Txhais thiab keeb kwm ntawm Modular Fastening System
Lub modular rail fastening system yog cov txheej txheem sib dhos ntawm cov khoom sib cais uas ua haujlwm ua ke los tuav txoj kev tsheb ciav hlau mus rau lub txaj pw lossis taug kev slab. Cov txheej txheem tseem ceeb muaj xws li kev tsheb ciav hlau clips, siab - lub zog bolts, xauv lub tshuab ntxhua khaub ncaws, insulated gauge blocks thiab ua ntej - lub tes tsho embedded. Txhua ntu muaj cov haujlwm uas tau hais tseg: rail clips muab lub zog clamping, bolts xa cov khoom thauj thiab tiv thaiv kom tsis txhob xoob los ntawm kev xauv lub tshuab ntxhua khaub ncaws, insulated gauge blocks tswj ntsuas ntsuas thaum muab hluav taws xob rwb thaiv tsev, thiab ua ntej - lub tes tsho embedded muab lub bolt ib qho chaw thauj tog rau nkoj meej hauv cov pw tsaug zog lossis slab. Vim tias txhua qhov sib xyaw ua ke yog qhov sib txawv rau tus qauv kev sib txuas, ib tus neeg tuaj yeem hloov pauv yam tsis tau rhuav tshem tag nrho cov kab ke, uas yog lub hauv paus kom zoo dua ntawm txoj hauv kev modular.
Component Functions thiab Hom Specifications
| Cheebtsam | Muaj nuj nqi | Hom specification |
|---|---|---|
| Rail clip | Muab clamping quab yuam los tuav lub tsheb ciav hlau ko taw | Hom I, II lossis V clip xaiv los ntawm hom kev tsheb ciav hlau thiab chav thauj khoom |
| Siab - lub zog bolt | Load kis tau tus mob thiab preload | Qib 8.8 lossis siab dua; M20 lossis M24 feem ntau |
| Xauv lub tshuab ntxhua khaub ncaws | Tiv thaiv kev co -induced loosening | Caij nplooj ntoos hlav los yog serrated hom matched bolt |
| Insulated gauge thaiv | Tswj ntsuas ntsuas thiab muab rwb thaiv tsev | iav-fiber reinforced nylon; 8-20mm thickness ntau |
| Ua ntej- lub tes tsho embedded | Thauj tog rau nkoj taw tes rau lub bolt nyob rau hauv pw tsaug zog los yog slab | Sab hauv txoj kab uas hla sib tw rau bolt; cam khwb cia-in los yog glued-in |
Nyob rau ntawm txoj kab ntawm 50, 60 thiab 75 kg / m, qhov ntsuas thaiv qhov tuab yog hloov kho nyob rau hauv 8-20 mm ntau los tuav ntsuas qhov sib txawv kom tsawg dua lossis sib npaug li ± 1 hli. Kev xaiv clip ua raws li cov chav kawm ntawm cov kab: lub teeb- cov kab thauj khoom siv cov hlua khi nrog lub zog clamping Ntau dua lossis sib npaug li 6 kN, thaum hnyav - cov kab yuav tsum Ntau dua lossis sib npaug li 20 kN. Lub ntsia liaj qhov rooj ntev yog sib npaug rau qhov siab qhov siab thiab pw tsaug zog thickness kom 3-5 xov lem nyob twj ywm raug tom qab zawm.
Kev kho kom haum rau hom kev sib txawv
| Hom kev khiav | Kev teeb tsa | Cov ntsiab lus tseem ceeb |
|---|---|---|
| High - txoj kev tsheb ciav hlau ceev | Tsawg-kuj modular system | Ntev kuj 4 ± 1 kN; ruaj khov ntawm 350 km / h |
| Hnyav- txoj kev tsheb ciav hlau | Lub zog muaj zog, tuab clips, ntau bolts | Clamping quab yuam Ntau dua lossis sib npaug rau 25 kN |
| Kev thauj mus los hauv nroog | Shock -absorbing system nrog elastic ncoo | Kev vibration acceleration attenuation Ntau dua lossis sib npaug li 30% |
| Cov pa railway | General -lub hom phiaj system | Clamping quab yuam Ntau dua lossis sib npaug ntawm 12 kN; tus nqi nruab nrab |
Lub ntsiab yam ntxwv txawv ntawm ballastless thiab ballasted khiav yog nyob rau hauv lub tes tsho installation. Ballastless khiav siv integrally ua ntej- lub tes tsho embedded cam khwb cia rau hauv lub slab, thaum ballasted khiav adapts lub tes tsho mus rau lub reserved qhov ntawm cov pob zeb pw. Ntawm cov ntu nkhaus, cov hlua txuas ntxiv rau ntawm cov tsheb ciav hlau sab nrauv ua rau muaj kev tiv thaiv sab nraud tiv thaiv kev xaav centrifugal.
