DEVICE FOR MILL ROLLS ASSEMBLY REPLACEMENT Russian patent published in 2012 - IPC B21B31/08 

FIELD: process engineering.

SUBSTANCE: proposed device comprises moving plate and rack drive arranged between bed thrust surface and rolls assembly and rolls lifting mechanism. Rack drive rack is mounted on said plate joint with rack drive gear wheel on the mill drive side, while said rolls lifting mechanism is made up of two identical lifting support rolls fitted on eccentric shafts arranged on sides of drive and rolls assembly replacement. Working surfaces of lifting support rolls are arranged on plate bottom side while support roll is arranged above the plate on mill drive side. Clearance is created between support roll working surface and top surface of the plate in its lower position, its size being equal to rolls assembly lift magnitude. Note here that eccentric shaft of rolls lifting mechanism may be driven by worm gears fitted on one shaft.

EFFECT: ease of rolls assembly operation.
