A ballast switch drive mechanism 100 according to an embodiment of the present disclosure will be described below with reference to the drawings.

Referring to FIG. 1, a turn switch drive mechanism 100 according to an embodiment of the present disclosure may include a plurality of drive units 110 that may be spaced apart along an extending direction of the ballast beam 200. Here, the extending direction of the ballast beam can be understood as the longitudinal direction of the ballast beam, for example, the front-rear direction as shown in FIG. In the description of the present disclosure, "a plurality" means two or more, for example, three, four, etc., unless otherwise stated. For example, as shown in FIG. 1, the drive unit 110 may be four.

As shown in FIGS. 2 and 3, each of the drive units 110 can include a mobile gantry 10, a stationary guide 20, and a drive unit 30. The moving gantry 10 is connected to the ballast beam 200 by the first moving pair 101 and the rotating pair 103, that is, the moving gantry 10 is connected to the ballast beam 200, and can be moved relative to the ballast beam 200 by the movement of the first moving pair 101. It is also possible to pivot relative to the ballast beam 200 by the rotation of the rotating pair 103.
