Kev siv, nta thiab qauv ntawm crawler cranes
Crawler crane yog ib qho crane uas nruab cov cuab yeej nqa ntawm lub crawler chassis. Ntxiv nrog rau kev siv lifting kev khiav hauj lwm hauv kev lag luam thiab pej xeem kev tsim kho thiab cov khoom siv installation, lwm yam khoom siv ua haujlwm tuaj yeem hloov lossis ntxiv, thiab nws kuj tseem siv tau los ua lub hauv ntej shovel, ruber, thiab lwm yam. Siv tshuab xws li shovels, grabs. , drilling tshuab, pawg tsav tsheb thiab underground diaphragm phab ntsa groovers. Rau kev nqa cov haujlwm, nws tuaj yeem hloov mus rau hauv crawler-hom ntauwd crane. Qhov no crawler-hom ntauwd crane tsis tas yuav nteg rails los yog nchuav cov pob zeb hauv paus thaum tsim kho, uas tuaj yeem txo qhov chaw tsim kho thiab cov nqi tsim kho. Yog li ntawd, crawler crane yog ib hom khoom siv dav siv. Muaj peb hom kev sib kis ntawm crawler cranes: mechanical, hydraulic thiab hluav taws xob. Tam sim no, hydraulic kis tau tus mob feem ntau yog siv.
Vim qhov chaw sib cuag loj ntawm lub crawler thiab hauv av, qhov nruab nrab ntawm lub ntiajteb txawj nqus yog tsawg, thiab qhov nruab nrab qhov tshwj xeeb siab me me, lub crawler crane tuaj yeem ua haujlwm ntawm cov av nkos thiab mos. Nws muaj peev xwm traction loj, muaj peev xwm nce toj, tuaj yeem tsav hauv av ntxhib, muaj peev xwm nqa loj thiab ruaj khov zoo. Cov cuab yeej crawler ntawm ib qho loj crawler crane tuaj yeem tsim los ua kab rov tav telescopic kom nthuav dav qhov txhawb nqa. Qhov tsis zoo ntawm crawler cranes yog lawv qhov hnyav thiab kev tsav tsheb tsawg, yog li lawv tsis haum rau kev ua haujlwm ntev. Thaum hloov chaw ua haujlwm, lawv yuav tsum tau thauj los ntawm kev tsheb ciav hlau lossis nqa los ntawm cov tsheb thauj khoom flatbed kom tsis txhob muaj kev puas tsuaj rau txoj kev.
Cov qauv ntawm crawler crane muaj cov pab pawg, hom, cov ntsiab lus tseem ceeb thiab cov lej sib txawv raws li hauv qab no:
Crawler crane labeling piv txwv: QUY100-hydraulic crawler crane, qhov siab tshaj plaws lifting peev yog 100t.
(2) Cov qauv yooj yim ntawm crawler crane
Lub crawler crane yog ib qho crane uas nruab cov cuab yeej nqa ntawm lub crawler chassis. Nws txoj haujlwm ua haujlwm zoo ib yam li lub log crane. Lub boom feem ntau siv cov qauv truss uas tuaj yeem txuas ntxiv.
Ntxiv nrog rau kev siv los ua ib lub crane, nws kuj tseem siv tau los ua ib qho crawler pawg ncej. Nws yog tsuas yog tsim los ntawm boom, ua hauj lwm mechanism, turntable, mus ncig teb chaws ntaus ntawv, lub hwj chim ntaus ntawv, hydraulic system, hluav taws xob system thiab kev ruaj ntseg ntaus ntawv. Tag nrho hydraulic tsav yog saws, thiab lub cav diesel tsav lub twj hydraulic. Lub siab roj tso tawm los ntawm lub twj tso kua mis hydraulic yog xa mus rau hydraulic motors ntawm lub lifting, luffing, slewing thiab mus ncig teb chaws mechanisms los ntawm lub valve tswj los tsim torque, thiab ces kis mus rau lub reel los ntawm lub reducer. , tsav tsheb log, thiab lwm yam, kom ua tiav ntau yam kev ua. Lub lifting thiab slewing mechanism ntawm crawler crane yog zoo sib xws los yog tib yam li ntawm lub log crane, thiab mus ncig teb chaws mechanism yog zoo sib xws los yog tib yam li cov hydraulic excavator. Lub luffing mechanism txais cov hlua hlau los rub lub winding luffing.
Main technologies ntawm crawler cranes. Parameters: siab tshaj lifting muaj peev xwm, siab tshaj lifting qhov siab, ua hauj lwm ntau yam, ua hauj lwm ceev, tshuab hnyav thiab lub zog, thiab lwm yam.
