摘要
针对门座起重机大车需旋转90°后继续行走的工况,传统方法依靠人力转动,效率低且风险高,开发出一种电动旋转的大车行走机构,运用单个液压油缸进行顶升,减速电机配合链条传动带动大车行走机构旋转,并在实际项目中得到成功运用,提高了门座起重机的转向效率,可降低人工劳动强度和生产安全隐患。
According to the working condition that portal crane needs to rotate 90°and continue to walk,the traditional method relies on manual rotation,which is low efficiency and high risk.A travelling mechanism with electric rotation is developed,which is jacked by a single hydraulic cylinder,and driven by a reduction motor and chain drive.It is successfully used in the actual project,which improves the turning efficiency of the portal crane,reduces the labor intensity and production safety risks.
