MHC150移动式多用途港口起重机电气设计

Electrical design of MHC150 mobile multi-purpose port crane

为实现港口码头移动式多功能起重机的技术应用和发展,文中叙述了MHC150移动式港口起重机的主体机构、工作原理、供电电源选型、主机构变频驱动系统选型、PLC通讯系统、抓斗/吊钩/吊具作业模式的电气控制系统、液压系统与电气通讯接口等的设计。该起重机实现了抓斗、吊钩、吊具集装箱的多种组合装卸功能,在起重机投资、适应性、维修费用和附属设施等方面比中小型岸边集装箱起重机和门座起重机具有更好的经济性和应用市场前景,可作为其替代产品。

To drive the technology application and development of the mobile multi-purpose crane in the port terminal,the design of the main mechanism,working principle,power supply selection,frequency conversion drive system selection of the main mechanism,PLC communication system,electric control system of grab/hook/spreader operation mode,hydraulic system and electric communication interface is introduced.Port crane has a variety of combined loading and unloading functions of grab,hook and spreader containers.Compared with small and medium-sized quayside container cranes and portal cranes,it has better economy and market prospects in terms of investment,adaptability,maintenance costs and ancillary facilities,and can be used as a substitute product.
