Imbono yoBugcisa
1. Umthetho Wokuhlala Uqinile
Ukuthembeka kubaluleke kakhulu kwimigodi ye-longwall, apho ukusilela okunxulumene ne-AFC kuyimbangela ephambili yokungasebenzi kakuhle okungacwangciswanga, okubangela malunga ne-27% yokumiswa kwemveliso iyonke. Ingongoma yalo mceli mngeni ikukukhetha ityathanga elifanelekileyo lokusetyenziswa. Ityathanga lisebenza phantsi komthwalo onzima ojikelezayo, ukuguguleka okurhabaxa, kunye neemeko zokubola, okwenza ukuqina kube ngumsebenzi woyilo, izinto, kunye nendawo yokusebenza. Eli phepha lihlalutya iimpawu zokuqina kwangaphakathi zeentlobo eziphambili zetyathanga ukuze kunikwe iingcebiso ezingcono zokuthenga kunye nezigqibo zokusebenza.
Iitsheyini zomgodi wamalahle waseLongwallzisetyenziswa kwiiArmored Face Conveyors (ii-AFC). Njengoko ishishini liqhubeka litshintsha,uthotho lwekhonkco olujikelezayo (DIN 22252)iye yaphuhliswa ukuze ithathelwe indawo kakhulu zizinye iindlela zanamhlanje ezifanaiintambo zekhonkco ezithe tyaba (DIN 22255)kunye noyilo oluphambili lwe-"Ultra-Flat" okanye "Solid Profile". Ziyahluka ngeendlela zokusilela, iiparameter zokusebenza, kunye nomjikelo wobomi bonke, nto leyo eyenza ukuba kube yimfuneko ekukhetheni ityathanga elifanelekileyo kwimisebenzi enzima yodonga olude.
2. Uthelekiso loYilo lweTyeya: Ijiyometri kunye neendlela zokusilela
Ijiyometri esisiseko yetsheyini ilawula ngokuthe ngqo usasazo lwayo loxinzelelo, ipateni yokuguguleka, kunye neendlela zokusilela okuphambili. Itheyibhile engezantsi ishwankathela iimpawu eziphambili:
| Ipharamitha yoYilo | Ikhonkco leeNkcukacha ezijikelezileyo (DIN 22252) | Ikhonkco eliQhelekileyo eliQhelekileyo (DIN 22255) | Ikhonkco leProfayili eliPhambili eliGqibeleleyo/eliqinileyo |
| Umgangatho oPhambili | I-DIN 22252 | I-DIN 22255 | Uyilo lwempahla (umz., "Iprofayili Eyintloko") |
| Amandla Okuqina Okubalulekileyo | Uyilo olulinganayo noluguquguqukayo; ukuqina okuphezulu kokufunxa iimpembelelo. | Ukuphakama okuphantsi ngokubanzi kuvumela iprofayili yepani enciphileyo kunye nomthamo womthwalo owandisiweyo. | Umphezulu woqhagamshelwano ophezulu unciphisa uxinzelelo kunye nokuguguleka kweyunithi; i-geometry ithintela ukuxinana. |
| Ubuthathaka obuPhambili boKuhlala ixesha elide | Indawo encinci yokunxibelelana phakathi kweekhonkco ikhokelela kuxinzelelo olukhulu kakhulu lokunxibelelana kunye nokuguguleka kwendawo ethile. | Uxinzelelo lugxila emagxeni eekhonkco kunye namazinyo eekhonkco; iikhonkco ziindawo ezibuthathaka kakhulu. | Ubunzima obukhulu bokuvelisa; kunokufuna ii-sprockets okanye izinto ezikhethekileyo. |
| Indlela yokuNxiba/yokuHlehla ePhambili | Ukuguguleka okurhabaxa kwiindawo ezincinci zokudibana, okukhokelela ekulahlekelweni kwamacandelo kunye nemijikelo "yokuguguleka nokudinwa". | Ukudinwa okubangelwa kukuqhekeka kwamalungu omzimba okubangelwa kukudinwa okubangelwa kukwaphuka kwamalungu omzimba kwiindawo ezixinezelekileyo (izihlanganisi, amagxa) phantsi komthwalo ojikelezayo. | Ukunciphisa ukuguguleka ngokubanzi; yenzelwe ukunciphisa ukungqubana kwe-martensite kunye nobude. |
3. Izinto Ezihlala Ziqinile Ngaphaya Koyilo Olusisiseko
Ukuqina akubonakali kuphela ngesimo sekhonkco. Izinto ezininzi ezixhomekeke kwenye zidlala indima ebalulekileyo:
- Isayensi yezinto ezisetyenzisiweyo kunye neMetallurgy: Ukuqhubela phambili kwizinto ezixutyiweyo (Cr, Ni, Mn, Mo) kunye nonyango oluphezulu lobushushu (ukucima kunye nokushisa) kunokunyusa ukumelana nokuguguleka nge-10-25%. Iintsimbi eziphezulu ezifana ne-23MnNiCrMo54 zisetyenziselwa ukufezekisa imithwalo ephezulu yokuphuka kunye nobomi bokudinwa.
