Kev txheeb xyuas tiav ntawm cov teeb meem sib xws nrog lub log crane
Crane log yog cov khoom siv cants rau cov khoom siv kev lag luam thiab cov tsav tsheb hnyav, raws li lawv cov kev ua haujlwm tseem ceeb thiab kev pabcuam lub neej ntawm cov khoom siv. Txawm li cas los xij, vim lub sijhawm ntev-thauj khoom siab, teeb tsa tsis raug lossis muaj lub log tsis raug, hnav, deforment, thiab txawm tias derailment muaj xwm txheej hnyav. Kab lus no yuav tob tob rau cov kev ua tsis tiav, ua rau lub log crane los pab cov tswv cuab cov tswv yim zoo thiab txuas lub neej ntawm lub log.
一, muaj teeb meem ntau nrogcrane log
1, rail tom
Rail tom yog hais txog kev sib txhuam ntawm lub log flange thiab ib sab ntawm txoj kev thaum lub log crane thaum ua rau txoj kev, uas ua rau
txawv txav thiab suab nrov. Rail tom qhov kev sib tw yog qhov muaj kev phom sij, suav nrog:
(1) nce log thiab taug kev hnav: nyob rau hauv ib txwm muaj rau ntau tshaj 5 xyoos, tab sis thaum ncua ntev yuav ua rau 1 xyoos.
(2) nce khiav tsis kam: ua rau lub cev muaj zog tshaj tawm thiab txawm tias tsav lub cev tawm dag.
(3) ua rau kev pheej hmoo txaus: Thaum muaj mob hnyav, lub log yuav nce mus rau txoj kev thiab ua rau cov khoom siv los ntxeev siab.
Lub ntsiab ua rau kev tsheb ciav hlau tom:
(1) kab rov tav / ntsug log sib txawv: kev teeb tsa yuam kev lossis cov choj deformation ua rau lub log kom tsis txhob sib tw rau txoj kev khiav.
(2) Kev sib txuas lus Asyncchrany: piv txwv li, lub cev muaj zog ntawm ob sab yog tsis sib xws lossis tus brakes tsis hloov kho tusyees.
(3) Kev teeb meem kev sib tw ntawm kev sib tw tiv thaiv kev sib tw: taug qab qhov chaw, qhov siab lossis ncaj yog tawm ntawm kev thev taus
2, lub log hnav
Crane logyog raug rau cov nra hnyav rau lub sijhawm ntev, thiab cov ntaub ntawv tseem ceeb ntawm hnav muaj xws li:
(1) Tread hnav: Yog tias cov thawj tuab tshaj 15%, nws yuav tsum tau hloov lossis kho.
(2) Rim Hnav: Yog tias cov hnav ncav cuag 50% lossis muaj kev so, nws yuav tsum tau raug kaw.
(3) crushing ntawm cov txheej tawv tawv: tsis muaj qhov tob ntawm quenching txheej (yuav tsum muaj ntau dua los yog sib npaug rau 20mm) ua rau muaj kev ua yeeb yam saum npoo.
(4) Lub log tawg: Yog tias pom tau pom, nws yuav tsum tau hloov tam sim ntawd, txwv tsis pub nws yuav tawg thiab ua rau muaj kev sib tsoo.
2, cov ntsiab lus thiab cov lus qhia txij nkawm
(1) Kho lub log chav
Kev kho ntawm kab rov tav deflection: kho cov kev coj tus kheej lossis tshem tawm cov shims los xyuas kom meej tias qhov deflection yog tsawg dua lossis sib npaug nrog lub log lub taub).
Kev kho ntawm txoj kev ntsug
Kev hloov kho span thiab kab phuv ntawm lub trolley tsawg dua los yog sib npaug rau ± 7mm, thiab lub trolley tsawg dua los yog sib npaug rau ± 3 hli.
(2) Ua kom zoo dua cov kev xa khoom
Synchronous tsav lub cev muaj zog: xyuas kom meej tias cov qauv muaj zog thiab cov tsis muaj nyob ntawm ob qho kawg yeej tsis sib txawv.
Braker sib npaug hloov kho: Lub zog braking ntawm ob sab yuav tsum yog tib yam kom tiv thaiv asynchronous braking.
(3) Taug qab kev txij nkawm thiab log hloov
Nquag xyuas cov kev khiav: Ntsuas cov kev khiav haujlwm thiab qib kev kawm txhua 6 lub hlis, thiab roj kom huv thiab te.
Hloov cov log log: Qhov kev sib txawv ntawm cov log tsav yog tsawg dua lossis sib npaug ntawm 0.1%, thiab lub log tsav tsawg dua lossis sib npaug nrog 0.2%.
