Prefabricated box girder suspender auxiliary mounting device and suspender mounting method
The invention relates to the technical field of railway bridge construction, and discloses a prefabricated box girder suspender auxiliary mounting device and a suspender mounting method.The device is used for mounting a gasket and a nut at the lower end of a suspender, the mounting device comprises a lifting appliance, the lifting appliance is connected with the suspender, the lower end of the suspender penetrates through a prefabricated box girder, and the lifting appliance is connected with a lifting beam structure; one end of the hanging beam structure extends below the lower end of the hanging rod, a jacking device is arranged on the hanging beam structure, a knob device is arranged on the jacking device, and the jacking device is used for synchronously jacking the knob device, the gasket and the nut until the nut is meshed with the internal and external threads at the lower end of the hanging rod; the knob device comprises a fixed part and a rotating part, the fixed part is fixedly connected with the gasket, and the rotating part is fixedly connected with the nut; when the nut is meshed with the internal and external threads at the lower end of the suspender, the rotating part is rotated to enable the nut to rotationally ascend along the suspender to drive the fixing part and the gasket to synchronously ascend until the gasket abuts against the prefabricated box girder. The device has the advantages of being convenient to install, efficient and safe.
本发明涉及铁路桥梁施工技术领域，公开了一种预制箱梁吊杆辅助安装装置及吊杆安装方法，该装置用于在吊杆下端安装垫片和螺母，安装装置包括吊具，吊具与吊杆相连接，吊杆的下端穿过预制箱梁，吊具上连接有吊梁结构，吊梁结构的一端延伸至吊杆下端的下方，吊梁结构上设有顶升装置，顶升装置上设有旋钮装置，顶升装置用于将旋钮装置、垫片和螺母同步顶升，直至螺母与吊杆下端内外螺纹相啮合；旋钮装置包括固定部和旋转部，固定部与垫片固定连接，旋转部与螺母固定连接；当螺母与吊杆下端内外螺纹相啮合时，转动旋转部使螺母沿着吊杆旋转上升，带动固定部与垫片同步上升，直至垫片顶住预制箱梁。本发明具有安装便捷、高效、安全的优点。
