Kwimisebenzi ye-longwall, ixesha lokungasebenzi kwe-conveyor elingalindelekanga lutshaba lokuvelisa. Nangona ukungaphumeleli kunokubonakala ngequbuliso, kudla ngokubangelwa ziingxaki zoomatshini ezinokuthintelwa. Ezibini zezona ndawo zibalulekileyo ekufuneka kugxilwe kuzo yingxaki eqhubekayo "yokuxhuzula" kwetyathanga kunye nesiqhelo esisisiseko sokugcinwa kwetyathanga ngokukhawuleza. Ukuqonda nokujongana nezi zinto kunokuphucula kakhulu ukuthembeka kunye nobomi bomthumeli wakho.
Ingxaki yeChain "Knuckling"
Indlela ethile neyonakalisayo yokusilela kwii-longwall conveyors yaziwa ngokuba yi-"knuckling." Oku kwenzeka xa ikhonkco elijikelezayo le-conveyor chain lijikeleza ngokuthe nkqo, lime kwi-90° ukuya kwindawo yalo eqhelekileyo ethe tye. Xa sele ikwindawo ethe nkqo, ikhonkco linokuwa ngqo phambi kwe-flight bar (scraper). Oku kuyayixina ikhonkco ngokufanelekileyo emzimbeni we-flight bar, kuyithintela ekujikeni ibuyele kwindawo yayo echanekileyo kwaye ibangele ukuvalelwa kwenkqubo ngokupheleleyo.
Isiphumo kukuba kumiswe ngokukhawuleza, ngendlela eyingozi kakhulu ebeka emngciphekweni umonakalo omkhulu kwitsheyini, kwiibhari zokubhabha, nakwii-sprockets. Ukuyisombulula kufuna ukungenelela okukhulu ngesandla, nto leyo ekhokelela kwixesha lokungasebenzi elibizayo.
Isisombululo soBunjineli: Izinto ezichasene namaqhina
Isisombululo sale ngxaki sisakhiwo sobunjineli esilula kodwa esomeleleyo: i-anti-knuckle insert. Njengoko kuchaziwe kwiipatenti zoshishino lwezemigodi, esi sixhobo sisixhobo se-polymer esiyilelwe ngokukodwa ukungena ngaphakathi kwindawo evulekileyo esembindini wekhonkco leetyathanga.
Yenziwe nge-thermoplastic eqinileyo nehlala ixesha elide, i-insert ilinganiswa ukuba ibe banzi kancinci kunokuphakama kwangaphakathi kwe-link. Ngexesha lokufakwa, iyacinezelwa ize ifakwe phakathi kwamacala ahambelanayo e-link. Yakuba ikwindawo yayo, ibuyela kwimo yayo yokuqala, izitshixe ngokukhuselekileyo kwiindonga zangaphakathi ze-link. Ukuze kubekho ukhuseleko olongezelelekileyo, i-pin yokutshixa idla ngokuqhutywa nge-insert ukuze ithintele ukuba ingawi phantsi kwemithwalo enzima.
Ngokuzalisa isithuba ngaphakathi kwekhonkco, i-insert ithintela ngokwasemzimbeni i-chain ukuba ingajikelezi iye kwindawo ethe nkqo "edibeneyo", ngaloo ndlela isusa unobangela we-jam.
Ulondolozo Lokuthintela Olusisiseko: Umgca Wakho Wokuqala Wokuzikhusela
Nangona izisombululo ezifana ne-anti-knuckle inserts zijongana nokusilela okuthile, inkqubo yokukhusela engqongqo yeyona nto iphambili kwimpilo yokuhambisa i-longwall. Izifundo zoshishino zibonise ukuba ipesenti enkulu yexesha lokungasebenzi kwe-longwall—ebalelwa kwi-27% kwimigodi kwelinye uphando olukhulu—inxulumene nokusilela kwe-chain, kwaye uxinzelelo olungafanelekanga lwe-chain luyimbangela ephambili.
