Kukho iindlela ezintathu zokuhlola eziqhelekileyo ezisetyenziswayoi-lever hoist: ukuhlolwa okubonakalayo, ukuhlolwa kovavanyo, kunye nokuhlolwa kokusebenza kwe-braking.Ngezantsi siza kuchaza ezi ndlela zokuhlola ngokweenkcukacha nganye nganye:
1. Ukuhlolwa okubonakalayo
1. Zonke iindawo zei-ratchet lever hoistkufuneka zenziwe kakuhle, kwaye kungabikho iziphene ezifana nezibazi kunye burrs ezichaphazela ukubonakala Zhilian.
2. Imeko yekhonkco yokuphakamisa kufuneka ichithwe phantsi kwezi meko zilandelayo:
A. Ukonakala: Umphezulu wetyathanga udleke ngokumila kumngxuma okanye itshiphu ixotyulwe.
B. Ukugqithisa okugqithisileyo kwekhonkco kudlula i-10% ye-diameter ye-nominal.
C. Ukuguqulwa, iintanda kunye nomonakalo wangaphandle;.
D. Inowuthi iba ngaphezulu kwe-3%.
3. Ubume be hook, le miqathango ilandelayo kufuneka ichithwe:
A. Iphini lokhuseleko lehuku likhubazekile okanye lilahlekile.
B. Umjikelo wehuku uyarusa kwaye awukwazi ukujikeleza ngokukhululekileyo (360 ° ukujikeleza)
C. I-hook igugile kakhulu (ngaphezu kwe-10%) kwaye i-hook ikhubazekile (ngaphezu kwe-15% ngobukhulu), i-torsion (ngaphezu kwe-10 °), ii-cracks, i-angles acute, i-corrosion, kunye ne-warpage.
D. Imanual lever hoistkufuneka ixhotyiswe ngesixhobo esifanelekileyo sokuthintela ikhonkco ukuncedisa ekubandakanyekeni okuchanekileyo kwekhonkco kunye ne-sprocket, kwaye xa i-lever hoist ibekwe kwaye igxininiswe ngokuthanda, qinisekisa ukuba ikhonkco alikwazi ukuwa kwi-groove ring groove.
2. Indlela yokuvavanya
1. Uvavanyo lwesenzo sokungabikho komthwalo: Kwimeko yokungabikho komthwalo wei-lever hoist ephathekayo, tsala umqheba kwaye uguqule uzipho olubuyisela umva ukwenza ihuku iphakame kwaye iwe kube kanye.Indlela nganye kufuneka isebenze ngokuguquguqukayo, kwaye akufuneki kubekho jamming okanye ukuqina.Khipha isixhobo se-clutch kwaye utsale ikhonkco ngesandla, ekufuneka kube lula kunye nokuguquguquka.
2. Uvavanyo lomthwalo weDynamic: Ngokomthwalo wovavanyo lwamaxesha e-1.25, kwaye ngokobude obuchaziweyo bokuphakamisa uvavanyo, luphakanyiswa kwaye luthotywe kanye.Kwangaxeshanye, ezi mfuno zilandelayo kufuneka zifezekiswe.Ukuya
A. Ukuphakamisa ikhonkco kunye ne-sprocket, inqanawa yokuhamba ngenqanawa, iziphu yesandla kunye ne-hand sprocket mesh kakuhle;
B. Ukuhanjiswa kwegiya kufuneka kuzinzile kwaye kungabi nezinto ezingaqhelekanga.
C. I-torsion of the chain of lifting chain ngexesha lokunyuswa kunye nokuhla;
D. Isibambo sihamba kakuhle, kwaye i-lever force ayinalo utshintsho olukhulu;
E. Isenzo sokuqhokra sithembekile.
3. Uvavanyo lokusebenza lweBraking
Layisha umthwalo ngokuhambelana novavanyo olumiselweyo, kwaye uvavanye ngokulandelelana ngamaxesha amathathu.Umthwalo wokuqala wokuvavanya amaxesha angama-0.25, okwesibini ixesha eli-1, kwaye okwesithathu ngamaxesha angama-1.25.Ngethuba lovavanyo, umthwalo kufuneka unyuswe nge-300mm, kwaye ke umthwalo kufuneka uncitshiswe ngendlela ye-manual ukuya ekuphakameni kwe-sprocket yokuphakamisa, kwaye emva koko ume i-1h, izinto ezinzima akufanele ziwele ngokwemvelo.
