Tom ntej: Ib Qhov Nto Ua Haujlwm Hloov Ob Lub Rail
Ib txoj kev tsheb ciav hlau ib txwm nqa lub log ntawm ob txoj kab sib txuas sib txuas ntawm qhov ntsuas 1435 hli, txhawb nqa ntawm cov neeg pw tsaug zog thiab ballast lossis pob zeb pob zeb. Lub fastening system tuav lub tsheb ciav hlau ko taw, hloov ntsug thiab sab loads mus rau lub sleeper, thiab resists longitudinal creep. Lub straddle monorail tshem tawm qhov thib ob txoj kev tsheb ciav hlau tag nrho: roj hmab- cov tsheb yuag straddle ib txoj kab kev taw qhia, feem ntau yog lub pob zeb prestressed beam 700 mus rau 850 mm dav, thiab cov log khiav yob ntawm steel khiav daim hlau tsau rau saum npoo ntawm cov nqaj. Kev taw qhia yog muab los ntawm kab rov tav kev taw qhia lub log khiav tawm tsam steel kev taw qhia log ntsia ntawm ob sab ntawm lub nqaj. Vim tias tsis muaj qhov ntsuas qhov ntsuas kom tswj tau, tag nrho lub tswv yim ntawm txoj kab nrawm hloov ntawm kev tsheb ciav hlau - mus rau - pw tsaug zog clamping rau kab teeb - mounted anchorage.
Load Path thiab lub luag hauj lwm ntawm Fastening System
Hauv ob - kev tsheb ciav hlau taug qab txoj kev thauj khoom yog lub log, tsheb ciav hlau, tsheb ciav hlau ncoo, pw tsaug zog thiab ballast, thiab cov clip yuav tsum clamp lub tsheb ciav hlau ko taw nrog lub taw taw hnyav thaum tso cai rau ncua ntev. Nyob rau hauv ib tug monorail txoj kev thauj khoom yog khiav log tsheb, steel khiav phaj, thauj tog rau nkoj bolt thiab pob zeb beam. Lub thauj tog rau nkoj ntsia liaj qhov rooj yog embedded nyob rau hauv lub pob zeb los yog tsau nyob rau hauv ib tug pre- nrum cam khwb cia, thiab lub phaj khiav yog drilled txais lub ntsia liaj qhov rooj. Kev taw qhia lub log quab yuam, uas yog qhov tseem ceeb hauv kev nkhaus, yog nqa kab rov tav los ntawm kev taw qhia lub log tsheb mus rau hauv clips thiab bolts ntawm lub nqaj sab ntsej muag. Lub kaw lus fastening yog li ua tau peb txoj haujlwm: nws yuav tsum tuav lub phaj khiav ncaj nraim hauv qab lub log rov qab, clamp lub log tsheb ciav hlau kom ruaj ntseg tiv thaiv kev thawb sab nraud, thiab khaws tag nrho cov nyob hauv- cov khoom siv hlau thaiv los ntawm qhov rov qab los tam sim no.
Cheebtsam -Level Differences
Khiav daim phiaj thiab thauj tog rau nkoj bolts
Monorail khiav daim hlau yog dov steel phaj, feem ntau 10 mus rau 16 hli tuab, machined tiaj thiab bolted rau lub beam saum. Thauj tog rau nkoj bolts feem ntau yog siab - lub zog bolts nrog cov resin los yog cov khoom siv thauj tog rau nkoj embedded rau hauv lub pob zeb, nruj rau ib qho kev qhia torque nrog cov xauv lub tshuab ntxhua khaub ncaws lossis cov nplaum nplaum kom tsis txhob xoob hauv qab vibration. Ob -rail fastenings, los ntawm qhov sib piv, clamp lub tsheb ciav hlau ko taw nrog lub caij nplooj ntoos hlav clips thiab hloov thauj khoom los ntawm lub hauv paus los yog kev kho ncaj qha.
Guide Wheel Rails
Cov kev taw qhia log tsheb ciav hlau yog ib qho tshwj xeeb steel seem los yog ib lub tshuab ua haujlwm ruaj khov rau ntawm kab teeb los ntawm clips thiab bolts. Nws txoj hauj lwm ntsug thiab qhov ncaj yog teem nrog shims, vim hais tias cov kev taw qhia log clearance, feem ntau yog ob peb millimeters, tswj kev caij zoo thiab lateral stability. Qhov kev hloov kho no zoo li lub ntsuas ntsuas ntawm cov pa fastenings tab sis ua rau ntawm lub ntsej muag ntsug.
Hluav taws xob rwb thaiv tsev
Monorail traction systems siv DC cov khoom siv nrog cov ntawv khiav ua ib feem ntawm lub voj voog. Rwb thaiv tsev pads, iav-fiber- siv cov epoxy bushings thiab insulating lub tes tsho yog siv nyob rau hauv txhua txhua bolted interface los tiv thaiv stray tam sim no mus rau lub pob zeb beam thiab tiv thaiv kev taw qhia thiab grounding. Rwb thaiv tsev tiv thaiv tau teev tseg thiab kuaj raws li ib feem ntawm kev saib xyuas niaj hnub, zoo ib yam li cov hlua hluav taws xob sib txuas hauv ob- kev tsheb ciav hlau.
