Abstract

The utility model relates to a V-shaped rail joint. A V-shaped structure is adoption to replace the existing structure between two rails without changing the joint way of two existing rails. The utility model reduces the strike of train wheels to rails, lowers the noise, and enhances the service life of the rails and the locomotives.

Description

"V"-shape rail joint

The utility model relates to railway transport field, is specially adapted to the change of rail joint structure.

The rail joint that present domestic railway is laid all leaves lateral clearance, this gap has solved the rising-heat contracting-cold problem of rail well, guaranteed the traffic safety of train, but many drawbacks is also brought in this gap, the one, increased the bump of locomotive to rail, shortened the application life of train; The 2nd, when grinding joint, wheel produces the impact sound and the sense of jolting, bring annoying noise and unstable sense, particularly driving at night to passenger on the car, impact sound makes the passenger be difficult to fall asleep, and causes noise pollution also for railway resident along the line.

The purpose of this utility model is to change the structure of present rail joint, designs a kind of " V " sections rail joint, and the rigidity that neither influences rail can reduce the bump of locomotive butt joint again to greatest extent, reduces the noise and the sense of jolting that bump is produced.

The technical solution of the utility model is: go out 60 ° of " V " type grooves in that an end of a rail is cold rolling, the other end is cold rolling to go out 60 ° of " V " type tips, " V " type tip of a rail and " V " type groove of another one steel rail are coincide, but when laying a railway track, still stay the rise gap of shrinkage of heat supply, when train wheel ground two rail joint places, because what wheel touched is not lateral clearance, but gap sideling, this has just significantly reduced the bump of wheel to rail, reduce noise, improved the stability of train driving.

The utility model only need change the structure at two ends of the rail of present use, thus easily manufactured, do not change the connected mode of present two rail, convenient construction simultaneously again.

The utility model concrete structure is provided by following examples and accompanying drawing

Fig. 1 is according to the two rails connection diagram that the utility model proposes

Provide description of drawings implementation method of the present utility model below:

Rolling at rail one end has 60 ° of " V " type protuberances (3), rolling at the other end of rail has 60 ° of " V " type recessed grooves (5) that the protuberance (3) of rail (1) recessed groove (4) with rail (2) is joined, and construction just becomes the damping railway of a band " V " type joint one by one.

The utility model does not change the connected mode between the existing rail two ends, only changed the structure of joint, manufacturing process is simple, suitable to be transformed existing rail track, reduction locomotive bump, raising railway and locomotive life-span in batch, reduce noise, good economic and social benefit is arranged.

Claims

1, a kind of " V " sections rail joint is characterized in that: rolling at an end of a rail has " V " type groove (5), the other end rolls to be had " V " type protuberance (3).

2, according to a kind of " V " sections rail joint of claim 1, it is characterized in that: the angle of said " V " type is 60 °.

3, according to a kind of " V " sections rail joint of claim 1, it is characterized in that: the method for attachment between two rails is that the protuberance (3) of a rail " V " stretches into another root rail " V " type recess (4) and angle unanimity, and leaves the rising-heat contracting-cold gap.
