Kev nyab xeeb kev teeb tsa ntawmAerial ua haujlwm platform
Txhawm rau kom ntseeg tau tias qhov kev nyab xeeb ntawm lub cuab tam, muaj ntau cov khoom siv kev nyab xeeb rau kev nqa cov platform. Niaj hnub no peb yuav tham txog cov khoom siv tiv thaiv kev nyab xeeb thiab kev nyab xeeb hloov chaw:
1. Cov khoom siv caij nplooj zeeg kev nyab xeeb
Cov cuab yeej tawm tsam kev nyab xeeb yog ib qho tseem ceeb ntawm lub cuab tam, thiab nws yog ib qho tsim nyog los tshem tawm qhov tshwm sim ntawm tawb cov xwm txheej poob thiab ua kom cov neeg muaj kev nyab xeeb. Yog li no, kev xeem lub Hoobkas ntawm kev tiv thaiv kev nyab xeeb cov cuab yeej nruj heev. Ua ntej tawm hauv lub hoobkas, chav kuaj xyuas kev cai lij choj yuav ntsuas lub zog, ntsuas qhov tseem ceeb ceev, thiab ntsuas lub caij nplooj ntoo hlav compression. Txhua koog yog nrog cov ntawv ceeb toom xeem thiab sib sau ua ke ntawm of the elevator. Qhov kev kuaj mob poob qis nyob rau hauv kev ntsuas ntsuas yog nqa tawm, thiab lub chaw tsim kho yuav tsum tau poob txhua peb lub hlis. Cov khoom siv tawm tsam kev nyab xeeb ntawm kev nqa lub platform uas tau xa mus rau hauv chav kuaj xyuas kev nyab xeeb) yuav tsum tau xa mus rau lub chaw kuaj xyuas kev nyab xeeb rau kev kuaj thiab kuaj, thiab tom qab ntawv ib xyoos ib zaug. Kom deb li deb Vim li cas ho tsis ntsuam xyuas thiab xa mus soj ntsuam tsis tu ncua raws li lub system? Nws yog qhov zoo yog tias tus neeg siv khoom blindly xav tias nws tsis yog qhov phem. Qhov tseeb, qhov zoo ntawm kev tiv thaiv kev nyab xeeb kev nyab xeeb tsuas yog txiav txim los ntawm kev sim thiab tshuaj ntsuam. Nws yog tsis yooj yim sua kom txiav txim siab seb nws yog qhov zoo lossis tsis zoo hauv kev ua haujlwm txhua hnub. Rau cov neeg tawm tsam poob kev nyab xeeb uas tau ua haujlwm rau ncua sijhawm, nws pom zoo kom xa mus kuaj ua ntej thiab tsis tu ncua. Kev sim yog qhov zoo, thiab tsuas yog paub txog yuav ua li cas peb tuaj yeem tiv thaiv kev sib raug zoo ua ntej lawv tshwm sim. (Nrhiav kom pom cov khoom siv tiv thaiv kev nyab xeeb tuaj yeem xa mus rau: Changhai Acadection Center, Shanghai Academency ntawm kev tsim kho kev kawm, Shanghai Jiaotong University, thiab lwm yam)
2. Kev ruaj ntseg hloov
Cov kev nyab xeeb ntawm kev nqa tau txhua yam tsim los ntawm kev tsim kho, suav nrog txoj kev hloov pauv, tsis pub dhau lub qhov rooj kev hloov pauv, tsis pub dhau lub qhov rooj kev hloov pauv, cov kab ke ntawm lub qhov rooj kev hloov pauv ntawm kev tiv thaiv thiab cog cov khoom siv zais cia. Piv txwv li: Lub pob tawb dai yuav tsum tau thauj khoom nrog cov khoom ntev, thiab lub kaw dai teeb tsis haum rau sab hauv thiab xav tau qhov rooj txwv lossis sab saum toj qhov rooj txwv tsis pub tso tseg. Nyob rau hauv cov ntaub ntawv ntawm kev muaj kev nyab xeeb lossis tsis tiav cov chaw nyob sab saud, tseem nqa cov neeg thiab thauj cov haujlwm tsis raug cai yog qhov cuav xwm rau tib neeg lub neej. Txhawm rau kom tsis txhob zais cov phom sij ntawm cov xwm txheej, nws cia siab tias cov thawj coj ntawm kev saib xyuas kev nyab xeeb thiab kev ntseeg tau ntawm ntau yam kev nyab xeeb kom tiv thaiv kev sib raug zoo.
