Steel box girder hoisting system
The invention provides a steel box girder hoisting system which comprises a newly-built bridge site area, a midspan transportation area, a floating crane operation area provided with a floating crane ship and a transport ship, a plurality of pier columns and a bridge site temporary support are arranged in a newly-built bridge site, an adjusting sliding groove is formed in the top of the bridge site temporary support, and a girder body fine adjustment device is arranged in the adjusting sliding groove in a sliding mode. The beam body fine adjustment device comprises a base arranged in the adjusting sliding groove in a sliding mode, a beam supporting frame arranged on the top face of the base in a sliding mode, and a driving mechanism driving the beam supporting frame to slide on the base in a reciprocating mode, wherein the moving direction of the beam supporting frame is perpendicular to the sliding direction of the base. The top face of the beam supporting frame is provided with a boundary beam cushion block used for supporting a steel box beam segment. According to the steel box girder hoisting system, the steel box girder segment is divided into a plurality of girder bodies for hoisting, and the girder body fine adjustment device capable of adjusting the positions of the girder bodies is arranged on the top surface of the construction tabletop, so that the steel box girder hoisting system can be used for hoisting construction by using a small-tonnage floating crane ship.
本发明提供了一种钢箱梁吊装系统，包括新建桥位区、中跨运输区、设置有浮吊船的浮吊作业区以及运输船，新建桥位内设置有多个墩柱和桥位临时支架，桥位临时支架的顶部开设有调节滑槽，调节滑槽内滑动设置有梁体微调装置，梁体微调装置包括滑动设置于调节滑槽内的底座、滑动设置于底座顶面上且移动方向与底座滑移方向垂直的托梁架、驱动托梁架在底座上做往复滑移运动的驱动机构，托梁架的顶面上设置有用于承托钢箱梁节段的边梁垫块。本钢箱梁吊装系统通过将钢箱梁节段分成多个梁体进行吊装，并在施工台面的顶面设置能够调整梁体位置的梁体微调装置，使得本本钢箱梁吊装系统能够用小吨位的浮吊船进行吊装施工。
