Steel box girder erecting device for highway bridge design
The invention relates to the technical field of steel box girder erection, in particular to a highway bridge design steel box girder erection device which comprises an embedded steel plate, a triangular supporting plate is fixedly connected to the upper surface of the embedded steel plate, a stand column is fixedly connected to the outer surface of the triangular supporting plate, and a supporting rod is fixedly connected to the outer surface of the stand column. A supporting table is arranged at the top of the supporting rod, an adjusting mechanism is fixedly connected to the upper surface of the supporting table, and a supporting mechanism is fixedly connected to the upper surface of the adjusting mechanism. A first compression spring and a second compression spring jointly act to buffer impact force generated when the steel box girder body is lowered, when a large amount of gas in a gas guide hole is compressed when flowing through a vent hole, reverse thrust generated by the compressed gas to a cushion block can secondarily buffer the impact force generated when the steel box girder body is lowered, and the impact force generated when the steel box girder body is lowered is reduced. And the placing table is prevented from being damaged due to too fast lowering when the steel box girder body is hoisted.
本发明涉及钢箱梁架设技术领域，具体涉及一种公路桥梁设计钢箱梁架设装置，包括预埋钢板，所述预埋钢板的上表面固定连接有三角支撑板，所述三角支撑板的外表面固定连接有立柱，所述立柱的外表面固定连接有支撑杆，所述支撑杆的顶部设置有支撑台，所述支撑台的上表面固定连接有调节机构，所述调节机构的上表面固定连接有支撑机构，本发明通过设置缓冲组件对钢箱梁体下放时的冲击力进行缓冲，第一压缩弹簧以及第二压缩弹簧共同作用对钢箱梁体下放时的冲击力进行缓冲，当导气孔内大量的气体在流经通气孔时被压缩，被压缩的气体对垫块产生的反向推力可对钢箱梁体下放时的冲击力进行二次缓冲，防止吊装钢箱梁体时因下放过快导致放置台损坏。
