The invention relates to a hoisting method for a large rolling mill stand. The hoisting method comprises the following steps: 1) arranging a ground horizontal sliding device and a hydraulic lifting sliding device; (2) the transmission side rack is hoisted to a ground horizontal sliding device, a hoisting clamp is installed, and a gravity center hoisting tool is adjusted; (3) mainly hoisting by a hydraulic lifting and sliding device, and hoisting a transmission side rack to a position above the mounting position and rotating the transmission side rack to a vertical state by matching a workshop crane with tail slipping; (4) installation of a transmission side rack is completed; (5) the operation side rack is installed on a rolling mill base in the same mode as the step (2) to the step (4); and (6) installing a rolling mill beam. The device is suitable for the working condition that a workshop crane cannot meet the requirements for the hoisting capacity and the hoisting height, and horizontal transportation and vertical hoisting in-position of the rolling mill stand are achieved in the mode of ground horizontal sliding, aerial sliding after vertical lifting and aerial overturning.

    本发明涉及一种大型轧机机架吊装方法,包括:1)设置地面水平滑移装置及液压提升滑移装置;2)将传动侧机架吊至地面水平滑移装置上,安装吊装夹具及调整重心吊具;3)以液压提升滑移装置起吊为主、车间行车配合溜尾,将传动侧机架吊装至安装位的上方并将其转动至竖直状态;4)完成传动侧机架的安装;5)按照与步骤2)~步骤4)相同的方式将操作侧机架安装到轧机底座上;6)安装轧机横梁。本发明适用于车间行车无法满足吊装能力和吊装高度要求的工况条件,采用“地面水平滑移+竖直提升后空中滑移+空中翻转”的方式,实现轧机机架的水平运输和垂直吊装就位。
