B1200 hnyav hnyavthee apron feederua los ntawm peb lub tuam txhab, kev pub mis ceev yog 0.012 ~ 0.035m / s, lub cev muaj zog yog YCT250-4A, thawj reducer NGW92-11, lwm yam reducer WHX360, uas yog siv rau limestone conveying. Lub tshuab tuaj yeem thauj cov khoom siv ntau tshaj plaws ntawm qhov loj ntawm 450mm, limestone los ntawm qhov chaw cia hauv ob peb metres mus rau hauv qab hauv pem teb, kom cov khoom siv hauv qab mus sij hawm ntev cuam tshuam cov load thiab cov ntaub ntawv nyob rau hauv qhov chaw nres nkoj cia nyob rau hauv tsub zuj zuj ntawm cov phaj hauv qab kom dais static load. Seem saib ntawm qhov tau txais seem ntawm qhov kawg ntawm Coal Apron Feeder. Txhawm rau tiv thaiv kom tsis txhob deformation ntawm lub phaj hauv qab, tsib qhov hnyav steel rails tau sib npaug sib npaug hauv qab phaj, thiab tus neeg pw tsaug zog yog pab hauv qab txoj kev tsheb ciav hlau.
Txhua lub phaj hauv paus yog drilled nrog 4-21 qhov thiab tsau rau ob sab ntawm M900 saw phaj (ISO1977/1-1976 tus qauv) nrog plaub M20 bolts. Hla-section daim duab ntawm lub phaj hauv qab. Lub phaj hauv qab yog tsim los ntawm kub nias ntawm 16MnRe18mm tuab steel phaj. Txhawm rau tiv thaiv kom tsis txhob muaj qhov sib txawv ntawm cov khoom noj uas nyob ib sab hauv qab daim hlau, square steel strips yog welded rau hauv qab phaj. Ob sab ntawm cov khoom tuav Q235, 10mm tuab, vertically welded rau hauv qab phaj. Lub taub hau ntawm chav tsev muaj ob tsav tsheb sprockets, tus Tsov tus tw muaj ob tensioning sprockets, ntsia hlau tensioning ntaus ntawv.
Qhov tsawg kawg nkaus clearance ntawm lub phaj hauv qab thiab cov thav duab ruaj yuav tsum tau lav nyob rau hauv kev tsim, tsim, installation thiab debugging. Clearance nruab nrab ntawm cov phaj tiv thaiv thiab guarded ntug.
1. Clearance nruab nrab ntawm tus neeg zov ntug thiab kev txhawb nqa.
2. Qhov sib txawv ntawm qhov siab ntawm tus neeg saib xyuas thiab kev txhawb nqa ntawm lub phaj tiv thaiv
3 tus pin ncej kawg channeling momentum thiab clearance nrog kem
4. Yog tias qhov kev tshem tawm yam tsawg kawg nkaus ntawm kev ua haujlwm tsis tuaj yeem lav tau, kev cuam tshuam tsis zoo yuav ua rau muaj kev puas tsuaj loj.
2) Kev tsim khoom zoo ntawm ob qho tib si sib npaug sib npaug traction phaj chains hauv chav tsev tsis zoo. Chain phaj pitch manufacturing precision yog qhov tsis zoo, ua rau muaj kev ua yuam kev ntau dhau
Tsis zoo, ob lub traction chains khiav tawm ntawm sync, ua rau dislocation, nce traction tsis kam thaum ua haujlwm. Thib ob, tsav sprocket hniav zoo li thiab saw zawj txoj hauj lwm ua dislocation, ua rau ob lub saw kis tau tus mob tsis synchronous, qhov loj ntawm tensile kev nyuaj siab, ib qho ntawm cov kev khiav hauj lwm tshaj lub phaj saw bearing load thiab cov saw tawg. Txhawm rau tshem tawm cov kev cuam tshuam ntawm qhov kev tsim khoom no yuam kev, ib qho ntawm cov tensioning sprocket tsis yog muab nrog ib txoj hauv kev tseem ceeb, tsim cov qauv ntawm lub nkoj caij nkoj, tab sis qhov yuam kev loj dhau yuav ua rau muaj teeb meem yav tom ntej.
3) Lub phaj hauv qab swb ntawm tsib txoj hlua hlau. Vim tias cov kev sib raug zoo tau cuam tshuam rau lub sijhawm ntev thiab tsim cov yas deformation, tsib txoj hlua hlau tsis tuaj yeem lav.
Txoj kev tsheb ciav hlau nyob hauv tib lub dav hlau los txhawb lub phaj hauv qab, thiab qhov chaw txhawb nqa tau txo qis, uas ua rau cov phaj hauv qab deformation thiab ua rau cov zawv zawg tsis kam ntawm txoj kev tsheb nqaj hlau.
4) Coal apron feeder hauv qab phaj yog tsim los ntawm kub nias, thiab qhov deb ntawm arc S yog me me. Thaum lub phaj hauv qab tig ntawm lub taub hau thiab tus Tsov tus tw sprocket, ob lub phaj hauv qab uas nyob ib sab yuav sib tsoo ntawm lub kaum sab xis ntawm lub kaum sab xis ntawm lub qhov rooj, thiab cov saw phaj pawg yuav khiav los ntawm kev quab yuam, ua rau cov saw hlau dhia ntawm cov hniav zoo nkauj ntawm lub sprocket thiab ua kom cov traction tsis kam.
