Suspended pouring and suspended splicing combined crane for steel-concrete mixed variable cross-section continuous box girder bridge
The invention discloses a suspension pouring and suspension splicing combined crane for a steel-concrete mixed variable cross-section continuous box girder bridge, and relates to the field of bridge construction equipment. The hoisting mechanism is movably mounted on the spliced double-layer track beam, the position of the hoisting mechanism can be adjusted through movement of the double-layer track beam, the crane does not need to be moved forwards by one beam section when one beam section is hoisted in the cantilever splicing construction process of the bridge steel beam section, the bearing pressure of the end of the steel beam section is relieved, and the construction efficiency is improved. The situation that linear control is inconvenient due to too large load bearing and too much downwarping of the ends of the steel beam sections is prevented, and the bridge splicing construction quality can be improved; the bottom end of each section of track beam is provided with the supporting frame supported on the bridge floor, the spliced track beams can be supported, so that the mounting stability of the track beams and the stability of a hoisting mechanism during hoisting work are improved, and the weight of a crane is dispersed to the bridge floor through the multiple supporting frames, so that the stress of the bridge is dispersed, and the safety of the bridge is improved. And the bridge supporting points are prevented from being extruded and deformed due to overlarge stress caused by single-point supporting.
本发明公开了一种钢‑混混合变截面连续箱梁桥悬浇悬拼联合吊机，涉及桥梁施工设备领域。本发明中起吊机构移动安装于拼接式的双层轨道梁上，能通过双层轨道梁移动调节起吊机构的位置，而无需在桥梁钢梁段悬拼施工过程中吊装一个梁段就将吊机整体前进一个梁段，减轻了钢梁段端部的承重压力，防止钢梁段端部承重过大下挠过多而不便于线形控制，能提高桥梁拼接施工的质量；且在每节轨道梁的底端均安装有支撑于桥面的支撑架，能对拼接后的轨道梁进行支撑，从而提高轨道梁安装的稳定性以及起吊机构吊装工作时的稳定性，且通过多个支撑架将吊机的重量分散到桥面，使得桥梁受力分散，防止单点支撑使得桥梁支撑点受力过大而被挤压变形。
