Iibhloko zePulley: IsiXhobo esiNxulutywayo esiNcedayo kwiMechanical Advantage

Aibhloko yepuli, ekwabizwa ngokuba yi-pulley block, sisixhobo esilula kodwa esisebenzisekayo esiye sasetyenziswa iinkulungwane ukuphakamisa izinto ezinzima ngokulula. Iqulethe ipuli enye okanye ngaphezulu efakwe kwipuli okanye isakhelo ekugqithwa kuyo intambo okanye intambo. Iibhloko zePulley ziyinxalenye ebalulekileyo yeenkqubo ezininzi zoomatshini kwaye zisetyenziswa kumashishini ahlukeneyo aquka ukwakhiwa, ulwandle kunye nokuvelisa. Kweli nqaku, siza kuphonononga imisebenzi, iintlobo, kunye nokusetyenziswa kweeseti zepulley kunye nendima yazo ekuboneleleni ngoncedo lomatshini.

Umsebenzi we-pulley block
Umsebenzi oyintloko webhloko ye-pulley kukubonelela ngenzuzo yomatshini ngokunciphisa amandla afunekayo ukuphakamisa into enzima. Oku kufezwa ngokusabalalisa ubunzima bomthwalo kwiipuli ezininzi, ngaloo ndlela ukunciphisa amandla afunekayo ukuphakamisa umthwalo. Inzuzo yomatshini enikezelwa yibhloko ye-pulley inqunywe yinani leepuli kwinkqubo. Ngokomzekelo, i-pulley eyodwa esisigxina ayinayo inzuzo yomatshini, kanti inkqubo ene-pulleys ezininzi inokunciphisa kakhulu amandla afunekayo ukuphakamisa umthwalo.

Iintlobo zeebhloko zepuli
Kukho iintlobo ezininzi zeebhloko ze-pulley, nganye yenzelwe izicelo ezithile kunye neemfuno zomthwalo. Iindidi ze-pulley block eziqhelekileyo ziquka:

1. Ibhloko ye-pulley esisigxina: Olu hlobo lwe-pulley block lune-pulley egxininiswe kwisakhiwo esixhasayo njengesilingi okanye umqadi. Itshintsha isalathiso samandla asetyenziswe kumthwalo kodwa ayiboneleli nayiphi na inzuzo yomatshini.
2. Ukuhamba kwePulley Block: Kulo hlobo lwe-pulley block, i-pulley ifakwe kumthwalo ophakanyiswayo, okuvumela umsebenzisi ukuba asebenzise amandla aphantsi. Ibhloko ye-pulley ehambayo inika inzuzo yomatshini ngokusabalalisa ubunzima bomthwalo phezu kobude obubini bentambo.
3. Ibloko ye-pulley ehlanganisiweyo: Ibloko ye-pulley ehlanganisiweyo yenziwe ngeepuli ezininzi ezicwangciswe ngokudibeneyo kunye neepulleys ezisisigxina kunye neepulleys ezihambayo. Olu hlobo lwe-pulley block lunenzuzo ephezulu yomatshini kune-pulley eyodwa esisigxina okanye ehambayo.
4. I-Grab Pulley: I-pulley yokubamba luhlobo olukhethekileyo lwebhloko ye-pulley eyenzelwe ukusetyenziswa nge-winch okanye esinye isixhobo sokutsala. Inephaneli esecaleni ejingayo evumela ukuba intambo ifakwe ngaphandle kokuyithunga kwibhloko. Iibhloko zokuhlutha ziqhele ukusetyenziselwa ukutsalwa kunye nokubuyisela imisebenzi.

Ukusetyenziswa kwebhloko yepulley
Iibhloko zePulley zisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokukwazi ukubonelela ngeenzuzo zoomatshini kunye nokunceda ukuphakamisa izinto ezinzima. Ezinye izicelo eziqhelekileyo zeebhloko zepulley ziquka:

