Maulalo ndi mphete ndi mtundu wofunikira kwambiri wa zida zopangira zida, zomwe zimangokhala ndi lupu limodzi lachitsulo.Mwina mwawonapo mphete ya master itagona mozungulira shopu kapena ulalo wa oblong utapachikidwa pa mbedza ya crane.Komabe, ngati ndinu watsopano kumakampani opanga zida kapena simunagwiritsepo ntchito ulalo kapena mphete, sizingakhale zomveka bwino chifukwa chake zida zosavutazi ndizofunika kwambiri pakukweza chokweza.
Tawona kuti zikafika pamalumikizidwe ndi mphete, zambiri zenizeni komanso zaukadaulo zimapezeka pa intaneti.Komabe, zambiri zazomwe zidazi ndi zomwe zimagwiritsidwa ntchito ndizosowa.
Kwa makasitomala kunja uko omwe angakhale atsopano kuzinthu zokhudzana ndi kuba, kuyambira ndi mfundo zoyambira komanso zogwiritsa ntchito ndizofunikira musanalowe muzinthu zovuta kwambiri.Ndichifukwa chake talemba nkhaniyi.
M'nkhaniyi, mungayembekezere kuphunzira:
• Kodi maulalo ndi mphete ndi chiyani komanso zomwe zimagwiritsidwa ntchito
• Kodi mitundu yosiyanasiyana ya maulalo ndi mphete ndi chiyani?
• Maulalo ndi mphete zolembera / chizindikiritso
• Kuchotsedwa kwa maulalo ndi mphete ku mfundo zautumiki
1. Kodi Maulalo ndi mphete ndi chiyani?
Maulalo ndi mphete ndizofunika koma ndizofunikira pakukweza ndi kukonza mapulogalamu.Ndizida zotsekeka-zofanana ndi diso-zomwe zimagwiritsidwa ntchito kupanga malo olumikizirana pamisonkhano yolumikizira ndi gulaye kuphatikiza.unyolo slings, gulaye zingwe zamawaya, gulayeni, ndi zina zotero.
Maulalo ndi mphete zimagwiritsidwa ntchito ngati malo olumikiziranamagulu angapo a gulaye miyendo—nthawi zambiri unyolo kapena waya.Atha kugwiritsidwa ntchito ngati polumikizira masinthidwe a mwendo umodzi, ziwiri, zitatu, kapena zinayi.
Maulalo ambuye ndi mphete - maulalo ambuye a oblong, mphete za master, ndi maulalo owoneka ngati mapeyala - amatchulidwanso ngati mphete zosonkhanitsa kapena maulalo otolera, chifukwa "amasonkhanitsa" miyendo yambiri yoponyera mu ulalo umodzi.
Kuphatikiza pa kugwiritsidwa ntchito pamisonkhano ya gulaye, maulalo ndi mphete zitha kugwiritsidwanso ntchito ngati malo olumikizirana pakati pa pafupifupi magawo awiri aliwonse a msonkhano wolumikizira.Mwachitsanzo, mutha kugwiritsa ntchito ulalo kapena mphete kulumikiza:Kumanga unyolo ku mbedza ya crane,Pewani ku mbedza,Lumikizani ku mbedza
2. Mitundu ya Maulalo ndi mphete
Pali mitundu ingapo ya maulalo ndi mphete zomwe zingagwiritsidwe ntchito pagulu.Mitundu yogwiritsidwa ntchito kwambiri ya maulalo ndi mphete ndi:Oblong master link,Master link sub-assemblies,Maulalo okhala ngati peyala,Master mphete,Zogwirizana
Maulalo ambuye a Oblong angagwiritsidwenso ntchito kulumikiza unyolo ku mbedza ya crane, mbedza ku unyolo, ndi misonkhano ina yosiyanasiyana yolumikizira.
Ma sub-assemblies amakhala ndi maulalo awiri olumikizirana omwe amalumikizidwa ndi ulalo wa oblong master.M'malo momangirira miyendo inayi yoponyera pa ulalo waukulu, imatha kugawidwa pakati pa maulalo ang'onoang'ono.
Kugwiritsiridwa ntchito kwa magulu ang'onoang'ono kumathandiza kuchepetsa kukula kwa ulalo wa master-malumikizidwe akuluakulu kwambiri amatha kukhala oposa 3 mainchesi m'mimba mwake-pamene akukhalabe ndi Working Load Limit (WLL) yofanana ndi ulalo waukulu kwambiri.
Maonekedwe a peyala a maulalo awa amawapangitsa kukhala abwino kugwiritsidwa ntchito ndi mbedza zopapatiza kwambiri.Nthawi zina, ulalo wooneka ngati peyala udzakhala wokwanira bwino kuposa ulalo wa master oblong, womwe umachotsa kusuntha kwa katundu kuchokera mbali ndi mbali pamwamba pa mbedza.
Mawonekedwe ozungulira a mphete ya masters amapangitsa kuti ikhale yocheperako kuposa ulalo wa oblong master wolumikizana ndi ndowe zazikulu, zakuya za crane.Mphete zapamwamba zimagwiritsidwa ntchito nthawi zambiri popanga kapena m'mashopu ang'onoang'ono am'makina ndipo sizigwiritsidwa ntchito kawirikawiri.Nthawi zambiri, ulalo waukulu wa oblong ukhoza kuyikidwa m'malo mwake.
