Abstract

The utility model provides rails formed by connecting a plurality of sections of flange beams, and the connecting parts are retained with dilatation joints. The rails are characterized in that the connecting end of two adjacent sections of flange beams can inosculate with each other and present an S shape. The rails of the utility model cause wheels to be supported continuously when passing through the dilatation joints without discontinuity points, and wheels can reposefully finish the transition from one flange beam to another flange beam without generating vibration, so passengers feel comfortable on the train. In addition, the parts of the train are not easy to become loose, the frequency of examining and repairing is low, so the rails provided by the utility model facilitate the safe running of the train and improves the service life of the train.

Description

A kind of rail

Technical field

The utility model relates to a kind of rail.

Background technology

At present the rail that uses of people all is to be formed by connecting by a section i iron, and the link of adjacent two sections i iron is the I font, and promptly end face is a plane perpendicular to orbital plane.The greatest drawback of this rail is: rail is discontinuous to the support of wheel at the place, shrinkage joint of rail, directly cause the bump of wheel and rail, this not only produces huge resistance to travelling of train, also causes the loosening of train component easily, brings potential safety hazard.

The utility model content

The purpose of this utility model is to provide a kind of rail that makes wheel be subjected to continuously uninterrupted support.

This rail that the utility model provides is formed by connecting by a section i iron, and the junction leaves the shrinkage joint, it is characterized in that the S shape of link for matching of adjacent two sections i iron.

Because the utility model is made as a S shape with the link of adjacent two sections i iron, making wheel is to be subjected to support continuously through the shrinkage joint time, there is not discontinuous point, can carry out the transition to another root i iron from an i iron reposefully, can not produce vibration, the passenger can comfortablely be ridden, the component of the component of train are difficult for loosening, repair rate reduces, the application life that is very beneficial for the safe operation of train and improves train.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Specific embodiments

The utility model rail still is formed by connecting by a section i iron.

Fig. 1 shows first section i iron and second section i iron still leaves the shrinkage joint in the junction, the S shape that they can match being shaped as of link.When train to right-hand when travelling through the shrinkage joint, when being the AB line such as the contact wire of wheel and rail, the A point is positioned at the shrinkage joint, the B point is positioned at left side section i iron, this moment is by left side section i iron support wheel; When the contact wire of wheel and rail was the CD line, its C point was the S shape peak dot of right section i iron, and at this moment, a wheel part is about to enter second section i iron, and another part is still by left side section i iron support; When train moves on, when the contact wire of itself and rail was the EHG line, the E point was at the shrinkage joint, but G point, H point be on left side section and right section, and this moment, wheel was subjected to the common support of left side section and right section i iron; When the contact wire of wheel and rail was the FIJ line, the F point was at shrinkage joint place, but I point, J point be on left side section and right section i iron, and this moment, wheel still was subjected to the common support of left side section and right section i iron; When the contact wire of wheel and rail is the KL line, the K point is at the shrinkage joint, but the L point is on right i iron, and wheel begins by right section i iron independence support, steadily finish wheel thus gradually by of the transition of left side section i iron, make shockproof the travelling of train energy to right section i iron.

Claims

1, a kind of rail is formed by connecting by a section i iron, and the junction leaves the shrinkage joint, it is characterized in that the S shape of link for matching of adjacent two sections i iron.
