Abstract
The utility model relates to a vibration absorbing device for stay cables, which is composed of an inner eccentric vibration absorbing ring 3, an outer eccentric vibration absorbing ring 2, a front pressing plate 7, a back pressing plate 5 and a bolt 4. The inner eccentric vibration absorbing ring is coordinated with the outer eccentric vibration absorbing ring in a rotary mode. The front pressing plate is tightly attached at one end of the inner eccentric vibration absorbing ring 3, and the back pressing plate 5 is positioned at the other end of the outer eccentric vibration absorbing ring 2 opposites to the inner eccentric vibration absorbing ring 3. The bolt penetrates through the front pressing plate 7, the outer eccentric vibration absorbing ring 2 and the back pressing plate 5, and connects the inner eccentric vibration absorbing ring and the outer eccentric vibration absorbing ring into a whole. The eccentricity e between the inner eccentric vibration absorbing ring 3 and the outer eccentric vibration absorbing ring 2 is in a range from 0 mm to 80 mm. The rotary fit surfaces of the inner eccentric vibration absorbing ring and the outer eccentric vibration absorbing ring are respectively provided with tapers which are same in size but opposite in directions. The vibration absorbing device has the advantages of strong eccentric capability for adapting the stay cables and favorable vibration absorbing effect.
Description
The utility model relates to a kind of suspension cable parts, particularly a kind of suspension cable vibration absorber.
Vibration absorber is one of vitals of suspension cable, and it can suppress the Suo Zhendong that suspension cable causes because of extraneous factor (as wind, rain etc.) effectively, and vibration absorber generally is installed in the embedded steel tube exit on the bridge floor (or bridge tower).Always there is site error to a certain degree in embedded steel tube because of the reason of design or construction, causes suspension cable axis and embedded steel tube axis decentraction, influences the installation of vibration absorber, also causes the drag-line unbalance loading easily.The vibration absorber that uses as far back as suspension cable is a uniform thickness rubber ring, does not have to adapt to eccentric function.Though adopted later band to proofread and correct the vibration absorber of pipe, can adapt to the off-centre of drag-line to a certain extent.To take up room but proofread and correct pipe, reduce the thickness of vibration isolation rubber circle, reduce effectiveness in vibration suppression.
The strong suspension cable vibration absorber of eccentric ability that the purpose of this utility model is to provide a kind of good damping result, adapts to suspension cable.
For reaching above-mentioned purpose, the suspension cable vibration absorber of the utility model is made up of inside and outside eccentric damping ring, forward and backward pressing plate, bolt, rotation cooperates between the inside and outside eccentric damping ring, front pressuring plate is close to interior eccentric damping ring one end, rear fender is positioned at the outer eccentric damping ring other end on the other side, bolt passes front pressuring plate, outer eccentric damping ring, rear fender, and inside and outside eccentric damping ring is fused.
Eccentric damping ring rotates with outer eccentric damping ring in described respectively the tapering that size is identical, direction is opposite on the fitting face, certainly, also can not have.
Owing to adopt said structure, the utlity model has the strong advantage of eccentric ability of good damping result, adaptation suspension cable.The suspension cable vibration absorber of the utility model adopts two eccentric damping rings, by the mutual rotation of these two damping rings, make the periphery of drag-line that rubber damping circle parcel all be arranged, thereby effectively with the absorption of vibrations of all directions, reach the vibration damping purpose, realize fitting partially simultaneously suspension cable.In addition, vibration absorber is connected by cord clip with drag-line, prevents that loosening slippage causes vibration damping to lose efficacy to vibration absorber because of vibration causes, assurance obtains the favorable damping effect.
Below, the architectural feature to the suspension cable vibration absorber of the utility model is described further in conjunction with the accompanying drawings and embodiments:
Fig. 1: the suspension cable damping device structure of the utility model and install and use view.
Embodiment:
A kind of suspension cable vibration absorber.As shown in the figure, this device is made up of interior eccentric damping ring 3, outer eccentric damping ring 2, front pressuring plate 7, rear fender 5, bolt 4, rotation cooperates between the inside and outside eccentric damping ring 3,2, front pressuring plate 7 is close to interior eccentric damping ring 3 one ends, rear fender 5 is positioned at outer eccentric damping ring 2 other ends on the other side, and bolt 4 passes front pressuring plate 7, outer eccentric damping ring 2, rear fender 5, inside and outside eccentric damping ring 3,2 is fused.
On eccentric damping ring 3 and the outer eccentric damping ring 2 rotation fitting faces tapering that size is identical, direction is opposite is arranged respectively in described, taper value =2～6 °, certain, can not have yet.
According to varying in size of drag-line external diameter and pre-pipe laying interior diameter, the size of the eccentric distance e of the inside and outside eccentric damping ring of this vibration absorber changes between 0～80mm.
As a kind of conversion of the present utility model, the front pressuring plate 7 of this vibration absorber also is connected with a cord clip 8 that is enclosed within on the drag-line 6 by bolt 9.
During use, outer eccentric damping ring 2, interior eccentric damping ring 3 are packed in the pre-pipe laying 1 successively, after rotation mixes up the position mutually, tighting a bolt 4 compresses front pressuring plate 7 and rear fender 5, makes the vibration absorber distending, is close to pre-pipe laying and drag-line 6, tighten up cord clip 8, it is tightly bound round on drag-line 6, by bolt 9 vibration absorber is connected with cord clip 8, the restriction vibration absorber moves axially along drag-line.
