Yese Kusimudza uye Kufamba Kaviri Girder Gantry Crane Inotengeswa

Iyo double girder gantry crane inorema-basa rekusimudza mhinduro yakanyatsogadzirirwa kubata hombe uye yakakura mitoro munzvimbo inoda maindasitiri. Iine yakasimba kaviri-girder uye gantry chimiro, iyo crane inopa yakasarudzika yekusimudza kugona, yakagadzikana inoshanda chikuva, uye yakavimbika-yakareba kuita. Iyo yakashongedzerwa nematrolley echokwadi uye masisitimu emagetsi epamberi, kuve nechokwadi chakatsetseka, chinoshanda, uye chechokwadi kubata kwezvinhu zvakasiyana-siyana.

Inoratidzira yakakura span, inogadzirika inosimudza kureba, compact chimiro, uye inochinjika kushanda, iyo mbiri girder gantry crane inowana yakasimba-yekutakura mutoro uye yakakwirira saiti kushandiswa. Izvi zvinoita kuti ive yakakodzera kune dzakasiyana siyana dzekushanda, kusanganisira zviteshi, nzvimbo dzengarava, mafekitori, matura, uye mayadhi makuru ekunze ekuchengetera. Zvekushandisa zvekunze, crane inogona zvakare kuve nemidziyo yekuchengetedza uye yekudzivirira senge njanji inosungirira, anchoring zvishandiso, tambo anchoring masisitimu, uye kumhanya kwemhepo kana mhepo inotungamira mita kuti ive nechokwadi chekushanda kwakachengeteka uye kwakagadzikana pasi pemamiriro ekunze akasiyana.

Kuenzaniswa negirder cranes imwe chete, iyo kaviri girder gantry crane inopa yakakwirira kusimudza masimba, yakanyanya kuomesesa zvigadziriso, uye yakakura kuchinjika kune inorema-basa uye inoenderera mashandiro. Yakanyanya kukodzera kusimudza mitoro inorema zvakanyanya, kushanda mumamiriro ezvinhu akaomarara, kana kusangana nezvimwe zvakakosha zvekushandisa. Nehukuru hwekusimudza hunosvika matani mazana matatu nemakumi maviri mumapurojekiti edu, madhizaini akadai separefu, kusimudza kureba, uye basa rekushanda rinogona kugadzirwa kuti rizadzise zvido zvakasiyana zvemaindasitiri.

Pakambani yedu, isu tinoisa pamberi pemhando uye chengetedzo pane yakaderera mitengo nzira. Yese yakapetwa kaviri girder gantry crane inogadzirwa nemaitiro akasimba kuti ave nechokwadi chekuvimbika, kusimba, uye kuchengetedzwa kwemushandisi. Nemasimba aya, iyo mbiri girder gantry crane yave chinhu chakakosha chemidziyo mukugadzirwa kwemazuva ano maindasitiri uye kubata zvinhu.

Magidhi: Iwo magidhi makuru anorema-basa bhokisi kana truss matanda akagadzirwa kubva kune yakakwirira-yakasimba simbi yekugadzira (semuenzaniso, Q345B kana yakaenzana). Kaviri girder dhizaini yakajairika ye40 t chiyero, ichipa kuomarara uye simba. Bhokisi magidhi anopa fomu yakasimba, yakasimba; truss girders (anoshandiswa pane yedu Truss Gantry modhi) kuderedza huremu kwenguva refu kwazvo. Magidhi akaiswa weld chaiyo uye kusagadzikana-kurerutswa kuderedza deformation. Iyo span (kureba pakati pemakumbo kana mavhiri) uye girder kureba zvinogadzirwa maererano nemutoro uye basa rekirasi. Marori ekupedzisira anobatana kune magirders uye anogara mavhiriseti ekufamba kwe crane.

Trolley uye Hoist: Trolley (kana gakanje) inomhanya panjanji pamusoro pemagidhi uye inotakura nzira yekusimudza. Kune 40 t huwandu, isu tinowanzo shandisa waya-tambo hoist ine yakasimba gearbox uye mota. Chikwidziso chinosanganisira tambo yesimbi yakaiswa padhiramu, mabhureki e-multi-plate friction, uye block ine hoko inorema. Mune mamwe magadzirirwo twin-hoist trolley (maviri hoist pane rimwe girder) inowanikwa kune yakareba-span yekusimudza kugovera. Iyo yekusimudza kumhanya uye torque inosangana nebasa reiyo crane (semuenzaniso, FEM/ISO ratings). Chengetedza ma switch ekumusoro/akaderera kufamba anodzivirira kubva kune-pamusoro-hoist kana pamusoro-pasi. Ese hoist akagadzirirwa ISO neCMAA zviyero, uye tambo yewaya inosangana ne ISO 4309 (kuongorora uye kutarisirwa). The trolley frame is welded steel, uye mavhiri ane profiled simbi ane akavharwa mabhengi.

