Malingaliro Aukadaulo
1. Chofunika Kwambiri Chokhalitsa
Kudalirika ndikofunikira kwambiri pa migodi ya longwall, komwe kulephera kwa AFC ndi komwe kumayambitsa nthawi yosakonzekera yogwira ntchito, zomwe zimapangitsa pafupifupi 27% ya kuyimitsidwa konse kwa kupanga. Cholinga chachikulu cha vutoli ndikusankha unyolo woyenera kugwiritsa ntchito. Unyolo umagwira ntchito pansi pa katundu wovuta kwambiri, kuwonongeka kwamphamvu, komanso kuwonongeka, zomwe zimapangitsa kuti kulimba kukhale ntchito ya kapangidwe, zinthu, ndi malo ogwirira ntchito. Pepalali likusanthula mawonekedwe olimba a mitundu yayikulu ya unyolo kuti lithandizire bwino kusankha kugula ndi kuchitapo kanthu.
Ma unyolo a mgodi wa malasha wa longwallamagwiritsidwa ntchito mu Armored Face Conveyors (AFCs). Pamene mafakitale akusintha, njira yachikhalidwe yogwiritsira ntchitounyolo wozungulira wolumikizira (DIN 22252)yapangidwa kuti ilowe m'malo mwa njira zina zamakono mongaunyolo wolumikizana wosalala (DIN 22255)ndi mapangidwe apamwamba a "Ultra-Flat" kapena "Solid Profile". Amasiyana mu njira zolephera, magawo ogwirira ntchito, ndi moyo wonse, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pakusankha bwino unyolo pa ntchito zovuta za longing.
2. Kuyerekeza Kapangidwe ka Unyolo: Jiyometri ndi Njira Zolephera
Maonekedwe oyambira a unyolo amalamulira mwachindunji kugawa kwake kupsinjika, mawonekedwe ake owonongeka, ndi njira zoyambira zolephera. Gome ili pansipa likufotokoza mwachidule makhalidwe ofunikira:
| Chigawo cha Kapangidwe | Unyolo Wozungulira Wolumikizira (DIN 22252) | Unyolo Wokhazikika Wolumikizana ndi Flat (DIN 22255) | Unyolo Wotsogola Wapamwamba / Wolimba |
| Muyezo Woyamba | DIN 22252 | DIN 22255 | Mapangidwe a eni ake (monga, "Mbiri Yaikulu") |
| Mphamvu Yolimba Yofunikira | Kapangidwe kofanana, kosinthasintha; kulimba kwambiri kuti kugwire ntchito. | Kutalika kochepa kumalola kuti mbiri ya pan ikhale yochepa komanso kuti katundu achuluke. | Malo olumikizirana kwambiri amachepetsa kupsinjika ndi kuwonongeka kwa yuniti; mawonekedwe ake amaletsa kugwedezeka. |
| Kufooka Kofunika Kwambiri | Malo olumikizirana ang'onoang'ono amachititsa kuti pakhale kupsinjika kwakukulu komanso kuwonongeka kwa malo. | Kupsinjika maganizo kumayang'ana kwambiri mapewa olumikizirana ndi mano olumikizirana; zolumikizira ndi malo ofooka kwambiri. | Kupanga zinthu movutikira kwambiri; kungafunike ma sprockets kapena zigawo zina zapadera. |
| Njira Yoyamba Yovalira/Yolephera | Kuwonongeka koopsa pamalo ang'onoang'ono okhudzidwa, zomwe zimapangitsa kuti pakhale kutayika kwa ziwalo zina komanso kutopa kwambiri. | Kutopa kumayamba m'malo opsinjika kwambiri (zolumikizira, mapewa) pansi pa katundu wozungulira. | Kuchepetsa kuvala konse; cholinga chake ndi kuchepetsa kusokonekera kwa martensite ndi kutalika. |
3. Zinthu Zolimba Kuposa Kapangidwe Koyambira
Kulimba sikungotanthauzidwa ndi mawonekedwe a chigwirizano chokha. Zinthu zingapo zodalirana zimagwira ntchito yofunika kwambiri:
- Sayansi ya Zinthu ndi Zitsulo: Kupita patsogolo kwa zinthu zosakaniza (Cr, Ni, Mn, Mo) ndi chithandizo chabwino cha kutentha (kuzimitsa ndi kutenthetsa) kungathandize kupirira kuwonongeka ndi 10-25%. Zitsulo zapamwamba monga 23MnNiCrMo54 zimagwiritsidwa ntchito kuti zithetse kusweka bwino komanso kuti zikhale ndi moyo wotopa.
