Fabricated bridge construction device
The invention relates to the technical field of assembly type bridges, and particularly discloses a fabricated bridge construction device which is characterized in that a track groove is formed in a pier, a step is formed in one side of a main beam, and a pin hole is formed in the end, close to the main beam, of the step; when the main beam is dragged to a predetermined position through a tractiondevice, a sliding type positioning device corresponds to the pin hole, the hydraulic cylinder is started to extend, the hydraulic cylinder drives the sliding sleeve to move upwards and support a deflection rod to deflect, a positioning block corresponds to the step to abut against the side face and the bottom face of the main beam, and the sliding sleeve drives the connecting rod to move so thatthe rear end of a supporting lever can be lifted. And a pin at the front end of the supporting lever is inserted into the pin hole to realize positioning. By means of traction type construction, limitation of terrains and the like is eliminated, the main beam can be temporarily fixed or released in the construction process by arranging the sliding type positioning device, and the problems of installation precision and the like caused by sliding or deformation of the main beam are solved.
本发明涉及装配式桥梁技术领域，具体公开了一种装配式桥梁施工装置，所述桥墩上放置有轨道槽，所述主梁的一侧开设有台阶，所述台阶靠近主梁一端位置开设有销孔，当主梁通过牵引装置牵引到预定位置，所述滑动式定位装置与所述销孔对应，启动液压缸伸长，所述液压缸带动所述滑动套筒向上移动并支撑所述偏转杆偏转，所述定位块与所述台阶对应将所述主梁的侧面和底面抵紧，所述滑动套筒带动所述连杆动作后使支撑杠杆后端提升，将支撑杠杆前端的销钉插入所述销孔内，实现定位。本发明通过牵引式施工，消除了地形等限制，通过设置滑动式定位装置，还可以在施工过程中临时固定或者释放主梁，防止主梁滑移或者变形带来的安装精度等问题。
