Kev piav qhia |
| Log diameter (D) |
Φ160mm ~ Φ1000mm |
Kev qhia tshwj xeeb: Φ250mm, Φ400mm, Φ630mm, Φ800mm |
| Dav dav (B) |
80mm ~ 200mm |
Yuav tsum phim lub taub hau dav dav (piv txwv li, QU80 taug qab sib haum rau lub log dav ntawm kwv yees li 100mm). |
| Qhov siab (h) |
20mm ~ 50mm |
Muab ob npaug rau flange (universal), ib qho flange (tsawg lateral quab yuam), flangeless (yuav tsum tau qhia). |
| Khoom siv |
Cam khwb cia hlau (ZG340-640), forged steel 42CrMo, 65Mn |
Cam khwb cia hlau yog kev lag luam thiab ruaj khov, thaum cov hlau alloy muaj cov khoom siv siab load-bearing. |
| Thaum tshav kub kub kho hardness |
Log deg hardness: HB300 ~ 380 los yog HRC45 ~ 55 |
Deg hardening txhim kho hnav tsis kam. |
| Ib lub log load ntsuas |
5t ~ 500t |
Kev faib tawm nyob ntawm tag nrho cov crane hnyav thiab cov log tsheb (piv txwv li, plaub lub log crane nrog tag nrho cov load ntawm 100t muaj ib lub log load ntawm kwv yees li 25t). |
| Lub log siab tshaj plaws (P) |
50kN ~ 800kN |
Yuav tsum ua kom haum rau txoj kev taug qab lub peev xwm thauj khoom (piv txwv li, QU100 khiav tso cai rau lub log ntawm kwv yees li 300kN). |
Crane Rail Wheels Tej Teeb Meem thiab Kev Tu
Hnav:
Tread Wear: Uniform hnav nyob rau hauv ib txwm ua haujlwm.
Flange Wear: Tshwj xeeb tshaj yog txawv txav ntawm ib sab, feem ntau yog ib qho kev qhia ntawm "rail tom," yuav tsum tau kho.
Rail Biting: Kev sib txhuam hnyav ntawm lub log flange thiab sab ntawm txoj kev tsheb ciav hlau thaum lub sijhawm ua haujlwm crane. Qhov no yog ib qho ntawm cov teeb meem uas tshwm sim ntau tshaj plaws, ua rau kev hnav sai ntawm flange thiab kev tsheb nqaj hlau, nce kev khiav hauj lwm. Ua rau muaj xws li:
Rail installation yuam kev (nce, ncaj, ntsuas)
Log installation yuam kev (kab rov tav skew, ntsug skew, kab pheeb ces kaum yuam kev)
Tsav asynchrony
Ncej deformation
Peeling thiab chipping: Pitting, flaking, los yog flange chipping ntawm lub tread. Ua rau muaj xws li kev kho cua sov tsis raug, teeb meem ntawm cov khoom siv, lossis kev cuam tshuam ntau dhau.
Crane Rail Wheels Kho Cov Lus Qhia:
Kev tshuaj xyuas tsis tu ncua: Txheeb xyuas qhov hnav (tshwj xeeb yog flange thickness), tawg, thiab tev.
Lubrication: xyuas kom meej lubrication ntawm bearings.
Rail Cleaning: Khaws cov ntsia hlau kom huv si, tsis muaj weld slag, gravel, thiab lwm yam khoom tawv.
Kev Ntsuas thiab Kev Kho Kom Zoo: Tsis tu ncua xyuas qhov sib luag, qhov ncaj, thiab lub log skew ntawm cov ntsia hlau, thiab kho tam sim ntawd.
Crane Rail Wheels Xaiv thiab Hloov Cov Lus Qhia:
Ua ntej tsim qauv: Thaum hloov lub log, nws yog qhov zoo tshaj plaws los siv cov khoom ntawm tib tus qauv thiab cov lus qhia tshwj xeeb.
Xaiv cov neeg tsim khoom ntseeg tau: Cov log yog cov khoom siv nyab xeeb; xaiv cov tuam txhab tsim nyog nrog cov txheej txheem paub tab (tshwj xeeb tshaj yog cov txheej txheem kho cua sov).
Hloov hauv Pairs: Nyob rau tib lub tsheb lossis sab, nws raug nquahu kom hloov txhua lub log ib txhij lossis tsawg kawg hauv ob lub log (piv txwv li, ob lub log tsav) kom ntseeg tau txoj kab nruab nrab thiab tsis txhob ua haujlwm asynchronous.
Match Rail Condition: Yog hais tias cov ntsia hlau tseem hnav hnyav, tsuas yog hloov lub log yuav ua kom lawv hnav; xav txog kev kho lossis hloov cov ntsia hlau ib txhij.
