Kev ruaj ntseg ntaus ntawv raulifting platform

Txhawm rau kom ntseeg tau tias muaj kev nyab xeeb ntawm lub lifting platform, muaj ntau yam kev nyab xeeb rau covlifting platform. Niaj hnub no peb yuav tham txog cov khoom siv tiv thaiv lub caij nplooj zeeg thiab kev nyab xeeb hloov pauv:

   1. Cov khoom siv tiv thaiv lub caij nplooj zeeg

Cov cuab yeej tiv thaiv kev poob qis yog qhov tseem ceeb ntawm cov khoom sivlifting platform, thiab nws yog ib qho tsim nyog yuav tsum tau tso siab rau nws kom tshem tawm qhov tshwm sim ntawm lub tawb poob thiab ua kom muaj kev nyab xeeb ntawm cov neeg nyob. Yog li ntawd, lub Hoobkas kuaj ntawm cov khoom siv tiv thaiv kev poob yog nruj heev. Ua ntej yuav tawm hauv lub hoobkas, chav kuaj xyuas kev cai lij choj yuav ntsuas lub torque, ntsuas qhov ceev ceev, thiab ntsuas lub caij nplooj ntoos hlav compression. Txhua chav tsev yog nrog los ntawm ib daim ntawv ntsuam xyuas thiab sib sau ua ke ntawm lub elevator. Kev ntsuas kev poob qis hauv qhov ntsuas ntsuas tau ua tiav, thiab lub tshuab nqa nqa hauv kev siv ntawm qhov chaw tsim kho yuav tsum tau muab tshem tawm txhua peb lub hlis. Cov cuab yeej tiv thaiv kev poob qis ntawm kev nqa lub platform uas tau muab xa tuaj rau ob xyoos (hnub xa khoom ntawm cov khoom siv tiv thaiv kev poob qis) kuj yuav tsum raug xa mus rau chav kuaj xyuas kev cai lij choj rau kev tshuaj xyuas thiab kev sim, thiab tom qab ntawd kuaj ib xyoos ib zaug. . Txog tam sim no, tsawg tus neeg tau xa mus rau kev tshuaj xyuas, thiab qee qhov chaw tsim kho tsis tau ua qhov kev sim poob txhua peb lub hlis, xav tias lawv cov khoom siv tiv thaiv lub caij nplooj zeeg tsis zoo, tab sis thaum muaj xwm txheej tshwm sim, lawv khuv xim nws. Vim li cas ho tsis kuaj thiab xa mus kuaj xyuas tsis tu ncua raws li qhov system? Nws yog qhov zoo yog tias cov neeg siv khoom dig muag xav tias nws tsis yog qhov phem. Qhov tseeb, qhov zoo ntawm cov cuab yeej tiv thaiv kev poob qis tuaj yeem raug txiav txim los ntawm kev sim thiab tshuaj xyuas. Nws tsis tuaj yeem txiav txim siab seb nws yog qhov zoo lossis qhov tsis zoo hauv kev ua haujlwm txhua hnub. Rau cov cuab yeej tiv thaiv kev nyab xeeb uas tau ua haujlwm rau lub sijhawm ntev, nws raug nquahu kom xa mus rau kev tshuaj xyuas thiab kev sim tsis tu ncua yog qhov zoo, thiab tsuas yog los ntawm kev paub yuav ua li cas thiaj tuaj yeem tiv thaiv kev raug mob hnyav ua ntej lawv tshwm sim. (Kev kuaj xyuas cov khoom siv tiv thaiv lub caij nplooj zeeg tuaj yeem raug xa mus rau: Changsha National Siv Tshuab Kev Tshawb Fawb Kev Ua Haujlwm Zoo, Shanghai Academy ntawm Kev Tsim Kho Kev Tshawb Fawb, Shanghai Jiaotong University, thiab lwm yam.)

   2. Kev nyab xeeb hloov

Kev nyab xeeb hloov ntawm lub nqa yog txhua yam tsim los raws li kev xav tau kev nyab xeeb, suav nrog lub laj kab qhov rooj txwv, lub tawb qhov rooj txwv, lub qhov rooj sab saum toj txwv, txwv hloov, sab sauv thiab qis qis hloov, counterweight los tiv thaiv txoj hlua tiv thaiv kev hloov, thiab lwm yam hauv qee qhov chaw tsim kho , txhawm rau kom txuag tau qhov teeb meem, qee qhov kev txwv kev hloov pauv tau raug tshem tawm manually thiab luv luv lossis puas thiab tsis kho raws sijhawm, uas yog sib npaug rau kev tshem tawm cov kab kev nyab xeeb ntawm kev tiv thaiv thiab cog cov xwm txheej zais. Piv txwv: Lub tawb dai yuav tsum tau ntim cov khoom ntev, thiab lub tawb dai tsis tuaj yeem haum rau sab hauv thiab yuav tsum tau ncua tawm ntawm lub tawb dai, thiab lub qhov rooj txwv lossis lub qhov rooj sab saum toj yog muab tso tseg. Nyob rau hauv cov ntaub ntawv ntawm qhov chaw tsis zoo los yog tsis tiav kev nyab xeeb uas tau hais los saum toj no, tseem nqa tib neeg thiab thauj khoom zoo li kev ua haujlwm tsis raug cai no yog qhov tso dag rau tib neeg lub neej. Txhawm rau kom tsis txhob muaj kev phom sij zais cia ntawm kev sib tsoo, nws cia siab tias cov thawj coj ntawm chav tsev yuav ntxiv dag zog rau kev tswj hwm, nruj me ntsis kom muaj kev saib xyuas ntawm lub platform nqa thiab cov neeg ua haujlwm kom tsis tu ncua xyuas kev nyab xeeb thiab kev ntseeg siab ntawm ntau yam kev nyab xeeb hloov los tiv thaiv kev sib tsoo.

