The switch back process of the three-way switch structure 100 is described in detail below with reference to the examples in fig. 1-2 and 5-8:
the three switch beams 202 are respectively a first switch beam 2021, a second switch beam 2022 and a third switch beam 2023 which are separated from each other, when the switch beam assembly is controlled to rotate integrally relative to the rotating shaft 211 to the position shown in fig. 5-6, the first switch beam 11 is in butt joint with the first switch beam 2021, and the other end (the rear end shown in fig. 5-6) of the first switch beam 11 is in butt joint with the line main beam 201, so that the rail vehicle is driven in from the line main beam 201, passes through the first switch beam 11 and enters the first switch beam 2021, and the passing requirement of the rail vehicle from the line main beam 201 to the first switch beam 2021 can be met.
