Abstract

The utility model relates to a novel rail for the railway of vehicle travel, two end of which comprises concave-convex channel block that is vertical to the bottom side of rails. The gap of the novel rail in joint is distributed in different area of contact surface between the cartwheel and the rail along vehicle running direction, so the contact between the cartwheel and the rail is continuous contact or close to continuous contact, so as to weaken or eliminate impact coming from running vehicles and vibration and noise induced by the impact. The utility model has the advantages of energy saving, long service life.

Description

New type rail

The utility model is to be used for the employed rail of rail vehicle transportation.

In existing technology, be used for the rail of rail vehicle transportation, the two ends of its rail is and orthogonal plane, bottom surface.Because rail has expansion and contraction, so the length of rail changes along with the variation of the temperature at spring, summer, autumn and winter and daytime and night.When temperature was high, rail just expanded and extends; When temperature was low, rail just shrank and shortens.For fear of when the high temperature, rail is subjected to hindering the accident that the huge internal stress that produces makes that rail distortion dislocation causes because of the elongation of expanding, in design of setting up track and construction, during all with the local highest temperature rail joint place seamless be zero point.Like this, be lower than in most times of the highest temperature, just there is the slit of a determining deviation joint of two rails, again because the two ends of rail is concordant, thus when vehicle by the time wheel and rail just because the existence in slit produces interrupted the contact, thereby generation is vibrated, produce noise, increased the vehicle operating resistance, increased energy consumption, the application life of vehicle has also been shortened in wheel rim and the interrupted shock and vibration that contact generation of rail simultaneously.In existing technology, adopt the short rail of welding to make the way of long rail, eliminate the gap, eliminate the impact that bring in the gap, and the vibration and the noise that cause by impact.But, the steel rail welding complexity, maintenance is inconvenient, and long rail is to the corresponding raising that requires of roadbed and construction, thereby has limited the scope of application of long rail.

In view of the problem that exists in the above-mentioned prior art, task of the present utility model is to solve rail vehicle to be in operation, because the gap of wheel and rail junction is when being in contact with one another, and suffered impact and impact caused vibration and noise.

The method that solves is, the two ends of novel rail is made up of the concavo-convex geosynclinal block perpendicular to rail foot surface, and the concavo-convex geosynclinal block of any two ends head can coincide mutually, as shown in drawings.The shape of the concavo-convex geosynclinal block of two ends of novel rail can be made up of the projection and the groove of one or more square, trapezoidal, zigzag identical or inequality, garden arc.Also can combining by the above-mentioned concavo-convex geosynclinal block of various difformities.

The utility model, the two ends that is rail are to constitute with concavo-convex geosynclinal block, can correspondingly coincide.Adopt this structure, can be distributed in the slit at rail joint place the difference of the contact surface upper edge vehicle operating direction of wheel and rail.When vehicle operating, wheel contacts with the rail joint place, just realize Continuous Contact or be similar to Continuous Contact, thereby reach the impact that the slit of weakening or eliminating the rail joint place produces vehicle, and, reduce the vehicle operating resistance, energy conservation by vibration and noise that impact causes, improve the speed of a motor vehicle, prolong vehicle service life.

Accompanying drawing is structure of the present utility model and implements schematic diagram.

Projection 1 in the accompanying drawing between the two rails coincide with groove 2 is corresponding mutually.

Figure one is the connection diagram between rail and the rail.

Figure two is sectional drawings of steel rail ends structure.

Claims

1, a kind of rail that is used for the rail vehicle transportation is characterized in that the two ends of rail is made up of the concavo-convex geosynclinal block perpendicular to the bottom surface, and the concavo-convex geosynclinal block of steel rail ends can correspondingly coincide.

2, by the described rail of claim 1, that the two ends that it is characterized in that rail is is trapezoidal, square, zigzag or garden arc.
