The invention relates to the field of metallurgical equipment, in particular to a quick roller changing method and device. The method comprises the following steps of: disassembling an upper roller: connecting and locking a shaft head clamp of a lifting appliance and a shaft head of an old upper roller, loosening a quick locking mechanism corresponding to the upper roller, and lifting out the old upper roller and a bearing seat of the old upper roller; a shaft head clamping device of the lifting appliance and a shaft head of the old lower roller are connected and locked, a quick locking mechanism corresponding to the lower roller is loosened, and the quick locking mechanism and a bearing seat of the lower roller are lifted out; the new lower roller and the bearing seat of the new lower roller are hoisted to the installation position through a hoisting device and a hoisting tool, and the bearing seat of the new lower roller is fixed through a quick locking mechanism corresponding to the lower roller; the new upper roller and the bearing seat of the new upper roller are hoisted to the installation position through the hoisting device and the hoisting tool, and the bearing seat of the new upper roller is fixed through the quick locking mechanism corresponding to the upper roller. By means of the rapid roller replacing method and device, the roller replacing efficiency can be greatly improved, and the influence of roller replacing on production line operation is relieved.

    本发明涉及冶金装备领域,尤其是一种快速换辊方法及装置。该方法包括:拆卸上辊:将吊具的轴头夹持器与旧上辊的轴头相连接并锁定,松开上辊对应的快锁机构,将旧上辊连同其轴承座吊出;拆卸下辊:将吊具的轴头夹持器与旧下辊的轴头相连接并锁定,松开下辊对应的快锁机构,将连同其轴承座吊出;安装下辊:利用起吊装置通过吊具将新下辊连同其轴承座吊装至安装位置,利用下辊对应的快锁机构将新下辊的轴承座固定;安装上辊:利用起吊装置通过吊具将新上辊连同其轴承座吊装至安装位置,利用上辊对应的快锁机构将新上辊的轴承座固定。采用本申请的快速换辊方法及装置可以大幅提高换辊效率,减轻换辊对于生产线作业的影响。
