Gantry crane ibhiriji-mhando crane iro bhiriji rinotsigirwa panzira yepasi kuburikidza nevanobuda pamativi ese. Zvimiro, ine mast, trolley inoshanda sisitimu, trolley yekusimudza uye zvikamu zvemagetsi. Mamwe ma gantry cranes ane chete anobuda kune rimwe divi, uye rimwe divi rinotsigirwa pachivakwa chefekitori kana trestle, inonzi asemi-gantry crane. Iyo gantry crane inoumbwa neyekumusoro bhiriji furemu (inosanganisira huru danda uye yekupedzisira danda), outriggers, yakaderera danda uye zvimwe zvikamu. Kuti uwedzere huwandu hwekushanda kwecrane, danda guru rinogona kupfuudza kunze kwekubuda kune rimwe kana mativi ese maviri kuita cantilever. Trolley inosimudza ine boom inogona zvakare kushandiswa kuwedzera kiredhiti inoshanda renji kuburikidza nekudzika uye kutenderera kweboom.
1. Form classification
Gantry cranesinogona kuverengerwa zvichienderana nechimiro chegonhi remusuwo, chimiro chedanda guru, chimiro chedanda guru, uye chimiro chekushandisa.
a. Door frame frame
1. Full gantry crane: danda guru harina overhang, uye trolley inofamba mukati mehombe huru;
2. Semi-gantry crane: Vanobuda kunze vane misiyano yehurefu, iyo inogona kutariswa zvinoenderana nezvinodiwa zveinjiniya zvesaiti.
b. Cantilever gantry crane
1. Double cantilever gantry crane: Chimiro chechimiro chechimiro, kushushikana kwechimiro uye kushandiswa kunobudirira kwenzvimbo yepaiti inonzwisisika.
2. Single cantilever gantry crane: Iyi fomu yemaitiro inowanzosarudzwa nekuda kwezvirambidzo zvesaiti.
c. Main beam fomu
1.Single huru danda
Iyo imwechete huru girder gantry crane ine chimiro chakareruka, chiri nyore kugadzira uye kuisa, uye ine mashoma mashoma. Iyo huru girder kazhinji ndeye deflection bhokisi furemu chimiro. Kuenzaniswa nekaviri main girder gantry crane, kuomarara kwese hakuna kusimba. Nokudaro, iyi fomu inogona kushandiswa apo simba rekusimudza Q≤50t uye span S≤35m. Single girder gantry crane door makumbo anowanikwa muL-type uye C-type. Iyo L-mhando iri nyore kugadzira nekuisa, ine yakanaka kusagadzikana kusagadzikana, uye ine mashoma mashoma. Zvisinei, nzvimbo yekusimudza zvinhu kuti ipfuure nemakumbo idiki. Makumbo akaumbwa neC anogadzirwa muchimiro chakarerekera kana chakakombama kugadzira nzvimbo yakakura yelateral kuitira kuti zvinhu zvipfuure nemumakumbo zvakanaka.
2. Double main danda
Kaviri main girder gantry cranes ane simba rekutakura mutoro, mahombe akatambanudzwa, kugadzikana kwakanaka kwese, uye marudzi mazhinji. Nekudaro, zvichienzaniswa neamwechete main girder gantry cranes ane simba rekusimudza rakafanana, huremu hwavo hwakakura uye mutengo wakakwira. Zvinoenderana neakasiyana makuru danda zvimiro, inogona kukamurwa kuita maviri mafomu: bhokisi danda uye truss. Kazhinji, zvivakwa zvakaita sebhokisi zvinoshandiswa.
d. Main danda chimiro
1.Truss danda
Chimiro chechimiro chakashongedzwa nesimbi yekona kana I-beam ine zvakanakira mutengo wakaderera, uremu huremu uye mhepo yakanaka kuramba. Nekudaro, nekuda kwehuwandu hukuru hwewelding mapoinzi uye kukanganisa kweiyo truss pachayo, iyo truss danda inewo zvikanganiso senge hombe deflection, yakaderera kuomarara, kuderera kuvimbika, uye kudiwa kwekugara uchionekwa kwewelding mapoinzi. Inokodzera nzvimbo dzine pasi pekuchengetedza zvinodiwa uye diki yekusimudza simba.
