Claims

[Claims for Utility Model Registration] A roll changing device for changing the upper roll and lower roll of a roll stand, comprising an axis parallel to the upper roll provided on an upper chock externally fitted on both ends of the upper roll. A pair of rocking bodies that can swing around, an upper wheel supported by the rocking bodies, and a locking part that releasably engages with an engaging part provided on the upper chock as the roll moves in the longitudinal direction. A lifting cylinder at the tip of the rod, a pair of upper tracks for rolling the upper wheels, which project a predetermined length on the side opposite to the roll drive device of the roll stand and are installed in the width direction of the stand above the upper roll; At least a pair of wheels provided on the underside of a lower chock that is fitted onto both ends and is supported by a lower cylinder so as to be freely raised and lowered, and a pair of lower tracks for rolling the wheels installed in the width direction of the stand below the lower roll. , a removable spacer piece of a predetermined thickness that is interposed between the upper and lower chock when replacing the rolls, and a pedestal having a track having the same spacing and height as the lower track on the side where the upper track protrudes outward from the roll stand. A roll changing device comprising:
