Burton - ndichiyani? Mfundo ntchito. ntchito

The mechanization kukweza ntchito wakhala patsogolo. Mogwirizana ndi chipangizo izi kanthawi kapitako izo kupangidwa, chimene chapangitsa mpumulo kwambiri antchito ntchito ya thupi nawo nchito za zochotsa kapena kutsitsa nkhani zosiyanasiyana. Dzina pogwiritsa - Burton. Chimene icho chiri, tiona m'nkhani ino.

Mbiri ya chilengedwe ndi tanthauzo

Palibe akuwadziwa, koma zinaoneka ndipo anayamba ntchito makina kusuntha zinthu zolemera m'malere. Choyamba akuti: Burton (icho chiri, Mukhozanso mwamsanga mabuku luso) - zotchinga ndi dongosolo chingwe, amene amalola kuti kwambiri wosalira ndi kufulumizitsa ntchito zomwe zinakonzedwa ndi zinthu heavy-kulemera.

Phunziro misewu monga mapiramidi a Cheops ku Egypt, Wamkulu Wall la China , ndi nyumba zina zaka zakubadwa unambiguously chikutsimikizira kuti otchinga, cholinga ndi tikambirana pansipa chipangizo anali anatulukira zaka zikwizikwi zapitazo. N'zoonekeratu kwambiri kuti iwo anali kale yodziwika achikale.

zambiri

Tiyeni kuyesa ngati kuli kotheka kuphunzira mwatsatanetsatane Burton. Kodi izo mwa mfundo luso bwanji? Tinabadwa amaimira gulu la midadada pamodzi mwini wapadera, kudzera wakupambana unyolo kapena chingwe. The Burton Chophweka - chipika wina ku wotambasula kudzera amafotokozera samatha. Chotero chimake ndi kuchepetsa dera kawiri anatsitsira mphamvu wofunikila kusuntha katundu.

Gawo

midadada Pulley anawagawa m'magulu awiri lalikulu mphamvu ndi liwiro. Amagwilitsidwa ntchito za m'gulu mchitidwe mphamvu, angathe kuchepetsa mavuto chingwe. Mwa njira, khama limeneli kuchita masamu mosavuta. Izi amafuna kugawanika katundu kulemera pa multiplicity alipo unyolo hoist. Funso ndi lakuti: kodi multiplicity? Yankho: multiplicity - chiwerengero cha nthambi za bungwe mtima, zomwe ndi kulemera kwa ubwino n'zosangalatsa kumva za nthambi, amene kale chilonda pa ng'oma ndi. tanthauzo Izi zikugwirizana ndi mphamvu pulley. Ponena liwiro pulley, pali multiplicity kufunika akamagwira kugawa mapeto otsogolera chingwe liwiro pa liwiro lotengeka.

Mu mkulu-liwiro mphamvu pulley opaleshoni umagwiritsidwa ntchito khola m'manja, katundu, nayenso chili ku mapeto ufulu a chingwe. The phindu mu liwiro pa Buku unyolo hoist wa mtundu uwu ukapezeka chifukwa mtunda wa mphamvu phunziro zochotsa.

Kuti mawonedwe mu

Tackles (zida kopita komanso moyo wawo zaka kwenikweni sichinasinthe) kulola oyamba kapena kuchotsa mayunitsi zina dongosolo. Chifukwa ichi, ndipo limapereka chiŵerengero amawathandiza. Ngati multiplicity ngakhale, ndiye ufulu mapeto a chingwe chili pa n'kupuma structural membala. Ngati multiplicity ali wosamvetseka, kenako mapeto womwewo Ufumuyo khola ndi mbedza.

Mphamvu kuwonjezeka multiplicity pulley zimathandiza kuchepetsa awiri a chingwe ndi moyenera, miyeso ng'oma ndi mayunitsi. Zonsezi n'kukumana ndi kuchepa mu misa okwana dongosolo lonse, kuchepetsa zida chiŵerengero. Koma nthawi yomweyo pamafunika kutalika kwambiri a chingwe.

