Emisebenzini ye-longwall, ukungasebenzi kwe-conveyor okungalindelekile kuyisitha sokukhiqiza. Nakuba ukwehluleka kungabonakala kungazelelwe, kuvame ukubangelwa izinkinga zemishini ezingavinjelwa. Izindawo ezimbili ezibaluleke kakhulu okufanele kugxilwe kuzo yinkinga eqhubekayo "yokugoba" kweketanga kanye nomkhuba oyisisekelo wokunakekelwa kweketanga okusebenzayo. Ukuqonda nokubhekana nalokhu kungathuthukisa kakhulu ukuthembeka kanye nokuphila kwesikhathi kwe-conveyor yakho.
Inkinga Yokugoba Kwe-Chain
Imodi yokuhluleka ethize nelimazayo kuma-conveyor e-longwall yaziwa ngokuthi "i-knuckling." Lokhu kwenzeka lapho isixhumanisi esiyindilinga se-conveyor chain sijikeleza siqonde phezulu, sime ku-90° endaweni yaso evamile evundlile. Uma sesikulesi simo esiqondile, isixhumanisi singawela ngqo phambi kwebha yendiza (i-scraper). Lokhu kuvimbela ngempumelelo isixhumanisi emzimbeni webha yendiza, kusivimbele ukuthi sibuyele emuva ekuqondeni kwaso okulungile futhi kubangele ukuvalelwa okuphelele kwesistimu.
Umphumela uba ukumiswa okusheshayo nokuyinhlekelele okubangela umonakalo omkhulu kuketanga, imigoqo yokundiza, kanye nama-sprocket. Ukuxazululwa kwalokhu kudinga ukungenelela okukhulu ngesandla, okuholela esikhathini sokungasebenzi esibizayo.
Isixazululo Sobunjiniyela: Ukufakwa Okulwa Nama-Knuckle
Isixazululo sale nkinga siwumklamo wobunjiniyela olula kodwa oqinile: i-anti-knuckle insert. Njengoba kuchazwe kumalungelo obunikazi embonini yezimayini, le divayisi iyi-polymer insert eyenzelwe ngqo ukungena ngaphakathi kwendawo evulekile ephakathi yesixhumanisi seketanga.
Yenziwe nge-thermoplastic eqinile neqinile, i-insert ilinganiswa ukuthi ibe banzi kancane kunokuphakama kwangaphakathi kwesixhumanisi. Ngesikhathi sokufakwa, iyacindezelwa futhi ifakwe phakathi kwezinhlangothi ezihambisanayo zesixhumanisi. Uma isisendaweni yayo, ibuyela esimweni sayo sokuqala, izikhiyele ngokuphephile ezindongeni zangaphakathi zesixhumanisi. Ukuze kuvikelwe okwengeziwe, iphini yokukhiya ivame ukudonswa nge-insert ukuze ivimbele ukuthi ingawi ngaphansi kwemithwalo enzima.
Ngokugcwalisa isikhala ngaphakathi kwesixhumanisi, i-insert ivimbela ngokomzimba iketanga ukuthi lingajikelezi liye endaweni "egobile" eqondile, ngaleyo ndlela isuse imbangela yejamu.
Ukugcinwa Kokuvimbela Okuyisisekelo: Umugqa Wakho Wokuqala Wokuzivikela
Nakuba izixazululo ezifana ne-anti-knuckle inserts zibhekana nokwehluleka okuthile, uhlelo lokulungisa oluqinile lokuvimbela luyisisekelo sempilo yokuthutha i-longwall. Izifundo zemboni zibonise ukuthi iphesenti elikhulu lokungasebenzi kwe-longwall—okuyi-27% ezimayini kwesinye isifundo esikhulu—lihlobene nokwehluleka kwe-chain, kanti ukungezwani okungafanele kwe-chain kuyimbangela ehamba phambili.
