Steel box girder pushing structure for bridge construction
The invention discloses a steel box girder pushing structure for bridge construction, thereby overcoming the defects that in the construction process of a cable-stayed bridge, steel box girder pushingdeviation rectifying operation is inconvenient, and the deviation rectifying effect is poor. The pushing structure comprises a plurality of temporary piers, a steel box girder and pushing assembliesinstalled on the temporary piers. Two pier columns are arranged on each temporary pier, two supporting columns used for supporting the steel box girder are arranged on each pier column, one pushing assembly is installed between every two supporting columns on each pier column, and each pushing assembly comprises a lifting oil cylinder, a lifting base, a translation oil cylinder, a pushing base anda translation base. A deviation rectifying guide seat is arranged on the lower surface of the steel box girder; outwards inclined guide plates are arranged on the two sides of the lower end of the deviation rectifying guide seat; a deviation rectifying guide wheel is installed on the translation base, a pressing seat is installed at the upper end of the translation base, a reset spring is installed between the pressing base and the translation base, two deviation rectifying ejector rods which are obliquely arranged outwards from top to bottom are hinged to the pressing base, deviation rectifying ejector rods are rotationally installed on the translation base, and the outer ends of the two deviation rectifying ejector rods are attached to the left side wall and the right side wall of the deviation rectifying guide seat respectively.
本发明公开了一种用于桥梁施工的钢箱梁顶推结构，旨在解决斜拉桥施工过程中钢箱梁顶推纠偏操作不便，纠偏效果不佳的不足。该发明包括若干临时墩、钢箱梁、安装在临时墩上的顶推组件，临时墩上均设有两墩柱，墩柱上设有两用于支撑钢箱梁的支撑柱，墩柱上两支撑柱之间均安装一顶推组件，顶推组件包括升降油缸、升降座、平移油缸、顶推座、平移座；钢箱梁下表面上设有纠偏导座，纠偏导座的下端两侧均设有向外倾斜设置的导板，平移座上安装纠偏导轮，平移座上端安装压座，压座和平移座之间安装复位弹簧，压座上铰接两由上往下向外倾斜设置的纠偏顶杆，纠偏顶杆转动安装在平移座上，两纠偏顶杆外端分别贴合在纠偏导座左右两侧壁上。
