1. Ibali lekhonkco lekhonkco elijikelezayo lokumbiwa kwemigodi
Ngokunyuka kwemfuno yamandla amalahle kuqoqosho lwehlabathi, oomatshini bokwemba amalahle baphuhliswe ngokukhawuleza. Njengezona zixhobo ziphambili zokumbiwa kwamalahle okubanzi kumgodi wamalahle, icandelo lothumelo kwi-scraper conveyor nalo liphuhliswe ngokukhawuleza. Ngandlela ithile, uphuhliso lwe-scraper conveyor luxhomekeke kuphuhliso lweimigodi high-amandla umjikelo link chain. I-mining high-high-high-round round link chain yinxalenye ephambili ye-chain scraper conveyor kumgodi wamalahle. Umgangatho wayo kunye nokusebenza kwayo kuya kuba njalokuchaphazela ngokuthe ngqo ukusebenza kakuhle kwezixhobo kunye nokukhutshwa kwamalahle kumgodi wamalahle.
Uphuhliso lwemigodi yamandla aphezulu kumjikelo wekhonkco lomjikelo ikakhulu lubandakanya le miba ilandelayo: uphuhliso lwentsimbi yokumbiwa kwekhonkco lekhonkco elijikelezileyo, uphuhliso lwetekhnoloji yonyango lobushushu betsheyini, ukulungiswa kobungakanani bentsimbi engqukuva kunye nokumila kwekhonkco, uyilo olwahlukileyo lwekhonkco kunye uphuhliso lweteknoloji yokwenza ikhonkco. Ngenxa yolu phuhliso, iimpawu zomatshini kunye nokuthembeka kweimigodi ikhonkco ikhonkco ikhonkcoziphuculwe kakhulu. Ukucaciswa kunye neepropathi zoomatshini zekhonkco eliveliswe ngamashishini athile aphambili okwenziwa kwetsheyini ehlabathini agqithise kakhulu umgangatho waseJamani we-DIN 22252 osetyenziswa kakhulu kwihlabathi.
Intsimbi yokuqala yodidi oluphantsi lwemigodi ejikelezileyo yekhonkco phesheya ubukhulu becala yayiyintsimbi yekhabhoni yemanganese, enomxholo ophantsi wekhabhoni, umxholo wento yealloyi ephantsi, ukuqina okuphantsi, kunye nedayamitha yetsheyini < ø 19mm. Ngeminyaka yoo-1970, i-manganese nickel chromium molybdenum uthotho lweentsimbi zodidi oluphezulu zaphuhliswa. Iintsimbi eziqhelekileyo ziquka i-23MnNiMoCr52, i-23MnNiMoCr64, njl. Ezi zintsimbi zinobunzima obuhle, ukuqina kunye namandla kunye nokuqina, kwaye zifanelekile ukuveliswa kwekhonkco elikhulu le-C-grade. Intsimbi ye-23MnNiMoCr54 yaphuhliswa ekupheleni kweminyaka yoo-1980. Ngokusekelwe kwintsimbi ye-23MnNiMoCr64, umxholo we-silicon kunye ne-manganese wancitshiswa kwaye umxholo we-chromium kunye ne-molybdenum yanda. Ukuqina kwayo kwakungcono kunoko kwentsimbi ye-23MnNiMoCr64. Kwiminyaka yakutshanje, ngenxa yophuculo oluqhubekayo lweemfuno zokusebenza zetsheyini yentsimbi ejikelezayo kunye nokwanda okuqhubekayo kwenkcazo yetsheyini ngenxa yokwembiwa kwamalahle ngoomatshini kwimigodi yamalahle, ezinye iinkampani zamatsheyini ziye zaphuhlisa amanqanaba amatsha entsimbi akhethekileyo, kunye nezinye iipropathi zezi. amabakala amatsha entsimbi angaphezulu kwe-23MnNiMoCr54 yentsimbi. Ngokomzekelo, i-"HO" yensimbi eyenziwe yinkampani yaseJamani ye-JDT inokunyusa amandla ekhonkco nge-15% xa kuthelekiswa ne-23MnNiMoCr54 yensimbi.
2.Iimeko zenkonzo ye-Mining chain kunye nohlalutyo lokungaphumeleli
2.1 iimeko zenkonzo yekhonkco lemigodi
Iimeko zenkonzo yekhonkco elijikelezayo zezi: (1) amandla oxinzelelo; (2) Ukudinwa okubangelwa ngumthwalo we-pulsating; (3) Ukruthakruthwano kunye nokuguga kwenzeka phakathi kwamakhonkco ekhonkco, amakhonkco ekhonkco kunye ne-chain sprockets, kunye namakhonkco amakhonkco kunye namacwecwe aphakathi kunye namacala e-groove; (4) Umhlwa ubangelwa sisenzo samalahle acoliweyo, umgubo wamatye kunye nomoya ofumileyo.
