CA 2504962

The invention relates to a screw device for high-adjusting and aligning rails on a track infrastructure comprising a transversal cantilever beam which clamps the rail on the underside and is fixed to a long nut which is variably high guided along a high-adjusting screw. The inventive screw device is characterised in that the transversal cantilever beam is embodied in the form of a horizontal screw plate which is pivotally arranged around a horizontal axis on the long nut and on which a truck provided with a clamp fixing device for a rail base can perpendicularly move with respect to the high-adjusting screw with the aid of a second screw device.

L'invention concerne un dispositif à vis servant à régler en hauteur et à aligner des rails sur une infrastructure de voie et comprenant une potence transversale enserrant le rail par en dessous et fixée sur un écrou long (4) guidé variable en hauteur sur une vis de réglage de hauteur (3). Le dispositif à vis selon l'invention est caractérisé en ce que la potence transversale est réalisée sous forme de plaque à vis horizontale (7), qui est logée pivotante autour d'un axe horizontal (20) sur l'écrou long (7) et sur laquelle un chariot, équipé d'un dispositif de fixation par serrage (10, 11) pour le patin du rail, peut être déplacé perpendiculairement à la vis de réglage de hauteur à l'aide d'un deuxième dispositif à vis (14, 16, 17).
