摘 要
往复式给煤机安装在煤仓下口处，在煤矿井下生产中，设置一定容量的煤仓对于保证消峰平谷和高产、高效是十分必要的。
往复式给煤机由机架、底板（给煤槽）、传动平台、漏斗、闸门、托辊等组成。当电机开动后经弹性联轴器、减速机、曲柄连杆机构拖动倾料13°的底板在辊上作直线往复运动，煤均匀地卸到其他设备上。它可以有效地提高工作面采掘设备的利用率，充分发挥运输系统的潜力，保证连续均衡生产。但是，煤仓窜仓事故在我国煤矿经常发生。窜仓事故常造成设备严重损坏，井下停产，当窜仓煤量较大时，还会阻塞巷道，造成运输巷通风不畅，引起瓦斯爆炸等事故。
为了防止和降低煤矿井下煤仓窜仓造成的设备损坏、人员伤亡、阻塞巷道和影响生产等危害，设计了一种用于往复式给煤机的防窜仓装置，从而为煤仓窜仓的防治提供了一个新的途径。

The expanded series reciprocation type stoker should satisfythe following request. 1) satisfies the large-scale mine pit productivity the request Along with the our country coal mine pit unceasing expansion,the hour productivity also is increasing, for example: The well is 2.4million t/a, 3 million t/a. 4 (XI ten thousand t/a mine pit, hourproductivity separately for 42 h, 928t/h, 1238t/h. The mine pit hourproductivity increase, the request enhances the stoker theproductivity. At present, the mine pit mine shaft raw coaltransportation more and more many uses the adhesive tape conveyer, inother words, the mine shaft used the stoker the link to increase.Although may use many small models stoker jointly to arrange satisfiesthe big productivity the request, but arranges many stokers to need toexpand Weighed the room, the increase project investment moreover manyarrangement, the system reliability reduces, the noise increases, hasthe problem the probability also relatively to increase. brings thecertain trouble to the service. Loads a car the system in the useadhesive tape conveyer, is in the ground production system uses stokermost places, moreover the request gives the coal ability quite to bebig. Loads a car the system if uses Electric vibrator for the material machine,not only increased has loaded a car moreover the noise very to behighly big. Installs the large-scale reciprocation type stoker, notonly causes the hour productivity to increase, moreover also forloaded a car the system equipment shaping to provide has been biggermay choose the scope. 2) loads the belt type necessary with the host well bottom of the well(beat) the conveyer The main well bottom of the well loads the belt type (beat)the quota conveyer type bottom of the well charging gear developmenttendency, lists as the coal key scientific research item, when thequota conveyer idling speed loading is requested for the coalequipment ability 801) above ttb, the existing K series stoker cannotmeet this requirements. Although also may use for the material strobe material, but for the material strobe for estimated easily the rawcoal moisture, the granularity influence, causes for the materialnon-uniformity. But the large-scale reciprocation type stoker maysatisfy this request large-scale reciprocation types deceive the coal machinestructural style characteristic We through carry on the analysis to the former stokerinvestigation, has carried on the thorough computation to thestructure pattern, to the essential stress spot like tank, the doubleconnecting rod, the base held the roller and so on to carry on thestress analysis, carried on the examination computation using thefinite element principle. Altogether has following fivecharacteristics. 1) entire machine uses the frame Themselves to be possible to unload thetype Because considered the mine shaft transportation theconvenience and the mine shaft industry and mining limit, entiremachine uses a minute writing style, moreover considered the mineshaft welding inconvenient, uses the bolt vice- joint, the side bar toconsider the external drum the possibility and the endophragm wear theneed, lays down in the flank Reinforced inside Lining, strengthened thewhole rigidity and the intensity. 