- Kudalirika kwa Cholumikizira: Pa makina olumikizirana athyathyathya, cholumikizira nthawi zambiri chimakhala chofooka kwambiri. Kukonza mawonekedwe a mano olumikizirana kuti azitha kugawa bwino nkhawa ndikofunikira kwambiri pa moyo wonse wa makina.
- Chitetezo ku dzimbiri: Kudzimbiritsa kumathandizira kuti zinthu zisawonongeke komanso kutopa. Zophimba zapamwamba zoteteza, monga zinc-nickel plating, zimatha kukulitsa dzimbiri nthawi zambiri poyerekeza ndi zomaliza zachikhalidwe, zomwe zimapangitsa kuti unyolo ukhale wokhalitsa nthawi yayitali m'malo onyowa.
- Machitidwe Ogwirira Ntchito: Kukanikiza bwino ndikofunikira kwambiri. Kukanikiza pang'ono kumayambitsa kufooka ndi kukwapula, pomwe kukanikiza kwambiri kumathandizira kwambiri kuwonongeka ndi kutopa. Kuyang'anitsitsa pafupipafupi ma sprocket ndikofunikiranso, chifukwa ma sprocket osweka amawononga unyolo uliwonse msanga.
4. Ndondomeko Yosankha: Kugwirizanitsa Unyolo ndi Ntchito
Palibe unyolo "wangwiro" padziko lonse, koma pali unyolo woyenera kwambiri pazochitika zinazake. Kusankha kuyenera kukhala njira yogwirizana pakati pa mgodi ndi wopanga.
- SankhaniMa Chain Ozungulira (DIN 22252)pamene: Chofunika kwambiri ndi kusinthasintha kwakukulu ndi kuyamwa kwa mphamvu m'mikhalidwe yovuta komanso yosagwirizana. Kapangidwe kawo kofanana ndi koyenera kugwiritsidwa ntchito pamene kusalinganika bwino kapena kupotoka kungachitike.
- Sankhani StandardMa Chain Olumikizana ndi Flat Link (DIN 22255)pamene: Pali malire a kutalika kwa conveyor, ndipo mawonekedwe apansi a pan amafunika kuti awonjezere mphamvu. Ndi njira yolumikizira mwachindunji makina ozungulira opanda kusintha kwakukulu kwa mzere wa pan.
- Sankhani Ma Chain Apamwamba a "Ultra-Flat" kapena "Solid Profile" pamene: Cholinga cha ntchito ndikuwonjezera nthawi yogwirira ntchito ndikuchepetsa nthawi yogwira ntchito mu ntchito zamphamvu kwambiri komanso zolemera kwambiri. Ma geometry awo opangidwa bwino cholinga chawo ndi kuthana mwachindunji ndi zomwe zimayambitsa kuwonongeka ndi kulephera kwa unyolo.
5. Mapeto
Kusintha kuchokera ku kapangidwe ka round link kupita ku mapangidwe apamwamba a flat-link kukuwonetsa kusintha kuchoka ku kulimba kwa generalized kupita ku magwiridwe antchito abwino kwambiri. Ngakhale kuti round links zimapereka kusinthasintha kwamphamvu, ultra-flat chains ndi ultra-flat chains zimapereka mayankho opangidwa mwaluso kuti pakhale mphamvu yowonjezera komanso moyo wautali. Chisankho cholimba kwambiri ndi chisankho cha dongosolo chomwe chimaganizira za geometry, khalidwe la zinthu, kapangidwe ka zolumikizira, zomaliza zoteteza, komanso—mozama—kukonza koyenera kwa ntchito. Pamapeto pake, kuyika ndalama mu unyolo womwe "ukugwirizana bwino ndi mikhalidwe inayake" komanso wothandizidwa ndi mgwirizano waukadaulo waluso ndiyo njira yothandiza kwambiri yowonjezerera nthawi yogwira ntchito komanso kupanga bwino kwa conveyor ya longwall.
