Abstract
The utility model provides a vibration-absorbing backing plate with micropore/frustum structures. A plurality of symmetrical quadrilateral frustums protruding out of surfaces are formed integrally on an upper surface and a lower surface of a main body; every four adjacent frustums surround into an inverted frustum-shaped pit; the protruded frustums and the pits are staggered with each other on the upper surface and the lower surface of the main body; and a microporous layer is formed on an intermediate layer of the main body, and rises and falls along with the rising and falling of the frustums. The upper surfaces of the frustums are bearing surfaces; high elasticity can be provided through flexibility, cutting, compression and microporous deformation; and the vibration-damping backing plate has the characteristics of low stiffness, low dynamic/static stiffness ratio and excellent vibration-absorbing effect.
Description
Technical field
The utility model designs a kind of micropore/terrace with edge structural vibration reduction backing plate, relates in particular to the low rigidity shock absorption backing plate of a kind of urban track traffic vibration damping track switch special use.
Background technology
In urban track traffic, the track structure of the track structure of track switch and straight line circuit has bigger difference.The straight line circuit all uses long rail usually, and in the rail clip system, rail respectively is provided with a vibration attenuation pad down and under the iron chair, and the railway rail pad size is less, and iron chair lower bolster size is big slightly, two kinds of backing plate uniform specification, quiet rigidity unanimity.
The track structure of track switch more than the straight line portion complexity many.Vibration attenuation pad just has more than 20 kind of dimensions under every group of track switch plate, and maximum can reach 900 * 180 * 12mm
3The also comparable straight line wiring board of minimum lower bolster is bigger, is 340 * 180 * 12mm
3The employed rubber damping backing plate of past track switch almost is a kind of rigidity of a kind of dimensions, and backing plate is big more, and rigidity is high more, causes track switch circuit effectiveness in vibration suppression relatively poor.
Recently orbit Design person has released the design of a brand-new track switch track circuit, the i.e. design of vibration damping track switch.Require that vibration attenuation pad has low rigidity, low/the sound ratio of rigidity under the used plate of vibration damping track switch, effectiveness in vibration suppression improves 3 decibels at least than rubber mat plate.
As if the rigidity of vibration attenuation pad, rebound velocity are mainly decided by the structure of used material, backing plate, select for use the vibration attenuation pad of the various structures of finding so far to reach the requirement of vibration damping track switch, remain in very big difficulty.
The utility model content
The purpose of this utility model is to provide a kind of micropore/terrace with edge structural vibration reduction backing plate, because it has special sandwich structure, can make backing plate provide high screen resilience, low rigidity, low moving/quiet ratio of rigidity and the fast characteristics of elasticity resume speed by the distortion of deflection, shearing and micropore, and transverse deformation is little and even under the effect of vertical force, the deformation amplitude is big under the effect of dynamic force, can make rail support put elastification more, bring into play effectiveness in vibration suppression better.
In order to achieve the above object, the micropore that the utility model provides/terrace with edge structural vibration reduction backing plate adopts micropore/terrace with edge structure, its special type is: the upper and lower faces at body is formed with an irregular body, this irregular body is formed the upper and lower faces mutual dislocation by the prismoid shaped pit that terrace with edge shape projection and adjacent ribs platform convex piece surround.The upper surface of terrace with edge is the quadrangle of symmetry, and the basal surface of pit also is the quadrangle of symmetry, and four the adjacent terrace with edge projections in upper and lower, left and right surround a pit; Four the adjacent pits in upper and lower, left and right are round a terrace with edge projection; Adjacent terrace with edge rib--rib joins and is " ∨ " shape, angle, adjacent pit baseplane--be " ∧ " shape projection between the angle; Form a microporous layers in the middle of the body, be sandwich structure, microporous layers rises and falls with the fluctuating of terrace with edge.The upper surface of terrace with edge is a load-carrying surface, can provide elasticity by deflection, shearing, compression and micropore distortion under the effect of vertical force, unloads to form rapidly after the power and recovers
The utility model provides the rigidity of micropore/terrace with edge structural vibration reduction backing plate to change by size, the degree of depth, the gradient of terrace with edge side surface and the thickness of microporous layers of being inverted terrace with edge shape pit and the size of micropore size of the terrace with edge top surface area protruded.The macromolecular material of the enough higher modulus of energy is produced the vibration attenuation pad of low rigidity, low moving/quiet ratio of rigidity, and its characteristics are as follows:
(1) can realize that switch base plate hangs down rigidity.
(2) has low moving/quiet ratio of rigidity.
(3) microporous layers has certain sound absorption.
(4) has good effectiveness in vibration suppression.
(5) the inefficacy backing plate is recyclable utilizes again, helps environmental protection
Description of drawings
Fig. 1 is product figure of the present utility model.
Fig. 2 is a sectional drawing of the present utility model.
Fig. 3 is the partial enlarged drawing of the utility model sectional drawing.
The specific embodiment
The raw material that the utility model adopts is the material modified or macromolecule complex material of high-performance poly copolyether ester elastomer, can buy off-the-shelf from manufacturer.The utility model just is molded into goods with above-mentioned raw materials with method time processing in mould of injection foaming.This product does not have special requirement to production equipment, and known equipment gets final product.
Please, be front view of the present utility model referring to Fig. 1.As seen have the surface to be square terrace with edge on the body, four the adjacent terrace with edges in upper and lower, left and right surround an inverted terrace with edge shape pit.
Please, be sectional drawing of the present utility model referring to Fig. 2.As seen the terrace with edge of body is in body upper and lower, left and right face mutual dislocation, and a microporous layers is arranged in the middle of the body, rises and falls with the fluctuating of terrace with edge.By the size of terrace with edge upper surface, the gradient of side surface, the degree of depth and the thickness of microporous layers and the size variation of micropore of pit, can produce the vibration attenuation pad of different-stiffness.
Please referring to Fig. 3, for the layout of the utility model sectional drawing is amplified.As seen form a microporous layers in the middle of the body.
