“长鹰8”重型铲斗挖泥船的设计

Design of Heavy Backhoe Dredger"Chang Ying 8"

“长鹰8”采用钢桩定位,配备2套动臂、斗杆和3种斗型,可以适应不同挖深、不同土质的疏浚需求,尤其胜任坚硬土质、砾石、鹅卵石和破碎的块状礁石、岩石等底质的挖掘作业,是我国完全自主设计、建造的最大铲斗挖泥船。文章对“长鹰8”的主要特征、主尺度、总布置、动力配置、定位系统及设计中的主要考虑进行了介绍,该设计可为此类船舶的设计提供参考。

"Chang Ying 8"is positioned by heavy spuds for stability in working conditions.it equipped with 2sets of booms,dippers and 3 types of dippers,It can adapt to the dredging requirements of different digging depths and different soil qualities,especially competent for the excavation of hard soil,gravel,cobblestone and broken block reef,rock and other substrates."Chang Ying 8"is the largest backhoe dredger independently designed and constructed in China at present time.The main characteristics,main scale,general layout,power configuration,positioning system and the main considerations in the design of"Chang Ying 8"are introduced,which provides reference for the design of large backhoe dredger.
