The lifting appliance comprises two lifting appliance beams and two lifting box beams, the two lifting appliance beams are arranged in parallel, and a gap is formed between the two lifting appliance beams; the two hoisting box girders are arranged on the two sides of the two lifting appliance beams and detachably connected with the two lifting appliance beams, and hoisting holes are formed in the tops of the two hoisting box girders; when the lifting appliance is used for lifting, the two lifting appliance beams can abut against the upper surface and the lower surface of the roughing mill rack, the two middle supporting seats can abut against the side face and the top face of a middle groove of the roughing mill rack, and unloading blocks or two middle supporting seats are detachably installed at the tops of the two lifting appliance beams. Therefore, the hoisting tool can fasten the roughing mill rack tightly, the roughing mill rack does not shake in the hoisting process, the heavy roughing mill rack can be hoisted conveniently, and the hoisting tool is in direct contact with the roughing mill rack, so that the requirement for the height of a travelling crane in a plant can be greatly reduced; and the hoisting operation can also be carried out in a workshop with limited space.

    本发明涉及一种用于大型粗轧机机架的吊具,包括两个吊具梁和两个吊装箱梁,两个吊具梁平行设置,中间具有间隙;两个吊装箱梁设置在两个吊具梁的两侧,与两个吊具梁可拆卸连接,两个吊装箱梁的顶部设置有吊装孔眼;两个吊具梁的顶部可拆卸安装有卸车块或者两个中间支撑座,本发明吊装吊具进行吊装时,两个吊具梁能够顶住粗轧机机架的上表面和下表面,两个中间支撑座能够顶住粗轧机机架的中间槽的侧面和顶面,从而使得吊装吊具能够紧固的扣住粗轧机机架,在吊装过程中粗轧机机架不会晃动,方便对重量重的粗轧机机架进行吊装,吊装吊具是直接与粗轧机机架接触,这样能够大大减少厂房内对行车的高度要求,在空间受限的厂房内也能进行吊装作业。
