摘要
悬挂式单轨交通轨道梁架空建设,不利于轨道梁的检测维修。分析轨道梁日常检修需求及指标要求,介绍了外部巡检小车结构设计、缺陷检测方案、安全系统与控制系统的工作过程。外部缺陷巡检小车可实现轨道梁外部表面锈迹与四角主焊缝裂纹的全自动检测与载人维修作业,降低检修人力成本、提高检测效率与准确率。目前外部巡检小车的设计方案已经成熟,将逐步开展测试试验。
Suspension-type mono-rail transportation track beams are built overhead,which is not conducive to the inspection and maintenance of track beams.This paper analyzes the daily maintenance needs and index requirements of the rail girders,and introduces the structural design of the external inspection trolley,the defect detection scheme,the working process of the safety system and the control system.The external defect inspection trolley can realize the fully automatic detection and manned maintenance of the rust stains on the external surface and cracks in the main welds of the four corners of the rail beam,which can reduce the maintenance labor cost and improve the detection efficiency and accuracy.At present,the design scheme of the external inspection trolley has been matured,and test trials will be carried out gradually.
