1 绪论

　　　矿车在煤矿井下运输中占有十分重要的地位，煤矸粘结矿车车底，是煤矿生产运输过程中存在的一个普遍问题。经常而及时地清扫矿车车箱是提高矿井轨道运输效率的重要因素。所以，清理车底的问题，在煤矿就显得尤为重要。

　　　清扫矿车车箱的主要要求是及时和干净，否则日积月累形成的煤、岩粉粘结层厚而结实，使用现有的任何清扫方法均难以立刻完全见效。

　　　清理矿车粘结物，可分为人工和机械清理、高压水射流清理等。用人工清理，劳动强度大，清车速度慢，且不符合《煤矿安全生产规定》；采用机械清理，不仅可以降低劳动强度而且清车效果好，效率高；高压水射流清理由于耗水量大，在推广上受到限制。目前国内矿车清理机械形式繁多，品种不一，而且造价较高。

1.1 国内几种矿用清车机简介

　　　70年代中后期，煤炭工业部召开了多次矿车清理机械化经验交流会，此后国内许多煤炭、冶金和化工等矿山推出了多种适合自己具体条件的清车机。这些清车机在提高运输效率和减小工人劳动强度方面都起了一定的作用。

　　　但是，由于各个矿山的具体条件不同和清车机本身的某些不完善之处使它们的发展受到了一定的限制。尽管如此，在完善和创新两方面仍然取得了不少可喜的成果。矿用清车机按照工作原理可分为振动法、电渗法、高压水射流法、机械法等，其中振动法又包括电磁振动、电动高频振动、电动低频振动、风力振动以及与翻车机笼体联动的无动力振动等；机械法又包括抓斗式、刮板式和圆盘（旋转）式等。现将几种主要的矿用清车机简介如下：

一、振动清车机

　　　振动清车机是我国使用比较早、研究比较多的一种清车机。在多年的实践和研究中，通过取长补短和采用有关的新技术，已逐步趋于完善。

　　　部分金属矿山在采用电动高频振动清车机时，吸取了电动低频振动清车机的长处，由冲击强度和刚度比较小的矿车底部或两侧改为冲击强度和刚度比较大的矿车斗缘，以延长矿车的使用寿命：用比较简单的偏心轴皮带轮取代比较复杂的振动器，使结构简单}近年来，广东某矿在清车机上采用小功率振动电机获得了成功。取得了明显的经济效益。

　　　煤炭部门所最多采用的电动低频振动清车机虽有不少优点，但缺点也较多。湘东铁矿矿务局对北京有色冶金设计研究总院为南京凤凰山铁矿设计的低频振动清车机作了一些改进，由原来比较复杂的单独安装简化为与翻笼固定在一起，由原来需要摘钩、每次只能清理一辆矿车改为不需要摘钩，每次能清理两辆矿车。东北工学院和北京有色冶金设计研究总院所作的电测应力分析表明，翻笼安装这种清车机对其强度影响是不大的，因而不必另外增加静笼的结构强度。为了向安装在翻笼上的清车机电机供电，在煤矿上采用集电环联动机构之后，一些金属矿山又推出了电磁给电装置和电动推杆给电装置。

二、电渗清车器

　　　电渗法清理矿车是在外电场的作用下，以水为介质在矿车与粘结物之间形成一层水膜，使粘结物与车壁脱离而达到清理矿车的目的。这种方法具有无噪声、无粉尘、不损坏矿车等优点。但是由于耗电较多，故它仅适用于存积物含水量较高的矿车。该方法起初在徐州权台煤矿使用。后来，铜陵铜山铜矿和龙游黄铁矿等金属矿山也陆续采用，并取得了较好的效果。

三、高压水射流联合机械截齿清理机

　　　该种矿车清理装置的工作机理包括高压水射流清理和机械截齿清理两部分。

　　　高压水射流清理：高压水经喷嘴喷出后形成具有一定动能的高压水射流，当作用于矿车粘结物时，将对其进行切割和冲刷作用，使有一定粘结力的非固结性粘结物迅速脱落，同时高压水射流冲人粘结物的缝隙和孔洞后，则产生高压水楔作用，使粘结物的缝隙和孔洞不断扩展断裂，而破碎脱落。

