The role of steel rails supports and guides the train wheels, provides a surface with less resistance for wheel rolling, bears the force of the train wheels and spreads them on the railway sleepers, and is used as a track circuit in the electrified railway and automatic block sections. Steel rails should have sufficient rigidity, toughness, hardness, rough top surface and other characteristics.
Railway fasteners are divided into rail joint fasteners and intermediate rail fasteners. The role of rail joint fasteners is to connect the rail and the joint between the rail. The function of the middle rail fasteners is to fasten the rails to the rail sleepers, which can be divided into wooden sleepers railway fastening system and concrete sleepers railway fastening system.
Anti-climbing equipment, due to the longitudinal force during train operation, makes steel rails even drive sleepers to move longitudinally. This phenomenon is called line crawling. If the rail seams are uneven, the sleepers will be skewed, which will cause great damage to the track and even endanger driving safety. When installing the railway anchor and the anti-climbing brace, the anti-climbing brace can use waste sleepers, and stone bars can be used instead in mountainous areas.
Railway switch, when the train is in operation, from one line to another, it is necessary to set the connection and crossing equipment of the line, that is, the railway switch. The main function of railway switch is to connect the equipment of the line that makes the rolling stock from one track to another track. There are a lot of laying on the train station, and the most used is the single turnout.
I hope that by interpreting the above information, you can not only understand the role of the components that make up the railway track, but also indirectly understand the railway track. As a professional manufacturer of railway parts, the railway parts provided by Kingrail have various types of railway equipment, reliable quality and reasonable price, which can fully meet the needs of users in various countries.
