浅谈TLJ 900型架桥机的结构组成及应用

Structure Composition and Application of TLJ 900 Type of Bridge Girder Erection Machine

客运专线是我国目前投资建设的重点铁路建设项目,而TLJ 900架桥机在客运专线施工中起到了关键性的作用。TLJ 900型架桥机是针对客运专线铁路设计中桥梁体积和质量比较大、架设困难而设计的一款新型架梁设备,该机能够满足架设32、24、20m双线预应力混凝土整孔箱梁,主要结构形式为采用双导梁简支架设、采用一跨式下导梁移位过孔;同时能够满足梁体通过的空间,外形美观、合理;整机移位过孔依靠自身吊具实现,不需辅助机具。它的施工对象主要是高速铁路双线整体箱梁。

Line for passenger transportation is the important railroading project of investment of our country, TLJ900 type of bridge girder erection machine plays a key role in line for passenger transportation construction. TLJ900 type of bridge girder erection machine is a new device designed for the high speed railway bridges bulky of volume, weight of large and big constructing difficulties. It can meet the construct of 32, 24, 20 m two-lane pre-stressed concrete box girder, the main structure is the form of double guide beam simple bracket set, and uses a span of guide beam shifting, which also can meet the requirements of beam through the space, beautiful appearance, reasonability. The whole machine shifting relies on their own spreader without auxiliary equipment. The device has been used for high speed railway double line concrete box girder.
