Self-walking operation platform for construction of bottom of cable-stayed bridge and installation method
The invention discloses a self-walking operation platform for construction of the bottom of a cable-stayed bridge and an installation method, the self-walking operation platform comprises a movable truss and walking mechanisms arranged on the two sides of the movable truss, the movable truss is hung on the two sides of a bridge girder, and the walking mechanisms are movably connected with the two sides of the bridge girder; the movable truss comprises a platform truss and supporting trusses arranged at the two ends of the platform truss, and the walking mechanisms are arranged at the tops of the supporting trusses. A construction reserved space exists between the platform truss and the bottom of the bridge, and a limiting mechanism making contact with the side edge of a main beam of the bridge is arranged on the supporting truss. Compared with the prior art, through the arrangement of the limiting mechanism, in the moving process of the movable truss, the top and the side edge of the bridge make contact with the walking mechanism and the limiting mechanism at the same time, it is ensured that the movable truss does not transversely move in the walking process, and it is ensured that the gravity center of the operation layer is located in the middle of the operation layer while the operation layer is supported; and the operation layer has better stability in the moving process, so that the operation layer has better safety performance.
一种用于斜拉桥梁底施工的自行走操作平台及安装方法，包括移动桁架和设置于移动桁架两侧的行走机构，移动桁架挂接于桥梁主梁的两侧，且行走机构与桥梁主梁的两侧移动连接；所述移动桁架包括平台桁架和设置于平台桁架两端的支撑桁架，行走机构设置于支撑桁架顶部；所述平台桁架与桥梁底部之间存在施工预留空间，支撑桁架上设有与桥梁主梁侧边相接触的限位机构；与现有技术相比，通过限位机构的设置，移动桁架在移动过程中，桥梁的顶部和侧边同时与行走机构和限位机构相接触，确保移动桁架在行走过程中不出现横移，在对操作层进行支撑的同时，确保操作层的重心位于操作层中部，使得操作层在移动过程中具有更好的稳定性，从而具有更好的安全性能。
