Abstract

The present railroad is connected with one section by one section rails, and has a joint seam with 10-20 mm. When the train wheel passes through the joint seam, the train generates vibration and noise. The utility model provides a new style railroad rail joint. An acute angle is formed between the joint seam and the longitudinal axis of symmetry of rails, when the train wheel does not yet leave the end of the first rail in the joint, the train wheel has rolled on the starting end of the second rail, so as to make the rails continuous, realize smooth transition, and the train does not generate vibration and noise. The utility model is not only suitable for new manufacturing rails, but also provides most reasonable framework for rebuilding operating railroads.

Description

Railroad rail joint

Existing railway all is to be formed by connecting by sectional rail, the interface seam (being called dilatation joint) that 10～20mm must be arranged in the junction, this interface seam is perpendicular with the vertical axis of symmetry of rail, train wheel from first section rail when second section rail transient process just passed through interface, wheel is convenient to the end collision of second section rail, produce vibrations and noise, and vibrations and noise are harmful to all, these all are those skilled in the art roads in common knowledge.People have also adopted various measures to reduce vibrations and noise, as adopt long rail to reduce joint, improve the damping design etc. of railway carriage but this all can not tackle the problem at its root.

The above-mentioned situation of total sight, find that train wheel is not to move on a continuous track, but on a track that some discontinuous points are arranged, move, wheel causes through discontinuities generation kick, if can manage to overcome the influence of these discontinuous points, it is continuous that track is become, and problem just can obtain the garden and completely solve.Purpose of the present invention just is to design a kind of novel joint principle, for wheel provides a continuous track.

Solution of the present invention is that the interface of two sections rail seam is become less than 90 ° α angle to realize with vertical axis of symmetry of rail, just when wheel does not also roll across first section rail terminal, it has rolled on the top of second section rail reposefully, realize transition stably, do not produced vibrations and noise.The smaller the better certainly as for choosing of α angle, but along with the reducing cost and can improve of α angle, generally between 20 °～60 °, choose, the best is 30 °～45 °.

Be the description of the drawings below:

Fig. 1 is the vertical view of one embodiment of the present of invention.

Fig. 2,3 and Fig. 4 is respectively II-II in Fig. 1, III-III, and the cross sectional view in IV-IV cross section.

Fig. 5 is that A in Fig. 1 is to view

Fig. 6 is the vertical view of an alternative embodiment of the invention.

Fig. 1 of the present invention has provided a kind of novel rail joint, concrete structure is that the head cutter in interconnective two rails (1) and (2) becomes the wedge shape at 2 times of α angles, and the rail level that has the exterior contour in leg-of-mutton its cross section compensation block (3) identical with the exterior contour of rail and (4) to be cut into wedge shape with compensation on the top of the rail both sides of joint connecting cleats (5) and (6).Above-mentioned compensation block can be made of one with connecting cleat, also can be being soldered on the connecting cleat behind the compensation block.Above-mentioned in addition leg-of-mutton compensation block is the isosceles triangle that one or two base angle is the α angle, and its thickness is rail level thickness.So the joint of this form can be used in the track transformation that has moved,, do not need the business of railway line to stop transport as long as the rail's end portion wedging is changed the clamping plate that the system of having given has compensation block then.

Fig. 6 has represented another embodiment, and this joint form is simple, is suitable for the production of new rail, the construction of new railway.

Become an angle of slope round the interface seam that makes rail with the vertical axis of symmetry of rail in sum, this thought, those skilled in the art can adopt variety of way to realize this design.
