摘　　要：针对水下大型设备的重量及结构,根据试验水池和月池的尺寸,设计一种结构简单、性能可靠、成本低廉的拖曳式浮箱,作为水下大型设备机作业时的辅助起吊以及出现故障、动力突然切断等特殊情况时的应急措施。该浮箱采用全焊接结构,包括承重架、浮力外壳和起吊梁,其中承重架为框架结构,浮力外壳为钢板,起吊梁为工字梁。运用COSMOS有限元软件对浮箱和工字梁进行了强度和刚度验证,并成功地进行了水下大型设备的起吊试验,测算出该设备的水下重量。A tow- pontoon with simple structure, reliable performance and low cost has been designed to help suspend equipments and meet the urgency according to the weight and dimension of the large underwater equipments and the dimension of the experiment pool and its in -line pool. The tow -pontoon is full welded body consisting of the steel structure bearing frame and steel plate flotage crust and I - shaped suspend girder. The strength and stiffness of the pontoon and I - shaped girder was verified by COSMOS finite element software. The experiment of lifting large underwater equipment was successfully done, at the same time the weight of underwater equipment was calculated.
