At two rail junctions, the tip of two rail railheads staggers each other stretches into two into one in the railhead each other to leave the space for the expend with heat and contract with cold of rail, the train traveles on the track, and the train wheel can travel on two rail railheads at the rail junction, and the train wheel can not get into the space downwards at seam crossing.

Technical Field

The invention relates to the field of rails, in particular to connection of steel rails.

Background

The existing track technology can not realize that a track of thousands of kilometers is paved by one steel rail, a method of connecting a plurality of steel rails is generally adopted, two steel rails are arranged at the joint, two corners of the end part of one steel rail head are right angles, two corners of the end part of the other steel rail head are right angles, and gaps are reserved for thermal expansion and cold contraction of the steel rails.

Disclosure of Invention

In view of the above, the present invention provides a rail connection technology, which allows a train running on a rail to have no jolt and no vibration at the joint.

In order to achieve the effect, the invention provides a rail joint, wherein the end parts of the rail heads of the two rails are mutually staggered and extend into the rail heads of the two rails to be combined into a whole, and a gap is reserved for the expansion with heat and the contraction with cold of the rails. Therefore, the train runs on the rail, the train wheels can run on the two rail heads of the rails at the joint of the rails, the train wheels cannot enter a gap downwards at the joint, jolting and vibration are avoided, the damage to the train and the rail is reduced, and passengers on the train feel comfortable.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
