Kreni ya Maxtech Portal Crane Yolemera Kwambiri ndi Yaikulu Yonyamula Zikepe yokhala ndi Truss Jib Design
Chidule cha Zamalonda
MAXTECH Portal Crane ndi crane yolemera yokwezedwa pa njanji yopangidwa kuti inyamule/kutsitsa katundu m'madoko, malo ofikira, ndi m'malo opangira sitima. Yokhala ndi chitsulo cholimba, crane iyi idapangidwa makamaka kuti igwire ntchito bwino m'malo omwe mphepo yamphamvu imawomba - chofunikira kwambiri pazinthu za m'mphepete mwa nyanja zomwe nthawi zambiri zimakumana ndi mphepo yamkuntho.
Zinthu Zofunika Kwambiri Zopangira
Chitsulo cha Metal Truss - Chopangidwa kuti chiteteze mphepo
Jib imagwiritsa ntchito kapangidwe ka lattice truss (mafelemu a triangular kapena quadrilateral ovekedwa kuchokera ku chitsulo chomangidwa), chomwe chimapereka:
1. Kapangidwe kopepuka — kudzilemera kochepa poyerekeza ndi mapangidwe a bokosi
2. Chiŵerengero champhamvu kwambiri pakati pa kulemera — zinthu zomwe zili mu ziwalo za chord ndi ma diagonal kuti zigawidwe bwino kwambiri
3. Kuchepa kwa mphamvu ya mphepo — mpweya umadutsa mu truss yotseguka, kuchepetsa mphamvu za mbali
4. Kuchepetsa ndalama zogwirira ntchito — zipangizo zomangira mphepo zomwe zimakhala ndi mphamvu zochepa zimafunika
5. Kukonza kosavuta — kapangidwe kotseguka kamalola kuyang'ana kowoneka bwino, kulowa mkati mwa chophimba, ndi ngalande zachilengedwe kuti zisawonongeke
Mu malo ogwirira ntchito zombo komwe ma crane nthawi zambiri amapitirira mamita 60, ma truss main girders amalemera 40% mpaka 55% yokha ya mapangidwe ofanana a box-girder. Kuchepetsa kulemera kumeneku kumatanthauza mwachindunji kuchepetsa katundu wamagudumu, kuchepetsa ndalama zoyendetsera njanji ndi maziko, komanso kusintha kuyenda kwa crane.
Njira Zinayi Zogwirira Ntchito
MAXTECH Portal Crane ili ndi njira zinayi zazikulu zomwe zimagwira ntchito mogwirizana kuti zitheke kugwira ntchito mosinthasintha m'mbali mwa doko:
| Njira | Ntchito |
|---|---|
| Njira Yokwezera | Kukweza ndi kutsitsa katundu moyimirira — gawo lalikulu la mphamvu ya crane |
| Njira Yopukutira Madzi | Imasintha ngodya ya jib kuti isinthe radius yogwirira ntchito (kufikira kwa ntchito) |
| Njira Yoyeretsera Magazi | Imapereka kuzungulira kosalekeza kwa 360° kuti ikwaniritse bwino malo ogwirira ntchito |
| Njira Yoyendera (Gantry) | Amayendetsa crane yonse m'mbali mwa njanji za quayside kuti ayikenso pamalo oyenera |
Njira zitatu zoyambirira zimaphatikizidwa mu superstructure yozungulira, zomwe zimathandiza kuti ntchito yoyenda nthawi imodzi ikhale yogwira ntchito bwino kwambiri. Njira yoyendera imalola crane kuyenda m'mbali mwa doko lonse, kuphimba malo angapo ogwirira ntchito ndi zombo kuchokera pamalo amodzi.
Mafotokozedwe Aukadaulo (Osinthika)
| Chizindikiro | Zosankha / Zosankha |
|---|---|
| Kukweza Mphamvu | 5 t – 300 t (yosinthika) |
| Utali wa Jib / Utali Wogwirira Ntchito | 15 m – 120 m |
| Kukweza Kutalika (pamwamba pa njanji) | Mpaka mamita 120 |
| Kuzama kwa Kukweza (pansi pa njanji) | 10 - 50 m |
| Gauge ya Sitima | 6 - 12 m (yosinthika) |
| Kapangidwe ka Jib | Truss jib / Box jib (ngati mukufuna) |
| Mtundu wa Jib | Jib imodzi / Jib yophatikizana ndi maulalo anayi |
| Magetsi | Mphamvu ya doko / Chozungulira cha chingwe |
| Dongosolo Lowongolera | Yopangidwa ndi PLC yokhala ndi ma drive osinthasintha osiyanasiyana |
Mafotokozedwe onse akhoza kusinthidwa kuti akwaniritse zofunikira zinazake za doko kapena malo osungiramo zombo.
Mapulogalamu
MAXTECH Portal Crane imagwira ntchito zosiyanasiyana m'madoko ndi m'malo osungira zombo:
Ntchito za Madoko ndi Malo Osungira Zinthu
Kusamalira katundu wambiri — malasha, miyala, tirigu, ndi zinthu zina zambiri pogwiritsa ntchito zida zogwirira
Katundu wamba — zitsulo, makina, ndi katundu wa polojekiti pogwiritsa ntchito zingwe
Kusamalira chidebe — chokhala ndi zofalitsira chidebe kuti chisamutsire bwino bokosi
Ntchito Zomanga Zombo
Kusonkhanitsa zombo za sitima — kukweza ndi kuyika magawo a zombo panthawi yomanga
Zovala - kukhazikitsa zida, makina, ndi machitidwe
Kukonza ndi kukonza zombo — kunyamula zinthu zolemera m'madoko ouma komanso m'mbali mwa malo ogona
