Both the straight guide plate and the curved guide plate have two sets, which are arranged on the top plate and the running surface of the turnout beam to form a limiting and guiding engagement with the guide wheels of the bogie together with the long switch rail and the short switch rail; The drive mechanism is fixed on the top wall of the turnout beam and is connected to the swing guide mechanism and the cam swing mechanism respectively. It is used to synchronously drive the long switch rail to swing and drive the short switch rail to change direction, so that the first straight guide side, the second straight guide side and the main line guide side are adjacent to each other and the guide side is adjacent to each other and the guide side is adjacent to each other. Its characteristic is that it includes the following steps: When the main line of the commutator is open to traffic, the switch machine of the drive mechanism drives the multi-stage gear transmission group to synchronously drive the swing guide mechanism and the cam tilting mechanism to move, resulting in the following actions: The long pointed rail swings, with the front end as the fulcrum of rotation and the rear end driven by the swing guide mechanism, so that the first straight guide side smoothly connects with the main line. When the short switch rail reverses direction, under the action of the cam sway mechanism, the short switch rail can sway back and forth, up and down, and left and right with the rolling support as the movable fulcrum, so that one end of the second linear guide side smoothly connects with the first linear guide side and the other end smoothly connects with the main line of the turnout beam. One side guide wheel of the commutator engages with the web of the turnout beam and the straight guide plate in sequence, while the other side guide wheel engages with the first straight guide side and the second straight guide side in sequence. When the shunting branch line is open to traffic, the drive mechanism drives the long switch rail to swing in the opposite direction, so that the first curved guide side smoothly connects with the branch line. At the same time, the drive mechanism drives the short switch rail to reverse direction, so that one end of the second curved guide side smoothly connects with the first curved guide side, and the other end smoothly connects with the branch line of the turnout beam. The guide wheel on one side of the shunting frame successively engages with the web of the turnout beam and the curved guide plate, and the guide wheel on the other side successively engages with the first curved guide side and the second curved guide side.