Makumbo uye Zvitsigiro: Kune njanji-yakaiswa njanji, makumbo emakumbo akaomeswa bhokisi-chikamu makoramu, akanyatso kuenderana nematanda erunway. Flexible-gumbo dhizaini inowanika kugadzirisa kudiki kumisa nzira. Gumbo rega rega rinotakura mota dzekutyaira (marori ekupedzisira) uye mavhiri anotenderera panjanji. Makumbo akasungirirwa kumagidhi kuti agadzikane. Kune RTG cranes, iwo "makumbo" ndiwo makuru efodhi furemu makoramu ane matai makuru epneumatic. RTG makumbo eimba hydraulic cylinders anotungamira mavhiri uye anotsigira zambuko. Ese maumbirwo emakumbo akapendwa nemaindasitiri machira ekudzivirira mamiriro ekunze (eg kunze anti-corrosion pendi).

Madhiraivha uye Mota: Rori yega yega inofambiswa neiyo AC mota yakasanganiswa negiya bhokisi rekufamba rakatsetseka bhiriji. Kufamba kwetrolley kunoshandisawo mota uye gearbox (yakaparadzana nemadhiraivha ebhiriji). Motokari dzine simba rinodiwa (kazhinji rinosvika kumakumi e kW) uye rinofananidzwa nekutenderera kwebasa. Kune ma crane ane rabha-taira, injini dzedhiziri dzine hydraulic dhiraivha dzinogona kufambisa crane (yakajairwa pamaRTG mazhinji), kana isu tinopa ese-magetsi maRTGs (ane onboard jenareta kana bhatiri). Mamotor ese ane maindasitiri ekudzivirira uye IP ratings (kazhinji IP54 kana zvirinani). Variable Frequency Drives (VFDs) anowanzo shandiswa kudzora kumhanya kwakanaka uye kuchengetedza simba pakufamba kwebhiriji uye trolley.

Electrical System: Iyo crane's magetsi ekudzora sisitimu inoiswa pakati pepasi-yakaiswa kana madziro-yakaiswa panhi, yakavakirwa kuIEC zviyero. Kudzora kunosanganisira kutanga/kumisa uye gwara rekusimudzira, trolley, uye kufamba kwebhiriji. Sarudzo dzemagetsi dzinosanganisira conductor bar (busbar), tambo reel (festoon system), kana yekunze yekubatanidza (yeRTG cranes). Nzira dzekudzora dzinogona kunge dziri push-bhatani pendant chiteshi, kabhini opareta koni, kana isina waya yekudzora kure. Chengetedzo maseketi anoshandisa maindasitiri ekubatanidza uye relay, uye sarudzo PLC kutonga inowanikwa otomatiki (semuenzaniso, programmable anti-kudhumhana kudzora pakati cranes). Emergency stop circuits ishoma. Iyo sisitimu inosanganisira magetsi ekudzivirira emagetsi (mafuse, overload relays) uye grounding pane OSHA/ANSI zvinodiwa.

Midziyo Yekuchengetedza: Yedu 40 Ton Gantry Cranes inosanganisa akawanda ekuchengetedza michina. Izvi zvinowanzo sanganisira kuchengetedzwa kwekuremerwa (mutoro maseru kana kudzikisira zvishandiso) kudzivirira kusimudza kupfuura yakayerwa kugona; ekumusoro/yepasi muganho anochinja kuti amise rwendo rwekusimudza panzvimbo dzekupedzisira; machinjiko emuganho wekufamba kwebhiriji kudzivirira kuwanda kwenzira; mabhatani ekumisa emergency anosvikirwa nemushandisi; uye varindi vanodzivirira kumativi ekufambisa. Anti-kudhumhana zvishandiso (radar kana laser sensors) inogona kuiswa pamagireni emidziyo kudzivirira kusangana pakati pema cranes ari padyo. Optional features zvinosanganisira anti-sway control (kunyorovesa mutoro wekuswing) uye kamera-kuona masisitimu. Yese maturusi ekuchengetedza anoedzwa panguva yekutumwa, uye dunhu rinosangana neOSHA uye ASME kuchengetedza kodhi zvinodiwa.
