The invention relates to the field of ship and ocean engineering construction, in particular to a self-closed cabin seawater door grating device and a mounting method. The grid device comprises a grid seat, a grid and a fastener, and the grid is fixed on the grid seat through the fastener; the fastener comprises hexagon nuts, hexagon head bolts with penetrating holes and shaft bolts, and the side faces of the two hexagon nuts are provided with penetrating holes. The shaft bolt is located at the lower middle ends of the grille base and the grille and laterally penetrates through the grille base and the grille, and the two ends of the shaft bolt are fixed to the side face of the grille base through the two hexagon nuts with the penetrating holes. The hexagonal head bolts are symmetrically arranged at the top end and the two sides of the grille at the upper end of the shaft bolt so as to fix the grille base and the grille. And a balancing weight is mounted in the middle of the grating on the lower side of the shaft bolt. Stainless steel wires are used for connecting the hexagon nuts with the side faces perforated and the hexagon head bolts with the perforated holes in series so as to increase the interlocking function of the fastener, the falling risk is effectively reduced, it is ensured that the grille is safely used, and later maintenance is easier and more convenient.
本发明涉及船舶及海洋工程建造领域,尤其涉及一种自闭式机舱海水门格栅装置及安装方法。所述格栅装置包括格栅座、格栅及紧固件,所述格栅通过紧固件固定在格栅座上;所述紧固件包括六角螺母、穿孔的六角头螺栓、轴螺栓,其中两个六角螺母侧面设置穿孔;轴螺栓位于格栅座与格栅的中下端,其侧向穿过格栅座与格栅,两个端头通过穿孔的两个六角螺母固定在格栅座的侧面;所述六角头螺栓分别对称设置在轴螺栓上端的格栅顶端与两侧以固定格栅座和格栅;所述轴螺栓下侧的格栅上居中安装配重块。利用不锈钢丝把侧面穿孔的六角螺母与各穿孔的六角头螺栓进行串联以增加紧固件的互锁功能,有效减少脱落风险,确保格栅安全使用,后期维护更简单方便。
