Burton - yog dab tsi? Hauv paus ntsiab lus ntawm lub lag luam. daim ntawv thov

Lub mechanization ntawm lifting hauj lwm yeej ib txwm tau ib tug tseem ceeb. Nyob rau hauv kev twb kev txuas nrog rau qhov no ib pliag dhau los nws twb yees ua ntaus ntawv, uas tau pab mus rau teeb meem loj nyem ntawm lub cev ua zog neeg ua hauj lwm muab kev koom tes nyob rau hauv lub khiav hauj lwm ntawm lifting los yog txo ib tug ntau yam ntawm kev kawm. Lub npe ntawm no ntaus ntawv - Burton. Yuav ua li cas nws yog, peb yuav saib nyob rau hauv no tsab xov xwm.

Keeb kwm ntawm creation thiab txhais

Tsis muaj leej twg yeej paub, tab sis thaum nws tau tshwm sim los pib ua hauj lwm machinery tau tsiv mus nyob hnyav khoom nyob rau hauv qhov chaw. Thawj daim ntawv: Burton (nws yog dab tsi, yuav tau ua sai li sai kev nyeem) - blocks thiab hlua system, uas tso cai rau ho piv thiab kom lub tswv yim npaj ua ub no nrog tus heavy-hnyav khoom.

Txoj kev tshawb no ntawm tej monuments li cov pyramids ntawm Cheops nyob rau hauv Egypt, cov Great phab ntsa ntawm Tuam Tshoj , thiab lwm yam uas muaj hnub nyoog-laus lug unambiguously pom zoo hais tias tackles, lub hom phiaj thiab cov uas yuav tau los sib tham li hauv qab no ntaus ntawv tau invented txhiab xyoo dhau los. Nws yog ib heev cuab kev tias lawv tau Ameslikas yus txheej thaum ub.

lus qhia dav dav

Cia peb sim ntau li ntau tau mus kawm nyob rau hauv kom meej Burton. Yuav ua li cas yog nws los ntawm ib tug kev taw tes ntawm view? Inherently nws nruab nrab yog ib pawg ntawm cov blocks sau nyob rau hauv ib tug tshwj xeeb yas dhos, los ntawm kev uas kis tau ib cov saw los yog hlua. Qhov yooj yim Burton - ib block ntawm lub outstretched los ntawm cov traction caij. Xws li ib tug embodiment thiaj Circuit Court ob zaug ntsawj quab yuam yuav tsum tau kev tsiv cargo.

kev faib

Pulley blocks raug muab faib ua ob yam loj xws li: lub hwj chim thiab ceev. Feem ntau siv rau hauv kev xyaum hwj chim counterparts, yuav txo tau cov cable nro. Los ntawm txoj kev, qhov no dag zog yuav tsum xam yooj yim heev. Qhov no yuav tsum tau ib tug phua load hnyav rau cov uas twb muaj lawm multiplicity ntawm saw hoist. Cov lus nug tshwm sim: dab tsi yog qhov multiplicity? Teb: multiplicity - tus xov tooj ntawm ceg ntawm lub cev cwj pwm, uas yog ib tug luj rau lub zauv tus nqi ntawm cov ceg, uas yog twb kiav txhab nyob rau hauv lub nruas. Qhov no txhais siv tau rau lub hwj chim pulley. Hais txog kev ceev pulley, muaj yog ib tug multiplicity ntawm tus nqi tau los mus faib cov uas kawg ntawm txoj hlua ceev ntawm lub tsav ceev.

Nyob rau hauv high-ceev pulley kev khiav hauj lwm dag zog yuam yog thov mus rau mobile tawb, load, nyob rau hauv lem, yog tsau mus rau lub free kawg ntawm txoj hlua. Lub nce nyob rau hauv ceev thaum lub sij hawm ntawm txhais tes saw hoist ntawm no hom tshwm sim vim qhov kev ncua deb ntawm cov kev kawm lifting muaj peev xwm.

Zoom nyob rau hauv

Tackles (lo lus uas peb apparatus thiab lawv lub neej nyob rau lub xyoo yeej tseem unchanged) pub kev taw qhia los yog tshem tawm ntawm lub ntxiv system units. Vim rau qhov no, thiab muab cov uas yuav tsum tau piv. Yog hais tias lub multiplicity yog txawm, ces cov dawb kawg ntawm txoj hlua yog tsau rau ib tug ruaj ruaj yam ntxwv neeg. Yog hais tias multiplicity yog khib, ces tus tib kawg yog txuas mus rau lub tawb nrog ib tug nuv.

Lub hwj chim nce multiplicity pulley tso cai rau kom txo lub cheeb ntawm cov hlua thiab, raws li, lub nruas ntev thiab chav nyob. Tag nrho cov no nws thiaj li ua rau yus mus rau ib tug txo nyob rau hauv tag nrho cov loj ntawm lub tag nrho qhov system, ib tug yuav txo tau iav ratio. Tab sis nyob rau tib lub sij hawm nws yuav tsum tau ib tug zoo kawg thiab ntev ntawm txoj hlua.

