Dab tsi yog Track Fastening System muaj
Lub kaw lus fastening txhim kho txoj kev tsheb ciav hlau mus rau cov neeg pw tsaug zog lossis taug kev slab thaum tso cai rau kev txav mus los thiab kev co damping. Txhua yam khoom muaj lub luag haujlwm tau hais tseg, thiab lub kaw lus tsuas yog ua thaum txhua tus ua haujlwm ua ke.
| Cheebtsam | Lub luag haujlwm tseem ceeb |
|---|---|
| Elastic clip | Tsim clamping quab yuam los ntawm elastic buckling; kho txoj hauj lwm rail thiab absorbs kev co |
| Kauv ntsia hlau loj / ntsia hlau ntsia hlau loj | Anchors tag nrho cov sib dhos rau hauv lub txaj pw thiab muab kev txhawb nqa ntsug |
| Insulating gauge thaiv | Kho qhov ntsuas thiab muab hluav taws xob rwb thaiv tsev ntawm cov kab hluav taws xob |
| Nias phaj (rail puag phaj) | Ua haujlwm nrog cov bolts los txhim kho txoj kev tsheb ciav hlau ko taw thiab tiv thaiv kev txav mus ntev |
| Lub tshuab ntxhua khaub ncaws | Disperses ntsia liaj qhov rooj siab, tiv thaiv cov khoom nto thiab pab tswj ua ntej - nro |
| Anchor bolt | Kaw cov hlua thauj khoom ntawm clip, phaj thiab pw tsaug zog |
Yuav ua li cas cov Cheebtsam ua hauj lwm raws li ib tug system
Lub clamping quab yuam ntawm lub clip thawb lub tsheb ciav hlau ko taw tiv thaiv lub hauv paus phaj los ntawm cov insulating qhov chaw. Thaum lub tsheb ciav hlau hla, ntsug load yog hloov los ntawm lub log mus rau txoj kev tsheb ciav hlau, ces los ntawm cov ntiv taw ntiv taw thiab lub hauv paus phaj rau hauv lub txaj pw; lateral load yog resisted los ntawm gauge sab ntawm lub rooj sib txoos. Lub elastic stroke ntawm lub clip - qhov deb nws tuaj yeem deflect tsis poob quab yuam - yog dab tsi ua rau txoj kev tsheb ciav hlau txwv tsis pub dhau qhov kub thiab kev tsheb khiav. Lub kaw lus tsim nrog kev sib tw nruj ntawm clip, ncoo thiab phaj tuav ntsuas qhov zoo tshaj qhov tawv, tsis muaj zog.
Kev ua tau zoo yuav tsum tau ua los ntawm Railway Hom
Kev khiav hauj lwm ib puag ncig teev cov specification. Cov kab ib txwm optimize tus nqi; siab - cov kab ceev ua kom zoo zog ruaj khov thiab rwb thaiv tsev; hnyav- cov kab tsheb txhim kho lub zog thiab hnav tsis kam.
| Hom kev tsheb ciav hlau | Clamping quab yuam | Qhov xav tau tseem ceeb |
|---|---|---|
| Ordinary railway | 8-10 KN | Yooj yim kho muaj nuj nqi, tus nqi qis, kho yooj yim |
| High - txoj kev tsheb ciav hlau ceev | Tsawg kawg yog 10 kN | Elastic stroke ntawm tsis pub tsawg tshaj 10 hli; rwb thaiv tsev muaj peev xwm tiv taus ntau dua 3 lab lub voj voog qaug zog |
| Hnyav- txoj kev tsheb ciav hlau | 12-15 kN | Siab - lub zog alloy steel cov khoom tiv thaiv kev cuam tshuam thiab sab nraud ntawm cov qag loj loads |
Kev ua haujlwm qaug zog yog qhov kev tswj hwm ntawm qhov siab - cov kab ceev: kev sib xyaw ua ke ntawm kev kub ceev thiab kev vibration siab txhais tau tias txhua qhov clip, ncoo thiab insulator yuav tsum muaj sia nyob ntau lab ntawm kev sib hloov ntawm lub voj voog yam tsis poob lub zog clamping.
Rwb thaiv tsev, Loosening thiab Boltless Option
Nyob rau hauv cov hluav taws xob railways cov rails nqa cov teeb liab tam sim no, thiab lub fastening system yuav tsum tiv thaiv tam sim no los mus rau lub pw tsaug zog thiab hauv av. Lub ntsiab insulating qhov chaw yog cov insulating gauge blocks thiab insulating washers, feem ntau yog molded los ntawm siab -lub zog nylon los yog composite cov ntaub ntawv uas thaiv tam sim no conduction thaum tseem nqa txhua yam load. Yog tias rwb thaiv tsev tawg, teeb liab cuam tshuam thiab cov khoom puas tsuaj ua raws.
