多桅杆抬吊大型筒体的新型起重控制技术

A new lifting control technology for lifting large cylinder with multi mast

多桅杆抬吊大型筒体工艺类似于"群马拉车"的原理,普遍所用的起重设备基本为电动倒链,倒链动作分别依靠人工控制,因操作人员存在主观差异性,极易导致各吊点起升不同步、受力不均匀问题,安全隐患凸显;针对该情况,本文提出了一种新型起重控制技术。

The technology of multi mast lifting large cylinder is similar to the principle of"group horse pulling car".The commonly used lifting equipment is basically electric chain fall,and the chain fall action is controlled manually.Due to the subjective differences of operators,it is easy to lead to the problems of asynchronous lifting and uneven stress at each lifting point,and the safety risks are prominent.In view of this situation,this paper proposes a new lifting control method Manufacturing technology.
