Buffer device for dismantling mid-span closure section of continuous rigid frame bridge
The invention discloses a continuous rigid frame bridge mid-span closure section dismantling buffer device which comprises a middle connecting assembly, a side connecting assembly and a carrying pole beam, the middle connecting assembly comprises a lifting rope assembly, a lifting assembly, a connecting base and a middle suspender assembly, and the upper portion of the middle suspender assembly sequentially penetrates through the connecting base and the carrying pole beam and then is fixed to the upper portion of the carrying pole beam. The lifting assembly comprises a supporting piece and a lifting wheel assembly, the lifting wheel assembly is rotationally installed on the supporting piece, and the lower portion of the lifting rope assembly is in a U shape and arranged on the lifting wheel assembly in a sleeving mode. The two side connecting assemblies are arranged on the two sides of the middle connecting assembly. Each side connecting assembly comprises a side hanging rod body, a lower supporting plate, a plurality of nut assemblies and a supporting assembly. Through cooperation of the middle connecting assembly, the two side connecting assemblies and the carrying pole beam, on one hand, the impact effect of structural system conversion is relieved to a certain degree; and on the other hand, the impact effect of sudden falling on the bridge deck crane in the closure section dismantling process is relieved.
本发明公开了一种连续刚构桥中跨合拢段拆除缓冲装置，包括中部衔接组件、侧部衔接组件、扁担梁，中部衔接组件包括吊绳组件、吊起组件、连接座、中部吊杆组件，中部吊杆组件的上部依次穿过连接座、扁担梁后与扁担梁的上部固定，吊起组件包括支撑件、吊轮组件，吊轮组件转动安装于支撑件，吊绳组件下部呈U型并套设于吊轮组件；2个侧部衔接组件设置于中部衔接组件的两侧，侧部衔接组件包括侧部吊杆主体、下支撑板、多个螺母组件、支撑组件。采用中部衔接组件、2个侧部衔接组件、扁担梁的配合，一方面，在一定程度上缓解结构体系转换的冲击作用；另一方面，缓解了合拢段拆除过程中突然下坠对桥面吊机的冲击作用。
