5、ries of German Eickhof company, three wells in Japan three pond creation the MCLE-DR of series etc. the electricity lead to adopt coal machine.The electricity leads to adopt coal machine good and dependable sex with its function parameter Gao, automation degree Gao, operation convenience, supervisio
6、n protection and examination the function perfect and economic performance Gao Deng3s advantage be quickly expanded an usage. 1 The foreign electricity leads long to adopt the coal machine development general situation 1.1German Eickhof company After 1976 developped successful direct current to lead
7、 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 machine.90The SL series that the age develop is horizontal to arrange the alternate current lead to
8、adopt coal machine, cut to mow electrical engineering to arrange in shaking arm.Among them, the S type electricity leads to adopt coal machine to pack machine power to reach to one 580 kWs, biggest lead dint 998 LSOkNs.SL300 type electricity leads to adopt coal machine to always pack machine power o
9、ne 018 kWs, the adoption double change once the Pin machine drag along one system, biggest lead speed to reach to 54.5 ms/rai system the system have to hand over with each other a type a person the machine dialogue, equipments healthily forecasts, the on-line control, data deliver etc. function. 1.2
10、 :British Long-Airdox company After 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,
11、and then develop into an Electra1000 type direct current to lead to adopt coal machine.90Age, 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, EL1
12、000, EL1500, EL3000 type.At 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
13、 break down diagnosis, data to deliver etc. function. 1.3American JOY company 2070s in centurys 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 ISs-7s again etc. type man
14、y electrical engineerings are horizontal to arrange the direct current lead to adopt coal machine.71.55 adopt the coal machine total power one 940 kWs, lead the speed 30 ms/min.Adopt a strong dint sells a track to have no chain to lead system, the enlargement chain track stanza is apart from with wi
15、dth, 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 persons machine communication interface, break down diagnosis sketch to show and store, wireless control from a distance, lead functions such as control and protect
16、ion etc. 1.4 Japan 1987The year continuously develops to succeed various series alternate current of the MCLE-DR 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 eng
17、ineering horizontal decorations to lead to adopt coal machine again for the last few years.Adopt 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 engineer
18、ing load and everywhere temperature, have wireless remote control, and can add infrared ray shoot the machine manipulate a liquid to press a support. 1.5 Poland the KOMAG mine for minerals a mechanization research center Poland continuously developped KSE in developping successful KSE a 344 thin coa
19、l 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 machine.Adopt the coal machine cuts deeply from 630171111 raise 800-1000 mms. 1.6 Russia
20、 The former Soviet Union 70s in 20 centuries develops a K128 Is-Is.The direct current after lead adopt coal machine develops to succeed various direct currents to lead to adopt coal machine one after another again.9The age of the o developped K a 8 etc. alternate currents to lead to adopt coal machi
21、ne.Every consider, the electricity of Russia leads to adopt coal machine power smaller, the direct current lead and the function parameter is lower. 2 The local electricity leads to adopt the coal machine development general situation In recent years.The our country electricity led to adopt develop
22、of coal machine to obtain a substantial progress with development, carry on two developments in digesting to absorb abroad to usher in to adopt the coal machine technical foundation and owned many have an independent intelligent property right of change a product, at our country coal mine comprehensive the mechanization adopt coal work noodles, coal science studies total Shanghai branch in the hospital and Poland cooperates, after the local initiative develop successful our countrys first adoption exchanges change Pin adjust soon technical thin coal seam to climb scaleboard to adopt coal
