针对狭窄厂房空间150 t钢包回转台的安装,研究设计了专用的两跨双台行车联合抬吊方案。设计和制造了双台行车联合抬吊的平衡梁吊具,并针对小曲率穿索半径,设计制造了专用的尼龙吊带进行穿索吊装。通过结合过渡支架平台的设计安装,运用两跨双台行车联合抬吊的新方案,成功实施了狭窄厂房空间150 t钢包回转台的安装,并保证了安装精度,安装过程安全可靠。
Aiming at the installation of 150 t ladle turntable in a narrow plant space, a special two-span and two-station vehicle lifting scheme was researched and designed. Designed and manufactured the balance beam spreader which is supported by a pair of trains, and designed and manufactured a special nylon sling for hoisting the slings according to the curvature radius of the small curvature. Through the design and installation of the transitional support platform, the new 150 t ladle turret with narrow workshop space has been successfully implemented with the new scheme of two-span and two-stage traveling with the lifting of the ladle, and the installation accuracy is ensured and the installation process is safe and reliable.
