绑扎桥和克令吊筒体整合式结构设计

Intergrated Structure Design of Lashing Bridge and Deck Crane

针对配置克令吊和绑扎桥的支线集装箱船,将绑扎桥和克令吊筒体结构整合设计成一体,缩减中间甲板宽度,克令吊筒体兼做绑扎桥中间位置的剪力板,在克令吊筒体围壁上开设通道,方便克令吊筒体前后堆箱通过内绑的形式连接克令吊柱体。采用有限元法计算分析绑扎工况和克令吊作业工况下结构强度和刚度,优化中间甲板和绑扎桥设计,验证结构设计的合理性。该整合式结构设计方案,既减小货舱长度,又能提高集装箱绑扎操作的便利性。

For feeder container ships equipped with crane and lashing bridge,the lashing bridge and deck crane are integrated,reducing the width of cross decks.The crane pedestal is also used as the middle shear plate of lashing bridge.In order to achieve internal lashing for the container stack in the way of front and back of crane pedestal,the access openings are set on the wall of crane pedestal.The structural strength and stiffness are analysed through the FEM method both in lashing condition and crane operating condition,which optimizes the design of lashing bridge and cross deck,and verifies the rationality of the integrated structural design.This integrated structural design scheme reduces the length of cargo hold and improves container lashing operation.
