The strake temporary clamping tongue structurally comprises an L-shaped clamping tongue body, a vertical panel and a horizontal panel are arranged on the clamping tongue body, an upper reed hole and a lower reed hole which are provided with parallel openings are punched in the vertical panel, an arched reed is arranged between the reed holes, the arch of the reed faces the horizontal panel, and the horizontal panel faces the horizontal panel. A reed hole is formed in the horizontal panel, symmetrical positioning hole teeth are arranged along the parallel opening of the reed hole, an upper edge folding baffle and a lower edge folding baffle are arranged along the edge of the horizontal panel respectively, and a parallel baffle structure is formed at the joint of the baffles. By means of the installation method of the temporary clamping tongue, damage to the clamping tongue due to disassembly and assembly of invar plates on the upper portion and the lower portion of a broadside process hole can be effectively avoided, welding quality is improved, the number of leakage points of a later helium test is reduced, meanwhile, working hours and material cost consumed for repairing the leakage points are reduced, and the working period of the ending stage is shortened.
本发明一种用于LNG船液货舱舷侧工艺孔位置的列板临时卡舌,其结构包括L型的卡舌本体,卡舌本体上设有立面板和水平面板,在立面板冲压出上、下两道平行开口的簧片孔,簧片孔之间为带拱形的簧片,簧片的拱形朝向水平面板,沿簧片孔的平行开口设置有对称的定位孔齿,沿水平面板的边缘分别设置上折边挡板和下折边挡板,挡板的连接处形成平行的挡板结构,本发明还涉及一种安装方法,该方法减少了重复焊接对卡舌造成的损伤及污染,使用该临时卡舌的安装方法可以有效的避免因拆装舷侧工艺孔上下的殷瓦板对卡舌造成的损伤,提高焊接质量,减少了后期氦气试验漏点数量,同时降低了对漏点修补所消耗的工时及材料成本,缩短了收尾阶段的工作周期。
