Lub tuam txhab lub limestone crushing thiab conveying system txais mobile crushing chaw nres tsheb, uas yog siv cov hlau structural thav duab los ntawm limestone silo rau crusher foundation, thiab cov ore bin muaj peev xwm yog hais txog 45t. Nyob rau hauv tus txheej txheem ntawm ntau lawm, cov ore yog poured rau hauv lub bin los ntawm Steyer pob tseg tsheb thiab ncaj qha cuam tshuam rau sab nraum qab ntawm lub tsheb.hnyav hnyav apron feeder, uas ua rau lub deformation ntawm cov nqaj txhawb nqa nyob rau tom qab, steel phaj ntawm kev sib txuas ntawm cov hlua khi hlua khi raug txiav, cov hlua khi hlua khi yog deformed, thiab cov khoom siv tsis tuaj yeem pib nrog cov khoom hnyav. Clearing lub load rau cov cuab yeej pib, tsis tsuas yog cuam tshuam rau cov kev ua haujlwm ib txwm muaj, tab sis kuj siv ntau lub zog thiab cov khoom siv, yog li ntawd, tsis tuaj yeem rov qab qhov teeb meem ntawm kev pib, yuav tsum tau daws raws sijhawm.
2 Ua rau Analysis
Vim hais tias cov limestone silo me me dhau lawm thiab qhov ntev ntawm phab ntsa tom qab ntawm lub silo yog luv dhau, thaum pib ntawm txhua txhua hnub, lub ore roob dawb unloading tsheb yog poured rau hauv lub silo, thiab qhov ncaj qha cuam tshuam yog nyob rau sab nraum qab ntawm lub hnyav hnyav apron feeder. Nyob rau hauv cov txheej txheem tas mus li ntawm 迮, txawm hais tias muaj qee yam khoom siv thiab pob zeb nyob tom qab, nws feem ntau nyias thiab tsis tuaj yeem tsim lub ntuj siab zoo. Thaum cov ore tau nchuav rau hauv lub thawv, lub nraub qaum kuj yuav tsum muaj kev cuam tshuam ntau dua. Yog li ntawd, nyob rau hauv ntev- lub sij hawm ntau lawm, cov saw phaj tsim: me ntsis deformation, cov saw roller yeej tsis dais siab: nyob rau hauv lub cheeb tsam ntawm bearing qhov cuam tshuam, weld ntawm lub I-beam txhawb nqa beam thiab swb rail yog sib cais, tsim ib qho kev sib txawv, thiab lub luag hauj lwm txhawb tsis muaj: lub swb rail txuas steel phaj yog txiav, deformation ntawm tus swb. qhov cuam tshuam cheeb tsam ntawm hnyav hnyav apron feeder. Qhov no mus tas li deformation, nyob rau hauv cov ntaub ntawv ntawm hnyav load, lubhnyav hnyav apron feedertwb tsis txaus pib- muaj peev xwm nce txawm tias ntau dua.
3 Coj Kev Ntsuas
Yuav kom daws tau qhov teeb meem ntawm thav duab deformation thiab hnyav load tsis tuaj yeem pib, peb yuav tsum ntsuas: ua ntej, txo qhov cuam tshuam ntawm ore ntawm lub phaj txwv tshuab; Qhov thib ob yog los txhim kho lawv cov kev tiv thaiv - muaj peev xwm cuam tshuam; Qhov thib peb yog los xyuas qhov pib muaj peev xwm ntawm lub luag haujlwm hnyav apron feeder lub ntsiab lub cev muaj zog, yog tias nws lub peev xwm pib tsis txaus, xaiv lub cev muaj zog uas tuaj yeem ua tau raws li qhov hnyav pib.
