Zomwe zimayambitsa ndi kusanthula kwamakina kwa kupatuka kwa lamba wa conveyor lamba

Belt conveyor ndiye chida chachikulu chotumizira, ndipo ntchito yake yotetezeka komanso yokhazikika imakhudza mwachindunji kupezeka kwa zida zopangira. Kupotoka kwa lamba ndilo vuto lalikulu la conveyor lamba , ndipo chithandizo chake cha panthawi yake komanso cholondola ndicho chitsimikizo cha ntchito yake yotetezeka komanso yokhazikika. Pali zochitika zambiri ndi zomwe zimayambitsa kupatuka, ndipo njira zosiyanasiyana zosinthira ziyenera kutengedwa molingana ndi zochitika zosiyanasiyana komanso zomwe zimayambitsa kupatuka, kuti athetse vutoli. Pepalali likuchokera pazaka zambiri zogwirira ntchito m'munda, kuchokera kwa wogwiritsa ntchito, pogwiritsa ntchito mfundo zamakanika kusanthula ndi kufotokoza zomwe zimayambitsa kulephera kotereku ndi njira zothandizira.

1. Cholakwika cha verticality pakati pa malo oyika a idlerandi mzere wapakati wa conveyor ndi waukulu, zomwe zimapangitsa kuti lamba ayambe kupatuka pa gawo lonyamulira. Lamba likamapita patsogolo, limapatsa wodzigudubuza kutsogolo kwa mphamvu Fq, yomwe imawonongeka kukhala gawo la mphamvu Fz yomwe imapangitsa kuti wodzigudubuza azitha kuzungulira ndi chigawo chotsatira cha mphamvu Fc chomwe chimapangitsa kuyenda kwa axial. Popeza chodzigudubuza chokhazikitsidwa ndi chimango chopanda kanthu sichingasunthe axially, mosakayikira chidzatulutsa mphamvu Fy ku lamba, zomwe zimapangitsa kuti blet isunthire mbali inayo, zomwe zimapangitsa kuti apatukane.

Pambuyo pofotokoza momveka bwino za mphamvu ya kupatuka kwa kunyamula osagwira ntchito pambuyo pa kukhazikitsa, sikovuta kumvetsetsa zifukwa za kupatuka kwa lamba, njira yosinthira ikuwonekeranso, Njira yoyamba ndikukonza mabowo aatali mbali zonse za idler set. zosintha .Njira yeniyeni ndiyo mbali yomwe lambayo watsekedwa, ndipo mbali ya wosagwira ntchito iyenera kupita kutsogolo kutsogolo kwa lamba, kapena mbali inayo ibwerere mmbuyo . Ngati lamba akuthamangira kumtunda, malo apansi a wosagwira ntchito ayenera kusunthira kumanzere, ndipo malo apamwamba a wosagwira ntchito ayenera kusunthira kumanja.

Njira yachiwiri ndikuyika ovina oyenda, oyenda oyenda ali ndi mitundu yosiyanasiyana, monga mtundu wapakatikati, mtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu, wodzigudubuza, etc. kapena kupanga transverse thrust kuti lamba likhale lapakati kuti akwaniritse cholinga chosinthira kupatuka kwa lambayo, ndipo kupsinjika kwake kumakhala kofanana ndi kwa munthu wosagwira ntchito. Kawirikawiri, njirayi ndi yomveka bwino pamene kutalika kwa lamba wonyamulira kuli kochepa kapena pamene chonyamulira lamba chikuyenda mbali zonse ziwiri, chifukwa cholozera lamba chachifupi chimatha kutha ndipo sizovuta kusintha. Njira imeneyi pa conveyor yaitali lamba ndi bwino kuti asagwiritse ntchito , chifukwa ntchito aligning idler adzakhala ndi zotsatira zina pa moyo utumiki lamba.

2. Mzere wa mutu woyendetsa pulleyor mchira returningpulley si perpendicular kwa mzere wapakati wa conveyor, zomwe zimapangitsa lamba kuthamanga pamutu ng'oma kapena mchira reversing ng'oma. Pamene pulley ikusokonekera, kumangika kwa lamba kumbali zonse ziwiri za pulley sikumagwirizana, ndipo mphamvu yokoka ya Fq yomwe imalandira m'lifupi mwake imakhala yosagwirizana, yomwe imakhala yowonjezereka kapena yocheperapo, yomwe imapangitsa lamba kumangiriza mphamvu yosuntha. Fy mu njira yochepetsera, zomwe zimapangitsa lamba kuthawa kumbali yotayirira, ndiko kuti, zomwe zimatchedwa "kuthamanga koma osathamanga".

Njira yosinthira ili motere: kwa pulley yamutu, ngati lamba akuthamangira kumanja kwa pulley, pilo yoyenera iyenera kupita patsogolo. iyenera kupita patsogolo, ndipo chipika chofananira chakumanzere chingathenso kusunthidwa mmbuyo kapena chipilo chakumanja chimasunthidwa mmbuyo. Njira yosinthira pulley ya mchira ndiyosiyana ndendende ndi pulley yamutu. Pambuyo pakusintha mobwerezabwereza mpaka lamba atasinthidwa kukhala malo abwino. Ndi bwino kuyika idler molondola musanasinthe galimoto kapena pulley yobwerera

Chachitatu, kulekerera kolakwika kwa kunja kwa pulley, zomatira kapena kuvala kosagwirizana kumapangitsa kuti m'mimba mwake ikhale yosiyana, ndipo lamba lidzathamangira kumbali ndi mainchesi akuluakulu. Ndiko kutchedwa "kuthamanga kwakukulu osati kuthamanga kochepa". Mkhalidwe wake wa mphamvu: mphamvu yogwira Fq ya lamba imapanga mphamvu yosuntha Fy kumbali yaikulu ya m'mimba mwake, pochita mphamvu ya chigawo Fy, lamba lidzatulutsa kupatuka. Pazimenezi, njira yothetsera vutoli ndikutsuka zinthu zomata pamwamba pa ng'oma, malo otsalira omwe ali ndi vuto losasunthika komanso kuvala kosagwirizana kuyenera kusinthidwa ndikusinthanso mphira.

