Kub Dip Galvanized Ob Lub Taub Hau Screw Spike: Qib, Khoom thiab Daim Ntawv Thov
Oct 23, 2025
Dab tsi yog ob lub taub hau ntsia hlau ntsia hlau loj
Lub railway ntsia hlau ntsia hlau yog ib qho fastener siv los kho steel rails rau railway sleepers. Tsis zoo li tus dev spike, cov ntsia hlau ntsia hlau muaj ib lub shank uas embeds rau hauv cov khoom siv pw tsaug zog, feem ntau yog ntoo los yog rau hauv ib lub dowel nyob rau hauv ib lub pob zeb, muab kev ruaj ntseg thiab ruaj khov. Lub taub hau ntsia hlau ob npaug ntxiv rau lub taub hau thib ob hauv qab lub taub hau loj kom tus ntsia hlau loj tuaj yeem clamp lub khi phaj lossis lub hauv paus phaj los ntawm ob sab ntawm txoj hlua taw, faib cov clamping quab yuam thiab nce rub - tawm tsam.
Qhov ob- lub taub hau tsim yog siv qhov uas yuav tsum tau tuav lub tsheb ciav hlau, lub sleeper thiab khi phaj nruj nreem ua ke, piv txwv li rau cov pob zeb pw taug kev nrog ib tug baseplate system. Nws absorbs lub longitudinal thiab lateral kev co ntawm lub tsheb ciav hlau kev khiav hauj lwm thiab ua rau cov khiav geometry ruaj khov nyob rau hauv ib tug ntev kev pab cuam lub neej.
Qhov ntau thiab tsawg
| Parameter | Tus nqi |
|---|---|
| Qhov loj me | 23 x 174 mm |
| Cov chav kawm vaj tse | 4.6, 4.8, 5.6, 5.8, 8.8, 10.9 |
| Cov khoom nyoos | Q235, 35#, 45# thiab siab dua - lub zog steels |
| Kev kho saum npoo | Plain (roj), bluing / oxide dub, zinc, kub-dip galvanized (HDG), ciab, bitumen, Dacromet, sherardizing |
| Standard siv | ISO 898-1, UIC 864-1, NF F500-50 |
Kub-dip galvanizing yog qhov zoo tshaj plaws rau qhov chaw sab nraum zoov thiab ntub dej vim tias cov zinc txheej tiv thaiv cov xov thiab lub shank tiv thaiv corrosion rau ntau xyoo. Qhov twg cov ntsia hlau ntsia rau hauv cov yas dowel, lub txheej kuj muab kev tswj kom haum nrog cov dowel threads.
Mechanical zog los ntawm qib

| Elongation | Ntau dua lossis sib npaug li 22% | Ntau dua lossis sib npaug li 20% | Ntau dua lossis sib npaug li 12% | Ntau dua lossis sib npaug li 9% |
| Txias khoov | 90℃tsis tawg | |||
Cov qib raug xaiv raws li qeb: qib 4.6 thiab 5.6 spikes npog tus qauv thiab lub teeb- lub luag haujlwm fastenings, qib 8.8 yog teev rau nruab nrab thiab hnyav- lub luag haujlwm khiav, thiab qib 10.9 yog siv qhov kev tsim fastening xav tau lub zog siab tshaj plaws. Kev txwv cov cuab yeej cuab tam ua raws li cov cai ntawm ISO 898-1 rau fasteners.
Kev ua raws cai
Kev tsim thiab tsim khoom ntawm railway ntsia hlau spikes yuav tsum ua raws li cov qauv siv hauv lub tebchaws thiab thoob ntiaj teb, uas txhais cov khoom siv, cov khoom siv kho tshuab, qhov ntev ntev thiab tiv thaiv kev tiv thaiv - kho corrosion. Cov qauv siv rau tsev neeg cov khoom no suav nrog ISO 898-1 (cov cuab yeej cuab tam ntawm fasteners), UIC 864-1 (sleeper screws for railway fastening) thiab NF F500-50 (Fabkis railway fastening requirements). Kev qhia spikes tawm tsam tus qauv lees paub ua kom muaj kev nyab xeeb thiab ruaj khov ntawm txoj kev taug qab thiab txhawb nqa cov ntaub ntawv zoo tshaj plaws ntawm kev xa khoom.
Hom hom hauv Ss thiab V series
| Hom series | Hom npe |
|---|---|
| Ss series (sleeper ntsia hlau) | Ss5-150, Ss8-140, Ss8-150, Ss8-160, Ss23-160, Ss25-165, Ss35-161 |
| V series (variable xov) | V20-135, V23-115, V23-135, V23-155, V23-215, V26-115 |
Lub Ss series ua raws li qhov kev siv dav dav siv thoob plaws European thiab Esxias tes hauj lwm, thaum V series xaiv qhov sib txawv - xov screws rau pob zeb pw dowels. Hom sab nraum cov koob no tuaj yeem tsim rau cov neeg siv khoom kos duab.
Cov lus nug nquag
Dab tsi yog qhov zoo ntawm ob lub taub hau tsim?
Lub taub hau ob chav muab clamping quab yuam ntawm ob sab ntawm lub khi phaj los yog baseplate, tsim kom muaj kev sib txuas ntawm cov tsheb ciav hlau, pw tsaug zog thiab phaj. Qhov no ua rau kom rub- tawm qhov tsis kam thiab txhim kho qhov ruaj khov ntawm qhov nrawm nrawm hauv qhov hnyav.
Qib twg yog xav tau rau siab - ceev lossis hnyav thauj khoom?
Qib 8.8 lossis 10.9 spikes tau teev tseg qhov twg qhov fastening yuav tsum nqa ntau dua loads, xws li mainline, siab - ceev thiab hnyav thauj khoom. Qib 4.6 thiab 5.6 yog txaus rau cov pa thiab lub teeb -function fastenings.
Vim li cas ho kub -dip galvanizing pom zoo?
Kub-dip galvanizing ua rau cov zinc txheej tuab uas tiv thaiv qhov tsis zoo ntawm corrosion nyob rau hauv qhov chaw ntub dej, ntug hiav txwv dej thiab tshuaj lom neeg, ua kom lub neej ntev kev pab cuam ntawm fastening thiab txo tus nqi txij nkawm.
Cov ntsia hlau spikes puas tuaj yeem siv nrog cov pob zeb pw tsaug zog?
Yog lawm. Qhob pw tsaug zog yog cam khwb cia nrog yas los yog steel dowels, thiab lub spikes yog screwed rau hauv lub dowel. Lub dowel muab cov xov kev sib koom tes thiab cov ntsia hlau loj tuaj yeem raug tshem tawm thiab hloov thaum lub caij tsheb ciav hlau.
Yuav ua li cas cov qauv siv rau cov ntsia hlau spike zoo?
Cov ntaub ntawv muaj feem cuam tshuam suav nrog ISO 898-1 rau cov khoom siv kho tshuab, UIC 864-1 rau cov ntsia hlau pw tsaug zog, thiab NF F500-50 rau Fabkis txoj kev tsheb ciav hlau fastening. Lwm cov qauv hauv tebchaws tuaj yeem siv tau raws li kev thov.
Puas muaj kev cai loj?
Yog lawm. Spikes tuaj yeem tsim rau tus neeg siv khoom qhov ntev thiab kos duab, nrog rau qib uas xav tau, cov khoom siv thiab kev kho deg, rau ob qho tib si tus qauv thiab tsis yog - daim ntawv thov txheem.