Kudulidwa chiwerengero cha nthambi

Burton (icho chiri, tsopano inu mwachionekere anazindikira) akhoza kukhala osakwatira kapena awiri, malingana ndi kuchuluka kwa nthambi. Mbali yoyamba, membala kusintha ndi kuyenda ng'oma olamulira. Chotero chimake ndi ali ndi mwayi mu kusintha zosayenera katundu thandizo ng'oma, pakalibe midadada ufulu (i.e., ndi kuyimitsidwa chingwe kamodzi chilonda pa ng'oma a) nkhaniyo n'kufuna osati vertically komanso horizontally.

Wapawiri unyolo hoist ndi wotetezedwa ku malekezero onse a chingwe pa ng'oma ndi. Chitsanzo ndi unyolo hoist winch. Pofuna kupewa skewing mbedza agwiritsidwa ntchito akulipira mayunitsi kapena balancers. Nthawi zambiri, m'njira imeneyi ndi opareshoni gantry kapena pamwamba zochotsa cranes ndi cranes lolemera, nsanja mtundu.

Features

Mwamtheradi aliyense ndiphunzire, lomwe mfundo kanthu ambiri ofanana ntchito ndalezo, ndi bwino chifukwa sikutanthauza wosuta kuti luso lapadera, koma pamafunika kusamala chifukwa, ngati njira ina iliyonse zitsulo, ndi zinadzala ndi ngozi ndipo angathe kuvulaza . Komanso, ntchito pulleys limasonyeza kuti zinthu samatha ntchito machitidwe awo alibe kusinthasintha abwino ndi kuvekedwa ndi chinthu chimodzimodzi ena. N'chifukwa chake nkhosa chingwe nthambi sangathe yomweyo kugona mu mtsinje wagawo kapena ng'oma, ndi kuthaŵa nthambi siingathe yomweyo kuwongoka. Izi bwino ndinawona pamene ntchito zingwe zitsulo.

malamulo pulley

Aliyense unyolo hoist Buku Mozama pa maziko a malamulo a sayansi, choncho ntchito yake limafanana ndi malamulo angapo mwachilungamo wophweka amene ndi zofunika kuti adziwane bwino.

• Kulamulira nambala wani. Kuthana pofuna kupereka midadada mwapadera kusuntha kapena odzigudubuza, amene pa katundu kapena chingwe kutsogolera kuchokera katundu. N'kupuma Kopambana midadada mu malo sadzamva kupereka.
• Kulamulira lachiwiri. Kupambana angapo mphamvu imfa patali. M'mawu ena, mwachitsanzo, wachiphamaso pulley chipika msonkhano aliyense kuchira mita chinthu amafuna kukoka kupyolera dongosolo lake lonse mamita awiri a chingwe. Pa yomweyo Burton 6: 1 chimango kukokera mamita oposa 6 a chingwe kusuntha katundu mpaka mita imodzi. Kulonga n'cigwagwa kwambiri "mphamvu" unyolo hoist, ndi pang'onopang'ono (zambiri) adzathandiza katundu.

mwapadera wapatsidwa zovuta unyolo hoist. Paokha ndi ya pulley yosavuta, aliyense wa imbaenda wina. Motero pakati pa chipika angapo pulley akhoza wokwera. Mtundu nthawi zambiri ntchito pa nthawi ya kupulumutsidwa.

Pomaliza adzakhala kunena izi: unyolo hoist (zikugwira ntchito mfundo n'zosavuta zokwanira kuphunzira mosamala nkhani yomwe) anali, ali ndipo angakhale nthawi yayitali munthu wokhulupirika wothandizira kuthetsa mavuto ambiri kukanikiza zokhudzana pomanga, unsembe, potsegula, magalimoto ndi ntchito zina m'malo yolemetsa. The vuto lalikulu, lomwe kwathunthu kuthetsa lero si zotheka chifukwa, kachiwiri, ntchito yangwiro ya malamulo thupi, ndi pamaso pa magulu frictional mu dongosolo.