　　　机械截齿清理：利用螺旋分布的截齿对坚硬粘结物的切割作用，使粘结物快速与矿车分离。

结构组成

　　　该种清理装置主要由可三维空间移动的门式组合机架、高压泵站、电控系统和截齿可伸缩清理滚筒等组成，其中清理滚筒是实现清理作业的直接执行部件。

　　　截齿可伸缩清理滚筒由圆柱形筒体、切割截齿、高压水射流喷嘴、旋转密封等组成，筒体上螺旋分布着12个切割截齿和6个高压水射流喷嘴，每个切割截齿能沿其旋转直径方向在50 mm的范围内伸缩移动，以适应变形矿车的清理。高压水射流喷嘴随截齿螺旋均匀分布，泵站提供的高压水，经高压管路和旋转密封进入圆柱形筒体的中心孔，由各喷嘴喷出而形成高压水射流，实现对粘结物的冲刷、冷却润滑截齿和灭尘的作用。

四、机械清车机

　　　机械清车机利用电动机带动清扫器在矿车车箱内转动清除车底的粘结物。清扫器有金属刷式、盘式、滚筒式、螺旋割刀式等几种。清车机的横向行走部、纵向行走部、截割部都是由许多机械零件组合起来的，因此，结构笨重、操作复杂、维修量大。此外，使用这种清车机还需二次翻卸，费工费时，效率不高。有关煤矿虽作了一些改进，但效果不明显。吉林通化铜矿曾研制成一台由刷洗头、制动轴、减速器和电动机等组成的车箱清扫器。其纵向行走部分是一个装有四个小轮的小车，能沿轨道前进或后退。清扫器底座与小车铰接，能绕铰点上下和左右摆动。最近，这类清车机有了新的进展。由洛阳工学院等单位研制的Qw3型机械铣切卧式三吨矿车清车机通过了技术鉴定。据称，适应性强；能利用部分现有配件和标准件，便于加工；与同类产品相比成本低、省人、省力、省电、经济效益好。

