Description
Technical field
The utility model relates to a kind of cushion blocking of field of track traffic, especially a kind of railway roadbed elastic damping pad for ballast bed structure vibration and noise reducing.
Background technology
In recent years, the Rail Transit Construction Development of China is rapid, and bring many facilities to the productive life of people, meanwhile, the vibration noise problem that disturbs residents produced in rail vehicle operation process also becomes increasingly conspicuous.For solving the vibration noise problem in rail vehicle operation process, cushion vibration-damping ballast technology is widely applied.Wherein, cushion becomes the key of this type of technology damping property quality.In existing cushion, apply more, effect is preferably the patent No. a kind of vibration-absorbing noise-reduction pad disclosed in the Chinese patent of 201020109284.5, specifically comprise a substrate and multiple conic convex, wherein conic convex is arranged in substrate by array-like, substrate order is by damping layer, rubber coating, base fabric, rubber coating, base fabric, rubber coating and covering layer composition, also bonding jumper is provided with in covering layer, its " hot strength utilizing rubber fabulous and tear resistance, abrasion resistance, against natural aging corrosion resistance is as the leading material of pad, utilize the resistance to shock that conic convex is good simultaneously, good ventilating drainage effect is had between its space, make can not produce coagulation bottom bed course, efficient isolation can be carried out to the structural vibration in high-speed railway and similar application and noise after application, thus reduce resistance and wearing and tearing ".But in use, also there are some problems in this vibration-absorbing noise-reduction pad, be in particular in: on the one hand, this pad is by the space of conic convex surrounding, the souring of ventilating drainage is utilized to take away foreign matter, prevent bed course congregate or produce coagulation, but when applying in subway tunnel, under water seepage of tunnel can invade pad, due to infiltration underfed, can not manually wash away again, therefore souring described in it cannot be played, sandy soil can be entrained with on the contrary, alluvial is in conic convex surrounding, and subway reaches 100 years application life, mineral matter in water also can slowly calcification condense in around conic convex, the elasticity of conic convex and vibration isolating effect are slowly disappeared, particularly the space of conic convex surrounding communicates with each other, a seepage point just can have influence on the performance of a slice vibration-absorbing noise-reduction pad around, this product comes from the vibration isolation of ground machine equipment and building vibration isolation the earliest, do not consider this special applications of subway, once lose efficacy, cannot change again, hidden danger is very big, insider is very worried, a kind of novel elastic pad not having above-mentioned shortcoming of urgent hope exploitation, on the other hand, the conic convex of vibration-absorbing noise-reduction pad is arranged in substrate by array-like, due to less with basic contact area, when surface of base not at ordinary times, height change cannot compensate, its local actual carrying capacity can there is marked change, compliance is poor.
In sum, the cushion of market in the urgent need to providing a kind of better adaptability, effect of vibration and noise reduction more stable.
Summary of the invention
The purpose of this utility model is to solve the problem, the railway roadbed elastic damping pad providing a kind of better adaptability, effect of vibration and noise reduction more stable.
The utility model railway roadbed elastic damping pad realizes like this, comprise substrate, substrate is provided with elastic bumps structure, elastic bumps structure comprises many carrying fins, the top of carrying fin is provided with elastic compensating deformation layer, and the sealing fin that described elastic compensating deformation layer is arranged continuously by least one edge carrying fin bearing of trend is formed.
Preferably, the height of described sealing fin is not less than 2mm, and is not more than 1/5th of carrying fin height.For keeping good elastic deformability, generally, the face rigidity of described sealing fin is not more than 1/10 of carrying fin face rigidity.
The arrangement of described elastic bumps structure can be varied, such as, in elastic bumps structure, described many carrying fins can be set parallel to each other, between adjacent carrying fin, gap is set, if desired, the enclosing closed in gap can also be set respectively at the two ends of adjacent carrying fin; Or in described many carrying fins, intersect each other between two between part carrying fin, surround multiple chamber, the cross-sectional profiles shape of chamber comprises circle, ellipse, triangle, quadrangle, pentagon, hexagon or octagon.The shape of cross section of carrying fin can be specifically the shape such as trapezoidal, square, rectangle or cydariform.In addition, in order to reduce difficulty of processing, ensure sealing performance, preferably, described sealing fin is parallel to the carrying fin belonging to it.The shape of cross section of sealing fin can be specifically the shapes such as triangle, trapezoidal, square, rectangle or cydariform.
