The invention provides an LNG ventilation mast frame for an LNG dual-fuel ship. The LNG ventilation mast frame comprises a mast frame structure, a mast frame structure bottom supporting column steel pipe, a middle supporting column steel pipe, a top supporting column steel pipe, a top supporting steel pipe and a lower middle supporting steel pipe. Two middle strut steel pipes are connected with the bottom strut steel pipe through base plates, and the other two middle strut steel pipes are obliquely fixed to the top end of the chimney; the bottom ends of the four top supporting column steel pipes are connected to the top ends of the four middle supporting column steel pipes in a one-to-one correspondence mode through blind plate flanges respectively. A plurality of middle lower supporting steel pipes are connected between the adjacent bottom supporting column steel pipes and between the adjacent middle supporting column steel pipes; a plurality of top supporting steel pipes are connected between the adjacent top supporting column steel pipes; the pipe diameters of the bottom strut steel pipe, the middle strut steel pipe and the top strut steel pipe are sequentially reduced. According to the LNG ventilation mast frame for the LNG dual-fuel ship, the weight of the mast frame is reduced on the basis that the original strength is guaranteed, the structural style is simplified, and an optimal arrangement scheme combined with a general drawing arrangement is provided.

    本发明提供一种用于LNG双燃料船的LNG透气桅架,包括桅架结构,桅架结构底部支柱钢管、中部支柱钢管、顶部支柱钢管、顶部支撑钢管和中下部支撑钢管;两中部支柱钢管通过垫板连接底部支柱钢管,另两中部支柱钢管倾斜地固定于烟囱的顶端;四顶部支柱钢管的底端分别通过一盲板法兰一一对应地连接于四中部支柱钢管的顶端;相邻底部支柱钢管之间和相邻中部支柱钢管之间连接有若干中下部支撑钢管;相邻顶部支柱钢管之间连接有若干顶部支撑钢管;底部支柱钢管、中部支柱钢管和顶部支柱钢管的管径依次减小。本发明的一种用于LNG双燃料船的LNG透气桅架,在保证原有强度基础上减轻桅架重量,简化结构型式,并提出结合总图布置最优的布置方案。
