摘    要:对高空作业车的结构和工作原理进行分析,在此基础上建立变幅和回转液压系统故障树,并对变幅和回转液压系统回路关键点参数进行在线监测。建立变幅和回转液压系统故障树,对故障产生的原因进行定性分析。利用传感器、单片机、液晶显示器等监测回路关键点参数变化,通过监测参数对液压系统故障进行定量分析。通过故障树和监测结果,快速排除高空作业车在工作过程中的故障。该方法可以帮助维修人员快速查找液压系统故障,为其他液压系统故障诊断的研究提供参考。

关 键 词:高空作业车  液压故障树  在线监测  传感器

Abstract:The structure and working principle of the aerial working platform is analyzed, on the basis of the establishment of amplitude and slewing hydraulic system fault tree. The amplitude and slewing hydraulic system key parameters are monitored online. An amplitude and slewing hydraulic system fault tree is established and the qualitative analysis of the causes of failure. Use of sensor, microcontroller, liquid crystal display monitor circuit key parameters, such as change, through monitoring the parameters for quantitative analysis of the hydraulic system failure are analyzed. Through the fault tree and monitoring results, quickly ruled out the fault in the process of overhead working truck at work. The method can help maintenance personnel to quickly find hydraulic system fault, provide a reference for others researching hydraulic system fault diagnosis.
Keywords:aerial working platform  hydraulic system fault tree  on-line monitoring  sensor
