介绍SSJ900型整机过隧架桥机的主要技术参数、设计理念及整机构造、作业方式、关键技术和创新点。该机主梁采用连接方式为仿平行四边形构架的两跨连续梁结构,起重桁车为可降高、缩宽的门式起重机,依靠主梁及起重桁车的几何尺寸变化,实现整机过隧作业功能。该机方案先进、合理,操作可靠、安全,作业灵活,具有较高的性价比。该机的成功研制和应用对国产大吨位运架设备的开发具有一定参考价值。
Describes the main technical parameters, design concept and structure, operation mode, key technologies and innovations of SSJ900 complete machine tunneling machine. The main beam of the aircraft adopts a two-span continuous beam structure with a parallelogram quadrangular structure, and the lifting crane is a gantry crane which can be lowered and widened. By virtue of geometric variations of the main girder and the lifting crane, Machine cross-tunneling function. The aircraft program advanced and reasonable, reliable operation, safety, flexible operation, with a high cost. The successful development and application of this machine has a certain reference value for the development of domestic large-tonnage transport equipment.
