Achipika, yomwe imatchedwanso pulley block, ndi chida chosavuta koma chosunthika chomwe chakhala chikugwiritsidwa ntchito kwa zaka mazana ambiri kukweza zinthu zolemera mosavuta. Zimapangidwa ndi kapule imodzi kapena zingapo zomwe zimayikidwa pa pulley kapena chimango chomwe chingwe kapena chingwe chimadutsamo. Mapuleti ndi gawo lofunikira pamakina ambiri ndipo amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza zomangamanga, zam'madzi ndi kupanga. M'nkhaniyi, tiwona ntchito, mitundu, ndi kagwiritsidwe ntchito ka pulley seti ndi gawo lawo popereka zabwino zamakina.
Ntchito ya pulley block
Ntchito yayikulu ya chipika cha pulley ndikupereka mwayi wamakina pochepetsa mphamvu yokweza chinthu cholemera. Izi zimatheka ndi kugawa kulemera kwa katundu pa ma pulleys angapo, potero kuchepetsa mphamvu yofunikira kukweza katunduyo. Ubwino wamakina woperekedwa ndi chipika cha pulley umatsimikiziridwa ndi kuchuluka kwa ma pulleys mu dongosolo. Mwachitsanzo, pulley yokhazikika yokhayokha imapereka mwayi uliwonse wamakina, pomwe makina okhala ndi ma pulleys angapo amatha kuchepetsa kwambiri mphamvu yonyamula katundu.
Mitundu ya ma pulley blocks
Pali mitundu yambiri ya midadada ya pulley, iliyonse yopangidwira ntchito zinazake komanso zofunikira zonyamula. Mitundu yodziwika kwambiri ya pulley block ndi:
- Pulley block yokhazikika: Mtundu uwu wa pulley uli ndi pulley yomwe imakhazikika pamapangidwe othandizira monga denga kapena mtengo. Imasintha njira ya mphamvu yomwe imagwiritsidwa ntchito pa katunduyo koma sapereka mwayi uliwonse wamakina.
- Kusuntha Pulley Block: Mu mtundu uwu wa pulley block, pulley imamangiriridwa ku katundu womwe ukukwezedwa, kulola wogwiritsa ntchito mphamvu yotsika. Pulley yosuntha imapereka mwayi wamakina pogawa kulemera kwa katundu pazingwe ziwiri zazitali.
- Chotchinga chophatikizika: Chotchinga chophatikizika chimapangidwa ndi timapuleti tambirimbiri tosanjidwa pamodzi ndi zotsekera zosasunthika ndi zotengera zosunthika. Mtundu uwu wa pulley block uli ndi ubwino wamakina apamwamba kuposa pulley imodzi yokhazikika kapena yosunthika.
- Grab Pulley: Pulley yogwira ndi mtundu wapadera wa pulley yopangidwira kugwiritsidwa ntchito ndi winchi kapena chipangizo china chokokera. Ili ndi mbali yokhotakhota yomwe imalola kuti chingwecho chilowetsedwe popanda kuyikapo pa chipikacho. Ma snatch blocks amagwiritsidwa ntchito kwambiri kukoka ndi kuchira.
Kugwiritsa ntchito pulley block
Mipiringidzo ya pulley imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa amatha kupereka zabwino zamakina ndikuthandizira kukweza zinthu zolemetsa. Zina zomwe zimagwiritsidwa ntchito popanga pulley block ndi:
- Makampani omanga: Mipiringidzo ya Pulley imagwiritsidwa ntchito kwambiri pantchito yomanga kukweza ndi kusuntha zida zomangira zolemetsa, monga midadada ya konkriti, matabwa achitsulo, zida zofolera, ndi zina zambiri. Ndizofunikira pakukweza zida ndi zida kumalo okwera ogwirira ntchito komanso kukakamira ndi kuteteza. zingwe ndi zingwe.