- Ukuthembeka kweConnector: Kwiinkqubo ze-flat link, i-connector idla ngokuba yeyona connector ibuthathaka. Ukulungisa i-connector tooth geometry ukuze kubekho usasazo olulinganayo lwe-stress kubaluleke kakhulu kubomi benkqubo iyonke.
- Ukukhusela Ukugqwala: Ukugqwala kukhawulezisa ukuguguleka nokudinwa. Iingubo zokukhusela eziphambili, ezifana ne-zinc-nickel plating, zinokwandisa ixesha ukuya kwi-red-rust izihlandlo ezininzi xa kuthelekiswa nokugqitywa kwendabuko, ziphucula ngokuthe ngqo ubomi betsheyini kwiimeko ezimanzi.
- Iindlela Zokusebenza: Uxinzelelo olufanelekileyo lubalulekile. Uxinzelelo olungaphantsi lubangela ukudinwa nokuchachamba, ngelixa uxinzelelo olungaphezulu lukhawulezisa kakhulu ukuguguleka nokudinwa. Ukuhlolwa rhoqo kwe-sprocket nako kubalulekile, njengoko ii-sprocket ezigugileyo ziya konakalisa nayiphi na ityathanga ngaphambi kwexesha.
4. Isakhelo soKhetho: Ukufanisa iTyeya neSicelo
Akukho tyathanga "eligqibeleleyo" lilonke, kodwa kukho tyathanga elifanelekileyo kwiimeko ezithile. Ukukhetha kufuneka kube yinkqubo yokusebenzisana phakathi komgodi kunye nomenzi.
- KhethaIintambo zeRound Link (DIN 22252)xa: Eyona nto iphambili kukuguquguquka okuphezulu kunye nokufunxwa kwempembelelo kwiimeko ezinzima nezingenakulinganiswa zomthungo. Uyilo lwazo olulinganayo luyaxolela xa kusetyenziswe izinto apho kunokubakho ukungalungelelani okanye ukujija.
- Khetha iStandardIiTyathanga zeFlat Link (DIN 22255)xa: Kukho imida yokuphakama kweConveyor, kwaye iprofayili yepani esezantsi iyafuneka ukwandisa umthamo. Ziyindlela ethe ngqo yokulungisa iinkqubo zekhonkco ezijikelezileyo ngaphandle kotshintsho olukhulu kwi-pan line.
- Khetha iiTsheyini eziPhambili ze-"Ultra-Flat" okanye "Solid Profile" xa: Injongo yokusebenza kukwandisa ubomi benkonzo kunye nokunciphisa ixesha lokungasebenzi kwizicelo ezinamandla aphezulu, ezithwala iitoni ezininzi. I-geometry yabo yobunjineli ijolise ekusombululeni ngokuthe ngqo izizathu zokuguguleka kunye nokungaphumeleli kweetsheyini.
5. Isiphelo
Utshintsho oluvela kwi-round link ukuya kwi-advanced flat-link designs lubonisa utshintsho oluvela kwi-generalized tightness ukuya kwi-optimal wear performance. Ngelixa ii-round links zibonelela ngokuguquguquka okuqinileyo, ii-flat kunye nee-ultra-flat chains zibonelela ngezisombululo ezicwangcisiweyo zokwandisa umthamo kunye nobomi obude. Eyona ndlela iqinileyo sisigqibo senqanaba lenkqubo esiqwalasela i-geometry, umgangatho wezinto, uyilo lwe-connector, ukugqitywa kokukhusela, kunye—ngokubalulekileyo—nokugcinwa okufanelekileyo kokusebenza. Ekugqibeleni, ukutyala imali kwi-chain "efaneleke ngokupheleleyo kwiimeko ezithile" kwaye ixhaswa yintsebenziswano yobuchwephesha bengcali yeyona ndlela isebenzayo yokwandisa ixesha lokusebenza kunye nemveliso ye-longwall conveyor.
