Izizathu kunye nohlalutyo lomatshini lokuphambuka kwebhanti yokuhambisa ibhanti

Ukuhanjiswa kwebhanti sesona sixhobo siphambili senkqubo yokuhambisa, kwaye ukusebenza kwayo okukhuselekileyo kunye nokuzinza kuchaphazela ngokuthe ngqo ukunikezelwa kwezinto eziluhlaza. Ukuphambuka kwebhanti yeyona nto ixhaphake kakhulu i-conveyor yebhanti , kwaye unyango lwalo olufike ngexesha kunye noluchanekileyo luyisiqinisekiso sokusebenza kwayo okukhuselekileyo kunye nokuzinza. Kukho iziganeko ezininzi kunye nezizathu zokuphambuka, kwaye iindlela ezahlukeneyo zokulungelelanisa kufuneka zamkelwe ngokwezinto ezahlukeneyo kunye nezizathu zokuphambuka, ukuze kulungiswe ngokufanelekileyo ingxaki. Eli phepha lisekelwe kwiminyaka emininzi yokusebenza kwintsimi, ngokwembono yomsebenzisi, usebenzisa umgaqo womatshini ukuhlalutya nokucacisa izizathu zokusilela okunjalo kunye neendlela zonyango.

1. Impazamo yokuma phakathi kwendawo yofakelo ye-idlera ephetheyo kunye nomgca ophakathi we-conveyor mkhulu, okubangela ukuba ibhanti liqhube ukutenxa kwicandelo lokuthwala. Xa ibhanti liqhubela phambili, linika i-roller i-four traction force Fq, echithwayo ibe yi-component force Fz eyenza i-roller ijikeleze kunye ne-lateral component force Fc eyenza i-roller axial movement. Ekubeni i-roller elungiswe yi-idler isakhelo ayikwazi ukuhamba nge-axially, ngokuqinisekileyo iya kuvelisa amandla okuphendula i-Fy kwibhanti, eyenza i-blet ihambe kwelinye icala, ibangele ukutenxa.

Emva kokucacisa malunga nemeko yamandla okutenxa ekuthwaleni i-idler emva kokufakwa, akukho nzima ukuqonda izizathu zokutenxa ibhanti, indlela yohlengahlengiso ikwacacile,Indlela yokuqala kukuqhuba imingxunya emide kumacala omabini esethi ye-idler. ukulungelelaniswa .Indlela ethile yeyokuba leliphi icala ibhanti elikhutshiweyo, kwaye icala le-uvila kufuneka liqhubele phambili kwicala lebhanti, okanye elinye icala kufuneka libuyele umva. Ukuba ibhanti libaleka lisiya phezulu, indawo esezantsi yomntu ovilayo kufuneka ihambe iye ekhohlo, ize inyuke iye ekunene.

Indlela yesibini kukufaka i-idlers yokulungelelanisa, i-idler yokulungelelanisa ineentlobo ezahlukeneyo, ezifana nohlobo lwe-shaft ephakathi, uhlobo lwe-link-four, uhlobo lwe-roller ethe nkqo, njl njl. okanye uvelise i-transverse thrust ukwenza ibhanti ngokuzenzekelayo libe centripetal ukufezekisa injongo yokulungelelanisa ukutenxa kwebhanti, kwaye imeko yoxinzelelo iyafana neyomntu ongasebenziyo. Ngokuqhelekileyo, le ndlela isengqiqweni ngakumbi xa ubude bubonke bomhambisi webhanti bufutshane okanye xa umqhubi webhanti esebenza kumacala omabini, kuba ukuhambisa ibhanti elifutshane kunokwenzeka ukuba libaleke kwaye akukho lula ukuhlengahlengisa. Le ndlela kwi-belt belt conveyor ingcono ukuba ingasetyenziswa , kuba ukusetyenziswa kokulungelelanisa i-idler kuya kuba nefuthe elithile kubomi benkonzo yebhanti.

