Ukusiza umakhi: isisindo kanye nosayizi I-ugongolo

Omunye ezichumayo metal kuyinto usayizi cross-Sectional incwadi double Emaceleni T. I-ugongolo ugongolo-like incike injongo yawo nokuthi zokhahlamba kusuka ngamamitha amane kuya 12.

Beam kabili tee: Izinhlobo

Izinhlobo amaphrofayli leyabantu abavamile futhi ekhethekile yakhelwe ukusebenza ngaphansi kwezimo ezithile (i monorails kudivayisi ukuqinisa shaft). Kuye ubude iphrofayli kungaba ntathu, amaningi ntathu, volumetric noma eziningi okuseleyo (5% batch isisindo), kanye off-gage. Direct isinqumo mina-ugongolo sifana ibanga kusuka onqenqemeni eyodwa elingaphandle nezinye eshalofini.

I-imishayo, kuncike zinhlobo abe kokungafani okukhulu ngosayizi. Ngokwesibonelo, ukushuba we eshalofini kuyinto variable, ngoba kuhlobene ezakheke (ubuso enalokho kuthambekela noma parallel). Futhi, mina-imishayo zihlukaniswa impahla zenziwa kuyiphi, ngoba kuthinta ukusetshenziswa kwabo ezindaweni ezihlukahlukene (of okuhlinza ekhethekile, carbon noma ongaphakeme ingxubevange steel, kukhona eceleni ashisayo iphuma girders steel).

Amazinga mina-imishayo

Kukhona amazinga eziningana esamukelekile ukuthi ubunye ubukhulu mina-ugongolo kuye indlela ukwakhiwa yayo kanye nokusetshenziswa. Ngokwesibonelo, ngo-steel ashisayo iphuma mina-ngemishayo ejwayelekile gauge ngabaqaphi oluqanjwe nemingcele ezinkulu - izilinganiso langempela esigabeni cross, inani 1 m inkomba amagugu of imithwalo esiphezulu ku-eksisi.

Ngu kweqa ngokunemba ugongolo ukuhlukanisa evamile (B esinelebuli) noma ukunemba okuphezulu (esinelebuli B).

amazinga athile elawulwa Ubukhulu uhlanganise mina-imishayo, lapho emashalofini ubhekene okufanayo, steel ashisayo iphuma, steel ekhethekile, nezinye izinhlobo ezikhethekile mina-ngemishayo mina-imishayo akhiqizwa Abenzi Ukucaciswa.

Ngo ngayinye mina-ugongolo ekhona ukulawula izipoki usayizi ecacisiwe (ukuphakama kwalo, ukujiya ububanzi isilinganiso flange, udonga ukujiya, le radii ka ugobile kwangaphakathi kanye emashalofini), nenqwaba imitha komugqa (kg) futhi inani amamitha tonne I-imishayo ngayinye.

izidingo GOST kuya mina-ugongolo 36

Ngokwesibonelo, sinesithakazelo kwesikwenzayo kabili T-ugongolo osayizi lapho izivakashi 8239-89 bazimisele. Imidwebo lezi amaphrofayli kuvame enikeziwe ejwayelekile futhi baphathe ulwazi oluningiliziwe isizinda, eyakhelwe Ubukhulu weJiyomethri ugongolo. Nazo ngokufanayo, sihambisana nezici zabo ezingokomzimba sephrofayela, kubalulekile uhlelo lwayo lokusebenza.

Izinga ebekiwe imingcele isici lolu hlobo sephrofayela, okuyizinto ejwayelekile kokubili abakhiqizi namakhasimende. Ngakho, mina-ngemishayo 36. Ubukhulu: ukuphakama - cm 36, ububanzi emashalofini - 14.5 cm, udonga ukujiya - 0,75 cm, ukushuba isilinganiso eshalofini - 12.3 mm, lapho le ngxenye engaphakathi ukuqoqa engaba kufanele kube hhayi ningi than 1.4 cm, emashalofini ukuqoqa - 0.6 cm.

Uhlobo Special M-imishayo asetshenziswa wokuqondisa Cranes phezulu futhi ugibelisa, kusukela ukushuba emashalofini ziye anda eqhathaniswa ezivamile.

Futhi bona zezikhombo ezisezingeni eliphezulu amatafula, kungaba ukwazi ngokunembile isisindo ngamunye imitha (gravity ethize) I-ugongolo 36, okuyinto njalo kuyafana futhi kufana 48,6 amakhilogramu.
