摘要:

某黄河公路桥50 m跨架桥机是原有30 m跨架桥机改造而成,为确定改造后的实际承载能力,针对架桥机在空载向前延伸及吊装大梁运行两个工况状态下的受力性能进行了静载试验研究,根据架桥机不同工况与最不利位置,详细分析了架桥机的变形性能及不同杆件的受力性能,得出悬臂延伸工况下B支座拉杆屈服、架桥机变形过大,架桥机接头质量尚待改进等主要结论,为架桥机的进一步改进提供了依据.

Abstract:

In order to determine the actual bearing capacity after the transformation, the static load test study was carried out for the force performance of the bridge erector under the two working conditions of no-load forward extension and lifting girder operation, according to the different working conditions and the most unfavorable position of the bridge erecting machine, the deformation performance of the bridge erecting machine and the force performance of different members were analyzed in detail, and the main conclusions such as the yield of the B support tie rod under the cantilever extension condition, the deformation of the bridge erecting machine was too large, and the quality of the bridge erecting machine joint needed to be improved. It provides a basis for the further improvement of the bridge erecting machine.
