Universal Lifting and Traveling Double Girder Gantry Crane Ogulitsa

Double girder gantry crane ndi njira yonyamula katundu wolemetsa yomwe idapangidwa kuti izitha kunyamula katundu wamkulu komanso wokulirapo m'malo ofunikira mafakitale. Ndi mawonekedwe ake olimba awiri-girder ndi gantry, crane imapereka mphamvu zokweza zapadera, nsanja yokhazikika yogwirira ntchito, komanso magwiridwe antchito odalirika a nthawi yayitali. Ili ndi ma trolleys olondola komanso makina apamwamba amagetsi, kuwonetsetsa kuti zinthu zikuyenda bwino, zogwira mtima komanso zolondola pamapulogalamu osiyanasiyana.

Pokhala ndi chitalikirapo chachikulu, kutalika konyamulira kosinthika, mawonekedwe ophatikizika, ndi magwiridwe antchito osinthika, crane ya double girder gantry imakwaniritsa mphamvu zonyamula katundu komanso kugwiritsa ntchito malo apamwamba. Izi zimapangitsa kuti zikhale zoyenera kugwira ntchito zosiyanasiyana, kuphatikizapo madoko, malo osungiramo zombo, mafakitale, malo osungiramo katundu, ndi mabwalo akuluakulu osungiramo kunja. Kwa ntchito zakunja, crane imathanso kukhala ndi zida zodzitetezera komanso zodzitchinjiriza monga zomangira njanji, zida zoyimbira, makina oyika chingwe, komanso liwiro la mphepo kapena ma mita owongolera mphepo kuti zitsimikizire kuti zikugwira ntchito motetezeka komanso mokhazikika nyengo zosiyanasiyana.

Poyerekeza ndi ma cranes a single girder, crane ya double girder gantry crane imapereka mphamvu zokweza kwambiri, masinthidwe ovuta kwambiri, komanso kusinthasintha kwakukulu pantchito zolemetsa komanso mosalekeza. Ndikoyenera makamaka kunyamula katundu wolemera kwambiri, kugwira ntchito m'malo ovuta kwambiri, kapena kukwaniritsa zofunikira zina zapadera. Ndi mphamvu zokweza kwambiri zomwe zimafika mpaka matani 320 m'mapulojekiti athu, magawo apangidwe monga kutalika, kukweza kutalika, ndi ntchito yogwirira ntchito zitha kupangidwa kuti zikwaniritse zosowa zamakampani osiyanasiyana.

Pakampani yathu, timayika patsogolo ubwino ndi chitetezo kuposa njira zotsika mtengo. Crane iliyonse ya double girder gantry crane imapangidwa ndi miyezo yokhazikika kuti iwonetsetse kudalirika, kulimba, komanso chitetezo cha ogwiritsa ntchito. Ndi mphamvu izi, double girder gantry crane yakhala chida chofunikira pakupanga mafakitale amakono ndi kusamalira zinthu.

Zomangamanga: Zomangamanga zazikulu ndi bokosi lolemera kwambiri kapena matabwa opangidwa kuchokera ku chitsulo champhamvu kwambiri (mwachitsanzo, Q345B kapena chofanana). Mapangidwe a Double girder ndi ofanana ndi 40 t mphamvu, kupereka kuuma ndi mphamvu. Zomangamanga za bokosi zimapereka mawonekedwe ophatikizika, olimba; ma truss girders (omwe amagwiritsidwa ntchito pazithunzi zathu za Truss Gantry) amachepetsa kulemera kwa nthawi yayitali kwambiri. Ma girders amawokeredwa ndendende ndikuchepetsa kupsinjika kuti achepetse kupunduka. Kutalika (kutalika pakati pa miyendo kapena mawilo) ndi kutalika kwa girder kumapangidwa malinga ndi katundu ndi ntchito. Magalimoto omaliza amalumikizana ndi ma girders ndikuyika mawilo oyendera ma crane.

Trolley ndi Hoist: Trolley (kapena nkhanu) imayendetsa njanji pamwamba pa zomangira ndipo imanyamula njira yokwezera. Pakutha kwa 40 t, timakonda kugwiritsa ntchito cholumikizira cha waya chokhala ndi gearbox yolimba komanso mota. Chokwezacho chimakhala ndi chingwe chachitsulo chokhomeredwa pa ng'oma, mabuleki amitundu yambiri, ndi chipika chokhala ndi mbedza yolemera. M'mapangidwe ena trolley ya twin-hoist (zokweza ziwiri pa girder imodzi) zimapezeka kuti zitha kugawa kwanthawi yayitali. Kuthamanga ndi torque kumayenderana ndi ntchito ya crane (mwachitsanzo, FEM/ISO ratings). Kuchepetsa ma switch oyenda kumtunda / kutsika kumateteza kumtunda kapena kutsika kwambiri. Zokweza zonse zidapangidwa motsatira miyezo ya ISO ndi CMAA, ndipo chingwe chawaya chimakwaniritsa ISO 4309 (kuyang'anira ndi chisamaliro). Choyimira cha trolley ndi chitsulo chowotcherera, ndipo mawilo amapangidwa ndi chitsulo chokhala ndi zitsulo zosindikizidwa.

