The invention belongs to the technical field of bridge construction, and particularly relates to a multifunctional bridge erecting machine and a bridge erecting construction method.The multifunctional bridge erecting machine is characterized in that two longitudinal main spandrel girders are arranged on a front supporting device and a rear supporting device, and a front lifting crown block and a rear lifting crown block are arranged on the main spandrel girders; side fixed lifting trolleys are respectively arranged at two ends of a transverse bearing beam of the lifting crown block; the movable lifting trolleys are arranged on the section, located between the two main bearing beams, of the transverse bearing beam, and due to the fact that the three lifting trolleys are arranged on the lifting crown block, the bridge girder erection machine can lift middle prefabricated beams and side prefabricated beams, and the multifunctional bridge girder erection machine has a self-balancing function and is convenient to use. The situation that the bridging efficiency is affected due to the fact that counterweight needs to be carried out when the lateral precast beam is hoisted is avoided; in the hoisting process of the side precast beam, the multifunctional bridge girder erection machine does not need to be moved to the space outside the side edge of a bridge, so that the multifunctional bridge girder erection machine can be used for bridging under the working condition of narrow space of existing lines such as expressways and urban rails, and normal traffic operation cannot be influenced.

    本发明属于桥梁施工技术领域,尤其为一种多功能架桥机及架桥施工方法,该多功能架桥机在前支撑装置、后支撑装置上设有两条纵向的主承重梁,在主承重梁上设有前后两台起升天车,起升天车的横向承重梁的两端分别设有边侧固定起升小车;在横向承重梁上位于两条主承重梁之间区段设有活动起升小车,由于起升天车上设有三台起升小车,使得该架桥机对中部预制梁及侧方预制梁均能够进行吊装,且该多功能架桥机具有自平衡功能,避免对侧方预制梁吊装时需要进行配重而影响架桥效率;由于侧方预制梁吊装过程中,该多功能架桥机不需要移动到桥梁侧边以外的空间,所欲能够在高速公路、城市轨道等既有线路空间狭窄的工况下架桥,不会影响交通正常运行。
