1. Ibali leekhonkco ezijikelezileyo zokwemba
Ngenxa yokwanda kwemfuno yamandla amalahle kuqoqosho lwehlabathi, oomatshini bokwemba amalahle baphuhliswe ngokukhawuleza. Njengesixhobo esiphambili sokumbiwa kwamalahle oomatshini abapheleleyo kwimigodi yamalahle, icandelo lokudlulisa kwi-scraper conveyor nalo liphuhliswe ngokukhawuleza. Ngandlela thile, uphuhliso lwe-scraper conveyor luxhomekeke kuphuhliso lweumgodi wekhonkco elijikelezileyo onamandla aphezuluUkumbiwa kwetsheyini yekhonkco ejikelezileyo enamandla aphezulu yeyona nto iphambili kwi-chain scraper conveyor kwimigodi yamalahle. Umgangatho wayo kunye nokusebenza kwayo kuya kuba luncedo.ichaphazela ngokuthe ngqo ukusebenza kakuhle kwezixhobo kunye nokuveliswa kwamalahle kwimigodi yamalahle.
Uphuhliso lwe-“round link chain” olunamandla aphezulu luquka ikakhulu ezi zinto zilandelayo: uphuhliso lwentsimbi yokumba i-“round link chain”, uphuhliso lwetekhnoloji yonyango lobushushu lwe-“chain”, ukulungiswa kobungakanani kunye nemilo ye-“round link chain”, uyilo lwe-“chain” olwahlukileyo kunye nophuhliso lwetekhnoloji yokwenza i-“chain”. Ngenxa yolu phuhliso, iimpawu zoomatshini kunye nokuthembeka kwe-“mechain”utyathanga lwekhonkco elijikelezileyo lokumbaziphuculwe kakhulu. Iinkcukacha kunye neempawu zoomatshini zetsheyini eziveliswa ngamanye amashishini avelisa itsheyini aphambili ehlabathini zidlule kakhulu umgangatho waseJamani i-DIN 22252 osetyenziswa kakhulu ehlabathini.
Intsimbi yokuqala ekumgangatho ophantsi yokumba i-round link chain phesheya yayiyeyona ntsimbi ye-carbon manganese, enomxholo ophantsi wekhabhoni, umxholo ophantsi we-alloy element, ukuqina okuphantsi, kunye nobubanzi beketanga < ø 19mm. Kwiminyaka yoo-1970, kwaveliswa iintsimbi zeketanga ze-manganese nickel chromium molybdenum series. Iintsimbi eziqhelekileyo ziquka i-23MnNiMoCr52, i-23MnNiMoCr64, njl. ezi ntsimbi zinokuqina okuhle, ukuwelda kunye namandla kunye nokuqina, kwaye zifanelekile ukuvelisa iketanga le-C-grade elikhulu. Intsimbi ye-23MnNiMoCr54 yaphuhliswa ngasekupheleni kweminyaka yoo-1980. Ngokusekelwe kwintsimbi ye-23MnNiMoCr64, umxholo we-silicon kunye ne-manganese wancitshiswa kwaye umxholo we-chromium kunye ne-molybdenum wanda. Ukuqina kwayo kwakungcono kunokwentsimbi ye-23MnNiMoCr64. Kwiminyaka yakutshanje, ngenxa yokuphucuka okuqhubekayo kweemfuno zokusebenza kwetyathanga lentsimbi elijikelezileyo kunye nokwanda okuqhubekayo kweenkcukacha zetyathanga ngenxa yokumbiwa kwamalahle oomatshini kwimigodi yamalahle, ezinye iinkampani zetyathanga ziye zaphuhlisa ezinye iiklasi zentsimbi ezintsha ezikhethekileyo, kwaye ezinye iipropati zezi klasi zentsimbi zintsha ziphezulu kunentsimbi ye-23MnNiMoCr54. Umzekelo, intsimbi "HO" eyenziwe yinkampani yaseJamani iJDT inokunyusa amandla etyathanga nge-15% xa kuthelekiswa nentsimbi ye-23MnNiMoCr54.
2. Iimeko zenkonzo yetsheyini yokwemba kunye nohlalutyo lokusilela
2.1 Iimeko zenkonzo yecandelo lemigodi
Iimeko zenkonzo yekhonkco elijikelezileyo zezi: (1) amandla oxinzelelo; (2) Ukudinwa okubangelwa ngumthwalo otyhafayo; (3) Ukungqubana kunye nokuguguleka kwenzeka phakathi kweekhonkco zekhonkco, iikhonkco zekhonkco kunye nee-sprocket zekhonkco, kunye neekhonkco zekhonkco kunye neepleyiti eziphakathi kunye namacala e-groove; (4) Ukugqwala kubangelwa yintshukumo yamalahle acoliweyo, umgubo wamatye kunye nomoya ofumileyo.
2.2 Uhlalutyo lokusilela kwamakhonkco okudibanisa umgodi
Iintlobo zokuqhekeka kweekhonkco zemigodi zinokwahlulwahlulwa zibe: (1) umthwalo wekhonkco udlula umthwalo wawo wokuqhekeka ongashukumiyo, nto leyo ebangela ukwaphuka kwangaphambi kwexesha. Olu kwaphuka ludla ngokwenzeka kwiindawo ezineziphene zegxa lekhonkco lekhonkco okanye indawo ethe tye, njengokuqhekeka okuvela kwindawo echaphazelekileyo kubushushu kunye nokuqhekeka kwezinto zebha nganye nganye; (2) Emva kokubaleka ixesha elithile, ikhonkco lekhonkco lemigodi alifikanga kumthwalo wokuqhekeka, nto leyo ebangela ukwaphuka okubangelwa kukudinwa. Olu kwaphuka ludla ngokwenzeka xa kuqhagamshelwe ingalo ethe tye kunye nesithsaba sekhonkco lekhonkco.
