摘要:: 某催化装置的第一再生器,质量超过800t,吊装难度很大,经过对多种方案的分析比较,最终巧妙地以再生器旁边的楼梯间为依托,在楼梯间上竖立一个小型桅杆,实现了再生器的分段吊装。文章给出了这次吊装的关键受力部件——楼梯间的受力分析计算方法,对类似吊装工程具有实用价值。
The first regenerator of a catalytic unit was difficult to be hoisted because of its large mass over 800 t. Through comparing several hoisting scenarios, an ingenious solution was chosen, that was taking the stair frame near the generator as a support and fixing a small mast on it to carry out the generator hoisting operation with its subsections. This paper gives the analysis and calculation methods of the forces acting on the stair frame that is the key structure to this hoisting operation. This method has a practical value to similar hoisting work.
