Thaum peb tsom peb lub ntsej muag ntawm forklifts bustling txog hauv kev thauj khoom logistics niaj hnub, cov khub sturdy "caj npab"}} tus ntsuj plig ua haujlwm tag nrho. Txawm li cas los xij, cov lus nug, "Leej twg tsim lub nkhaus?" tsis muaj lus teb yooj yim. Nws tsis yog cov khoom ntawm ib qho, tam sim ntawd flash ntawm kev tshoov siab los ntawm ib zaj lus uas tsim, tab sis theej ib zaj dab neeg ntawm engineering eventiatyning thiab xav tau. Tshawb nrhiav lub hauv paus ntsiab lus ntawm rab rawg qhia cov tapestry txuas ntxiv ntawm kev hloov tshiab, los ntawm cov levers rau pallet fornling cov cuab yeej siv.
Kev kaj ntug: los ntawm qib mus rau zawv zawg caj npab
If we broadly define the fork as "a protruding arm used to lift and move heavy objects," its history can be traced back to the earliest days of human civilization. Kev ua haujlwm thaum ub ua haujlwm tau ua lub ntsiab cai ntawm txoj kev siv ntawm kev tsim cov qauv zoo nkauj zoo li cov pyramids thiab phab ntsa loj. They used massive logs as rollers to move massive stones, a technique that already embodied the fundamental principles of the fork's "lifting" and "translating" functions.
Ib qho ntxiv rau cov piv txwv thaum ntxov tau tshwm sim hauv cov zej zog ua liaj ua teb thaum nruab nrab hnub nyoog thiab tom qab ntawd. Cov neeg ua liaj ua teb siv ob - log log lub laub hu ua "rab riam." Cov laub no muaj ob ntev, rau pem hauv ntej - ncua ntoo ntoo ncej nyob rau sab xub ntiag. Cov neeg ua haujlwm tsa thiab muab tso rau loads, xws li sacts ntawm grain lossis bales ntawm quav nyab, tom qab siv cov tsiaj thiab thawb cov tsiaj ntawm lub tawb nqa khoom los thauj lawv. Cov kab ntawv no, hauv ob qho haujlwm thiab ua, zoo sib xws li cov tub ntxhais mekork: ib khub ntawm cov caj npab uas siv los txhawb nqa lub nra. Txawm hais tias ua los ntawm cov ntoo thiab siv los ntawm tib neeg kev ua haujlwm, tus qauv tsim lub tswv yim twb tsim tau lawm.
20th caug xyoo hloov: Qhov txheej txheem ntawm pallets thiab yug ntawm lub forklift
Ntoo Daj npab daws qhov teeb meem ntawm cov teeb meem me me {0} Cov qib kev txhim kho tau tshwm sim thaum pib lub cav hluav taws xob, tab sis cov khoom siv hluav taws xob tau ua tiav
- Cov neeg muaj npe nrov ntawm Pallets: thaum Ntiaj Teb Kev Tsov Rog Zaum II, los tiv nrog kev tsis muaj peev xwm ntawm cov tub rog, cov phooj ywg txheej txheem txhawb nqa thiab qauv ntoo av nplaum. Pallets consolidated Spatterted Cargo mus rau hauv Unified, cov teeb tsa lub chaw tsim khoom. Qhov kev hloov no spawned ib qho tseem ceeb: yuav ua li cas zoo "ntxig" thiab "nqa" chav no? Kev tsim kev puas tsuaj ib txwm muaj thiab cov hlua cable tau siv tsis tau thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm chaw thau khoom nrawm thiab thauj khoom.
- Qhov kev hloov pauv ntawm forklift: thaum ntxov thaum ntxov xyoo pua 20, "platform truck" nrog platform Lifting ua haujlwm, tshwm sim los ntawm cov tsheb laij teb, tshwm sim hauv qee yam Hoobkas. Txawm li cas los xij, keeb kwm feem ntau yog tus cwj pwm ntawm "txiv ntawm forklift niaj hnub" rau cov kev koom tes ntawm ntau cov tuam txhab thiab cov tib neeg. Piv txwv li, Clark tau qhia lub tructractor, ib qho khoom siv tsheb laij teb, xyoo 1917, thiab tom qab muaj versions maj mam ua haujlwm nqa khoom siv. Nyob rau tib lub sijhawm, lwm cov chaw tsim khoom, xws li yale, qhia pom zoo ib yam li hluav taws xob thiab kev sib txuas nrog sab hauv forklifts. Ib qho kev sib txawv ntawm cov khoom siv thaum ntxov yog tias lawv txhua tus tau pib ua ke ntawm "diav" raws li cov qauv sib xyaw ua ke rau hauv kev nqa mast.
