Large-span overweight continuous box girder jacking device
The invention discloses a large-span overweight continuous box girder jacking device, and belongs to the technical field of bridge construction, the large-span overweight continuous box girder jacking device comprises a jacking plate, a plurality of elastic supporting blocks are arranged on the upper surface of the jacking plate in an array mode, and a plurality of telescopic supporting assemblies are arranged around the elastic supporting blocks; the upper ends of the anti-skid blocks extend out of the open holes, the lower ends of the anti-skid blocks are connected to supporting plates on the inner sides of the elastic supporting blocks, the bottoms of the supporting plates are connected to the jacking plate through first springs, the supporting plates correspond to the first springs one to one, at least one anti-skid block is correspondingly installed on the upper side of each supporting plate, and the supporting plates abut against the inner wall of the outer cover through the first springs. The supporting plates are evenly arranged at intervals in the longitudinal direction of the box girder, an annular outer edge is arranged on the outer side of the upper end of the inner cylinder, and an inner ring groove used for limiting the annular outer edge is formed in the inner circumferential wall of the outer cover. According to the device, the contact area of the continuous box girder and the jacking machine can be ensured to a certain extent, and smooth construction can be ensured.
本发明公开了一种大跨径超重连续箱梁顶升装置，属于桥梁施工技术领域，包括顶升板，顶升板的上表面上阵列布置有若干弹性支撑块，围绕在弹性支撑块的四周布置有若干伸缩支撑组件；防滑块的上端从开孔伸出，防滑块的下端连接至弹性支撑块内侧的支撑板，支撑板的底部通过第一弹簧连接至顶升板，支撑板与第一弹簧一一对应，每一块支撑板的上侧至少对应安装有一块防滑块，第一弹簧将支撑板抵紧在外盖的内壁，各支撑板沿着箱梁的纵向均匀间隔布置，内筒的上端外侧设置有环形外沿，外盖的内周壁上开设有用于环形外沿限位的内环槽。本发明装置可以一定程度上保证连续箱梁与顶升机的接触面积，确保施工可以顺利进行。