2.2 ikhonkco lemigodi lidibanisa uhlalutyo lokungaphumeleli
Iindlela zokuqhawula amakhonkco ekhonkco lokumbiwa kwemigodi zinokwahlulwa ngokufanelekileyo zibe: (1) umthwalo wekhonkco udlula umthwalo wawo wokuqhawula omileyo, okukhokelela ekuqhekekeni kwangaphambi kwexesha. Oku kwaphuka ubukhulu becala kwenzeka kwiindawo ezineziphene zekhonkco igxalaba ikhonkco okanye indawo ethe tye, njengokuqhekeka ukusuka kwi-flash butt welding ubushushu kwindawo echaphazelekayo kunye nokuqhekeka kwezinto zebha; (2) Emva kokusebenza ixesha elithile, ikhonkco yekhonkco yemigodi ayizange ifike kumthwalo wokuphuka, okubangelwa ukuphuka okubangelwa ukukhathala. Oku kwaphuka kwenzeka kakhulu ekudibaneni kwengalo ethe tye kunye nesithsaba sekhonkco lekhonkco.
Iimfuno zokumbiwa kwekhonkco elijikelezayo: (1) ukuba nomthwalo ophezulu wokuthwala umthwalo phantsi kwezinto ezifanayo kunye necandelo; (2) ukuba nomthwalo ophezulu wokuqhawula kunye nobude obungcono; (3) ukuba ne-deformation encinci phantsi kwesenzo somthamo omkhulu wokulayisha ukuqinisekisa i-meshing elungileyo; (4) ukuba namandla aphezulu okudinwa; (5) ukuba nokumelana nokunxiba okuphezulu; (6) ukuba nokuqina okuphezulu kunye nokufunxa ngcono komthwalo wempembelelo; (7) imilinganiselo yejometri ukuhlangabezana nomzobo.
I-3.Inkqubo yokuvelisa i-Mining chain
Inkqubo yemveliso yekhonkco lemigodi: ukusika ibha → ukugoba nokunitha → ikhonkco → ukuwelda → uvavanyo lokuqala lobungqina → unyango lobushushu → uvavanyo lobungqina besibini → ukuhlola. I-Welding kunye nonyango lobushushu ziinkqubo eziphambili kwimveliso ye-mining round link chain, echaphazela ngokuthe ngqo umgangatho wemveliso. Imilinganiselo ye-welding yenzululwazi inokuphucula isivuno kunye nokunciphisa iindleko zemveliso; inkqubo efanelekileyo yonyango lokushisa inokunika ukudlala ngokupheleleyo kwiipropati eziphathekayo kunye nokuphucula umgangatho wemveliso.
Ukuze kuqinisekiswe umgangatho we-welding we-mining chain, i-arc welding manual kunye ne-resistance butt welding iye yapheliswa. I-flash butt welding isetyenziswa ngokubanzi ngenxa yeenzuzo zayo ezibalaseleyo ezifana neqondo eliphezulu lokuzisebenzela, ukuqina okuphantsi kwabasebenzi kunye nomgangatho wemveliso ozinzile.
Okwangoku, unyango lobushushu lwekhonkco elijikelezayo lemigodi ngokubanzi lithatha ukufudumeza okuphakathi kwamaza omoya, ukucima okuqhubekayo kunye nokufudumeza. Undoqo wokufudumeza okuphakathi kwe-frequency induction kukuba ukwakheka kwemolekyuli yento ishukunyiswa phantsi kommandla we-electromagnetic, iiathom zifumana amandla kwaye zingqubane ukuvelisa ubushushu. Ngexesha lonyango lobushushu obuphakathi, i-inductor idityaniswe ne-AC ye-frequency frequency ethile, kwaye amakhonkco amakhonkco ahamba ngesantya esifanayo kwi-inductor. Ngale ndlela, i-current induced current kunye ne-frequency efanayo kunye necala elichaseneyo njengoko i-inductor iya kuveliswa kwiikhonkco zekhonkco, ukwenzela ukuba amandla ombane aguqulwe abe ngamandla obushushu, kwaye amakhonkco amakhonkco angafudunyezwa kwiqondo lokushisa elifunekayo ukucima. kunye nokuphumla ngexesha elifutshane.
Ukufudumeza okuphakathi kwe-frequency induction inesantya esikhawulezayo kunye ne-oxidation encinci. Emva kokucima, ukucima isakhiwo esihle kakhulu kunye nobukhulu bengqolowa ye-austenite inokufumaneka, okuphucula amandla kunye nokuqina kwekhonkco lekhonkco. Kwangaxeshanye, nayo ineengenelo zokucoceka, ucoceko, uhlengahlengiso olulula kunye nokusebenza kakuhle kwemveliso. Kwinqanaba lokufudumala, indawo ye-welding ye-chain link idlula kwiqondo lokushisa eliphezulu kwaye isusa inani elikhulu lokucima uxinzelelo lwangaphakathi ngexesha elifutshane, elinempembelelo ebaluleke kakhulu ekuphuculeni iplastiki kunye nokuqina kwendawo ye-welding kunye nokulibazisa ukuqaliswa. kunye nophuhliso lweentanda. Ubushushu bobushushu obuphezulu kwigxalaba lekhonkco lekhonkco buphantsi, kwaye linobulukhuni obuphezulu emva kobushushu, obunceda ukunxitywa kwekhonkco lekhonkco ngexesha lenkqubo yokusebenza, oko kukuthi, ukunxiba phakathi kwamakhonkco ekhonkco kunye ne-meshing phakathi kwekhonkco. amakhonkco kunye ne-chain sprocket.
