and the rigidity of guiding device refers to the rigidity that contacts between lift car and the guide rail of center position of the deflector roll that joins with guide rail.Therefore, in order to improve the rigidity of guiding device, can improve the rigidity of deflector roll rubber, improve the spring constant press pressing spring, perhaps increase rod member from fulcrum to the distance of pressing spring position and the lever ratio namely of the ratio the distance from fulcrum to the deflector roll center.But, because the rigidity of deflector roll rubber exceeds a lot (more than 10 times) with comparing by pressing spring, so the rigidity of guiding device (=equivalent spring constant: be scaled the spring constant at the center position of deflector roll) is by the lever ratio decision of the spring constant of press pressing spring and rod member.
In order to suppress Vibration propagation, deflector roll adopts rubber to make, and this deflector roll links with lift car 1 across spring.Rod member at the pivot suspension deflector roll arranges shock absorber.In order to reduce the vibration of lift car 1, can reduce the transmission of vibration rate by the rigidity that reduces guiding device, but then, rocking of lift car 1 when the rigidity of reduction guiding device can cause the passenger to take advantage of into lift car 1 becomes large, therefore the rigidity of guiding device need to be set in more than the certain value.
In Fig. 1, the standby vibration damping of tool for mounting is with the guiding device of actuator below the left and right sides of lift car 1.Actuator 21a be used for deflector roll 11a towards linking by pressing spring 12a that guide rail 2b presses.On the Y-direction on the directions X in left side and right side, also be provided with actuator, above-mentioned actuator respectively with press pressing spring and link.
At lift car 1 acceleration pick-up 20a, the 20b that detects vibration is set, detects respectively the acceleration/accel of fore-and-aft direction and horizontal this both direction.Actuator 21a, 21b, 21c carry out controlled reset according to the signal that is detected by acceleration pick- up 20a, 20b, and drive in the mode of the vibration of eliminating lift car 1.Acceleration pick- up 20a, 20b are arranged on the below of lift car 1, but are not limited in this position, also can only arrange up, perhaps both arranged up also below arrange.In order to detect lift car around the rotatablely moving of Y direction, different positions arranges acceleration pick- up 20a, 20b on the short transverse of lift car.
Fig. 2 represents guiding device that the shock of elevator car of the directions X of Fig. 1 is controlled.Guiding device for by two deflector roll 9a, 9b from about clamp guide rail (not shown) structure.Deflector roll 9a, 9b utilize bolt 71a, 71b that middle body and rod member 36a, 36b are linked.Rod member 36a, 36b are fixed by pedestal 33a, 33b and bolt 32a, 32b, and pedestal 33a, 33b are fixed on the downside of lift car 1.Spring 12a, the 12b that deflector roll 9a, 9b direction guiding rail are pressed adopts coil spring, and it is positioned at the position of side on the lower than deflector roll 9a, 9b central authorities.
Movable piece 40 is fixed on rod member 36a, the 36b through excellent part 45a, 45b, and can adjust the pressing quantity of spring 12a, 12b.Actuator 21a has electrical motor 41 and ball-screw 42, and links with movable piece 40.Movable piece 40 has the Linear guide 39 of the motion of constraint above-below direction, thereby can only move in the horizontal direction.
In order to dwindle the height h of guiding device integral body, fulcrum 32a, the 32b of rod member 36a, 36b is arranged to central authorities near deflector roll 9a, 9b, and makes the projecting section of fulcrum of rod member 36a, 36b overlapping in paper vertical direction and deflector roll 9a, 9b.And, be at deflector roll 9a, 9b and offer porose 34a, 34b circle-shapedly, at pitch circle 35a, 35b bolt 32a, 32b are set.Thus, deflector roll 9a, deflector roll 9b, rod member 36a, rod member 36b and pedestal 33a, pedestal 33b do not interfere and overlapping on short transverse in the paper vertical direction, thus reduced height h.
Fig. 3 is the side sectional view of expression deflector roll 9a, deflector roll 9b, rod member 36a, rod member 36b and pedestal 33a, the configuration of pedestal 33b on directions X.Deflector roll 9b, rod member 36b and pedestal 33b all arrange in nonoverlapping mode.If bolt of rear end plate 32 is inserted from the left side, and passes the hole 34b that is opened on the deflector roll 9b, then rod member 36b and pedestal 33b can be linked up.
The rigidity of guiding device is arranged to: less to the distance b of rod member fulcrum from the center of deflector roll, larger apart from a from the center of deflector roll to spring position, then the rigidity of guiding device is larger.Be altered to position 38a, the 38b shown in the dotted line by the position with spring 12a, 12b, can change the rigidity (equivalent spring constant) of guiding device.By making the rod member fulcrum move to position near the deflector roll center, can increase fulcrum to deflector roll center and the lever ratio of fulcrum to spring position, so can increase equally the variable quantity that spring position changes (a → a ') caused rigidity.