The gaugue felt on the bottom of the coal car is one of the common problems on the process of coal production and transportation. To clean the compartment of mine car frequently and promptly is a significant way of raising the efficiency of mine pit rail haulage. No matter the quality of coal, the size composition and water content as well, due to the bad environment of coal production and the vibration in the process of transportation, there always has some coal and other materials left which was very easy to cake on the bottom of the mine car after unloading. If we do not clean these remaining coal and rock meal soonly, they would be heavier and solider, which would increase the weight of mine car so that decrease the effective volume of it. Then it would not only affect the transportation ability of mine car directly and make the intense condition of the transportation system, but also increase the waste of electric power, and even make substantial difficulty in starting the spacial vehicle while transporting the electrical machinery truck. So cleaning the bottom of the mine car become espectially important. This design add the hydraulic system on the basis of traditional cleaning machine for mechanical mine car. It changes clutch control into the hydraulic control, and is added the multi-channel electromagnetism cross valves which controlled the all round migration of cleaning machine and the movement of the rocking shaft. It also overcomes the shortcoming that the friction control cannot clean the remainings on the bottom of mine car due to its splitting.Keyword: Pure car machine; Hydraulic pattern; Mineral car目录1 绪论1.1 国内几种矿用清车机简介11.2 液压矿车清车机的特点41.3 液压式双圆盘截齿矿车清车机简介41.4 与原机械式矿车清扫机的比较61.5 矿车清车机设计的目的62设计总体方案确定2.1 方案的制定原则72.2 本设计方案的规划72.3 设计方案的内容总结93 截割部设计3.1 截割头的设计要求113.2 截割头的设计113.3 截割臂的设计123.4 仰俯液压缸的设计154 驱动系统的设计计算4.1 清车机动力的选择254.2 驱动方案的确定264.3 马达的选型274.4 减速箱的设计计算294.5 链传动的设计计算415 行走部的设计5.1 纵向行走驱动液压缸的设计计算485.2 横向液压缸的设计计算576 液压泵站的计算与设计 6.1 液压泵参数的计算与选型636.2 电动机的选型646.3 液压控制阀的选择656.4 液压辅件的选择67 6.5 液压泵站的结构设计726.6 液压系统的维护保养与相关注意事项72结论 78参考文献 79附录1 液压系统图81附录2 矿车清车机所用液压元件一览表 82附录3 液压式双圆截盘矿车清车机总图83附录4 液压式双圆截盘矿车清车机传动系统图84翻译部分英文原文85中文译文91致谢 95翻译部分 The new tramcar Ahealthy market means that underground truck and LHD markers are enjoying high order levels, with new models and technology also coming .in the LHD sector, several new models are already on the market from firms including EJC, Fermel, Rham Equipment and Schopf (WME Oct & Nov 2004), while Atlas Copco intends to launch at least one new design in 2005 possibly an St14.But it is the truck sector that is the most active right now with renewed emphasis on power to weight ratios right through the payload range The latest models are taking advantage of advances in diesel technology by fitting more powerful engines and allowing better speeds on steep ramp hauls .The impact of this is significant, as higher speeds mean lower cycle times and offer major gains in productivity, even allowing reductions in fleet sizes.At the top of the payload scale competition is now particularly fierce. Sandvik Tamrock is certainly pushing the boundaries with its Toro 60, a three axle truck with a rigid chassis and a 60 tonne capacity. This Cummins-powered truck offers a good power to weight ratio and a payload advantage over Caterpillars AD55 and atlas Copos MT5010 that Sandvik Tamrock says should allow mines to trim fleet size, especially over longer ramp hauls. sandvik Tamrock expects the Toro 60 to take back some of the market claimed by Cats successful AD55,with its 55 tonne payload. However Atlas Copco is fighting back against both Caterpillar and Sandvik tamrock with yet another upgrade to its MT5010 truck, providing a power increase from 488-597kw/650-800hp. The new Cummins Qsk19 diesel boosts the MT5010s power to weight ratio from 5.27-6.5kw/tonne, allowing it to reclaim ground over the AD55 and Toro60, despite their larger payload. Atlse Copco also says that driveline problems which afflicted earlier truck designs have long since been eliminated. The