Ngaba isixhobo sokukhusela umthwalo ogqithisileyo wekhonkco lesandla sokunyuswa kwekhonkco lesandla lithintela izinto ezinzima ekuweni?

Uhlalutyo lokukhuselwa kwesixhobo sokukhusela i-hand chain hoist overload ukukhusela izinto ezinzima ukuba zingawi

I. Intshayelelo
Njengesixhobo esiqhelekileyo sokuphakamisa ngesandla,isandla chain hoistszisetyenziswa kakhulu kwimizi-mveliso, imigodi, iindawo zokwakha, iidokhi, iindawo zokugcina iimpahla kunye nezinye iindawo zokufaka oomatshini kunye nokunyusa iimpahla, ngakumbi kwimisebenzi evulekileyo kunye nengenamandla. Nangona kunjalo, ngexesha lokusetyenziswa, ukuba ukugqithisa kwenzeka, kunokukhokelela kwimiphumo emibi, njengomonakalo wezixhobo, izinto ezinzima eziwayo, njl., ezibeka engozini ukhuseleko lwabasebenzi kunye nepropati. Ke ngoko, isixhobo sokukhusela umthwalo ogqithisiweyo wekhonkco lesandla sibalulekile ukukhusela izinto ezinzima ukuba zingawi.

II. Umgaqo wokusebenza we-hand chain hoist
I-hand chain hoist itsala ikhonkco le-manual kunye nevili letsheyina lesandla ukuze lijikeleze, licinezela i-ratchet yepleyiti ye-friction kunye nesihlalo se-brake ibe ngumzimba omnye kwaye ijikeleze kunye, kwaye i-axis ende yezinyo ijikeleza i-plate gear, i-axis emfutshane yezinyo kunye ne-spline hole gear. Ngale ndlela, i-sprocket yokuphakamisa efakwe kwi-spline hole gear iqhuba ikhonkco yokuphakamisa, ngaloo ndlela iphakamisa into enzima kakuhle. Ipleyiti ye-ratchet friction plate yohlobo lwendlela enye ibrake inokuzibophelela phantsi komthwalo. I-ratchet idibanisa ne-ratchet phantsi kwesenzo sentwasahlobo, kwaye i-brake isebenza ngokukhuselekileyo.

3. Umgaqo kunye nomsebenzi wesixhobo sokukhusela umthwalo ogqithisileyo
Umgaqo wokusebenza
Isixhobo sokukhusela i-overload ye-hand chain hoist ngokuqhelekileyo ibandakanya i-nut brake, i-sleeve, i-lock nut, i-disc spring, i-pressure plate, i-friction plate kunye nezinye izinto. Ngexesha lokusebenza okuqhelekileyo, ikhonkco lesandla liqhuba ivili lekhonkco lesandla ukuze lijikeleze. Itorque yevili letsheyina lesandla ingaphantsi kokukhuhlana phakathi kwepleyiti yokukhuhla kunye nevili letsheyina lesandla. I-torque idluliselwa kwi-shaft ende nge-nut ye-brake, kwaye ivili letsheyina lesandla lijikeleza kunye ne-nut ye-brake kunye ne-shaft ende. Xa usebenza phantsi komthwalo ogqithisileyo, i-torque esetyenziswa kwivili letsheyina lesandla inkulu kune-friction force, kwaye ukutyibilika kwenzeka phakathi kwevili lekhonkco lesandla kunye nepleyiti yokukhuhlana. I-torque ayikwazi ukuhanjiswa ngokufanelekileyo kwi-nut nut, ngaloo ndlela inqanda ukusebenza phantsi komthwalo onzima.
Umsebenzi
Thintela ukunyuswa komthwalo omninzi: Isixhobo sokukhusela umthwalo omninzi senziwe salungiswa phambi kokuba siphume kumzi-mveliso. Xa umda wokulayisha owenziwe ngaphambili, oko kukuthi, amaxesha angama-1.2 umthwalo, ugqithisiwe, isixhobo sokukhusela siyasebenza. Ngeli xesha, ikhonkco lesandla liya kuvalwa, ukunyuswa kuya kuvalwa, kwaye ukuhla kuphela kunokwenzeka.
Khusela ukhuseleko lwezixhobo: Isixhobo sokukhusela i-overload inokuthintela ngokufanelekileyo umonakalo owonakalisayo kwisixhobo esibangelwa ukugqithiswa, njengokunyuka kwekhonkco ukufikelela kumda kunye nokuphuka, njl., ukukhusela ukhuseleko lwezixhobo kunye nokwandisa ubomi benkonzo yezixhobo.
Qinisekisa ukhuseleko lwabasebenzi: Isixhobo sokukhusela umthwalo ogqithisileyo sinokubona ukulayisha ngaphezulu kwangexesha kwaye sikhuphe isilumkiso sokukhumbuza umqhubi ukuba athathe amanyathelo akhawulezileyo ukuphepha iingozi ezibangelwa zizinto ezinzima eziwayo.

