The invention discloses a hoisting construction method for a rolling mill main motor of a six-rack cold continuous rolling unit, and belongs to the technical field of hoisting construction of six-rack cold continuous rolling units. The method mainly comprises the steps of preparing a hoisting site, manufacturing a temporary stator support and a temporary rotor support, selecting a main hoisting steel wire rope buckle, selecting a stator hoisting steel wire rope and a rotor hoisting steel wire rope, installing a rolling mill main motor bottom plate and a bearing seat, placing the stator in place to the temporary stator support, installing a rotor lengthening shaft, penetrating the rotor into the stator, and hoisting the stator and the rotor together in place. The device has the advantages that displacement of the bottom plate of the main motor in the in-place process is avoided; the damage to the rotor caused by a hoisting rope buckle or a temporary rotor support is avoided; the hoisting is more convenient and accurate; and direct collision between the stator coil and the rotor iron core in the hoisting process is prevented. The method is simple, feasible, safe, reliable, short in construction period and low in construction cost.
一种六机架冷连轧机组轧机主电机吊装施工方法,属于六机架冷连轧机组吊装施工的技术领域。主要内容包括:吊装现场准备、定子临时支座和转子临时支座制作、主吊钢丝绳扣选择、定子和转子吊装钢丝绳的选择、轧机主电机底板及轴承座安装、定子就位到定子临时支座、转子加长轴安装、转子穿入定子、定子和转子一起吊装就位。优点在于,避免了主电机就位的过程中其底板发生变位;避免了吊装绳扣或转子临时支撑对转子的伤害;使吊装更方便精准;防止在吊装过程中定子线圈和转子铁芯之间发生直接碰撞。明简单易行,安全可靠,施工工期短,施工成本低。
