Unyolo hoist - unyolo hoist ndi chipangizo ...

Burton - ndi njira imene katundu zitsulo. Amakhala ndi magulu chimodzi kapena zingapo midadada envelopu chingwe. Mawu "Burton" amachokera ku polyspastion Greek. Mawu amenewa amatanthauza "kukokera pa zingwe angapo." The Ntchito yaikulu ndi unyolo hoist ndi kuonjezera mphamvu onyamula ya zida chachikulu.

M'mawu ena, chipangizo amapereka phindu mu mphamvu. Komabe, zotsatira n'zosiyana ndi kuchepetsa ntchito unyolo hoist zochotsa liwiro. Mukhozanso kupambana liwiro chifukwa imfa ndi mphamvu. Koma ngati midadada pulley ntchito kwambiri kamodzikamodzi. Mulimonsemo, mfundo ya chipangizo tichipeza mu ndalezo kanthu.

chipangizo limagwirira

Burton - ndi zochotsa chipangizo, zomwe zimathandiza kuti mphamvu yoposa winch kangapo pa Nyamulani. M'mawu ena, limagwirira ichi kumawonjezera chipangizo katundu. Ntchito unyolo hoist limachititsa kukweza katundu wolemera ndi winch motero mphamvu yaing'ono. Nkofunika kukumbukira kuti liwiro kukweza nyumba katundu yafupika kwambiri monga kuti mwana'yo phindu mu mphamvu.

limagwirira kusankhidwa

Burton zingamuthandize kunyamula katundu wolemera ndi ntchito osachepera khama. Losavuta kapangidwe unyolo hoist lakonzedwa kuti m'mphepete imodzi chingwe amamangiriridwa ng'oma, ndi katundu inaimitsidwa ili kumapeto ina ya chingwecho. Zipangizo kukhala kapangidwe zovuta zambiri monga odzigudubuza angapo atathana ndi makina.

Pansi pa kulemera ayenera kuganizira kukula kwa zotchinga ndi chingwe awiri. Katundu ndi misa lalikulu, pamene atapachikidwa pa ukuwonjezeka chingwe katundu. Kwa limagwirira amenewa amakhala ndi avale mofulumira. Pankhaniyi, chofunika kuchepetsa voteji mu chingwe. Choncho, yopachikapo akatundu olemera ntchito awiri kapena anayi chingwe. Ndi zotheka kugwiritsa ntchito kapangidwe unyolo hoist zovuta.

Mfundo ntchito

Munthu, osati zokhudzana potsegula, dzina la limagwirira izi zovuta kumvetsa. Koma Ndipotu otchinga - ndi lophweka zochotsa limagwirira kuti angathe kumanga pafupifupi aliyense. Mfundo chipangizo ichi ndi losavuta kwambiri ndipo wakhala anaphunzira maphunziro kusukulu sayansi. Ndipo chiwembu cha amenewa yaing'ono "Kireni" Ndi yosavuta.

unyolo hoist kapangidwe zikuphatikizapo magulu angapo a midadada pamodzi mwini wapadera. Ndipo amatembenuka envelopu chingwe kapena chingwe. Ngakhale oterowo kapangidwe yosavuta angagwiritsidwe ntchito bwino ndithu kuonjezera mphamvu ntchito kwa kutsitsa kapena kukweza katundu. Komanso losavuta pulley chipika dongosolo limapangidwa mayunitsi katundu. Iwo akhoza kukhala a mitundu zotsatirazi:

• multiroll kapena Idler;
• lokhazikika kapena foni.

Kukoka chingwe mphamvu Pankhaniyi amadalira pa chiwerengero cha yarns chingwe ntchito pomanga.

Ziti zimene ntchito chipangizo?

Unyolo hoist kukumenyani ndi kusuntha katundu milandu pamene n'zotheka ntchito kokha mphamvu ya mwamuna ndi zochepa za njira thandizo. Komanso chintchito - n'chofunika zikuluzikulu za zingwe, cranes ndi njira zina mechanization.

Pachifukwa ichi, zipangizozi ntchito pafupifupi m'madera onse, kumene mu njira iliyonse ntchito kukweza njira: ku ntchito zapakhomo, kutsiriza ndi makampani lolemera.

Choncho pa zifukwa ziti ndi zomveka chintchito? The ntchito chipangizo izi zachokera lamulo adzakoka chokhethemulira, pamene kuwina tingati kupeza kutayikidwa patali. Popeza mfundo imeneyi ndi lophweka, kuti ndiphunzire ndi manja awo si kophweka. Muyenera awiri okha Idler unit.