2. I-axis yentloko yokuqhuba i-pulleyor tail returningpulley ayikho i-perpendicular kumgca ophakathi we-conveyor, obangela ukuba ibhanti libaleke kwi-drum yentloko okanye umsila wokubuyisela umsila. Xa i-pulley ijika, ukuxinwa kwebhanti kumacala omabini e-pulley akuhambelani, kwaye amandla okutsala i-Fq afunyenwe ecaleni kobubanzi abuhambisani, nto leyo iba yinto ekhulayo okanye eyanciphayo, eya kwenza ibhanti lifake amandla ahambayo. I-Fy kwicala elihlayo, okubangela ukuba ibhanti libaleke ukusuka kwicala elivulekileyo, oko kukuthi, okubizwa ngokuba "i-running loose kodwa ingasebenzi ngokuqinileyo".

Indlela yokulungelelanisa ngolu hlobo lulandelayo: kwi-pulley yentloko, ukuba ibhanti libaleka ukuya kwicala lasekunene lepuli, ibhloko yomqamelo ekunene kufuneka iqhubele phambili.Ukuba ibhanti libaleka ukuya kwicala lasekhohlo le-roller. kufuneka iqhubele phambili, kwaye ibloko yomqamelo ehambelanayo ekhohlo nayo inokushenxiswa ngasemva okanye ibhloko yomqamelo wasekunene ibuyiselwe umva. Indlela yokulungelelanisa i-pulley yomsila ichasene ngqo ne-head pulley. Emva kohlengahlengiso oluphindaphindiweyo de ibhande lilungelelaniswe kwindawo efanelekileyo. Kungcono ukufaka i-idler ngokuchanekileyo ngaphambi kokulungelelanisa i-drive okanye i-pulley yokubuya

Okwesithathu, ukunyanzeliswa kokungahambi kakuhle kwendawo yangaphandle ye-pulley, izinto zokubambelela okanye ukugqoka okungafaniyo kubangela ukuba ububanzi buhluke, kwaye ibhanti iya kubaleka ukuya kwicala kunye nobubanzi obukhulu. Leyo yinto ebizwa ngokuba "baleka umkhulu ungabaleki kancinci". Isimo salo samandla: i-tractive force Fq yebhanti yenza i-force yecandelo elihambayo i-Fy ngokubhekiselele kwicala elikhulu lobubanzi, kwisenzo samandla ecandelo le-Fy, ibhanti liya kuvelisa ukuphambuka. Kule meko, isisombululo kukucoca izinto ezincangathi kumphezulu wegubu, indawo ebambekayo kunye ne-mismachining tolrence kunye nokunxiba okungalinganiyo kufuneka kuthathelwe indawo kwaye kuphinde kucutshungulwe ukulahlwa kwerabha.

Okwesine, indawo yokudlulisa kwindawo yokulahla izinto ayiqondile ukuba ibangele ukuphambuka kwebhanti. indawo yokudluliselwa kwemathiriyeli kwindawo yokulahla imathiriyeli ekutenxeni kwebhanti kunempembelelo enkulu kakhulu, ngakumbi uqikelelo lwabahambisi ababini kumhlaba othe tye iye nkqo, impembelelo iya kuba nkulu kakhulu. Ngokuqhelekileyo ukuphakama okuhambelanayo kwamabhanti amabini ngasentla nangaphantsi kwindawo yokudlulisa kufuneka kuthathelwe ingqalelo. Okukhona kusezantsi ukuphakama kwesalamane, kokukhona icandelo lesantya esithe tyaba lesixhobo, kokukhona impembelelo esecaleni kweFc kwibhanti esezantsi, kwaye izinto nazo kunzima ukuzibeka embindini. Izinto eziphathekayo kwinqanaba lomnqamlezo webhanti lichithwa, kwaye inxalenye ethe tye yempembelelo yempembelelo yeFc Fy ekugqibeleni ibangela ukuba ibhanti libaleke. Ukuba izinto eziphathekayo ziya ngasekunene, ibhanti iya ngakwesobunxele, kwaye ngokufanayo.

