Athipa ea pulley, eo hape e bitsoang pulley block, ke sesebelisoa se bonolo empa se feto-fetoha le maemo se 'nileng sa sebelisoa ka makholo a lilemo ho phahamisa lintho tse boima habonolo. E na le pulley e le 'ngoe kapa tse ngata tse kenngoeng holim'a pulley kapa foreimi eo ho fetisoang thapo kapa thapo. Li-pulley blocks ke karolo ea bohlokoa ea litsamaiso tse ngata tsa mochini mme li sebelisoa liindastering tse fapaneng ho kenyelletsa kaho, tsa metsing le tsa tlhahiso. Sehloohong sena, re tla hlahloba mesebetsi, mefuta, le ts'ebeliso ea li-pulley sets le karolo ea tsona ho fana ka melemo ea mochini.
Mosebetsi oa pulley block
Mosebetsi o ka sehloohong oa thibelo ea pulley ke ho fana ka monyetla oa mochine ka ho fokotsa matla a hlokahalang ho phahamisa ntho e boima. Sena se finyelloa ka ho aba boima ba mojaro ho pholletsa le li-pulleys tse ngata, kahoo ho fokotsa matla a hlokahalang ho phahamisa mojaro. Molemo oa mochine o fanoang ke "pulley block" o khethoa ke palo ea li-pulleys tsamaisong. Ka mohlala, pulley e le 'ngoe e tsitsitseng ha e fane ka melemo ea mechine, athe tsamaiso e nang le li-pulleys tse ngata e ka fokotsa haholo matla a hlokahalang ho phahamisa mojaro.
Mefuta ea li-pulley blocks
Ho na le mefuta e mengata ea li-pulley blocks, e 'ngoe le e' ngoe e etselitsoe lits'ebetso tse ikhethileng le litlhoko tsa mojaro. Mefuta e tsebahalang haholo ea li-pulley block e kenyelletsa:
- Sebaka se tsitsitseng sa pulley block: Mofuta ona oa pulley block o na le pulley e tsitsitseng mohahong o tšehetsang joalo ka siling kapa sefate. E fetola tataiso ea matla a sebelisoang ho mojaro empa ha e fane ka melemo leha e le efe ea mochine.
- Moving Pulley Block: Mofuteng ona oa pulley block, pulley e khomaretsoe mojaro o phahamisoang, e lumellang mosebedisi ho sebelisa matla a tlaase. Sebaka se tsamaeang sa pulley se fana ka monyetla oa mochine ka ho aba boima ba mojaro holim'a bolelele ba liropo tse peli.
- Li-pulley block tse kopantsoeng: Sebaka sa pulley se kopantsoeng se entsoe ka li-pulleys tse ngata tse hlophisitsoeng hammoho le li-pulleys tse tsitsitseng le li-pulleys tse tsamaeang. Mofuta ona oa pulley block o na le melemo e phahameng ea mochini ho feta pulley e le 'ngoe e tsitsitseng kapa e tsamaeang.
- Grab Pulley: Pulley ea ho tšoara ke mofuta o khethehileng oa pulley block e etselitsoeng ho sebelisoa ka winch kapa sesebelisoa se seng sa ho hula. E na le phanele ea mahlakoreng e nang le hinged e lumellang khoele hore e kenngoe ntle le ho e kenya ka har'a boloko. Li-snatch blocks li atisa ho sebelisoa bakeng sa ho hula le ho tsosolosa.
Ho sebelisoa ha pulley block
Li-pulley blocks li sebelisoa haholo liindastering tse fapaneng ka lebaka la bokhoni ba tsona ba ho fana ka melemo ea mochini le ho thusa ho phahamisa lintho tse boima. Lisebelisoa tse ling tse tloaelehileng bakeng sa li-pulley blocks li kenyelletsa:
- Indasteri ea kaho: Li-pulley blocks li sebelisoa haholo indastering ea kaho ho phahamisa le ho tsamaisa thepa e boima ea kaho, joalo ka litene tsa konkreite, maballo a tšepe, lisebelisoa tsa marulelo, joalo-joalo. likhoele le lithapo.