Nazi izisekelo eziyinhloko zesu lokulungisa eliphumelelayo lokuvimbela:
1. Ukucindezeleka Kwe-Master Chain kanye ne-Slack
Ukucindezeleka okufanele kweketanga kungenye yezinto ezibaluleke kakhulu ekunakekelweni. Ukucindezeleka ngokweqile kuyimbangela eyinhloko yomonakalo, okuvumela ukuthi iketanga lihlangane, ligxume ama-sprocket, futhi liphume emzileni. Ngokuphambene nalokho, iketanga eliqinile kakhulu lisheshisa ukuguguleka kwezixhumanisi kanye nomonakalo we-sprocket. Umgomo ukugcina ukucindezeleka kwangaphambi kokucindezeleka okuvimbela ukucindezeleka ngaphansi komthwalo ngaphandle kokudala ukucindezeleka okukhulu. Kala njalo futhi ulungise ukucindezeleka usebenzisa imitha yokucindezeleka elinganisiwe, bese ususa iketanga eliqinile ngezinyuko ezincane, ezilawulwayo (isb., izixhumanisi ezimbili ngesikhathi).
2. Qapha futhi Ulinganise Ukwandiswa Kweketanga
Iketanga aliluli ngempela; liyanwebeka ngenxa yokuguga kwezixhumanisi ezindaweni zokuthintana. Ukuqapha lokhu kunwebeka kuyindlela eqondile yokulinganisa impilo yeketanga kanye nokuphila okusele. Sebenzisa i-caliper yeketanga ukuze ulinganise njalo ubude bephimbo elibekiwe. Njengesiqondiso esijwayelekile, amaketanga angacatshangelwa ukushintshwa lapho ukunwebeka kudlula u-3%, yize imisebenzi eminingi ibeka umkhawulo olondolozeka kakhulu ongu-2%.
3. Qinisekisa Umkhuba Wokuhlola Oqinile
Ukuhlolwa okuhleliwe okubonakalayo nokubonakalayo kungabamba izinkinga ezincane ngaphambi kokuba zikhule. Uhlu lwakho lokuhlola kufanele lufake:
- Ama-Sprocket: Hlola ukuthi amazinyo agugile, aqhephukile, noma asikiwe. Ama-sprocket agugile asheshisa ukuguguleka kweketanga futhi angabangela ukuhlangana okungafanele.
- Ukuqondanisa: Qinisekisa ukuthi ama-sprocket, ama-conveyor pan, kanye nomugqa wobuso wonke kuqondiswe kahle. Umugqa wobuso ongemuhle uholela ekuqineni okungalingani kanye nokuguguleka okuhlukile phakathi kwemicu yeketanga.
- Ukuxhumana kanye nesakhiwo: Qinisa wonke ama-connector nuts nama-shackles akhululekile, bese ushintsha ama-bolts axhumanisa ipani angekho. Hlola ama-pan abonakele noma imichilo egugile engadukisa iketanga.
4. Sebenzisa Inqubomgomo Yokufaka Esikhundleni Esisebenzayo
Ungasebenzisi izingxenye kuze kube yilapho zehluleka. Misa izindlela ezicacile, eziqhutshwa idatha zokushintsha ama-chain pairs nama-sprocket ngokusekelwe ekulinganisweni kokunwebeka kanye nokuguguleka kwama-sprocket. Ukusebenzisa i-chain egugile kakhulu ene-sprocket entsha (noma okuphambene nalokho) kuholela ekulimaleni okusheshayo nokusheshayo kokubili.
Ngokuhlanganisa izixazululo zobunjiniyela eziqondiwe zezindlela zokwehluleka ezaziwayo njengokugoqa ngentambo kanye nesiko lokulungisa eliqondiswe kudatha, imisebenzi ingaguqula i-conveyor yayo ye-longwall isuke emthonjeni wesikhathi sokungasebenzi ibe yinsika yokukhiqiza okubikezelwayo, okuphezulu.
