Movable track structure at railway plane intersection

Abstract

The invention relates to a movable rail structure at a railway plane intersection. The rail structure comprises a rail main structure, a rail auxiliary structure and a guide rail assembly. A notch segment is arranged at the position, intersecting with a road, of the track main structure, and the track auxiliary structure is matched with the notch segment and correspondingly arranged in the notch segment. The guide rail assembly extends from the road surface under the notch segment to the peripheral road surface area of the road. The rail auxiliary structure is movably arranged on the guide rail assembly and can move to the notch segment or the peripheral road surface area along the guide rail assembly. When a vehicle on the road needs to pass through the plane intersection, the road is ina passing state, and the plane intersection cannot pass through, so that the vehicle can smoothly pass through the notch segment and cannot roll the rail structure at the plane intersection, the railstructure can be protected from being rolled by the vehicle, and the vehicle on the road can pass through safely; safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a movable track structure at a level crossing of a railway. Background technique [0002] In recent years, with the rapid growth of the demand for railway transportation, in order to reduce the land occupation, there are more and more plane intersections between railways and roads. Along with the increase of transportation demand, the motor vehicles at the level crossing (hereinafter referred to as level crossing) crossing the railway and the road gradually increase, making the level crossing a weak link and a dangerous section in the railway transportation. Generally, the access control methods at level crossings include manned or unguarded ones with flashing signal lights, and manual or automatic control of fence machines or retractable gates. Traffic control at level crossings can realize the safe staggering of railway operations and road operations. However, none of the...

AI Technical Summary

Problems solved by technology

Traffic control at level crossings can realize the safe staggering of railway operations and road operations. However, none of the above control methods can protect the track structure from the impact of road vehicles. When road vehicles cross the level crossing, the track structure will not be able to Avoid rolling and rolling, and this rolling action perpendicular to the line direction is not within the load range considered in the design of the track structure. Under long-term action, the steel rail may be deformed, the lower track structure may be damaged, and the smoothness of the railway track may be affected.
