A rail ntses phaj yog ib qho kev sib koom ua ke uas tso cai rau cov tsheb ciav hlau sib cais ntev los ua tus kab nrib txuas ntxiv los ntawm kev xa tawm lub sijhawm bending thiab shear rog hla ib qho kev sib txuas uas tsis yog -welded.GNEE RAILmuaj cov phaj ntses sib xws nrog GB rails, UIC50–UIC60, DIN536 crane rails, QU crane rails, JIS rail qauv, AS1085 profiles, BS11 rails, thiab AREMA / ASCE systems, txhawb nqa los ntawm kev soj ntsuam zoo ua ntej xa khoom.
| Kev faib qeb | Hom Rail Joint | Core txhais / Cov yam ntxwv tseem ceeb |
| Los ntawm Txoj Haujlwm ntawm Txoj Kev | Square Joint | Cov pob qij txha nyob rau hauv parallel rails yog aligned opposite ib leeg. Feem ntau ntawm cov kab ncaj nraim; yooj yim tab sis ua rau muaj kev cuam tshuam ntau dua. |
| Kev sib koom ua ke | Cov pob qij txha ntawm ib txoj kev tsheb ciav hlau yog qhov chaw nruab nrab ntawm - taw tes ntawm txoj kev tsheb ciav hlau uas nyob ib sab. Feem ntau siv rau ntawm cov nkhaus kom txo cov rog thiab txhim kho kev caij tsheb zoo. | |
| Los ntawm txoj hauj lwm ntawm Sleepers | Txhawb Kev Sib Koom | Rail xaus so ncaj qha rau ntawm ib qho "joint sleeper". Minimizes deflection tab sis tsim ib tug nruj, siab -maintenance point. |
| Suspended Joint | Rail kawg yog nyob nruab nrab ntawm ob tug pw tsaug zog. Hom ntau tshaj; muab kev yooj yim tab sis yuav tsum tau saib xyuas ntau zaus. | |
| Choj Joint | Zoo ib yam li raug tshem tawm, tab sis siv lub phaj hlau txuas txuas rau ob sab ntawm qhov sib koom ua ke. Tsis siv dav. | |
| Los ntawm Kev Ua Haujlwm & Kev Siv | Ordinary (bolted) Joint | Standard kev twb kev txuas siv fishplates thiab bolts. Tus nqi- zoo, tso cai rau thermal expansion. |
| Kev sib haum xeeb | Txuas ob txoj hlua ntawm qhov sib txawv / profile. Siv cov phaj tshwj xeeb zoo li tus ntses los xyuas kom muaj kev hloov pauv. | |
| Conductive Joint | Ua kom muaj hluav taws xob txuas ntxiv ntawm cov kab tsheb ciav hlau rau traction tam sim no thiab cov teeb liab, siv cov khoom siv hluav taws xob. | |
| Insulated Joint (IRJ) | Hluav taws xob cais cov rail seem rau cov teeb liab. Siv cov ntaub ntawv insulating ntawm cov ntsia hlau thiab daim hlau. | |
| Welded Joint | Rail xaus yog fused ua ke (xws li, thermite welding). Tsim Nruam Welded Rail (CWR) rau kev sib tw, muaj zog dua. | |
| Frozen Joint | Ib qho mob uas nruj los yog corroded fishplates tiv thaiv thermal expansion/contraction, ua rau muaj kev ntxhov siab. | |
| Expansion Joint (REJ) | Tso cai tswj cov kev tsheb ciav hlau ntev (piv txwv li, ntawm cov txuas hniav) kom tiv thaiv buckling lossis tawg vim qhov kub hloov pauv. |
Nta ntawm Kev Sib Koom Tes Bar (Kev Sib Koom Tes Fishplate) rau Railway
Kev cuam tshuam kev sib koom ua ke (lossis cuam tshuam cov ntses phaj) yog cov tsheb ciav hlau tshwj xeeb tsim los txuas ob txoj kev tsheb ciav hlau nrog cov profiles sib txawv, qhov siab, lossis ntu, ua kom muaj kev hloov pauv. Cov yam ntxwv tseem ceeb muaj xws li kev cai,, asymmetric shaping rau aligning, sib txawv bolt qhov ntau thiab tsawg rau txawv rail web thicknesses, siab -lub zog forged / cam khwb cia hlau, thiab txo lub log- rail cuam tshuam, txhim khu kev ruaj ntseg thiab ruaj ntseg.
Cov yam ntxwv tseem ceeb thiab cov yam ntxwv:
- Asymmetric Design:Tsis zoo li cov txheej txheem sib koom ua ke, cov no yog tsim los kom haum cov kev tsheb ciav hlau sib txawv ntawm txhua qhov kawg (piv txwv li, 50kg txog 60kg, 43kg txog 50kg) txhawm rau txuas cov tsheb ciav hlau sib txawv, kom ntseeg tau tias lawv phim zoo kawg nkaus.
- High -Cov khoom siv zog:Ua los ntawm qib siab - cov ntaub ntawv hlau zoo li Q235, 45#, 50Mn, 42CrMo, lossis Q345, feem ntau kho nrog forging, tempering, lossis normalizing kom muaj kev hnav zoo dua thiab qaug zog.