Txhawm rau kom ntseeg tau tias muaj kev nyab xeeb ntawm lub lifting platform, muaj ntau yam kev nyab xeeb rau covlifting platform. Niaj hnub no peb yuav tham txog kev hloov cov iav thiab racks, tus nqi thauj khoom ib ntus thiab qhov tsis sib xws:

   3. Hnav thiab hloov cov iav thiab racks

Thaum lub sij hawm tsim kho ntawm qhov chaw tsim kho, qhov chaw ua haujlwm hnyav, thiab cov cement, mortar, thiab plua plav tsis tuaj yeem raug tshem tawm. Cov iav thiab racks sib tsoo ib leeg, thiab cov hniav tseem siv tau tom qab lawv sharpened. Qhov no yuav tsum tau ua tiag tiag. Raws li peb txhua tus paub, tus hniav profile yuav tsum zoo li lub cantilever beam. Thaum hnav rau ib qho me me, lub iav (los yog khib) yuav tsum tau hloov. Yuav ua li cas kuv yuav tsum tsis txhob siv nws thiab hloov nws nrog ib tug tshiab? Nws tuaj yeem ntsuas nrog 25-50mm ib txwm micrometer. Thaum qhov ntev ntawm cov khoom siv ib txwm siv los ntawm 37.1mm mus rau tsawg dua 35.1mm (2 hniav), yuav tsum tau hloov cov iav tshiab. Thaum lub khib yog hnav, ntsuas los ntawm cov hniav thickness caliper. Thaum lub chord qhov siab yog 8 hli, cov hniav tuab yog hnav los ntawm 12.56mm mus rau tsawg dua 10.6mm. Lub khib yuav tsum tau hloov. Txawm li cas los xij, muaj ntau "cov hniav qub" iav ntawm qhov chaw tsim kho. Lub platform tseem nyob rau hauv kev pabcuam dhau sijhawm. Rau kev nyab xeeb, cov khoom tshiab yuav tsum tau hloov.

   4. Kev thauj khoom ib ntus

Lub elevator ntawm qhov chaw tsim kho tau nquag ua haujlwm thiab kev siv tus nqi siab, tab sis qhov teeb meem ntawm kev ua haujlwm tsis sib xws ntawm lub cev muaj zog yuav tsum tau txiav txim siab, uas yog, qhov teeb meem ntawm kev thauj khoom ib ntus (qee zaum hu ua lub sijhawm thauj khoom) , uas txhais tau tias yog FC = lub sijhawm ua haujlwm lub sijhawm / lub sijhawm thauj khoom × 100%, qhov twg lub sijhawm ua haujlwm lub sijhawm yog lub sijhawm thauj khoom thiab lub sijhawm poob. Lub lifting platform ntawm qee qhov chaw tsim kho yog xauj los ntawm lub tuam txhab leasing thiab ib txwm xav siv nws tag nrho. Txawm li cas los xij, tus nqi thauj khoom ib ntus ntawm lub cev muaj zog (FC = 40% lossis 25%) yog tsis quav ntsej kiag li. Vim li cas lub cav tsis ua kom sov? Qee qhov tseem siv tau txawm tias muaj ntxhiab tsw, uas ua haujlwm txawv txav. Yog hais tias lub elevator kis tau tus mob tsis zoo lubricated los yog khiav tsis kam yog loj heev, overloaded, los yog nquag pib, nws yog ib tug me me lub laub nees. Yog li ntawd, txhua tus neeg tsav tsheb ntawm qhov chaw tsim kho yuav tsum nkag siab lub tswv yim ntawm lub luag haujlwm lub voj voog thiab ua raws li kev cai lij choj. Hom lub cev muaj zog nws tus kheej yog tsim los rau kev ua haujlwm tsis sib xws.

5. Tsis pub

Txoj kab kawg ntawm kev tiv thaiv rau kev nyab xeeb ntawm kev nqa lub platform ntawm qhov tsis nyob ntawm lub elevator, ua ntej, nws yuav tsum tau nruab, thiab qhov thib ob, nws yuav tsum muaj lub zog muaj zog, tuaj yeem tiv taus qhov cuam tshuam ntawm of the elevator's rated load, thiab ua si tsis muaj zog. luag hauj lwm. Thiab tam sim no ntau qhov chaw tsim kho, txawm hais tias qee qhov tau teeb tsa, tab sis tsis txaus los ua lub luag haujlwm tsis txaus, tsis muaj qhov tsis muaj nyob rau ntawm qhov chaw tsim kho, qhov no yog qhov tsis ncaj ncees lawm, Kuv vam tias tus neeg siv yuav xyuam xim rau kev tshuaj xyuas thiab ua. tsis txhob underestimate kab kawg ntawm kev tiv thaiv.
