The invention discloses a hoisting device for arch rib sections of a steel box basket arch bridge, and belongs to the technical field of bridge engineering. The number of the adjustable lifting hook connecting blocks is two, two position adjusting sliding grooves are formed in the top of the carrying pole beam, and each adjustable lifting hook connecting block is connected into the corresponding adjustable lifting hook connecting block in a sliding mode. According to the hoisting device for the arch rib section of the steel box basket arch bridge, the distance between the two adjustable lifting hook connecting blocks is controlled by the position adjusting mechanism to be correspondingly adjusted according to the size of the single arch rib section, so that the position of a force application point of a hoisting machine corresponds to the single arch rib section, the stability in the hoisting use process is guaranteed, and the use effect is improved; according to the hoisting device for the arch rib section of the steel box basket arch bridge, the bottom of the single arch rib section is wrapped by the bottom wrapping belt, so that the gravity of the single arch rib section can not completely act on the hoisting cable, the gravity is allocated to the carrying pole beam, additional risks in the using process are reduced, and the safety in the using process is improved.
本发明公开了一种钢箱提篮拱桥拱肋节段的吊装装置,属于桥梁工程技术领域,包括:扁担梁;可调吊钩连接块,其设有两个,扁担梁的顶部开设有两个调位滑槽,每个可调吊钩连接块均滑动连接于每个可调吊钩连接块内。该钢箱提篮拱桥拱肋节段的吊装装置,通过调位机构控制两个可调吊钩连接块之间的距离根据拱肋单节段的大小进行相应的调整,使吊装机施力点的位置与拱肋单节段对应,保证吊装使用过程中的稳定,提高使用效果,该钢箱提篮拱桥拱肋节段的吊装装置,通过兜底带将拱肋单节段的底部进行包裹,可以使拱肋单节段的重力不完全作用于吊装索上,将重力分摊至扁担梁上,减小使用过程中的额外风险,提高使用过程中的安全性。
