Kusiyana pakati pa chain hoist ndi lever hoist

Ndi chiyanichain hoist: Hand chain hoist ndi yosavuta kugwiritsa ntchito, yosavuta kunyamula makina onyamulira pamanja 'angagwiritsidwe ntchito m'mafakitale atsopano, ma docks, malo otseguka opanda magetsi onyamula zinthu zolemetsa, zokweza zokoka pamanja zitha kugwiritsidwanso ntchito pakuthamanga. trolleys, kuyenda pa I-beam ndi mayendedwe ena.

Ndi chiyanilever hoist:Chingwe chonyamula dzanja ndi chosavuta kugwiritsa ntchito, chonyamulira chonyamulira pamanja. Ndi chogwirizira chamanja chomwe chimapeza mphamvu yolumikizira yomwe imagwirizana ndi katunduyo pogwiritsa ntchito mfundo ya lever, ndikuzungulira pa pliers ya katundu mkati mwake. kuyenda kuyendetsa katundu.

Kufanana: Onse unyolo chipika ndicrane lever hoistamagwiritsidwa ntchito kupulumutsa mphamvu posuntha ma pulleys.

Zosiyana

Chimodzi: chotchinga cham'manja ndi mawonekedwe okweza omwewo a kufananiza kwa voliyumu ya unyolo wa unyolo wamanja, chotchingira cham'manja ndi chaching'ono kwambiri kuposa cholumikizira unyolo, ndipo ntchito yake ndiyothandiza kwambiri ndipo mawonekedwe ake ndi okulirapo.

Chachiwiri: Kuyendetsa kwa chipika cha unyolo ndi unyolo wokoka pamanja, unyolo wamanja umayendetsa kuzungulira kwa pinion, pinion imayendetsa kuzungulira kwa gear, kutulutsa kwa torque, motero kukweza kulemera kwake, komwe kumagwiritsidwa ntchito kwambiri kukweza zinthu molunjika.

Atatu: ndibuku leverkwezanindi yaying'ono kwambiri kuposa chokwezera chonyamulira chomwechi, ndipo kagwiritsidwe kake ndi kambiri.Tsopano dzanja crane unyolo hoist angagwiritsidwe ntchito fakitale, migodi, ulimi, magetsi, kupanga nyumba ndi kumanga, docks, docks, nyumba yosungiramo makina unsembe, kunyamula katundu, Kutsegula galimoto ndi kutsitsa, etc Makamaka oyenera lotseguka ndi mphamvu- ntchito zopanda ntchito;ratchet lever hoist amagwiritsidwa ntchito kwambiri m'mafakitale ndi migodi, zoyendera, zomangamanga, mphamvu yamagetsi, kumanga zombo ndi nkhalango ndi m'madipatimenti ena a unsembe zida, lotayirira mbali bundling, kunyamula katundu, kumangitsa mizere ndi kuwotcherera malumikizanidwe ndi nthawi zina, makamaka pakalibe mphamvu. kaphatikizidwe ndi malo ang'onoang'ono okokera amawonetsa kukwera kwake kwapadera.

Chachinayi: Opareshoni ndi yosiyana

Lever hoist:

Umodzi: Theunyolo wa crane wamanjahoist idzakonza mbedza ndi kukhazikika kwa mphonda, ndipo mbedzayo idzapachikidwa pamodzi ndi chinthu cholemetsa chomwe chaimitsidwa.

Awiri: manual lever hoist heavy lifting.Kokani chikhomo ku "pamwamba" kwa mbale ya malo, kenaka kukoka chogwiriracho mobwerezabwereza, ndipo pamene chogwiriracho chikukokera mmbuyo ndi mtsogolo, kulemera kumakwera bwino.

Chachitatu: Kutsika kwa kulemera kwa mphonda ya pamanja.Ikani chikhomo pamalo "pansi" pachizindikirocho, kenaka kukoka chogwiriracho mobwerezabwereza, ndipo kulemera kwake kudzagwa bwino pamene chogwiriracho chikukoka.

Chachinayi: Kusintha kwa malo a mbedza ya wrench yamanja.Mukatsitsa, kokerani chubu ku "0" pa chizindikiro, ndiyeno mutembenuzire gudumu lamanja kuti musinthe malo apamwamba ndi apansi a mbedza ya tcheni kuti pawl yomwe imachotsa chingwecho, kuti malo a mbedza asinthe. mosavuta komanso mwachangu pokoka unyolo ndi dzanja.

Chain block:

Monga mtundu wokhazikika wa pulley yokhazikika, chotchinga chamanja cha pulley cholozera cholowa chonse cha zabwino za pulley yokhazikika, ndipo nthawi yomweyo imatengera kuphatikiza kwa chochepetsera cha reverse brake ndi gulu la chain pulley, ndi ma symmetrical makonzedwe a Kapangidwe ka spur gear rotation ndi kosavuta, kolimba komanso kothandiza. Chokweza chokokera pamanja chimazungulira pokoka unyolo wamanja ndi gudumu lachibangili kuti akanikizire ratchet ya friction blade ndi mpando wonyezimira kukhala umodzi ndikuzungulira palimodzi, ndipo tsinde lalitali la dzino limazungulira. blade gear, dzino lalifupi shaft ndi spline hole gear. Mwanjira iyi, sprocket yokweza yomwe imayikidwa pa spline hole gear imayendetsa unyolo wokweza, potero kukweza kulemera kwake bwino.Mbalame ya ratchet friction plate unidirectional brake imatengedwa, yomwe imatha kudzithyoka yokha pansi pa katundu, ndipo pawl imagwira ntchito ndi ratchet pansi pa kasupe, ndipo brake imagwira ntchito bwino.