Kukweza katundu kulemera zina ndi unyolo hoist m'pofunika kuyesetsa, theka la misa. Tisaiwale za kutalika kwa chingwe ntchito. Ziyenera kukhala kawiri kutalika kwa amene katundu pamwamba. Tikumbukenso kuti otchinga ndi chipangizo zophweka kwambiri wotchedwa "otchinga awiri kuti munthu", monga iwo kuonjezera mphamvu anagwira ndi theka. Kapangidwe ndi midadada atatu, motero amatipatsa chodziwa mphamvu katatu.

multiplicity unyolo hoist

Tikumbukenso kuti mawerengedwe a unyolo hoist ali ndi udindo wofunika kwambiri. Ndipotu, limagwirira si ntchito mu makhalidwe abwino. Izo poyera kuti mphamvu mikangano akuwuka pa kusamutsidwa kwa sheave chingwe. Komanso magulu mikangano amayambira pa kasinthasintha wa wodzigudubuza, ziribe kanthu zimene mayendedwe ntchito m'menemo.

Kudziwa kwamakokedwe mphamvu ntchito chingwe popanda zomvetsa chifukwa mikangano zofunika kulemera kwa katundu kugawidwa ndi multiplicity unyolo hoist. Pansi ayenera kumvetsa kuchuluka kwa chingwe chingwe akugwira katundu. Kapenanso tisamachite alephere kukhululukirana. Komanso ndiyo dzuwa la unyolo hoist.

Iwo akhoza kuchepetsa, ntchito apamwamba zotchinga ndi zingwe, komanso ndi ntchito Mkhalidwe precluding anaŵerama zosafunika ndi overlaps.

Chibwenzi ziwembu pulley anaphunzira ngakhale Maphunziro sayansi. Amathandiza kuti kumanga ichi sichichitika kwambiri. Komanso, zinthu zotsatirazi ayenera kugula:

• M'pake;
• chingwe;
• winch.

Kodi zitsanzo zipangizo alipo?

Kuti akonze chitsanzo yosavuta yekha amafuna chipika wina. Kugwiritsa ntchito njira limapereka kawiri phindu mu mphamvu. Izi zikutanthauza kuti kuchotsa katundu ayenera kugwiritsidwa ntchito khama kawiri zochepa. Komabe, mu nkhani iyi chingwe kukhala kawiri bola. Chotero unyolo hoist ali ndi chiŵerengero cha awiri wina. Chotero kapangidwe akhoza mulibe mayunitsi unyolo hoist, mwachizolowezi carbine akhoza kugwiritsidwa ntchito m'malo.

Pamene ntchito mu pulley mayunitsi awiri akhoza ziwonjezeke zitatu ntchito likukhudza mphamvu. Palinso ntchito ya ukonde chitetezo chimene kumayambika pamene chingwe ndi adatchithisira. Pankhaniyi, awiri omangika khamu zowalamulira ndi kutchinga katundu.

Ngati limagwirira yapita kuwonjezera awiri chipika zambiri, inu kupeza chipangizo unyolo hoist, kupereka phindu kanayi mphamvu. Chotero limagwirira ali ndi chiŵerengero cha zinayi. Mu njira iyi, kotala kulemera ndi kumapeto a chingwe, ndipo ena katundu - pa chingwe yokha.

chipangizo tackles

Tikumbukenso kuti kufala kwa mphamvu mu mawonekedwe woyera sizingatheke chifukwa yatsoka mphamvu frictional. Pamene chingwe rubs ndi chipika anataya khumi peresenti makumi awiri a mphamvu ntchito. Choncho, mu pulley losavuta kwenikweni chiŵerengero ndi za 1.8 makilogalamu pa makilogalamu katundu ayenera kukwezedwa. A 5 khola pulley chipika chimatulutsa phindu mu mphamvu pang'ono kuposa nthawi 3.

Ubale pamwamba limasonyeza kuti n'zotheka kuonjezera chiwerengero cha midadada unyolo hoist kwa malire ena, ndiye azisiyana angagwe. Komabe, kuti kuwonjezera chiŵerengero pazipita, mukhoza kugwiritsa ntchito chipangizo otchinga.

hoist Izi unyolo lakonzedwa m'njira amene anatambasula kulemera si kulenga katundu pa chipika lomaliza. M'malomwake, imangolongeza chingwe kuti umadutsa wagawo ndi. Chifukwa, pamene kutsatira chipika 3 alternately chikugwirizana tackles 2: 1 ndi 3: 1. Akuti izi zimapereka phindu chofutukuka pasanu ndi kamodzi mu mphamvu, komabe - mu nthawi 4,3.

Zochepetsera mikangano?

The vuto lalikulu unyolo hoist ndi mu ndondomeko iye amayenera kuti tilimbane ndi mizimu yoipa mikangano akuwuka. Vuto limeneli akhoza pang'ono anathana ndi ntchito zingwe apamwamba, midadada pulley, midadada ndi mitsinje yosalala, komanso mafuta.

Komanso, pali njira zina ndi ntchito yake ya kapangidwe unyolo hoist. Mwachitsanzo, ngati inu ntchito kuposa mfuti imodzi ndi awiri. Izi amachepetsa mphamvu frictional, ndipo pali ponso kink utali wozungulira.
