Automatic bolt type pushing device and pushing method
The invention belongs to the technical field of steel box girder pushing construction, and particularly relates to an automatic plug pin type pushing device and method.The device comprises a pushing support, a jacking hydraulic jack, a horizontal hydraulic jack, a steel plug pin and a crank mechanism, and when a steel box girder is pushed, the steel plug pin is inserted into a set position through the jacking hydraulic jack; and then the steel box girder is pushed forwards by a certain distance through the horizontal hydraulic jack, and all pushing operation of the steel box girder is achieved through repeated operation. The problems that in a traditional pushing device and method, the processes of jacking, advancing, falling and retreating are repeated, the construction process is tedious, and in the repeated process, the position deviation of a main beam is likely to be generated are solved, the working difficulty of jacking and pushing of the steel box beam is greatly reduced, the construction efficiency is improved, the jacking and pushing precision of the steel box beam is guaranteed, and the construction period is shortened. And except that the first fixing bolt and the second fixing bolt need to be operated manually, other steps can be automatically carried out, and construction convenience is improved.
本发明属于钢箱梁顶推施工技术领域，具体涉及一种自动插销式顶推装置及顶推方法，装置包括，顶推支架、顶升液压千斤顶、水平液压千斤顶、钢插销、曲柄机构，顶推钢箱梁时，先通过顶升液压千斤顶使钢插销插入设定位置，然后通过水平液压千斤顶将钢箱梁向前推进一定距离，反复操作，实现钢箱梁的全部顶推作业。本发明解决了“传统顶推装置和方法中重复进行顶升、前进、下落与回退过程，施工过程繁琐，并且在反复的重复过程中，易产生主梁位置偏差”的问题，大大降低了钢箱梁顶升推进的工作难度，提高了施工效率，保证了钢箱梁的顶升推进精度，除了固定栓一和固定栓二的操作需要人工外，其他步骤可自动化进行，提高了施工的便利性。
