JOY pany207039。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 in century39。Equip and 6 LS5 type the in general use JNA machine carry calculator information center and have person39。s in 20 centuries develops a K128 direct current after lead adopt coal machine develops to succeed various direct currents to lead to adopt coal machine one after another age of the o developped K a 8 etc. alternate currents to lead to adopt coal 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 situationIn recent our country electricity led to adopt develop 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 prehensive 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 country39。t easily be continuously pounded at influence。s identifying to adopt coal machine is work the position of noodles, automatically decelerate in the machine head, machine tail with stop, match with a realization auto with support to random move。(4)Automatically keying up a control will have the coal rock boundary of certain resolution to identify to spread a feeling machine to bine a calculator control and constitute a coal rock boundary to spread feeling device and coal rock boundary to identify already apply to physically or just be placed in research at the production currently with experiment the coal rock of stage identify a method and analytical the system mainly have:Remember the intelligence distance control, the analytical and natural D of the vibration frequency chart shoot line, measure dint to cut Chi, radioisotope, Zao voice the infrared ray, radar probe into etc..Remember an intelligence distance to control a coal rock boundary to identify and control system among them an application at most is what foreign main model adopt to automatically key up a technique currently in actually the radar39。(5)Circulate appearance supervision and manifestation adopts coal machine a data to collect systemCan collect machine parameter:If the Eickhof pany SL series adopts coal machine a material to have MICOS68 mineralses to use tiny machine system, main course 10 single submenus include to adopt coal luck to go appearance。Cut to mow a parameter。Water measure, water pressure。Diagnosis, early warning(password) etc., the most protection item can hand over a way to with each other shield through person39。(6)The data deliver, agreeable slot control and ground supervision39。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。s having no chain to lead have already eliminate, wheel gear one chain track type39。s sell is replace by the Chi track and weld structure to change whole nicety cast or forge, the width enlarge, the stanza is apart from to
