Izintambo zokukhuphuka zingahlukaniswa zibe izintambo eziguquguqukayo kanye nezintambo ezimile.Intambo eguquguqukayo ine-ductility enhle ukuze kuthi uma kunesenzakalo sokuwa, intambo inganwetshwa ngokwezinga elithile ukuze kuncishiswe umonakalo odalwe ukuwa ngokushesha komqwali.
Kukhona ukusetshenziswa okuthathu kwentambo eguqukayo: intambo eyodwa, intambo ewuhhafu, nentambo ekabili.Izintambo ezihambisana nokusetshenziswa okuhlukene zihlukile.Intambo eyodwa iyona esetshenziswa kakhulu ngoba ukusetshenziswa kulula futhi kulula ukuyisebenzisa;Intambo enguhhafu, eyaziwa nangokuthi izintambo ezimbili, isebenzisa izintambo ezimbili ukuze ziboshelwe endaweni yokuqala yokuvikela ngesikhathi esisodwa lapho ukhuphuka, bese lezi zintambo ezimbili ziboshelwa ezindaweni ezihlukene zokuvikela ukuze isiqondiso sentambo silungiswe ngobuhlakani futhi ukungqubuzana kwentambo kungancishiswa, kodwa futhi kwandiswe ukuphepha njengoba kunezintambo ezimbili zokuvikela umqwali.Nokho, akuvamile ukusetshenziswa ekugibeleni izintaba kwangempela, ngoba indlela yokusebenza yalolu hlobo lwentambo iyinkimbinkimbi, futhi abaqwali abaningi basebenzisa indlela yesihlilingi nokulenga ngokushesha, okungase futhi kulungise kangcono isiqondiso sentambo eyodwa;
Intambo ekabili iwukuhlanganisa izintambo ezimbili ezizacile zibe yinye, ukuze kuvinjwe ingozi yokusikwa nokuwa kwentambo.Ngokuvamile, izintambo ezimbili zohlobo olufanayo, imodeli, kanye nenqwaba zisetshenziselwa ukukhuphuka ngezintambo;Izintambo ezinobubanzi obukhudlwana zinamandla okuthwala angcono, ukumelana nemihuzuko, nokuqina, kodwa futhi zisinda.Ngokukhuphuka ngentambo eyodwa, izintambo ezinobubanzi obungu-10.5-11mm zifanele imisebenzi edinga ukumelana nokugqokwa okuphezulu, njengokukhuphuka izindonga zamadwala amakhulu, ukwakha ama-glacier formation, kanye nokuhlenga, ngokuvamile ku-70-80 g/m.9.5-10.5mm uwugqinsi olumaphakathi olusebenza kahle kakhulu, ngokuvamile luyi-60-70 g/m.Intambo engu-9-9.5mm ifanele ukugibela okunesisindo esincane noma ukugibela isivinini, ngokuvamile ku-50-60 g/m.Ububanzi bentambo esetshenziselwa ukukhuphuka ngentambo eyingxenye ngu-8-9mm, ngokuvamile kuphela 40-50 g/m.Ububanzi bentambo esetshenziselwa ukukhuphuka izintambo cishe bungu-8mm, ngokuvamile kuphela 30-45g/m.
Umthelela
I-Impact Force iyinkomba yokusebenza kwentambo, ewusizo kakhulu kubaqwali.Lapho inani liphansi, kuba ngcono ukusebenza kwentambo, okungavikela kangcono abaqwali.Ngokuvamile, amandla omthelela wentambo angaphansi kuka-10KN.
Indlela eqondile yokulinganisa amandla okushayisana yilena: intambo esetshenziswe okokuqala iwe uma inesisindo esingama-80kg (amakhilogremu) kanye nesici sokuwa (I-Fall Factor) ngu-2, kanye nokushuba okuphezulu okuthwala intambo.Phakathi kwazo, i-coefficient yokuwa = ibanga eliqondile lokuwa / ubude bezintambo obusebenzayo.
Ukwelashwa okungangeni manzi
Uma intambo isicwilisiwe, isisindo sizokhula, inani lokuwa lizokwehla, futhi intambo emanzi izoba yiqhwa emazingeni okushisa aphansi futhi ibe i-popsicle.Ngakho-ke, ekukhuphukeni okuphezulu, kuyadingeka kakhulu ukusebenzisa izintambo ezingangeni manzi ukuze ugibele iqhwa.
Inombolo enkulu yokuwa
Inani eliphezulu lokuwa liyinkomba yamandla entambo.Ngentambo eyodwa, inombolo enkulu yokuwa ibhekisela ku-coefficient yokuwa kwe-1.78, futhi isisindo sento ewayo singama-80 kg;Ngentambo yesigamu, isisindo sento ewayo singama-55 kg, kanti ezinye izimo zihlala zingashintshiwe.Ngokuvamile, inani eliphezulu lokuwa kwezintambo izikhathi ezingu-6-30.
Ukunwebeka
I-ductility yentambo ihlukaniswe yaba i-ductility eguquguqukayo kanye ne-ductility emile.I-dynamic ductility imele iphesenti lokunwetshwa kwentambo lapho intambo inesisindo esingama-80 kg kanti i-coefficient yokuwa ingu-2. Ukwandiswa okungaguquki kumelela iphesenti lokunwetshwa kwentambo uma ithwala isisindo esingu-80 kg lapho iphumule.
