船载海吊关键部件设计

船载海吊是海洋工程装备的重要工具,对提高效率、安全生产有重要意义。船载海吊是通过回转动作和改变起重臂的跨度,将起重吊钩移至本方货场上方,吊起货物后移至目标船的货场上方,放下货物。与普通起重机械相比,船载海吊没有行走机构,其关键部件包括起升机构、回转机构和变幅机构,即通过起升机构提升或下降货物,通过回转机构在水平方向沿圆弧弧线运移物品,通过变幅机构改变吊臂倾角实现变幅。当然还需要考虑海上波浪运动对作业的影响,船载海吊还包括波浪补偿装置,提出了海浪补偿系统的操作流程。最后,基于AutoCAD对船载海吊进行了三维建模。

Design of key components of ship-mounted sea crane

Ship-mounted sea crane is the main tool of ocean engineering equipments to improve efficiency and safety.It lays its hook above cargo,picks up loads,rotates,and then puts down cargo on target ship through slewing and luffing movements.Compared with common crane,it hasn't travelling mechanism.So its key components include hoisting mechanism,slewing mechanism,luffing mechanism and wave compensation equipments.Hoisting mechanism loads or unloads cargo.Slewing mechanism can turn clockwise or counterclockwise ho...
