The invention provides a large roll-on-roll-off ship tail casting installation method which comprises the steps: hoisting a tail casting section AG02 insertion section to a platform trolley, and then moving the platform trolley to a folding position; erecting a head-tail target frame workbench and a theodolite fixing frame for irradiation on the tail part of the dock gate of a dock, and making reference points of head and tail bull's eyes; transversely moving the platform trolley to the tail area of the tail casting section AG02 mounting section, using a theodolite to irradiate from the stern to the bow on the basis of the made reference points of the target centers of the head and the tail, and adjusting the positions of the target centers of the auxiliary light targets to be concentric with the initial axis; transversely moving the platform trolley to a designated position and then finely adjusting up and down, and matching with technicians in a machine loading workshop for precise positioning, so that the center of a tail casting hole of the insertion section of the tail casting section AG02 coincides with the centers of the head and tail target frame workbenches; and inserting and positioning the tail casting section AG02 insertion section, and moving away the platform trolley. According to the installation method, the ship production plan implementation is ensured, and the phenomenon that the dock period is prolonged due to tail casting lag is avoided.
本发明提供了一种大型滚装船尾铸安装方法,包括将尾铸分段AG02插入段吊至平台小车上,然后将平台小车移至合拢位置;在船坞的坞门尾部上架设首尾靶架工作台和照光用经纬仪固定架,并作好首尾靶心的基准点;将平台小车横向移至尾铸分段AG02安装段的尾部区域,以做好的首尾靶心基准点为依据,用经纬仪由船尾向船首照光,调整各个辅助光靶靶心的位置,使之与初定轴线同心;将平台小车横移至指定位置后进行上下微调,配合机装车间技术人员进行精准定位,使尾铸分段AG02插入段的尾铸孔中心与首尾靶架工作台的中心重合;将尾铸分段AG02插入段进行插入定位,移走平台小车。本发明的安装方法,确保了船舶生产计划实施,没有因尾铸滞后,而造成船坞周期延长。
