Lub tsheb ciav hlau yog dab tsi thiab nws ua haujlwm li cas?
A tsheb ciav hlauyog ib qho dov steel uas ua rau qhov chaw khiav thiab kev taw qhia rau lub tsheb ciav hlau lossis crane log, thiab nws yog qhov tseem ceeb tshaj plaws thauj khoom -cov kabmob hauv txhua qhov kev tsheb ciav hlau. Cov ntsia hlau ntsia tau rau hauv cov khub ua ke thiab tsau rau cov neeg pw tsaug zog lossis cov kab hluav taws xob uas siv cov txheej txheem fastening, tsim kom muaj txoj hauv kev txuas ntxiv uas tso cai rau cov tsheb txav mus los tau nyab xeeb, ua haujlwm zoo, thiab ua haujlwm tau zoo.
- Los ntawm cov qauv tsim, thawj txoj haujlwm ntawm kev tsheb ciav hlau yog nqa thiab faib cov log tsheb.Thaum lub log hu rau lub taub hau tsheb ciav hlau, kev sib tiv tauj siab heev tau tsim nyob rau hauv ib qho chaw me me. Txoj kev tsheb ciav hlau tus ntoo khaub lig- ntu thiab qib steel yog tsim los tiv thaiv kev khoov, shear, thiab dov kev sib cuag qaug zog, thiab kom kis tau cov rog no los ntawm lub vev xaib thiab lub hauv paus ntawm txoj kev tsheb ciav hlau mus rau hauv cov neeg pw tsaug zog thiab tom qab ntawd mus rau hauv lub pob zeb lossis pob zeb. Qhov kev thauj khoom no -hloov muaj nuj nqi yog qhov tseem ceeb los tiv thaiv kev khiav ntau dhau thiab kev ua haujlwm tsis ua haujlwm.
- Lub luag haujlwm tseem ceeb thib ob ntawm txoj kev tsheb ciav hlau yog coj lub log thiab tuav lub ntsuas qhov tseeb.Lub tsheb ciav hlau lub taub hau profile ua haujlwm ua ke nrog lub log tread thiab flange kom cov tsheb nyob nruab nrab ntawm txoj kev, txawm tias nyob rau hauv kev kub ceev los yog nyob rau hauv lub lateral rog nyob rau hauv nkhaus thiab thaum lub sij hawm braking. Qhov tseeb kev tsheb ciav hlau thiab qhov profile yog qhov tseem ceeb rau kev ua haujlwm kev nyab xeeb thiab kev tiv thaiv derailment.
- Qhov thib peb muaj nuj nqi yog muab ib tug du, nruam dov nto uas txo kev vibration, suab nrov, thiab lub zog poob.Zoo-txoj kev tuav tswj kom txo tau qhov kev sib tw dov, txhim kho cov neeg caij tsheb kom xis nyob, thiab hnav qis dua ntawm ob lub log thiab cov khoom siv taug qab. Vim li no, rails tsis tu ncua hauv av los yog milled los kho qhov zoo ntawm lub taub hau profile thiab tshem tawm qhov tsis xws luag.
Dab tsi yog qhov loj tshaj plaws rail loj?
Qhov loj tshaj rail loj yog hais txogStandard Gauge, ib txoj kab dav ntawm 1,435 mm (4 ft 8½ nyob rau hauv), siv li ntawm 55% ntawm lub ntiaj teb txoj kev tsheb ciav hlau rau cov neeg caij tsheb thiab thauj khoom thauj thoob plaws North America, Europe, Tuam Tshoj, thiab lwm yam. Rau qhov tseeb steel rail qhov ntev,60 kg / m(lossis zoo sib xws cov tsheb ciav hlau hnyav xws li 50 kg / m, 54E1, 115RE) muaj ntau heev rau txoj kev tsheb ciav hlau loj, xaiv rau lub zog thiab tus nqi-kev ua tau zoo, featuring ib qho I- nqaj zoo rau kev thauj khoom.
Raws li tus kws tshaj lij rail fastener tsum,GNEE RAILtuaj yeem muab cov qauv hlau sib txawv xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv hauv kev tsheb ciav hlau, cranes thiab thee mining.
