The specific embodiment
Use accompanying drawing to specify an example of lift car of the present invention below.
Fig. 1 representes the relation between framework and the active mass damper mounted thereto (below be called AMD) of the lift car of this example, (a) is birds-eye view, (b) is front view.The framework of this car is the framework that the prior art of the positive door, side panel and the top board that do not have expression among the figure is installed.That is, afterwards above-mentioned positive door, side panel and top board are installed on this framework and are assembled into lift car.
The framework of this car at first, is described.Among Fig. 1, the plan view shape of car floor 11 is a rectangle.At the two ends that become a positive limit (bottom among Fig. 1 (a)) of this car floor 11, the perpendicular pair of right and left longeron 12 that is provided with.This uses the receptacle material that is made up of angle steel etc. to longeron, below is referred to as and supports 12.Link respectively crossbeam 13 is arranged supporting 12 upper end at this.This also uses the receptacle material that is made up of angle steel etc. to crossbeam 13, below is called transverse arm 13.This is attached on the upper end of cooresponding support 12 to an end of transverse arm 13 as stated, and (top of Fig. 1 (a)) disposes along depth direction the other end towards the back side.And, connect to one with the positive door of not representing among the support figure and the door machine base 14 (having omitted diagram among Fig. 1 (b)) of switching mechanism thereof between the top of pair of right and left support 12.Between this machine base 14 and pair of right and left transverse arm 13, be provided with the oblique straining beam 15 in top, strengthen ceiling structure.
At the central part of the depth direction of pair of right and left transverse arm 13, be provided with integratedly along this cross-directional and put the beams in place 16 transverse arm 13.This upper beam 16 is made up of 2 parallel channel-section steels, configuration above car.At the downside of car floor 11, be provided with the underbeam of supporting below it 17.This underbeam 17 is made up of 2 channel-section steels equally, along Width (left and right directions of Fig. 1) configuration of car floor 11.Link with the vertical frame 18 of pair of right and left respectively between the two ends of these upper beams 16 and underbeam 17.This to vertical frame 18 for configured in parallel respectively the member of 2 angle steel; Be provided with along the longitudinal direction respectively; Be in and two lateral surfaces of a pair of transverse arm 13 and the dual-side state of contact of car floor 11, their upper and lower end parts is bonded to respectively on the end of upper beam 16 and underbeam 17.
Shown in Fig. 1 (a), car sheave beam 19 is being installed on the upper beam 16 with respect to the 16 predetermined oblique angle ground of putting the beams in place on the birds-eye view.Shown in Fig. 1 (b), this car sheave beam 19 has from clipping the member of the 16 parallel configuration of putting the beams in place up and down.As shown in Figure 2, this member is for assemble the structure of the channel-section steel of pair of right and left up and down abreast.In addition, Fig. 2 sees the figure of car sheave beam 19 for the end direction of the car sheave 20 stated after installed, has omitted 16 the diagram of putting the beams in place.Shown in Fig. 1 (a), the two ends at the length direction of this car sheave beam 19 can be provided with car sheave 20 respectively rotatably, the rope that being surrounded with does not have expression among the figure suspension car is used.
Wherein, because car sheave beam 19 has been installed as above-mentioned obliquely, therefore when many ropes of expression are not meshed with the groove 20a of car sheave 20 shown in Figure 2 among the figure, meshing down at accentric state a little, so car sheave 20 generations are vibrated.This vibration is passed to the framework of car from car sheave beam 19.That is, through the upper beam 16 that car sheave beam 19 has been installed be delivered to the vertical frame 18 that links with this upper beam 16, with the transverse arm 13 that should vertical frame 18 contact, with the support 12 of these transverse arm 13 bindings be installed on the machine base 14 between the top of support 12 etc.Therefore, the whole lift car after the vibration that car sheave 20 produces is passed to assembling causes human discomfort and sense of insecurity for the elevator user.
Lift car after the assembling is provided with the door as movable body.This can be held switching under the effect of the switching mechanism on the door machine base 14.Therefore, when car goes up and down operation, if the oscillating action that car sheave 20 and main rope engagement produce in door machine base 14, then door self might produce strong vibration with this vibration resonance.
Therefore; The present invention installs AMD23 at the bang path that comprises above-mentioned car framework of the vibration that produces from this car sheave 20; Produce phase place and the opposite vibration of vibration that produces from car sheave 20 by this AMD23, thereby suppress from the vibration of car sheave 20 generations.
This example is installed in AMD23 near the place that is provided with car sheave 20 of car sheave beam 19.That is, the mounted panel 21 that side setting and the car sheave beam 19 in car sheave beam 19 ends becomes one, with installation appliance 22 shown in Figure 2 that AMD23 is mounted thereto.
So, owing to be provided with AMD23, therefore can suppress the vibration that produces from car sheave 20 effectively near position as the car sheave 20 that vibrates the generation source.
