摘要
主索鞍是悬索桥主缆系的重要受力构件,特大悬索桥主索鞍鞍体结构体积质量大,构造复杂,一般为铸焊式结构,其制作涉及到铸造、焊接、机加工等专业。以南京长江四桥主索鞍鞍体为例,研究主索鞍鞍体焊接和机加工主要技术工艺,对制作过程的难点、重点进行分析,通过采取相应的工艺控制措施,取得了优良的产品质量,可以为特大型悬索桥主索鞍鞍体的制作提供参考。
The main cable saddle is the important stress member of the main cable system for a suspension bridge, which features large structure, heavy mass and complicated structure, generally a cast-welded structure, its manufacture involves casting, welding and machining etc. This paper takes Nanjing Yangtze River Fourth Bridge main cable saddle body for example, the main technique and process of welding and machining were studied and the difficulty and key points of manufacture process were analyzed. By taking appropriate process control measures, excellent product quality was got, which provided some reference for the super large suspension bridge saddle body manufacture.