Ulalo wolumikizira ukhoza kukhala wamakina kapena wowotcherera ndipo amagwiritsidwa ntchito makamaka kulumikiza gawo la unyolo ndi ulalo waluso kapena wokokera.Zitha kugwiritsidwanso ntchito kupanga kulumikizana pakati pa maulalo apamwamba, ndowe, kapena zidutswa zina za Hardware.
Maulalo olumikizirana okokedwa, monga ulalo wina uliwonse mu unyolo, amalumikizidwa ndi ulalo waukulu kapena kumaliza koyenera ndikutsekeka kuti apange kulumikizana.
Chithunzi chomwe chili mugawoli chikuwonetsa njira ziwiri zosiyana zolumikizirana zowotcherera zingagwiritsiridwe ntchito.Pachithunzi chakumanzere, ulalowo umalumikizidwa kwamuyaya ndi mbedza yamaso ndipo umagwiritsidwa ntchito kulumikiza chipangizocho ndi ndowe yozungulira.Kumanja, maulalo olumikizirana okokedwa amagwiritsidwa ntchito kuti ateteze miyendo ya maunyolo ndikugwira mbedza ku ulalo wa master.
Hammerlok® Yosonkhanitsidwa ndi Kuphwanyidwa
Mayina atatu odziwika bwino a maulalo olumikizana ndi makina ndi awa:
• Hammerlok® (mtundu wa CM)
• Kuplex® Kuplok® (Peerless brand)
• Lok-a-Loy® (mtundu wa Crosby)
A Kuplex® Kupler®, yomwenso ndi Peerless product, ndi mtundu wina wodziwika bwino wamakina olumikizirana.Maulalo olumikizana awa ali ndi mawonekedwe osiyana pang'ono ngati unyolo.Pali theka limodzi lokha la thupi lomwe kulumikizana kumapangidwa ndi pini yonyamula katundu ndi pini yosungira.Popeza palibe magawo awiri a thupi, Kuplex® Kupler® simalumikizana pakati.
Chain Sling Assembly Pogwiritsa Ntchito Maulalo Angapo a Kuplex® Kupler®
3. Maulalo ndi mphete Zolemba / Chizindikiritso
Malinga ndi ASME B30.26 Rigging Hardware, ulalo uliwonse, master link subassembly, ndi mphete zizilembedwa mokhazikika ndi wopanga kuti aziwonetsa:
• Dzina kapena chizindikiro cha wopanga
• Kukula kapena kuvotera katundu
• Kalasi, ngati chofunika kudziwa katundu oveteredwa
4. Maulalo ndi mphete Kuchotsa ku Mfundo za Utumiki
Pakuwunika, chotsani maulalo aliwonse, ma master link sub-assemblies, ndi mphete kuti mugwiritse ntchito ngati zilizonse zomwe zalembedwa mu ASME B30.26 Rigging Hardware zilipo.
• Chizindikiritso chosowa kapena chosadziwika bwino
• Zizindikiro za kuwonongeka kwa kutentha, kuphatikizapo weld spatter kapena arc strike
• Kuboola kwambiri kapena dzimbiri
• Zopindika, zopotoka, zotambasulidwa, zotalikirana, zosweka, kapena zosweka zonyamula katundu.
• Ma nick kapena gouges mopambanitsa
• Kuchepetsa kwa 10% kwa gawo loyambirira kapena lamakatalo nthawi iliyonse
• Umboni wa kuwotcherera kapena kusinthidwa kosaloledwa
• Zinthu zina, kuphatikizapo kuwonongeka kowonekera komwe kumayambitsa kukaikira ngati kupitiriza ntchito
Ngati zina mwazomwe zili pamwambazi zilipo, chipangizocho chiyenera kuchotsedwa kuntchito ndipo chidzabwezeredwa kuntchito ngati / chivomerezedwa ndi munthu woyenerera.
5. Kuzikulunga
Tikukhulupirira kuti nkhaniyi yakuthandizani kuti mumvetsetse zomwe maulalo ndi mphete ndi chiyani, zomwe zimagwiritsidwa ntchito, komanso zizindikiritso ndi njira zowunikira mu ASME B30.26 Rigging Hardware.
Kuti tifotokoze mwachidule, maulalo ndi mphete zimakhala ngati malo olumikizirana nawo pamisonkhano yolumikizira kapena kusonkhana kwamiyendo yambiri.Ngakhale pali mitundu ingapo yamalumikizidwe ndi mphete zomwe zimagwiritsidwa ntchito popangira zida, maulalo a oblong master ndi osinthika kwambiri komanso omwe amagwiritsidwa ntchito ngati.mphete zosonkhanitsa.
Ulalo wolumikizira umagwiritsidwa ntchito kulumikiza magawo a unyolo ndi mphete yotengera kapena yotolera ndipo imatha kukhala yamakina kapena yowotcherera.
Monga chida china chilichonse chopangira zida, onetsetsani kuti mukutsatira miyezo yoyenera ya ASME ndikuchotsa pazofunikira zautumiki.
