Extra-Long and Extra-Ordinary Flexibility Attachment Device Design of Tower Crane

以柔性附着塔式起重机超长距离附着单边悬挑钢结构设计为目标,利用有限元、MATLAB和钢结构理论相结合,提出柔性附着超长超常规钢结构附墙设计方法。对TC6513-6F型塔式起重机的单边悬挑结构超长附墙杆支撑装置进行设计计算,推导得到柔性附着附墙杆内力关于起重臂旋转角度函数关系,运用MATLAB可视化方法求得附墙杆最大内力,并在ANSYS中对所设计悬挑装置整体进行静力学分析计算,得到:该设计满足工程要求。在此基础上提出适合现场使用的超长钢结构附墙装置设计方法及加工制造工艺。现场应用结果表明:超长钢结构附墙装置不仅安全可靠,而且现场安装、调整、拆卸方便。

Taking extra-long and extra-ordinary flexibility unilateral cantilever steel structure attachment device design of tower crane as a goal,puts forward a method of extra-long and extra-ordinary flexibility attachment device design of tower crane,based on finite element analysis,MATLAB and steel structure theory.According to the design calculation for extralong and extra-ordinary flexibility unilateral cantilever steel structure attachment device of TC6513-6F tower crane,the functional relation of the flexibility attachment device＇s internal force with the boom＇s rotation angle is deduced.The attachment device＇s maximum internal force is obtained with the MATLAB visualization method,the static calcalation of the whole attachment device is analyzed by ANSYS at the same time,and its design totally meets the engineering requirements.Based on that,it puts out the design methods and processing manufacturing process of extra-long attachment device,which is appropriate to the engineering fleld.The application results show that：extra-long attachment device is not only safe and reliable,but also very convenient to install,adjust and remove.
