''Seamless'' design for rail interface

Abstract

The invention relates to an inversed T-shaped tenon-and-mortise structure which is prefabricated according to standards and arranged on a rail joint. The inversed T-shaped tenon-and-mortise structures are mutually inserted and combined when being laid, and close occlusion and connection in vertical direction and horizontal direction of two sections of rail are realized on the premise of reserving hot swelling and cold shrinking axially; divisional relative displacement is performed on surface gaps of the rail; in the aspect of the whole structure in the horizontal direction, existence of absolute gaps is eliminated; a vertical groove and a horizontal groove are cut on intermediate positions on both ends of the rail joint waiting for laying; a prefabricated bloom is arranged between the grooves; an axial hot swelling and cold shrinking space is reserved; occlusion and connection of the two sections of rail in the vertical direction and the horizontal direction are performed through the built-in prefabricated bloom, and the surface gaps of the two sections of rail are partially filled, thereby 'seamless' connection is realized. The invention has the advantages of non generation of loud noise and large vibration and no waste of huge energy when trains are running, great reduction of probability of occurrence of derail accidents of the trains due to deviation on the rail joint, and realization of same efficiencies with an imaginable seamless rail.

Description

1. Technical field [0001] The "seamless" design of the rail interface of the present invention belongs to the field of railway construction in the transportation manufacturing industry. It is of epoch-making significance to reduce the noise, energy consumption and vibration of railway trains caused by the rail interface, as well as the damage to the integrity of the train and the health of passengers. 2. Background technology [0002] At present, in the field of domestic and international rail manufacturing and laying, due to the large temperature difference in the environment of the rails (the temperature difference between winter and summer can reach 60 degrees), the super-long rails cannot release the stress caused by thermal expansion and contraction, which may easily cause rail deformation. It poses a great hidden danger to the safety of trains, and the manufacturing and laying of ultra-long rails is difficult, costly, and difficult to realize. Therefore, the rails are ...

AI Technical Summary

Problems solved by technology

The bang bang bang and strong vibration caused huge noise damage and vibration damage to passengers; the strong vibration also caused great damage to the structure of the train; and the collision between its front and the raised part of the rail, will also consume a lot of energy

Second, even if the potential difference generated at the rail interface is not large, its gap will cause corresponding noise and vibration
