The invention provides a large-scale hydraulic underwater grab bucket device. The large-scale hydraulic underwater grab bucket device comprises a steering system, a lifting system, a base and a hydraulic grab bucket system, wherein the steering system comprises a rotating gear; the lifting system comprises a winch, a suspension arm, a first hydraulic oil cylinder and a pulley block; the hydraulicgrab bucket system comprises a grab bucket main body and a second hydraulic oil cylinder; and the second hydraulic oil cylinder is symmetrically arranged above two half buckets of the grab bucket mainbody, so that the grab bucket main body is open and closed along with the expansion and contraction of the second hydraulic oil cylinder. The large-scale hydraulic underwater grab bucket device is simple in structure, convenient to operate, cost-saving, capable of stably and efficiently completing salvaging work of submarine articles and remarkably improving salvaging efficiency of submarine materials, particularly suitable for application and popularization in the field of devices used for salvaging ships and recovering underwater equipment, and capable of solving the problems that salvagingdevices configured by existing ships cannot meet the requirements of strength and stability and the like.
本发明提供一种大型液压水下抓斗装置,包括转向系统、升降系统、底座以及液压抓斗系统;转向系统包括旋转齿轮;升降系统包括绞车、吊臂、第一液压油缸以及滑轮组;液压抓斗系统包括抓斗主体和第二液压油缸,所述第二液压油缸分别对称设置在抓斗主体的两个半斗上方使得所述抓斗主体随着第二液压油缸的伸缩而开合。本发明所述的大型液压水下抓斗装置,结构简单,操作方便,节约成本,可以稳定高效地完成海底物品的打捞工作并显著提高海底物质打捞效率,尤其适合在船舶打捞和回收水下装备所用装置领域推广应用,解决了现有船舶配置的打捞装置不能满足强度及稳定性需求等问题。