3.1 Nws yog tsis yooj yim sua kom muaj peev xwm ntawm lub silo thiab ncua ntev ntawm lub rear phab ntsa ntawm lub silo los ntawm kev txo cov kev cuam tshuam ntawm ore nyob rau hauv lub hnyav luag hauj lwm apron feeder nyob rau hauv lub site tej yam kev mob. Yog tias qhov kev tiv thaiv - cuam tshuam thav duab tau teeb tsa hauv bunker, nws yog qhov tsim nyog los txo qis lub kaum sab xis tom qab lub bunker, kom cov ore cuam tshuam tsis kam thav duab tom qab zawv zawg rau hauv bunker, tom qab suav thiab ntsuas, lub kaum sab xis ntawm phab ntsa tom qab ntawm lub bunker yuav tsum tau txo los ntawm 70℃mus rau 45℃lub bunker, uas tsis tsuas yog txo qhov ntim me me, tab sis kuj txo qis. nqes, nws pom tau tias qhov kev tiv thaiv- cuam tshuam tsis tau.
Txhawm rau kom tsis txhob cuam tshuam rau kev tsim khoom, qhov cuam tshuam ntawm Yeneng Cheng cov ore me me ntawm lub phaj txwv lub tshuab, lub rhiav tau tsim cov kev ntsuas uas cov khoom siv loj ntawm tib neeg lub thawv yog tsawg dua 800 hli, thiab lub thickness ntawm cov khoom txheej nyob rau hauv lub rear ntawm lub hnyav hnyav apron feeder yog guaranteed kom siab tshaj 1 meter, thiab yuav tsum tau nruj me ntsis raws li nyob rau hauv cov txheej txheem ntau lawm.
3.2 Txhim khu kev tiv thaiv
3.2.1 Txhim kho qhov cuam tshuam tsis zoo ntawm cov kab hluav taws xob sab nraub qaum Tshem tawm cov deformed 4 teeb ntawm 8 I- kab teeb ntawm cov qauv 20a nyob rau tom qab ntawm cov khoom hnyav apron feeder thiab hloov lawv nrog 15 I- kab teeb ntawm qauv 20a. I-cov qauv steel thiab cov tsis muaj muaj nyob hauv Table 1. Hom 206 I-beam muaj peev xwm ntau dua li hom 20a T-beam. Raws li tib lub zog cuam tshuam, qhov cuam tshuam quab yuam ntawm txhua qhov kuv- hlau yog ib nrab ntawm qhov qub, thiab tus naj npawb ntawm kuv- hlau los tiv thaiv qhov cuam tshuam tau nce li ob npaug. Los ntawm kev hloov thiab nce hom thiab tus naj npawb ntawm I- nqaj txhawb nqa beam, qhov cuam tshuam tsis zoo tau nce ntau dua 3 zaug.
3.2.2 Txhim kho qhov cuam tshuam tsis zoo ntawm lub luag haujlwm hnyav apron feeder rear swb Tshem tawm cov deformed 32a I-rail thiab hloov nrog lub zog 32b I-rail. Saib Table 1 rau qhov kev sib piv ntawm qhov tsis sib xws ntawm I- steel ntawm ob qhov tshwj xeeb. Raws li tau pom los ntawm Table 1, 32b muaj kev cuam tshuam ntau dua li 32a. Thawj qhov kev sib txuas ntawm tus swb yog nyob rau hauv qhov chaw cuam tshuam ntawm sab nraub qaumhnyav hnyav apron feeder, tab sis nyob rau hauv qhov kev hloov pauv no, qhov kev sib txuas tau muab tso rau hauv qhov tsis muaj - qhov cuam tshuam ntawm qhov chaw nyob rau pem hauv ntej ntawm tus swb. Cov pob txha qub ntawm txhua qhov swb rail siv ob lub 420x260 × 10 cov hlau zoo tib yam, hauv qhov kev hloov pauv no, siv ob 420x260x20 30Mn steel daim hlau. M30x80 siab lub zog bolts yog siv los tiv thaiv lub splint. Tom qab fastening lub bolts thiab ceev, cov hluav taws xob solder pob qij txha yog tuag los tiv thaiv xoob nyob rau hauv cov txheej txheem ntau lawm. Los ntawm cov kev ntsuas saum toj no, nws tau txhim kho nws tus kheej lub zog thiab txhim kho nws cov kev cuam tshuam.
