Railroad frog for switch points and crossings
摘要:
The rigid frog for switch points and crossings with two wing rails (1, 2) and a frog point (3, 6, 4, 5) arranged therebetween, which forms with the wing rails switch openings (11) that run at an acute angle relative to each other, is characterized in that the frog point and the wing rails are elastically joined by anchor clamps on each foot side to ribbed plates (247-253). The previous unit of a rigid frog with wing rails and HB bolted point is thus resolved to individual rails. The individual rails each have their own intrinsic elasticity so that the frog behaves like a normal rail in the track in terms of oscillation and damping behavior. The previously used filling plates are no longer required. Beneath the rails are plates with which a height adjustment, especially of the wing rails (1, 2), can be effected, so that wear of the traversed surface of the wing rails can be compensated for in terms of height by changing the thickness of the spacers. The spacers (42, 43) can be elastic. Transverse to the longitudinal axis of the rails, the rail parts are secured essentially without play by ribs (39, 39a, 39b, 40, 41). In order to rule out longitudinal shifting of the point relative to the two wing rails, a correspondingly designed rail anchor is arranged in the region of the wing rail ends (FIG. 1).
