Integrated prefabricated bridge dismantling machine and prefabricated bridge dismantling method
The invention relates to the technical field of bridge construction, in particular to an integrated prefabricated bridge demolition machine and a prefabricated bridge demolition method. The integratedprefabricated bridge demolition machine comprises a demolition machine main beam, a plurality of supporting legs, a plurality of intelligent crown block systems and a cutting device. The top of the plurality of supporting legs are arranged on a second rail, and the bottom is in snapped connection with the prefabricated bridge, and the plurality of supporting legs can slide on the second rail andthe prefabricated bridge. The multiple intelligent crown block systems are arranged on the first rail, can slide on the first rail in the longitudinal direction of the bridge and are detachably connected with the supporting legs. Due to the fact that the bottom faces of the supporting legs and the prefabricated bridge are temporarily fixed, the intelligent crown block system cannot move backwards,friction force between the intelligent crown block system and the first rail can drive the dismantling machine main beam to walk in the longitudinal direction of the bridge, and the cutting device can be used for cutting the upper structure and the lower structure of the prefabricated beam to be dismantled respectively. Therefore, The integrated prefabricated bridge demolition machine has the advantages that the construction operation plane is concentrated, the period is short, the input amount of a temporary structure is small, and the cost is low.
本申请涉及一种一体化预制桥梁拆除机及预制桥梁拆除方法，涉及桥梁施工技术领域，其包括拆除机主梁、多个支腿、多个智能天车系统和切割装置，多个支腿顶部设在第二轨道上，底部与预制桥梁卡接，且可在第二轨道和预制桥梁上纵桥向滑动，多个智能天车系统设在第一轨道上且可在第一轨道上纵桥向滑动，并与支腿可拆卸连接；由于支腿底面与预制桥梁被临时固定，使得智能天车系统无法向后移动，因此，智能天车系统与第一轨道间的摩擦力会驱动拆除机主梁沿纵桥向走行，并可使用切割装置分别对待拆除预制梁的上部结构和下部结构进行切割，因此，本申请具有施工作业面集中、周期短、临时结构的投入量较少和成本较低的优势。
