Small-radius curve descending type segment assembly bridge girder erection machine
The invention discloses a small-radius curve descending type segment assembly bridge girder erection machine which comprises two sets of pier-side stand columns symmetrically arranged outside a pier. The main supporting legs are arranged on the pier-side stand columns and connected to the outer sides of the piers in a clamped mode; the shifting trolley is arranged on the main supporting legs; the bridge erecting machine has the beneficial effects that in the construction process, the dead weight of the bridge erecting machine and the dead weight of an erected bridge are not pressed on a bridge deck and a bridge pier any more and are connected to the main supporting legs in a pressed mode, the dead weight load is directly transmitted to the bearing platform through the main supporting legs, and no beam surface load exists in erected beams and through holes; the problem of comprehensive waste of bridge design due to the fact that temporary construction load borne by a bridge and a pier is far larger than normal operation load when an existing ascending type segment assembly bridge girder erection machine is used for erecting beams and passing holes is solved. Meanwhile, due to the fact that the bridge girder erection machine adopts the foldable main girder system, the defects of an existing descending type segment assembly bridge girder erection machine are overcome, and the adaptability of the bridge girder erection machine to large-span and small-radius curve bridges is improved.
本发明公开了一种小半径曲线下行式节段拼装架桥机，包括对称设置在桥墩外部的两组墩旁立柱；设置在墩旁立柱上的主支腿，主支腿卡接在桥墩外侧；设置在主支腿上的移位台车；本发明所具有的有益效果为：施工过程中架桥机自重及所架桥梁自重不再压在桥面和桥墩上，而是压接在主支腿上，由主支腿直接将自重荷载传递至承台，架梁和过孔均无梁面荷载，解决目前已有上行式节段拼装架桥机在架梁及过孔时桥梁及桥墩承受临时施工荷载远大于正常运营荷载而造成的桥梁设计综合浪费现象；同时因为本发明架桥机采用可折式主梁系统，解决了目前已有下行式节段拼装架桥机的不足之处，拓展了其对较大跨度及小半径曲线桥梁的适应能力。
