I-Gantry Crane iyi-crane yebhuloho-uhlobo lwe-crane ebhuloho lakhe elisekelwa emhlabathini ithrekhi ngokusebenzisa ama-opurkger ezinhlangothini zombili. Ngokuhlelekile, kuqukethe i-mast, inqubo yokusebenza kwe-trolley, i-trolley ephakamisayo nezingxenye zikagesi. Eminye imichilo ye-gantry inama-topligger kuphela ohlangothini olulodwa, futhi kolunye uhlangothi lusekelwa esakhiweni sefekthri noma i-trestle, ebizwa ngokuthiSemi-Gantry Crane. I-gantry crane yakhiwa ngohlaka lwebhuloho eliphezulu (kufaka phakathi ugongolo oluphambili bese uqeda ugongolo), ama-opurger, ugongolo oluphansi nezinye izingxenye. Ukuze wandise ibanga lokusebenza kwe-crane, ugongolo oluphambili lunganweba ngale kokuphuma kwelinye noma zombili izinhlangothi ukwakha i-cantilever. I-trolley ephakamisayo ene-boom nayo ingasetshenziswa ukwandisa ibanga elisebenzayo le-crane ngokusebenzisa ukugibela nokujikeleza kwe-boom.
1. Ukuhlukaniswa kwefomu
Ama-gantry cranesIngahlukaniswa ngokuya ngesakhiwo sohlaka lomnyango, uhlobo logongolo oluphambili, ukwakheka komshini omkhulu, kanye nohlobo lokusebenzisa.
a. Isakhiwo sohlaka lomnyango
1. I-Gantry Crane ephelele: Ugongolo oluphambili alunayo i-overhang, kanye nokuhamba kweTrolley ngaphakathi kwesikhala esikhulu;
2. Semi-Gantry Crane: Ama-Outrigger anokuphakama umehluko, ongazimisela ngokuya ngezidingo zobunjiniyela bomphakathi zesayithi.
b. Cantilever gantry crane
1. Double Cantilever Gantry Crane: Ifomu elijwayelekile kakhulu lesakhiwo, ukucindezelwa kwesakhiwo nokusetshenziswa okusebenzayo kwendawo yendawo kunengqondo.
2. Single Cantilever Gantry Crane: Leli fomu lesakhiwo livame ikhethwe ngenxa yemikhawulo yesayithi.
c. Ifomu Elikhulu Beam
1.Single Main Beam
I-girter eyodwa ye-girder Crane inesakhiwo esilula, kulula ukuyenza futhi ifake, futhi inenqwaba encane. I-girder eyinhloko kakhulu yisakhiwo sohlaka lwe-deflection. Uma kuqhathaniswa ne-girter eyingqayizivele ye-girter gane, ukuqina okuphelele kubuthakathaka. Ngakho-ke, leli fomu lingasetshenziswa lapho umthamo wokuphakamisa Q≤50T kanye ne-span s≤35m. Imilenze eminyango ye-gery gane ye-gantry crane iyatholakala ku-l-hlobo nohlobo lwe-C. Uhlobo lwe-L kulula ukwenza futhi lufake, lunokumelana kahle nokucindezela, futhi lunenqwaba encane. Kodwa-ke, isikhala sokuphakamisa izimpahla ukuze sidlule emilenzeni encane. Imilenze ekhethwe yi-C yenziwa ngesimo esithambekele noma esigobile ukudala isikhala esikhulu samuva ukuze izimpahla zidlule emilenzeni kahle.
2. Ugongolo oluphambili oluyinhloko
I-Double Gind Order Cranes inomthamo oqinile wokuthwala umthwalo, izikhala ezinkulu, ukuqina okuhle, nezinhlobo eziningi. Kodwa-ke, uma kuqhathaniswa nama-cranes asemqoka e-girter gantry anomthamo ofanayo wokuphakamisa, isisindo sabo sikhulu futhi izindleko ziphakeme. Ngokusho kwezakhiwo ezihlukile ze-Beam Main, zingahlukaniswa ngezindlela ezimbili: Ibhokisi logongolo kanye neTruss. Ngokuvamile, izakhiwo ezakhiwe ngamabhokisi ziyasetshenziswa.
d. Isakhiwo esikhulu se-Beam
I-1.Truss Beam
Ifomu lesakhiwo elifakwe insimbi ye-angle noma i-weam linezinzuzo zezindleko eziphansi, isisindo esikhanyayo kanye nokumelana nomoya okuhle. Kodwa-ke, ngenxa yenani elikhulu lamaphoyinti we-welding kanye ne-truss ngokwalo, i-truss beam nayo inamaphutha anjengokwephulwa okukhulu, ukuqina okuphansi, kanye nesidingo sokutholwa njalo kwamaphoyinti we-welding. Ilungele amasayithi anezidingo eziphansi zokuphepha namandla amancane wokuphakamisa.
