ABSTRACT

Hoisting collision, difficult lifting operation, high risk for lifting operators, difficulty in optimization of process path are all problems of large equipment hoisting. By using 3D solid model, inventing real lifting environment, and introducing the ergonomics, we analyzed and simulated the hoisting process. Through optimizations of main and auxiliary cranes’ position, equipment’s placement, hoisting process, staffing, and personnel operation, we clearly reproduced the simulation process of lifting. In a relatively short period of time, we completed a one-time lifting, reduced the risk of lifting operation, realized the efficient, safe and rational operation, and finally saved the lifting cost.

1. 引言

 目前在吊装分析模拟领域，存在软件种类繁杂且功能单一、兼容性差、重复建模的问题。

 解决外形不规则和结构复杂设备的重心惯性矩、强度稳定性和局部应力等手工计算精度差、效率低的难题。

 解决吊装真实过程中干涉情况无法预判的难题。

 提前发现和解决吊装过程中偏心引起的设备旋转以及翻转作业引起的冲击载荷，避免吊装中碰撞和吊车折臂等事故发生。

 解决因履带吊车接地比压估算不准引起的吊装场地加固不足的难题，避免吊车倾覆事故发生。

CO2吸收塔自重为222 t，内径为Φ3000 mm，高度为359,300 mm，壁厚66 mm + 3 mm。梯子平台自重为12 t，工艺管线自重为6 t。吊装时吸收塔总重为240 t。吸收塔距离周围构筑物最近为5 m，场区构筑物多，四周有地上管廊，吊装作业环境复杂。通过人机工程模拟，吸收塔吊装一次完成，实现了精确、高效、安全、合理的吊装，节约了吊装成本。
