Jacking and retreating device and method of combined type deck crane for bridge cantilever construction
The invention relates to the technical field of bridge construction, and discloses a combined type bridge deck crane jacking and retreating device for bridge cantilever construction, which comprises a jacking system for jacking a base of a bridge deck crane upwards, a back pressure system for preventing the bridge deck crane from overturning in the jacking process, and a crane walking system, the crane walking systems are symmetrically arranged on the two sides of the deck crane base in the longitudinal direction. The whole crane is jacked up synchronously in a balanced mode through the four jacks, and then the walking track is laid at the bottom of the crane. And then, the crane is pulled back to the poured bridge top plate along the track through the jack. The method solves the problem that the subsequent construction is affected due to the fact that the bridge floor composite crane cannot be dismantled in time in the process that the cantilever construction of the water-area-crossing bridge is propelled towards the midspan. And after the crane retreats to the bridge floor, the crane can still be normally used for hoisting materials.
本发明涉及桥梁施工技术领域，公开了一种桥梁悬臂施工用复合式桥面吊机顶升后退装置，包括用于将桥面吊机的底座向上顶起的顶升系统、用于防止桥面吊机顶升过程中倾覆的反压系统和吊机走行系统，所述吊机走行系统分别沿纵向对称设置在桥面吊机底座的两侧；本发明采用四台千斤顶同步平衡地将整个吊机顶起，随后在吊机底部铺设走行轨道。接着，利用千斤顶沿轨道将吊机拉回至已浇筑的桥梁顶板上。这一方法解决了跨水域桥梁悬臂施工向跨中推进过程中，因无法及时拆除桥面复合式吊机而影响后续施工的难题。当吊机回退至桥面后，仍可正常使用进行物料吊装。
