Walking operation platform for maintaining steel box girder arch bridge
The invention relates to a walking operation platform for maintaining a steel box girder arch bridge, which adopts a movable steel-encased arch cage type tool, a hanging bracket supporting system is of a steel truss structure and stretches across a vault, four upright posts of a hanging bracket are respectively provided with two rollers, two I-shaped steel rails laid along the vault are clamped by the rollers, a cage system consists of a U-shaped cage ladder and a cage, and the cage ladder is connected with the hanging bracket supporting system. The cage is composed of a liftable cage ladder and a separable bottom hanging basket, and an electric hoist, a steel wire rope and a depended wheel are arranged in the cage; the lifting cage is arranged below the lifting frame, the U-shaped cage ladder is connected with the lifting frame through a cage ladder hanging rod, four groups of steel wire ropes on the lifting frame are connected with four electric elevators fixed on the cage ladder, and the cage ladder can be freely lifted by arranging the electric elevators and the steel wire ropes inside. Under the condition of open traffic, large-area maintenance coating or other operation can be carried out on the through type or half-through type steel box girder arch bridge, the influence on traffic safety and traffic organization is reduced, and the high safety risk of common climbing equipment is reduced.
本发明涉及一种钢箱梁拱桥维修用行走作业平台，采用可移动的外包钢拱笼式工装，吊架支撑系统为钢桁架结构，横跨拱顶，吊架四立柱各装有二只滚轮，并通过滚轮夹持沿拱顶上铺设的二条工字钢轨道，吊笼系统由U型的笼梯和吊笼组成，吊笼由可提升式笼梯和可分离式底部吊篮构成，内设电动提升机、钢丝绳、靠轮；所述吊笼设于吊架下方，U型的笼梯与吊架通过笼梯挂杆连接，其中，吊架上四组钢丝绳与固定在笼梯上四个电动提升机连接，通过内设电动提升机、钢丝绳能实现笼梯自由提升。本发明可在开放交通的情况下，对下承式或中承式钢箱梁式拱桥大面积维修涂装或其他作业，减少对行车安全和交通组织的影响，减少普通登高设备具有的高安全风险。