Yog li, "kev tsim txom" ntawm lub forklift tsis yog cais kev tshwm sim, tab sis es sib txig nrog kev loj hlob ntawm lub tswv yim tag nrho ntawm cov forklift. Nws tuaj yeem sib cav tias nws yog cov khoom lag luam uas yog cov khoom siv khawm cov khoom siv tam sim no, thaum daws cov khoom siv palletized, "sib xyaw ua ke thiab tsim cov khoom siv niaj hnub no.
Lub tshuab ua haujlwm ntawm niaj hnub fork: cov khoom siv precision ntawm "hlau tuav"
Raws li forklifts tau dhau los ua lub mainstay ntawm kev lag luam thoob ntiaj teb, ib qho zuj zus los ntawm cov hlau yooj yim rau hauv cov khoom siv ua haujlwm yooj yim. Kev tsim cov khoom siv niaj hnub yog qhov kev kos duab zoo heev uas sib xyaw cov ntaub ntawv kev tshawb fawb, kev suav txhua yam, thiab cov txheej txheem kev tsim kho.
- Cov Khoom Siv Hluav Taws Xob: Cov diav rawg ntxov yuav tau ua los ntawm cov pa roj carbon hlau zoo tib yam. Txawm li cas los xij, kom ntseeg tau lub zog thaum tswj kom muaj zog txaus, xws li siv 42crmo (42 chromium {}} molybdenum hlau). Cov hlau no ua tiav qhov kev ua kom sib npaug ntawm lub zog thiab tawv tom qab kev kho cua sov.
- Kev kho cua sov: Qhov no yog qhov tseem ceeb theem uas muab rab rawg nws tus ntsuj plig. Cov tshuaj lom zem uas raug ua kom nruj "quenching ua raws li los ntawm kev ntsuas kub ntxhov" kev kho cua sov. Quenching immarts lub zog muaj zog (feem ntau ncav cuag zog ntawm HRC 40-45), thaum tempering kev ntxhov siab sab hauv thiab tiv thaiv brittle begure nyob rau hauv hnyav cuam tshuam. Rab rawg uas tsis yog tsim kom zoo kub kho tau tuaj yeem txo nws cov peev xwm thauj khoom muaj peev xwm los ntawm ntau dua 50% thiab yuav raug tawg sai sai.
- Tsim thiab Kuaj: Diav Rawg Tsim yuav tsum ua kom nruj kev nyab xeeb thoob ntiaj teb kev nyab xeeb cov qauv, xws li lub teb chaws Yelemees ntawm GB / T 17910, thiab Tebchaws Asmeskas B56.1. Cov qauv tswj hwm tag nrho cov txheej txheem sib xyaw ua ke, los ntawm cov ntaub ntawv thiab tsim khoom lag luam los kuaj. Piv txwv li, cov qauv uas yuav tsum tau ua kom txhua rab rawg yuav tsum tiv thaiv qhov ntsuas ntawm 1.5 zaug tus ntsuas ntsuas tsis muaj kev ruaj ntseg thiab 3 zaug tus ntaus nqi thauj khoom yam tsis muaj kev tawg. Cov neeg lag luam feem ntau siv 100% sib nqus particle particle (MT) kom ntseeg tau tias txhua lub Hoobkas tau ua rau muaj kev qaug zog tsis ua haujlwm.
Xaiv txoj cai ntawm kev txawj ntse kom ntseeg tau kev nyab xeeb ua haujlwm -}} Cia siab rau kev sib tw
Saib rov qab ntawm cov evolution ntawm cov rawg los ntawm cov ntoo ntoo yooj yim rau qhov siab {} Tech tag nrho cov khoom siv, peb ua keeb kwm ntawm kev tsis txaus siab rau kev nyab xeeb thiab ua haujlwm. Niaj hnub no, thaum koj xaiv rab rawg, koj xaiv ntau dua li ib feem; Koj tseem xaiv lub luag haujlwm hnyav rau kev nyab xeeb thiab kev cog lus rau kev tsim khoom. Raws li cov kws tshaj lij kev lag luam nrog 20 xyoo ntawm kev paub hauv diav rawg kev tsim khoom, Helear (Jiuaye hlau) tob txog qhov hnyav ntawm lub luag haujlwm no. Peb ua raws li cov qauv kev lag luam German muaj kev xaiv (siv siab {{{{{{{{}}} {13}- Kev sim tshuaj. Txhua kauj ruam yog moviculously ua kom ntseeg tau tias txhua tus delfle lub thauj khoom muaj peev xwm ua kom nws muaj peev xwm tsis hloov pauv txawm tias nyob rau hauv 1.5 zaug qhov siab tshaj plaws load. Peb ua tsaug caw koj kom paub qhov ua tau zoo thiab muaj kev thaj yeeb nyab xeeb uas muaj kev sib raug zoo rau kev tsim cov kev txawj ntse rau koj lub chaw logistics rau koj lub logistist!
