Apparatus for pressing movable centric rail toward wing rail

The utility model relates to an apparatus for impacting a movable centric rail toward a wing rail, wherein the movable centric rail is supported on a sliding plate (18) and may be switched between two wing rails (14, 16), and a lowering device may impact the movable centric rail on a substrate together with the wing rail at a position closed to the wing rail. At the position closed to the wing rails (14, 16), the movable centric rail (12) is impacted toward the wing rails (14, 16) by plate springs (52, 54) through a clamping force F of 50-100 Kn, when the movable centric rail is switched, the switching force is reduced by a hydraulic cylinder (62). the utility model is not only capable of switching the movable centric rail conveniently, but also capable of impacting the movable centric rail and the wing rails, so as to prevent high dynamic load in a passing region of a train and extend the service life of movable-point frogs. Operation is simple and usage is convenient.