Thus, in the time need to changing the rigidity of guiding device in the erecting stage, there is no need to prepare the different multiple spring of spring constant, can adjust simply operation.In order to change the position on short transverse of spring 12a, 12b, be provided with groove 48 (Fig. 3) at the length direction of rod member 36a, 36b, thereby slided in the position of spring 12a, 12b.In Fig. 2, be provided with and a plurality of excellent part 45a, 45b be fixed on hole (not shown) on the movable piece 40, make it possible to size a is adjusted.In addition, also can between pillar 31 and pedestal 44, cushion block 46 be set and adjust spring position.
Then, the schematic diagram with reference to the mode of vibration on the XZ plane of Fig. 1 describes.Fig. 4 represents actuator 21a is arranged on the lift car bottom and the motion of lift car when vibrating.
(the most extreme state is for respect to inputting the displacement waveform for situation when Fig. 4 (a) of top and Fig. 4 (b) are illustrated in ground Board position 53 place's translational vibration patterns and pitch vibration pattern and vibrate in the same direction, the phase difference of the response displacement waveform of two mode ofs vibration is 0 ° state), the situation of the opposite direction of Fig. 4 (c) and Fig. 4 (d) expression and Fig. 4 (a) and Fig. 4 (b) (the most extreme state is that the phase difference of the response displacement waveform of two mode ofs vibration is 180 ° state with respect to input displacement waveform).Above-mentioned diagram is the state that holds intelligible condition most.Vibrational state when the figure of the figure of the rightmost side of top and the rightmost side of below represents that above-mentioned two kinds of mode ofs vibration overlap each other.
The initial condition of the dotted line 52 expression lift cars among the figure, the state when solid line has represented to occur vibration.In the translational vibration pattern of Fig. 4 up (a), elevator moves towards the left side, moves in order to suppress this, need to utilize actuator 21a to apply control effort towards the right side to lift car.This control effort can also suppress the pitch vibration pattern of Fig. 4 (b) equally.
On the other hand, below Fig. 4 (c) and Fig. 4 (d) in, when suppressing the translational mode of (c), with the situation of Fig. 4 (a) in the same manner, utilize actuator to apply control effort towards the right side to lift car.This control effort is not to act on the direction of the pitch vibration pattern that suppresses Fig. 4 (d), but acts on a side of the rotation that increases lift car.Thus, in the situation that only below actuator is set, by carrying out and to dwindle separately (it is desirable to phase difference and be 0 and be the state of Fig. 4 of top (a) and Fig. 4 (b)) structure design with respect to the phase difference of input for the response of Fig. 4 (a) of top and two mode ofs vibration shown in Fig. 4 (b), thereby can improve effectiveness in vibration suppression.
Fig. 5 represents the result of calculation of the phase difference of the translation (TX) on XZ plane of lift car and each mode of vibration in these two mode ofs vibration of pitching (RY).Transverse axis represents the rigidity ratio that the rigidity of the guiding device of upside obtains divided by the rigidity of the guiding device of downside.The rigidity of guiding device is the equivalent spring constant (N/mm) that is scaled at the center position of deflector roll, in fact by deciding by the spring constant of pressing spring and the lever ratio of rod member.
In addition, Fig. 5 is the scaling system of calculating the phase difference of two mode ofs vibration according to the phase place of forcing the transfer coefficient that is displaced to the floor acceleration/accel that guiding device up and down bears.Transfer function adopts the mechanical model that has two degree of freedom of translation and pitching in the rigid body pattern of a particle shown in Fig. 5 upper right side.At first, guiding device up and down is set as respectively k
0, and will be up and down identical and be k
0Situation (rigidity ratio up and down is in 1: 1 relation) be defined as initial configuration.Therewith relatively, the rigidity of up and down guiding device is set as respectively a doubly and b times, to carry out ak
0And bk
0Structure modify.Fig. 5 is the result of calculation of the phase difference of two mode ofs vibration when being set as a=1 and b=2.At this, if the rigidity ratio is defined as a/b, then the rigid phase of rigidity and the opposing party's the guiding device of the guiding device of larger, the expression upside of a/b is than larger; A/b is less, the rigidity of the guiding device of expression downside is larger with the rigid phase ratio of the opposing party's guiding device.
In the situation that elevator, because guiding device up and down is by same guide pass, therefore identically force the displacement input action on lift car.Can produce the speed of resulting from, up and down time difference that interval and rail length are set of guiding device in the input of up and down guiding device.Therefore, as shown in Figure 5, the phase difference of rise operation and two mode ofs vibration when moving that descend is different, so trend separately is different.
As shown in Figure 5, in rise operation and decline operational process, when the rigidity ratio (=when a/b) being in 0.2～0.5 the scope, phase difference diminishes.Need to prove, though not shownly in this diagram of curves go out other situations, be not limited in b=2, except the condition of a=0.5 and b=1, also can change to a=1 and b=3 etc., at this moment, can obtain roughly the same diagram of curves.
