The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to Fig. 1-3, by the utility model is provided Rubber shock-absorbing pad 10, this Rubber shock-absorbing pad 10 is arranged on below the rail of subway or light rail, vibration and noise in the time of can effectively reducing train operation, improve the safety of rail and train, reduce the incidence of fault as far as possible.Particularly, referring to Fig. 1, this Rubber shock-absorbing pad 10 comprises rubber substrate combination layer 1 and is located at the rubber damping layer 2 of being arranged by array successively by the high-intensity damper portion 21 of several endurances on rubber substrate combination layer 1.In the present embodiment, this damper portion 21 is by rectangular array, and certainly, this damper portion 21 not only can be passed through rectangular array, can also be the different array arrangements such as annular array.The bottom of this damper portion 21 is rounded, along the end face of rubber substrate combination layer 1, raises up and forms hemispherical structure.This protruding chondritic 21 makes Rubber shock-absorbing pad 10 can bear sizable pressure, thereby can play the effect of buffering.The radius of curvature of these damper portion 21 hemispherical structures is 21～181mm.This radius is less, and the rigidity of its damper portion 21 is also larger, and radius is larger, and the rigidity of its damper portion 21 is also less.Therefore the size of this diameter will be according to the applied different subway of this Rubber shock-absorbing pad 10 or its weight carrying of light rail.And the height of the hemispherical structure spherical crown of this damper portion 21 is 18mm.And this damper portion 21 adopted can the high-intensity NR rubber of endurance (basic chemical composition is cis-polyisoprene), this NR rubber has advantages of that good springiness, intensity are high, good combination property, can assist with fatigue proof preventing aging system, the frequency of the adjustment induction vibration by hardness level, to optimize the effect of damping.And Rubber shock-absorbing pad 10 provided by the utility model has good mechanical property, anti-aging, corrosion resistance, shock resistance, running resistance in the time of can reducing train driving, reduce wear, noise and vibrations that obviously the train of minimizing subway and light rail produces in running, make train operation safer, steady, thereby guaranteed the transportation safety of subway and light rail.
Further, referring to Fig. 1 and Fig. 2, in rubber damping layer 2, between adjacent damper portion 21, form the passage 22 that can be beneficial to ventilating drainage.The width of this passage 22 is 40～80mm.The passage 22 forming between adjacent damper portion 21 has even high ventilation, drainage effect, make on Rubber shock-absorbing pad 10, to be not easy to pile up the residual condensation product on rail, thereby guarantee the normal use of Rubber shock-absorbing pad 10, extend its application life, reach damping efficiently and soundproof effect.
Further, referring to Fig. 3, this rubber substrate combination layer 1 comprises rubber-based bottom 11, the first braid 12, channel rubber 13, the second braid 14 and rubber levelling blanket 15 from the bottom to top successively.This rubber-based bottom 11 is usingd NR (natural rubber) and SBR (butadiene-styrene rubber) as substrate, on the basis of the good NR of fatigue performance (natural rubber), bring the SBR (butadiene-styrene rubber) of rigid radical into, because SBR (butadiene-styrene rubber) has advantages of wear-resisting, heat-resisting, ageing-resistant and curingprocess rate is excellent, make it as the basalis of Rubber shock-absorbing pad 10 provided by the utility model, to play better the effect of bradyseism and noise abatement, can improve the abrasion resistance of Rubber shock-absorbing pad 10 simultaneously.And channel rubber 13 has adopted neoprene, because it has good physical and mechanical properties, higher hot strength, expansion and contraction and oil resistant, heat-resisting, resistance to combustion, resistance to daylight, feature that cementability is good.Can be with the bond strength of the first braid 12 and the second braid 14 more than 10N/mm through processing by channel rubber 13.And rubber levelling blanket 15 adopts the quality of rubber materials the same with rubber damping layer 2 so that this rubber levelling blanket 15 can with the one-body molded making of rubber damping layer 2.Meanwhile, rubber-based bottom 11 provided by the utility model and the first braid 12 and the second braid 14 are woven into square-grid structure by the mylar of EP200/80.This mylar is a kind of macromolecular fibre cloth of air-and water-permeable, its unique permeability has guaranteed the water-proof breathable properties of rubber-based bottom 11 and channel rubber 13 and rubber levelling blanket 15, its steam forming due to variations in temperature can be accessed timely discharges, and the adhesion stress between itself and rubber-based bottom 11 and channel rubber 13 and rubber levelling blanket 15 can't be subject to the impact of steam, thereby has guaranteed water resistance and the application life of Rubber shock-absorbing pad 10.
And the thickness that the thickness that the thickness of the rubber-based bottom 11 of rubber substrate combination layer 1 provided by the utility model is 2.2mm, channel rubber 13 is 4mm, rubber levelling blanket 15 is 2mm, the thickness of the first braid and the second braid is 0.3mm.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
