The invention belongs to the technical field of metallurgical rolling mill mechanical equipment installation, and particularly relates to a large rolling mill stand hoisting upright U-shaped clamp which is characterized by comprising a first U-shaped clamp body, a second U-shaped clamp body, a connecting plate and an inclined support, the first U-shaped clamp body and the second U-shaped clamp body are of the same structure and are used in pairs, openings of the two U-shaped clamp bodies are transversely inserted into a rolling mill stand respectively, and after assembly is completed, the U-shaped clamp bodies are connected with the inclined support. An inclined support is arranged at the corresponding top of the U-shaped clamp body after the U-shaped clamp body is overturned, and the inclined support is propped against a window of a rolling mill stand; the outer sides of the two U-shaped clamp bodies are respectively provided with a protruding pin shaft, and a crane hook head hangs the pin shafts through a steel wire rope, so that the rolling mill stand is overturned from a horizontal state to a vertical state around the pin shafts. The lifting device has the beneficial effects that the lifting height of the hook head in the vertical overturning process of the large-scale and ultra-large-scale rolling mill stand is reduced, and the problem that a balance beam lifting appliance cannot be arranged at the top of the rolling mill stand due to the limitations of insufficient vertical space, too low height of a crane main beam and the like of the rolling mill stand is solved.
本发明属于冶金轧机机械设备安装技术领域,尤其涉及一种大型轧机机架吊装直立U形夹具,其特征在于,包括U形夹体一、U形夹体二、连接板和斜支撑,U形夹体一和U形夹体二结构相同组对使用,两个U形夹体开口分别横插在轧机机架上,组对完成后,在U形夹体翻转后对应的顶部设置一个斜支撑,斜支撑顶着轧机机架窗口;在两个U形夹体的外侧各设置一个凸出的销轴,行车钩头通过钢丝绳吊着销轴,进而使轧机机架从水平状态绕销轴翻转至直立状态。本发明的有益效果是:降低大型、超大型轧机机架直立翻转过程的钩头起升高度,解决了轧机机架由于直立空间不足、行车主梁高度过低等限制,导致轧机机架顶部无法设置平衡梁吊具的问题。
