Abstract
A device for the reprofiling of a rail on a railway track comprises a rigid frame (10) connected to the framing of a railroad vehicle by a lifting arrangement which permits a light running of the railroad vehicle, and at least one grinding unit (11,12). Each grinding unit (11,12) is mounted on a support (13) in such a way that it can displace itself linearly to move the grinding wheel towards and away from the surface of the rail to be grinded. The grinding wheel's axis is located in a plane perpendicular to the longitudinal axis of the rail (1,2) but does not intersect it so that the contact line of the grinding wheel with the surface of the rail (1,2) will be located in a plane perpendicular to the longitudinal axis of the rail. The support (13) is mounted to the frame (10) by cranks (16) which together with the frame and the support form a deformable parallelogram which permits the support to move itself transversally with respect to the frame (10). The support (13) comprises at least one support roller (17) and a jack (18), connecting this support (13) to the frame (10) and tending to apply this support roller against one of the sides of the rail (1,2) in close proximity to the grinding unit (11,12).
