On-arch hoisting system for mounting large-tonnage component of variable-cross-section steel arch bridge
The invention relates to an on-arch hoisting system for mounting a large-tonnage component of a variable-cross-section steel arch bridge. The on-arch hoisting system comprises a rail system, a crane system and a traction system, the track system comprises a plurality of track seats welded on the arch ribs, and track beams are welded on the track seats along the longitudinal direction of the arch ribs; the crane system comprises four on-arch cranes, each arch rib is provided with two on-arch cranes, each on-arch crane is provided with a hoisting winch and a balancing winch, the two on-arch cranes on the same arch rib are connected through a connecting rope, and the opposite on-arch cranes on the two arch ribs are connected through a distance adjusting steel wire rope. Two ends of the distance adjusting steel wire rope are respectively connected with the balance winches on the two arch cranes; the traction system comprises a plurality of traction winches arranged at the bridge head, and the traction winches pull the arch crane to walk on the arch rib through traction cables. The method can be suitable for arch bridges with equal variable cross sections and variable cross sections, and various types of arch ribs such as steel box arches, steel pipe arches and triangular cross section arches.
本发明涉及一种变截面钢拱桥大吨位构件安装的拱上吊装系统，包括轨道系统、吊机系统和牵引系统；所述轨道系统包括多个焊接在拱肋上的轨道座，轨道座上沿拱肋纵向焊接有轨道梁；所述吊机系统包括4台拱上吊机，每幅拱肋上设置2台，每台拱上吊机设有起重卷扬机和平衡卷扬机，同一拱肋上的两台拱上吊机间通过连接绳连接，两幅拱肋上相对的拱上吊机间通过调距钢丝绳连接，调距钢丝绳两端分别与两拱上吊机上的平衡卷扬机连接；所述牵引系统包括多台设置在桥头的牵引卷扬机，牵引卷扬机通过牵引索牵引拱上吊机在拱肋上行走。本发明能适用于等变截面和变截面拱桥，以及钢箱拱、钢管拱、三角截面拱等各种型式的拱肋。
