Umbono Wezobuchwepheshe
1. Ukuqina Okubalulekile
Ukuthembeka kubaluleke kakhulu ekuvuneni kwe-longwall, lapho ukwehluleka okuhlobene ne-AFC kuyimbangela ehamba phambili yokungasebenzi kahle okungahleliwe, okubangela cishe u-27% wokumiswa kokukhiqiza okuphelele. Ingqikithi yale nselele itholakala ekukhetheni uchungechunge olufanele lokusetshenziswa. Amaketanga asebenza ngaphansi komthwalo onzima wokujikeleza, ukuguguleka okubuhlungu, kanye nezimo zokugqwala, okwenza ukuqina kube umsebenzi womklamo, izinto zokwakha, kanye nendawo yokusebenza. Leli phepha lihlaziya izici zokuqina kwangaphakathi zezinhlobo ezinkulu zamaketanga ukuze linikeze ulwazi ngezinqumo zokuthenga nezokusebenza ezingcono.
Amaketanga emayini yamalahle e-longwallzisetshenziswa kuma-Armored Face Conveyors (ama-AFC). Njengoba imboni ithuthuka,uchungechunge lwezixhumanisi oluyindilinga (DIN 22252)isithuthuke kakhulu ukuze ithathelwe indawo ezinye izindlela zesimanje ezifanaamaketanga ezixhumanisi ezisicaba (DIN 22255)kanye nemiklamo ethuthukisiwe ye-"Ultra-Flat" noma "Solid Profile". Ziyahlukahluka ngezindlela zokwehluleka, amapharamitha okusebenza, kanye nomjikelezo wokuphila okuphelele, okwenza kube yinto ebalulekile ekukhetheni uchungechunge oluhle kakhulu ekusebenzeni okudingakalayo kwezindonga ezinde.
2. Ukuqhathaniswa Komklamo Weketanga: Ijiyometri Nezindlela Zokwehluleka
I-geometry eyisisekelo yeketanga inquma ngqo ukusatshalaliswa kwayo kokucindezeleka, iphethini yokuguguleka, kanye nezindlela zokuhluleka okuyinhloko. Ithebula elingezansi lifingqa izici ezibalulekile:
| Ipharamitha Yokuklama | Uchungechunge Lwezixhumanisi Eziyindilinga (DIN 22252) | Uchungechunge Olujwayelekile Lwesixhumanisi Esiyisicaba (DIN 22255) | Uchungechunge Lwephrofayili Oluthuthukisiwe Oluyindilinga/Oluqinile |
| Izinga Eliyinhloko | I-DIN 22252 | I-DIN 22255 | Imiklamo yobunini (isb., "Iphrofayili Eyinhloko") |
| Amandla Okuqina Okubalulekile | Idizayini elinganayo neguquguqukayo; ukuqina okuphezulu kokumunca imithelela. | Ukuphakama okuphansi kuvumela iphrofayili yepani encishisiwe kanye nomthamo womthwalo owandisiwe. | Indawo yokuxhumana ephezulu inciphisa ingcindezi kanye nokuguguleka kweyunithi; i-geometry ivimbela ukuminyana. |
| Ubuthakathaka Bokuqina Okubalulekile | Indawo encane yokuxhumana exhumanisayo iholela ekucindezelekeni okukhulu kakhulu kokuxhumana kanye nokuguguleka kwendawo. | Ukucindezeleka kugxila emahlombe okuxhumanisa kanye namazinyo okuxhumanisa; izixhumi ziyizindawo ezibuthakathaka kakhulu. | Ubunzima obukhulu bokukhiqiza; kungadinga ama-sprocket noma izingxenye ezikhethekile. |
| Imodi Yokugqokwa/Yokwehluleka Okuyinhloko | Ukuguguleka okukhuhlayo ezindaweni ezincane zokuthintana, okuholela ekulahlekelweni kwezingxenye kanye nemijikelezo "yokuguguleka nokukhathala". | Ukuphuka kokukhathala kuqala ezindaweni ezixinene kakhulu (izixhumi, amahlombe) ngaphansi komthwalo ojikelezayo. | Ukunciphisa ukuguguleka okuvamile; kwenzelwe ukunciphisa ukungqubuzana kwe-martensite kanye nokwelulwa. |
3. Izici Zokuqina Ngaphandle Komklamo Oyisisekelo
Ukuqina akuchazi kuphela ngesimo sesixhumanisi. Izici eziningana ezincike komunye nomunye zidlala indima ebalulekile:
- Isayensi Yezinto Ezibalulekile kanye Nensimbi: Intuthuko ezintweni ezixubayo (i-Cr, i-Ni, i-Mn, i-Mo) kanye nokwelashwa kokushisa okulungiselelwe kahle (ukucima nokushisa) kungathuthukisa ukumelana nokuguguleka ngo-10-25%. Izinsimbi zezinga eliphezulu njenge-23MnNiCrMo54 zisetshenziselwa ukufeza imithwalo yokuphuka engcono kakhulu kanye nokuphila kokukhathala.
