【摘要】 500 m长钢轨吊运需要多台门吊的协同配合才能完成。为提高焊轨基地吊运长钢轨的效率,防止吊运过程中长钢轨发生扭曲变形,减轻作业人员的劳动强度,采用格雷母线通信定位技术和PLC网络通信集控系统,克服多台门吊在吊运过程中出现的不同步误差,确保长钢轨在吊运过程中精确定位、同步吊运,为焊轨基地长钢轨吊运提供了一个很好的群吊集控系统方案。更多还原

【Abstract】 Cooperation of multiple gantry cranes is a stronger requirement when hoisting a long rail of 500 m.In order to improve the efficiency of long rail hoisting at the rail-welding plant,prevent long rail from distorting in the process of hoisting and reduce the labor intensity,the communication positioning technology with gray bus and the centralized control system of PLC communication network were utilized,which can eliminate the hoisting error caused by asynchrony among the multiple cranes and can ensure the accurate positioning and synchronous hoisting of long rail.So this paper provides a good method of centralized control for long rail hoisting by multiple cranes at the rail-welding plant.更多还原
