摘要
起重机械轨道是保证起重机械安全运行的重要条件。目前的轨道检测方法,精度较低,安全性差,无法满足各类工况的检测要求。为解决检测中出现的问题,本文提出一种起重机轨道检测方法,以准直激光束为基准直线,由机械小车配备光斑位置探测装置于轨道上行走并测量各检测点的偏差数值。本文介绍了检测原理、实施方式并分析了算法,对装置样机多次试验,数据对比,评估其测试精度,并得出了此检测装置具有较强实用性的结论。
The crane rail is an important condition to ensure the safe operation of crane.The accuracy and security of current rail detection method are low and poor,and could not meet the requirements of all kinds of working conditions.In order to solve the detection problem,this article proposes a crane rail detection method,which has a linear reference by using laser beams,by mechanical car equipped with light spot position detection device to walk on the rail while measuring the deviation values of the detection.This article introduces the detection principle,the implementation method and the analysis algorithm,then designs a prototype and takes several tests,proves the practicability of the device through the accuracy evaluation and comparison.
