Description
Technical field
The present invention relates to railroad track field, particularly relate to sleeper and the elastic damping rail system in a kind of railroad track field.
Background technology
Railroad track generally comprises railway roadbed (ballast track bed or ballastless bed), sleeper and rail.Railway roadbed is formed on roadbed or bridge, and sleeper laying is on railway roadbed, and rail is then arranged on sleeper.But the either sleeper of which kind of form, that current most of railways use or transverse sleeper, i.e. sleeper are the horizontal direction layings along railway or rail.There is shortcomings with not enough in this transverse sleeper: transverse sleeper is to be laid on discretely on railway roadbed, is therefore unfavorable for the distribution to the load from rail.When train passes through, affected by impact wheel load, shock loading suffered by sleeper is the biggest, easily following railway roadbed is produced and destroy, such as cause ballast aggregate pulverizing, outer shifting etc., thus deformation of rail can be caused after using for a long time, make the train of traveling vibration occur and swing, strengthen vibrating noise, and have a strong impact on operation stability and the riding comfort of train.In turn, due to train vibration and swing, the deterioration of rail conditions can be accelerated again.If railroad track deforms (being primarily referred to as deformation of rail), or concrete sleeper generation cracking etc., then needing to expend substantial amounts of manpower and materials is corrected the deformation position of track, or repairs the cracking position of concrete sleeper.It addition, also need to often the ballast aggregate pulverized or move outward be carried out maintenance.The maintenance work of railway is extremely wasted time and energy.
Along with people's raising to quality of life demand, the interference of life is also got most of the attention by vibration and the noise of urban track traffic.
Summary of the invention
The longitudinal beam type sleeper of the present invention and elastic track system are a kind of schemes proposed for solving the problems referred to above, and this sleeper is intended to reduce required maintenance activity etc., and it is in the sleeper of ordinary meaning, refer to the concept of beam.
Its mechanism and means are: (1) is by improving the distribution of train load, reduce the track deformation caused because of the train load repeated, (2) the big lateral resistance that continuous print longitudinal sleeper is provided is utilized, reduce because of the deformation caused by track lateral load, such as lateral thrust.The present invention another object is that, there is provided the railroad track that these sleepers a kind of and rail link for achieving the above object, the present invention includes longitudinally each, rail being provided below longitudinal beam along described rail, and by these longitudinal beams by the interconnective multiple connectors in interval set, and it is arranged in the elastic bearing between longitudinal beam bottom surface and basis railway roadbed bearing.
It is an object of the invention to be realized by following technology:
One longitudinal beam type sleeper system of the present invention, including longitudinal beam type sleeper and elastic damping rail system；Described longitudinal beam type sleeper is formed by the concatenation of longitudinal beam type sleeper unit one by one.Longitudinal beam type sleeper unit includes consistent with the trend of rail and is separately positioned on a pair longitudinal beam below two one steel rails, and being laterally fixed together by connector between a pair described longitudinal beam forms frame structure.It is connected by sleeper connector between the relative longitudinal beam end of adjacent longitudinal beam type sleeper unit, thus composes in series the longitudinal beam type sleeper of integral type.Elastic damping rail system includes that bearing, described longitudinal beam type sleeper are arranged on bearing, is disposed with vibration damping facility between the bottom of described longitudinal beam type sleeper and described bearing.
Longitudinal beam type sleeper, can be prefabricated in the factory by certain length, is connected with each other by longitudinally adjacent longitudinal beam at the construction field (site), it is achieved that distance orbit rigidity uniform continuous orbit structure, and this longeron and rail are longitudinally continuous location, forms composite track.Owing to longeron can be prefabricated in the factory, greatly enhance track laying speed.Owing to being longitudinally continuous laying longitudinal beam type sleeper along rail direction, its pillow is lower arranges vibration damping facility, thus supports longitudinal beam type sleeper and elastic track system, makes the wave transformation of ground vibrations, rolling noise and rail reduce.Owing to arranging support rail boss at longeron upper surface, to meet the vertical dimension minimum requirement at the bottom of rail pipeline distance from top Rail, can effectively make rail and cross insulation between rail pipeline, having carried more convenience to maintenance and maintenance.
By using at the beam structure being parallel in orbital direction, the vibration damping facility under the continuous rail pad of supporting rail continuously and longeron is set, it is possible to reduce ground vibrations, rolling noise and rail wave transformation.The track structure of longitudinal sleeper, by improving track longitudinal rigidity and the special vibration-proof structure arranged under longitudinal sleeper, reduces vibration and the noise impact on passenger inside the vehicle to greatest extent, improves the ride quality of passenger.The requirement of different vibration damping ranks can be met, to adapt to different location difference requirement by the change flexibly mounted rigidity of vibration damping facility and form.
As it has been described above, use the longitudinal sleeper of the present invention, owing to have employed the structure at the longitudinally positioned longitudinal beam of rail, track bending resistance rigidity reinforced, the distribution of train load is improved, thus reduces by the track deformation caused by reloading, reduces maintenance activity amount.Additionally, due to longitudinal beam increases lateral resistance, vertical track irregularly reduces, and therefore decreases maintenance activity amount.And then, due to along longitudinally using the mode being similar to long welded rails that continuous print longitudinal beam will be kept to interconnect, it is therefore prevented that longitudinal beam end rails is damaged.And by arranging rail pad continuously, decrease ground vibrations, rolling noise and the wave transformation of track.
By mentioned above, the longitudinal sleeper system of the present invention mainly includes but not limited to these advantages.
Need especially it is emphasised that; in the different embodiments of the present invention; each feature above-mentioned can be used alone; can also carry out using (as long as this combination is possible or reconcilable) by the most feasible compound mode, within thus obtained all of embodiment falls within protection scope of the present invention.In order to avoid repeating, various possible compound modes are no longer described in detail by the present invention.