Lub division rau tus xov tooj ntawm ceg

Burton (nws yog dab tsi, tam sim no koj tau obviously pom tau hais) yuav ua tau ib los yog ob, nyob ntawm seb muaj pes tsawg tus ceg. Nyob rau hauv thawj cov ntaub ntawv, lub saj zawg zog neeg tsiv raws lub nruas axis. Xws li ib tug embodiment muaj disadvantage nyob rau hauv ib tug undesirable hloov nyob rau hauv lub load rau ntawm cov nyiaj them yug nruas, nyob rau hauv lub qhaj ntawv ntawm free blocks (i.e., nrog rau kev tshem hlua ib zaug txhab rau ib tug nruas) qhov kev kawm yog tsiv tsis tau tsuas yog mas tab sis kuj horizontally.

Dual saw hoist yog ruaj ntawm ob hnub ntawm txoj hlua rau lub nruas. Ib qho piv txwv yog lub saw hoist winch. Nyob rau hauv kev txiav txim kom tsis txhob skewing tus nuv thov compensating units los yog balancers. Feem ntau cov feem ntau, xws li ib tug system yog ua Gantry los yog nyiaj siv ua haujlwm lifting cranes thiab hnyav cranes, ntauwd hom.

nta

Kiag li tej tsoo, uas lub hauv paus ntsiab lus ntawm kev txiav txim nyob rau hauv kev yog zoo li lub zog ua lag luam, nws yog ib qhov zoo vim hais tias nws tsis yuav tsum tau tus neeg siv yuav muaj tej kev txawj, tab sis yuav tsum tau mus yuav tau ceev faj heev vim hais tias, zoo li lwm yam lifting mechanisms, yog fraught nrog txaus ntshai thiab muaj peev xwm raug mob . Nyob rau hauv tas li ntawd, lub lag luam ntawm Pulleys qhia tau hais tias lub traction ntsiab yog siv nyob rau hauv lawv lub nruab tsis muaj ib qho zoo tagnrho yooj thiab muab tej txiaj ntsim nrog ib tug tej rigidity. Uas yog vim li cas ram-hlua ceg yog tsis muaj peev xwm instantly mus pw nyob rau hauv lub kwj tsev los yog nruas, thiab escapes lub ceg tsis tam sim ntawd ncaj. Qhov no yog qhov zoo tshaj plaws pom thaum lub siv steel ropes.

kev cai Pulley

Txhua phau ntawv saw hoist Nws ua hauj lwm nyob rau hauv lub hauv paus ntawm cov kev cai ntawm physics, thiab yog li ntawd nws txoj kev ua raws nkaus Ii mus rau ob peb haum kev cai yooj yim uas nws yog ntshaw kom tau ntsib.

• Txoj cai naj npawb ib. Winning nyob rau hauv ib lub dag zog los mus muab ib tug kws tsiv blocks los yog chais, uas yog tsau nyob rau hauv lub load los yog cov hlua ua los ntawm cov cargo. Nyob Ruaj Ruaj winning blocks nyob rau hauv qhov chaw yuav tsis muab.
• Txoj cai tooj ob. Winning lub ntau yam hwj huam tsis nyob rau hauv lub deb. Nyob rau hauv lwm yam lus, piv txwv li, ib tug muab ob npaug rau pulley thaiv los ua ke rau txhua tus meter khoom rov qab yuav tsum tau rub los ntawm nws tag nrho system ntawm ob meters ntawm txoj hlua. Nyob rau tib lub sij hawm Burton 6: 1 binds mus rub ntau tshaj 6 meters ntawm cable yuav tawm mus cargo mus txog ib Meter. Mus sum txog: qhov ntau "hwjchim" saw hoist, lub qeeb qeeb (kom ntau li ntau) yuav tsa loads.

Tshwj xeeb mloog yog muab ib tug tham saw hoist. Los ntawm nws tus kheej, nws yog ib tug txheej ntawm tej yam yooj yim pulley, txhua tus uas ua rau yus mus rau lwm lub. Yog li cov ob peb pulley thaiv yuav mounted. Qhov no hom yog feem ntau siv tau nyob rau lub sij hawm ntawm cawm.

Nyob rau hauv xaus yuav hais hauv qab no: saw hoist (kev khiav hauj lwm hauv paus ntsiab lus nws yog ib qho yooj yim txaus los to taub los ntawm ceev faj txoj kev tshawb no ntawm qhov teeb meem) yog, yog, thiab yog yuav mus yuav ib tug heev lub sij hawm ntev loyal neeg pab nyob rau hauv kev daws ntau nias teeb meem muaj feem xyuam rau cov kev siv, installation, chaw thau khoom, cov tsheb thauj khoom thiab lwm yam haujlwm uas yog es laborious. Cov ntsiab teeb meem, uas tshem tawm tsis niaj hnub no yog tsis tau vim, dua, tag nrho ua hauj lwm ntawm lub cev cov cai, yog muaj cov frictional rog nyob rau hauv lub system.
