摘　　要：以某小型多功能履带式液压挖掘机为基础,设计开发了一种遥控抢险工程车,完成了工程车的研制。介绍了抢险工程车各部分的组成、结构以及工作原理,主要分为遥控系统、液压系统、行走机构和工作装置4个部分。对遥控抢险工程车行走机构和工作装置进行了改进设计,通过遥控发射系统可以远程无线控制抢险工程车工作,避免现场操作的危险。远程控制的电液比例先导控制系统具有响应快、布线灵活,可以实现集成控制并可以与计算机接口等优点,实现了工程车行走、转向、翻越障碍物和转台的旋转,工程车机械手的升降、伸缩、旋转和机械手开闭等各种动作的遥控操纵。在多种工作条件下进行了遥控抢险工程车样机性能测试试验,试验表明遥控抢险工程车的各种动作及工作性能符合设计要求,结果表明开发的工程车各性能指标达到了预期要求。On the basis of a compact multi-functional hydraulic crawler excavator, a remote controlled emergency engineering vehicle was developed. Its research and production were fulfilled. Composition, structure and work principle of every part, mainly remote control system, hydraulic system, travel mechanism and work attachment, of the emergency engineering vehicle are described. Its travel mechanism and work attachment were designed with improvement. The vehicle can work under wireless remote control by remote transmiting system to avoid field operation danger. The remote-controlled, electro-hydraulic proportional pilot control system features prompt response and agile wiring so that advantages such as integrated control and computer connection can be realized. Remote control of various operation such as traveling, turning, barrier-clearing and work platform slewing of the engineering vehicle as well as the lifting, telescoping, rotating and on/off of its manipulator are all accomplished. Performance test of its prototype was conducted under different work conditions and it shows that various operations and work performance of the engineering vehicle meet design requirements. The results demonstrate that every performance index of the developed engineering vehicle reaches the demands expected.
