Method for installing large-tonnage component of large-span steel box arch bridge
The invention relates to a method for installing a large-tonnage component of a large-span steel box arch bridge, which is characterized in that two arch cranes are respectively arranged on two arch ribs, each arch crane is provided with a hoisting winch and a balancing winch, and the two arch cranes on the same arch rib have a certain distance and are connected through a connecting rope; a distance adjusting steel wire rope is arranged between every two arch cranes opposite to each other in the transverse bridge direction on the two arch ribs, and the two ends of the distance adjusting steel wire rope are connected with balance winches on the two arch cranes respectively; the four arch cranes are dragged by traction winches arranged at the two ends of the bridge to walk on the arch ribs in a no-load mode, the distance adjusting steel wire ropes are in a relaxed state in the walking process, the arch cranes on the two arch ribs can automatically adapt to the distance change of the two arch ribs, and when the arch cranes walk to the lifting position, the distance adjusting steel wire ropes are tightened by balance winches, and the distance is adjusted. And the hoisting winch lowers the hoisting steel wire rope hoisting component. The device is suitable for uniform-section and variable-section arch bridges, can hoist large-section and large-tonnage components, and is high in construction efficiency.
本发明涉及一种大跨度钢箱拱桥大吨位构件安装方法，在两幅拱肋分别设置两台拱上吊机，每台拱上吊机上设一台起重卷扬机和一台平衡卷扬机，同一拱肋上的两台拱上吊机有一定间距并通过连接绳连接，两拱肋上横桥向相对的每两台拱上吊机间设置调距钢丝绳，调距钢丝绳两端分别与两拱上吊机上的平衡卷扬机连接；4台拱上吊机通过设置在桥两端的牵引卷扬机牵引在拱肋上空载行走，行走过程中调距钢丝绳处于放松状态，使两拱肋上的拱上吊机可自动适应两幅拱肋的间距变化，行走到起吊位置，平衡卷扬机收紧调距钢丝绳，起重卷扬机下放起重钢丝绳吊装构件。本发明对等截面和变截面拱桥均适用，且能够起吊大节段大吨位构件，施工效率高。
