Lub luag haujlwm Cycle ntawm Mining Railway Fastening
Mining railways txawv ntawm mainline neeg nrog caij railways nyob rau hauv peb txoj kev uas dominate fastening tsim: qag loads, ib puag ncig thiab saib xyuas. Ore thiab thee tsheb ciav hlau ib txwm khiav ntawm 30 tonnes thiab siab dua rau ib lub qag, uas txhais tau hais tias txhua qhov clip, ntsia liaj qhov rooj thiab lub hauv paus yog loaded ze rau nws qhov kev qaug zog. Cov khiav yog ib puag ncig los ntawm cov hmoov av abrasive - thee nplua, hlau ore concentrate los yog overburden - uas ua haujlwm nws txoj hauv kev rau hauv xov, clips thiab insulators zoo li lapping compound. Thiab vim hais tias cov kab khiav los ntawm cov qhov pits thiab cov chaw khaws cia, cov qhov rais txij nkawm luv luv thiab kev nkag mus tsis zoo. Lub kaw lus fastening rau mining lub luag hauj lwm yog li ntawd xaiv thiab configured txawv los ntawm ib tug txheej txheem mainline system, thiab cov neeg ua hauj lwm uas kho nws tib txoj kev them nyiaj rau nws nyob rau hauv cov khoom tsis ua hauj lwm thiab derailment txaus ntshai.
Hnyav-Load Design: Oversized Bolts thiab Reinforced Clips
Cov txheej txheem tseem ceeb ntawm kev sib tsoo tsuas yog ntsia liaj qhov rooj - thiab - clip set. Bolt diameters pib ntawm M24 thiab nce mus, vim hais tias lub clamping quab yuam yuav tsum tuav txoj kev tsheb ciav hlau tawm tsam ob lub log ntsug thiab lub lateral quab yuam tsim los ntawm hnyav curving. Caij nplooj ntoos hlav clips yog tsim los ntawm tshav kub-kho lub caij nplooj ntoos hlav steel ces lawv tuav lawv clamping quab yuam tom qab rov deflection mus; ib qho clip uas yuav siv sij hawm mus tas li poob cov ntiv taw load uas ua rau txoj kev tsheb ciav hlau nias. Baseplates yog thickened thiab qee zaum ribbed kom kis tau cov concentrated load rau hauv pw tsaug zog, thiab rail ncoo nyob rau hauv ko taw yog siab -load qib xws li TPEE los yog HDPE es tsis yog ib tug mos roj hmab ncoo. Qhov tshwm sim yog lub kaw lus uas lees txais qhov cuam tshuam ntawm overloaded los yog lub log-flatted wagons yam tsis muaj kev cuam tshuam tam sim ntawd.
Plua plav Resistance: Sealing lub Clamping Mechanism
Abrasive plua plav rhuav tshem cov fastenings nyob rau hauv ob txoj kev: nws jams threads thiab clip lub rooj kom clamping quab yuam te, thiab nws grinds deb lub corrosion{0}} tiv thaiv txheej, exposing hlau mus xeb. Mining fastenings yog li tsim los nrog cov pob qij txha kaw - lub rooj zaum clips thiab lub hnab bolts tau kaw los yog tiv thaiv kom cov plua plav tsis tuaj yeem ntim rau hauv qhov chaw ua haujlwm - thiab nrog cov txheej txheem uas tiv taus kev puas tsuaj, feem ntau yog kub-dip galvanizing lossis zinc thicker -raws li qhov system ntawm clip thiab bolt. Kev tu tsis tu ncua nrog cov cua compressed yog ib feem ntawm kev saib xyuas kev tswj hwm: cov plua plav uas tau tso cai los tsim nyob ib puag ncig ntawm qhov clip ko taw loosens lub clamp thiab nrawm hnav. Qhov twg muaj tshuaj lom neeg tshwm sim - de- icing ntsev nyob rau lub caij ntuj no los yog corrosive ore plua plav - stainless hlau los yog zinc-nickel coated Cheebtsam, cov kav dej uas ntws ntsev tawm, thiab kev tshuaj xyuas txhua xyoo yog teev.
Rail Cant thiab Curving Behavior
Ntawm txoj kab nkhaus, lub kaw lus fastening tuav txoj kev tsheb ciav hlau tsis tuaj yeem - tilt ntawm txoj kev tsheb ciav hlau, feem ntau ntawm 1: 40 thiab 1: 20 - los ntawm cov npoo - cov ntaub qhwv los yog kho cov hauv paus. Kho qhov tsis tuaj yeem ua kom lub log- rail tiv thaiv thaj chaw nruab nrab ntawm lub taub hau tsheb ciav hlau, uas ncaj qha txo qis flange hnav thiab clip qaug zog. Cant tau teeb tsa ntawm kev teeb tsa thiab rov- txheeb xyuas thaum lub sijhawm tu, thiab txoj hlua khi tso cai rau kev hloov kho kom zoo los them nyiaj rau kev sib haum xeeb thiab ballast creep. Ib qho xoob los yog tsis raug teeb tsa kom hloov pauv qhov ua tau zoo, ua rau muaj kev pheej hmoo ntawm kev sib cuag flange thiab, qhov phem tshaj plaws, ua rau muaj kev cuam tshuam rau kev sib tsoo ntawm qhov nkhaus ntawm cov mining, uas yog vim li cas torque thiab cant checks yog qhov yuav tsum tau ua ntawm cov ntu curving.
