The invention relates to the technical field of ships, in particular to a method for lifting a ship building by using a floating dock. Comprising the following steps that S1, a bracket is welded to the top of a dock wall of the floating dock; s2, docking the refitted ship; s3, adjusting ballast water of the floating dock; s4, connecting cross beams are installed on the front and rear peripheral walls close to the upper building layer, the connecting cross beams and the bracket are welded and fixed, connecting longitudinal beams are installed on the left and right peripheral walls close to the upper building layer, and the connecting longitudinal beams and the connecting cross beams are welded and fixed; s5, a plurality of supporting toggle plates are welded; s6, cutting and separating an upper building layer; s7, the refitted ship is undocked; s8, heightening the upper part of the refitted ship; s9, the refitted ship floats into the floating dock again; s10, adjusting ballast water of the floating dock; and S11, the heightening section and an upper building layer folding seam are attached, assembled and welded. Compared with the prior art, the buoyancy of the floating dock is utilized, the separated upper building layer is lifted without a crane for hoisting, and the degree of dependence on large hoisting equipment such as a floating crane and a gantry crane is low.
本发明涉及船舶技术领域,具体地说是一种利用浮船坞进行船舶上建升高的方法。包括如下步骤:S1,将托架焊接于浮船坞的坞墙顶部;S2,改装船入坞;S3,调节浮船坞的压载水;S4,在靠近上建层的前后外围壁安装连接横梁,连接横梁与托架焊接固定,在靠近上建层的左右外围壁安装连接纵梁,连接纵梁与连接横梁焊接固定;S5,焊接若干块支撑肘板;S6,切割分离上建层;S7,改装船出坞;S8,改装船上部加高;S9,改装船再次飘浮进入浮船坞;S10,调节浮船坞压载水;S11,加高段和上建层合拢缝贴合,装配焊接。同现有技术相比,利用浮船坞自身浮力进行,分离后的上层建筑层抬高不需要吊车进行吊装,对大型吊装设备如浮吊,龙门吊依赖程度低。
