The invention belongs to the technical field of metallurgical rolling mill mechanical equipment installation, and particularly relates to a turnover shaft installed on the two sides of a rolling mill housing and a matched arc supporting seat of the turnover shaft, the turnover shaft comprises a shaft body and a flange, the flange and the shaft body are of an integrated structure, the flange divides the shaft body into a matching section and a supporting section, and the matching section is matched with a turnover hole in the outer side of the rolling mill housing; the supporting section is matched with the arc face on the matched arc supporting seat, and the overturning hole is located at the upper 1/3 position of the height of the memorial archway. The rolling mill housing overturning device has the beneficial effects that when no bosses exist on the two sides of a rolling mill housing, a pair of detachable cylindrical shafts are additionally arranged on the two sides of the housing to serve as overturning fulcrums to achieve overturning of the housing; the cylindrical shaft is placed on the matched arc supporting seat, and the cylindrical shaft rotates in the arc groove of the supporting seat, so that instability in the rolling mill housing overturning process can be prevented. The memorial archway overturning device is simple in structure and convenient to install, the construction period is shortened, cost is saved, and meanwhile the memorial archway overturning process is more stable and safer.
本发明属于冶金轧机机械设备安装技术领域,尤其涉及一种安装在轧机牌坊两侧的翻转轴及其配套圆弧支撑座,翻转轴包括轴体和法兰,法兰与轴体为一体式结构,法兰将轴体分成配合段和支撑段,配合段与轧机牌坊外侧的翻转孔相匹配;所述支撑段与配套圆弧支撑座上的弧面相匹配,翻转孔位于牌坊高度的上1/3处。本发明的有益效果是:解决了轧机牌坊两侧无凸台时,通过在牌坊两侧增加一对可拆卸的圆柱轴作为翻转支点来实现牌坊的翻转;圆柱轴安放在配套的圆弧支撑座上,圆柱轴通过在支撑座的圆弧槽内旋转,可以使轧机牌坊翻转过程防止失稳。结构简单,安装方便,即节省工期,又节省费用,同时牌坊的翻转的过程中也更加稳定、安全。