Wherein, AMD23's is provided with the place as stated for the end side that is provided with car sheave 20 of car sheave beam 19.This place is the dead-space volume of the acute angle shape of generation between car sheave beam 19 and the upper beam 16 when the top is seen shown in Fig. 1 (a), never is used before, and this example effectively uses as AMD23 the place being set.And,, therefore bigger to vibrative inhibition effect owing to this is done near as near the car sheave 20 that vibrates the generation source.
And, the vibration that the vibration that produces from car sheave 20 produces when being mainly the groove 20a that main rope is engaged to car sheave 20, the vibration component of the Width of car sheave 20 (left and right directions of Fig. 2) is more.Therefore,, can suppress the vibration component of the Width of car sheave 20 effectively through as above-mentioned, AMD23 being arranged on integratedly the side of the car sheave beam 19 that is provided with car sheave 20, bigger to vibrative inhibition effect.
In addition, owing to can measure in advance, therefore produce the opposite AMD23 of setting quiveringly of phase place of phase place and this vibration from the vibration of car sheave 20 generations.And, because from the timing interlock of these car sheave 20 vibrative timings with the elevator operation, therefore corresponding with the run timing of elevator, ground makes AMD23 produce the opposite control unit of setting quiveringly of phase place.
If set like this, then when vibration that elevator operation, the engagement that produces main rope from car sheave 20 cause,, can offset this generation and vibrate, thereby it is suppressed through producing the phase place vibration opposite with this vibrative phase place from AMD23.
In addition, when being applied with vibration on the AMD23, also can detect this vibration, produce corresponding to the opposite vibration of the phase place of the vibration that is applied in AMD23 one side.
So, the damping of vibrations that utilizes AMD23 to produce, the vibration that produces because of the rope engagement that can suppress car sheave 20 is delivered to the car framework, promptly finally is delivered to the cage of lift car from car sheave beam 19, realizes solemnly silent cage.And, can effectively utilize the dead-space volume between car sheave beam and the upper beam.Thus, can obtain the equipment for inhibiting of vibration saving the space and guarantee the solemn silence property of cage.
With respect to AMD23, suchly shown in also can image pattern 2 counterweight supporting part 25 be set in bottom as the mounted panel 21 of the installing component of AMD23, with this counterweight supporting part 25 counterweight 26 is installed integratedly.This counterweight 26 is to avoid the parts of the resonance of the radio-frequency component from the vibration that car sheave 20 produces.
So, set the eigentone of car sheave beam 19, make it in the operating frequency range of AMD23 through loading counterweight 26.That is, the radio-frequency component of vibration is avoided by the resonator system of car sheave beam 19, and low-frequency component is blocked by the ACTIVE CONTROL of AMD23.Therefore, compare when only on car sheave beam 19, the AMD23 monomer being set, can improve the blocking-up performance of vibration, can further improve the solemn silence property of cage.
Though in the above-mentioned example AMD23 is installed in integratedly the end side that is provided with car sheave 20 of car sheave beam 19, the present invention is not limited thereto, also can image pattern 3 shown in that kind be arranged in the car sheave beam 19.Fig. 3 takes out and has represented car sheave beam 19 self, and this figure (a) is a birds-eye view, and this figure (b) is a front view.
As stated, car sheave beam 19 can be provided with car sheave 20 for assembling the parts of pair of right and left channel-section steel up and down abreast respectively at the both ends of its length direction rotatably.On the position near side's car sheave 20 of installing on the pair of right and left channel-section steel that is configured in the bottom that appliance 22A is installed in AMD23 such car sheave beam 19 integratedly.
Because the installation site of AMD23 also near the car sheave 20 that vibrates the generation source near conduct, therefore can suppress the vibration that car sheave beam 19 is vibrated that produces from car sheave 20 effectively at this moment.And, because AMD23 is arranged on the inside of car sheave beam 19, so need not rethink the configuration of layout and car upper articles for use, the degree of freedom of layout is high, and can improve the solemn silence property of cage.
In addition; Though above-mentioned all examples all are near the some positions in 2 car sheaves 20 of the total that is arranged at car sheave beam 19 two ends, an AMD23 to be set, AMD23 (adding up to 2) can certainly be set in position respectively near 2 car sheaves.So, the number that is provided with of AMD23 is as long as suitably select just passable according to the performance of AMD23 self or vibrative size etc.
And,, also can AMD23 be installed between car sheave beam 19 and the car framework though above-mentioned example all is that AMD23 is installed near on the car sheave beam 19 as the car sheave 20 that vibrates the generation source.