- Indasteri ea Maritime: Li-pulley blocks li 'nile tsa sebelisoa likopong tsa maoatleng ka makholo a lilemo, haholo-holo likepeng tsa likepe. Li sebelisetsoa ho phahamisa le ho theola liseile, ho phahamisa thepa, le ho tsamaisa lisebelisoa tsa ho qhekella. Ts'ebetsong ea sejoale-joale ea kantle ho naha, li-pulley blocks li sebelisetsoa ho etsa mesebetsi e fapaneng e kenyelletsang ho tsubella, ho hula le ho phahamisa lisebelisoa tse boima likepeng le liforomong tsa kantle ho naha.
- Ho etsa le ho boloka thepa: Li-pulley blocks li sebelisoa meahong ea tlhahiso le ea polokelo ho phahamisa le ho tsamaisa mechini e boima, lisebelisoa le thepa. Hangata li kenyelelitsoe tsamaisong ea li-crane tse holimo le lisebelisoa tsa ho sebetsana le thepa ho thusa ho tsamaisa thepa ka katleho ka har'a setsi.
- Ho tloha tseleng le ho hlaphoheloa: Ts'ebetsong ea kantle ho tsela le ea ho hlaphoheloa, sethala sa pulley se sebelisoa hammoho le winch ho thusa ho khutlisa koloi, ho hula le ho hlahloba kantle ho tsela. Li-snatch blocks, haholo-holo, li bohlokoa bakeng sa ho fetola tsela ea tow le ho eketsa matla a ho hula a winch sebakeng se thata.
Melemo ea Mechini ea Pulley Blocks
E 'ngoe ea melemo ea mantlha ea ho sebelisa li-pulley blocks ke hore li fana ka monyetla oa mochini o lumellang mosebelisi ho phahamisa lintho tse boima habonolo. Molemo oa mochine oa "pulley block" o itšetlehile ka palo ea liropo tse tšehetsang mojaro le palo ea li-pulleys tsamaisong. Ha palo ea liropo le li-pulleys li ntse li eketseha, ho joalo le ka melemo ea mechine, ho etsa hore ho be bonolo ho phahamisa lintho tse boima.
Melemo ea mochini e fanoeng ke "pulley block" e ka baloa ka mokhoa o latelang:
Molemo oa mochine = palo ea liropo ho tšehetsa mojaro
Ka mohlala, mokoloko oa pulley o nang le liropo tse peli tse tšehetsang mojaro o tla fana ka melemo ea mechine ea 2, athe pulley block e nang le lithapo tse 'nè tse tšehetsang mojaro e tla fana ka melemo ea mechine ea 4. Sena se bolela hore matla a hlokahalang ho phahamisa mojaro a fokotsehile. ka ntlha e lekanang le molemo oa mochine.
Ntle le ho fana ka melemo ea mochini, li-pulley blocks li ka tsamaisa matla hape, tsa li lumella ho phahamisa meroalo ka ho otloloha kapa ho ea holimo, kapa ho tsamaisa matla ho potoloha litšitiso kapa likhutlong.
Li-pulley blockske lisebelisoa tsa bohlokoa tse fanang ka melemo ea mochini le ho thusa ho phahamisa lintho tse boima liindastering tse fapaneng. Moralo oa eona o bonolo empa o sebetsa hantle o e etsa hore e sebetse ka tsela e fapaneng le ea bohlokoa bakeng sa lits'ebetso tse fapaneng, ho tloha ts'ebetsong ea kaho le kantle ho naha ho isa ho ho etsa thepa le ho e sebelisa hape ntle le litsela. Ho utloisisa mesebetsi, mefuta le ts'ebeliso ea li-pulley blocks ho bohlokoa ho li sebelisa ka nepo le ka polokeho libakeng tse fapaneng. Ho sa tsotellehe hore na e sebelisoa ka mokhoa o bonolo o tsitsitseng oa pulley kapa e le karolo ea tsamaiso e rarahaneng ea pulley, li-pulley blocks li ntse li phetha karolo ea bohlokoa mosebetsing oa morao-rao oa mochine.
