Support-free pushing device and method suitable for large span and long distance
The invention provides a support-free pushing device and method suitable for a large span and a long distance, and relates to the field of bridge construction equipment and method. The support-free pushing device comprises an integrated horizontal pushing device and an independent jacking oil cylinder. According to the structure of the integrated horizontal pushing device, a pushing device is arranged on a fixedly-arranged base, the pushing device is connected with a pushing sliding base so as to drive the pushing sliding base to slide, a deviation rectifying sliding base is connected with the pushing sliding base in a sliding mode, a deviation rectifying device is fixedly arranged on the pushing sliding base, the deviation rectifying device is connected with the deviation rectifying sliding base so as to drive the deviation rectifying sliding base to slide, and the sliding direction of the deviation rectifying sliding base is perpendicular to the sliding direction of the pushing sliding base. By adopting the scheme that the integrated horizontal pushing device and the jacking oil cylinder are independent of each other, the overall height of the whole pushing equipment can be reduced, the beam falling difficulty is reduced, the structure of a fixed pier is omitted, the size of the whole pushing system is reduced, and arrangement at the top of a bridge pier is facilitated.
本发明提供一种适于大跨径长距离无支架的顶推装置和方法，涉及桥梁施工装备及方法领域，包括集成的水平顶推装置和独立的顶升油缸；所述集成的水平顶推装置的结构为：固设的底座上设有推进装置，推进装置与推进滑座连接，以驱动推进滑座滑动，纠偏滑座与推进滑座滑动连接，在推进滑座固设有纠偏装置，纠偏装置与纠偏滑座连接，以驱动纠偏滑座滑动，纠偏滑座的滑动方向与推进滑座的滑动方向垂直。通过采用集成的水平顶推装置和顶升油缸互相独立的方案，能够降低整个顶推设备的整体高度，减小了落梁的难度，也取消了固定墩的结构，减小了整个顶推系统的体积，便于在桥墩顶部布置。
