Railway Anchor Bolt

Thauj tog rau nkoj bolts raug ntsia rau hauv ua ntej -drilled qhov nyob rau hauv lub sleepers. Los ntawm cov xov siab - lub zog muaj zog, lub caij nplooj ntoos hlav ntxhua khaub ncaws, lub tshuab ntxhua khaub ncaws, thiab cov txiv ntoo xauv, lawv kaw lub tsheb ciav hlau mus rau tus neeg pw tsaug zog, uas muaj lub zog ntawm 100–150 kN longitudinal shear force tsim thaum ib qho - qag 25–30 t freight tsheb nres. Tsis zoo li cov bolts tig tawm, lawv lub neej tsim yuav tsum yog 30 xyoo txij nkawm-dawb, cuam tshuam ncaj qha rau kev taug kev du thiab kev nyab xeeb ntawm tsheb ciav hlau.

Tus nqi tshwj xeeb txawv nyob ntawm cov khoom siv, txheej txheem, thiab kev thauj khoom	Lub zog Performance index uas lub ntsia liaj qhov rooj tuaj yeem tiv taus qhov siab tshaj plaws yam tsis muaj kev qaug zog tsis ua haujlwm nyob rau hauv kev hloov pauv. Tus nqi tshwj xeeb txawv nyob ntawm cov khoom siv, txheej txheem, thiab kev thauj khoom

 

 

Double anti-loosening protection: The head has 30° anti-loosening teeth on the bottom surface, which, when used with a nylon insert lock nut, provides an anti-loosening torque of >600 N·m.

Kev them nyiaj eccentricity: T- lub taub hau tsim tso cai rau 1:20 taper kom haum rau qhov sib txawv ntawm lub kaum sab xis ntawm lub qhov rooj pw tsaug zog.

Kev cuam tshuam kev thauj mus los: Kev cuam tshuam ntawm ntu tus pas nrig thiab lub qhov ua vaj tse yog 0.08-0.12 hli, uas, thaum siv tshuaj anchoring nplaum los yog lub tes tsho nthuav dav, muab kev rub tawm - tawm ntawm 80 kN.

Kev txheeb xyuas thiab traceability: Lub taub hau yog laser -engraved nrog cov chaw tsim khoom lub cim + batch tooj + xyoo, txhawb nqa tag nrho lub neej traceability.

Kev txhim kho kev tiv thaiv corrosion: zinc- txhuas- magnesium txheej muaj tus kheej - kho, ncua ntsev tsuag lub neej ntawm 25 xyoo mus rau 35 xyoo.

Railway Anchor Bolts yog los tiv thaiv - creep anchors rau kev tsheb ciav hlau. Lawv cuam tshuam haum, tiv thaiv -loosing hniav, thiab siab shear resistance tsim kom ntseeg tau tias txoj kev tsheb nqaj hlau tseem ruaj khov nyob rau hauv qhov chaw txawm tias tom qab ntau lab ntawm kev cuam tshuam ntawm braking. Xaiv cov ntsia hlau tsis raug tuaj yeem ua rau geometric deformation ntawm txoj kev tsheb ciav hlau; xaiv cov khoom tsim nyog tuaj yeem ua kom paub tseeb 30 xyoo ntawm kev saib xyuas- ua haujlwm dawb, lav kev nyab xeeb ntawm kev ua haujlwm ntau -billion dollar railway network.
