According to one aspect of the invention, the mounting method of the large-tonnage bridge crane in the tunnel is provided, the large-tonnage bridge frame is disassembled into two main beams, and the main beams of the large-tonnage bridge crane are respectively hoisted in place and then assembled into a whole by adopting a small-tonnage truck crane capable of entering a mounting room in the tunnel; the large-tonnage bridge crane is installed in the narrow space in the tunnel ingeniously, the hoisting efficiency is improved, and meanwhile the problem of position changing of the main trolley and the auxiliary trolley in the later period can be solved.
本发明提供了一种根据本发明的一个方面,提供了一种隧洞内大吨位桥式起重机的安装方法,将大车桥架拆解成两条主梁,采用能进入隧洞内安装间的小吨位汽车吊先将大车主梁分别吊装到位再装配成一体,然后采用在安装间穹顶和端部预埋设吊点,使用卷扬机的方式吊装两台小车,巧妙地在隧洞内这样狭小的空间中安装了大吨位桥式起重机,并提高了吊装效率,同时也可解决后期主小车与副小车换位的问题。
