The sleeper 3 is divided into a left sleeper section 31 supported by the left rail bearing table and a right sleeper section 32 supported by the right rail bearing table; the left sleeper section 31 and the right sleeper section 32 are provided separately, i.e. are disconnected from each other in the transverse direction.
The term "lateral" as used herein refers to a direction perpendicular to the extending direction of the rail in a horizontal plane.
The F-rail 2 is divided into a left rail supported by the left sleeper section 31 and a right rail supported by the right sleeper section 32, and the distance between the left rail and the right rail is the track gauge.
The left sleeper section 31 has at least two transversely distributed fixed mounting positions relative to the left rail support table and the right sleeper section 32 relative to the right rail support table, i.e. the two sleeper sections can each change their relative position in the transverse direction relative to the respective rail support table.
For example, rail beam embedments 12, which may be bolts or other vertically extending connectors, may be provided on top of both the left and right rail blocks; correspondingly, kidney-shaped adjusting holes 33 are arranged at corresponding positions of the bottoms of the left sleeper section 31 and the right sleeper section 32, the kidney-shaped adjusting holes 33 extend transversely, the track beam embedded part 12 can penetrate into the kidney-shaped adjusting holes 33, and the left sleeper section 31 and the right sleeper section 32 are fixedly connected with the left rail bearing platform and the right rail bearing platform respectively through the cooperation of the kidney-shaped adjusting holes 33 and the kidney-shaped adjusting holes (assisted by other necessary parts such as nuts).
Of course, a specific mounting manner, for example, a plurality of round holes extending transversely to the kidney-shaped adjustment holes 33, may also be changed, and these specific arrangements may each achieve at least two fixed mounting positions of the left sleeper section 31, the right sleeper section 32 with respect to the respective rail support stand. However, it is obvious that the waist-shaped adjusting hole 33 can be arranged in a plurality of fixed installation positions by a simple structure, each fixed installation position can be continuously adjusted, and the operation process is simple and convenient.
The rail panel device of the magnetic suspension train provided by the invention divides the sleeper into the two sections of the left sleeper section 31 and the right sleeper section 32 which can freely move in the transverse direction of the line, and the two sleeper sections are respectively and fixedly connected with the left rail and the right rail, so that the distance between the left rail and the right rail can be adjusted by adjusting the fixed installation positions of the two sleeper sections, the left rail bearing table and the right rail bearing table according to the requirement, and the device can be suitable for magnetic suspension traffic systems with different gauges.
