The swing track 1 comprises a swing track beam 11 and a swing track 12; the upper part of the swing track beam 11 is connected with the sliding part 21 of the sliding support column 2, and a transverse driving mechanism 22 is arranged between the swing track beam 11 and the sliding support column 2; the swing rail 12 is continuously provided at a lower portion of the swing rail beam 11.

The walking direction of the fixed track 3 and the walking direction of the swing track 1 form an acute angle or are positioned on the same straight line. The walking direction of the fixed track 3 and the walking direction of the swing track 1 form an acute included angle or are positioned on the same straight line, so that the switching angle between the swing track 1 and the fixed track 3 is not too large, and the swing track 1 can have enough time to be switched and butted with any fixed track 3; and when the train runs from the swing track 1 to the fixed track 3, the train does not run unstably due to the overlarge switching angle.

Referring specifically to fig. 2-4, fig. 2-4 are top views of the switch mechanism connection provided by the embodiment of fig. 1. As shown in fig. 2 to 4, when the suspension type rail vehicle passes through the turnout track from the uppermost fixed track 3 in fig. 2, the swing end surface 13 of the swing track 1 is aligned with the fixed end surface 33 of the uppermost fixed track 3.

However, in fig. 1, the traverse driving mechanism 22 is configured such that when the swing track beam 11 is driven to swing in the traverse direction, the swing track beam 11 is easily bent at a position of a cross section in the traverse direction, and if the bending angle is too large, the swing track beam 11 is easily broken, and in order to avoid this, as shown in fig. 5, the swing track beam 11 includes: a continuous length of first body 111; a plurality of sections of second bodies 112 arranged in mirror symmetry with the first body 111, wherein a preset gap 113 is left between adjacent second bodies 112 in the plurality of sections of second bodies 112; and a reinforcing body 114 having both ends connected to the upper portions of the first body 111 and the multi-stage second body 112, respectively.