- Makampani Oyendetsa Panyanja: Mipiringidzo ya zombo zapamadzi zakhala zikugwiritsidwa ntchito panyanja kwa zaka mazana ambiri, makamaka m'zombo zapamadzi. Amagwiritsidwa ntchito kukweza ndi kutsitsa matanga, kukweza katundu, ndi kugwiritsa ntchito makina owongolera. M'machitidwe amakono akunyanja, ma pulley blocks amagwiritsidwa ntchito pochita ntchito zosiyanasiyana kuphatikiza kukokera, kukoka ndi kukweza zida zolemetsa pa zombo ndi nsanja zakunyanja.
- Kupanga ndi Kusungirako Malo: Mipiringidzo ya pulley imagwiritsidwa ntchito popanga ndi kusungirako zinthu kukweza ndi kusuntha makina olemera, zida ndi zida. Nthawi zambiri amaphatikizidwa m'makina apamwamba komanso zida zogwirira ntchito kuti athandizire kuyenda bwino kwa katundu mkati mwa malo.
- Kupanda msewu ndi kuchira: Pazochitika zapamsewu ndi kuchira, chipika cha pulley chimagwiritsidwa ntchito molumikizana ndi winch kuti athandizire kuchira kwagalimoto, kukoka ndi kufufuza kunja kwa msewu. Ma snatch blocks, makamaka, ndi ofunikira pakusintha kolowera ndikuwonjezera mphamvu yokoka ya winchi m'malo ovuta.
Ubwino Wamakina a Pulley Blocks
Ubwino umodzi wogwiritsa ntchito midadada ya pulley ndikuti amapereka mwayi wamakina womwe umalola wogwiritsa ntchito kukweza zinthu zolemetsa mosavuta. Ubwino wamakina wa chipika cha pulley chimadalira kuchuluka kwa zingwe zomwe zimathandizira katunduyo komanso kuchuluka kwa ma pulleys mu dongosolo. Pamene kuchuluka kwa zingwe ndi ma pulleys kumawonjezeka, momwemonso ubwino wamakina, zomwe zimapangitsa kuti zikhale zosavuta kukweza zinthu zolemetsa.
Ubwino wamakina woperekedwa ndi pulley block ukhoza kuwerengedwa pogwiritsa ntchito njira iyi:
Ubwino wamakina = kuchuluka kwa zingwe zothandizira katundu
Mwachitsanzo, pulley block yokhala ndi zingwe ziwiri zothandizira katunduyo idzapereka phindu la makina a 2, pamene pulley block yokhala ndi zingwe zinayi zothandizira katunduyo idzapereka phindu la makina a 4. Izi zikutanthauza kuti mphamvu yofunikira kukweza katunduyo imachepetsedwa. ndi chinthu chofanana ndi phindu lamakina.
Kuphatikiza pakupereka zabwino zamakina, midadada ya pulley imatha kuwongolera mphamvu, kuwalola kukweza katundu molunjika kapena mopingasa, kapena kuwongolera mphamvu mozungulira zopinga kapena ngodya.
Pulley midadadandi zida zofunika zomwe zimapereka ubwino wamakina ndikuthandizira kukweza zinthu zolemetsa m'mafakitale osiyanasiyana. Mapangidwe ake osavuta koma ogwira mtima amapangitsa kuti ikhale yosunthika komanso yofunikira pamagwiritsidwe osiyanasiyana, kuyambira pakumanga ndi ntchito zakunja mpaka kupanga ndi kukonzanso zinthu zakunja. Kumvetsetsa ntchito, mitundu, ndi kagwiritsidwe ntchito ka pulley blocks ndikofunikira kuti muzigwiritsa ntchito moyenera komanso motetezeka m'malo osiyanasiyana. Kaya amagwiritsidwa ntchito m'makonzedwe osavuta okhazikika a pulley kapena ngati gawo la zovuta za pulley system, ma pulley block akadali ndi gawo lofunikira pamakina amakono.
