Pushing device for small steel box girder construction
The invention discloses a pushing device for small steel box girder construction, which comprises a lifting device for lifting a steel box girder and a bridge support for placing the lifting device and the steel box girder, a support guide rail is fixedly mounted on the bridge support, and the extension length of the support guide rail is consistent with the displacement distance required for mounting the steel box girder; a main frame body used for installing a lifting device is arranged on the supporting guide rail, and the main frame body and the supporting guide rail are in transmission connection through a driving gear and a rack which are meshed in a matched mode. According to the scheme, in the installation process of the steel box girder, the steel box girder can be installed at a constant and stable moving speed, repeated contact between the steel box girder and the pier is avoided, and the phenomenon that the steel box girder and the pier are damaged due to excessive collision is reduced; and meanwhile, the deviation adjusting mechanisms capable of synchronously running are arranged on the main frame body, so that deviation adjustment and deviation correction are carried out in the stable moving process of the steel box girder, and the accuracy of the mounting position of the steel box girder is guaranteed.
本发明公开了一种用于小型钢箱梁施工的顶推装置，包括用于顶升钢箱梁的抬升装置以及用于放置抬升装置和钢箱梁的桥梁支架，桥梁支架上固定安装有支撑导轨，支撑导轨的延伸长度与钢箱梁安装所需的位移距离一致；支撑导轨上设置有用于安装抬升装置的主架体，主架体与支撑导轨之间通过适配啮合的驱动齿轮和齿条传动连接；本方案能够使钢箱梁在安装的过程中，保持匀速稳定的移动速度进行安装，避免了钢箱梁与桥墩的多次接触，减少钢箱梁与桥墩之间出现过度碰撞受损的现象；同时，通过在主架体上设置能够同步运行的调偏机构，使钢箱梁在稳定移动的过程中，进行调偏纠偏，保障了钢箱梁安装位置的精准度。
