【正文】 leads to adopt the coal machine research contentsThe local electricity leads to adopt coal machine a representative model and foreign electricity to lead to adopt coal machine to pare and have already near in the total parameter function foreign 20 centuries age initial stage of 9 o some key partses and it the total function, function, orientation scope...etc. still treat further perfect with online work condition monitor, breakdown diagnosis and forecast, the signal deliver and adopt coal machine to automatically control, spread a feeling machine etc. the intelligence turn technique and abroad to pare to still have a bigger margin.As a result the local electricity leads intelligence of adopt the coal machine to turn degree low, the equipments credibility, safety with can support sex worse, the local electricity will lead to adopt coal machine from now onMain research contents is as follows:(1)Further perfect municate with exaltation change the Pin adjust soon credibility of lead the point is perfect and raises system device of anti earthquake, spread hot and defend tide etc. function。s machine。s probing into a technique to be think be a kind of coal rock boundary which have application foreground mostIdentify a method。s machine munication interface, break down diagnosis sketch to show and store, wireless control from a distance, lead functions such as control and protection etc.. Japan1987The year continuously develops to succeed various series alternate current of the MCLEDR which mow electrical engineering to lengthways set outs to lead to adopt coal machine behind and developped to cut many electrical engineering alternate currents of mow the electrical engineering horizontal decorations to lead to adopt coal machine again for the last few the coal machine has tiny machine work condition a monitor and breaks down diagnosis system, can the numerical manifestation lead speed, roller position, stay a bottom coal thickness, electrical engineering load and everywhere temperature, have wireless remote control, and can add infrared ray shoot the machine manipulate a liquid to press a support. Poland the KOMAG mine for minerals a mechanization research centerPoland continuously developped KSE in developping successful KSE a 344 thin coal seam alternate currents with Chinese cooperation to lead foundation of adopt the coal machine a 360, KSE a 700, KSE one 800 RWs/2 BPs, KSE a 535 Ss/2 BPs, KSE1000 type etc. alternate current lead to adopt coal the coal machine cuts deeply from 630171111 raise 8001000 mms. RussiaThe former Soviet Union 7039。s in 20 centuries develops a direct current to lead to adopt coal machine one after , each mainly adopted coal machine a research a manufacturing a pany to all lead to adopt coal machine to carry on to the electricity in the world a great deal of of study a age expected to appear alternate current to lead to adopt coal machine , the big power electricity which develops to gather electronics, microelectronics, information management and calculator intelligence technique in the integral whole leads to adopt coal machine, like the LS series of American JOY pany, British LongAirdox the Electra, SL series of the pany, the EDW, SL series of German Eickhof pany, three wells in Japan three pond creation the MCLEDR of series etc. the electricity lead to adopt coal electricity leads to adopt coal machine good and dependable sex with its function parameter Gao, automation degree Gao, operation convenience, supervision protection and examination the function perfect and economic performance Gao Deng339。t easily be continuously pounded at influence。Cut to mow a parameter。s method to press the type of lead the electrical engineering and can is divided into direct current to lead and municates to electricity in earlier period leads to adopt coal machine to mostly adopt direct current to adjust soon success from the mid 8039。(4)Development can the mineral of four quadrant movements use to municate change the Pin adjust to soon to adopt coal function to adapt the demand that bigger Qing Cape coal seam mine。1 國外電牽采煤機發(fā)展概況自1976年研制成功直流電牽引采煤機后，基本停止了液壓牽引采煤機的開發(fā)研究，陸續(xù)開發(fā)了多種形式電牽引采煤機。71．55采煤機總功率1 940kW， 牽引速度30m／min。2 國內(nèi)電牽引采煤機發(fā)展概況近年來。(2)牽引功率均在80 kW 以上，最大已達(dá)220 kW。國外采煤機元部件設(shè)計壽命：齒輪12500h，軸承20 000—30000h，電機絕緣壽命44000h，滾筒采煤64萬t。監(jiān)控保護(hù)系統(tǒng)智能化主要功能：(1)負(fù)載控制通過截割電機電流的監(jiān)測，調(diào)整采煤機的牽引速度，使采煤機在不同工況下以最優(yōu)化的參數(shù)進(jìn)行工作，保證傳動系統(tǒng)不易受持續(xù)沖擊影響；(2)工作面定位控制 識別采煤機在工作面的位置，在機頭、機尾自動減速和停止，與支架配合實現(xiàn)自動隨機移架；(3)與工作面輸送機聯(lián)機負(fù)荷控制 通過輸送機的負(fù)荷監(jiān)測來調(diào)節(jié)采煤機的采煤量，使采煤機和輸送機的生產(chǎn)能力相匹配；(4)自動調(diào)高控制 將具有一定分辨率的煤巖分界識別傳感器結(jié)合計算機控制，組成煤巖分界傳感裝置及煤巖分界識別系統(tǒng)。(7)專家系統(tǒng)和故障診斷把來自監(jiān)控、性能檢測和運行參數(shù)的數(shù)據(jù)和信息與以往機器維護(hù)、使用情況進(jìn)行比較，對機器的健康運行進(jìn)行診斷，也可對特定錯誤和推薦方案提供風(fēng)險評估。這種～ 拖一的牽引系統(tǒng)也正被逐步采用，成為電牽引技術(shù)發(fā)展的又一特點。1)爬底板方式如MG344一PWD型、EDW300一LN型、MCLE—DR7575M型等采煤機。機身懸在機道里，前滾筒反轉(zhuǎn)割底，后滾筒正轉(zhuǎn)割頂。除了傳統(tǒng)的縱向布置外，還有橫向多電機并聯(lián)布置，如1K103型、MG344型等?？刂浦噶睢⒈Ｗo(hù)、顯示等信息也由同一根電纜傳送，這種電牽引裝置的電牽引低速性能差，控制信號易受外界干擾，信息傳送復(fù)雜，拖拽電纜產(chǎn)生故障易引起電氣調(diào)速裝置損壞，發(fā)電運行時拖拽電纜斷路會引起跑車。(2)加大功率和功率密度。中壓機載是1—2m薄煤層交流變頻電牽引采煤機的關(guān)鍵技術(shù)，必須盡快突破。4 國內(nèi)電牽引采煤機研究內(nèi)容國內(nèi)電牽引采煤機代表機型與國外電牽引采煤機相比，在總體參數(shù)性能方面已接近國外2