Composite vs Steel Cheebtsam
Composite fastening Cheebtsam - fiber-cov khoom siv yas hauv qab thiab cov insulators - yog kwv yees li 40% sib dua li cov hlau, tiv thaiv corrosion tag nrho, thiab muaj hluav taws xob insulating, uas yog qhov tseem ceeb ntawm cov khoom hluav taws xob uas tsis muaj hluav taws xob yuav tsum tau tswj xyuas. Lawv lub peev xwm qis dua txwv lawv rau kev tsheb ciav hlau thiab kev thauj mus los hauv nroog. Hlau tseem yog qhov kev xaiv rau mining thiab freight vim hais tias tsuas yog steel nqa 30t + qag loads nrog ib tug txaus qaug zog lub neej, thiab nws cov nqi pib dua yog rov qab los nyob rau hauv ib tug ntev kev pab cuam lub neej nyob rau hauv nruab nrab climates. Hauv kev xyaum, cov tshuab mining siv cov hlau rau kev thauj khoom thiab cov khoom sib xyaw tsuas yog rau kev rwb thaiv tsev thiab tsis yog - cov khoom siv.
Npaj rau Kev Hloov
Vim hais tias hnav nyob rau hauv ib puag ncig tsuas yog tsis muaj kev zam, cov neeg ua haujlwm yuav tsum npaj kom nrawm hloov lub voj voog ntawm 5-7 xyoo ntawm huab cua- ntu hnav, piv nrog 10-20 xyoo ntawm txoj kab ncaj nraim. Lub voj voog luv luv ntawm cov nkhaus ntse, ntawm kev hloov pauv thiab qhov twg cov plua plav ingress phem tshaj plaws. Lub tswv yim ntawm kev yuav khoom yog los npaj cov khoom siv - clips, bolts, pads thiab insulators loj rau cov kev tsheb ciav hlau tshwj xeeb - yog li cov hnav fastening tuaj yeem hloov tau raws li cov txheej txheem es tsis yog piecemeal, ua kom clamping quab yuam sib xws ntawm txoj kev tsheb ciav hlau.
Cov lus nug nquag
Dab tsi bolt loj li mining fastening tshuab siv?
Tus qauv tsim rau lub luag haujlwm hnyav mining yog M24 thiab siab dua, nrog rau cov xov suab thiab qib sib tw rau lub zog clamping xav tau rau lub qag load. Cov bolts me tsuas yog siv rau hauv kev lag luam teeb pom kev zoo.
Vim li cas mining fastenings xav tau cov pob qij txha kaw?
Plua plav packing rau hauv lub rooj zaum clip los yog ntsia liaj qhov rooj xov yuav txo cov clamping quab yuam thiab ua raws li ib tug abrasive rau txheej. Cov pob qij txha kaw kom cov chaw ua haujlwm huv si kom lub zog clamping nyob ntawm tus nqi tsim.
Ntev npaum li cas cov mining fastenings yuav tsum tau ntxuav?
Compressed - huab cua tu yog teem caij raws li cov plua plav load - ntawm cov thee thiab ore kab, feem ntau nrog rau txhua qhov tamping lossis tshuaj xyuas lub voj voog. Lub hom phiaj yog txhawm rau tiv thaiv cov plua plav tsim- nyob ib ncig ntawm cov ko taw thiab lub hnab ris.
Puas muaj kev sib txuas fastenings lis mining qag loads?
Tsis yog. Composite baseplates tsis muaj peev xwm thauj khoom rau 30t + qag loads thiab raug txwv rau kev tsheb ciav hlau thiab tsheb thauj mus los hauv nroog. Cov kab mining siv cov hlau thauj khoom nrog cov khoom sib xyaw tsuas yog rau kev rwb thaiv tsev.
Dab tsi yog qhov kev pab cuam lub neej ntawm mining fastening set?
Ntawm qhov tsis txaus ntseeg - hnav ntu, 5-7 xyoo yog daim duab npaj tiag tiag. Lub neej tiag tiag nyob ntawm lub qag load, nkhaus vojvoog, plua plav hnyav thiab kev saib xyuas, thiab yuav tsum tau taug qab los ntawm cov ntaub ntawv tshuaj xyuas.
