Rail Plate Structure Optimization thiab Track Condition Adaptation Technology
Cov ntsiab lus mob dab tsi yog qhov tseem ceeb los ntawm kev ua kom zoo dua ntawm cov phaj nias sab nraud?
Cov ntawv xovxwm niaj hnub feem ntau yog tiaj tus- cov qauv phaj, nrog cov ntsiab lus mob ntawm cov ntsiab lus ntawm kev ntxhov siab thiab tsis zoo. Lub tiaj tus- phaj nias phaj muaj qhov sib txuas me me nrog lub hauv paus kev tsheb nqaj hlau, thiab cov kev ntxhov siab hauv cheeb tsam tuaj yeem tshwm sim thaum lub tsheb ciav hlau vibration, ua rau deformation thiab tawg ntawm nias phaj ntug. Nws sab tsis muaj cov qauv qhia, uas yooj yim rau kev hloov pauv thaum lub sijhawm teeb tsa thiab tsis tuaj yeem haum cov tsheb ciav hlau kom raug. Kev xoos tuaj yeem tshwm sim vim qhov khoob khoob tom qab ua haujlwm ntev -. Rau lub zog sab nraud ntawm cov kab nkhaus, cov ntawv xovxwm ib txwm muaj tsis txaus los tiv thaiv - lub peev xwm plam, uas yooj yim ua rau kev hloov pauv ntawm txoj kev tsheb ciav hlau. Qhov zoo tshaj plaws nias phaj tuaj yeem daws cov ntsiab lus mob no los ntawm kev ua kom muaj kev sib cuag arc thiab tsim cov thawj coj coj, txhim kho qhov haum nrog cov tsheb ciav hlau thiab tiv thaiv -slip muaj peev xwm. Nyob rau tib lub sijhawm, cov qauv kev ua kom zoo kuj tseem tuaj yeem txo cov khoom siv rov ua dua, ua tiav lub teeb yuag ntawm qhov chaw ntawm kev ua kom muaj zog, thiab txo qis kev teeb tsa thiab kev thauj mus los.
Nyob rau hauv dab tsi yog qhov kev txhawb zog hauv zos tsim ntawm nias daim hlau rau hnyav -cov kab tau cuam tshuam?
Nias daim hlau rau hnyav- cov kab tsheb yuav tsum tau nqa lub zog ntsug ntau dua thiab kev cuam tshuam rau sab nraud, thiab cov qauv tsim kho hauv zos tsom rau cov kev ntxhov siab tseem ceeb- cov kabmob. Qhov chaw nyob ib ncig ntawm lub qhov uas lub phaj nias txuas nrog lub ntsia liaj qhov rooj yog thickened, 2-3 hli tuab dua li cov ntawv xovxwm zoo tib yam, tsim ib lub voj voog lub voj voog kom tsis txhob lub qhov deformation thiab tearing thaum lub ntsia liaj qhov rooj yog nruj. Qhov chaw ua hauj lwm ntawm lub phaj nias nyob rau hauv kev sib cuag nrog cov tsheb ciav hlau yog tsim los ntawm toothed kev ntxhib los mos kom muaj kev sib txhuam coefficient, txhim kho lub peev xwm los tiv thaiv- plam, thiab tiv thaiv kev tsheb ciav hlau thaum hnyav - tsheb ciav hlau hla. Lub ntug ntawm lub phaj nias txais lub voj voog arc hloov pauv hloov ntawm txoj cai ib txwm muaj - lub kaum sab xis qauv, txo qis kev ntxhov siab thiab kev pheej hmoo ntawm kev tawg. Cov khoom siv yog siab -lub zog alloy steel, thiab nws cov hardness thiab toughness yog ho txhim khu kev qha tom qab quenching thiab tempering kev kho mob, uas muaj peev xwm tiv thaiv rov qab los ntawm hnyav loads. Qee qhov hnyav-cov ntawv xovxwm kuj tseem ntxiv cov hlua txuas txuas ntxiv txhawm rau txhim kho lub zuag qhia tag nrho nruj thiab zam kom tsis txhob muaj kev ntxhov siab ntev.
Dab tsi yog qhov kev hloov pauv loj ntawm cov ntawv xovxwm sib raug rau cov kev sib txawv ntawm kev tsheb ciav hlau?
