Dab tsi yog qhov sib koom ntawm ob txoj kev tsheb ciav hlau?
Arail sib koom ua ke is qhov kev sib txuas ntawm ob txoj kev tsheb ciav hlau, tsim los tuav txoj kev tsheb ciav hlau xaus rau hauv qhov chaw horizontally thiab vertically. Nws suav hais tias yog qhov tsis muaj zog tshaj plaws ntawm txoj kev khiav, feem ntau yog tsim los ntawm cov hlau phaj hu ua fishplates (los yog splice tuav) bolted ua ke los ntawm txoj kev tsheb ciav hlau.
GNEE RAILmanufactures ntses daim hlau rau GB lub teeb thiab hnyav rails, UIC txheem rails, DIN536 thiab QU crane rails, JIS rails, AS1085 profiles, BS11 rails, thiab AREMA / ASCE seem, txhawb los ntawm rail-kev sib koom ua pov thawj.
Cov Cheebtsam thiab Hom Rail Joints:
- Fishplates (Joint Bars):Hlau daim hlau uas bolted rau ob sab ntawm cov ntsia hlau txuas rau lawv.
- Ntses Bolts:Siab - carbon steel bolts thiab txiv ntseej siv nrog cov ntses los tiv thaiv kev sib koom tes.
Hom Hom:
- Bolted Joints:Pa txoj kev siv fishplates.
- Welded Joints:Nruam welded rails (CWR) siv los tsim kom muaj kev sib txuas zoo dua, muaj zog dua, thiab ruaj khov dua.
- Insulated Joints:Cov pob qij txha tshwj xeeb siv rau hauv cov chaw taw qhia kom tawg hluav taws xob circuits.
- Compromise Joints:Siv los txuas cov hlua ntawm qhov sib txawv.

Dab tsi yog cov lus qhia tshwj xeeb rau kev sib koom ua ke rail?
Common rail joint bars (fishplates) yog tsim los kom phim cov kev tsheb ciav hlau tshwj xeeb (xws li, AREMA, UIC, BS) thiab feem ntau muaj 4 lossis 6 lub qhov ntsia hlau, nrog 24-inch lossis 36-inch lengths, feem. Cov ntsiab lus tseem ceeb suav nrog cov hlau muaj zog (45 #, 50Mn, 42CrMo), kev kho cua sov kom ua haujlwm ntev, qhov sib txawv ntawm lub qhov ntsia hlau (piv txwv li, 6 "x6"x7-1 / 8"x6"x6"), thiab tshwj xeeb profiles rau lub taub hau yooj yim.
Common Specifications rau Rail Joint Bars:
- Txheem & Profiles:Tsim kom tau raws li AREMA (piv txwv li, 115RE, 132-136RE), UIC (piv txwv li, UIC54, UIC60), lossis British Standard (BS) specifications.
