【摘要】 我国蕴藏丰富的天然煤炭资源,是世界上生产煤炭最多的国家,但也是消费煤炭最多的国家。在如此大的煤炭消耗量面前,煤矿开采过程中的安全问题也越来越突出,受到煤矿企业的高度重视。其中,对矿山企业危害较大的不安全因素以煤矿水灾害危害最大,它不仅破坏了煤矿企业正常的生产和建设,还给企业带来了严重的物质、经济损失,危害到了煤矿工人的生命财产安全。本文从我国煤矿建设和生产过程中经常遇到的水灾害入手,以煤矿井下排水的大环境为背景,给出了煤矿斜井井下常用的四种排水方案：并列组合式潜水电泵用于小型矿井抢险排水、斜井深井泵排水、斜井潜水泵群排水、斜井卧式离心泵排水；提出了本文所要深入研究的课题——井下应急排水车行走机构液压系统；在文中说明了研究内容和技术路线,即设计种响应迅速、流量大、现场安装时间短、复杂路面通过性好,可实现快速救援的煤矿井下履带式水陆两用应急排水车为了更好的研究履带式水陆两用应急排水车的液压系统,文中首先利用仿真软件对所设计的液压系统进行稳定性及整体性分析。这将有效的弥补当今应急救援设备存在的不足,为预防矿井水灾害提供有效的保障,对于维护国家和人民生命财产安全提供重要支撑；然后确定了液压系统的基本方程、传递函数以及相关参数,并且在MATLAB/SIMULINK仿真软件中建立闭式回路的控制系统的模型,分析了其动态性能；接着在AMEsim软件中建立履带式应急排水车液压系统的模型,用此模型对液压系统的稳定进行了分析,证明了系统设计的可行性；最后利用ADAMS动力学软件和AMESim控制软件对液压泵控系统进行了联合仿真,检验了所设计的液压系统的合理性。更多还原

【Abstract】 Our country has rich natural coal resources, the production of coal is the most in the world, also the consumption of coal is the most. In the face of so much consumption of coal,safety problems in the process of mining is more and more outstanding, it has been attached great importance. Among them, the largest harm to the mining enterprise is flood hazard, it can’t only damage the coal mine enterprise’s normal production and construction, but also bring serious physical, economic losses, the harm to the lives and property of the coal mine worker safety.The article is basic from the our country coal mine construction and production often encountered in the process of water disaster, to mine water environment as the background, gives four kinds of inclined shaft of coal mine underground drainage scheme:the parallel combination of submersible electric pump used in small coal mine rescue and dewatering shaft, deep well pump, submersible pump in drainage well group drainage horizontal, inclined shaft centrifugal pump; puts forward the subject of intensive research--downhole emergency drainage running mechanism hydraulic system; in this paper describes the research contents and technical route, namely to design a fast response, large flow, field installation time is short, the complex pavement through the good, can realize the rapid rescue for coal mine underground track amphibious dual-purpose emergency drainage vehicle.In order to better research tracked amphibious emergency drainage vehicle hydraulic system, firstly, by using the simulation software of hydraulic system stability and overall analysis. This will effectively compensate for the emergency rescue equipment shortages, for the prevention of mine water disasters to provide effective protection, for the maintenance of safety of country and people life property to provide important support; Then determine the hydraulic system of the basic equation, transfer function and related parameters, and the simulation software MATLAB/SIMULINK to establish the close loop control system model, analyzes its dynamic performance; then in AMEsim software in building crawler emergency drainage vehicle hydraulic system model, use this model on the stability of hydraulic system were analysed, proved the feasibility of system design; finally, using ADAMS dynamics software and AMESim control software for the hydraulic pump control system of joint simulation, inspection of the design of the hydraulic system.更多还原
