摘要
阐述了我国盾构机再制造的发展现状并指出了我国盾构机再制造发展的不足与挑战,综述了盾构机主轴承、刀具刀盘、液压系统、减速机、螺旋输送机等关键部件的损伤形式及目前常用的再制造修复方法。分析了激光熔覆、热喷涂、冷喷涂、冷焊等增材修复技术在盾构机再制造方面的潜能和优势,最后展望了盾构机再制造的发展趋势。
The development situation of shield machine remanufacturing in China was expounded,and the development shortages and challenges were pointed out.The damage forms and the repair methods of key parts of shield machines,such as main bearing,cutter and cutter head,hydraulic system,reducer,screw conveyer were summarized.The potential and advantages of additive repairing technologies such as laser cladding,thermal spraying,cold spraying and cold welding in shield machine remanufacturing were analyzed.The future development trends of shield machine remanufacturing were finally provided.