2.Bhokisi danda
Mahwendefa esimbi anosungirirwa mubhokisi rebhokisi, iro rine maitiro ekuchengetedzwa kwepamusoro uye kuoma kwepamusoro. Kazhinji inoshandiswa kune hombe-tonnage uye Ultra-yakakura-tonnage gantry cranes. Sezvinoratidzwa pamufananidzo uri kurudyi, MGHz1200 ine simba rekusimudza rematani zana nemakumi maviri. Ndiyo yakakura gantry crane muChina. Iyo huru danda inotora chimiro chebhokisi girder. Mabhokisi matanda anewo zvakaipira kudhura kwakanyanya, huremu hunorema, uye kusamira zvakanaka kwemhepo.
3.Muzinga wehuchi
Kazhinji inonzi "isosceles triangle honeycomb beam", kumagumo kwedanda guru kune katatu, kune maburi ehuchi pa oblique webs kumativi ose maviri, uye kune zvinyorwa kumusoro nezasi. Mizinga yehuchi inotora hunhu hwematanda etruss uye matanda ebhokisi. Kuenzaniswa nematanda etruss, ane kuomarara kukuru, kutsauka kudiki, uye kuvimbika kwepamusoro. Nekudaro, nekuda kwekushandiswa kwesimbi plate welding, iyo self-uremu uye mutengo wakakwira zvishoma pane iwo wetruss matanda. Inokodzera masaiti kana danda masaiti anogara achishandiswa kana inorema kusimudza simba. Sezvo iyi danda rudzi chiri chigadzirwa chine patent, kune vashoma vanogadzira.
2. Fomu yekushandisa
1. Ordinary gantry crane
2.Hydropower station gantry crane
Inonyanya kushandiswa kusimudza, kuvhura nekuvhara masuwo, uye inogona kushandiswawo pakuisa mabasa. Iyo yekusimudza simba inosvika 80 kusvika 500 toni, iyo span idiki, 8 kusvika 16 metres, uye yekusimudza kumhanya yakaderera, 1 kusvika 5 metres / min. Kunyangwe rudzi urwu rwe crane isingawanzo kusimudzwa, basa racho rinorema zvakanyanya kana rangoshandiswa, saka nhanho yebasa inofanirwa kuwedzerwa zvakakodzera.
3. Shipbuilding gantry crane
Inoshandiswa kuunganidza hull pa slipway, matrolley maviri ekusimudza anogara aripo: imwe ine zvikorekedzo zviviri zvikuru, zvinomhanya panjanji iri kumusoro kwebhiriji; imwe yacho ine chirauro chikuru uye chiredzo chebetsero, pamucheto wezasi webhiriji. Mhanya panjanji kuti utenderere uye usimudze zvikamu zvakakura zvehull. Iyo yekusimudza simba inowanzoita zana kusvika ku1500 matani; kureba kunosvika 185 metres; iyo yekusimudza kumhanya ndeye 2 kusvika 15 metres / min, uye kune micro movement yekumhanya ye 0.1 kusvika 0.5 metres / min.
3. Mwero webasa
Gantry crane zvakare iri nhanho yekushanda A yegantry crane: inoratidza mashandiro eiyo crane maererano nemamiriro ekuremerwa uye kubatikana kushandiswa.
Kupatsanurwa kwematanho ebasa kunotsanangurwa nechikamu chekushandiswa kwecrane U uye mamiriro ekuremedza Q. Iwo akakamurwa kuita nhanho sere kubva kuA1 kuenda kuA8.
Chiyero chekushanda checrane, ndiko kuti, chiyero chekushanda chesimbi chimiro, chinotemerwa maererano nekusimudza michina uye yakakamurwa kuita mazinga A1-A8. Kana ichienzaniswa nemhando dzekushanda dze cranes dzakatsanangurwa muChina, inenge yakaenzana ne: A1-A4-chiedza; A5-A6- Medium; A7-inorema, A8-yakawedzera kurema.
