The invention belongs to the technical field of bridge construction, in particular to a hoisting device for bridge construction. The hoisting device for bridge construction comprises a hosting frame,an electric block and a controller. The bottom end of a steel wire rope of the electric block is connected with a fixing cross beam. A hinged seat is fixedly arranged at the top end of the fixing cross beam. The upper end of the hinged seat is hinged to the bottom end of the steel wire rope through a connection block. Hydraulic cavities are symmetrically formed in the fixing cross beam. First cross beam arms are arranged in the hydraulic cavities in a sliding manner. Second cross beam arms are arranged in the first cross beam arms in a sliding manner. Third cross beam arms are arranged in thesecond cross beam arms in a sliding manner. Liquid guide hole are formed between the hydraulic cavities and the first cross beam arms and the second cross beam arms. Liquid control valves are arrangedin the liquid guide holes. The upper end of the fixing cross beam is fixedly provided with a hydraulic oil tank. The hydraulic oil tank communicates with the oil guide pipe through a hydraulic oil pump. The end of the third cross beam arm is provided with multiple hooks. The hoisting device for bridge construction can conveniently hoist objects with instable gravity center, and improves the hoisting stability and safety of the objects at the same time.

    本发明属于桥梁施工技术领域,具体的说是一种桥梁施工用吊装设备;包括吊装架、电动葫芦和控制器;电动葫芦的钢丝绳底端连接有固定横梁,固定横梁的顶端固定设置有铰接座,且铰接座的上端与钢丝绳的底端通过连接块铰接设置;固定横梁内对称开设有液压腔,且液压腔内滑动设置有第一横梁臂;第一横梁臂内滑动设置有第二横梁臂,且第二横梁臂内滑动设置有第三横梁壁;液压腔与第一横梁臂和第二横梁臂之间均开设有导液孔,且导液孔内设置有液控阀;固定横梁上端固定有液压油箱,且液压油箱通过液压油泵与导油管连通;第三横梁臂的端部设置有多个挂钩;便于对重心不稳定的吊装物体进行吊装作业,同时提高了物体在吊装时的稳定性和安全性。
