Puas elastic fastening tshuab ua haujlwm zoo nrog nruj DIN 536 crane ntsia?
Yog lawm, qhov tseeb, siv cov txheej txheem elastic fastening nrog nruj DIN 536 crane rails tsis yog ib lub tswv yim zoo xwb - nws yog suav tias yog lub ntiaj teb no engineering tus qauv thiab kev coj ua zoo tshaj plaws rau hnyav - lub luag haujlwm crane khiav.
Txawm hais tias nws yuav zoo li tsis txaus ntseeg rau kev sib koom ua ke ntawm txoj kev tsheb ciav hlau nruj heev nrog cov txheej txheem elastic fastening, qhov nruj heev ntawm DIN 536 ntsia yog vim li cas elastic fastening yuav tsum tau.
Nov yog cov ncauj lus kom ntxaws txog engineering vim li cas ob lub ntsiab lus no ua haujlwm zoo ua ke:
1. Nkag siab txog DIN 536 Crane Rail
DIN 536 rails (xws liA45, A75, A100, A120, thiab lwm yam) tshwj xeeb yog tsim los rau hnyav -cov haujlwm crane. Lawv muaj lub hauv paus dav, lub vev xaib tuab, thiab qis profile. Qhov geometry no ua rau lawv nruj heev yog li lawv tuaj yeem txhawb nqa loj, muaj zog log loads los ntawm overhead cranes, gantry cranes, thiab automated storage systems.

2. Vim li cas Rigid Rails xav tau Elastic fastenings
Thaum lub log loj loj dov hla lub tsheb ciav hlau DIN nruj, txoj kev tsheb ciav hlau tsis khoov ntau, tab sis cov qauv kev txhawb nqa (steel girder lossis pob zeb hauv paus) yuav inevitably flex lossis deflect me ntsis.
Yog hais tias lub tsheb ciav hlau yog rigidly bolted los yog welded rau lub hauv paus:
- Lub ntuj deflection ntawm lub girder yuav sim rub lub tsheb ciav hlau.
- Vim tias txoj kev tsheb ciav hlau khov kho, nws yuav tiv thaiv kev khoov, tsim kom muaj zog "pry- tawm" loj heev.
- Qhov no yuav sai sai ua rau sheared bolts, tawg pob zeb, tawg welds, thiab structural qaug zog.
3. Cov txiaj ntsig ntawm Elastic Fastening System
Qhov tseeb elastic system muaj ob qhov tseem ceeb: ib qho txuas ntxiv elastomeric ncoo hauv qab txoj kev tsheb ciav hlau, thiab caij nplooj ntoos hlav-loaded (elastic) clips tuav lub tsheb ciav hlau. Thaum ua ke nrog DIN 536 rail, lawv muab cov txiaj ntsig hauv qab no:
- Load Distribution:Lub nruam roj hmab ncoo nyob rau hauv lub hauv paus dav ntawm DIN rail flattens tawm nyob rau hauv lub log load, faib lub loj taw tes load tusyees mus rau hauv lub girder los yog lub hauv paus. Qhov no tiv thaiv localized crushing.
- Absorption ntawm Dynamic Forces:Cov cranes tsim cov khoom hnyav hnyav (kev vibration, braking, lifting, thiab lateral swaying). Cov ntaub qhwv elastic thiab cov roj hmab "qhov ntswg" ntawm cov clips ua raws li kev poob siab absorbers, tiv thaiv lub hauv paus los ntawm kev puas tsuaj.
- Chaw nyob ntawm Thermal Expansion:Steel rails nthuav dav thiab cog lus nrog kev hloov pauv kub. Elastic clips siv lub siab qis qis los tuav txoj kev tsheb ciav hlau hauv qhov chaw ruaj ntseg, tab sis lawv tseem tso cai rau txoj kev tsheb ciav hlau kom swb ntev raws li nws nthuav dav, tiv thaiv txoj kev tsheb ciav hlau los ntawm buckling.
- Tshem tawm ntawm Fretting Corrosion:Yog hais tias ib tug nruj rail zaum ncaj qha rau ntawm ib tug steel girder, lub microscopic txav tshwm sim los ntawm hnyav crane tsheb ua zoo li cov ntawv xuab zeb, hnav tam sim ntawd ob lub tsheb ciav hlau puag thiab lub girder (fretting). Lub elastic ncoo kiag li cais ob hlau.
- Lateral Adjustability:DIN rails feem ntau xav tau kev sib raug zoo. Elastic clip systems yog tsim los nrog cam eccentrics lossis slotted qhov uas tso cai rau kev hloov kho ntawm sab nraud thaum lub sijhawm teeb tsa thiab kev saib xyuas, kom ntseeg tau tias lub log crane tsis sib tsoo tawm tsam lub taub hau.
Dab tsi yog qhov txawv ntawm DIN 536 crane ntsia thiab QU crane ntsia?
