The invention relates to a lifting device for bridge construction, and belongs to the technical field of bridge equipment. The lifting device comprises a base, wherein a fixing column and a rotating motor are mounted at the upper end of the base; a fixing plate is mounted at the upper end of the fixing column; a plurality of first pulleys are mounted on one side of the bottom of the fixing plate;a lifting rope is mounted above the first pulleys; a lifting mechanism is mounted above the lifting rope; a rotating shaft is mounted at the output end of the rotating motor; a fixing disc is mountedoutside the rotating shaft; one end of the lifting rope is connected with the fixing disc, and the other end of the lifting rope is connected with a lifting basket; and one end of the rotating shaft penetrates through the fixing column and is connected with the lifting mechanism. According to the lifting device, the lifting mechanism is arranged, the distance between a second pulley and the firstpulleys is synchronously adjusted in the process of contracting and extending the lifting rope, so that the lifting speed is adjusted, and the working efficiency is improved; and the working states ofa clutch mechanism and the lifting mechanism are controlled, so that the lifting speed is controlled according to the use condition, the selectivity is high, and the lifting device is more practicaland convenient.

    本发明涉及一种桥梁施工用提升装置,属于桥梁设备技术领域,包括底座,底座上端安装有固定柱和旋转电机,固定柱上端安装有固定板,固定板底部一侧安装有多个第一滑轮,第一滑轮上方安装有吊绳,吊绳上方安装有升降机构,旋转电机的输出端安装有转轴,转轴外部安装有固定盘,吊绳一端与固定盘相连,另一端与吊筐相连,转轴一端贯穿固定柱并与升降机构相连;本发明通过设置升降机构,在对吊绳进行收缩与伸长的过程中同步对第二滑轮与第一滑轮的距离进行调整,从而实现了对提升速度进行调节,使得工作效率提高,并且设置离合机构与升降机构的工作状态进行控制,从而根据使用情况对提升速度进行控制,可选择性强,更加实用和方便。
