Abstract
The utility model relates to a U-shaped seamless steel rail, which consists of a steel rail 1, a groove, a protruding groove and a steel rail 2; the center position of the steel rail 1 is provided with a groove; the center position of the steel rail 2 is provided with a protruding groove; and the protruding groove is inlaid in the groove. The utility model has a simple structure; the steel rail is able to form the seamless connecting after heat inflation and the cold shrinking; the train will not produce noises and welter; the utility model is able to reduce the speed of the train, release the fatigue of people in the train and reduce the damage degree of the road base, the steel rail and the train.
Description
Technical field: the utility model relates to a kind of a few font gapless rail.
Background technology: at present, it is two butt joints between the rail that the rail of railway connects, and then fix with junction plate, because heat expansion, the shrinkage of rail, make rail be formed with seam and connect, this connected mode has directly caused jolting of train and noise, makes too fast that the speed of train can not carry, it is tired that people's journey on the train is felt, also increased the degree of wear of train simultaneously.At present, the way that addresses this problem is the length that prolongs rail, reduce the butt joint between two rail, but the consequence of bringing like this is laying difficulty and the maintenance cost expense that has increased railway.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of a few font gapless rail is provided, and it has solved the seam that has that the butt joint back forms between two rail and has connected.The purpose of this utility model is achieved in that a few font gapless rails are made of: rail 1, groove, tongue, rail 2.Center at rail 1 has groove, has tongue in the center of rail 2, and tongue is embedded in the groove.This product structure is simple, rail forms seamless link through making rail after expanding with heat and contract with cold, and train is pressed and can not produced noise later and jolt, and can improve the speed of train, fatigue when reducing people and riding on a train has reduced the hard grind of roadbed, rail, train simultaneously and has decreased degree.
Description of drawings:
Accompanying drawing 1 is the vertical view of a few font gapless rails of the utility model.
Accompanying drawing 2 is two vertical views that several fonts link together of a few font gapless rails of the utility model.
1-rail 1 2-groove 3-tongue 4-rail 2
The specific embodiment: describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, a few font gapless rails are made of: rail 1 (1), groove (2), tongue (3), rail 2 (4).Have groove (2) in the center of rail 1 (1), have tongue (3) in the center of rail 2 (4), tongue (3) is embedded in the groove (2), forms several fonts and connects (as shown in Figure 1).
This utility model also can be that two several fonts link together (as shown in Figure 2).
Claims (1)
1, a kind of a few font gapless rail, it is made of: rail 1 (1), groove (2), tongue (3), rail 2 (4), it is characterized in that: have groove (2) in the center of rail 1 (1), have tongue (3) in the center of rail 2 (4), tongue (3) is embedded in the groove (2).
