Vertical-longitudinal connecting device for bridge girder erection machine
The invention discloses a vertical-longitudinal connecting device for a bridge girder erection machine, which comprises a connecting base used for being connected with a middle supporting leg of the bridge girder erection machine, an upper roller set used for being in contact connection with the upper surface of a lower chord of a main guide beam of the bridge girder erection machine, a lower roller set used for being in contact connection with the lower surface of the lower chord of the main guide beam, a beam locking assembly used for preventing the main guide beam from sliding and a drivingassembly, wherein the driving assembly is used for driving the upper roller set and the lower roller set to move; the upper roller set, the lower roller set, the beam locking assembly and the drivingassembly are all installed on the connecting base; and the upper roller set is used for driving the middle supporting leg to move forwards or backwards when the middle supporting leg is suspended, and the lower roller set is used for driving the main guide beam to move forwards to cross the span when the middle supporting leg supports the main guide beam. The upper roller set is in contact connection with the lower chord of the main guide beam, so that the middle supporting leg moves forwards and backwards when the middle supporting leg is suspended, the forward moving step of the middle supporting leg is simplified, the span crossing speed of the bridge girder erection machine is increased, and the construction cost is saved; and meanwhile, the problem of mismatching of the rigidity of the middle supporting leg and the main guide beam is avoided.
本发明公开了一种架桥机用竖纵连接装置，包括用于与架桥机的中支腿连接的连接基座、用于与架桥机的主导梁下弦杆的上表面接触连接的上滚轮组、用于与主导梁下弦杆的下表面接触连接的下滚轮组、用于防止主导梁滑移的锁梁组件以及驱动组件，驱动组件用于驱动上滚轮组和下滚轮组运动；上滚轮组、下滚轮组、锁梁组件以及驱动组件均安装于连接基座上；上滚轮组用于在中支腿腾空时带动中支腿前移或后退，下滚轮组用于在中支腿支撑主导梁时带动主导梁前移过跨。设置上滚轮组与主导梁下弦杆接触连接，实现了中支腿腾空时中支腿的前移和后退，简化了中支腿前移步骤，加快架桥机过跨速度，节约了施工成本；同时避免了中支腿与主导梁的刚度不匹配问题。
