Iintambo zokunyuka zingahlulwa zibe ziintambo ezitshintshayo kunye neentambo ezingashukumiyo. Intambo etshintshayo ithambile kakuhle kangangokuba xa kukho ithuba lokuwa, intambo inokolulwa ukuya kwinqanaba elithile ukuze kuncitshiswe umonakalo obangelwa kukuwa ngokukhawuleza komkhweli.
Kukho iindlela ezintathu zokusebenzisa intambo eguquguqukayo: intambo enye, intambo yesiqingatha, kunye nentambo ephindwe kabini. Iintambo ezihambelana nokusetyenziswa okwahlukeneyo zahlukile. Intambo enye yeyona isetyenziswa kakhulu kuba ukusetyenziswa kulula kwaye kulula ukuyisebenzisa; Intambo yesiqingatha, eyaziwa ngokuba yintambo ephindwe kabini, isebenzisa iintambo ezimbini ukuze zibotshelelwe kwindawo yokuqala yokukhusela ngaxeshanye xa unyuka, kwaye emva koko iintambo ezimbini zibotshelelwe kwiindawo ezahlukeneyo zokukhusela ukuze ulwalathiso lwentambo luhlengahlengiswe ngobuchule kwaye ukungqubana kwintambo kuncitshiswe, kodwa kwandiswe ukhuseleko njengoko kukho iintambo ezimbini zokukhusela umntu onyukayo. Nangona kunjalo, ayisetyenziswa rhoqo ekunyukeni intaba, kuba indlela yokusebenza yolu hlobo lwentambo iyinkimbinkimbi, kwaye abaninzi abanyukayo basebenzisa indlela yokuslayida nokuxhoma ngokukhawuleza, enokuthi ilungise ngcono ulwalathiso lwentambo enye;
Intambo ephindwe kabini yenzelwe ukudibanisa iintambo ezimbini ezincinci zibe yinto enye, ukuze kuthintelwe ingozi yokuba intambo inqunyulwe ize iwe. Ngokubanzi, iintambo ezimbini zohlobo olufanayo, imodeli, kunye nebhetshi zisetyenziselwa ukunyuka intambo; Iintambo ezinobubanzi obukhulu zinamandla okuthwala, ukumelana nokukrweleka, kunye nokuqina, kodwa zikwanzima. Ekunyukeni ngentambo enye, iintambo ezinobubanzi obuyi-10.5-11mm zifanelekile kwimisebenzi efuna ukumelana nokuguguleka okuphezulu, njengokunyuka iindonga ezinkulu zamatye, ukwenza iifom zeqhwa, kunye nokusindisa, ngokubanzi kwi-70-80 g/m. I-9.5-10.5mm bubukhulu obuphakathi obufanelekileyo, ngokubanzi yi-60-70 g/m. Intambo eyi-9-9.5mm ifanelekile ekunyukeni okulula okanye ekunyukeni ngesantya, ngokubanzi yi-50-60 g/m. Ububanzi bentambo esetyenziselwa ukunyuka isiqingatha sentambo yi-8-9mm, ngokubanzi yi-40-50 g/m kuphela. Ububanzi bentambo esetyenziselwa ukunyuka intambo bumalunga ne-8mm, ngokubanzi yi-30-45g/m kuphela.
Impembelelo
Amandla okuchukumisa luphawu lokusebenza kwentambo yokucupha, nto leyo eluncedo kakhulu kwabakhwela intaba. Okukhona ixabiso liphantsi, kokukhona ukusebenza kwentambo yokucupha kungcono, nto leyo enokubakhusela ngcono abakhwela intaba. Ngokubanzi, amandla okuchukumisa entambo angaphantsi kwe-10KN.
Indlela ethile yokulinganisa amandla ombane yile: intambo esetyenzisiweyo okokuqala iyawa xa ithwala ubunzima obuyi-80kg (iikhilogram) kwaye i-fall factor (Factor Factor) yi-2, kwaye uxinzelelo oluphezulu oluthwalwa yintambo. Phakathi kwazo, i-fall coefficient = umgama othe nkqo wokuwa / ubude bentambo obusebenzayo.
Unyango olungangeni manzi
Nje ukuba intambo imanziswe, ubunzima buya kwanda, inani lokuwa liya kuncipha, kwaye intambo emanzi iya kubanda kumaqondo obushushu aphantsi ize ibe yi-popsicle. Ke ngoko, xa ukhwela kwindawo ephakamileyo, kuyimfuneko kakhulu ukusebenzisa iintambo ezingangeni manzi xa ukhwela umkhenkce.
Inani eliphezulu lokuwa
Inani eliphezulu lokuwa libonisa amandla entambo. Kwintambo enye, inani eliphezulu lokuwa libhekisa kwi-coefficient yokuwa eyi-1.78, kwaye ubunzima bento ewayo yi-80 kg; Kwintambo esiqingatha, ubunzima bento ewayo yi-55 kg, kwaye ezinye iimeko azitshintshi. Ngokubanzi, inani eliphezulu lokuwa kwentambo liphindwe ka-6-30.
Ukwandiswa
Ukuqina kwentambo kwahlulwe ngokwe-dynamic ductility kunye ne-static ductility. Ukuqina kwentambo kubonisa ipesenti yokwandiswa kwentambo xa intambo inobunzima obuyi-80 kg kwaye i-fall coefficient yi-2. Ukuqina kwentambo okuzinzileyo kubonisa ipesenti yokwandiswa kwentambo xa ithwala ubunzima obuyi-80 kg xa iphumle.
