Description
Technical field
The utility model relates to a kind of vibration damping road pad, relates in particular to a kind of vibration damping road pad that is applied to high-speed railway.
Background technology
In the railway construction of China, the importance of high-speed railway is increasing, vibration that produces in the time of must solving vehicle move fast in the construction of high-speed railway and noise are to the influence aspect operation and the railway roadbed, otherwise will shorten greatly its application life, the probability that is broken down also improves greatly, for overcoming the interference and the infringement of vibrating noise and vehicle operating firm to railway roadbed, the effectively technology and the product of vibration and noise reducing just must be arranged, the safety of moving with the guarantee circuit with reach desirable speed.
And in conventional railway is built, generally use under the rail yielding rubber backing plate to carry out vibration damping and will make an uproar, this rubber mat plate can not be with the railway coupling of high-speed cruising, can't solve rail vibration and noise problem under high speed, the applicant works out the vibration damping road pad of the vibration and noise reducing of high-speed railway through long term studies and test.
Summary of the invention
The purpose of this utility model is to provide a kind of vibration damping road pad, and it can solve rail vibration and noise problem in the high-speed railway, improves the application life of high-speed railway and reduces fault rate.
For achieving the above object, the utility model discloses a kind of vibration damping road pad, it is characterized in that this vibration damping road pad comprises:
One substrate, this substrate order is made up of damping layer, rubber coating, base fabric, rubber coating, interlayer, rubber coating, base fabric, rubber coating and covering layer;
A plurality ofly be formed on suprabasil conic convex, described conic convex is formed on the damping layer of substrate.
Wherein, has bonding jumper in the covering layer.
Wherein, conic convex is arranged in the substrate by array-like.
Wherein, the tapering of conic convex is 48 degree.
Wherein, tectal thickness is 1.7mm, and the thickness of rubber coating is 0.3mm, and the thickness of base fabric is 1mm; Thickness of interlayer is 3.5mm; Damping layer thickness is 3.5mm.
Wherein, the spacing between the conic convex is 65mm.
Wherein, the height of conic convex is 22mm, and end circular diameter is 50mm, and outside diameter circle is 12mm.
Pass through said structure, the utility model utilizes the fabulous hot strength of rubber and tear resistance, abrasion resistance, the anti-natural aging corrosion resistance leading material as the road pad, in its pad, be aided with nine levels and unit altogether, thereby the vibration and the noise that reduce the vehicle operating generation improve the stability that roadbed is in operation, between its space good ventilation is arranged simultaneously, drainage, make the bed course bottom can not produce coagulation, this vibration damping road pad can be carried out efficient the isolation to structural vibration and noise, reduces the resistance and the wearing and tearing of rail assembly.
Detailed content of the present utility model can obtain by explanation described later and institute's accompanying drawing.

Fig. 2: vertical view of the present utility model.
Fig. 3: the utility model is applied to the schematic diagram of high-speed railway.
Fig. 4: the sectional view of the utility model substrate.
The specific embodiment
See also Fig. 1, shown in Figure 2, vibration damping of the present utility model road pad is formed by substrate and suprabasil conic convex, by being installed in (referring to Fig. 3) under the rail, this road pad can carry out vibration damping and noise reduction effectively, accompanying drawing 4 demonstrates the concrete formation of substrate, this substrate order is by damping layer 10, rubber coating 9, base fabric 8, rubber coating 7, interlayer 6, rubber coating 5, base fabric 4, rubber coating 3 and covering layer 2 are formed, has bonding jumper 1 in the covering layer, can utilize this bonding jumper 1 to connect to make the more vibration damping road pad of length and width degree and length, for example, be the bonding jumper between 1 meter the vibration damping road pad by two width, thereby can form 2 meters wide vibration damping road pad; Simultaneously, a plurality of conic convex are formed on the damping layer 10 of substrate, utilize the odd-shaped cross section of conic convex, bear the better effects if of pressure, it compares cylindrical projection, have better vibration damping and noise reduction, and because the gap between the conic convex, water or other liquid can waltz through this cushion blocking and utilize such as the drainage system of gutter and water pump and remove and flow, can not be deposited in influences its performance under the pad, and can design size at regular intervals according to different road conditions and requirement, with the tapered conic convex of different size, preferred conic convex is arranged in the substrate (as accompanying drawing 1 by array-like, 2, shown in 3), it can be selected fully as the case may be, its tapering can from the 30-60 degree all can, be preferably 48 the degree, the space is that 10mm-100mm all can, be preferably 65mm, its height also is an acceptable from 10mm-100mm, and other selection is determined fully according to circumstances, is preferably highly to be 22mm, end circular diameter is 50mm, and outside diameter circle is 12mm.
Wherein, tectal thickness is 1.7mm, and the thickness of rubber coating is 0.3mm, and the thickness of base fabric is 1mm; Thickness of interlayer is 3.5mm, and damping layer thickness is 3.5mm, and wherein base fabric has improved the hot strength and the flexural strength of road pad, and the life-span of pad is improved.
Aspect material, rubber coating, covering layer, interlayer, damping layer all can adopt rubber to make, and are preferably neoprene and make, and the base fabric material is preferably EP200 or EE200 and not as limit.
Basal layers such as can being used for high-speed railway, city underground, urban light rail, bridge, tunnel, highway, stadium and interior of building is paid somebody's debt and expected repayment later in vibration damping of the present utility model road, can alleviate structureborne noise and structural vibration, thereby prolong the application life of agent structure, reduce the security performance of maintenance cost and raising agent structure, simultaneously can satisfy the requirement of people to high-quality life, make it avoid the influence that high noisy produces, for the high-quality life of people requires to provide guarantee.And pass through the just difference of physical dimension of centrum, and the vibration and the noise that can reduce the vehicle operating generation improve the stability that roadbed is in operation, and between its space good ventilation are arranged simultaneously, and drainage makes the bottom of pad can not produce coagulation.