company points out that MT5010 is a successful design with units operating I Australia recording speeds of 14kph on 1:10 ramps, despite having 23,000 hours on the clock. Evaluating which of these three trucks offers the highest productivity could only be achieved by detailed study(and perhaps require testing), possibly with a different result depending on the nature of the specific mining application. The revised MT5010 has a higher power to weight ratio than either the AD55 or the Toro 60 but these trucks have bigger payloads of 55 and 60 tonnes respectively. The machine that best suits a given mining operation may be due to a number of basic factors such as haul distance and ramp gradient as well as ventilation infrastructure, ambient temperature and even material type. Overall though the customer will be the winner, with the latest large Atlas Copco, Caterpillar and Sandvik Tamrock trucks all offering much better productivity and reliability than was ever available to the 50+tonne class before.The same dort of power to weight ratio gains can be seen further down the truck payload range. Atlas Copco, Caterpillar, Dux, EJC, MTI and Zanam legmet have all fitted more powerful diesels to trucks with payloads in the 12-30tonne range,with similar benefits to those seen at the top of the capacity scale. For example, one Canadian mine replaced its earlier generation 16 and 17 tonners with newer 20 tonners,which offer short travel times on ramp, despite their increased payload and this has resulted in a substantial productivity gain overall. That the new generation of engines produce more power from similar outer dimensions is important, as they give a better payload/litre of fuel burned. However the cleaner emissions have added benefits, with cost advantages to mine ventilation requirements.In general, the new small-mid sized trucks themselves are externally similar to previous models, but are fitted with stronger drivetrains and axles to cope with the additional power (WME Oct2004&WME Nov 2004). Small detail changes like extended oil life or filters with replaceable elements make identifiable benefits to service costs. While the basic designs of these updated trucks remains similar, the better drivelines and new generation diesels mean that the machines require less maintenance are more reliable and are considerably cheaper to run.Self-driveAutomation is still on the agenda with regard to LHDs and trucks, with the many benefits being shown at those mines that have taken the plunge and opted for this technology. These is still progress to be made with regard to orders but Caterpillar and Sandvilk Tamrock are both pushing hard to sign up customers for their LHD(and truck)automation systems, MINEGEM and Automine respectively. At the moment only Codelco is using the full Automine automation system at the Pipa Norte and Diablo Regimiento zones of its EITeniente copper mine in Chile. But DeBeers and Sandvik TAmrock are developing a system for the Finsch mine in South Africa. And while Caterpillar has yet to notch up a commercial sale for MINEGEM, the technology is being used for production at the northparkes and Olympic Dam mines in Australia.There are a lot of similarities in the way MINEGEM and Automine work, with laser equipment mounted onboard the LHDs. These scan the tunnels ahead of the machines as they tram, picking up changes in the tunnel profile and allowing the machine to recognize its position in milliseconds. The lasers update tunnel maps continuously to, resulting in large volumes of date shuttling back and forth constantly. Cats MINEGEM system operates on a wireless LAN infrastructure with an 11 Mbps capacity. Sandvik TAmrocks Automine system requires similar broadband communicational capabilities. Both MINEGEM and Automine are controlled by conventional and readily available computing hardware, while a good deal of the components is standard off-the-shelf items selected for their ability to cope with the tough mining cycle. With these technologies, one operator can