Girder crane: iinkcukacha kunye harateristiki

Kuzo zonke iinkalo zezinto ezenziwa girder yabantu nendwe zingasetyenziswa ukuhambisa imithwalo enzima. Oku yindlela ukunyusa elahliweyo kwi ukhwelisa (netroli), nto leyo ezinambuzelayo girder kwebhulorho. Olu hlobo oomatshini yenye yeyona ixhaphakileyo. Ekuqaleni kwenkulungwane yama-21 kwi kummandla elalisakuba yiSoviet Union, njengoko uqikelelo ezahlukeneyo, ngonyaka ukuvelisa iikopi-1 ukuya kwisi-1.5 lamawaka izityalo ezizodwa 17.

Ngokubanzi, ubume crane umqadi iqulathe nocamba ngangokolulwa kweminwe, wayedla ngokuba ibhulorho, yaye isiphelo exhasa. Ngemiqadi usekela zenziwe ngohlobo bemilo yoxande. Ngaphakathi ukuba babele ngokulinganayo ntshikilelo nokubonelela uzinzo beendonga nkqo ye emngxunyeni yi - iipleyiti zentsimbi welding kwikonw ngekona ukuya iindawo ngaphakathi. Crane girder iye ibhanti eliphezulu nengasezantsi. Ummandla eliphezulu ifakelwe umkhondo kaloliwe, apho sithembele imiqadi kweminwe. Yabeka okusemandleni azo ukuba bazibekele intshukumo tye. Kwicala ubuso imiqadi babonelelwa iqonga encinane handrail ngenxa crane nkonzo. Ngomhla zento umqadi imvelaphi inyuselwa Sibona. Ngexesha lentshukumo yokwakha uyahlangabezana ekhethekileyo drive, enziwe ngaphantsi amacebo ezahlukeneyo.

Drive kunye phakamisa crane umqadi

Indlela crane ukuba ukudluliswa ngombane drive kunye zezindlu okanye amavili etsobhileyo axhasayo. amavili zezindlu asetyenziswa kwimeko apho ukuthutha imithwalo lwenziwa kuphela kumgca othe ngqo. ukuthwala Tapered girder nendwe embindini phezu neentsimbi kwaye kusetyenziswa xa iindlela ziye kujikwa izabelo zikaloliwe. Le actuator angase ukulungiswa ngokungqinelana ne amacebo ezahlukeneyo kuyilo. Sibona sisigqeba yesakhelo ixhaswe ngokusebenzisa amavili imiqadi kweminwe. Yaqala indlela Ukunyusa - electric okanye manual, kwaye ibonelela limiter isebenza hook block. Ekukhanyeni-umsebenzi crane netroli njengoko lisetyenziswe ukhwelisa zombane, ezo ubeka zibambene kwisakhelo bogie.

Types of milenge msebe

Kuxhomekeka neempawu zolwakhiwo milenge girder kunokuba inkxaso, sijinga kunye gantry. Uhlobo lokuqala isakhiwo zixhonywe lwengoma kaloliwe overground - izithuba nkqo benza njengoko ixhasa apho imvelaphi inyuselwa ngomsonto kaloliwe. Ngokuqhelekileyo, i-crane inkxaso girder ezisetyenziswa ibala elivulekileyo ukuze usetyenziswe ukuthutha imithwalo ezinkulu enzima. milenge Okuza zisetyenziswa ngaphakathi kwaye ibekwe phambili zicaciswe kuyilo imiqadi wesakhiwo. inzuzo yazo engundoqo ubungakanani encinane ngobude, kwaye kuqatyeliswa kwiisayithi ezahlukeneyo ivenkile. track wabo nayo imilo yegophe.

yoyilo Gantry zisetyenziswa kuphela ukuthutha imithwalo multi-ton. Bethule isakhiwo isekela nkqo (ekwaziyo ihamba-moya oxwesileyo) kunye imiqadi tye. imihlaba yabo - kwempahla kunye nokwakhiwa imisebenzi.

milenge Girder ne yachuma

Indawo ekhethekileyo kwindawo yokwakha ubambe crane inqaba kunye girder boom. It is a uyilo aqhelekileyo xa kulayishwa kunye nokothula, indibano kunye nomsebenzi wokwakha kwiindawo ezahlukeneyo. Kwendyebo kwendwe olunjalo ezibunxantathu truss, imilo ezibuxande okanye isikwere.

Le boom ayinabantu ibhanti eliphezulu nengasezantsi. Kwi emazantsi lihamba netroli ubuso ifama nge actuator. Kwezinye iimeko, oko ingafakwa ngokuqinileyo kunye umqadi. Kulo mzekelo, intshukumo imithwalo kwi tyaba kwenzeka ngokushukumisa kwendyebo ecaleni sikhokelo ngokwayo.

Le umqadi unako ibekwe tye okanye kwi-engile ^malunga 30-45. Crane girder kunye boom lineqela iingenelo. Okokuqala, oko intshukumo olukhawulezayo kwempahla kwicala tye. Okwesibini, yinto kwendawo radius enkulu. Ekugqibeleni, ukungabikho amabala eemfama - kwendwe unako ukufumana impahla, nkqu kufutshane ngenkxaso.

Iimpawu milenge msebe

Kuxhomekeka umqadi amandla nendwe linokukwenziwa kwi lokuqala (ukuya m 5), le yesibini (50 m) okanye lesithathu (iitoni-320) qela. Le sokutsala into ngentambo ne electric drive isetyenziswa njengentsika ephakamise isigunyaziso. Ukuba umqadi uneempawu of duty nendwe kakhulu eziphakamileyo, lixhotyiswe iindlela ezimbini osusa: eziziprayimari nezizisekondari. Olunye uphawu ebalulekileyo ububanzi kweminwe crane umqadi. Ngaphezu koko - uyilo enkulu ngakumbi kukuba ngenxa yokuba ubukhulu lo mzuzu yokugoba ntshikilelo evela kwi midspan. Kukho izakhiwo multi-ngangokolulwa kweminwe, apho ezifakwe kwizakhiwo enkulu. Zisekelwe ngqo kwinani imiqadi - emancamini kwaye phakathi.

inkqubo yolawulo crane girder

ulawulo Crane kaninzi phansi. ulawulo Analog akhiwe kufutshane umqhubi, eziqhagamshelene kwiingcingo ukuya okukunyusa nokuphathwa iindlela. Remote - Enye indlela eqhelekileyo yolawulo. Iinkcukacha girder crane ngokuxhomekeke khompyutha, nto leyo, nelawulwa yi-umqhubi. Milenge ezilawulwa ukusuka endlwaneni zisetyenziswa kumaziko amakhulu orhwebo. Umqhubi, ibekwe elorini, lilawula inkqubo yonke zokuhamba. Le nendwe kufakwa alamu lokubonelela le wayeyinkcani, kunye neqonga okhethekileyo kuyanda.