2) increases Daoban the guidance and the blocking In makes the reciprocal motion under Daoban to additionallybuild several groups of requests rollers wheel, on the one handchanges Daoban the sliding friction for to roll the friction, reducedthe attrition, on the other hand also causes Daoban the rigidityenhancement. Moreover, for prevented Daoban is transporting Moves in the process to have runs the leaning phenomenon, inDaoban two sides installments guidance wheel. 3) uses the hyperbolic trough drive type The stoker drive uses the hard tooth face reduction gear,ordinary plug shaft coupling (but non- fluid strength coupler), doubleoutput shaft form, like this, not only reduced the cost moreover tocause the unilateral Axis radial direction load only is the bottomsurface thrust force one half, is carried the condition bigimprovement, moreover, further enhanced the stability which Daobanmoved. 4) carries on the optimization to the Daoban structure Formerly K series stoker plate strobe, the material had manyproblems in shipping, for estimated could not enhance the key also layin this. Therefore, we have carried on the optimization to Daoban,designs for the steps and ladders, Not only caused the material process load to enlarge, moreoverthe Daoban itself intensity also obtained further enhances. 5) changes the fan strobe for the manual plate strobe Controls expects how many the key to be decided by the strobe,the strobe always uses the fan structure in the former K series, butdiscovered from the field use, the fan strobe and the warehouse wallfrequently bump, the scene often when installs the strobe can not butknock the warehouse wall a part, causes the warehouse wall theintensity to weaken, based on, we uses the manual plate strobe,matches the guidance wheel under the damper plate, simultaneously hasthe positioning device on the axis. economic efficiency analysis In needs 2000t/under the h transport capacity condition,arranges two University of Taiwan stoker with simultaneously toarrange four K 14 stokers or four Electric vibrator stokers its economicefficiency quite is as follows. 1) Weighed proclaims the mining quantity The big Weighed room not only causes the mining quantity toincrease, moreover can bring many negative effects along with it, fourreciprocation types stoker union arrangement, should consider betweenthe equipment must remain has the overhaul space, holds Zuo the space,like this, its Weighed room resilience is bigger than two University ofTaiwan reciprocation type stoker; But if uses four vibrations todeceive the material machine, needs the height difference in a bigway, moreover because its noise is big, the small Weighed room cannotsatisfy its request. Speaking of this parameter, arranges twoUniversity of Taiwan stoker the plan is most economical. 2) power consumption comparison The large-scale reciprocation type stoker power is notcertainly big, two University of Taiwan stoker power consumption andfour K 14 stokers or Electric vibrator the stoker is nearly impartial. 3) equipment operating cost comparison Large-scale stoker vulnerable very few, moreover because usesthe standard hard tooth face reduction gear, causes the servicequantity minimum, but four stokers because number increasing, themaintenance cost also is corresponding is large-scale stoker twotimes, Electric vibrator the stoker is unable in this point with it to compare. Develops the large-scale reciprocation type stoker, met our countrycoal need to develop, expanded in the coal mine production systemdesign to give the coal equipment the shaping scope. In particular inJining two mine pits success uses, for me The country provided has been new large-scale for the coalequipment, should give the vigorously promoted use. 