Izizathu zokungaphumeleli kwebrake yehand chain hoist

Iimbangela zokusilela kweziqhoboshi zeisandla chain hoistskunye neendlela zokusombulula ingxaki

Ukuba i-brake ye-hand chain hoist ayiphumelelanga xa idonsa ngokuqinileyo, inokuba ngenxa yomonakalo kwizinto eziphambili kwinkqubo yokuqhoqhobala. Inkqubo yokuqhobosha iquka iratchet, i-pawl, kunye nepleyiti yokukhuhlana. Imfezeko yala macandelo ibalulekile ekuqinisekiseni umsebenzi wokuqhobosha. Xa i-ratchet inamazinyo aphukileyo, ayikwazi ukudibanisa ngokufanelekileyo kunye ne-pawl, ibangela ukuba i-brake ingaphumeleli. Ngokufanayo, ukuba i-pawl spring ikhululekile, ayiyi kukwazi ukuqonda ivili le-ratchet ngexesha, eliya kuchaphazela ukunyathela. Ukongezelela, imeko yendawo yeplate ye-friction ayinakuhoywa. Ukuba ihlanjululwe ngamanzi okanye igrisi, i-friction yayo iya kuncitshiswa, ngaloo ndlela iyancipha i-braking effect. Izinto ezinjengokulayisha ngaphezulu kwekhonkco lekhonkco lesandla, ukuguqulwa kweqokobhe langaphandle okanye ukukrazuka kwepleyiti yokukhuhlana nako kunokukhokelela ekungaphumeleli kwebrake.

Ukusombulula ingxaki yokungaphumeleli kwe-brake ye-hand chain hoist, kufuneka uqale uqonde isizathu esithile sokungaphumeleli. Ngokomzekelo, ukuba ingxaki yi-ratchet erhabaxa ebangelwa ngamafutha, susa nje igrisi. Kwiidiski ze-friction okanye ezinye iziphene eziyinkimbinkimbi, kucetyiswa ukuba ufune uncedo kubasebenzi bezolondolozo kunye nokutshintsha iindawo ezonakalisiweyo xa kuyimfuneko. Nangona kunjalo, okubaluleke ngakumbi ngamanyathelo okuthintela. Ukusetyenziswa ngokufanelekileyo kunye nokugcinwa kwe-hand chain hoist kunokunciphisa kakhulu umngcipheko wokungaphumeleli kwe-brake.

Ukuze ugweme ukungaphumeleli kwe-brake ye-hand chain hoist, la manqaku alandelayo kufuneka aqatshelwe ngexesha lokusebenza. Okokuqala, ukulandela iinkqubo zokusebenza ezisemgangathweni kuyisitshixo sokuqinisekisa ukusebenza okuqhelekileyo kwe-chain hoist kunye nokwandisa ubomi bayo benkonzo. Okwesibini, kunqande ukulayisha ngaphezulu, kuba ukulayisha ngaphezulu kuya kwandisa ukungqubana phakathi kwepawl kunye nevili le-ratchet, kukhawulezise ukunxiba kwepleyiti ye-friction, kwaye ngaloo ndlela kuchaphazele ukusebenza kwe-braking. Ekugqibeleni, cwangcisa ixesha lokusetyenziswa kwekhonkco lesandla ngokufanelekileyo, kunqande ukusetyenziswa kwexesha elide, kwaye unike ixesha lokuphumla elifanelekileyo ukukhusela i-pawl spring kunye nezinye iindawo ukuba zikhululeke ngenxa yokudinwa ngokugqithiseleyo.
