Large-span steel-concrete composite bridge large-section steel truss girder erecting system and construction method
The invention relates to a large-span steel-concrete composite bridge large-section steel truss girder erecting system which comprises a near-tower end girder erecting system and a steel truss girderassembling system. The near-tower end beam erecting system comprises a main tower gantry, an auxiliary hole traction system, a pulley block and a temporary sling. The steel truss girder assembling system is mainly composed of a cable crane walking mechanism, an auxiliary hole traction system and a connecting panel. The main tower gantry comprises stand columns and a gantry main truss. The auxiliary hole traction system is installed on an operation platform and connects and fixes the two ends of a main cable. The cable crane walking mechanism is installed on the main cable, and the top of the cable crane walking mechanism is suspended to the gantry main truss at the top of the main tower gantry through a steel wire rope. The system has the beneficial effects that an easy-to-disassemble anti-collision frame is arranged on the outer side of the auxiliary hole traction system, the traction system can be protected against collision during operation, and the anti-collision frame is simple instructure, low in manufacturing cost and convenient to assemble and disassemble.
本发明涉及一种大跨钢‑混组合桥大节段钢桁梁架设系统，包括近塔端梁架设系统和钢桁梁拼装系统；所述近塔端梁架设系统包括主塔门架、副孔牵引系统、滑轮组和临时吊索，所述钢桁梁拼装系统主要由缆载吊机行走机构、副孔牵引系统及连接面板组成；所述的主塔门架包括立柱与门架主桁架；所述的副孔牵引系统安装于作业平台上，副孔牵引系统连接并固定主缆两端；所述的缆载吊机行走机构安装在主缆上，缆载吊机行走机构顶部通过钢丝绳与主塔门架顶部的门架主桁架悬吊。本发明的有益效果是：本发明在副孔牵引系统外侧设置易拆式防撞架，可保护牵引系统在作业时被碰撞，且防撞架结构简单、制作成本低、装拆方便。
