SKL 300 fastening system Txheej txheem cej luam
SKL 300 fastening system rau tsis-ballasted khiav muaj ntau yam zoo ntawm cov qauv yooj yim, nruj kev twb kev txuas, zoo elasticity, loj clamping quab yuam, zoo tiv thaiv creeping tsis kam, yooj yim installation, yooj yim txij nkawm, txhim khu kev qha zoo, ntev kev pab cuam lub neej, thiab lwm yam.
SKL 300 fastening system yog ob txheej txheej elastic nrog lub ncoo hauv qab tsheb ciav hlau thiab lub ncoo hauv qab khi phaj. Nws cov pob zeb sib txuas yuav tsum yog nrog cov kev txhawb nqa rail ditches. Gauge blocks uas feem ntau yog insulated yog siv los kho thiab kho qhov ntsuas qhov deb. Rail bolts thiab pre-embedded dowels ua rail clip kho ntawm insulated washers thiab gauge blocks.
SKL 300 fastening system ua tiav ± 8 hli kab rov tav hloov kho los ntawm kev hloov pauv qhov sib txawv qhov ntsuas qhov sib txawv uas nce lossis txo 1 hli txhua kauj ruam hauv thaj tsam ntawm ± 16 hli.
SKL 300 fastening system muaj peb txoj hauv kev hloov qhov siab, raws li cov yas kho cov ntaub ntawv, cov ntaub ntawv rail thiab steel kho phaj. Kev kho qhov siab yog li ntawm -4mm txog 56mm. Yuav tsum tau tshwj xeeb, kev hloov kho ntawm cov ntaub ntawv tsheb ciav hlau yog los ntawm -4mm mus rau 2mm, nce lossis txo 1mm txhua kauj ruam, Yas kho ncoo ua ke nrog rail ncoo los ntawm 3mm mus rau 28mm; Yas kho ncoo ua ke nrog rail ncoo thiab steel kho phaj los ntawm 29mm mus rau 56mm.
Static rigidity ntawm SKL 300 fastening system yog 20-30kn/mm, longitudinal anti-creeping resistance Ntau tshaj los yog sib npaug rau 9kn, clamping quab yuam Ntau tshaj los yog sib npaug rau 18kn, clip range＞15mm.
Nyob rau hauv Tuam Tshoj SKL 300 fastening system yog nteg nyob rau hauv txoj kab ntawm Beijing-Tianjin intercity high-speed railway, Wuhan-Guangzhou high-speed railway, Beijing-Shanghai high-speed railway, thiab lwm yam.
