Abstract
A roll stand having a roll centered on an axis and provided at one end with a journal block is provided with a roll-shifting apparatus which comprises an outer frame fixed relative to the stand at the journal block, a pair of arms extending parallel to one another and having outer ends pivoted on the outer frame at a common arm axis generally perpendicular to the roll axis and inner arms adjacent the block, and actuators engaged between the inner arm ends and the outer frame for vertically displacing the inner arm ends with pivoting of the arms about the arm axis to a position with the inner arm ends generally level with the journal block. An inner frame slides perpendicular to the arm axis on the arms and carries a grab mount pivotal about an inner axis parallel to the arm axis. A grab carried on the mount is axially couplable with the journal block. Another actuator, once again typically a heavy-duty double-acting hydraulic ram, has an inner end pivoted at the arm axis on the outer frame and an outer end pivoted on the inner frame for sliding the frame along the arms and thereby axially displacing the roll coupled to the grab.