Loose bolts pib cov tshuaj tiv thaiv kab mob: clamping quab yuam poob, cov tsheb ciav hlau hloov mus tom qab, ntsuas qhov dav, lub log -rail kev sib txhuam nce thiab kev tsheb ciav hlau sab hnav nrawm dua. Hauv qhov xwm txheej hnyav, kev tsheb ciav hlau tuaj yeem nqa tau thiab kev pheej hmoo derailment nce ntxiv. Kev saib xyuas txhua hnub kuaj pom qhov no nrog lub zog ntsuas lub zog tiv thaiv tus qauv tsim ua ntej- nruj torque, ntxiv rau kev tshuaj xyuas qhov muag ntawm tus ntiv taw ntiv taw - lub hnub poob lossis tshem tawm qhov kawg feem ntau txhais tau hais tias lub bolts loosened.
Boltless fastening systems hloov cov bolts nrog ua ntej -cov xub pwg embedded cam khwb cia los yog molded rau hauv pw tsaug zog. Lawv tshem tawm bolt corrosion thiab txij nkawm, tuav lub ntsuas kom zoo dua thiab pom qhov seem me me deformation, uas yog vim li cas hnyav -haul thiab siab - cov kab tsheb thauj mus los nrog cov nqi kho mob siab xaiv lawv. Kev lag luam tawm - tawm yog qhov pib nqis peev ntau dua, uas yog vim li cas txoj kev tsheb ciav hlau tsis tshua siv lawv.
Saib xyuas Kev Tiv Thaiv Qhov System
torque check: txheeb xyuas lub ntsia liaj qhov rooj ua ntej-tightening torque tiv thaiv tus nqi tsim ntawm lub sijhawm uas tau teev tseg los ntawm cov chav kawm.
Kev tshuaj xyuas clip: saib cov ntiv taw dab dej, txav chaw, tawg thiab poob ntawm elastic stroke.
Rwb thaiv tsev xyuas: ntsuas kev tiv thaiv rwb thaiv tsev ntawm cov ntsuas ntsuas thiab cov tshuab ntxhua khaub ncaws, tshwj xeeb tshaj yog tom qab tamping lossis tu ua haujlwm.
Corrosion check: tshuaj xyuas cov ntxhua khaub ncaws thiab bolts rau xeb, tshwj xeeb tshaj yog nyob rau hauv qhov av thiab cov ntug dej hiav txwv.
Re-Txoj kev sib tw nruj: tom qab qhib kab, kos cov bolts txhua hli rau thawj peb lub hlis, tom qab ntawd ncua lub sijhawm.
Cov lus nug nquag
Dab tsi clamping quab yuam txaus?
8-10 kN feem ntau yog tsim nyog rau cov kab zoo tib yam; siab -cov tshuab ceev qhia tsawg kawg yog 10 kN thiab hnyav-haul systems 12-15 kN, ib txwm txheeb xyuas tawm tsam tus qauv tsim rau txoj kev tsheb ciav hlau hauv kev siv.
Vim li cas cov clip xav tau ib qho elastic stroke?
Kev mob stroke cia cov clip ua raws li kev tsheb nqaj hlau txav los ntawm qhov kub thiab txias thiab dhau lub log thaum tuav lub zog. Ib qho clip uas tsis muaj stroke txaus los poob lub zog clamping lossis dhau - kev ntxhov siab thiab pob txha.
Yam twg muab cov rwb thaiv tsev?
Insulating gauge blocks thiab insulating washers ua los ntawm siab -lub zog nylon lossis cov ntaub ntawv sib xyaw. Lawv yuav tsum thaiv tam sim no thaum nqa lub tsheb ciav hlau thauj khoom, thiab lawv cov rwb thaiv tsev yuav tsum tau kuaj xyuas hauv kev pabcuam.
Yuav ua li cas koj nrhiav tau ib tug xoob bolt nyob rau hauv tu txhua hnub?
Nrog lub torque wrench tiv thaiv tus tsim torque, thiab los ntawm kev soj ntsuam qhov muag ntawm tus ntiv taw clip: dab ntxwg nyoog los yog tshem tawm ntawm clip kawg yog ib qho kev txhim khu kev qha thaum ntxov ntawm loosening.
Thaum twg yuav tsum tau xaiv ib qho boltless fastening system?
Nyob rau hnyav- tsheb thauj mus los thiab siab - cov kab tsheb thauj mus los uas tus nqi tu thiab taug qab kev ruaj ntseg tseem ceeb tshaj plaws. Thawj tus nqi siab dua yog offset los ntawm kev saib xyuas lub neej qis dua thiab kev pab lub neej ntev dua.
Yuav ua li cas yog tias rwb thaiv tsev tsis kam poob?
Lub teeb liab tam sim no xau mus rau lub txaj pw thiab hauv av, ua rau lub tsheb ciav hlau nrhiav tsis tau. Ua tsis tiav cov insulating qhov chaw yuav tsum tau hloov thiab qhov kev tiv thaiv rov- txheeb xyuas ua ntej tus khiav rov qab mus rau qhov kev pab cuam.
