随着我国高速铁路建设的迅猛发展，我国高速铁路施工工况越来越呈现出多样性。在多山地区，特别是在桥隧相连的路段进行架桥、转场施工及中心城市附近有双线并行路段施工时，目前国内广泛应用的辅助导梁式架桥机、桁架式架桥机等一系列运架分离式架设设备需要作十分复杂的拆装（部分解体）或改装过程。极大地延缓了山区高速铁路的建设施工进度。

In view of the explosive growth in China’s high-speed railway construction, the conditions of construction are getting more and more diversified. During the bridge erecting and transfer of construction sites in the mountainous regions, particularly in the bridge and tunnel connecting sections, and during the construction at the road sections where there are parallel double lanes in the vicinity of urban center, the dismantling (partial disintegration) or modification process of a series of widely used separable typed carrying and erecting equipments, such as the auxiliary guide girder bridge erecting machines, truss-typed bridge erecting machines etc. can be very complicated. This has greatly delayed the high-speed railway construction progress in the mountainous regions.     

本课题设计一种高速铁路运架一体架桥机，是一种新型的铁路预制梁架设工程机械。它集吊梁、运梁、架梁于一身，改变了传统的提、运、架的桥梁施工工艺，比原有的架桥机、运梁车有明显的优势。特别是在隧道比较多的路段，可以省去拆卸架桥机的工作，只需简单地改装主支腿，即可完成桥梁架设施工。可简化传统的复杂架桥工法，提高架桥效率高和安全性能。

This topic designs a bridging machine that incorporates the carrying and erecting functions together; this is a new type of machinery for the construction of  erecting railway precast beams. It incorporates hoisting, carrying and erecting the beams all in one, transforming the traditional bridge construction process, and it has an obvious advantage over the original bridging machines and beam transporting vehicles. Particularly in the road section where there are many tunnels, it can spare the trouble of dismantling the bridging machine; all it needs to complete the bridge erection construction is to simply modify the main leg supports. It can simplify the complicated bridge erecting engineering and enhance the efficiency and safety.      

并应用三维软件进行结构设计，创建三维实体装配模型，并进行运动仿真分析，验证结构设计的合理性。本课题设计的关键部位在于对原有架桥机的支腿部分以及主梁部分进行改进，增加了起吊天车机构，能够使架桥机自动完成不同长度梁的架设。

This topic adopts 3D software to conduct the structural design and creates a 3D physical assembly model, so as to analyze the movement simulations and validate the rationality of the structural design. The critical part of this design is the improvement of the supporting legs and main beam of the original bridge erecting machine and the addition of a lifting crane mechanism, so that it can automatically accomplish the erection of various different lengths of beams.

Abstract

　　随着我国高速铁路建设的迅猛发展，我国高速铁路施工工况越来越呈现出多样性。在多山地区，特别是在桥隧相连的路段进行架桥、转场施工及中心城市附近有双线并行路段施工时，目前国内广泛应用的辅助导梁式架桥机、桁架式架桥机等一系列运架分离式架设设备需要作十分复杂的拆装（部分解体）或改装过程。极大地延缓了山区高速铁路的建设施工进度。
With the rapid growth of high-speed railway construction in our country, the working condition of highspeed railway construction becomes more and more diverse. In mountainous districts, especailly in the sections where bridges and tunnels are connected, when bridges are under construction, or it is unavoidable to build railways by changing sites, or there are parallel sections under construction near central cities, it entails very complicated disassembling process for the currently widely used navagational beam bridge builders and truss formed bridge builders in our country. All the dismounting, remodification and partial dismantling of equipment greatly deters the construction schedule of mountainous high-speed railway construction.

With the rapid development of high-speed railway construction in our country, the working condition of high speed railway construction in our country is increasingly showing a diversity. Bridge in mountainous area, especially in tunnel sections connected to the bridge and ferry construction and near the central city have double parallel road construction, the current domestic widely used settled auxiliary guide beam, truss type settled and a series of the gantry separate erection equipment need to be very complex disassembling (partial dissolution) or modification process. Greatly delayed the mountainous high speed railway construction of the construction schedule. This subject designed a kind of high speed railway transport aircraft settled a body, is a new kind of railway precast beam erection construction machinery. It combines crane beam, the beam and frame beam, changed the traditional bridge, transport, construction technology, than the original erector integrates, transporting girder vehicle has obvious advantages. More roads, especially in the tunnel can be settled without disassembly work, simply refitting the main leg, to complete the bridge erection construction. Simplifies the traditional complicated bridge method, and improve the bridge with high efficiency and safety performance. Structure design and application of 3 d software, creating 3 d entity model, assembly and motion simulation analysis, validate the rationality of structure design. This topic design of key parts is settled the original leg part and the main girder section was improved, increasing the lifting crane, can make the different length of beam erection settled automatically
