Dab tsi yog qhov sib txuam fasteners rau GOST P65 rails?

Kom ruaj ntseg GOSTP65 (R65) rails nruj nreem rau txoj kab tsheb ciav hlau, cov kws tsim khoom siv tshwj xeeb, hnyav - lub luag haujlwm fastening systems. Vim tias P65 profile yog qhov hnyav -chav tsheb ciav hlau (64,72 kg/m²) tsim los rau siab - cov kab loj loj thiab cov khoom thauj hnyav, cov khoom sib txuam no yuav tsum muab lub zog clamping loj (ntiv taw load), tiv taus qhov ntev ntawm txoj kev tsheb ciav hlau nkag, thiab nqus tau siab heev - zaus vibrations.

Qhov sib txuam fasteners rau P65 rails yog categorized los ntawm txoj kev tsim lub moj khaum thiab hom ntawmcov neeg tsaug zog(cov) siv.

1.Concrete Sleeper Fastening Systems

Hauv kev tsim kho tshiab niaj hnub no, cov pob zeb pw tsaug zog yog tus qauv rau P65 tes hauj lwm. Lawv vam khom los yog elastic fastening sib dhos rau thauj tog rau nkoj.

KB Fastening System (Separate Rigid Assembly)

KB (КБ-65) system yog qhov feem ntau muaj keeb kwm yav dhau los thiab siv dav siv los ua ke rau P65 rails ntawm cov pob zeb pw. Nws yog "sib cais" hom fastener, lub ntsiab lus ntawm txoj kev tsheb ciav hlau yog clamped rau khi phaj, thiab khi phaj yog bolted rau tus neeg pw tsaug zog ntawm nws tus kheej.

kb fasteners system

Tie Phaj (Pодкладка):Siv KB-65 steel khi phaj, uas muaj lub rooj zaum ua ntej lub kaum sab xis (1 : 20 rail inclination) kom phim cov tsheb ciav hlau log.

Terminal Bolts & Clips:Lub tsheb ciav hlau ko taw tau ruaj ntseg rau lub khi phaj siv cov hlua khi steel (terminals) thiab M22 × 75 davhlau ya nyob twg bolts.

Anchor Bolts:Tag nrho cov hlua khi yog khi rau hauv lub pob zeb pw siv M22 × 175 thauj tog rau nkoj bolts screwing rau hauv cov dowels.

Rwb thaiv tsev &Pads:Siv cov roj hmab los yog polyurethane textolite pads hauv qab ntawm txoj kev tsheb ciav hlau thiab hauv qab lub phaj khi los muab cov hluav taws xob cais tawm rau cov khoom siv hluav taws xob thiab ua kom muaj kev vibrations.

ZhBR thiab ARS Systems (Direct Elastic Assemblies)

Txhawm rau txo cov khoom siv siab suav thiab kev saib xyuas nyiaj siv ua haujlwm ntawm KB system, niaj hnub P65 lem nce ntxiv rau kev siv ncaj qha, boltless elastic fasteners.

ZBR (ЖБР-65):Lub caij nplooj ntoos hlav-clip sib dhos uas tshem tawm cov hlau khi hnyav. P65 kev tsheb nqaj hlau zaum ncaj qha rau ntawm cov roj hmab ncoo ntawm lub pob zeb pw hauv hnab tshos thiab yog clamped los ntawm siab - lub zog caij nplooj ntoos hlav steel clips tuav los ntawm ntsug bolts.

ZhBR fasteners system

ARS (АРС-4):Ib qho kev ua haujlwm siab, tsis muaj boltless thauj tog rau nkoj- hom fastening system. Nws siv lub thauj tog rau nkoj ncaj qha mus rau hauv lub pob zeb pw tsaug zog. Lub R65 kev tsheb ciav hlau tau ruaj ntseg los ntawm kev tsav tsheb elastic omega- zoo li lub caij nplooj ntoos hlav clip rau hauv lub thauj tog rau nkoj. Nws ua rau txo qis txij nkawm txij li tsis muaj threaded bolts kom loosen lossis lubricate.

2. Ntoo Sleeper Fastening Systems

Rau cov kab hauv cheeb tsam, hloov cov yards, lossis cov nkhaus nkhaus uas cov ntoo sib txuas yog nyiam rau lawv cov elasticity, cov khoom siv sib txawv yog xav tau.

DO Fastening System (Sib xyaw Clamping)DO (ДО-65) system yog tus qauv sib txuam teeb tsa rau P65 rails ntawm cov ntoo pw.
Tie Phaj:Siv D65 (Д-65) steel khi phaj.

