Rail structure capable of ascending and descending at flyover crossing of railway line

Abstract

The invention relates to a rail structure capable of ascending and descending at a flyover crossing of a railway line. The rail structure capable of ascending and descending at the flyover crossing ofthe railway line comprises a first rail line, a second rail line, a filling line and a moving mechanism. The first rail line is provided with a first notch segment, and the second rail line is provided with a second notch segment. And the moving mechanism is used for moving the filling line into the first gap segment or the second gap segment. When a train needs to pass through the first rail line, the first rail line is in a passing state, namely, the filling line is moved into the first notch segment through the moving mechanism, and therefore the train can pass through the first rail linesmoothly. And when a train needs to pass through the second rail line, the second rail line is in a passing state, the filling line is moved into the second notch segment through the moving mechanism,and the train smoothly passes through the second rail line. Therefore, the construction of bridges or culverts is reduced, the cost is saved, and the connection of upper and lower lines is realized.

Description

technical field [0001] The invention relates to the field of track technology, in particular to a liftable track structure at a three-dimensional intersection of railway lines. Background technique [0002] In recent years, with the rapid development of transportation, there are more and more railway line interchanges, such as the phenomenon of overpassing and underpassing. Traditionally, multiple railway lines at the three-dimensional intersection work independently and have track structures. The support and guidance of the lines cannot realize the connection and intercommunication between the lines. It is often necessary to build overpasses or culverts at the three-dimensional intersections of railway lines, resulting in complicated construction and huge cost. Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art and provide a rail structure that can be raised and lowered at the intersection of railway lines, which can...
