Abstract
The invention discloses a ballastless track disengaging-resisting elastic anti-vibration cushion. The upper surface and the lower surface of a cushion body (1), the upper surface and the lower surface of the bottom of a groove (9) and the outer surface and the inner surface of the side wall of the groove (9) are respectively provided with protrusions (6). The rigidity of the front portion (1a) and the rear portion (1c) of the cushion body (1) in the longitudinal direction is smaller than the rigidity of the middle (1b) of the cushion body (1). The cross section of the periphery of the cushion body (1) is in a fork finger shape (5) with inward notches. According to the ballastless track disengaging-resisting elastic anti-vibration cushion, impact of train loads on the cushion can be effectively buffered, damage to the elastic anti-vibration cushion due to partial disengaging between a roadbed plate and a bed plate is avoided, safe traveling of a high-speed train is better ensured, and the ballastless track disengaging-resisting elastic anti-vibration cushion is long in service life, strong in vibration and noise reduction performance, meanwhile saved in rubber use quantity, low in manufacturing cost and particularly suitable for being used in a double-block type ballastless track on a plate joist bridge with uneven rigidity and a route with poor roadbed conditions.
Description
Technical field
The present invention relates to the elastic damping cushion of High-speed Passenger Dedicated Lines double-block type ballastless track.
Background technology
China carries out personal rapid transit special line railway network construction on a large scale, high-speed railway build the inexorable trend and reality need that become China railways System Development.In order to the safety that meets 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, thus requires that track structure must possess high ride and high stability.Non-fragment orbit has good structure constancy, stability, durability, few technical characterstic such as maintainability, economy, and thus high-speed railway is widely used abroad.
Be provided with elastic damping cushion between the road bed board of non-fragment orbit and bed plate, its Main Function fills adjustment, load power transmission, vibration and noise reducing, supports road bed board uniformly comprehensively.It can bear vertical force and horizontal force that road bed board transmits and pass to bed plate and stopping means, dispersion train load.Double block type ballastless rail elastic damping cushion there is the groove with the groove of bed plate and road bed board bottom protrusion adaptation, to make to combine better between three.
, there is following problem in the elastic damping cushion between existing double-block ballastless track bed board and bed plate: 1, even in each position rigidity of whole bed course.And train load when just having acted on bed course and sailed out of bed course to the impact of bed course the strongest especially on the plate girder bridge that rigidity is uneven and roadbed condition poor part of path time, the leading portion of bed course and back segment rigidity is high, elasticity is inadequate, effectively can not cushion the impact of train load to bed course, easily cause road bed board and bed plate that local occurs to come to nothing, elastic damping cushion damages, and affects track structure life-span and high speed train safety.2, elastic damping cushion surrounding and bed plate and road bed board all do not carry out Seal Design and process, and rainwater, dirt etc. are easily infiltrated, and affect the application life of rubber.3, elastic damping cushion, surfacing, under load action, lateral deformation is restricted, and is unfavorable for vibration and noise reducing; Also do not save material simultaneously.
Summary of the invention
The object of the invention is the deficiency overcoming existing double-block type ballastless track elastic damping cushion, a kind of non-fragment orbit disengaging-resistinelastic elastic anti-vibration cushion is provided, this kind of vibration damping bed course effectively can cushion the impact of train load to bed course, avoid road bed board and bed plate that local occurs to come to nothing, elastic damping cushion damages, and better ensures high speed train safety; And the long service life of elastic damping cushion, vibration and noise reducing performance is strong; Save rubber consumption, cost of manufacture is low simultaneously.Be particularly useful on the uneven plate girder bridge of rigidity and double-block type ballastless track on circuit that roadbed condition is poor uses.
The present invention realizes its goal of the invention, and the technical scheme of employing is: a kind of non-fragment orbit disengaging-resistinelastic elastic anti-vibration cushion, is installed between road bed board and bed plate, and comprise the bed course body mated with road bed board, bed plate, the groove on 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; Bed course body is less than the rigidity at middle part in the rigidity of the front and rear of longitudinal direction; The cross section of bed course body surrounding is the inside interdigitated of breach.
Compared with prior art, the invention has the beneficial effects as follows:
One, the rigidity in the middle part of bed course can be good at greatly playing support, load, intermal force, simultaneously little, the good springiness of the rigidity of bed course front and rear, effectively can cushion the impact to bed course when train load has just acted on bed course and sailed out of bed course, avoid road bed board and bed plate that local occurs to come to nothing, elastic damping cushion damages, ensure track structure life-span and high speed train safety, be particularly useful for part of path poor with roadbed condition on the uneven plate girder bridge of rigidity and use.
Two, the cross section of bed course body surrounding is the inside interdigitated of breach, the interdigitated lateral surface sealing that breach is inside, upper and lower surface has elasticity energy and road bed board and bed plate and fits tightly, be aided with stickup again, good hermetically-sealed construction can be formed, the infiltration of effective prevention rainwater and dirt, extends the application life of rubber, further increases the application life of whole elastic damping cushion.
Three, the projection that arranges 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, lateral deformation can occur under load action, its effect of vibration and noise reduction is good; Also save the consumption of rubber simultaneously, lower manufacturing cost.
Above-mentioned bed course body is provided with multiple through hole.Like this, air-blowing between bed course and concrete bed plate can be prevented, ensure its good vibration and noise reducing further, load intermal force.
Above-mentioned bed course body bed course body, at the area of the front and rear of longitudinal direction, is equally 1/4 of whole bed course body.
Projection on above-mentioned bed course body is that six prisms are protruding.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the plan structure schematic diagram of the embodiment of the present invention.
Fig. 2 is that the embodiment of the present invention is installed on the cross-sectional view after between road bed board and bed plate.
