The first rotating rail 51 and the second rotating rail 52 are arranged in a staggered manner, so that the width dimension of the rotating frame 5 is reduced, and the width of the rack turnout of the embodiment of the invention is reduced.
In some embodiments, a first splicing surface is disposed at an end of the first short rail segment 511 close to the second long rail segment 31, a second splicing surface is disposed at an end of the second long rail segment 31 close to the first short rail segment 511, in the first position, the first splicing surface is attached to the second splicing surface, and an extending direction of the first splicing surface and the second splicing surface forms an angle with an extending direction of the second long rail segment 31 so as to abut against the first short rail segment 511 in the first position, a third splicing surface is disposed at an end of the third short rail segment 521 close to the fourth long rail segment 41, a fourth splicing surface is disposed at an end of the fourth long rail segment 41 close to the third short rail segment 521, in the second position, the third splicing surface is attached to the fourth splicing surface, and an extending direction of the third splicing surface and the fourth splicing surface forms an angle with an extending direction of the fourth long rail segment 41 so as to abut against the first short rail segment 511 in the second position.
Specifically, in the first position, the first splicing surface is attached to the second splicing surface, and an included angle is formed between the extending direction of the first splicing surface and the extending direction of the second long rail section 31, so that the first splicing surface is attached to the left rear side of the second splicing surface, and the first short rail section 511 is prevented from swinging to the right side. Therefore, on one hand, the first short rail section 511 is abutted against one end of the second long rail section 31, so that the rotating frame 5 is limited at the first position, and on the other hand, when the toothed rail train passes through the first splicing surface and the second splicing surface, the running direction of the wheel is not perpendicular to the extending direction of the first splicing surface and the second splicing surface, so that the impact of the first splicing surface and the second splicing surface on the wheels of the toothed rail train is reduced.
In the second position, the third splicing surface is attached to the fourth splicing surface, and an included angle is formed between the extending direction of the third splicing surface and the extending direction of the fourth long rail section 41, so that the third splicing surface is attached to the right rear side of the fourth splicing surface, and the third short rail section 521 is prevented from swinging to the left side. Therefore, on one hand, the third short rail section 521 abuts against one end of the fourth long rail section 41, the second side limits the rotating frame 5 at the second position, and on the other hand, when the toothed rail train passes through the third splicing surface and the fourth splicing surface, the running direction of the wheel is not perpendicular to the extending direction of the third splicing surface and the fourth splicing surface, so that the impact of the third splicing surface and the fourth splicing surface on the wheels of the toothed rail train is reduced.

The nominal radius of the first end face is the same as that of the second end face, and the first end face is in rotating assembly connection with the second end face, so that the size of a gap between the first end face and the second end face is reduced, impact of the first end face and the end face on a toothed rail train wheel is reduced, and safety of the toothed rail train is improved.
In some embodiments, the first rotating rail 51 and the second rotating rail 52 are symmetrically arranged, the rotating shaft of the rotating frame 5 is located in the extending direction of the first rail 2, and the second rail 3 and the third rail 4 are symmetrically arranged with respect to the extending direction of the first rail 2.

Thus, the extending direction of the second rail 3 and the extending direction of the third rail 4 are symmetrically arranged along the left-right direction, and the angle of the second rail 3 and the third rail 4 is maximized without increasing the width of the rack switch of the embodiment of the present invention.

In some embodiments, the track gauges of the first, second, third, first and second turning rails 2, 3, 4, 51 and 52 are the same.
