摘要
基于激光三角原理提出了一种用于桥门式起重机轨道检测的方法,并开发了适于此类轨道的检测系统。该系统主要包括轨道测量机器人、全站仪、三维重构计算系统。轨道测量机器人携带角隅棱镜沿轨道前进,全站仪实时追踪角隅棱镜的位置,根据记录数据重构出轨道顶面中心线的空间形状,进而计算出轨道的直线度,双轨平行度,轨道跨距等参数,以此为依据对轨道进行维修或者更换。该系统的测量精度可达±2mm,与原有检测方法相比,其检测效率提高约50%。
A bridge and trestle rail inspection system is developed based on laser triangle principle. The system consists of a railway robot, a total station instrument and a 3D reconstruction computing system. The total station instrument could trace the position of the robot walking along the railway and the central line of the railway can be reconstructed based on the measured data~ Thus parameters such railway straightness, parallelism botwecn the two rails and rail span can be worked out. These parameters can be used to determine if the rail need be repaired or replaced. The measurement accuracy of the inspection system is ＋ 2 mm and inspection efficiency increases by 50% , compared to previous inspection method.