supervise the running of up to three LHDs that run more or less autonomously, with the only manual input being for the bucket loading part of their operating cycle. Caterpilliars MINEGEM is a package built up of several layers and this allows customers to select the separate components they require. The tactical layer of MINEGEM provides automatic steering for an LHD and prevents it from colliding with the walls of the tunnel or against other vehicles. The operator fills the bucket and selects forward or reverse, with the system providing automated tramming and bucket dumping. The strategic layer is more complex as this integrates the operation of up to three LHDs, oversees their operation and has higher level planning capabilities. It is the strategic layer that is in chare of traffic control functions, so that multiple cycles can be scriptedfor blending ores from different drawpoints for instance, with the overall benefit of increasing production efficiency.Safety is improved as the operators can be situated away from where the machines are running (they dont even have to be in the mine at all and in theory, could be sitting in an office on the other side of the world). Moreover, the machines require less maintenance and have lower running costs as gearchanges are made at optimum times, engines are not over-revved, there is less wheel-spin and the risk from collisions with tunnel walls of other machines is all but eliminated.However, the complete Automine and MINEGEM technologies are not inexpensive and suit applications in purpose-built mine areas (or even mines).The automated equipment runs in parts of the mine that are separated from other operations and with personnel access carefully controlled. There are however comparatively few large(and/or new)mines with the sort of block caving or sublevel caving applications that best suit this sophisticated full automation technology and can justify the investment. As a result, Caterpilliar and Sandvik Tamrock (separately) identified a need for less sophisticated systems that offer many of the same operating benefits, while being substantially less costly. By opting for just the tactical layer of MINEGEM (called Co-Pilot), a mining firm can introduce an effective and comparatively low-cost technology for single LHD automation. And CO-Pilot comes with a manual over-ride, allowing it to be used as a conventional remote control if/when required. In this respect, Sandvik Tamrock has a broadly similar product in the shape of its Automate system, which is also designed for single LHD automate and has equivalent control specifications.With Automation or Co-Pilot, mines can introduce single LHD automation into applications where conventional remote control systems are used at present. The advantage of this is that single machines can benefit from the automated tramming, without the expense of the complete machine automation package(or the inherent changes to infrastructure and mine layout). Both Caterpilliar and Sandvik Tamrock point out that this technology has huge potential with firms using conventional remote control and will be of particular benefit at mines with high incidences LHD collision damage. And, as anyone who has ever operated a radio-controlled car can attest, it can be difficult to judge distances between a moving machine and its surroundings from a distance. The single automation equipment will take away this risk of collisions and make substantial reductions in machine downtime and repairs, as well as boosting productivity. A study commissioned by Caterpillar from Australian body STEM shows that replacing conventional remote controls with simpler single LHD systems would provide payback times of three years(and even less in some instances), while providing productivity gains of up to 37%.For the moment, mining firms seem reluctant to invest in full LHD automation due to the expense and complexity of the technology. But with the production and cost benefits offered by Cats MINEGEM Co-Pilot and Sandvik Tamrocks Automate system