The invention discloses a municipal steel structure bridge lifting device and method. The municipal steel structure bridge lifting device comprises a crane, the crane is provided with a lifting arm and lifting ropes, the head of the lifting arm is provided with a plurality of threading holes with downward openings, and one lifting rope penetrates through each threading hole. In conclusion, according to the municipal steel structure bridge lifting device, the gravity center position does not need to be determined before a municipal steel structure bridge is lifted, the lifting ropes can be bound to all positions of the municipal steel structure bridge at will, then after the municipal steel structure bridge is lifted, the posture of the municipal steel structure bridge is adjusted in the air till the municipal steel structure bridge is horizontal, then the municipal steel structure bridge can be lifted, the gravity center does not need to be searched and calculated before lifting, so that a large amount of time is saved, lifting and total lifting time consumption of the municipal steel structure bridge are greatly shortened, and the method for adjusting the posture of the municipal steel structure bridge in the air is very simple, very suitable for commercial application and good in practicability.
本发明公开了一种市政钢结构桥梁起吊装置及方法,包括吊车,所述吊车具有吊臂和吊绳,所述吊臂的头部设有多个开口朝下的穿线孔,每个穿线孔贯穿一根吊绳。综上所述,本申请所述市政钢结构桥梁起吊装置在起吊市政钢结构桥梁前无需确定重心位置,吊绳可随意捆绑在市政钢结构桥梁的各处,而后在吊起市政钢结构桥梁后在空中调整市政钢结构桥梁的姿态,直至其水平,然后即可对市政钢结构桥梁进行吊装,由于起吊前不用寻找计算重心,因此节省了大量时间,大大缩短了市政钢结构桥梁起吊和吊装总耗时,而且在空中调整市政钢结构桥梁的姿态的方法也十分简单,非常适合商业化应用,实用性好。
