The multi-point lifting balance assembly comprises two power transmission assemblies, a lifting appliance assembly, a bridge steel box girder and a support assembly, each power transmission assembly comprises a winch, a steel wire rope, a loose pulley assembly, a luffing mechanism and a redirection pulley block, and each redirection pulley block comprises a fixed pulley block, a movable pulley block and a redirection pulley. The steel wire rope is wound around the fixed pulley block and the movable pulley block in the vertical direction, extends in the horizontal direction and is connected with the other redirection pulley block through the redirection pulley which is horizontally arranged; the lifting appliance assembly is connected to the movable pulley block and transfers the bridge steel box girder. The two power transmission assemblies, the lifting appliance assembly, the bridge steel box girder and the support assembly are matched for lifting, the fixed pulley block, the movable pulley block and the redirection pulley work cooperatively, the lifting efficiency is high, the stability is good, and the problems that materials are wasted and the construction efficiency is low are solved.

    本发明公开了一种钢梁吊装用多点起吊平衡组件,包括2个动力传递组件、吊具组件、桥梁钢箱梁、支架组件,每一动力传递组件包括卷扬机、钢丝绳、游轮组件、变幅机构、改向滑轮组,改向滑轮组包括定滑轮组、动滑轮组、改向滑轮,钢丝绳沿上下方向绕经定滑轮组、动滑轮组后,沿水平方向延伸并绕经水平设置的改向滑轮与另一改向滑轮组连接;吊具组件衔接于动滑轮组并调动桥梁钢箱梁。采用2个动力传递组件、吊具组件、桥梁钢箱梁、支架组件的配合进行吊装,定滑轮组、动滑轮组、改向滑轮协同运作,吊装效率高且稳定性好,解决了材料浪费、施工功效低下的问题。