1. Umzi-mveliso wokwakha: Iibhloko ze-Pulley zisetyenziswa ngokubanzi kushishino lokwakha ukuphakamisa nokuhambisa izinto zokwakha ezinzima, ezifana neebhloko zekhonkrithi, imiqadi yentsimbi, izinto zokuphahla, njl njl. Ziyimfuneko ekuphakamiseni izixhobo kunye nezixhobo kwiindawo eziphakamileyo zokusebenza kunye noxinzelelo kunye nokukhusela. iintambo kunye neentambo.
2. Ishishini laseLwandle: Iibhloko ze-Pulley zisetyenzisiwe kwizicelo zaselwandle kangangamakhulu eminyaka, ngakumbi kwiinqanawa zokuhamba ngeenqanawa. Zisetyenziselwa ukunyusa kunye nokunciphisa iiseyile, ukunyusa imithwalo, kunye nokusebenzisa iinkqubo zokurhweba. Kwimisebenzi yala maxesha ekude nonxweme, iibhloko zepulley zisetyenziselwa ukwenza imisebenzi eyahlukahlukeneyo ebandakanya ukuxhoma, ukutsala kunye nokuphakamisa izixhobo ezinzima kwiinqanawa kunye namaqonga angaphesheya.
3. Ukwenziwa kunye nokugcinwa kweWarehousing: Iibhloko zepulley zisetyenziselwa ukuvelisa kunye neendawo zokugcina iimpahla ukuphakamisa kunye nokuhambisa oomatshini abanzima, izixhobo kunye nemathiriyeli. Zihlala zidityaniswe kwiinkqubo ze-crane eziphezulu kunye nezixhobo zokuphatha izinto ukuze ziququzelele ukuhamba kakuhle kwempahla ngaphakathi kwendawo.
4. Ngaphandle kwendlela kunye nokubuyisela: Kwimisebenzi engaphandle kwendlela kunye nokubuyisela, i-pulley block isetyenziswa ngokubambisana ne-winch ukuququzelela ukubuyiswa kwesithuthi, ukutsala kunye nokuhlola ngaphandle kwendlela. Iibhloko zokuhlutha, ngokukodwa, zibalulekile ekutshintsheni indlela ye-tow kunye nokwandisa umthamo wokutsala we-winch kwindawo enzima.

Izinto eziluncedo zoomatshini kwiibhloko zePulley
Enye yeenzuzo eziphambili zokusebenzisa iibhloko ze-pulley kukuba zibonelela ngenzuzo yomatshini evumela umsebenzisi ukuba aphakamise izinto ezinzima ngokulula. Inzuzo yomatshini webhloko ye-pulley ixhomekeke kwinani leentambo ezixhasa umthwalo kunye nenani leepuli kwinkqubo. Njengoko inani leentambo kunye neepulleys zanda, kunjalo ke inzuzo yomatshini, okwenza kube lula ukuphakamisa izinto ezinzima.

Inzuzo yomatshini ebonelelwa yibhloko ye-pulley ingabalwa ngokusebenzisa le fomula ilandelayo:

Inzuzo yomatshini = inani leentambo zokuxhasa umthwalo

Ngokomzekelo, ibhloko ye-pulley eneentambo ezimbini ezixhasa umthwalo iya kunika inzuzo yomatshini we-2, ngelixa i-pulley block enezintambo ezine ezixhasa umthwalo iya kunika inzuzo yomatshini we-4. Oku kuthetha ukuba amandla afunekayo ukuphakamisa umthwalo uyancitshiswa. ngento elingana nenzuzo yomatshini.

Ukongeza ekuboneleleni ngezibonelelo zoomatshini, iibhloko zepulley zinokuphinda zilawule amandla, zibavumele ukuba baphakamise imithwalo ngokuthe nkqo okanye ngokuthe tye, okanye baqondise kwakhona amandla ajikeleze imiqobo okanye iikona.

Iibhloko zePulleyzixhobo ezibalulekileyo ezibonelela ngeenzuzo zoomatshini kunye nokuququzelela ukuphakanyiswa kwezinto ezinzima kumashishini ahlukeneyo. Uyilo lwayo olulula kodwa olusebenzayo luyenza isebenziseke ngeendlela ezininzi kwaye iyimfuneko kuluhlu olubanzi lwezicelo, ukusuka kulwakhiwo kunye nemisebenzi yangaphandle konxweme ukuya kwimveliso kunye nokuphinda kusetyenziswe ngaphandle kwendlela. Ukuqonda imisebenzi, iintlobo, kunye nokusetyenziswa kweebhloko ze-pulley kubalulekile ukuzisebenzisa ngokufanelekileyo nangokukhuselekileyo kwiindawo ezahlukeneyo. Ingaba isetyenziswe kwi-pulley elula emiselweyo okanye njengenxalenye yenkqubo ye-pulley eyinkimbinkimbi, iibhloko ze-pulley zisadlala indima ebalulekileyo ekusebenzeni komatshini wanamhlanje.
