a front main track beam; and
a rear switching track beam,
wherein, the rear switching track beam comprises a central fixed track beam and a middle movable track beam; wherein,
the front main track beam is configured to switch between a straight track and a bend track by bending, the central fixed track beam is a fixed track beam, and the middle movable track beam is configured to move parallelly between the straight track and the bend track;
if the maglev train passes through the switch along the bend track, the front main track beam bends to the bend track, and the middle movable track beam parallelly moves to the bend track;
if the maglev train passes through the switch along the straight track, the front main track beam needs to be returned to the straight track, and the middle movable track beam parallelly moves to the straight track,
wherein, the middle movable track beam is a U-shaped track beam.