2.2 Roller ncej tes tsho ntawm lub saw phaj tawg
Cov qauv yooj yim ntawm M900 saw cov menyuam, vim yog cov hmoov hlau metallurgy roj-cov kabmob lub tes tsho kom tiv taus cov kev cuam tshuam saum toj no ntev,
Nws lub peev xwm thauj khoom tsis zoo, yooj yim tawg.
2.3 Traction fais fab tsis ua hauj lwm tshwm sim los ntawm kev sib txuam tsis raug thiab xaiv cov reducer
Qhov sib txuam ntawm reducer yog thawj zaug txiav txim siab los ntawm txoj kev sib kis, cov txheej txheem ib txwm muaj: nyob rau hauv kev ua haujlwm ceev ceev ntawm cov khoom hnyav, kev cuam tshuam ntawm qhov chaw ua haujlwm.
Hauv qab, lub tshuab dav dav - reducer - qhib iav - tsav sprocket qauv. Qhov kev tsim qauv no npog thaj tsam loj thiab muaj kev ntseeg siab hauv kev siv, tab sis yuav tsum tau tsim cov khoom siv loj modulus. Vim hais tias nws yog ib qho nyuaj rau tsim loj module iav nyob rau hauv lub Hoobkas thiab thiaj li yuav txo tau qhov chaw ntawm lub tsev, lub cev muaj zog - I planetary iav reducer - II cab iav reducer los ntawm cov coupling tsav sprocket. Qhov tawg ntawm worm iav crown tshwm sim tom qab siv tsawg tshaj li ib xyoos. Los ntawm kev tsim cov kev tsom xam kis tau tus mob, kev coj tus kheej cuam tshuam kev thauj khoom siv tshuab, nrog qhib iav yog qhov ua tau zoo dua thiab txhim khu kev qha. Qee qhov kev siv tsis txaus ntseeg thiab kev tsim khoom yuav tsum tau xav txog hauv kev tsim lub zog sib piv cov txheej txheem, yog li kev faib hluav taws xob yuav tsum tawm hauv qee chav.
3. Kev txhim kho kev ntsuas thiab cov teebmeem
1) Tshem tawm cov thawj khi thiab kev tsheb nqaj hlau nyob rau hauv qhov tau txais ntawm cov thee apron feeder, txais peb kab ntawm cov cuab yeej txhawb nqa lub log los txhawb lub phaj hauv qab, thiab hloov cov kev txhawb nqa zawv zawg rau kev txhawb nqa yob
Qhov kev txhawb nqa nruj no tuaj yeem txo qhov deformation thiab khiav tsis kam ntawm cov phaj hauv qab, uas yog txhim khu kev qha hauv kev ua haujlwm thiab yooj yim hauv kev saib xyuas, raws li qhia hauv daim duab 5.
Seem saib ntawm kev txhim kho kev xa khoom
1. Txhawb lub log; 2. Txhawb nqa ncej; 3. Kev them nyiaj yug ntaus ntawv bracket; 4. Cov phaj hauv qab Ntxiv rau, vim tias cov phaj hauv qab yog ua los ntawm 16MnRe steel phaj, nws yuav tsum tau kub - nias los ntawm 1000t roj xovxwm, thiab cov phaj hauv qab muaj qhov nruj heev.
Yog li nws muaj peev xwm txais kev txhawb nqa nruj.
2) Cov hmoov hlau metallurgy roj- bearing bushing ntawm M900 saw roller yog hloov nrog 2210 ib kab centripetal luv cylindrical roller bearing, raws li qhia hauv daim duab 6.
Nyob rau hauv cov xwm txheej ntawm ib txwm lubrication, kev ua haujlwm tsis zoo yog me me, thiab lub load-cov kabmob muaj kev nyab xeeb thiab txhim khu kev qha.
1. Pin ncej rau hauv roj channel; 2. Txhawb lub log; 3. Cov kabmob; 4. Sab nrauv saw phaj
3) Tensioning tail log caij nplooj ntoos hlav tensioning ntaus ntawv muaj 4 channel steel slideway, yooj yim rau deformation thiab dabtsi yog khoov. Nrog Q235, δ=14mm steel
Cov phaj yog ua los ntawm 45℃reinforcement daim hlau thiab welded rau ntawm daim hlau groove thiab txhua kab txhawm rau ua kom qhov tawv nqaij ntawm qhov kev ntxhov siab ntawm lub tailframe, raws li qhia hauv daim duab 3.
4) Tus qauv tsim ntawm lub phaj hauv qab S=5mm, nce S mus rau 10mm, daws ob daim hlau hauv qab uas nyob ib sab hauv lub taub hau thiab tus Tsov tus tw sprocket
Kev sib tsoo ntawm lub voj voog ntawm kev sib hloov.
5)Coal apron feedertail txais seem kem thiab nqaj thawj qauv, vuam qauv ntev -lub sij hawm cuam tshuam kev co yog yooj yim rau vuam. Daim duab tam sim no
7b bull ceg strut qauv, cuam tshuam tsis kam, siv ntau txhim khu kev qha.
6) Ob lub -theem reducer txais tshwj xeeb reducer, uas tsis muaj teeb meem nyob rau hauv ob xyoos dhau los thiab ntseeg tau siv.