Fig. 4 representes the example of this moment.Among this embodiment AMD23 is installed near installation car sheave 20 of car sheave beam 19 and constitutes between the upper beam 16 of car framework.That is, such end sides that is provided with car sheave 20 at car sheave beam 19 is provided with support 26 shown in the image pattern 5, and the end of the installation appliance 22B of AMD23 is combined on this support 26.AMD23 is maintained at and installs in the appliance 22B, and the other end of this installation appliance 22B is installed on the upper beam 16.
Wherein, Put the beams in place 16 for the parts of car sheave beam 19 are installed; Transmitted vibration from car sheave beam 19; But between near the position the car sheave 20 in the conduct of car sheave beam 19 vibration generation source and the upper beam 16 AMD23 is set integratedly through crossbearer, can decays effectively from the vibration of car sheave beam 19 transmission to upper beam 16.
Especially because crossbearer is provided with AMD23 between 16 in the end sides of car sheave beam 19 with putting the beams in place, so can suppress the vibration of the horizontal direction of car sheave beam 19 effectively.As previously mentioned, owing to the vibration that produces from car sheave 20 mainly is to produce with the rope engagement, so the vibration component of horizontal direction is big.The vibration that therefore, can suppress this horizontal direction effectively means the inhibition effect of whole vibration big.And through adopting crossbearer in the end sides of car sheave beam 19 and the structure that AMD23 is set with putting the beams in place between 16, the installation appliance 22B of maintenance AMD23 has improved the rigidity of car sheave beam 19 ends, has also suppressed vibration in this.
So, because the vibration of the horizontal direction of car sheave beam 19 is bigger to the noise effect that the rope of car sheave 20 meshes into, therefore through making the effect of AMD23 along continuous straight runs, the effect that suppresses noise is high.And the rigidity that AMD installs appliance 22B also has the effect that the top that makes car sheave beam 19 is not easy to vibrate.Can obtain to improve the equipment for inhibiting of vibration of cage solemn silence property thus.
In addition; Also have structure for car sheave beam 19 is installed on the underbeam 17 that constitutes the car framework, will scheme in not the main rope of expression surround the car on the car sheave that is positioned at below the car, this moment as long as the employing crossbearer between the end sides of car sheave beam 19 and underbeam 17 that the structure of AMD23 is set is just passable.
Example shown in following instruction diagram 6 (a) and (b).This example is respectively at the two ends of car sheave beam 19 and constitute between a pair of transverse arm 13 of framework AMD23 is installed.That is, that kind is provided with support 27 in the bottom at car sheave beam 19 two ends shown in the image pattern 6 (b), and crossbearer ground one between this support 27 and transverse arm 13 is installed the installation appliance 22C that keeps AMD23.
Wherein, A pair of transverse arm 13 be from car sheave beam 19 through put the beams in place 16 with vertical frame 18 by the part of transmitting vibrations; Through crossbearer car sheave beam 19 near between as the end of the car sheave 20 in vibration generation source and transverse arm 13 be wholely set AMD23, can decay effectively from the transmission of vibration of 19 pairs of transverse arms 13 of car sheave beam.And through linking car sheave beam 19 and transverse arm 13, the framework whole rigidity of car improves.And, utilize the damping of vibrations of AMD23 can prevent that the vibration of car sheave beam 19 from propagating into the framework and the cage of car through transverse arm 13.
So,, the specification of the parts that constitute the car framework can be reduced, the effect of cost-cutting and lightweight etc. can be obtained through improving the framework whole rigidity of car.And, owing to utilize the vibration suppressioning effect of AMD23 can reduce the vibration of car framework and cage, so also realized the solemn silence property of car.
Though above-mentioned example is arranged on AMD23 between car sheave beam 19 and the car framework, also can AMD23 be assembled between the parts that constitute the car framework.Fig. 7 is the example of this moment, and AMD23 is installed between a pair of transverse arm 13 and door machine base 14 that constitutes the car framework.That is, will keep the two ends of the installation appliance 22D of AMD23 to be connected on a pair of transverse arm 13 and the door machine base 14, and tiltedly draw shape ground to strengthen between them through support 28.
So, link transverse arm 13 and door machine base 14 through tiltedly drawing shape ground, the rigidity of door machine base 14 improves.And, utilize the damping of vibrations of AMD23 can suppress to vibrate from transverse arm 13 propagation to a door machine base 14.
Wherein, Though generally speaking with binding transverse arms 13 and a door machine base 14 such as slant-pull structures, make it have enough intensity ground and design, link a transverse arm 13 and a door machine base 14 through as above-mentioned, passing through AMD23; Then slant-pull structure need be do not reset, the space can be saved.And, when door machine base 14 vibration, might cause door vibration, develop into noise problem, but through as above-mentioned and transverse arm 13 between AMD23 is set, can suppress the vibration of a machine base, can avoid noise problem.Thus, can obtain to improve the rigidity of car framework structure and the equipment for inhibiting of vibration of realizing car solemn silence property.
