【正文】 英文原文The Technical Situation and Development Trend of Electrical Haulage ShearersAbstract： In this paper，the technical development history and technical situation of electrical haulage shearersfor thin seam of China are reviewed，and the main technical parameters，general structure，serialization anddevelopment trend of such sheares are introduced．Keywords： thin seam；shearer；electrical haulage；multi—motor driving；transverse arrangementGerman Eickhoff pany and American JOY pany, the mid 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。s advantage be quickly expanded an usage.1 The foreign electricity leads long to adopt the coal machine development general situation Eickhof panyAfter 1976 developped successful direct current to lead to adopt coal machine, it was basic to stopped a liquid to press to lead a development research of adopt the coal machine and continuously developped various form electricities to lead to adopt coal SL series that the age develop is horizontal to arrange the alternate current lead to adopt coal machine, cut to mow electrical engineering to arrange in shaking them, the S type electricity leads to adopt coal machine to pack machine power to reach to one 580 kWs, biggest lead dint 998 type electricity leads to adopt coal machine to always pack machine power one 018 kWs, the adoption double change once the Pin machine drag along one system, biggest lead speed to reach to ms/rai system the system have to hand over with each other a type a person the machine dialogue, equipments healthily forecasts, the online control, data deliver etc. function. :British LongAirdox panyAfter 1984 developped success the first set cut to mow electrical engineering to arrange at many decorations with horizontal electrical engineerings of shake the arms get Electra550 type direct current led to adopt coal machine, at its foundation top enlargement power, and then develop into an Electra1000 type direct current to lead to adopt coal , on the model foundation of the Electra series, enlargement power, the improvement controls system, developped EL series alternate current to lead to adopt coal machine and the main model contains EL600, EL1000, EL1500, EL3000 EL series model up equip of the Impact integrate protection and supervise and control system and have burden to control, machine supervision, adopt coal machine to automatically position, automatically key up, district control, the intelligence turn safe catena and random break down diagnosis, data to deliver etc. function. JOY pany207039。s in century39。s developping successfully a 1 ls many electrical engineerings is successfullyhorizontal to arrange the direct current after lead adopt coal machine continuously developped a 2 IS ISs7s again etc. type many electrical engineerings are horizontal to arrange the direct current lead to adopt coal adopt the coal machine total power one 940 kWs, lead the speed 30 ms/ a strong dint sells a track to have no chain to lead system, the enlargement chain track stanza is apart from with width, and adopt a forging to sell a row。Equip and 6 LS5 type the in general use JNA machine carry calculator information center and have person39。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 liq
