The invention discloses a novel large structure launching device and a reinforcing structure under a deck. The device comprise a semi-submerged ship, two groups of crane rails extending along a launching route of a large structure, and two rows of a plurality of support combinations respectively corresponding to the two groups of crane rails. The two rows of support combinations respectively support the left side and the right side of the bottom of the large structure; each supporting combination comprises a hydraulic trolley and a shelf, the shelf directly supports the bottom of the large structure, the bearing capacity of the shelf is not lower than the safe working load of the hydraulic trolley, rolling wheels of the hydraulic trolley roll on the corresponding crane rails, the hydraulic trolley is provided with a lifting oil cylinder, and the lifting oil cylinder upwards supports the shelf to support the large structure; a box beam reinforcing structural body is welded to the lower surface of the semi-submerged ship deck. The invention provides a launching mode which is safer and more reliable and can reduce the operation risk, the launching efficiency of a large structure is improved, and the operation cost of a shipyard is reduced.

    本发明公开了一种大型结构物新型下水装置及甲板下加强结构,包括半潜船,还包括两组沿大型结构物的下水路线延伸的行车轨道,以及分别对应两组行车轨道的两排若干个支撑组合,两排支撑组合分别支撑大型结构物底部左右两侧;每个支撑组合均包括液压小车,和直接支撑大型结构物底部的、其承载能力不低于液压小车安全工作负荷的搁架,液压小车的滚轮在对应的行车轨道上滚动,液压小车配置有抬升油缸,抬升油缸向上托住搁架以支撑大型结构物;半潜船甲板的下表面焊接有箱型梁加强结构体。本发明提供了一种更为安全可靠、且可降低操作风险的下水方式,提高大型结构物的下水效率,降低船厂运营成本。
