【摘要】 新型接触网检修作业车是用于电气化铁路施工和维护的动力车辆,被广泛地应用于电气化铁路上部设备的安装、维修及日常检修、保养。同时,它也可用做牵引车,与其它工程车联挂进行接触网和路轨的检修和保养。本论文所设计的新型接触网检修作业与国内现有的作业车相比,具有牵引功率大、运行速度快、低速作业时静压驱动等特点。随着我国经济的飞速发展,轨道交通运输也在高速、重载、客运专线等方面实现飞跃发展。随着电气化铁路发展,尤其是在铁路高速等技术的政策实施后,使线路上在线的车辆密度、通过能力有了很大幅度的提高,因此,用来维护保养电气化铁路设备的“天窗”时间变得越来越短。这就促使电气化铁路施工及维护的工程机械也向着高速、高性能、高可靠性方向转变,然而现有装备的接触网检修作业车已经相对落后,其更新换代势在必行。新型接触网检修作业车是由兰州交通大学下属的测控技术研究所以及兰州立盛达铁路新技术有限责任公司共同开发研制的。本论文对新型接触网检修作业车的状态监测系统进行了设计。可归纳为七大部分:第一部分,介绍状态监测技术的国内外发展现状;第二部分,通过对监测系统的功能需求进行分析,以及系统指标的确定,在遵循监测系统设计原则的条件下初步制定监测方案;第三部分,通过对新型接触网检修作业车动力系统、传动系统、制动系统及液压系统工作原理的分析,确定需要监测的参数及测点的位置;第四部分,介绍了监测系统硬件电路的设计及其元器件选型;第五部分,介绍了PLC监测程序以及MT508TV5型触摸屏人机界面的设计;第六部分,搭建实现平台,调试监测系统;第七部分,介绍了监测系统装车时的防干扰措施和司机室驾驶平台的设计。本文作者经过调研、分析及设计等过程,最终完成了满足新型接触网检修作业车要求的监测系统的设计。更多还原

【Abstract】 The repairing vehicle for overhead contact line equipment is a kind of powered vehicle which is used in electrified railway construction and maintenance.It is widely used in equipment installation,maintenance and daily inspection of overhead contact line equipment.In addition,it can be used as a tractor to drag other vehicles for repairing overhead contact line equipment.Compared with the existing repairing vehicle for overhead contact line equipment in China,the new one designed in this thesis has larger traction power,higher speed and hydraulic drive at low speed etc.With the rapid development of our country’s economy,railway transport also has grown in high-speed,heavy haul and railway line for passenger traffic.Especially after the technical policy about high-speed,heavy haul has been implemented with the development of electrified railway,the density of vehicles and the traffic capacity on line have been greatly improved,while the "skylight" time for maintenance becomes shorter,which prompts engineering machinery used for the electrified railway to be improved towards highspeed and good performance.However,the exiting repairing vehicles for overhead contact line equipment have been relatively backward,the upgrading is imperative.The new repairing vehicle for overhead contact line equipment has been developed by Measuring&Controling Technology Institute of Lanzhou Jiaotong University and Lanzhou Lishengda Railway New Technology Co.,Ltd.In the thesis,the status monitoring system of the new repairing vehicle is designed.The thesis can be grouped into seven major parts.In the first part,the developments of the status monitoring technology at home and abroad are described.In the second part,based on the functional requirement analysis and the indicators analysis,initial monitoring plan is drawn up in compliance with the conditions of the monitoring system design principles.In the third part,through analysis on power,transmission,brake and hydraulic system of the new repairing vehicle,the parameters to be monitored and the positions of measuring points are determined.In the fourth part,the design of monitoring circuit and selection of components are introduced.In the fifth part,the design of the monitoring program of PLC and HMI of touch screen MT508TV5 are described.In the sixth part,experimental platform and monitoring system debugging are described.In the seventh part,the anti-interference measures and the design of platform in driver’s are introduced.After investigation,analysis and design,finally,we have completed the design of the monitoring system which meets the requirements of the new repairing vehicle for overhead contact line equipment.更多还原
