The invention discloses a three-degree-of-freedom side-by-side double-segment crane structure which comprises a truss walking support, a transverse moving support, a transverse oil cylinder, a steel wire rope lifting device, a segment side-by-side lifting support and a buckle head, the bottom of the truss walking support is connected with rolling wheels, and walking on a rear matched upper support of a shield tunneling machine is achieved; the transverse moving support comprises a fixed frame and a moving frame, one end of the transverse oil cylinder is welded to the fixed frame, the other end of the transverse oil cylinder is welded to the moving frame, and the two ends of the fixed frame are welded and fixed to the truss walking support. One end of the steel wire rope lifting device is welded with the movable frame, and the other end is connected with the duct piece side-by-side lifting bracket; and the buckle head and the duct piece side-by-side lifting bracket are welded and fixed. Three-degree-of-freedom movement of the double-segment crane is achieved through the idler wheels, the transverse oil cylinders and the steel wire rope lifting structures, the function of grabbing and lifting two segments at a time is achieved by adopting the side-by-side lifting supports and connecting the two buckle head structures, and the segment transportation efficiency is improved.

    本发明公开了一种三自由度并排式双管片吊机结构,包括桁架行走支架、横向移动支架、横向油缸、钢丝绳提拉装置、管片并排提升支架和扣头,所述桁架行走支架底部连接滚轮、实现在盾构机后配套上部支架上行走;所述横向移动支架包括固定框架和移动框架,所述横向油缸一端与固定框架焊接,另一端与移动框架焊接,固定框架两端与桁架行走支架焊接固定;所述钢丝绳提拉装置一端与移动框架焊接,另一端与管片并排提升支架连接;所述扣头与管片并排提升支架焊接固定。本发明通过滚轮、横向油缸和钢丝绳提升结构实现双管片吊机的三自由度移动,采用并排提升支架,连接两个扣头结构,实现一次性抓举两个管片的功能,提高了管片运输的效率。