In the elevator of reality, according to vibration performance, when being set as b=5 when above, the rigidity of guiding device becomes really up to the mark, becomes responsive with respect to the unfairness of guide rail, does not therefore have practicality aspect the vibration that reduces lift car 1.
Therefore, preferably in design with the rigidity ratio (=a/b) be set as 0.2～0.7, more preferably with the rigidity ratio (=a/b) be set as 0.2～0.5, preferably the rigidity of the guiding device of downside is set as 1.5 times～5 times of rigidity of the guiding device of upside, more preferably is set as 2 times～5 times.
Fig. 6 is the block diagram of feedback control system, is the block diagram for the control system of the vibration of rotating to the translational vibration of directions X with around Y-axis and two actuator 21a, 21b carrying out vibration damping around the vibration that Z axis rotates.
For the signal of removing clutter, make the acceleration pick-up 20a that is installed in lift car below and acceleration pick-up 20b by low-pass filter 62a, 62b.Then, above-mentioned signal is input among controller 63a, 63b, 63c, the 63d side by side, the control command 65a of actuator (21a among Fig. 1) be the synthetic of controller 63a, 63c and, the control command 65b of actuator (21b among Fig. 1) be the synthetic of controller 63b, 63d and.Need to prove, in order to prevent the excess current flow toward actuator, clipper 64a, 64b are set respectively.
Controller is a kind of in robust control (robust control) method of designing, can be designed to the uncertain part in the control object is considered as external interference signals and process, use the H ∞ control theory etc. of probabilistic impact of suppression mode, carry out frequency shaping with the weighting function of the travelling comfort of considering human body etc.According to this control design, except consisting of controller 63a, 63b, 63c, 63d, in order to adjust at the scene, can also be consisted of by proportional control and phase compensator.
Fig. 7 represents the effectiveness in vibration suppression analog result relatively of initial configuration and the structure of comparing the phase difference that has dwindled two mode ofs vibration with initial configuration.There is shown the acceleration/accel with the ground Board position when lift car simulates poor step-like of ladder and forces displacement to be applied to upside guiding device and downside guiding device in the mode with time difference.Compare with the situation about not controlling of Fig. 7 (a), Fig. 7 (b) controls in initial mechanism, confirms thus approximately to have reduced about 40% vibration.Therewith relatively, according to present embodiment, further improve effectiveness in vibration suppression, compared with situation about not controlling, approximately reduced about 70% vibration.
In addition, in the above description, to the center-of-gravity position 54 of lift car 1 be positioned at than the center of gravity of short transverse on the lower the position and the structure that only is provided with actuator 21a at downside be illustrated, and when the center-of-gravity position 54 of lift car 1 is positioned at the top of center of gravity, if actuator 21a is arranged on upside, and the rigidity of the guiding device of upside is set for higher than the rigidity of the guiding device of downside, then obtain identical effectiveness in vibration suppression.
As mentioned above, according to present embodiment, a plurality of mode ofs vibration of the lift car when making vibration vibrate in the same direction with respect to the unfairness of guide rail, and will be set as from the vibration transmission gain of guide rail from the recently vibration transmission gain from the guiding device of upside of the vibration transmission gain of the guiding device of downside large, therefore actuator is arranged on the downside of lift car, thus so that with respect to the input from downside, the phase difference of these two mode ofs vibration of the translation of lift car and pitching (pitching) in the position, floor (with actuator the side equivalence is set) diminish.
Particularly, the rigidity with guiding device setting up and down is not distributed into identical rigidity, but sets the rigidity of the guiding device of downside for than upside height, forms non-symmetrical rigidity.In addition, dwindle the fulcrum of rod member of pivot suspension deflector roll and the distance between the deflector roll center, the spring fixed part of rod member is set in position away from the deflector roll center, even so that use identical spring, also can improve the rigidity of guiding device.That is to say, can be equivalent to expansion from fulcrum to the deflector roll center and the lever ratio from the fulcrum to the spring position.
In addition, for the position of the fulcrum that makes deflector roll and rod member approaches, the fulcrum of rod member is arranged in the projecting section of deflector roll.To be arranged on as the bolt of rear end plate of fulcrum with uniformly-spaced and be on the pitch circular hole that is opened on the deflector roll circle-shapedly, utilize above-mentioned hole, and can easily be linked the pedestal of rod member and guiding device by bolt.And then, at rod member groove is set, makes it possible to change at above-below direction the spring position of pressing of deflector roll, thus can be in the situation that do not need to change spring, easily change at the scene the rigidity of guiding device, can save installation exercise and adjust the required time of operation.In addition, owing to the distance between the pedestal of the center that can shorten deflector roll and guiding device, therefore can dwindle the height of lift car.
