↵Rail skl Fastening System
Ib txoj kev tsheb ciav hlau SKL clip yog ibnro-resistant caij nplooj ntoos hlav steel fastening tivthaivuas ua haujlwm dhau lostxhais elastic deflection ntawm lub xub pwg ruaj thiab ib tug threaded T-bolt los ua ke- tshwj xeeb ntawm tag nrho cov tsheb ciav hlau fasteners raws li tustsuas yog clip uas yuav tsum tau muaj ob -theem mounting txheej txheem (nres → ua haujlwm), covtsuas yog clip uas nws clamping quab yuam yog kho los ntawm bolt torque es tsis yog geometry ib leeg, thiab covtsuas yog clip tsev neeg qhov kev hloov pauv ncaj qha qhia qhov nominal ntiv taw load hauv kilonewtons(SKL12=12 kN, SKL15=15 kN, SKL18=18 kN)
Technical Specifications:
| Variant | Nominal Force | Fixation Method | Torque Spec | Hom Lub xub pwg nyom | Common Mis-Kev xaiv qhov tshwm sim |
|---|---|---|---|---|---|
| SKL 12 | 12 kN ± 1 kN | T-bolt + txiv ntseej ntawm ribbed phaj | 150-180 Nm | Recessed hnab tshos, eccentric tus pin | Siv nyob rau hauv SKL15 lub xub pwg nyom → pob taws zaum siab, ntiv taw clearance<2 mm |
| SKL 14 | 12 kN ± 1 kN | Plaub ntsia hlau spikes + baseplate | 150-180 Nm | Turnout bearer, tsis kho | Haum rau slab khiav → tsis muaj kev hloov kho sab nraud |
| SKL 15 | 15 kN ± 1 kN | Ntsia hlau ntsia hlau + yas dowel | 180-200 Nm | B90 / B110 qhob thaiv | Nruab rau hauv SKL12 lub xub pwg nyom → pob taws lub hnab ris tsis sib haum, clip rattles |
| SKL 18 | 18 kN ± 1 kN | Ntsia hlau ntsia hlau + HDG dowel | 200-220 Nm | Reinforced hnyav nqa block | 60Si2CrA hloov → brittle puas ntawm -30 degree |
| SKL-CF | 12-15 kN | Rwb thaiv tsev T-bolt | 150-180 Nm | Dielectric cais phaj | Txheem SKL ntsia → traction lub ntiaj teb txhaum |
Performance Range:
Parked Position Logic- SKL clips yog lub Hoobkas- sib dhos ntawm cov neeg pw hauvtsis yog -tensioned nres txoj hauj lwmnrog lub hauv paus voj tsa 8-12 mm saum rail ko taw. Tom qab kev tsheb ciav hlau tso, clip yogtsav tom qab 15-20 mmmus ua hauj lwm txoj hauj lwm, ces tensioned los ntawmT-bolt torque. Qhov ob -txoj kev no ua rau 1.2 km / hnub mechanized tso.
Torque=Force, Tsis Deflection- Tsis zoo li E- Clip qhov twg ntiv taw qhov sib txawv kwv yees quab yuam, SKL clamping quab yuam yogteem los ntawm bolt torque, tsis clip deflection. SKL15: 15 kN xav tau180-200 Nm (M22 thread). Undertorque (−20 Nm) → creep >3 hli / xyoo. Overtorque (+25 Nm) → yas yielding ntawm T-bolt rooj → tas zog poob.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- SKL12 vs SKL14 Illusion- Ob leeg ntsuas 12 kN. TSW 12:ballastless slab khiav, T-bolt fixation, eccentric pin hloov. TSW 14:turnout ribbed baseplates, plaub- ntsia hlau fixation, tsis kho. Dimensionally zoo sib xws tab sisxub pwg hnab tshos geometry txawv. Hloov → clip binds lossis muaj 3-5 hli lateral play → gauge wander.
- SKL15 Lub xub pwg nyom Specification- Xav tauB90 / B110 qhob pw tsaug zog lub xub pwg blocksnrog optimized luj taws lub rooj zaum. Txhim kho SKL15 rau hauv SKL12 xub pwg →pob taws zaum 2 mm siab dhau lawm→ ntiv taw clearance txo 40% → clip yields ntawm 12 kN es tsis txhob 15 kN. Cov tsos mob ntawm thaj chaw: rail lifts clip nyob rau hauv lub tsheb ciav hlau.
- SKL18 Arctic alloy- 54SiCr6 nrog V/Nb micro- alloy,tsis yog 60Si2CrA. Kev ua yuam kev: hloov 60Si2CrA ntawm −40℃→ brittle transition kub tshaj → clip tawg thaum thawj lub caij ntuj no cuam tshuam. XRF ntes Cr, Si;tsis tuaj yeem ntes V, Nb. Mill daim ntawv pov thawj yuav tsum tau.