Chachinayi, malo osinthira pa malo ogwetsera zinthu sizowongoka kuti apangitse kupatuka kwa lamba. malo kutengerapo zinthu pa zinthu akugwetsa udindo pa kupatuka lamba ali ndi zotsatira yaikulu kwambiri, makamaka conveyors awiri kusonyeza pa nthaka yopingasa wakhala ofukula, zotsatira adzakhala lalikulu kwambiri. Kawirikawiri kutalika kwachibale kwa malamba awiri pamwamba ndi pansi pa malo otumizira kuyenera kuganiziridwa. Kutsika kwa kutalika kwachibale, kukulirakulira kwa liwiro lopingasa la zinthuzo, kumapangitsanso kwambiri Fc pa lamba wapansi, komanso zinthuzo zimakhala zovuta kuziyika. Zomwe zili pamtanda wa lamba zimapotozedwa, ndipo gawo lopingasa la mphamvu yamphamvu ya Fc Fy pamapeto pake imapangitsa kuti lambawo athawe. Ngati zakuthupi zikupita kumanja, lamba amapita kumanzere, ndipo mosiyana.

Kwa kupatuka pankhaniyi, kutalika kwachibale kwa ma conveyors awiriwo kuyenera kuonjezeredwa momwe mungathere panthawi yopanga mapangidwe. Mawonekedwe ndi kukula kwa ma fanulo apamwamba ndi apansi ndi ma chute owongolera a malamba okhala ndi malire a malo ayenera kuganiziridwa mosamala. Kawirikawiri, m'lifupi mwa ma chute otsogolera ayenera kukhala pafupifupi atatu ndi asanu a m'lifupi mwa lamba. Pofuna kuchepetsa kapena kupewa kupatuka kwa lamba, mbale ya baffle ikhoza kuwonjezeredwa kuti itseke zinthuzo ndikusintha njira ndi malo azinthu.

Chachisanu. Mavuto a lamba wokha. monga kugwiritsa ntchito lamba kwa nthawi yayitali, kusinthika kwa ukalamba, kuvala m'mphepete, kapena pakati pa mgwirizano wokonzanso sikuwongoka pambuyo pakuwonongeka kwa lamba, zomwe zingapangitse kupsinjika kwa mbali ziwiri za lamba kusagwirizana ndikupangitsa kupatuka. Pankhaniyi, kutalika konse kwa lamba kumathamangira kumbali imodzi, ndipo kuthamangitsidwa kwakukulu kuli pa mgwirizano wolakwika. Njira yokhayo yothanirana nayo ndiyo kupanganso mgwirizano wa mphira ndi malo olakwika, ndikusintha kusintha kwa ukalamba kwa lamba.

Chachisanu ndi chimodzi, kumangika chipangizo cha conveyor sangathe kupanga enouth mavuto mphamvu lamba. lamba sapatuka popanda katundu kapena katundu wochepa , pamene katunduyo ali wamkulu pang'ono padzakhala chodabwitsa chosiyana. Chipangizo chomangika ndi chida chothandizira kuonetsetsa kuti lamba nthawi zonse amakhala ndi mphamvu zokwanira zolimbana. Ngati mphamvu yamphamvu sikwanira, kukhazikika kwa lamba kumakhala kovutirapo kwambiri, kukhudzidwa kwakukulu kwa kusokoneza kwakunja, ndipo chodabwitsa cha kutsetsereka chidzachitika pazovuta zazikulu. Kwa onyamula lamba pogwiritsa ntchito zida zolimbitsa thupi, ma counterweights amatha kuwonjezeredwa kuti athetse vutoli, koma sayenera kuonjezedwa kwambiri, kuti musapangitse lamba kukhala wovuta kwambiri ndikuchepetsa moyo wautumiki wa lamba. Kwa onyamula lamba pogwiritsa ntchito spiral kapena hydraulic tension, kugunda kwamphamvu kumatha kusinthidwa kuti kuwonjezere mphamvu. Komabe, nthawi zina kupwetekedwa mtima kumakhala kosakwanira ndipo lamba amakhala wopunduka kwamuyaya, panthawi yomwe gawo la lamba likhoza kudulidwa ndikumangidwanso.

Chachisanu ndi chiwiri, kwa conveyor lamba ndi mapangidwe a concave , monga utali wopindika wa gawo la concave ndi laling'ono kwambiri, ngati palibe zinthu pa lamba poyambira, lamba lidzatuluka pa gawo la concave, ngati palibe zinthu pa lamba. mphepo yamkuntho yamphamvu idzawomberanso lamba, choncho, ndi bwino kuwonjezera gudumu lamba lamba pa gawo la concave la conveyor lamba kuti mupewe kasupe wa lamba kapena kuwombedwa ndi mphepo.
