Dab tsi tseem ceeb Fasteners suav nrog Standard UIC54 rail ntses phaj?

Txhawm rau kom muaj kev ncaj ncees ntawm txoj kev tsheb ciav hlau, cov kab sib koom ua ke (feem ntau hu ua ntses daim hlau) yuav tsum tau muab khi rau hauv lub vev xaib tsheb ciav hlau nrog siab - zog, kev co- cov khoom siv tiv taus. Rau tus qauv UIC54 (tam sim no raug xaiv raws li 54E1 raws li European tus qauv EN 13674-1) rail profile, xaiv cov fasteners kom raug yog ib qho tseem ceeb rau kev nyab xeeb thiab kav ntev.

 

Ib tug qauvUIC54 rail sib koom ua kekev sib dhos yuav tsum muaj cov txheej txheem siab - lub zog fasteners kom ruaj ntseg clamp cov ntses daim hlau mus rau lub vev xaib rail. Txhua txheej txheem sib koom ua ke muaj peb qhov tseem ceeb fasteners:

 

2 x Joint Bars (ib qho rau txhua sab ntawm txoj kev tsheb nqaj hlau).

4 x Fishbolts (feem ntau M24 x 145mm lossis M24 x 150mm).

4 x Caij nplooj ntoos hlav Washers (kom muaj zog tiv thaiv kev vibrations).

4 x nut.

Cov ntses ntsia liaj qhov rooj siv nyob rau hauv UIC54 Fishplate tsis yog tus qauv kev lag luam ntsia liaj qhov rooj. Nws tau tsim tshwj xeeb rau kev siv tsheb ciav hlau:

 

• Khawm Lub taub hau Oval Neck Design:Lub ntsia liaj qhov rooj nta ib puag ncig, dome-zoo li khawm taub hau rau sab nraud, nrog lub oval-zoo li lub caj dab ncaj nraim hauv qab nws. Lub caj dab oval txuas rau hauv qhov sib txuam oval -zoo li lub qhov ntawm UIC54 ntses phaj. Lub tshuab ntsuas phoo no tiv thaiv lub ntsia liaj qhov rooj los ntawm kev tig thaum lub txiv ntoo raug kaw los yog xoob los ntawm sab nraud, tso cai rau ib leeg - tu cov cuab yeej.

 

• Siab -Tensile Steel:Raws li tus qauv UIC 864-2, cov bolts no feem ntau yog tsim nyob rau hauv Qib 8.8 lossis Qib 10.9. Qhov no ua kom cov bolts tuaj yeem tiv taus qhov hnyav shear thiab tensile quab yuam los ntawm lub caij thermal expansion ntawm cov ntsia hlau.

Cov txiv ntoo ua haujlwm nyob rau hauv tandem nrog lub siab - lub zog ntsia liaj qhov rooj los muab qhov tsim nyog clamping quab yuam:

 

• Qib Matching:Ib qho kev saib xyuas engineering feem ntau yog siv tus qauv - qib txiv ntoo nrog lub siab - tensile bolt. Rau UIC54 pob qij txha, Qib 8.8 ntsia liaj qhov rooj yuav tsum tau ua ke nrog Qib 8 txiv ntoo, thiab Qib 10.9 ntsia liaj qhov rooj nrog Qib 10 txiv ntoo kom tsis txhob muaj xov stripping hauv qab load.

 

• Heavy Hex Profile:Cov txiv ntseej no muaj qhov dav dav dua thoob plaws lub tiaj tus piv rau cov qauv hex txiv ntseej, faib cov clamping siab hla thaj tsam dav dua thiab muab kev tuav zoo dua rau kev sib tw wrenches.

 

 

Cov tsheb ciav hlau hla dhau los ua rau muaj kev mob siab, siab - zaus vibrations uas tuaj yeem yooj yim rov qab cov txiv ntoo txheem. Lub caij nplooj ntoos hlav ntxhua khaub ncaws yog thawj tiv thaiv kev co -induced loosening:

 

• Tsis tu ncua Tension:Muab ob npaug rau-coil washers ua zoo li hnyav- lub luag haujlwm springs. Thaum cov txiv ntoo yog torqued, cov coils compressing, khaws cia txhua yam zog. Yog hais tias lub tsheb ciav hlau sib koom ua haujlwm hloov lossis muaj kev vibration, lub tshuab ntxhua khaub ncaws nthuav dav me ntsis kom tswj tau lub zog txuas txuas ntxiv.