Rail Spikes (Костыли):Relies rau tus qauv 16 × 16 × 165 mm railway khiav spikes. Lub kaw lus hu ua "sib xyaw" vim tias qee qhov spikes clamp lub tsheb ciav hlau ko taw ncaj qha mus rau ntoo, thaum lwm cov spikes tsuas yog thauj tog rau nkoj khi phaj kom tiv thaiv kev hloov pauv.

KD Fastening System (Sib cais Clamping)Zoo ib yam li KB system tab sis optimized rau ntoo. Nws siv KD-65 (КД-65) khi phaj. Lub khi phaj yog ntsia hlau rau hauv cov ntoo pw nrog hnyav-lub luag hauj lwm lag screws (ntsia hlau spikes), thiab P65 rail ko taw yog cais clamped rau lub phaj nrog davhlau ya nyob twg bolts thiab clips. Qhov no tiv thaiv cov ntoo khi los ntawm kev tawg ntxov ntxov los ntawm kev vibrations spikes.

3. Cov khoom siv sib txuas sib txuas (Fishplates)

Thaum P65 rails tsis welded rau hauv cov hlua txuas ntxiv thiab xav tau cov khoom siv kho tshuab, lawv siv cov qauv sib koom ua ke:

Ntses phaj:Tswj los ntawmTIAB SA 8193, cov no yog cov hlau hnyav sib koom ua ke tsim tshwj xeeb kom haum rau lub kaum ntse ntse nuv ntses (qhov chaw nruab nrab ntawm lub taub hau thiab lub hauv paus) ntawm P65 profile. Lawv muaj nyob rau hauv 4-qhov lossis 6-qhov kev teeb tsa.

rail joint

Track Bolts:Siab -lub zogM24 × 150 boltshla lub vev xaib kev tsheb ciav hlau thiab qhov chaw ntses ntses, ruaj ntseg los ntawm cov txiv ntoo hnyav hex thiab ib zaug - tig lub caij nplooj ntoos hlav ntxhua khaub ncaws (GOST 19115) kom tswj kev nro tiv thaiv lub log tsis tu ncua.

Cov lus nug nquag

Vim li cas P65 rail web feature alternating round thiab oval bolt qhov?

Lub alternating puag ncig thiab oval 34 hli qhov tso cai rau txoj kev tsheb ciav hlau nthuav dav thiab cog lus ib txwm nyob rau lub caij ntuj sov viav vias. Lub oval tsim muab kab rov tav tshem tawm kom lub vev xaib kev tsheb nqaj hlau tuaj yeem swb yam tsis muaj kev puas tsuaj shearing stresses ncaj qha rau M24 sib koom bolts.

KB-65 fasteners puas siv tau rau tus qauv European UIC60 lossis 60E1 rails?

Tsis yog. Lub KB-65 khi phaj thiab nruj clips yog engineered kom haum rau 150 mm puag flange ntawm P65 rail. European UIC60 kev tsheb nqaj hlau nta qhov dav 150 hli puag tab sis lub kaum ntse ntse sib txawv thiab tag nrho qhov siab (172 mm vs . 180 mm), txhais tau tias cov KB nkig nruj yuav tsis zaum yaug lossis muab lub zog tuav.

Lub luag haujlwm ntawm CP-328 roj hmab ncoo hauv KB-65 yog dab tsi?

Lub CP-328 ncoo tau muab tso rau hauv qab lub hauv paus steel ntawm cov pob zeb pw. Nws ua raws li kev poob siab absorber los tiv thaiv cov pob zeb tsis sib haum los ntawm kev tawg nyob rau hauv high-frequency rail vibrations thiab muab hluav taws xob tseem ceeb los tiv thaiv cov teeb liab tam sim no xau rau hauv av.

Ntev npaum li cas cov clip bolts ntawm KB-65 yuav tsum tau kuaj xyuas lub zog?

Nyob rau hauv siab -cov kab loj loj thauj khoom, theem torque (engineered mus rau 150-200 Nm) raug tshuaj xyuas ib nrab-ib xyoos ib zaug siv cov tsheb khiav tsis siv neeg los yog phau ntawv torque wrenches los tiv thaiv bolt loosening ntawm cyclic loading.

Puas yog cov yas dowels xav tau hauv cov pob zeb ua haujlwm rau ZhBR-65 fasteners?

Yog lawm, siab -lub zog polyamide yas dowels yog embedded ncaj qha mus rau hauv lub pob zeb pw tsaug zog thaum lub Hoobkas casting. Cov dowels no muab cov khoom ruaj ntseg thauj tog rau nkoj rau qhov hnyav kho screws thiab cais cov hlau fastening Cheebtsam hluav taws xob.
