The invention provides a large-tonnage bridge crane capable of being applied to various tenses. In the tunnel construction tense, rotating shafts of fixed pulley blocks are all perpendicular to a first main beam and a second main beam; when the main lifting hook is located at the upper limit position, the movable pulley block is located between the first main beam and the second main beam, and the steel wire rope is wound from the two ends of a main winch roller to the middle to the position aligned with the edges of the two fixed pulley blocks. In a production tense state, rotating shafts of the two fixed pulley blocks are parallel to the first main beam and the second main beam; the two fixed pulley blocks are respectively provided with a side pulley as a balance wheel; the steel wire rope is wound from the two ends of the main winch roller to the middle to the position aligned with the two side pulleys. The trolley disclosed by the invention adopts an ingenious structural design, so that the positions of parts on the large-tonnage bridge crane customized for construction in the tunnel can be slightly adjusted to meet the production requirements, and the equipment is fully utilized.

    本发明提供了一种可应用于多种时态的大吨位桥式起重机,隧洞施工时态时:定滑轮组的转轴都垂直于第一主梁和第二主梁;当主吊钩位于上极限位置时,动滑轮组位于第一主梁和第二主梁之间,钢丝绳从主卷扬机滚筒的两端向中部缠绕至对齐两个定滑轮组边缘的位置;生产时态时:两个定滑轮组的转轴都平行于第一主梁和第二主梁;两个定滑轮组中各有一个边滑轮作为平衡轮;钢丝绳从主卷扬机滚筒的两端向中部缠绕至对齐两个边滑轮的位置。本发明的小车采用巧妙的结构设计,使为了隧洞内施工定制的大吨位桥式起重机上的部件位置稍加调整就可以应用于生产需要,是设备得到充分利用。
