A roll changing device is applicable to a multi-roll mill. Under a roll changing state, assembly parts of the work rolls and the bearing chocks have a lateral movement space with the internal width not less than the assembly width of the work rolls and the bearing chocks in a lateral direction of the assembly parts moving along a rolling strip in a mill house, and the movement space allows another work rolls to coexist with used work rolls in the mill house before the used work rolls are pulled out. The roll changing device is provided with at least two rows of clamping heads, one row of clamping heads corresponding to an inlet side are inlet clamping heads, another row of clamping heads close to an outlet side are outlet clamping heads, each row of clamping heads comprises a pair of upper and lower clamping heads arranged in parallel.