Thaum ob qho tib si DIN 536 thiab QU crane rails tau tsim tshwj xeeb los txhawb nqa hnyav -cov dej num overhead thiab gantry cranes, lawv ua raws li cov qauv hauv cheeb tsam sib txawv. Yog li ntawd, lawv txawv heev nyob rau hauv lawv cov geometry, cov khoom specifications, thiab kev siv thoob ntiaj teb.
Ntawm no yog qhov sib txawv ntawm qhov sib txawv tseem ceeb ntawm ob:
1. Keeb kwm thiab cov qauv
- Qauv TSIS MUAJ: DIN 536Qhov no yog European (keeb kwm German) tus qauv rau crane ntsia. Nws yog arguably lub feem ntau dav lees paub crane rail qauv thoob ntiaj teb, hnyav siv nyob rau hauv cov teb chaws Europe, Americas, Middle East, thiab thoob ntiaj teb chaw nres nkoj tej yaam num.
- QU Rails:Cov no ua raws li Suav lub teb chaws tus qauv (tshwj xeeb yog YB / T 5055). Cov tsiaj ntawv "QU" los ntawm Suav pinyin lo lus Qizhongji, uas txhais ncaj qha rau "crane." Cov tsheb ciav hlau no yog lub neej ntawd nyob hauv Suav teb thiab tau siv ntau hauv cov cheeb tsam uas Suav EPC (Engineering, Procurement, and Construction) cov tuam txhab ua haujlwm, xws li cov teb chaws Asia thiab thaj tsam ntawm Africa.
2. Lub npe Conventions
Ob tus qauv siv tsab ntawv sau npe ua raws li tus lej, thiab ob qho tib si, tus lej sawv cev rau qhov dav dav ntawm lub taub hau tsheb ciav hlau hauv millimeters.
- DIN 536 siv tsab ntawv "A". Cov profiles muaj xws li A45, A55, A65, A75, A100, A120, thiab A150. (Piv txwv li, A100 rail muaj 100 mm dav lub taub hau).
- QU siv "QU". Tus qauv profiles yog QU70, QU80, QU100, thiab QU120. (Ib lub QU100 rail kuj muaj 100 mm dav lub taub hau).

| qw 80 | 80 | 130 | 130 | 32 | 64.41 | 50~75 |
| QU 100 | 100 | 150 | 150 | 38 | 89.05 | 100~125 |
| qw 120 | 120 | 170 | 170 | 44 | 118.50 | 160 |
3. Profile thiab Geometry (Qhov txawv loj tshaj)
Txawm hais tias koj piv A100 thiab QU100 (uas ob qho tib si muaj 100mm lub taub hau dav), lawv tus ntoo khaub lig- cov duab ntu sib txawv heev.
DIN 536 (Squat thiab dav):DIN rails nto moo rau lawv qhov profile tsis tshua muaj neeg. Lawv muaj ib tug loj, incredibly dav puag thiab luv luv nyob rau hauv qhov siab.
- Piv txwv li: DIN A100 muaj qhov siab ntawm 95 hli thiab lub hauv paus dav ntawm 200 hli.
- Qhov zoo: Lub ultra- dav hauv paus faib thauj khoom hla thaj chaw loj heev, txo qhov siab ntawm pob zeb lossis steel girder hauv qab no.
QU Rails (Taller thiab Boxier):QU rails zoo li me ntsis zoo li cov tsheb ciav hlau tsoos tab sis tuab dua. Lawv siab dua DIN ntsia hlau thiab muaj lub hauv paus nqaim txheeb ze rau lawv qhov siab.
- Piv txwv li: QU100 muaj qhov siab ntawm 150 hli thiab lub hauv paus dav ntawm 150 hli.
- Qhov zoo: Vim tias lawv siab dua, QU ntsia hlau muaj qhov ntsug ntsug ntsug ntau dua (lub sijhawm ntawm inertia), txhais tau hais tias lawv nthuav dav me me hauv kev txhawb nqa txuas ntxiv me ntsis zoo dua li squat DIN ntsia.
4. Cov qib steel thiab cov khoom siv
Vim tias lawv los ntawm cov txheej txheem sib txawv, lawv tau tsim los siv cov qib steel sib txawv.
- DIN 536 railfeem ntau yog dov hauv European tus qauv qib raws li lub zog tensile, feem ntau 690 N / mm² lossis siab dua - hnav 880 N / mm² (feem ntau teev raws li qib xws li R260 lossis S900A).
- QU covyog dov feem ntau siv Suav siab -manganese rail hlau, nrog U71Mn yog qib ntau tshaj. U71Mn muaj kev hnav zoo heev thiab lub zog tensile uas feem ntau tshaj 880 MPa, ua rau nws zoo sib xws rau sab sauv -tier DIN cov ntaub ntawv.
