Multi-dimensional turning adjustment system for hoisting steel box girder

The invention belongs to the technical field of bridge construction and in particular relates to a multi-dimensional turning adjustment system for hoisting a steel box girder. The multi-dimensional turning adjustment system comprises a deck crane top end adjusting mechanism arranged on a truss, a vertical adjusting mechanism fixedly connected with the deck crane top end adjusting mechanism and vertically arranged, and a lifting appliance end adjusting mechanism arranged at the bottom of the vertical adjusting mechanism. The the posture of a steel box girder can be adjusted rapidly so as to meet the linear precision requirement of bridge design. 本发明属于桥梁建设技术领域，尤其涉及一种用于钢箱梁吊装的多维变向调整体系，包括设置于桁架上的桥面吊机顶端调整机构，与桥面吊机顶端调整机构固定连接且垂直设置的竖向调整机构，以及设置于竖向调整机构底部的吊具端调整机构，本发明可以对钢箱梁姿态进行快速调整以达到桥梁设计线性精度要求。