Txhawm rau kom ntseeg tau tias qhov kev nyab xeeb ntawm lub cuab tam, muaj ntau cov khoom siv kev nyab xeeb rau kev nqa cov platform. Niaj hnub no peb yuav tham txog kev hloov pauv ntawm lub zog thiab racks, tus nqi ib ntus thiab tsis yog:
3. Hnav thiab hloov ntawm lub zog thiab racks
Thaum kev tsim kho hauv chaw tsim kho, lub chaw ua haujlwm ua haujlwm hnyav, thiab cement, tshuaj khib, thiab hmoov av tsis tuaj yeem tshem tawm. Lub zog thiab racks tau sib tsoo sib tsoo, thiab cov hniav tseem siv tom qab lawv tau ntse dua. Qhov no yuav tsum tau ua tiag tiag. Raws li peb txhua tus paub, cov hniav profile yuav tsum zoo li lub puam canilevever. Thaum hnav rau qee qhov loj me, lub iav (lossis khib) yuav tsum tau hloov. Koj yuav tsum tsis txhob siv nws li cas thiab hloov nws nrog ib qho tshiab? Nws tuaj yeem ntsuas nrog 25-50mm hom micrometer. Thaum qhov ntev ntawm cov tsos ib txwm hnav los ntawm 37.1mm mus rau tsawg dua 35.1mm (2 cov hniav), lub iav tshiab yuav tsum tau hloov. Thaum cov khib yog hnav tawm, ntsuas los ntawm cov hniav thickness caliper. Thaum lub Chord qhov siab yog 8 hli, cov hniav tuab yog hnav los ntawm 12,56mm rau tsawg dua 10.6mm. Yuav tsum tau hloov khib. Txawm li cas los xij, muaj ntau ntau "cov hniav hniav" gears ntawm lub chaw tsim kho. Lub platform tseem nyob hauv kev pabcuam dhau sijhawm. Vim kev nyab xeeb, cov chaw tshiab yuav tsum tau hloov.
4. Tus nqi thauj mus ib ntus
Lub tshuab hluav taws xob ntawm cov chaw tsim kho yog nquag ua haujlwm thiab cov teeb meem ntawm kev ua haujlwm ib ntus Lub cuab yeej siv ntawm qee qhov chaw tsim khoom tau raug xauj los ntawm cov tuam txhab qiv khoom thiab ib txwm xav ua kom muaj kev siv tag nrho ntawm nws. Txawm li cas los xij, tus nqi thauj mus ib ntus ntawm lub cev muaj zog (FC = 40% lossis 25%) yog tsis quav ntsej. Vim li cas lub cev muaj zog tsim cua sov? Qee tus tseem siv txawm tias muaj qhov tsis muaj ntxhiab tsw phem, uas yog kev ua haujlwm tsis zoo. Yog hais tias of the elevator kis tau zoo los yog khiav tsis zoo lossis khiav tawm loj heev, dhau lawm, nws yog lub laub me me. Yog li, txhua tus tsav tsheb hauv lub chaw tsim chaw yuav tsum to taub cov tswv yim ntawm lub voj voog thiab ua raws li kev cai tshawb fawb. Qhov no zoo ntawm lub cev muaj zog nws tus kheej yog tsim los rau kev ua haujlwm sib quas ntus.
5. Tsis
Kab xeem ntawm kev tiv thaiv rau kev nyab xeeb ntawm lub lifting platform ntawm lub ntas, ua ntej, tuaj yeem tiv thaiv kev cuam tshuam ntawm of the elevator lub zog, thiab ua si tsis muaj zog. Thiab tam sim no ntau qhov chaw tsim kev tsim kho, txawm hais tias qee tus teeb tsa, tab sis tsis txaus ntseeg, tsis muaj qhov tsis txaus ntseeg, tsis muaj qhov tsis txaus ntseeg, tsis muaj qhov tsis txaus ntseeg, tsis muaj qhov tsis txaus ntseeg, tsis muaj qhov tsis txaus ntseeg, tsis muaj kev soj ntsuam cov kab kawg ntawm kev tiv thaiv no.