Installation txheej txheem thiab Torque Control
Kev teeb tsa ua raws li qhov chaw nyob - qhov chaw - nrawm nrawm. Ua ntej sib dhos, txhua yam khoom raug tshuaj xyuas: clips yuav tsum tsis muaj kab nrib pleb, bolts tsis muaj xeb, thiab ntsuas qhov thaiv tsis raug. Ua ntej- lub tes tsho hauv qab yog ntxuav nrog cov cua compressed kom cov plua plav thiab cov khib nyiab tsis tuaj yeem cuam tshuam rau lub rooj zaum. Lub ntsuas qhov ntsuas tau haum rau lub vev xaib kev tsheb nqaj hlau, qhov clip tau muab tso rau, thiab lub ntsia liaj qhov rooj yog nruj nrog lub torque ciaj ntswj mus rau tus qauv tus nqi: qhov kawg nruj torque Ntau dua los yog sib npaug rau 400 N·m rau M20 bolts thiab Ntau dua los yog sib npaug rau 600 N·m rau M24 bolts. Ob leeg nyob rau hauv - thiab tshaj - torque puas lub rooj sib txoos, yog li ib tug calibrated ciaj ntswj yog yuav tsum tau. Tom qab nruj, qhov kev lees paub yog clamping quab yuam sib txawv Tsawg dua lossis sib npaug rau ± 2 kN thiab ntsuas qhov sib txawv tsawg dua lossis sib npaug li ± 1 hli.
Kev Kho Lub Tswv Yim thiab Kev Pabcuam Lub Neej
Cov qauv tsim qauv tso cai rau kev saib xyuas: lub kaw lus puas, thaiv lossis ntsia liaj qhov rooj yog hloov ib tus zuj zus, txiav lub sijhawm txij nkawm los ntawm ntau dua 50 feem pua piv nrog tag nrho disassembly. Standardized qhov chaw khaws cov khoom seem- cov khoom muag me me thiab sib hloov tau. Lub xauv lub tshuab ntxhua khaub ncaws thiab siab - lub zog bolt sib xyaw ua ke txo qis zaus, ncua lub sijhawm txij nkawm mus rau 6 lub hlis ntawm cov kab hnyav -cov kab thiab 1 xyoo ntawm cov pa tsheb ciav hlau. Insulated gauge blocks nyob rau hauv hnav- iav resistant-fiber reinforced nylon muaj kev pab cuam lub neej ntawm 8-10 xyoo, thiab cov cuab yeej tshwj xeeb tso cai rau sai sai ntawm - qhov chaw kuaj xyuas ntawm clamping quab yuam thiab ntsia liaj qhov rooj torque kom cov teeb meem raug ntes ua ntej lawv cuam tshuam kev khiav hauj lwm.
Cov lus nug nquag
Cov khoom siv dab tsi ua rau lub tshuab ua kom nrawm nrawm?
Cov txheej txheem txheej txheem yog rail clips, siab - lub zog bolts, xauv lub tshuab ntxhua khaub ncaws, insulated gauge blocks thiab ua ntej - lub tes tsho embedded. Txhua yam yog tsim los rau tus qauv interfaces yog li txhua tus tuaj yeem hloov pauv tus kheej.
Lub kaw lus hloov mus li cas rau 50, 60 thiab 75 kg / m rails?
Kev kho kom haum yog ua tiav los ntawm kev hloov lub ntsuas ntsuas qhov tuab (8-20 hli) kom haum rau txoj kab tsheb ciav hlau dav dav thiab xaiv cov clip hom thiab clamping quab yuam chav kawm rau cov tsheb ciav hlau qhov hnyav thiab cov chav kawm thauj khoom.
Vim li cas cov tshuab ntxhua khaub ncaws siv nrog siab - lub zog bolts?
Dynamic loading los ntawm cov tsheb ciav hlau hla dhau mus rau unscrew bolts dhau sijhawm. Lub xauv lub tshuab ntxhua khaub ncaws tuav qhov nro nyob hauv qhov sib koom ua ke thiab tiv thaiv kev co -induced loosening, ncua lub sijhawm txij nkawm.
Dab tsi torque yuav tsum tau rau M20 thiab M24 bolts?
Qhov kawg nruj torque yog ntau dua los yog sib npaug rau 400 N·m rau M20 thiab ntau dua los yog sib npaug rau 600 N·m rau M24 bolts. Lub calibrated torque wrench yuav tsum tau siv, thiab torque yuav tsum tau rov ua dua - xyuas raws li lub sijhawm teem tseg.
Yuav ua li cas yog lub kaw lus ntsia ntawm ballastless tiv thaiv ballasted khiav?
Ntawm ballastless khiav lub tes tsho yog ua ntej- embedded integrally nyob rau hauv lub slab thaum lub sij hawm casting; ntawm ballasted khiav lawv tau yoog rau cov qhov tshwj xeeb hauv cov pob zeb ua haujlwm. Qhov seem installation ib ntus yog tib yam.
Lub sijhawm tu ncua siv li cas rau hnyav- cov kab thiab cov kab sib xyaw ua ke?
Hnyav- cov kab tsheb thauj khoom feem ntau yog muab kev pabcuam txhua 6 lub hlis thiab cov kev tsheb ciav hlau zoo ib yam txhua 12 lub hlis, ua tsaug rau kev xoob- tiv taus bolted tsim. Gauge blocks yog tsim rau 8-10 xyoo kev pabcuam.
