Vim li cas Gauge tsis yog tus tsav tsheb tiag ntawm Caij Nplooj Ntoos Hlav
Rail fastening springs (elastic clips) yog qhov loj los ntawm txoj kab tsheb ciav hlau, qhov chaw pw tsaug zog thiab lub qag load, thiab lub ntsuas ntsuas tsuas yog thawj lim. Ib txoj kab 1000 hli - ntsuas kab tuaj yeem nqa tib yam 50 kg / m rail raws li 1435 mm kab ntawm txoj kev thauj khoom hnyav, thiab tom qab ntawd nws siv cov clip zoo sib xws. Conversely, ib tug maj mam ua 1067 hli ceg kab nrog 22 kg / m rail xav tau ib tug me me caij nplooj ntoos hlav. Qhov kev sib piv ntawm 1067 mm thiab 1000 mm systems yog li kev sib piv ntawm rail seem thiab lub luag hauj lwm ntawm txhua lub network, thiab cov logic sizing yog tib yam nyob txhua qhov chaw: clip ntiv taw yuav tsum nias lub tsheb ciav hlau ko taw nrog lub zog sib tw rau lub qag load, thaum lub caij nplooj ntoos hlav yuav tsum nyob rau hauv nws elastic deflection ntau yam.
Rail Sections Hom ntawm 1067 mm thiab 1000 mm Kab
Ntawm nqaim-gauge (1067 mm) thiab meter-gauge (1000 mm) railways, rail mass nce nrog lub luag haujlwm. Ceg thiab teeb kab feem ntau siv 18-30 kg/m rail muab rau cov qauv tsheb ciav hlau xws li GB/T 11264; cov kab tseem ceeb feem ntau siv 37-50 kg/m rail; thiab hnyav-txoj kev nqaim-gauge txoj hauv kev, xws li cov hlau-ore kab nyob rau sab qab teb Africa, siv cov tsheb ciav hlau mus txog 57 kg / m. Vim hais tias txoj kev tsheb ciav hlau dav dav thiab lub vev xaib loj hlob nrog kev tsheb nqaj hlau loj, cov ntiv taw ntiv taw zoo, lub hauv paus phaj lub rooj zaum thiab qhov ntev ntawm lub caij nplooj ntoos hlav fastening yuav tsum ua raws li cov lus qhia kev tsheb nqaj hlau, tsis yog lub npe ntsuas.
Hom Fastening Spring Sizes
Rau txoj kev tsheb ciav hlau pom ntawm 1067 hli thiab 1000 hli kab, fastening springs poob rau hauv lub hnab ntawv me me:
| Rail seem | Hom clip bar txoj kab uas hla | Clip tag nrho ntev | Chav ntsuas hnyav | ntiv taw load range |
|---|---|---|---|---|
| 18-30 kg / m (lub teeb kab) | 10-11 hli | Txog 100-120 mm | 0.15-0.25 kg | 3-5 kN |
| 30-40 kg / m (kev sib xyaw ua ke) | 12 hli | Txog 110-130 mm | 0.25-0.35 kg | 4-6 kN |
| 40-57 kg/m (lub ntsiab thiab hnyav-haul) | 13 hli | Txog 120-140 mm | 0.35-0.50 kg | 6-8 KN |
Cov duab yog cov hnab ntawv zoo rau lub caij nplooj ntoos hlav- hom fastenings; lub caij nyoog ntev thiab ntiv taw load yuav tsum los ntawm lub fastening system kos duab rau kab, vim hais tias lub hauv paus phaj geometry thiab pw tsaug zog lub xub pwg txoj hauj lwm txawv ntawm manufacturers.
Khoom siv thiab tsim kev xav
Springs rau cov ntsuas no siv tib lub caij nplooj ntoos hlav steel qib raws li tus qauv -gauge clips: 60Si2MnA los yog 60Si2CrA ib GB/T 1222, los yog 38Si7 ib EN 10089 rau export systems, tshav kub kho rau ib tug hardness nyob ib ncig ntawm HRC 40-47. Ntawm nqaim- ntsuas kab nrog nruj nkhaus thiab nquag nres, qhov clip tau nthuav tawm ntau dua rau cov quab yuam ntawm ib tuj ntawm qag load, yog li lub kaw lus fastening feem ntau xaiv nrog cov ntiv taw siab dua me ntsis thiab lub ncoo uas ntxiv damping. Qhov twg cov kab khiav los ntawm qhov kub thiab txias, cov ntaub ntawv pov thawj yuav tsum suav nrog qhov ntsuas kub ntawm qhov ntsuas kub kom cov clip tsis tig nkig rau lub caij ntuj no.
Kev xaiv thiab pov thawj
Txhawm rau hais kom nrawm nrawm rau 1067 hli lossis 1000 hli kab, pib los ntawm cov kab tsheb ciav hlau kos duab thiab hom pw tsaug zog, tom qab ntawd paub meej tias tsev neeg fastening system, thiab tsuas yog tom qab ntawd nyeem cov clip qhov ntev thiab ntiv taw load los ntawm qhov system kos duab. Thov daim ntawv ceeb toom clamping quab yuam ntsuas raws EN 13146-7, rov ua dua-loading qaug zog daim ntawv qhia raws li EN 13146-5, thiab cov ntaub ntawv pov thawj. Vim hais tias nqaim-gauge systems feem ntau nkag rau hauv cov khoom me me, nug tus neeg muag khoom kom paub meej tias cov ntiv taw hnyav thiab qhov kev teeb tsa deflection; ob qho tib si yuav tsum phim daim duab, los yog clip yuav poob tuav los yog overstressed.
FAQ
Q1: Puas yog 1067 mm thiab 1000 mm railways siv qhov sib txawv fastening springs?Tsis tau; lub caij nplooj ntoos hlav yog qhov loj ntawm rail seem thiab qag load. Zoo sib xws rail ntawm ob lub ntsuas yuav siv cov clips zoo sib xws, thiab tsuas yog kos duab txiav txim siab.
Q2: Cov kab tsheb ciav hlau dab tsi yog qhov nqaim ntawm - ntsuas kab?18-30 kg/m ntawm cov ceg teeb, 37-50 kg/m ntawm cov kab loj, thiab mus txog 57 kg/m ntawm hnyav-haul nqaim-gauge txoj kev.
