Continuous rapid pushing system for overweight large-span bridge
The invention discloses a continuous and rapid pushing system for an overweight large-span bridge. The continuous and rapid pushing system comprises a bridge supporting structure, a beam body, a pushing driving device, a sliding supporting device, a guiding deviation correcting device and a monitoring control unit. The bridge supporting structure comprises a permanent pier and a temporary steel supporting pier. The pushing driving devices are symmetrically arranged on the two sides of the beam body and comprise gears and racks, and the beams are continuously pushed to advance through meshing of the gears and the racks. The sliding supporting device comprises a sliding plate which forms a friction pair with the composite steel plate at the bottom of the beam body. The guiding deviation correcting devices are symmetrically arranged on the two sides of the beam body and push the beam body to be within a safety value range when the beam body deviates transversely. The monitoring control unit controls the pushing driving device to stably move the beam body to a designed bridge site; jacking oil cylinders arranged at the tops of the permanent bridge piers jack the beam body to finish beam falling operation of beam body stress system conversion. According to the rapid pushing system, the purpose of continuous, rapid and safe one-time cross-line construction in-place of a large-span and large-tonnage bridge body can be achieved.
本发明公开了一种超重大跨度桥梁连续快速顶推系统，包括桥梁支撑结构、梁体、顶推驱动装置、滑动支撑装置、导向纠偏装置以及监测控制单元。桥梁支撑结构包括永久桥墩及临时钢支撑墩。所述顶推驱动装置对称设于梁体两侧，包括齿轮及齿条，通过齿轮与齿条啮合，从而连续推动梁体行进。所述滑动支撑装置包括滑板，其与梁体底部的复合钢板组成摩擦副。导向纠偏装置对称设于梁体两侧，在梁体横向偏移时将其推到安全值范围内。监测控制单元控制顶推驱动装置将梁体平稳移动至设计桥位；永久桥墩顶部设有的顶升油缸将梁体顶起，完成梁体受力体系转换的落梁作业。本发明的快速顶推系统，可实现大跨度、大吨位桥梁梁体连续快速安全一次跨线施工就位的目的。
