Apulley block, iyo inonziwo pulley block, chishandiso chiri nyore asi chinogoneka chakashandiswa kwemazana emakore kusimudza zvinhu zvinorema zviri nyore. Inosanganisira imwe kana akawanda pulleys akaiswa papulley kana furemu iyo tambo kana tambo inopfuudzwa. Pulley mabhuroko chinhu chakakosha cheakawanda mechanicha masisitimu uye anoshandiswa mune akasiyana maindasitiri anosanganisira ekuvaka, emugungwa nekugadzira. Muchinyorwa chino, isu tichaongorora mabasa, mhando, uye mashandisiro emapulley seti nebasa rawo mukupa mabhenefiti emakina.
Basa re pulley block
Basa rekutanga repulley block ndeyekupa mukana wemuchina nekudzikisa simba rinodiwa kusimudza chinhu chinorema. Izvi zvinoitwa nekugovera huremu hwemutoro pamapulleys akawanda, nokudaro kuderedza simba rinodiwa kusimudza mutoro. Iyo mechanical advantage inopiwa ne pulley block inotarirwa nehuwandu hwemapulleys muhurongwa. Semuenzaniso, imwe chete yakagadziriswa pulley inopa hapana mechanical advantage, nepo hurongwa hune pulleys dzakawanda hunogona kuderedza zvakanyanya simba rinodiwa kusimudza mutoro.
Mhando dzepulley blocks
Kune akawanda marudzi emapulley blocks, rimwe nerimwe rakagadzirirwa chaiwo maapplication uye zvinorema zvinodiwa. Mhando dzakajairika dzepulley block dzinosanganisira:
- Fixed pulley block: Rudzi urwu rwepulley block ine pulley inomisikidzwa kune inotsigira chimiro senge sirin'i kana danda. Inoshandura kutungamira kwesimba rinoshandiswa kumutoro asi haipe chero mechanical advantage.
- Kufambisa Pulley Block: Murudzi urwu rwepulley block, pulley inosungirirwa pamutoro uri kusimudzwa, ichibvumira mushandisi kushandisa simba rekudzika pasi. Inofamba pulley block inopa mukana wemuchina nekugovera huremu hwemutoro pamusoro pehurefu huviri hwetambo.
- Composite pulley block: Iyo inosanganiswa pulley block inoumbwa nemapulley akawanda akarongwa musanganiswa neakagadziriswa pulleys uye anofambiswa pulleys. Iyi mhando yepulley block ine yakakwirira mechaniki mabhenefiti pane imwechete yakagadziriswa kana inofambiswa pulley.
- Grab Pulley: A grab pulley imhando yakakosha yepulley block yakagadzirirwa kushandiswa newinch kana imwe dhizaini yekudhonza. Iine hinged side panel inobvumira tambo kuti iiswe pasina kuipinza mublock. Snatch blocks anowanzo shandiswa kudhonza uye kudzoreredza mashandiro.
Kushandiswa kwepulley block
Pulley block anoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwekugona kwavo kupa mabhenefiti emakanika uye kubatsira kusimudza zvinhu zvinorema. Mamwe maapplication akajairika emapulley block anosanganisira:
- Indasitiri yekuvaka: Mabhuroki ePulley anoshandiswa zvakanyanya muindasitiri yekuvaka kusimudza uye kufambisa zvinhu zvinorema zvekuvakisa, senge makongiri mabhuroko, matanda esimbi, zvekufurira zvinhu, nezvimwe. Izvo zvakakosha pakusimudza midziyo uye zvinhu kunzvimbo dzakakwirira dzebasa uye kumanikidza uye kuchengetedza. tambo netambo.
- Maritime Indasitiri: Mabhuroki ePulley akashandiswa mukushandiswa kwemugungwa kwemazana emakore, kunyanya mungarava dzezvikepe. Iwo anoshandiswa kusimudza nekudzikisa maseiri, kusimudza mitoro, uye kushandisa masisitimu ekubira. Mumabasa emazuva ano ekumahombekombe, zvivharo zvepulley zvinoshandiswa kuita mabasa akasiyana siyana anosanganisira kukoira, kukweva nekusimudza midziyo inorema pazvikepe nemapuratifomu ekumahombekombe.
- Kugadzira uye Kuchengeta: Mabhuroki ePulley anoshandiswa mukugadzira uye nzvimbo dzekuchengetera zvinhu kusimudza nekufambisa michina inorema, zvishandiso uye zvinhu. Iwo anowanzo sanganiswa mupamusoro crane masisitimu uye zvigadzirwa zvekubata zvinhu kuti zvifambise kufamba kwakanaka kwezvinhu mukati menzvimbo.
- Kunze-mugwagwa uye kudzoreredza: Mukunze-mumugwagwa uye kudzoreredza mashandiro, iyo pulley block inoshandiswa pamwe chete newinch kufambisa kudzoreredza mota, kudhonza uye kunze kwemugwagwa kuongorora. Snatch blocks, kunyanya, yakakosha pakushandura kutungamira kweiyo tow uye kuwedzera kugona kwekudhonza kwewinch munzvimbo yakaoma.
Mechanical Advantages ePulley Blocks
Imwe yemabhenefiti makuru ekushandisa pulley blocks ndeyekuti ivo vanopa mechanic mukana unobvumira mushandisi kusimudza zvinorema zvinhu zviri nyore. Iyo mechanic advantage yepulley block inoenderana nehuwandu hwetambo dzinotsigira mutoro uye nhamba yemapulleys muhurongwa. Sezvo nhamba yetambo uye pulleys inowedzera, ndizvo zvinoitawo kushandiswa kwemichina, zvichiita kuti zvive nyore kusimudza zvinhu zvinorema.
Iyo mechaniki kubatsirwa inopihwa nepulley block inogona kuverengerwa uchishandisa inotevera formula:
Mechanical advantage = nhamba yetambo dzekutsigira mutoro
Semuenzaniso, pulley block ine tambo mbiri dzinotsigira mutoro ichapa mechanical kubatsirwa kwe2, nepo pulley block ine tambo ina dzinotsigira mutoro ichapa mechanical kubatsirwa kwe 4. Izvi zvinoreva kuti simba rinodiwa kusimudza mutoro rakaderedzwa. nechinhu chakaenzana ne mechanical benefit.
Pamusoro pekupa mabhenefiti emakanika, pulley blocks anogona kutungamira masimba, achivabvumira kusimudza mitoro yakatwasuka kana yakatwasuka, kana kudzoreredza masimba akatenderedza zvipingamupinyi kana makona.
Pulley blocksmaturusi akakosha anopa mabhenefiti emuchina uye kufambisa kusimudzwa kwezvinhu zvinorema mumaindasitiri akasiyana. Dhizaini yaro yakapfava asi inoshanda inoita kuti ive inogoneka uye yakakosha kune dzakasiyana siyana dzekushandisa, kubva pakuvaka uye kushanda kwekunze kwemahombekombe kusvika pakugadzira uye kunze kwenzira kudzokorodza. Kunzwisisa mashandiro, mhando, uye mashandisirwo emapulley blocks kwakakosha kuti uzvishandise nemazvo uye zvakachengeteka munzvimbo dzakasiyana. Ingave yakashandiswa mune yakapfava yakagadziriswa pulley kumisikidzwa kana sechikamu cheyakaomesesa komputa pulley system, pulley blocks achiri kuita basa rakakosha mukushanda kwemichina yemazuva ano.