Daim ntawv thov Scenario
Straddle monorail systems yog tsim los rau hauv nroog txoj kev thauj mus los hauv nroog nrog txoj kev nkhaus nruj thiab cov qib siab, vim tias cov log tsheb roj hmab thiab cov nqaj ib leeg tso cai rau gradients ntawm 6 feem pua thiab nkhaus radii ntawm 50 m lossis tsawg dua, deb dua li cov kev txwv ntawm steel - log ob - tsheb ciav hlau. Ncua monorails, qhov twg lub tsheb dai hauv qab ntawm lub nqaj, siv qhov zoo sib xws tab sis hloov pauv ntawm cov phiaj khiav thiab cov lus qhia. Ob -rail fastening systems tseem yog tus qauv rau mainline, metro, hnyav-haul thiab tramway khiav, qhov twg siab qag loads, ntev kev pab cuam lub neej thiab standard gauge interchangeability yog txiav txim.
Kev xaiv thiab kev saib xyuas
Txheeb xyuas cov qauv thauj tog rau nkoj bolt thiab torque specification tiv thaiv kev khiav phaj tsim ua ntej yuav khoom; phaj thickness thiab bolt qhov sib txawv tsis sib hloov ntawm cov tuam ntxhab.
Siv shims nyob rau hauv phau ntawv qhia lub log tsheb los teeb tsa txoj kab ntsug; sau cov shim pawg nyob rau hauv daim ntawv tu.
Tshawb xyuas kev tiv thaiv kev tiv thaiv ntawm txhua qhov bolted interface thaum lub sijhawm ua haujlwm thiab ntawm lub sijhawm teem tseg.
Retorque thauj tog rau nkoj bolts tom qab thawj lub hlis ntawm kev pabcuam, tom qab ntawd ntawm lub voj voog teem sijhawm, vim tias pob zeb nkag thiab qhov rooj sib hais txo qhov pib ua ntej.
Tshawb xyuas cov phaj khiav ntawm qhov chaw rau pitting, corrugation thiab ntug deformation; kev sib tsoo tsuas yog ua tau nyob rau hauv qhov tob txwv ua ntej hloov.
Kev Ntseeg Tsis Zoo
Monorail fastenings yog tib yam li crane rail lossis tram rail fastenings. Nyob rau hauv qhov tseeb qhov mounting nto, load txoj kev thiab rwb thaiv tsev yuav tsum tau sib txawv, thiab qhov chaw yog interchangeable.
Lub monorail tsis xav tau kev ntsuas ntsuas. Cov nqaj thiab cov log coj hloov pauv qhov ntsuas qhov ua haujlwm, tab sis kev hloov kho ntsug thiab sab nraud tseem xav tau thiab ua tiav nrog shims thiab spacers.
Txhua qhov siab - lub zog ntsia hlau tuaj yeem thauj cov phaj khiav. Nyob rau hauv kev xyaum lub embedded thauj tog rau nkoj, bolt qib, corrosion tiv thaiv thiab rwb thaiv tsev yuav tsum tau sib phim rau lub beam tsim thiab traction system.
Cov lus nug nquag
Q1: Puas yog monorails siv cov qauv tsheb ciav hlau?
Tsis yog. Straddle monorail khiav qhov chaw yog steel daim hlau ntawm lub pob zeb ua ke, tsis yog rail seem ntawm cov neeg pw tsaug zog, yog li cov qauv tsheb ciav hlau tsis siv. Kev taw qhia lub log tsheb yuav siv cov clip- hom fastenings, tab sis lawv tau mounted rau ntawm lub beam sab thiab tsis interchangeable nrog ob -rail khiav clips.
Q2: Yuav ua li cas nqa lub tsheb hnyav nyob rau hauv straddle monorail?
Cov log khiav yob ntawm steel khiav daim hlau bolted mus rau sab saum toj ntawm txoj kab nqaj. Cov paib kis tau cov log tsheb sib txuas rau hauv cov pob zeb los ntawm thauj tog rau nkoj bolts thiab embedded daim hlau.
Q3: Yuav ua li cas yog hluav taws xob rwb thaiv tsev nyob rau hauv monorail khiav?
Insulating pads, epoxy bushings thiab lub tes tsho cais bolted steel Cheebtsam los ntawm cov nqaj thiab rov qab Circuit Court, thiab rwb thaiv tsev tiv thaiv raug txheeb xyuas los ntawm kev sim thaum lub sij hawm commissioning thiab txij nkawm.
Q4: Vim li cas lub monorail xav tau kev taw qhia log tsheb?
Kev taw qhia lub log khiav tawm ntawm txoj hlua ntawm ob sab ntawm lub nqaj kom muab kev taw qhia sab nraud hauv qhov nkhaus thiab tiv thaiv sab quab yuam, hloov lub flange -rail kev sib tshuam ntawm cov pa khiav.
Q5: Puas tuaj yeem siv ob- txoj hlua khi hlua khi rov qab siv dua ntawm ib lub monorail?
Tsis yog. Bolt qauv, phaj geometry, rwb thaiv tsev tsim thiab cov ntaub ntawv thauj khoom sib txawv, yog li cov khoom yuav tsum tau muab tshwj xeeb rau kev tsim qauv monorail.
Q6: Muaj pes tsawg lub monorail fastenings soj ntsuam?
Thauj tog rau nkoj bolt torque, kev qhia kev tsheb ciav hlau thiab kev tiv thaiv hluav taws xob feem ntau raug kuaj xyuas ntawm lub sijhawm teev tseg los ntawm tus neeg teb xov tooj, feem ntau txhua txhua 3 mus rau 6 lub hlis, nrog rau kev soj ntsuam cov phaj saum npoo ntawm lub voj voog zoo sib xws.