Miyendo ndi Zothandizira: Kwa ma cranes okhala ndi njanji, mafelemu amiyendo ndi mizati yolimba yamabokosi, yolumikizidwa ndendende ndi mizati ya njanji. Mapangidwe a mwendo wosinthika amapezeka kuti azitha kuwongolera molakwika kanjira kakang'ono. Mwendo uliwonse umanyamula ma motors (magalimoto omaliza) ndi mawilo omwe amagudubuza panjanji. Miyendo imamangiriridwa ku zomangira kuti zikhazikike. Kwa ma cranes a RTG, "miyendo" ndiye mizati yayikulu yamafelemu okhala ndi matayala akulu opumira. Miyendo ya RTG yokhala ndi ma hydraulic silinda omwe amawongolera mawilo ndikuthandizira mlatho. Miyendo yonse imapakidwa utoto ndi zokutira zamafakitale kuti zitetezere nyengo (monga utoto wakunja woletsa dzimbiri).

Ma Drives ndi Motors: Galimoto yomaliza iliyonse imayendetsedwa ndi mota ya AC yophatikizidwa ndi bokosi la gear kuti iyende pamlatho wa crane. Ulendo wa trolley umagwiritsanso ntchito injini ndi gearbox (zosiyana ndi zoyendetsa mlatho). Ma motors ali ndi mphamvu yofunikira (nthawi zambiri mpaka makumi a kW) ndipo amafananizidwa ndi kayendetsedwe ka ntchito. Kwa ma crane opangidwa ndi labala, ma injini a dizilo okhala ndi ma hydraulic amatha kuyendetsa crane (yokhazikika pama RTG ambiri), kapena timapereka ma RTG amagetsi onse (okhala ndi jenereta yapaboard kapena batire). Ma motors onse ali ndi zotchingira mafakitale ndi ma IP (nthawi zambiri IP54 kapena kuposa). Ma Variable Frequency Drives (VFDs) nthawi zambiri amagwiritsidwa ntchito powongolera liwiro komanso kupulumutsa mphamvu pakuyenda mlatho ndi trolley.

Dongosolo lamagetsi: Makina owongolera magetsi a crane amakhala pakatikati pagawo lokwera pansi kapena pakhoma, lomangidwa motsatira miyezo ya IEC. Kuwongolera kumaphatikizapo kuyambika/kuyimitsidwa ndi mayendedwe a hoist, trolley, ndi mayendedwe a mlatho. Zosankha zamagetsi zimaphatikizapo kondakitala (basi), reel chingwe (festoon system), kapena zolumikizira zakunja (za RTG cranes). Njira zowongolera zitha kukhala poyambira batani, cholumikizira cholumikizira kanyumba, kapena chowongolera opanda zingwe. Mabwalo achitetezo amagwiritsa ntchito zolumikizira zamakampani ndi ma relay, ndipo kuwongolera kwa PLC kosankha kumapezeka kuti zizingochitika zokha (mwachitsanzo, zowongolera zoletsa kugundana pakati pa cranes). Mabwalo oyimitsa angozi ndi osowa. Dongosololi limaphatikizapo zida zodzitchinjiriza zamagetsi (ma fuse, ma relay ochulukira) ndikuyika pansi pazofunikira za OSHA / ANSI.

Zida Zachitetezo: Ma Cranes athu a 40 Ton Gantry amaphatikiza zida zingapo zotetezera. Izi zimaphatikizapo chitetezo chochulukirachulukira (ma cell olemetsa kapena zida zochepetsera) kuti apewe kukweza kupitirira kuchuluka kwake; kumtunda / kutsika malire masiwichi kuti ayimitse kuyenda kokweza pamalo omaliza; sinthani malire oyenda pamlatho kuti musadutse msewu wonyamukira ndege; mabatani oyimitsa mwadzidzidzi opezeka kwa woyendetsa; ndi alonda oteteza kuzungulira zigawo zosuntha. Zida zolimbana ndi kugundana (ma radar kapena masensa a laser) zitha kuikidwa pazingwe zachidebe kuti zipewe kulumikizana pakati pa ma cranes oyandikana. Zosankha zomwe mungasankhe zimaphatikizapo anti-sway control (kusinthira kunyowetsa katundu) ndi makina owonera makamera. Zida zonse zotetezera zimayesedwa panthawi yotumizidwa, ndipo zozungulira zimakwaniritsa zofunikira za chitetezo cha OSHA ndi ASME.
