Kunzwisisa kurongeka kwegantry cranes kunobatsira pakusarudza nekutenga cranes. Mhando dzakasiyana dze cranes dzinewo dzakasiyana siyana. Pazasi, chinyorwa ichi chinozivisa maitiro emhando dzakasiyana dzegantry cranes zvakadzama kuti vatengi vashandise sereferensi pakusarudza kutenga crane.
Zvinoenderana nechimiro chechimiro checrane frame
Zvinoenderana nechimiro chechimiro chemusuwo, inogona kukamurwa kuita gantry crane uye cantilever gantry crane.
Gantry craneszvakakamurwa kuva:
1. Yakazara gantry crane: danda guru harina overhang, uye trolley inofamba mukati mehombe huru.
2. Semi-gantry crane: Zvinoenderana nenzvimbo yekuvaka yevagari zvinodiwa, kureba kwevanobuda kunosiyana.
Cantilever gantry cranes yakakamurwa kuita:
1. Kaviri cantilever gantry crane: imwe yeakajairika mafomu ekugadzirisa, kushushikana kwayo kwemaitiro uye kushandiswa kwakanaka kwenzvimbo yesaiti kunonzwisisika.
2. Single cantilever gantry crane: Nekuda kwezvirambidzo zvesaiti, chimiro ichi chinowanzo kusarudzwa.
Kurongeka zvinoenderana nechimiro uye mhando yedanda guru re gantry crane:
1. Yakazara kupatsanurwa kweimwe main girder gantry cranes
Iyo single-girder gantry crane ine chimiro chakareruka, iri nyore kugadzira nekuisa, uye ine mashoma mashoma. Mazhinji ematanda ayo makuru akarerekera njanji bhokisi furemu zvimiro. Kuenzaniswa nedouble-girder gantry crane, kuomarara kwese hakuna kusimba. Naizvozvo, kana kusimudza uremu Q≤50 matani, span S≤35m.
Single girder gantry cranemakumbo emusuwo anowanikwa muL-mhando uye C-mhando. Iyo L-yakaumbwa modhi iri nyore kuisa, ine simba rakanaka rekudzivirira, uye ine mashoma mashoma, asi nzvimbo yekusimudza zvinhu kuburikidza nemakumbo idiki. Makumbo akaita seC akarereka kana kukotama kuti ape nzvimbo yakakura yakachinjika kuti zvinhu zvifambe zvakanaka mumakumbo.
2. Complete classification of double main girder gantry cranes
Double-girder gantry cranesvane simba rekutakura rakasimba, mapani makuru, kugadzikana kwakanaka kwese, uye mhando dzakawanda, asi huwandu hwavo hwakakura kupfuura single-girder gantry cranes ine simba rekusimudza rakafanana, uye mutengo wakakwira zvakare.
Zvinoenderana neakasiyana makuru danda zvimiro, inogona kukamurwa kuita maviri mafomu: bhokisi danda uye truss. Parizvino, zvivakwa zvemhando yebhokisi zvinowanzoshandiswa.
Classification inoenderana neiyo huru danda chimiro chegantry crane:
1. Truss girder gantry crane
Iyo welded chimiro chekona simbi kana I-beam ine zvakanakira mutengo wakaderera, uremu huremu uye yakanaka mhepo kuramba.
Nekudaro, nekuda kwenhamba huru yewelding point, iyo truss pachayo ine hurema. Iyo truss danda zvakare ine zvikanganiso senge yakakura kutsauka, yakaderera kuomarara, yakaderera kuvimbika, uye kudiwa kwekugara uchionekwa kwewelding mapoinzi. Inokodzera nzvimbo dzine yakaderera kuchengetedzwa zvinodiwa uye kusimudza madiki uremu.
2. Bhokisi girder gantry crane
Mahwendefa esimbi anosungirirwa mubhokisi rakagadzirwa nebhokisi, rine maitiro ekuchengetedzwa kwepamusoro uye kuoma kwepamusoro. Kazhinji inoshandiswa kune yakakura tonnage uye hombe tonnage gantry cranes. Iyo huru danda inotora bhokisi danda chimiro. Mabhokisi matanda anewo zvakaipira kudhura kwakanyanya, huremu hwakafa, uye kusamira zvakanaka kwemhepo.
3. Muzinga wehuchi danda gantry crane
Inowanzonzi "isosceles triangle honeycomb beam", kumagumo kwedanda guru kune katatu, uye kune maburi ehuchi kumativi ose egumbo re oblique, kumusoro uye nechepasi chords. Maserura matanda anotora maitiro ematanda etruss uye matanda ebhokisi, uye ane kuomarara kukuru, kuderera kudiki uye kuvimbika kwepamusoro kupfuura matanda etruss.
Nekudaro, nekuda kwekuiswa kwesimbi mahwendefa, iyo yekuzvitakura uye mutengo wakakwira zvishoma pane iwo ematanda etruss. Inokodzera kushandiswa kazhinji kana nzvimbo dzinorema dzekusimudza kana nzvimbo dzedanda. Nekuti rudzi urwu rwedanda chigadzirwa chemuridzi, kune vashoma vanogadzira.
