Description
The utility model relates to track accessories, more clearly says so to be added between rail and the concrete sleeper to increase the Composite under rail suction plate of track elasticity.
China railways adopts sleeper the earliest, adopts concrete sleeper afterwards.Because concrete sleeper rigidity is big, poor flexibility, just between rail and concrete sleeper, fill up one deck rubber mat plate with vibration damping.But, along with domestic railway at a high speed with the development of heavily loaded direction, the particularly impact aggravation that causes of rail joint position causes rail, wheel, vehicle, goods damage and concrete crosstie fracture between the wheel track, the ballast aggregate efflorescence has reduced safety, comfortableness and the reliability of vehicle.The ZL93232580.7 patent disclosure a kind of compound sleeper pad technology, it has improved the anti-seismic performance of concrete sleeper greatly, has reduced the damage of rail, wheel, vehicle.But, reach more and more higher in view of domestic to railway high speed, speed-raising to the requirement of safety and passenger vehicle comfortableness, the application of city railway vehicle is day by day popularized, and is also just more and more higher to performance demands such as the damping of railway railway rail pad, noise reduction, application life, creep resistants.
The purpose of this utility model, be to overcome above-mentioned shortcoming and defect, according to domestic more and more higher requirement to railway transportation high speed, heavy duty, a kind of good damping performance that has is provided, higher application life, low noise, low cost, be applicable to the track of different rail types such as railway, urban track traffic, different installing and locating modes, thereby can reduce the Composite under rail suction plate of car, road, people, goods damage mistake greatly.
In order to achieve the above object, the utility model is made of with the metal system elastic body that is embedded in the rubber tile middle part the rubber tile of trough of belt.Its cross section of groove on the rubber tile is a V-arrangement or parabola shaped.The central part upper and lower surface of rubber tile all has circular groove.V-shaped groove is in order to make that the deformation rate of each aspect equates under different compressive strain states, to prolong application life of the present utility model, because rubber can reduce at double in the following life-span of large deformation with approximate parabola shaped groove.The circular groove of rubber tile central part has two effects.The one, eliminate the stress of central part and concentrate.Because the central part deformation rate is big than the edge, stress is concentrated naturally.The 2nd, can eliminate the temperature Centralized of central part.Circular groove can be the excessive temperature of the central part guiding outside.And stress is concentrated and the elimination of temperature Centralized all will prolong application life of the present utility model greatly.Form cavity in the middle of the upper and lower surface circular groove makes, compressed air during distortion is with damping noise reduction.
Groove on the rubber tile can also have two kinds of vat and sulculuses, and is spaced apart.At used load hour, vat and sulculus all participate in distortion.Thereby distortion is big, and good springiness is to improve damping property and the comfortableness that axle weighs less speed car.And the not too high comparatively speaking but heavy very big rolling stock of axle of speed by the time because action is firmly very big, distortion at this moment is corresponding, and this is littler.Otherwise too big distortion causes the fracture damage of rail, concrete crosstie easily.At this moment sulculus has been compressed to fill up no longer and has participated in distortion, even also rigidity increases, thereby avoided the heavy very big train of axle by the time fracture damage.This is a kind of design that becomes rigidity.
Metal system rigid body can be a metal flat partition board, has locating hole on it.According to not co-orbital needs, can in rubber tile, bury this flat partition board underground, replace disk spring and wearing plate.Flat partition board coating adhesive and rubber tile sulfuration bond together.The rubber that locating hole makes flat partition board vulcanize back and upper and lower surface is unified into by the hole and is one, has strengthened the reliability that flat partition board and rubber tile are connected greatly.This compound backing plate (structure) can improve damping performance, plays double-deck filter action.
Four jiaos of places, the two ends of rubber tile can have a projection locating piece, also can have a wing plate locating piece.Preceding a kind of structure is a waist shape, and the polarization of projection is good, and has reduced raw materials consumption.A kind of location structure in back is used for and W shape fastener location by four wing plates, accurately firmly.
Metal system elastic body can be a metal disk spring, cushions an insulation wearing plate that with cementing agent itself and rubber tile is bondd and sulfide again by the alignment pin location that has on the rubber tile below the disk spring.The insulation wearing plate is made by glass fibre reinforced nylon material or the high non-metal insulating material of other compressive strength.Disk spring protrudes the last plane of rubber tile together with the boss on the rubber tile that it is buried underground.Because rubber tile central authorities upper and lower surface has circular groove, form a chamber film.This chamber film makes when disk spring is out of shape that air is compressed in the chamber, thereby plays the effect of damping, noise reduction.The insulation wearing plate can improve abrasion resistance, prolongs the application life of Composite under rail suction plate.Can also insulate, guarantee unimpeded by the electric wiring of track.Effect was best when glass fibre reinforced nylon was made.Disk spring then can improve elasticity greatly, and supporting capacity is big, the fatigue resistance height.
The last plane that disk spring exceeds rubber tile forms a boss together with the rubber that it is buried underground.After rail fell and adds fastener and withhold, the overwhelming majority of toe load of fastening was born by disk spring and is out of shape like this.The buckle press of small part is born by rubber in addition.This just make large-area rubber under normal conditions (have withhold ， Dan No have train to pass through) only bear very that the buckle press of fraction is unlikely to take place creep, also kept the stability of rail simultaneously.Thisly subtract the application life that the creep structure has prolonged backing plate greatly.Otherwise for a long time under compressive state, rubber can creep and then reduction of service life and losing efficacy.
Four jiaos at the two ends of rubber tile places equally also can be for having projection locating piece or wing plate locating piece.The former is similarly waist shape, has good positioning and cost is low.The latter with
Shape fastener location, accurately firmly.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of endurance compression, and thermal oxidation resistance is aging, and shock-absorbing performance is good, and noise reduction is obvious, and prolong application life greatly, and cost is low, the Composite under rail suction plate that the ratio of performance to price is big.It can satisfy the requirement of domestic railway high speed, heavy duty, reduces track, wheel, vehicle, goods and personnel's damage greatly, reduces concrete crosstie fracture and ballast aggregate efflorescence, improves comfortableness, safety and reliability.Compare in the past, prolonged many its application life.It can be widely used in 50,60, in the gapless track of 75kg/m rail, short path road, various concrete sleeper track and city underground, overhead railway, the light railway.
