Abstract

It relates to an offset gapless rail of rail joint. Both ends of a bus of rail are made up of a tenon and a bucket groove. When two buses of rail joint together, two tenons plug into two corresponding bucket grooves and are fixed by conventional butt-joint fixing means. Thus, the manufacture of the rail is simple and the butt-joint is easy. Compared with prior art, the utility model enhances the smooth radius consistency at the orbit joint points; thus it reduces the attack of the rail from carriage wheels and the noise during train running and increases stationarity. It improves the traveling environment, cuts down the abrasion, extends the service life and enhances economic benefits.

Description

Offset gapless rail

The utility model belongs to rail joint design and manufacturing technology field.

The rail of present domestic use is square butt joint, and certain gentry seam that contracts is left in the joint, when wheel rolling during to the joint, owing to the collision of wheel rim to last one steel rail produces the vibration of vehicle body and the noise of playing joint is arranged; Thereby can increase intransit tired, rest of influencing resident on the way of passenger etc. greatly; Because the existence at shrinkage joint has increased the frictional force between wheel track, has reduced the transport capacity of train, has also shortened the life-span of rail and wheel.

Though disclosed CN90217778.8 of patent announcement and CN91208997.0 have overcome above-mentioned shortcoming, but their groove all is located at the centre of rail, make its manufacturing and processing technology comparatively complicated, particularly CN91208997.0 is the two ends that the joint rail are welded on the standard rail bar, processing technology is increased, increase process time, be increased to original 2.5-3 doubly because its web of the rail is wide simultaneously, increased material like this, increased weight, strengthen freight volume and be unfavorable for construction etc., inconvenience is to some extent processed and install all to tenon or rectangle hyoplastron and tongue-and-groove or rectangular channel respectively at the two ends of a joint rail in addition.Moreover the tongue-and-groove of CN90217778.8 and the equal Extension support muscle of tenon end face, tenon and tongue-and-groove two side entities are all easily decreased ring, influence application life.

The purpose of this utility model is at overcoming above-mentioned the deficiencies in the prior art, proposing the dislocation gapless rail technical scheme that a kind of tenon and tongue-and-groove are located at the same end of rail simultaneously.

The continuity of track is strengthened in the utility model decapacitation, reduces the impact of wheel track at the rail joint place, eliminates outside vibration and the noise, also have make simple, track bond conveniently, tenon and tongue-and-groove advantage such as rapid wear ring not, thereby prolonged application life of rail.Present technique also can be transformed the rail that existing railway uses.

Below in conjunction with description of drawings embodiment of the present utility model.

The utility model tongue-and-groove 1 and tenon 2 are at the same end of rail, tongue-and-groove 1 and tenon 2 are divided equally with the center line in the cross section of rail, tongue-and-groove 1 is but by the trihedral half of rectangular channel of minute tool, the end face of tenon 2 Extension support muscle 3, tongue-and-groove 1 is concordant with the supporting rib end face, the length of tenon 2 and tongue-and-groove 1 length are isometric, and the two-end structure of a joint rail is identical.Two joints are during track bonds, and the tenon 2 of rail 4 is put into the tongue-and-groove 1 of rail 5, and the tenon 2 of same rail 5 is put into fixing after tongue-and-groove 1, the two joint track bond of rail 4, and the fixing means of rail is fixed routinely.

Claims

1, a kind of dislocation gapless rail that relates to rail joint is characterized in that the two ends of a joint rail are formed by tongue-and-groove 1 and tenon 2, and tenon 2 and tongue-and-groove 1 make tongue-and-groove 1 constitute the half of rectangular channel of three walls with the cross section centerline bisects of rail.

2, dislocation gapless rail according to claim 1 is characterized in that the flute length of tenon 2 extension elongations and tongue-and-groove 1 is isometric.
