Description

Technical Field

[0001] The utility model relates to the technical field of transportation, and more particularly to a spliced ​​track for transportation. Background Art

[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. Rail transit has the characteristics of large passenger transport capacity and high driving speed, and has become one of the important ways to solve the growing passenger transportation volume in large cities. During the operation of the train, the friction between the wheel and the rail causes the rails to vibrate violently, and the connectors at the rail joints are easily damaged by long-term collisions.

[0003] In existing technology, tracks are made of welded steel rails. This type of track has advantages such as a strong structure and smooth transmission. However, this type of track also has some disadvantages. For example, steel rail welding requires a lot of manpower and material resources, and the construction time is long. During the operation of the train, the wheel-rail friction causes the track to vibrate violently and generate loud noise, affecting nearby buildings. The track connectors are easily damaged by violent vibration and long-term collisions. The welded steel rails are difficult to disassemble and replace, and the maintenance cost is high.
