Abstract

The present invention provides three types of sectional gapless railroad rails. The use of the invented gapless rail can make entire railroad rail be on continuously-acting plane so as to can remove the noise resulted from running train and can raise running stability and running speed of train.

Description

Sectional seamless railway track

The present invention relates to a kind of novel railway track.

Now the conventional railway track of laying be segmented the seam rail arranged.Each rail joint place all leaves the expand with heat and contract with cold space, interval of effect of certain elimination.Therefore, when train wheel rolled across this space, train body then can be sent the rhythmical vibration sound and form the driving noise, and therefore had influence on the raising of the train roadability and the driving speed of a motor vehicle.

The present invention is intended to propose a kind of space, interval that promptly keeps the rail joint place, can eliminate the sectional seamless railway track of train driving noise again.

The objective of the invention is to reach as follows: the gap joint of conventional railway track is made into plane cut sth. askew type or concave-convex type or bore sharp type, after being connected to each other, two sections rails promptly keep (3) gap of expanding with heat and contract with cold, the rail that can make it play movement place again because of the complementary flat shape of railway track joint forms the continuous uninterrupted rail level, thereby forms the sectional seamless rail with the identical result of use of the seamless rail of continous way.

With reference to the accompanying drawings the present invention is done detailed description below:

Fig. 1 is the seamless railway track joint planform of the shape of cutting sth. askew of the present invention figure.

Fig. 2 is the seamless railway track joint planform of concave-convex of the present invention figure.

Fig. 3 is the seamless railway track joint planform of sharp cone distal of the present invention figure.

With reference to accompanying drawing, article two, cut sth. askew shape railway track joint (Fig. 1) to and together, leave at interval that space (Fig. 1 (4)) back clamps rail face (Fig. 1 (1)) and fixes it by fastening bolt with two steel clamping plate (Fig. 1 (2)), make the continuous rail of the complementary formation of the railway track joint cross sectional shape plane after the connection.(Fig. 1 (4)) are the gap of expanding with heat and contract with cold at railway track joint place.Fig. 2 is the seamless rail form of concave-convex, and other structures are all with the shape of cutting sth. askew (Fig. 1) structure.Fig. 3 is the seamless rail form of sharp cone distal, and its design feature is except the railway track joint cross section is sharp cone distal planar complementary seam, and other are all with the shape of cutting sth. askew (Fig. 1) structure and concave-convex (Fig. 2) structure.

The present invention need not big improvement on the rail manufacturing process, the not end shape that only needs to change the common railway rail gets final product.The present invention is reasonable in design, and is simple in structure, and good practical effect can reach the result of use of continous way gapless rail, real rail type for railway interests's update.

Claims

1, a kind of seamless railway track, the joint that is characterized as two sections rails of the present invention is the complementary type section structure (Fig. 1) of cutting sth. askew, and is clamped and fixed by fastening sieve bolt (Fig. 1 (3)) by two steel clamping plate (Fig. 1 (2)) two sides.

2, by the seamless railway track of claim 1 regulation, the joint that it is characterized by two sections rails is a concavo-convex complementary type section structure (Fig. 2).

3, by the seamless railway track of claim 1,2 regulations, the joint that it is characterized by two sections rails is a pointed cone complementary type section structure (Fig. 3).
