Abstract
The utility model discloses an anti-disengaging damping pad layer of a ballastless track. Protrusions (6) are arranged on the upper surface and the lower surface of a pad layer body (1) of the pad layer, the upper surfaces and the lower surfaces of the bottom of grooves (9) and the outer surfaces and the inner surfaces of the side walls of the grooves (9). The rigidity of the front part (1a) and the rigidity of the rear part (1c) of the pad layer body (1) in the longitudinal direction are smaller than that of the middle part (1b). The cross sections on the periphery of the pad layer body (1) are in an interdigital shape (5) with inward notches. The damping pad layer can effectively buffer the impact on the pad layer caused by loads of a train, avoid that a roadbed slab and a bed plate are disengaged partially and the elastic damping pad layer is damaged, and better ensure running safety of the high-speed train; the service life of the elastic damping pad layer is long, and damping performance and noise reducing performance are high; the use amount of rubber is saved, and manufacturing cost is low. The anti-disengaging damping pad layer of the ballastless track is particularly applicable to plate girder bridges uneven in rigidity and double-block ballastless tracks on lines with poor roadbed conditions.
Description
Technical field
The utility model relates to the elastic damping cushion that the High-speed Passenger Dedicated Lines double-block type ballastless track is used.
Background technology
China is carrying out personal rapid transit special line railway network construction on a large scale, the inexorable trend that the building of high-speed railway becomes the China railways System Development and reality needs.For the safety of satisfying the Line for Passenger Transportation train operation and the comfortableness of riding, rail track must have the performance of continuous, smooth-going, stable, durable and few maintenance, thereby requires track structure must possess high ride and high stability.Non-fragment orbit has the technical characterstics such as good structure constancy, stability, durability, few maintainability, economy, thereby high-speed railway is widely used abroad.
Between the road bed board of non-fragment orbit and the bed plate elastic damping cushion is installed, its Main Function is to fill adjustment, load power transmission, vibration and noise reducing, supports uniformly the road bed board comprehensively.It can bear vertical force and the horizontal force that bed board transmits and pass to bed plate and stopping means, disperses train load.The groove adaptive with the groove of bed plate and road bed board bottom protrusion arranged on the double block type ballastless rail elastic damping cushion so that between the three in conjunction with better.
There is following problem in elastic damping cushion between existing double-block ballastless track bed board and the bed plate: 1, each the position rigidity at whole bed course is even.And train load has just acted on bed course and the strongest especially on the inhomogeneous plate girder bridge of rigidity and during the relatively poor part of path of roadbed condition to the impact of bed course when sailing out of bed course, the leading portion of bed course and back segment rigidity is high, elasticity is inadequate, can not effectively cushion train load to the impact of bed course, easily causing bed board and bed plate that the part occurs comes to nothing, elastic damping cushion damages, and affects track structure life-span and high speed train safety.2, all do not carry out Seal Design and processing with bed plate and road bed board around the elastic damping cushion, rainwater, dirt etc. are easily infiltrated, and affect the application life of rubber.3, elastic damping cushion, surfacing, laterally distortion is restricted under load action, is unfavorable for vibration and noise reducing; Do not save material simultaneously yet.
The utility model content
The purpose of this utility model is to overcome the deficiency that existing double-block type ballastless track is used elastic damping cushion, provide a kind of non-fragment orbit the anti-cushion blocking layer that comes to nothing, this kind vibration damping bed course can effectively cushion train load to the impact of bed course, avoiding bed board and bed plate that the part occurs comes to nothing, elastic damping cushion damages, and better guarantees high speed train safety; And the long service life of elastic damping cushion, the vibration and noise reducing performance is strong; Save simultaneously rubber consumption, cost of manufacture is low.Be particularly useful on the inhomogeneous plate girder bridge of rigidity and circuit that the roadbed condition is relatively poor on double-block type ballastless track use.
The utility model is realized its goal of the invention, and the technical scheme of employing is: the anti-cushion blocking layer that comes to nothing of a kind of non-fragment orbit, be installed between bed board and the bed plate, and comprise and the bed course body of road bed board, bed plate coupling, the groove on the bed course body is characterized in that:
External surface and the inner surface of the upper surface of the upper surface of described bed course body and soffit, bottom portion of groove, soffit and recess sidewall are equipped with projection; The bed course body is in the rigidity of the front and rear longitudinally rigidity less than the middle part; Cross section around the bed course body is the inside interdigitated of breach.
Compared with prior art, the beneficial effects of the utility model are:
One, the rigidity at bed course middle part can be good at greatly bringing into play support, load, intermal force, the while rigidity of bed course front and rear is little, good springiness, can cushion effectively that train load has just acted on bed course and when sailing out of bed course to the impact of bed course, avoiding bed board and bed plate that the part occurs comes to nothing, elastic damping cushion damages, guarantee track structure life-span and high speed train safety, be particularly useful for using with the relatively poor part of path of roadbed condition on the inhomogeneous plate girder bridge of rigidity.
Two, the cross section around the bed course body is the inside interdigitated of breach, the interdigitated lateral surface sealing that breach is inside, upper and lower surface has elastic energy and road bed board and bed plate and fits tightly, be aided with again stickup, can form good hermetically-sealed construction, effectively stop the infiltration of rainwater and dirt, prolong the application life of rubber, the application life of further having improved whole elastic damping cushion.
Three, lateral deformation can occur in the projection of the external surface of the upper surface of the upper surface of bed course body and soffit, bottom portion of groove, soffit and recess sidewall and inner surface setting under load action, and its effect of vibration and noise reduction is good; Also save simultaneously the consumption of rubber, lowered manufacturing cost.
Above-mentioned bed course body is provided with a plurality of through holes.Like this, can prevent air-blowing between bed course and the concrete bed plate, further guarantee the vibration and noise reducing that it is good, the load intermal force.
Above-mentioned bed course body bed course body equates to be 1/4 of whole bed course body at the area of front and rear longitudinally.
Projection on the above-mentioned bed course body is six prismatic projections.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
