Abstract: A turnout structure, which includes at least one turnout. The at least one turnout includes a fixed beam set. The fixed beam set includes a first side beam and a second side beam. The at least one turnout further includes a movable beam set. The movable beam set is disposed between the first side beam and the second side beam to define two switchable driving channels. A top surface of the movable beam set is configured as a first locomotion surface for locomotion wheels of a railway vehicle. The movable beam set includes a rotating beam and a moving beam. A first end of the rotating beam includes a rotating center. The rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.

Abstract: A turnout structure includes at least one turnout. The at least one turnout includes: a fixed beam set including a first side beam and a second side beam, and at least two movable beam sets disposed between the first side beam and the second side beam to define at least three switchable traveling pathways. Top surfaces of the at least two movable beam sets are configured to be a first traveling surfaces for traveling wheels of a rail vehicle to travel. Each of the at least two movable beam sets includes a rotating beam and a moving beam. A rotating center is located on a first end of the rotating beam, the rotating beam is configured to rotate around the rotating center, and the moving beam is connected to a second end of the rotating beam and configured to move along a path.
