摘　　要：在深水大吨位沉船打捞作业工程中,300 m以深的海底环境压力让现有饱和潜水技术无法企及,复杂的海底工艺场景超出了遥控水下机器人作业范围,这限制了我国深水大吨位沉船的整体应急打捞能力。针对传统打捞方法的不足,提出了一种沉船整体抱捞方法,采用多组大型液压抱爪实现海底沉船的抱捞作业。针对我国附近水域海底沉船抱捞作业需求,设计了一组沉船打捞电液抱抓驱动系统,以深水电机驱动液压泵为动力源,由4支协同作业的液压缸实现抱抓作业,单缸最大输出力200 t。开展了液压回路设计,基于AMESim平台建立了电液回路仿真模型,分析了系统在变负载工况下工作性能,验证了设计合理性。在完成回路设计的基础上,开展了液压系统关键液压元器件选型,完成了阀控箱耐压防水适应性设计,压力补偿式泵站设计,以及系统的整体布置与安装设计工作。In the deep-water large-tonnage wreck salvage project,the existing saturation diving technology cannot reach the depth of more than 300 meters.The complex seabed is beyond the working scope of underwater robots,which limits the salvage capability of my country's deep-water large-tonnage sunken ships.In view of the deficiencies of the existing technology,this paper proposes a method for the overall holding and fishing of a sunken ship,using a deep-water motor as the power source of the hydraulic pump.The four hydraulic cylinders work together to realize the grasping operation.The hydraulic circuit design is carried out,and the rationality of the circuit is verified based on the AMESim platform.