Iimfuneko zokumbiwa kwekhonkco lekhonkco elijikelezileyo: (1) ukuba nomthamo ophezulu wokuthwala umthwalo phantsi kwezinto ezifanayo kunye necandelo; (2) ukuba nomthwalo ophezulu wokuqhekeka kunye nokwandiswa okungcono; (3) ukuba nokuguquguquka okuncinci phantsi kwesenzo somthamo ophezulu wokulayisha ukuqinisekisa ukuba i-meshing ilungile; (4) ukuba namandla aphezulu okudinwa; (5) ukuba nokumelana okuphezulu kokuguguleka; (6) ukuba nokuqina okuphezulu kunye nokufunxwa okungcono komthwalo wempembelelo; (7) ubukhulu bejometri ukuhlangabezana nomzobo.
3. Inkqubo yokuvelisa ikhonkco lemigodi
Inkqubo yokuvelisa uthotho lwemigodi: ukusika iibha → ukugoba nokuluka → ijoyinti → ukuwelda → uvavanyo lobungqina bokuqala → unyango lobushushu → uvavanyo lobungqina besibini → ukuhlolwa. Ukuwelda kunye nonyango lobushushu ziinkqubo eziphambili ekuvelisweni kwekhonkco lekhonkco elijikelezileyo lemigodi, ezichaphazela ngqo umgangatho wemveliso. Iiparamitha zokuwelda zesayensi zinokuphucula isivuno kwaye zinciphise iindleko zemveliso; inkqubo efanelekileyo yokunyanga ubushushu inokunika ukudlala okupheleleyo kwiimpawu zezinto kwaye iphucule umgangatho wemveliso.
Ukuqinisekisa umgangatho wokuwelda kwetyathanga lokumba, ukuwelda kwe-arc ngesandla kunye nokuwelda kwe-resistance butt kuye kwasuswa. Ukuwelda kwe-Flash butt kusetyenziswa kakhulu ngenxa yeenzuzo zayo ezibalaseleyo ezifana nenqanaba eliphezulu lokuzenzekelayo, amandla aphantsi okusebenza kunye nomgangatho wemveliso ozinzileyo.
Okwangoku, unyango lobushushu lwe-mining round link chain ngokubanzi lusebenzisa ubushushu obuphakathi, ukucima okuqhubekayo kunye nokushisa. Ingongoma yobushushu obuphakathi kukuba isakhiwo se-molecular sento sishukunyiswa phantsi kwentsimi ye-electromagnetic, iimolekyuli zifumana amandla kwaye zingqubane ukuze zivelise ubushushu. Ngexesha lonyango lobushushu obuphakathi, i-inductor iqhagamshelwe kwi-AC ye-frequency ethile, kwaye iikhonkco ze-chain zihamba ngesantya esifanayo kwi-inductor. Ngale ndlela, umbane obangelwayo one-frequency efanayo kunye necala elichaseneyo ne-inductor uya kuveliswa kwiikhonkco ze-chain, ukuze amandla ombane aguqulwe abe ngamandla obushushu, kwaye iikhonkco ze-chain zinokufudunyezwa kubushushu obufunekayo bokucima kunye nokushisa ngexesha elifutshane.
Ukufudumeza okuphakathi kokungenisa i-induction kunesantya esikhawulezayo kwaye kuncinci ukuxinana. Emva kokucinywa, isakhiwo esincinci kakhulu sokucinywa kunye nobukhulu be-austenite grain bunokufunyanwa, nto leyo ephucula amandla kunye nokuqina kwekhonkco le-chain. Kwangaxeshanye, ikwanazo neengenelo zokucoceka, ucoceko, ukulungiswa okulula kunye nokusebenza kakuhle kwemveliso. Kwinqanaba lokuxinwa, indawo yokuxinwa kwekhonkco le-chain idlula kubushushu obuphezulu bokuxinwa kwaye isusa uxinzelelo olukhulu lwangaphakathi lokucima ngexesha elifutshane, olunefuthe elibalulekileyo ekuphuculeni ubungqingqwa kunye nokuqina kwendawo yokuxinwa kunye nokulibazisa ukuqaliswa kunye nophuhliso lweentanda. Ubushushu bokuxinwa phezulu kwegxalaba lekhonkco le-chain buphantsi, kwaye bunobunzima obuphezulu emva kokuxinwa, nto leyo enceda ekugugeni kwekhonkco lekhonkco ngexesha lenkqubo yokusebenza, oko kukuthi, ukuguguleka phakathi kweekhonkco zekhonkco kunye nokuxinana phakathi kweekhonkco zekhonkco kunye ne-sprocket yekhonkco.
4. Isiphelo
(1) Intsimbi yokumba ikhonkco elijikelezileyo elinamandla aphezulu iphuhliswa kwicala lokuqina okuphezulu, ukuqina okuphezulu, ukuqina okuphezulu kweplastiki kunye nokumelana nokugqwala kunentsimbi ye-23MnNiMoCr54 esetyenziswa kakhulu kwihlabathi liphela. Okwangoku, kuye kwasetyenziswa amanqanaba entsimbi amatsha nanelungelo elilodwa lomenzi.
(2) Ukuphuculwa kweempawu zoomatshini ze-mining high-strength round link chain kukhuthaza ukuphuculwa okuqhubekayo kunye nokugqibelela kwendlela yokunyanga ubushushu.