Nazi iintsika eziphambili zesicwangciso sokukhusela esisebenzayo:
1. Uxinzelelo lweChain eyi-Master kunye ne-Slack
Uxinzelelo olufanelekileyo lwetyathanga lusenokuba lolona phawu lubalulekileyo lolondolozo. Uxinzelelo olugqithisileyo luyimbangela ephambili yomonakalo, okuvumela ityathanga ukuba liqokelelene, litsibe ii-sprockets, kwaye liphume. Ngokwahlukileyo koko, ityathanga eliqinileyo kakhulu likhawulezisa ukuguguleka kwe-interlink kunye nomonakalo we-sprocket. Injongo kukugcina uxinzelelo lwangaphambi koxinzelelo oluthintela ukugoba phantsi komthwalo ngaphandle kokudala uxinzelelo olugqithisileyo. Linganisa kwaye ulungise uxinzelelo rhoqo usebenzisa imitha yoxinzelelo elinganisiweyo, kwaye ususe ityathanga loxinzelelo kwiindlela ezincinci, ezilawulwayo (umz., iikhonkco ezimbini ngexesha).
2. Jonga kwaye ulinganise ubude beTyeya
Itsheyini ayisoluli ngokwenene; iyakhula ngenxa yokonakala kwekhonkco kwiindawo zoqhagamshelwano. Ukujonga olu longezelelo yindlela ethe ngqo yokulinganisa impilo yetsheyini kunye nobomi obuseleyo. Sebenzisa i-caliper yetsheyini ukulinganisa rhoqo ubude bepitch obubekiweyo. Njengesikhokelo esiqhelekileyo, iitsheyini zinokuthathelwa ingqalelo ukuba zitshintshwe xa ulongezelelo ludlula i-3%, nangona imisebenzi emininzi ibeka umda ozinzileyo we-2%.
3. Sebenzisa inkqubo yovavanyo oluqatha
Ukuhlolwa okucwangcisiweyo kokubona nokujonga ngokwasemzimbeni kunokuthintela iingxaki ezincinci ngaphambi kokuba ziqhubeke. Uluhlu lwakho lokuhlola kufuneka luquke:
- Ii-Sprockets: Jonga amazinyo agugileyo, aqhekekileyo, okanye anqunyulweyo. Ii-sprockets ezigugileyo zikhawulezisa ukuguguleka kweetyathanga kwaye zinokubangela ukubandakanyeka okungafanelekanga.
- Ulungelelwaniso: Qinisekisa ukuba ii-sprockets, ii-conveyor pans, kunye nomgca wobuso wonke zilungelelaniswe ngokuchanekileyo. Umgca wobuso ongalunganga ukhokelela ekuxinezelekeni okungalinganiyo kunye nokuguguleka okwahlukileyo phakathi kwemicu yetyathanga.
- Uqhagamshelo kunye nolwakhiwo: Qinisa zonke iinati zoqhagamshelo ezikhululekileyo kunye neekhamandela, kwaye utshintshe iibholiti zoqhagamshelo zepani ezilahlekileyo. Hlola iipani ezonakeleyo okanye imicu egugileyo enokukhokelela ekulahlekeni kwekhonkco.
4. Sebenzisa uMgaqo-nkqubo woTshintsho oluSebenzayo
Musa ukuqhuba izinto zingasebenzi. Misela iikhrayitheriya ezicacileyo nezisekelwe kwidatha zokutshintsha iipayina zetyathanga kunye nee-sprockets ngokusekelwe kumlinganiselo wobude kunye nokuguguleka kwe-sprocket. Ukusebenzisa ityathanga eligugileyo kakhulu eline-sprockets ezintsha (okanye ngokuchaseneyo) kukhokelela kumonakalo okhawulezileyo nokhawulezileyo kuzo zombini.
Ngokudibanisa izisombululo zobunjineli ezijolise kuzo kwiindlela ezaziwayo zokusilela ezifana nokuknuckling kunye nenkcubeko yokugcinwa eqeqeshwe kakuhle, enolwazi ngedatha, imisebenzi inokuguqula i-longwall conveyor yayo ukusuka kumthombo wexesha lokungasebenzi ibe yintsika yemveliso enoqikelelo, enomthamo omkhulu.
