目前,铁路建筑行业使用的架桥机只能满足在千分之二十坡道上进行的箱梁架设任务。为了保证辅助导梁式架桥机能在千分之三十的坡道上进行箱梁架设,文章利用结构设计理论,按照中心受压杆件力学模型对架桥机前支腿进行了结构稳定计算,同时对后支腿的制动力后驱动力进行了检算,并提出了改造建议,确保架桥机的安全可靠。
At present, the erecting machines used in the railway construction industry can only meet the requirements of erecting girder girders on the 20th of a thousandth of a meter. In order to ensure the auxiliary girder bridge girder erection of box girder on the 30th of a thousandth hill, the article uses the structural design theory to calculate the structural stability of the erecting outrigger of the erecting machine according to the mechanical model of the center compacted bar, At the same time, the driving force of the rear leg braking force was checked, and the suggestion of reconstruction was put forward to ensure the safety and reliability of the bridge erecting machine.
