Abstract

The utility model relates to railway track, in particular a silencing connection track. Butt joint faces of rails are connected via joggled joint on non-right angle plane, and space is left between butt joint faces. Compared with conventional track, the silencing connection track has obvious advantages that only the track connection structure is improved, requirement to material quality is low, and the manufacturing cost is low, joggled joint on non-right angle plane is employed, and space is left between joggled joint faces, thereby the silencing connection track is completely adapted to expansion and contraction law and overcomes shortages of track protrusion. Interval between joggled joint faces is more than double of interval between convention track butt joint, and thereby the silencing connection track is adapted for various areas. The joggled joint mode saves a technical procedure of track connection weld, manual power, material and financial resources of projects are saved. When wheels run over, the rails are smooth and do not generate noise, and trains operate stably.

Description

The sound-absorptive connector track

Technical field:

The utility model relates to traffic track.

Background technology:

Traditional rails adopts right angle one plane dock joint to connect, and there are three aspect drawbacks in this kind rail:

One: when vehicle ground the track right-angle plane, easily produce big noise, and influence the vehicle balance movement.

Its two: occur for avoiding big noise, need drop into a large amount of manpower, material resources and financial resources in the industry the rail joint place is welded, make track in aggregates as far as possible, but have to be limited by the rule of expanding with heat and contract with cold, cause track protuberance, not only influenced use but also uneconomical, bring hidden danger.

Its three: be the adaptation rule of expanding with heat and contract with cold, many traditionally on the track material research with improve, significantly promoted the cost of production of track virtually.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of sound-absorptive connector track is provided, and is simple in structure, effectively overcomes and expands with heat and contract with cold, and vehicle operating is steady, and cost is low.

The technical scheme that the utility model is adopted for achieving the above object is: sound-absorptive connector track, track bond face are a non-right-angle plane joggle, and be gapped between the interface.

Described track bond face is the inclined-plane joggle, to a minute double inclined plane joggle, square tenon joint type joggle, face dovetail type joggle, dovetail type joggle or two dovetail type joggle directly for a short time.

The utility model is compared with conventional rails has significant advantage:

One: only improve the rail joint structure, low to the material requirement, cost of production is low.

Its two: adopt a non-right-angle plane joggle, gapped between the joggle face, adapt to the rule of expanding with heat and contract with cold fully, overcome track and swell not enough problem.Gap between the joggle face will be twice above than the gap amplitude between the conventional rails butt joint, be suitable for various areas.

Three, joggle mode is saved the rail joint welding schedule, saves engineering human and material resources and financial resources.

Its four: wheel grinds out-of-date, and track is smooth can not to produce noise, and vehicle operating is steady.