for single LHD automation in existing mines, that situation could well change soon.Russian firm MOaZ builds two underground trucks, the 7405-9586 for narrow operating conditions and the more conventional 7529, both of which have 22 tonne payloads. The 7405-9586 weighs 19.5 tonnes unladen, has a canopy as standard, is powered by a JMZ-238KM2 diesel rated at 140kw and measures 2.9m wide for use in narrow access areas. As this model has 2WD it can cope with 9maximum slopes and best suits flat hauls or tunneling applications, offering a maximum speed of 40 kph. The 7529, weighs 24 tonnes unladen, features 4WD and has a more powerful JMZ-238BN2 engine delivering 190 kw, allowing use on steeper ramps. This machine also has a top speed of 40 kph and is equipped with an enclosed cab as standard. Both the 7405-9586 and 7529 trucks can be fitted with Deutz engines if required.German firm Paus built two tractors for Kali & Salz that tow pallets on trailers using a gooseneck connection. The vehicles are powered by 176 kw Deutz BF6M1013 engines. These offer payloads of up to 30 tonnes and are used to carry equipment, spare parts and materials underground, though product haulage is still by truck. Paus also has a number of loaders now operating at mines in Russia, with a number of engineering coming in a well from Australia. These are from engineering firms carrying out feasibility studies and are not expected become equipment orders immediately, but the firm is confident that these will translate into actual deals. The company adds that it is now receiving interest in the novel undercutting type machines, of which it built 15 units for operations in Belarus. In addition, Paus is building a number of ditch cleaning machines for Norilsk Nickel in Russia. These are based around a small mine locomotive, with an excavator boom that allows the machine t clear the dewatering ditches running alongside the tracks.中文译文新型矿车良好的市场意味着地下卡车和LHD制造者正在享有一流的水平，同时新模式和技术不断涌向市场。在LHD行业，来自EJC，FERMEL，RHAM EQUIPMENT和SCHOPF公司的新模式已出现在市场上，与此同时，ATLAS COPCO公司预计最迟在2005年开始从事一种新型设计-ST14。但是，在卡车行业，现在最活跃的事情是重新重视功重比和有效载荷的变化。最新模式通过安装更大功率的发动机和允许在陡的斜坡行程中有较好的运行速度，充分利用了柴油机在技术上的发展。这种作用是显著的，速度愈高意味着循环周期愈短，获得的生产效率愈高，甚至允许减小规模。在有效载荷极限方面的竞争，现在是特别的激烈。SANDVIK TAMROCK正推出TORO60、三轴带有固定底座和容量60T的卡车，这种功率的卡车，可以提供比CATERPILLAR公司AD55和ATLAS公司的MT5010更好的功重比，以至于SANDVIL TAMROCK公司说这种设备允许矿井改变它的规模，特别是长的斜坡行程的地方。SANDVIK TAMROCK 期望TORO60可以夺回由有效载荷是55T的CAT公司的有成效的AD55占领的市场，然而，ATLAS COPCO公司用另一种改进型的可提供功率488-597KW/650-800HP变化范围的MT5010卡车同CATERPILLAR 和SANDVIK TAMROCK两家公司作斗争。新型QSK19柴油机使MT5010的功重比从5.27KW/T增加到6.5KW/T，这使它重新获得由AD55和TORO60占领的市场，ATLAS COPCO公司说尽管AD55和TORO60有很大的有效载荷，但困扰卡车设计者的路线问题，很长时间才被消除。根据在澳大利亚的速度14KPH 1：10斜坡上的单元操作，公司指出，MT5010是一项非常成功的设计，尽管耗时23000H。对这三种卡车，哪种能提供更高的生产率的评估，只有通过细节的研究才能实现，不同的结果依赖于特定矿井应用的性质。虽然AD55有55T的有效载荷和TORO60有60T的有效载荷，但与AD55和TORO60相比，改进型MT5010有更高的功重比。某种机器最适用于某种给定的矿井操作可能是因为一些基本因素，比如：行程距离、坡度、通风设施、周围环境的温度，甚至材料类型。不过总体上说，顾客是赢家，与以前的50T级可获得的生产率和可靠度相比，最新大型的ATLAS 、COPCO CATERPILLAR 和 SANDVIK TAMROCK公司生产的卡车全都可以提供更好的生产率和可靠度。卡车有效载荷变化不久，同种功重比的获得即可看到。ATLAS COPCOC、ATERPILLAR、 DUX、EJC、MTI和ZANAM LEGMET 公司安装更大功率的柴油机在卡车上，这允许有效载荷在12-30T范围内变化，类似成效在容量范围上也能看到。例如，一加拿大矿井，用新型20T取代了它早期的16T-17T，它在斜坡上费时较短，尽管只增加了有效载荷，但大体上仍提高了生产率。与同表面尺寸的发电机相比，新一代发电机提供更大的功率是重要的，因为燃料燃烧时，它们能给更多的能量。不管怎样，排放物愈清洁，利润愈高，通风设施成本愈低。一般来说，新中小型卡车表面上类似于以往的模式，只是安装了更坚固的驾驶装置和便于应付额外功率的轴。一些小细节的改变，如增加汽油的寿命或取代过滤器，可以识别对服务成本的优势。这些更新过的卡车的基本设计仍保持类似性，好的路线和新一代柴油机意味着机器需要较少的维修，拥有更高的可信赖度和相当低的运行成本。自动驾驶对于LHD和卡车来说，自动化一直是重要事情，对于这项技术已有许多优势呈现在那些矿业面前等待他们做出决定和选择。定单一直在增加，尽管如此，CATERPILLAR和SANDVIK TAMROCK两家公司一直对为了他们各自的自动化系统、MINEGEM和自动采矿的签约顾客施压。此时此刻，仅CODELCO公司正在应用全自动系统，在CHILE的EITENIENTE矿的PIPA NORTE 和DIABLE REGIMENTO区域。但是DEBEERS 和SANDVIK TAMROCK 公司正在为了在南非的FINSCH矿井应用而研发一种新的系统。此时，CATERPILLAR公司已获得MINEGEM的商业化买卖权，此技术正在应用于澳大利亚的NORTHPARKES和OLYMPIC DAM矿井中。MINEGEM和AUTOMATE之间有许多类似的地方，在LHD上都安装有激光装置。当卡车运行时，这些激光装置可以扫描机器前面的隧道，接收隧道侧面轮廓的变化，然后允许在几秒内对它的位置做出辨别。激光装置根据连续前进后退所得大量的数据更新隧道地图。CATERPILLAR公司的MINEGEM系统运行于容量是11MPS的无线LAN基本设施上。SANDVIK TAMROCK公司的自动采矿系统需要广泛的沟通能力。MINEGEM和自动采矿由系统和可快速获得的计算机硬件控制，同时有许多组成部分是普通的已有的项目，这些项目选择它们应付棘手循环问题的能力。在这些技术支持下，一位操作者可以管理三台正在运行的LHD