Ukuphambuka kule meko, ukuphakama okuhambelanayo kwabahambisi ababini kufuneka kwandiswe kangangoko kunokwenzeka ngexesha lenkqubo yoyilo. Ifom kunye nobukhulu beefunnels eziphezulu kunye nezantsi kunye ne-chutes yesikhokelo sokuhambisa amabhanti kunye nezithintelo zendawo kufuneka ziqwalaselwe ngokucophelela. Ngokuqhelekileyo, ububanzi bee-chutes zesikhokelo kufuneka bube malunga nesithathu-esihlanu kububanzi bebhanti. Ukuze unciphise okanye ugweme ukuphambuka kwebhanti, ipleyiti ye-baffle inokongezwa ukuvimba izinto kunye nokutshintsha ulwalathiso kunye nokuma kwezinto.

Isihlanu. Iingxaki zebhanti ngokwayo. ezifana nokusetyenziswa ibhanti ixesha elide, deformation ukuguga, edge banxibe, okanye iziko remade joint ayilunganga emva kokuba ibhanti yonakele, nto leyo eya kwenza ukutsaleleka kumacala omabini ibhanti ahambelani kwaye kukhokelela ukutenxa. Kule meko, ubude bonke bebhanti buya kuhamba kwicala elinye, kwaye ubuninzi obuphumayo bukwindawo engalunganga. Indlela yodwa yokujongana nayo kukuphinda wenze i-rubber edibeneyo kunye neziko elingalunganga, kwaye utshintshe i-deformation yokuguga yebhanti.

Okwesithandathu, isixhobo soxinzelelo se-conveyor asikwazi ukwenza i-nouth tension force kwibhanti. ibhanti ayiphambuki ngaphandle komthwalo okanye inani elincinci lomthwalo, xa umthwalo ukhulu kancinci kuya kubakho ukuphambuka. Isixhobo soxinzelelo sisixhobo esisebenzayo sokuqinisekisa ukuba ibhanti lihlala ligcina amandla okwaneleyo oxinzelelo. Ukuba ukunyanzeliswa kwamandla akwanele, ukuzinza kwebhanti kubi kakhulu, impembelelo enkulu yokuphazamiseka kwangaphandle, kwaye i-phenomenon of slipping iya kwenzeka kwiimeko ezinzulu. Kubathuthi bebhanti besebenzisa izixhobo zoxinzelelo lobunzima, ii-counterweights zinokongezwa ukusombulula ingxaki, kodwa kuninzi akufanele kufakwe, ukuze ungenzi ibhere yebhanti icinezele ngokungeyomfuneko kwaye inciphise ubomi benkonzo yebhanti. Kubaqhubi bebhanti abasebenzisa i-spiral okanye i-hydraulic tension, i-tension stroke inokulungiswa ukwandisa amandla oxinzelelo. Nangona kunjalo, ngamanye amaxesha i-tension stroke ayikwanelanga kwaye ibhanti ikhubazekile ngokusisigxina, ngelo xesha icandelo lebhanti linokunqunyulwa kwaye liphinde liboshwe.

Okwesixhenxe, kwi-conveyor yebhanti kunye noyilo lwe-concave, njenge-radius ye-curvature yecandelo le-concave lincinci kakhulu, ukuba akukho nto kwibhanti xa iqala, ibhanti iya kuvela kwinqanaba le-concave, kwimeko. yemozulu yomoya onamandla nayo iya kuvuthela ibhanti, ngoko ke, kungcono ukongeza ivili lebhanti loxinzelelo kwinqanaba le-concave ye-conveyor yebhanti ukuze ugweme umthombo webhanti okanye uvuthelwe ngumoya.