I-2.Box Beam
Amapuleti ensimbi afakwa esakhiweni sebhokisi, elinezici zokuphepha okuphezulu nokuqina okuphezulu. Ngokuvamile esetshenziselwa ama-tonnage amakhulu nama-tonnage-tonnage gantry. Njengoba kukhonjisiwe esithombeni ngakwesokudla, i-MGHZ1200 inesilinganiso sokuphakamisa amathani ayi-1,200. Yi-ganery crane enkulu kunazo zonke eChina. Umfutho omkhulu wamukele i-box girder isakhiwo. Ama-Box Beams abuye abe nobubi bezindleko eziphezulu, isisindo esindayo, kanye nokumelana komoya ompofu.
3.HoneyComb Beam
Ngokuvamile okubizwa ngokuthi "okungunxantathu we-isOsces unxantathu wezinyosi", ubuso bokuphela bogongolo oluyinhloko, kunezimbobo zezinyosi zezinyosi kuma-webs oblique nhlangothi zombili, futhi kukhona imisindo ezingxenyeni ezingaphezulu nangaphansi. Imishayo yezinyosi yezinyosi ithola izici ze-Truss Beams kanye nemishayo yebhokisi. Uma kuqhathaniswa nemishayo ye-truss, banokuqina okukhulu, ukunqotshwa okuncane, kanye nokwethenjwa okuphezulu. Kodwa-ke, ngenxa yokusetshenziswa kwe-welding yensimbi yensimbi, okusindayo nezindleko kuphakeme kancane kunalokho kwe-truss beams. Ilungele amasayithi noma amasayithi we-beam asetshenziswa njalo noma amandla ashukumisayo anamandla. Njengoba lolu hlobo lwe-beam luwumkhiqizo onamalungelo obunikazi, kunabakhiqizi abambalwa.
2. Ifomu Lokusetshenziswa
1. I-gantry ejwayelekile ye-gantry
Isikhungo se-Gantry Crane
Isetshenziselwa ikakhulukazi ukuphakamisa, ukuvula nokuvala amasango, futhi nakho kungasetshenziselwa imisebenzi yokufaka. Amandla wokuphakamisa afinyelela amathani angama-80 kuye kwangama-500, i-span incane, amamitha ayi-8 kuye kwayi-16, futhi ijubane lokuphakamisa liphansi, 1 kuya ku-5 metres / min. Yize lolu hlobo lwe-crane lungaphakanyiswa kaningi, umsebenzi unzima kakhulu uma selusetshenziswa, ngakho-ke izinga lomsebenzi likhuphuke ngokufanele.
I-3. I-Gantry Crane yakudala
Kusetshenziselwe ukuhlanganisa i-hall e-slipway, ama-trolleys amabili aphakamisayo ahlala etholakala: umuntu unezingwegwe ezimbili eziphambili, egijima ethafeni elise-flange elingaphezulu lebhuloho; Enye ine-hook enkulu kanye ne-hook ezayo, e-flange ephansi yebhuloho. Gijimani ngojantshi ukuze ugobe futhi uphakamise izingxenye ezinkulu ze-hull. Umthamo wokuphakamisa ngokuvamile amathani ayi-100 kuye kwayi-1500; I-span ifinyelela kumamitha ayi-185; Ijubane lokuphakamisa lingamamitha amabili kuya kwayi-15 / imizuzu, futhi kunejubane elikhulu lokuhamba elingu-0,1 kuya ku-0.5 metres / min.
3. Izinga lomsebenzi
I-Gantry Crane futhi i-Level esebenza i-Gantry Crane: Ibonisa izici zokusebenza kwe-crane ngokwesimo somthwalo kanye nokusetshenziswa okumatasa.
Ukwahlukaniswa kwamazinga omsebenzi kunqunywa ngezinga lokusetshenziswa kwe-crane kanye nesimo sokulayisha Q. Zihlukaniswe ngamazinga ayisishiyagalombili ukusuka ku-A1 kuye ku-A8.
Izinga elisebenzayo le-crane, okungukuthi, izinga elisebenzayo lesakhiwo sensimbi, linqunywa ngokuya ngomshini wokuphakamisa futhi lihlukaniswe ngamazinga A1-A8. Uma kuqhathaniswa nezinhlobo ezisebenzayo ze-Cranes ezichazwe eChina, zilingana kakhulu ne: A1-A4-Light; A5-A6-ISINTY; I-A7-Heavy, A8-Extendand Export.