- Ukuthembeka Kwesixhumi: Kumasistimu ezixhumanisi ezisicaba, isixhumi sivame ukuba yisixhumanisi esibuthakathaka kakhulu. Ukuthuthukisa i-geometry yamazinyo esixhumi ukuze kusatshalaliswe ukucindezeleka okulinganayo kubaluleke kakhulu empilweni yesistimu iyonke.
- Ukuvikelwa Kokugqwala: Ukugqwala kusheshisa ukuguguleka nokukhathala. Izembozo ezithuthukisiwe zokuvikela, njenge-zinc-nickel plating, zingandisa isikhathi sibe ukugqwala okubomvu izikhathi eziningana uma kuqhathaniswa nokuqedwa kwendabuko, zithuthukise ngqo impilo yeketanga ezimweni ezimanzi.
- Imikhuba Yokusebenza: Ukucindezela okufanele kubalulekile. Ukucindezela okungaphansi kwengcindezi kubangela ukuxega nokushaqeka, kuyilapho ukucindezela ngokweqile kusheshisa kakhulu ukuguguleka nokukhathala. Ukuhlolwa njalo kwe-sprocket nakho kubalulekile, njengoba ama-sprocket agugile azolimaza noma yiluphi uchungechunge ngaphambi kwesikhathi.
4. Uhlaka Lokukhetha: Ukufanisa Uchungechunge Nohlelo Lokusebenza
Akukho uchungechunge "oluphelele" olukhona emhlabeni wonke, kodwa kukhona uchungechunge olufanele izimo ezithile. Ukukhetha kufanele kube inqubo yokubambisana phakathi kwemayini nomkhiqizi.
- KhethaAmaketanga Ezixhumanisi Eziyindilinga (DIN 22252)uma: Okubaluleke kakhulu ukuguquguquka okuphezulu kanye nokumuncwa komthelela ezimweni ezinzima nezingenakulinganiswa zomthungo. Ukwakheka kwazo okulinganayo kuyathethelela lapho kungase kwenzeke khona ukungalungi noma ukusonteka.
- Khetha OkujwayelekileAmaketanga E-Flat Link (DIN 22255)uma: Kukhona imikhawulo yokuphakama kwe-Conveyor, futhi kudingeka iphrofayili yepani engezansi ukuze kwandiswe umthamo. Ziyindlela yokulungisa ngqo izinhlelo zezixhumanisi eziyindilinga ngaphandle kokuguqulwa okukhulu kwemigqa yepani.
- Khetha Amaketanga Athuthukisiwe "E-Ultra-Flat" noma "E-Solid Profile" lapho: Umgomo wokusebenza uwukukhulisa impilo yesevisi nokunciphisa isikhathi sokungasebenzi ezinhlelweni zokusebenza ezinamandla aphezulu, ezinamathani amaningi. I-geometry yabo ethuthukisiwe ihlose ukubhekana ngqo nezimbangela zokuguguleka kanye nokwehluleka kweketanga.
5. Isiphetho
Ukuvela kwesakhiwo se-round link kuya kwesakhiwo se-flat-link esithuthukisiwe kumelela ushintsho kusuka ekuqineni okujwayelekile kuya ekusebenzeni kahle kokuguguleka. Ngenkathi izixhumanisi ezizungezile zinikeza ukuguquguquka okuqinile, izintambo ezisicaba nezisicaba kakhulu zinikeza izixazululo eziklanywe ngobunjiniyela zokwandisa umthamo kanye nokuphila isikhathi eside. Ukukhetha okuhlala isikhathi eside kakhulu yisinqumo sezinga lesistimu esibheka i-geometry, ikhwalithi yezinto ezibonakalayo, ukwakheka kwesixhumi, ukuqeda okuvikelayo, kanye—ngokubalulekile—nokugcinwa kokusebenza okufanele. Ekugcineni, ukutshala imali kuchungechunge "olufanele ngokuphelele izimo ezithile" futhi olusekelwa ukubambisana kobuchwepheshe obuchwepheshile kuyisu eliphumelela kakhulu lokukhulisa isikhathi sokusebenza kanye nokukhiqiza kwe-longwall conveyor.
