CN2158888Y - Low-noice rail - Google Patents

Abstract

The utility model relates to a novel low noise rail, which is characterized in that the two end surfaces of rail have a longitudinal angle of 35 DEG (or 145 DEG) with the rail. The utility model has the advantages of low noise, small vibration in the process of the running of train, long service life of the rail, long mechanical life of the train, simple manufacturing process, and easy realization.

Description

Low-noice rail

The utility model relates to a kind of novel rail that is used to place an iron railway.

At present, the rail that is used to place an iron railway, be the plain edition rail of continuing to use for many years, its rail two ends section is with rail and vertically becomes vertical section, when each joint rail is coupled to each other, owing to consider the influence of rail because of changed by natural climate, can produce and expand with heat and contract with cold, for preventing the rail distortion, all leave the gap of 8～10mm in the rail connection place, because the existence in this gap has formed many " depression ", when train travels on rail on rail, when wheel passes through the rail connection place, this " depression " makes train produce huge vibration and noise, influence the passenger and reaches the healthy of resident on the way, also influences train, railway, the mechanical life of bridge.

The purpose of this utility model is exactly in order to address the above problem, and has designed a kind of novel rail.

Rail of the present utility model is characterized in that the both ends of the surface of rail all vertically become 35 ° of (or 145 °) angles with rail.

Owing to adopted technique scheme, compared with prior art, when train travelled by the connection place on rail, wheel was not to sail out of in moment to save rail, be absorbed in the gap, jump onto down joint rail in moment again, but individual process arranged during by the rail connection place at wheel, be sail out of gradually save rail in, sail down the joint rail gradually into, the influence that has been produced when having eliminated by gap, rail connection place has overcome in the prior art, the problem that the noise that railway exists is big and vibration is big.

Description of drawings

Fig. 1 is the novel rail of the low noise diagrammatic sketch of bowing,

Fig. 2 is the diagrammatic sketch of rail connection place,

Fig. 3 be the A-A of Fig. 1 to figure,

Below in conjunction with accompanying drawing the utility model is further described,

The rail that the utility model is described, the both ends of the surface that it is characterized in that rail (1) vertically become 35 ° of (or 145 °) angles with rail, 35 ° of angle ends of last joint rail dock with 145 ° of angle ends of following joint rail, 145 ° of angle ends of last joint rail connect with 35 ° of angle ends of following joint rail, and the two relative outsides of rail are parallel respectively, then two road clamping plate (2) are clipped in the outside, two rail connection places respectively, pass the hole of rail and road clamping plate respectively with fastening bolt (3), and it is fixing with nut (4), can finish the butt joint of the described rail of the utility model, its technology is simple, is easy to realize that effect is obvious, this rail promptly can be used for laying large-scale transportation railways such as train, also can be used for the laying of small-sized railways such as mine,, transform transportation environment and have great importance improving the shipping mass of railway.

Claims (1)

1, the novel rail of a kind of low noise is characterized in that the both ends of the surface of rail vertically become 35 ° or 145 ° of angles with rail.