4. Ingaba isixhobo sokhuselo lomthwalo ogqithisiweyo wekhonkco lesandla sokunyuswa kwekhonkco lithintela izinto ezinzima ekuweni?
Indlela yokuthintela ukuba izinto ezinzima zingawi
Ukuqhawuka ngoko nangoko kwesiqhoboshi: Isixhasi setyathanga lesandla sithatha ipleyiti ye-ratchet friction plate yendlela enye, enokuthi iqhawuke ngokuzenzekelayo phantsi komthwalo. I-ratchet idibanisa ne-ratchet phantsi kwesenzo sentwasahlobo ukwenza i-brake isebenze ngokukhuselekileyo. Xa ixinzelelwe kakhulu, ibrake iya kubhuleka ngoko nangoko ukunqanda ukuba izinto ezinzima zingawi.
Ukukhuselwa kwe-slip yesixhobo sokukhusela umda womthwalo: Xa isixhobo sokukhusela ukulayisha ngaphezulu sigcwele, i-slippage iyenzeka phakathi kwevili le-chain chain kunye neplate ye-friction, kwaye i-torque ayikwazi ukuhanjiswa ngokufanelekileyo kwi-nut ye-brake, ngaloo ndlela igwema umsebenzi phantsi kweemeko ezigqithisiweyo. Ngeli xesha, into enzima ayiyi kuqhubeka iphakanyiswa, kwaye ayiyi kuwa.
Ukusebenza kwizicelo ezibonakalayo
Kwizicelo ezisebenzayo, isixhobo sokukhusela umthwalo ogqithisiweyo we-hand chain hoist inokuthintela ngokufanelekileyo into enzima ukuba ingawi. Umzekelo, ihuku yeFalcon Heavy Industry Standard Standard HS-C hand chain hoist yenziwe ngezinto ezikumgangatho ophezulu wealloy kwaye inomsebenzi ogqwesileyo wokukhusela umthwalo. Xa ujongene nemeko apho umthwalo olinganisiweyo udlula umthwalo olinganisiweyo, i-hook ayiyi kuphuka ngokukhawuleza, kodwa iya kunika umqhubi isilumkiso esicacileyo sokhuseleko ngendlela yokuguqulwa kunye nokugoba, okuya kukhapha ukhuseleko lwemisebenzi ye-site.

V. Izilumkiso zokusebenzisa iihoists zamatsheyina ezandla
Ukuhlolwa kwangaphambili komsebenzi
Khangela ukuba i-hook, ikhonkco kunye ne-shaft zikhubazekile okanye zonakaliswe, ukuba izikhonkwane ekupheleni kwekhonkco ziqinile kwaye zithembekile, ingaba inxalenye yokuhambisa iguquguqukayo, ingaba inxalenye ye-brake ithembekile, kwaye ingaba ikhonkco lesandla liyi-slippage kunye nokuhla kwekhonkco.
Khangela ukuba ikhonkco lokuphakamisa linama-kinks, kwaye ukuba kunjalo, kufuneka lilungiswe ngaphambi kokusetyenziswa.
Iinkcukacha zokusebenza
Xa usebenzisa isixhasi setsheyini lesandla, qala utsale ikhonkco lesandla ngasemva kwaye ukhulule ikhonkco lokuliphakamisa ukuze libe nomgama owaneleyo wokuphakamisa, emva koko uliphakamise kancinci. Emva kokuba ikhonkco liqinisiwe, khangela ukuba kukho naziphi na izinto ezingaqhelekanga kwindawo nganye kunye nokuba ikhonkco ifanelekile. Kuphela emva kokuqinisekisa ukuba yinto eqhelekileyo unokuqhubeka nokusebenza.
Musa ukutsala umxokelelwane wesandla ngokuthobileyo okanye uqine kakhulu. Xa isetyenziswe kwindlela ethambekileyo okanye ethe tye, isikhokelo se-zipper kufuneka sihambelane nesalathiso se-sprocket ukuphepha i-jam yekhonkco kunye nokuhla kwekhonkco.
Inani le-zippers kufuneka limiselwe ngokwendlela yokuphakamisa i-hoist. Ukuba ayinakutsalwa, jonga ukuba igcwele kakhulu, ingaba idityanisiwe, nokuba i-hoist yonakalisiwe. Kunqatshelwe ngokungqongqo ukunyusa inani le-zippers ukutsala ngamandla.
Isondlo
Emva kokusetyenziswa, i-hoist kufuneka icocwe kwaye iqatywe ngegrisi echasene ne-rust, kwaye igcinwe kwindawo eyomileyo ukunqanda i-hand chain hoist ukuba i-rusa kunye nokuhlwa ngenxa yokufuma.
Ukuze kuqinisekiswe ukusetyenziswa ngokukhuselekileyo kwekhonkco lesandla, umntu ozinikeleyo kufuneka enze uhlolo rhoqo. Ukuhlolwa kunokwenziwa kanye ngonyaka, kwaye ukuba kukho iimeko ezingathandekiyo, kuya kuthatha ixesha elifutshane ukujonga. Khangela ukuba iikhomponenti zezixhobo zokuphakamisa zonakaliswe, zigugile, zonakalisiwe okanye zinomonakalo ongaqhelekanga. Zonke izixhobo zokhuseleko kufuneka zitshekishwe ngokucokisekileyo nangempumelelo. Iziqhoboshi kunye nemithwalo elinganisiweyo kufuneka ivavanyelwe ukunyuswa. Ukuba kuyimfuneko, i-hoist kufuneka ihlulwe ukujonga iindawo ezigugileyo.

VI. Isishwankathelo
Isixhobo sokukhusela i-overload ye-hand chain hoist sinokuqhawula ngexesha xa sithwele kakhulu ukukhusela izinto ezinzima ukuba ziphakanyiswe ngokuqhubekayo, ngaloo ndlela zikhusela ngokufanelekileyo izinto ezinzima ekuweni kunye nokuqinisekisa ukhuseleko lwabasebenzi kunye nezixhobo. Ekusetyenzisweni okwenyani, abaqhubi kufuneka balandele ngokuthe ngqo imilinganiselo yokusebenza, bajonge rhoqo kwaye bagcine i-hoist ye-hand chain, kwaye baqinisekise ukusebenza okuqhelekileyo kwesixhobo sokukhusela ukugqithiswa ukunciphisa ukwenzeka kweengozi.