Qhov luaj li cas ntawm cov phaj nias yuav tsum raug sib npaug nrog cov lus qhia kev tsheb nqaj hlau. Cov phaj nias sib raug rau 50kg / m rail muaj qhov dav ntawm 80-90mm thiab tuab ntawm 12-14mm kom paub meej tias kev hloov kho rau txoj kab tsheb ciav hlau dav dav thiab thaj chaw tiv tauj tsis pub tsawg dua 80%. Lub 60kg / m rail muaj ib tug dav rail puag, thiab sib txuas xovxwm phaj dav yuav tsum tau nce mus rau 90-100mm, thiab lub thickness mus rau 14-16mm kom disperse ntau dua load siab. Lub 75kg / m hnyav-haul tsheb ciav hlau yuav tsum tau muab sib xyaw nrog cov phaj tuab tuab nrog qhov dav ntawm 100-110mm thiab tuab ntawm 16-18mm, thiab cov hniav zoo nkauj ntawm cov phaj nias yog qhov sib sib zog nqus los txhim kho kev koom tes nrog cov tsheb ciav hlau. Thaum lub sij hawm hloov kho, nws yog ib qho tsim nyog los xyuas kom meej tias lub qhov arc ntawm lub phaj nias yog zoo ib yam nrog lub tsheb ciav hlau puag arc, nrog ib tug deviation ntawm tsawg tshaj li los yog sib npaug zos rau 0.5 hli, tsis txhob muaj kev ntxhov siab concentration tshwm sim los ntawm point contact. Tsis tas li ntawd, lub qhov ntsia hlau qhov sib nrug ntawm lub phaj nias yuav tsum tau ua kom raug raws li qhov tshwj xeeb qhov chaw ntawm tus neeg pw tsaug zog, nrog rau qhov sib txawv ntawm tsawg dua lossis sib npaug li 2 hli, kom ntseeg tau tias kev txhim kho du thiab tsis sib xws.
Dab tsi yog qhov sib txawv ntawm cov ntawv xovxwm rau cov kab nkhaus thiab cov kab ncaj?
Thaum cov tsheb ciav hlau hla dhau cov kab nkhaus, sab centrifugal quab yuam yog tsim tawm, yog li qhov kev tiv thaiv - sab nraub qaum kev ua tau zoo tsim ntawm nias daim hlau rau cov kab nkhaus yog qhov tseem ceeb dua. The toothed texture density of the working surface of curved pressing plates is higher, and the friction coefficient is increased by more than 30% compared with that of straight line pressing plates, which can effectively resist lateral forces. Qee qhov nkhaus nias daim hlau ntxiv rau cov thawj coj txwv sab nraud uas haum nrog rau sab kev tsheb ciav hlau kom txwv txoj kev tsheb ciav hlau sab nraud. Tus thawj qhov siab feem ntau yog 5-8mm, kho raws li qhov nkhaus nkhaus. Nias daim hlau rau cov kab ncaj nraim tsom ntau rau ntsug load-bearing stability, nrog ib tug kuj yooj yim qauv thiab ntiav ua hauj lwm nto kev ntxhib los mos kom sib npaug haum thiab installation yooj yim. Cov ntaub ntawv toughness ntawm nkhaus nias daim hlau yuav tsum siab dua, nrog rau kev cuam tshuam lub zog (-20 degree) ntawm ntau dua los yog sib npaug rau 40J kom tsis txhob nkig tawg los ntawm lateral rog; qhov cuam tshuam lub zog ntawm txoj kab ncaj nraim nias daim hlau Ntau dua lossis sib npaug ntawm 30J tuaj yeem ua tau raws li qhov yuav tsum tau ua. Lub bolt qhov txoj hauj lwm tsim ntawm ob yog txawv. Qhov txoj hauj lwm ntawm qhov nkhaus nias phaj yog ze rau ntawm txoj kab nruab nrab ntawm txoj kab tsheb ciav hlau txhawm rau txhim kho qhov kev txwv sab nraud.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev tshuaj xyuas zoo tom qab nias lub phaj installation?
Tom qab kev teeb tsa, nws yog ib qho tsim nyog los xyuas qhov haum ntawm lub phaj nias thiab lub tsheb ciav hlau. Siv lub ntsuas ntsuas 0.3 hli los ntsuas qhov sib chwv sib kis, uas yuav tsum tsis txhob muab tso rau kom nruj kom haum yam tsis muaj loosening. Use a torque wrench to detect the bolt tightening torque:>=300N·m for ordinary lines and>=450N·m for heavy-haul lines, with uniform torque to avoid uneven local force. Txheeb xyuas cov qib ntawm cov phaj nias nrog ib theem, nrog qhov sib txawv ntawm Tsawg dua lossis sib npaug li 0.5mm / m los tiv thaiv kev tsheb ciav hlau quab yuam sib txawv los ntawm inclination. Saib xyuas qhov zoo li ntawm cov phaj nias, tsis muaj deformation, tawg, xeb thiab lwm yam tsis xws luag, thiab cov hniav zoo nkauj tsis puas los xyuas kom meej tias cov khoom tiv thaiv ({9}}slip) ua tau raws li tus qauv. Ua raws li niaj zaus- kev tshuaj xyuas, rov xyuas seb lub phaj nias puas tau hloov chaw thiab seb cov bolts puas xoob tom qab lub tsheb ciav hlau hla. Tshawb xyuas cov kab nkhaus ib zaug ib lub hlis twg thiab cov kab ncaj nraim ib zaug txhua rau lub hlis, thiab ua raws sij hawm tswj cov xwm txheej tsis tsim nyog.
