The invention provides a hoisting tool for a rolling mill housing without lifting lugs. The hoisting tool for the rolling mill housing without the lifting lugs comprises a hoisting frame for locking and fixing the upper portion of the rolling mill housing. The hoisting frame is connected with a lifting lug plate. The hoisting frame comprises an upper hoisting beam, a lower hoisting beam, a left clamping arm and a right clamping arm. One or more of hinge pins at two ends of the lower hoisting beam are convenient-to-disassemble type hinge pins. An ear plate arching upwards is arranged in the middle of the upper hoisting beam. The upper hoisting beam and the lifting lug plate are connected through a big hinge pin. The invention further provides an application method for the rolling mill housing without the lifting lugs. The application method comprises the steps that when the hoisting frame is assembled, hinge pin C for connecting the lower hoisting beam and the right clamping arm is notinstalled temporarily, and the hoisting frame is kept as an open type inlet; a crown block is adopted, the hoisting tool is moved to the upper portion of the rolling mill housing, hinge pin C is installed, and the lower hoisting beam is locked; after the housing is hoisted in position and fixed, a chain block is installed on the position of hinge pin D; the lower hoisting beam is lifted and hoisted by utilizing the chain block; and after hinge pin C is disassembled, a bottom transverse beam is put down slowly through the chain block, and disassembling of the hoisting tool is completed. According to the hoisting tool for the rolling mill housing without the lifting lugs, the operation is safe and reliable, the construction speed is high, and the construction cost is lowered.

    本发明提供一种无吊耳轧机牌坊的吊装工具,包括用于锁固轧机牌坊的上部的吊装框架,吊装框架与吊耳板相连,所述吊装框架包括上吊梁、下吊梁、左夹臂和右夹臂;下吊梁两端的销轴至少一个为便拆型销轴;上吊梁中部设有向上拱起的耳板,上吊梁与吊耳板通过大销轴相连,还提供了上述无吊耳轧机牌坊的吊装工具的使用方法:组装吊装框时用于连接下吊梁与右夹臂的销轴C暂不安装,保持吊装框为开放式入口;采用天车将本工具移动到轧机牌坊上部,安装销轴C,锁合下吊梁;牌坊吊装就位并且固定后,在销轴D处安装倒链,利用倒链提吊下吊梁,拆除销轴C后,通过倒链将底部横梁缓缓放下,完成吊具的拆卸。本发明操作安全可靠,施工速度快,节约施工成本。
