2 Hom Railway Spike rau Rail Fastening

Lub luag hauj lwm ntawm railway spike

Rail spikes yog cov fasteners uas tuav txoj kev tsheb ciav hlau - lossis lub hauv paus hauv qab ntawm txoj kev tsheb ciav hlau - mus rau tus neeg pw tsaug zog. Lawv lub luag haujlwm tseem ceeb yog ua kom txoj kev khiav hauv qhov ntsuas los ntawm kev tiv thaiv kev txav mus los ntawm txoj kev tsheb ciav hlau, thaum tseem nqa ib feem ntawm txoj kab ntsug thiab qhov ntev. Spikes yog tsim nyob rau hauv siab ntim, yog ceev rau nruab thiab yog ib tug ntawm cov hiob, feem ntau txhim khu kev qha ntsiab ntawm fastening system.

Hom 1: Dog spike (txiav spike)

Tus dev spike, tseem hu ua ntu ntu ntu, yog lub xwmfab loj- ntu ntsia hlau nrog lub taub hau tiaj tus thiab lub chisel lossis qhov taw tes. Nws yog tsav mus rau hauv ib tug ntoo sleeper nrog ib tug spike rauj los yog neeg kho tshuab tsav tsheb thiab tuav tog twg los rail ko taw ncaj qha los yog ib tug baseplate. Lub npoo taw tes tshem tawm cov ntoo fibers, thiab cov square shank tuav lawv kom cov ntsia hlau tiv thaiv raug rub tawm los ntawm kev tsheb nqaj hlau. Dog spikes yog kev lag luam, txhim kho sai heev, thiab yog tus qauv kho ntawm cov ntoo - pw tsaug zog khiav hauv ntau thaj tsam.

Hom 2: ntsia hlau ntsia hlau (rail ntsia hlau ntsia hlau)

Cov ntsia hlau ntsia hlau yog ib txoj hlua khi nrog cov xov coarse helical thiab lub taub hau uas lees txais lub qhov (socket) los yog ciaj ntswj. Nws yog screwed rau hauv lub sleeper, uas muab ob yam zoo dua ib tug tsav spike: siab tuav lub zog tiv thaiv uplift thiab lateral zog, thiab huv si tshem tawm cov cuab yeej, yog li ntawd lub sleeper tsis puas thaum lub spike yog tshem tawm. Screw spikes yog siv rau cov ntoo sleepers thiab, nrog ib tug yas dowel los yog insulator, nyob rau hauv qhob pw tsaug zog, qhov twg lawv thauj tog rau nkoj baseplates ntawm elastic fastening systems.

Cov ntaub ntawv thiab tiav

Spikes yog forged los yog machined los ntawm carbon steel. Cov qib txheem yog siv rau cov kev pabcuam dav dav, thaum tshav kub- kho siab - lub zog yog muab rau qhov uas tuav lub zog yuav tsum ua kom siab tshaj plaws. Kev kho deg yog xaiv rau ib puag ncig: dawb oiled rau qhuav inland kev pab cuam, galvanized rau ntug hiav txwv dej, tunnel thiab tropical kab, thiab pleev xim rau qhov chaw tiv thaiv corrosion yuav tsum tau pom ntawm kev soj ntsuam. Dimensional kam rau ua thiab straightness tseem ceeb vim hais tias ib tug off-square spike installs tsis zoo thiab ua rau cov neeg tsaug zog.

Cov lus qhia xaiv

Kev kho ncaj qha ntawm kev tsheb ciav hlau mus rau cov ntoo pw tsaug zog: dev spike yog qhov kev xaiv tus qauv kev lag luam.

Baseplate ntawm ntoo sleeper nrog nquag tshem tawm cycles: ntsia hlau spike preserves tus sleeper.

Qhob pw tsaug zog: ntsia hlau spike nrog yas dowel, raws li siv nyob rau hauv elastic fastening systems.

Corrosive ib puag ncig: qhia meej galvanized lossis pleev xim tiav.

Cov lus nug uas nquag nug

Dab tsi yog qhov txawv ntawm tus dev spike thiab ib tug ntsia hlau ntsia hlau?

Ib tug aub spike yog ib tug square-section ntsia thawv uas tau tsav mus rau hauv lub pw tsaug zog; Cov ntsia hlau ntsia hlau muaj cov xov ntxhib thiab ntsia hlau rau hauv. Cov ntsia hlau ntsia hlau muab lub zog tuav ntau dua thiab tuaj yeem tshem tawm kom huv, thaum tus dev spike yog ceev dua thiab pheej yig dua rau nruab.

Cov ntsia hlau spikes puas tuaj yeem siv rau hauv cov ntoo pw?

Yog lawm. Screw spikes ua haujlwm zoo hauv cov ntoo thiab feem ntau nyiam qhov twg cov fasteners yuav raug tshem tawm thiab rov-tsav, vim hais tias cov xov rub tawm kom huv si tsis txhob rhuav cov ntoo.

Vim li cas cov yas dowels siv nrog cov ntsia hlau spikes hauv cov pob zeb pw?

Lub dowel yog nrum los yog drilled rau hauv lub pob zeb thiab muab cov xov anchorage rau cov ntsia hlau ntsia hlau loj. Nyob rau hauv insulated fastenings nws kuj hluav taws xob cais cov tsheb ciav hlau los ntawm lub sleeper.

Cov dev spikes raug tshem tawm li cas?

Nrog ib tug spike puller los yog claw, los ntawm lifting nyob rau hauv lub taub hau. Ntawm cov ntoo pw tsaug zog lub qhov feem ntau yog sau los yog rov ua dua -spiked nrog ib seem loj dua los tuav tuav.

Dab tsi ua tiav tiv thaiv spikes los ntawm corrosion?

Feem ntau cov tiav yog cov roj pleev xim, dub oxide, zinc plating, kub dip galvanizing thiab pleev xim. Galvanizing raug pom zoo rau cov ntug dej hiav txwv, qhov thiab siab - cov av noo.

Puas yog spikes ua haujlwm nyob rau hauv elastic fastening systems?

Tsis zoo li tus thawj clamp. Elastic fastenings cia siab rau lub caij nplooj ntoos hlav clips rau lub zog tuav; ntsia hlau spikes kho lub baseplate rau lub sleeper thiab ua hauj lwm nrog rau cov clip system.
