In this embodiment, the movable limiting structure is connected to the fixed portion 311.
In a specific embodiment, the fixing portion 311 includes a fixing groove 3111 formed on a surface of the fixing base 31 facing the rotating body 32; the movable limiting structure comprises an accommodating groove formed in one side of the rotating body 32 facing the fixed seat 31, a ball 322 arranged in the accommodating groove, and an elastic element 321 arranged between the bottom of the accommodating groove and the ball 322; when the rotating body 32 rotates to a fixing position 311, the balls 322 move toward the fixing position 311 (fixing groove 3111) by the thrust of the elastic member 321, and are partially received in the fixing position 311 (fixing groove 3111).
The rotating body 32 is in contact with the surface of the fixed seat 31. The accommodating groove corresponds to the fixing groove 3111, so that a cavity for accommodating the balls 322 can be formed by enclosing together. In the initial state, the elastic element 321 may be in a compressed state to support the ball 322, so that the ball 322 is located in the cavity defined by the receiving groove and the fixing groove 3111, and the limiting rotating body 32 rotates relative to the fixing base 31.

In one embodiment, the fixing groove 3111 is a spherical groove, and the depth of the fixing groove 3111 is smaller than the radius of the ball 322. This embodiment can more reliably disengage the balls 322 from the fixing grooves 3111 when the rotating body 32 moves, and improve the stability of the direction change of the rotating body 32.
In an embodiment, a dust falling hole is formed on a side of the fixing seat 31 away from the rotating body 32, and a position of the dust falling hole corresponds to a position of the fixing groove 3111 and is communicated with the fixing groove 3111.

Here, "a plurality" means two or more. In a specific example, each of the fixing positions 311 includes two fixing grooves 3111, and the two fixing grooves 3111 are symmetrically disposed with respect to a rotation center of the rotating body 32. Correspondingly, the number of the movable limiting structures is two, and the two movable limiting structures are arranged in one-to-one correspondence with the positions of the two fixing grooves 3111.
In one embodiment, there are two fixing locations 311, and two fixing locations 311 are disposed at an included angle of 90 °. I.e. the rotating body 32 will rotate 90 deg. per commutation. The track 1 reversing device is suitable for the # -shaped track 1.
Referring to fig. 1 and fig. 5, the present embodiment further provides a rail transportation system, which includes a plurality of rails 1 and a transportation vehicle 2; at least two rails 1 are crossed, an installation position is arranged between the crossed rails 1, and a rail steering device 3 is installed on the installation position; the carrier vehicle 2 comprises a vehicle body and an ejector 21 arranged in front of the vehicle body; the ejector 21 is used for rotating the rotating body 32 of the ejected track steering device 3, so that the rotating body 32 is rotated to a target fixing position, and the rotating body 32 is overlapped with the track 1 corresponding to the target fixing position.
The number of the fixing positions 311 in the track turning device 3 can be determined according to the number of the crossed tracks 1, and the included angle between the adjacent fixing positions 311 can be determined according to the included angle between the adjacent crossed tracks 1, so that the track 1 turning device is suitable for track intersections 13 in various types.
The ejector 21 may here be a push plate, which may be mounted on the head of the carriage 2. The ejector 21 is correspondingly positioned on one side of the rotary joint of the rotary body 32 and the fixed seat 31. Illustratively, for the # -shaped track 1, there are four track intersections 13, and the four track intersections 13 are each provided with a track steering device 3.
