I-track shoe ingenye ye i-undercarriage izingxenye zemishini yokwakha kanye nengxenye esengozini yemishini yokwakha esetshenziswayo.Kube cesetshenziswa ngokujwayelekile emishinini yokwakha efana ne-excavators, ama-bulldozer, ama-crawler cranes, nama-pavers.
Isakhiwo seithrekhi izicathulo
Izicathulo zethrekhi ezijwayelekile zihlukaniswa zibe izinhlobo ezintathu ngokusho kokwakheka komhlaba, ubambo olulodwa, izimbambo ezintathu kanye ne-flat-bottomed, kanti ezinye zazo zisebenzisa izicathulo zethrekhi ezingunxantathu.Izicathulo zethrekhi eziqinisiwe zodwa zisetshenziselwa ikakhulukazi ama-bulldozers nogandaganda, ngoba imishini enjalo idinga izicathulo zethrekhi ukuze zibe namandla aphezulu okudonsa.Nokho, akuvamile ukusetshenziswa kuma-excavators.Lolu hlobo lwesicathulo sethrekhi lusetshenziswa kuphela uma i-excavator ifakwe ifreyimu yokubhoboza noma idinga i-thrust enkulu evundlile.Amandla okudonsa aphezulu ayadingeka lapho uphenduka, ngakho-ke amabha okunyathela aphakeme (okungukuthi, ama-spurs) azompintsha inhlabathi (noma umhlabathi) phakathi kwezigxobo zokunyathela, ngaleyo ndlela kube nomthelela ekusebenzeni kwe-excavator.
Izicathulo zethrekhi yensimbi zingahlukaniswa zibe: amapuleti e-excavator namapuleti kagandaganda, lezi ezimbili zisetshenziswa kakhulu, ezinensimbi yesigaba njengento eluhlaza.Bese kuba nephansi elimanzi elisetshenziswa amagandaganda, aziwa kakhulu ngokuthi “ipuleti elingunxantathu”, okuyipuleti elikhonjiwe.Olunye uhlobo lwe-cast plate lusetshenziswa kuma-crawler cranes.Isisindo saleli puleti sisukela emashumini amakhilogremu kuya kumakhulu amakhilogremu.
Insimbi esikhundleniithrekhi izicathulo
Izicathulo zethrekhi zezimoto ezilandelwayo ngokuvamile zenziwe ngensimbi ephezulu ye-manganese enomlando cishe weminyaka eyi-100.Lokhu kungenxa yokuthi insimbi ephezulu ye-manganese inesici esivelele, okungukuthi, ithola ukuqina komthelela ngaphansi kwesenzo somthwalo womthelela, ukuze yakhe ungqimba olungaphezulu oluqinile futhi olungagugi, kuyilapho igcina ukuqina kanye nepulasitiki yesakhiwo sayo sangaphakathi.Kodwa-ke, insimbi ephezulu ye-manganese isetshenziswa njengesicathulo sethrekhi, futhi ivamise ukulinyazwa kusenesikhathi ngenxa yokuqhekeka, amazinyo ahlanekezelwe kanye nokuphambuka ngesikhathi sokusetshenziswa, futhi impilo yayo yesevisi iphansi.Ukuze unqobe lokhu kushiyeka, insimbi ye-30SiMnMoV(Ti) enengxubevange ephansi enamandla amakhulu esekelwe ezinsizeni zasekhaya futhi kulula ukuyikhiqiza.Isetshenziswe ngempumelelo esikhundleni sensimbi ye-manganese ephezulu ukwenza izicathulo zethrekhi.
Indlela yokucubungula
Ubuchwepheshe bokucubungula izicathulo zethrekhi yephrofayili ngokuvamile: ukusebenzisa ukuvala iphrofayili, ukubhoboza (ukubhoboza), ukwelashwa kokushisa, ukuqondisa, ukudweba nezinye izinqubo;ithrekhi ye-bulldozer iqiniswe eyodwa, futhi umbala wepende jikelele uphuzi;ipuleti le-excavator ngokuvamile Liyizimbambo ezintathu, futhi umbala wepende umnyama.Iphrofayili ethengiwe ngokuvamile ingu-25MnB, futhi ubulukhuni bokugcina bokwelashwa kokushisa kwento esebenzayo yi-HB364~444.
