The invention provides a light bridge crane for an underground coal mine, and relates to the technical field of cranes, the light bridge crane comprises two groups of moving seats and a moving trolley, the middle ends of the inner sides of the two groups of moving seats are rotatably connected with a first bridge body and a second bridge body respectively, and one side of the second bridge body is provided with a connecting bridge body; the connecting bridge body is movably inserted into the first bridge body, and first guide grooves are formed in the two end faces of the first bridge body and the two end faces of the second bridge body correspondingly. A heavy object is hoisted through the hoisting assembly connected to the lower portion of the moving trolley, when the moving trolley needs to conduct slant multi-angle hoisting, only the moving assemblies below the two moving bases need to be controlled to change the moving speed, synchronization is not needed any more, and rotating connection of the first bridge body, the second bridge body and the moving bases is matched; the first bridge body and the second bridge body can change the angle in the inclined direction, and the length is adaptively changed by matching with the movable insertion of the connecting bridge body and the first bridge body, thereby adapting to different mine environments.
本发明提供了一种煤矿井下用轻型桥式起重机,涉及起重机技术领域,包括移动座和移动车,所述移动座设有两组,且两组所述移动座内侧的中端分别转动连接有第一桥体、第二桥体,所述第二桥体的一侧设有连接桥体,且连接桥体活动插设入第一桥体的内部,所述第一桥体和第二桥体的两端面均设有第一导向槽;本发明通过移动车下连接的起重组件来起吊重物,在需要移动车进行斜向多角度吊运时,只需控制两组移动座下方的移动组件改变移动的速度,不再同步,配合第一桥体、第二桥体与移动座的转动连接,即可使得第一桥体、第二桥体斜向改变角度,配合连接桥体和第一桥体的活动插设,适应性改变长度,从而适配不同的矿井环境。