 

• Kev them nyiaj rau Thermal Movement:Steel rails undergo tseem ceeb thermal expansion thiab contraction. Lub caij nplooj ntoos hlav ntxhua khaub ncaws tso cai rau kev sib koom ua ke "ua pa" me ntsis thaum tswj qhov tsawg kawg nkaus ntawm cov qauv tsim kom muaj kev ruaj ntseg ntawm kev sib koom tes.

Installation Cov kauj ruam rau Rail Fish Bolts

 

1. Kev npajXyuas kom cov chaw sib cuag ntawm lub phaj phaj thiab cov tsheb ciav hlau, nrog rau cov bolts, yog lubricated kom txo tau kev sib txhuam thiab corrosion.

 

2. Ntxig BoltsNtxig cov ntses bolts rau hauv lub qhov ntawm lub phaj thiab lub tsheb ciav hlau. Nco ntsoov tias cov txiv ntoo yuav tsum tau staggered (alternating sab) kom tsis txhob cuam tshuam.

 

3. Tightening BoltsRau 4-lub qhov ntses phaj, thawj zaug zawm ob lub bolts nruab nrab, ces zawm cov bolts ntawm ob qho kawg. Tom qab qhov kawg bolts tau nruj, rov ua dua ob lub bolts nruab nrab kom ntseeg tau tias tag nrho cov bolts raug quab yuam sib xws.

 

4. Fastening BoltsSiv 55 cm wrench ua los ntawm ib tus neeg. Tsis txhob siv lub qhov ntev ntev ntev los yog muaj ob tus neeg nruj ib txhij los tiv thaiv kev ntxhov siab tsis sib xws lossis kev puas tsuaj rau cov bolts.

 

FAQ

 

Q1: Puas yog tus qauv kev lag luam M24 bolts siv los ruaj ntseg UIC54 rail ntses phaj?

Tsis yog. Standard industrial bolts yuav tsum tsis txhob muab hloov rau txoj kev tsheb ciav hlau -cov bolts tshwj xeeb. Rail ntses bolts muaj lub cim pob taub hau thiab lub caj dab oval tsim los ntawm cov qauv xws li UIC 864-2. Yog tsis muaj lub caj dab oval xauv rau hauv qhov sib thooj oval qhov ntawm UIC54 ntses phaj, lub ntsia liaj qhov rooj yuav tig ywj siab thaum cov kws tshaj lij sim ua kom nruj lossis xoob cov txiv ntoo los ntawm lwm sab. Tsis tas li ntawd, cov txheej txheem kev lag luam bolts tsis tsim los tiv thaiv qhov kev sib tsoo huab cua thiab dynamic qaug zog loads tshwj xeeb rau cov pob qij txha railway.

 

Q2: Dab tsi yog qhov txawv ntawm ib qho -coil thiab ob npaug - coil caij nplooj ntoos hlav ntxhua hauv UIC54 cov rooj sib txoos?

Thaum ob qho tib si pab tiv thaiv kom tsis txhob xoob hauv kev vibration, ob npaug -coil caij nplooj ntoos hlav ntxhua khaub ncaws (xws li Fe6 style) muab qhov muaj zog ntau dua deflection thiab elastic zog cia dua ib zaug -coil washers. Nyob rau hauv siab -frequency dynamic loads los ntawm hnyav- tsheb thauj neeg los yog neeg nrog caij tsheb ciav hlau, ob-coil washers yog zoo dua los ntawm kev them nyiaj rau kev hnav thiab me steel so, uas ua rau txo qis kev txij nkawm.

 

Q3: Ntev npaum li cas yuav tsum tau kuaj xyuas lossis hloov UIC54?

Cov fasteners yuav tsum tau soj ntsuam qhov muag pom thaum lub sij hawm kev tu ncua taug kev. Kev hloov pauv nyob ntawm qhov hnyav ntawm cov tsheb khiav ceev, qag loads, thiab ib puag ncig yam tseem ceeb (xws li av av thiab ntsev raug). Feem ntau, lub caij nplooj ntoos hlav ntxhua khaub ncaws yuav tsum tau hloov yog tias lawv pom cov kab nrib pleb lossis tsis rov qab mus rau lawv cov duab coiled thaum decompression (poob elasticity). Siab- lub zog bolts thiab txiv ntseej yog feem ntau hloov thaum lub caij tsheb ciav hlau de- kev ua haujlwm hnyav lossis thaum hloov cov phaj ntses hnav.