中文译文往复给煤机现状一、往复式给煤机其自身结构的优越性1) 结构简单，维修量小在往复式给煤机中，电动机和减速器均采用标准件，其余大部分是焊接件，易损部件少，用在煤矿恶劣条件下，其适用性深受使用单位的好评。2 )性能稳定往复式给煤机对煤的牌号，粒度组成，水分、物理性质等要求不严，当来料不均匀，水分不稳定且夹有大块煤、橡胶带、木头及钢丝等时，仍能正常工作。3 )噪音低往复式给煤机是非振动式给料设备其噪音发生源只有电动机和减速器，而这两个的噪音都很低。尤其在井下或煤仓等封闭型场所，噪音无法扩散，这一点是电动给料机所无法达到的。4 )安装方便、高度小往复式给煤机一般安装在煤仓仓口，不需另外配制仓口闸门馏槽及电动机支座，安装可一步到位，调整工作量小，而电动给煤机由于不能直接承受仓压，需要另外安放仓口过渡溜槽，相比之下，往复式给煤机占有高度小，节省了建筑面积和投资。二、研制大型往复式给煤机的必要性正是由于往复式给煤机具有上述的特点，我们认为，在煤矿井下和地面生产系统的咽喉环节，及在其他需要控制噪音的环节，应首选往复式给煤机。扩大系列的往复式给煤机应满足下列要求。1 )满足大型矿井生产能力的要求随着我国煤矿井型的不断扩大，小时生产能力也在增加，例如：井型为240万ta，300万ta。4(万ta的矿井，小时生产能力分别为了42“h，928th，1238th。矿井小时生产能力的增加，要求提高给煤机的生产能力。目前，矿井井下原煤运输越来越多地采用胶带输送机，也就是说，井下使用给煤机的环节增加了。虽然可以采用多台小型号给煤机联合布置来满足大生产能力的要求，但布置多台给煤机需要扩大硐室，增加工程投资 况且多台布置，系统可靠性降低，噪音增大，出问题的机率也相对增多给维修带来一定的麻烦。在使用胶带输送机的装车系统，是地面生产系统中使用给煤机最多的地方，而且要求给煤能力比较大。装车系统若采用电振给料机，不但增加了装车的高度而且噪音很大。安装大型往复式给煤机，不仅使小时生产能力增大，而且也为装车系统设备的选型提供了更大的可选范围。2) 与主井井底装载带式(板式)输送机配套主井井底装载带式(板式)定量输送机式井底装载设备的发展趋势，被列为煤炭重点科研项目，定量输送机慢速装载时要求给煤设备的能力801)ttb以上，现有的K系列给煤机达不到这一要求。虽然也可采用给料闸门料，但给料闸门的给料量易受原煤的水份、粒度影响，使给料不均匀。而大型往复式给煤机可满足这一要求三、 大型往复式绐煤机的结构形式特点我们通过对以往给煤机的调查进行分析，对结构型式进行了周密的计算，对关键受力部位如槽箱、双连杆、底部托辊等进行了受力分析，利用有限元原理进行校核计算。共有以下五个特点。1)整机采用框袈可卸式由于考虑到井下运输的方便和井下工矿的限制，整机采用分体式，而且考虑到井下焊接的不便，尽 用螺栓副联接，侧板考虑到外鼓的可能与内壁磨损的需要，在外侧加筋内侧铺设衬板，加强了整体的刚度和强度。2) 增加导板的导向与支撑装置在做往复运动的导板下增设几组托辊轮，一方面变导板的滑动摩擦为滚动磨擦，减少了磨损，另一方面也使导板的刚度提高。另外，为防止导板在运动过程中有跑偏现象，在导板两侧安装导向轮。3) 对导板结构进行优化以往K系列给煤机的平板闸门，物料在运送中存在不少问题，给料量一直不能提高的关键也在于此。为此，我们对导板进行了优化，设计为阶梯型，不但使物料处理量加大了，而且导板本身的强度也得到进一步地提高。4) 变扇型闸门为手动平板闸门控制来料多少的关键取决于闸门，闸门在以往的K系列中一直采用扇型结构，但从现场使用中发现，扇型闸门与仓壁经常相碰，现场往往在安装闸门时不得不把仓壁敲去一部分，使仓壁的强度削弱，基于次，我们采用手动平板闸门，在闸板下配导向轮，同时在轴上配有定位装置。四、经济效益分析在需要2000th运输能力的条件下，布置两台大型给煤机与同时布置四台K一4给煤机或四台电振给煤机其经济效益比较如下。1) 硐宣开采量大硐室不仅使开采量增大，而且会随之带来许多负效应，四台往复式给煤机联合布置，应考虑设备之间要留有检修空间，操阼空间，这样，其硐室工程量大于两台大型往复式给煤机；而若采用四台振动绐料机，需要高度差大，而且由于其噪音大，小的硐室也不能满足其要求。就这一参数而言，布置两台大型给煤机的方案是最经济的。2) 耗电量比较大型往复式给煤机的功率并不大，两台大型给煤机的耗电量与四台K一4给煤机或电振给煤机几乎持平。3) 设备运行费用比较大型给煤机的易损件很少，而且由于采用标准硬齿面减速器，使维修量极小，而四台给煤机由于台数的增多，维修费也相应是大型给煤机的两倍，电振给煤机在这一点上更无法与之相比。研制大型往复式给煤机，适应了我国煤炭发展的需要，扩大了煤矿生产系统设计中给煤设备的选型范围。尤其是在济宁二号矿井的成功使用，为我国提供了新的大型给煤设备，应予大力推广使用。中 国 矿 业 大 学本科生毕业论文姓 名：高 慧 学 号： 14030389 学 院： 应用技术学院 专 业： 机械工程及自动化 论文题目： 防窜仓往复式给煤机 专 题： 指导教师： 黄嘉兴 职 称：副教授 2007年 6 月 徐州中国矿业大学毕业设计任务书学院 应用技术学院 专业 年级 机自03-2班 学生姓名 高慧 任务下达日期：2007年 1 月 11 日毕业设计日期：2007 年 3月 25日 至 2007年6月20日毕业设计题目：往复式防窜仓给料机毕业设计专题题目： 毕业设计主要内容和要求： 了解往复式给料机的用途，工作原理，以及工作存在的问题，设计出一台往复式防窜仓给料机。参数：给料量1200吨/小时，往复行程250-300mm，给料电机功率18-22KW，防窜仓机构电机功率4-4.5KW。1、 设计完成总体装配图设计。2、 防窜仓机构设计，液压系统设计。3、 泵站设计，液压元件选型。4、 完成主要传动组件，零件的工件图设计。（曲柄滑块机构）5、 编写完成整体设计计算说明书。院长签字： 指导教师签字：摘 要往复式给煤机安装在煤仓下口处，在煤矿井下生产中，设置一定容量的煤仓对于保证消峰平谷和高产、高效是十分必要的。往复式给煤机由机架、底板（给煤槽）、传动平台、漏斗、闸门、托辊等组成。当电机开动后经弹性联轴器、减速机、曲柄连杆机构拖动倾料13的底板在辊上作直线往复运动，煤均匀地卸到其他设备上。它可以有效地提高工作面采掘设备的利用率，充分发挥运输系统的潜力，保证连续均衡生产。但是，煤仓窜仓事故在我国煤矿经常发生。窜仓事故常造成设备严重损坏，井下停产，当窜仓煤量较大时，还会阻塞巷道，造成运输巷通风不畅，引起瓦斯爆炸等事故。为了防止和降低煤矿井下煤仓窜仓造成的设备损坏、人员伤亡、阻塞巷道和影响生产等危害，设计了一种用于往复式给煤机的防窜仓装置，从而为煤仓窜仓的防治提供了一个新的途径。关键词：曲柄滑块机构 ；煤仓窜仓 ；防窜仓装置 ；往复式给料机ABSTRACTThe reciprocation type stoker installs in bunker the end openingplace, in the coal mine mine shaft production, the establishmentcertain capacity bunker disappears peak Pinggu regarding the guaranteeand the high production, is highly effective is extremely essential.
