Abstract

The utility model relates to a rail capable of damping and preventing collision. Two end surfaces of the rail are inclined planes or concave-convex mating surfaces, inclined gaps or folded line type gaps are formed via fixing pieces when overlapping, and wheels partially contact with the gaps when a train runs. Vibration and collision are reduced, noise is decreased, the service life of the rail is prolonged, and the utility model can be used as a high-speed train rail.

Description

High-speed train rail capable of damping and preventing collision

The utility model relates to a kind of track.

Track of the prior art is generally straight section, form to be interrupted the shape slit during overlap joint, and during the train walking, wheel runs into the slit and vibrates, thereby produces noise, and the while has also been reduced the application life in road, and is unsuitable for bullet train and travels.

The purpose of this utility model provides and a kind ofly reduces vibration and prevent the bullet train track that clashes into.

The purpose of this utility model realizes that by following measure the both ends of the surface of I-shaped track 1 are the inclined-plane, track during by fixture 2 overlap joint seam the gap R-joining such as be.

An end face of I-shaped track 1 has convex rail 4, and the spill rail 3 of its other end for matching with convex rail 4, track form broken line shape slit when being overlapped by fixture 2.

The convex rail 4 of track protrudes for the track two ends are a side, and opposite side is a spill, and overlap joint forms the broken line type slit.

Narrate below in conjunction with drawings and Examples.

Fig. 1 is an angled end-face formula track.

Fig. 2 is a convex concave end face track.

Fig. 3 opens the track of convex concave end face for side.

Fig. 4 is that the AA of Fig. 1 is to view.

With reference to accompanying drawing 1,4 is embodiment of the present utility model, and the both ends of the surface of I-shaped track 1 are the inclined-plane, track during by fixture 2 overlap joint seam the gap R-joining such as be.

This track processing technology does not increase difficulty, and when driving wheel contact with the slit is local, avoided instantaneous vacant state, do not clash into, vibrate and noise significantly reduces the track long service life.Travel applicable to bullet train.

Claims

1, a kind of make train when walking reduce vibration prevent the bullet train track that clashes into, the perpendicular end surface that it is characterized in that I-shaped track 1 be the inclined-plane track during by fixture 2 overlap joints seam be wide R-joining.

2, a kind ofly make train when walking reduce vibration to prevent the bullet train track that clashes into, an end face that it is characterized in that I-shaped track 1 has convex rail 4, the spill rail 3 of its other end for matching with convex rail 4, track form broken line shape slit when being overlapped by fixture 2.

3, track according to claim 2 it is characterized in that the convex rail 4 of described track protrudes for the track two ends are a side, and opposite side is a spill, and overlap joint forms the broken line type slit.
