Chii chinonzi Steel Structure Crane Beam?
Crane simbi girders chikamu chakakosha chechero chirongwa chekuvaka chinoda kushandiswa kwemacranes.Iri danda rakanyatsogadzirirwa kupa rutsigiro uye kugadzikana kune crane kana uchisimudza nekufambisa mitoro inorema.Simba rayo uye kusimba kunoita kuti ive sarudzo yepamusoro muindasitiri yekuvaka.
Izwi rekuti "simbi dhizaini crane beam" rinoreva nhengo yakachinjika yakarongeka inotenderera maviri kana anopfuura mapoinzi ekutsigira.Inoshanda segadziriro yekuti crane ishande pairi uye inopa yakagadzikana chikuva chekusimudza uye kufamba kwezvinhu.Aya matanda anowanzo kugadzirwa kubva kusimbi nekuda kwesimba rayo-kusvika-uremu reshiyo, iyo inobvumira kuvakwa kwemahombe uye anobudirira crane masisitimu.
Chimiro chesimbi chimiro crane beam:
1.Box girder design
Imwe yemhando dzakajairika dzesimbi structural crane girders ndeye bhokisi girder dhizaini.Iyo dhizaini ine hollow rectangular chimiro chinopa yakanakisa simba uye mutoro wekutakura.Iyo yepamusoro uye pasi flanges yebhokisi girder yakabatanidzwa ne vertical webs kuti iite yakasimba uye yakagadzikana chimiro.Bhokisi girder madhizaini anowanzo kufarirwa nekuda kwekushanda kwawo mukupokana nekukotama uye torsional masimba, achivaita akakodzera mabasa ekusimudza anorema.
2.I-danda kugadzira
Imwe nzira yakakurumbira yesimbi crane girder ndeye I-beam dhizaini.I-matanda, anozivikanwawo sematanda epasi rose kana H-matanda, akafanana netsamba "Ini" muchikamu-chikamu.Iyo yepamusoro uye yakaderera flanges yeI-beam yakabatanidzwa ne vertical webs kuti iite yakasimba uye yakagadzikana chimiro.Iyo I-beam dhizaini inozivikanwa neiyo yakakwirira simba-kusvika-huremu reshiyo, ichiita kuti ive yakakodzera kune maapplication uko kudzikisa uremu kuri pamberi.Inowanzo shandiswa munzvimbo dzine nzvimbo shoma kana kureba zvirambidzo sezvo ichibvumira huwandu hwekuremedza huwandu mune compact dhizaini.
3.Truss girders
Pamusoro pebhokisi girder uye I-beam dhizaini, simbi crane girders inouya mune mamwe maitiro senge truss girders uye truss girders.Truss matanda ane akawanda akabatana mativi matatu, achipa kuchinjika uye kugona mukugovera mitoro.Lattice matanda, kune rumwe rutivi, akagadzirwa ane akavhurika webs ane diagonal nhengo, achibvumira kureruka uremu uye inodhura-inoshanda chimiro.
Kana dhizaini yapera, kugadzirwa uye kuiswa kwesimbi chimiro crane danda kunogona kutanga.Nzira yekugadzira inosanganisira kucheka uye kuumba zvikamu zvesimbi maererano nemaitiro ekugadzirisa.Welding matekiniki anowanzo shandiswa kubatanidza zvikamu zvakasiyana pamwechete, kuve nechokwadi chechimiro chechimiro chedanda.
Panguva yekumisikidza, iyo simbi dhizaini crane danda yakabatana zvakachengeteka kune nzvimbo dzekutsigira, kazhinji uchishandisa mabhaudhi kana welding.Kurongeka kwakaringana uye kuyera kwakakosha kuitira kuti danda rishande nemazvo uye rinogona kutsigira mafambiro ecrane.Pamusoro pezvo, kusungirira kwakaringana nekusimbisa kunogona kudikanwa kuti uwedzere kugadzikana kwese uye kutakura mutoro wedanda.
Kuchengeta simbi chimiro crane danda iri nyore kana ichienzaniswa nemamwe marudzi emidziyo yekuvaka.Kuongororwa nguva dzose kunokurudzirwa kutarisa chero zviratidzo zvekupfeka, kukuvara, kana deformation yemaitiro.Kana paine nyaya dzikaonekwa, dzinofanirwa kugadziriswa nekukasira kudzivirira kuwedzera kushatisa uye kuve nechokwadi chekushanda kwakachengeteka kwecrane.
