Large continuous casting ladle turret slewing bearing replacing support and replacing method
The invention discloses a large continuous casting ladle turret slewing bearing replacing support and a replacing method. The large continuous casting ladle turret slewing bearing replacing support comprises a rectangular supporting frame body and a jacking mechanism. The supporting frame body comprises four bottom plates, four supporting stand columns, horizontal supports, an inclined support and a base plate. The bottom plates are arranged above a concrete foundation, the supporting stand columns are fixedly arranged above the bottom plates, the horizontal supports are transversely arranged at the upper end and the lower end between the supporting stand columns below two fork arms of a rotary arm, and the inclined support is arranged in the middle of the supporting stand columns; and steel plates with the same section size are welded to the top ends of the supporting stand columns, and the jacking mechanism and a plurality of base plates are longitudinally arranged above the steel plate and used for underlaying a slewing bearing structure. A supporting system is mainly adopted, the upper structure of the slewing bearing is jacked by a certain height in situ and then horizontally moved out of the slewing bearing, and a traveling crane is adopted for hoisting and moving, so that the traveling crane utilization rate is effectively increased. Four jacks are adopted for synchronous vertical jacking, position alignment is not needed during reinstallation and positioning, the installation difficulty is lowered, and the safety risk during structure displacement is reduced.
本发明公开了大型连铸钢包回转台回转支承更换支架及更换方法，包括矩形支撑架体和顶升机构；所述支撑架体包括四块底板、四根支撑立柱、水平支撑、斜撑和垫板；其中，底板设置在砼基础上方，底板的上方固定设置支撑立柱，在回转臂两个叉臂下方的支撑立柱之间上、下两端横向均设置水平支撑，中间设置斜撑；支撑立柱的顶端焊接同截面尺寸的钢板，钢板上方纵向设置顶升机构和若干垫板，用于垫起回转支承结构。本发明主要采用支撑体系，原地将回转支承上部结构顶升一定高度，然后水平移出回转支承，采用行车吊移，有效提高行车利用率。采用4台千斤顶同步垂直顶升，回装定位时不需要进行位置找正，降低了安装难度，减少了结构移位时的安全风险。
