【摘要】越南老街钢厂项目施工过程中,由于工程所在地偏远,大型起重机租赁困难。大型起重机进场费用昂贵,山高路远,进场一次相当不易,精确模拟吊装、合理选择起重机在本工程施工过程中显得异常重要。为了精确模拟施工,一次吊装成功,减少不必要的成本,利用SU三维软件对筛分室内的振动筛吊装过程进行吊装模拟,并用于指导现场实际吊装。结合起重机性能表,并考虑了起重机车体高度、起重机回转中心至吊臂旋转中心之间的水平距离等因素,精确模拟了施工,合理选择了起重机,取得了良好的施工效果。

[ABSTRACT]Vietnam street steel project construction process,
due to the remote location of the project,large crane rental difficult.Large crane approach is expensive, hill tall great distance, play a quite not easy, accurate simulation of hoisting, reasonable appear during the construction process in the project is very important to choose the crane.In order to accurately simulate the construction, a hoisting success, reduce unnecessary costs, vibration using SU 3D software for screening indoor screen hoisting hoisting simulation, and used to guide the actual lifting.Combined with the performance of crane, and consider the height of the vehicle body, between the crane jib crane slewing center to the center of rotation of the horizontal distance and other factors, accurate simulation of the construction, the reasonable selection of the crane, and achieves good construction effect.

1.工程概况
越南老街钢厂烧结成品筛分室在+6.05米及+9.05米平台上布置两台振动筛,筛孔分别为10mm及5mm。单台振动筛分为下部底座装置和上部振动装置,中间通过弹簧连接,外形尺寸为9250mm*3500mm*2250mm,设备到货卸车时,采用了80吨汽车吊对振动筛进行了称重,经80吨汽车吊电子显示仪确认,振动筛下部底座重量为18吨,振动筛上部(含振动装置)21吨。为了尽量减少吊装重量,控制吊装成本并满足吊装要求,将上部振动装置上的格栅板、振动电机及下部装置中的漏斗进行了保护性拆除,后期可以采用筛分室内的10吨单梁吊安装已拆除部分。拆除后,经80吨汽车吊电子显示仪再次确认,下部底座重量为16吨,上部振动装置为16.2吨。筛分室为混凝土框架结构,吊装前,框架部分已施工完毕,顶部结构框架梁标高为 +23.5米,筛分室跨距22.5米,轴线间距5米至8米不等。……
