Abstract

The utility model discloses a novel rail and a track thereof; the novel rail is characterized in that the full view surface shape is a parallelogram; and two ends of the parallelogram are correspondingly equal corner B and corner C with the same angle of 30 degrees. The railway track built by the rail comprises a sleeper, rails arranged on the sleeper in the same direction, and railway tracks adjacently connected into a whole by rail connectors and fixed bolts; the rail and the track are characterized in that the full view shape of the rail which is arranged on the sleeper to constitute the core of the railway track is a parallelogram; corner A and corner D out of four corners of the two ends correspond to the inclined rail of the corner E; and the connection of 50 degrees for every two rails is the butt-joint for the inclined profile clearance. The rail and the track thereof have the advantages that the rail has no flush sunken at the joint, ensure the linear contact between the wheel and the rail and lead the train to move stably without intense vibration and noise.

Description

A kind of novel rail and track thereof

Technical field

The utility model relates to the railroad track of a kind of rail and structure thereof.

Background technology

The railroad track that is at present using and building, used rail all are the flush rails that two ends are 90 degree sections, are connected between rail and the rail, are reserved with one section gap that is rising-heat contracting-cold.Therefore, on the railroad track of laying, the joint of every adjacent two lengths of rail has just formed a flush section depression, when the train wheel that travels contacts this flush section recess, the horizontal movement track of train wheel on railway line just changes, shown in Fig. 2 B, bump and friction between wheel and rail take place, tremble consumingly and noise thereby produce, what every adjacent two lengths of rail joint recess produced trembles and noise strongly, just makes the train that travels produce the noise that clocklike trembles strongly and upset pan ore deposit, the ore deposit pan of passenger's mind.

Summary of the invention

The purpose of the present utility model is: the described problem that exists at the railroad track of present rail and structure thereof, for railway construction provides a kind of novel rail and track thereof, the railroad track that uses this rail to make up, because joint in every adjacent two lengths of rail, the flush depression that is not 90 degree sections, neither one depression points on the track, wheel is on the straight line all the time with contacting of track, make train driving steady, can not produce and tremble strongly and noise.

The purpose of the present utility model realizes by implementing following technical proposals:

A kind of novel rail is characterized in that: the face of the overlooking shape parallelogram of this rail, A angle and D angle correspondent equal in four jiaos of two termination, angle is 30 °-60 °, B angle and C angle correspondent equal, angle are 150 °-120 °, and this rail is called Oblique end rail.

A kind of railroad track, include: sleeper, be laid on the sleeper rail arranged in the same way, adjacent rail is linked into an integrated entity and each lengths of rail be fixed on the railroad track that constitutes on the sleeper by the rail bolt card by rail connector and set bolt, it is characterized in that: be laid on the rail that constitutes the railroad track core component on the sleeper, be the described face shape parallelogram of overlooking, A angle and D angle correspondent equal in four jiaos of two termination, angle are 30 °-60 °; B angle and C angle correspondent equal, angle are 150 °-120 ° Oblique end rail; The connection of per two lengths of rail all is the butt joint that leaves the gap between adjacent two lengths of rail initial and end plagiocephaly sections, does not form the flush depression of 90 degree sections in the joint.

Advantage of the present utility model is: the railroad track that uses this rail to make up, owing to be not the flush depression of 90 degree sections in the joint of every adjacent two lengths of rail, wheel does not reach recess, ensure that wheel is that straight line contacts with track all the time, make train smooth travel can not produce and tremble strongly and noise.
