Cov kev qhia tshwj xeeb rau cov tsheb thauj khoom hauv av (LHDs) yog cov txheej txheem kev ua haujlwm uas suav nrog cov qauv hauv tebchaws, cov qauv kev lag luam, thiab cov qauv hauv pawg.Cov qauv no muab cov kev cai tshwj xeeb thiab ntau yam rau kev tsim, tsim, tshuaj xyuas, kev ua haujlwm, thiab kev nyab xeeb ntawm cov khoom siv. Nws ua hauj lwm tsis tau tsuas yog raws li lub hauv paus rau manufacturers 'cov khoom tsim thiab kev tswj kom zoo tab sis kuj raws li ib tug authoritative txoj cai rau cov neeg siv 'kev txais yuav thiab kev nyab xeeb kev ua hauj lwm.
Kev sib xyaw ntawm Technical Specification System
Cov kev specifications rau underground loaders tsis yog ib daim ntawv tab sis ib tug multi- txheej txheem txheej txheem npog tag nrho lub neej voj voog. Nws feem ntau suav nrog cov pawg hauv qab no:
1. Cov Lus Qhia Txog Kev Nyab Xeeb Kev Nyab Xeeb: Cov no yog cov kab hauv qab uas cov cuab yeej yuav tsum ua raws. GB 25518-2010 "Kev Nyab Xeeb Kev Ruaj Ntseg rau Cov Khoom Siv Hluav Taws Xob" yog tus qauv kev nyab xeeb tseem ceeb rau cov log tsheb hauv av. Rau kev taug qab thiab tsheb ciav hlau log tsheb thauj khoom, GB 25525-2010 thiab GB 25524-2010 siv raws li. Cov qauv no qhia meej txog cov kev cai tshwj xeeb thiab kev tiv thaiv kev tiv thaiv rau cov khoom siv hauv cov tshuab, hluav taws xob, hydraulics, hluav taws kub tiv thaiv, thiab ergonomics. Piv txwv li, lawv qhia meej tias cov nres nres tsheb yuav tsum tau tuav lub tsheb ntawm ib qho kev nqes hav.
2. Cov Kev Ntsuas Kev Ua Haujlwm thiab Kev Tshawb Fawb: GB / T 4652-2021 "Test Methods for Underground Mining Loaders and Loaders" muab cov qauv ntsuas kev ua tau zoo. Nws qhia txog cov xwm txheej xeem, cov txheej txheem, thiab cov txheej txheem ua cov ntaub ntawv rau cov ntsuas kev ua haujlwm tseem ceeb xws li kev sib tw, kev sib tsoo, kev tsim khoom, thiab kev ntseeg siab, kom ntseeg tau tias cov ntaub ntawv kev ua tau zoo yog kev tshawb fawb thiab sib piv, thiab ua lub hauv paus rau kev ua tiav cov khoom tiav, kev lees paub, thiab ntawv pov thawj.
3. Terminology thiab Commercial Specifications: GB/T 25604-2017 "Earthmoving Machinery - Loaders - Terminology and Commercial Specifications" standardizes the technical language and commercial descriptions in the industry, provides a clear and unambiguous base for technical exchange, cog lus, thiab kev lag luam kev lag luam.
4. Cov Lus Qhia Tshwj Xeeb rau Cov Ntsiab Lus Tseem Ceeb: Cov ncauj lus kom ntxaws ntxiv yog muab rau cov khoom tseem ceeb uas cuam tshuam rau kev ntseeg ntawm cov khoom siv. Piv txwv li, pawg txheej txheem T/QGCML 3928-2024, "Heavy-Lub Luag Haujlwm Engineering Tsheb Log rau Underground Loaders," tshwj xeeb tshaj yog cov kev cai, kev xeem, thiab kev soj ntsuam cov cai rau hnyav-duty engineering tsheb log, kom ntseeg tau lub durability ntawm cov khoom siv khiav los ntawm qhov chaw.
5. General Mechanical Safety Basics: Cov cuab yeej yuav tsum tau ua raws li cov kev cai dav dav ntawm kev nyab xeeb, xws li GB/T 25684.3-2021, "Kev Nyab Xeeb Hauv Ntiaj Teb - Kev Nyab Xeeb - Ntu 3: Cov Lus Qhia rau Loaders," uas qhia txog cov kev cai dav dav rau kev tsim kev nyab xeeb ntawm cov tsheb thauj khoom los ntawm kev pom thoob ntiaj teb.
Core Technical Requirements ntawm Specifications
Raws li ntau yam qauv, cov kev cai tseem ceeb ntawm cov kev qhia tshwj xeeb tsom rau cov hauv qab no:
1. Intrinsically Safe Design: Qhov no yuav tsum tau tshem tawm lossis txo kev pheej hmoo los ntawm kev tsim. Qhov no suav nrog kev ua kom muaj zog thiab ruaj khov, cov khoom tiv thaiv ntog (FOPS / ROPS), kev tiv thaiv zoo ntawm txhua qhov txav mus los, cov khoom siv thaum muaj xwm ceev nres, ergonomic kev khiav hauj lwm qhov chaw thiab pom, thiab tsis siv neeg nkag mus rau hauv lub xeev muaj kev nyab xeeb thaum muaj kev cuam tshuam fais fab.
2. Qhov Kev Ua Haujlwm Tseem Ceeb: Cov lus qhia meej meej tau teeb tsa rau kev ua haujlwm siab, kev cia siab, kev sib khi, thiab cov cua sov dissipation muaj peev xwm ntawm lub zog hluav taws xob (lub cav / lub cev muaj zog), kev sib kis, hydraulic system, thiab braking system (kev pabcuam thiab nres nres). Piv txwv li, hydraulic hoses yuav tsum tau haum nrog kev tiv thaiv npog nyob rau hauv ib qho kev kub ntxhov thiab kub.
3. Environmental Adaptability: Rau qhov hnyav downhole tej yam kev mob, cov specification qhia tshwj xeeb cov kev cai ntawm cov khoom tawg- pov thawj kev ua tau zoo (nyob rau hauv ib puag ncig flammable thiab explosive), corrosion kuj, plua plav cua txias system, thiab tsawg - suab nrov tsim (ua raws li GB16710.1 txwv).
4. Kev ntseeg tau thiab kev ruaj ntseg: Cov kev qhia tshwj xeeb xav kom cov cuab yeej siv lub sijhawm nruab nrab ntawm kev ua tsis tiav (MTBF) thiab qhia txog lub neej tsim ntawm cov khoom tseem ceeb. Nws kuj tseem hais txog kev tswj xyuas, xws li cov ntsiab lus saib xyuas tau yooj yim, cov cim lubrication meej, thiab cov cuab yeej nqa tau zoo.
Qhov tseem ceeb thiab kev siv cov kev qhia tshwj xeeb
Qhov tseem ceeb ntawm kev specifications ncua deb tshaj li cov khoom pov thawj. Rau cov tuam txhab tsim khoom, lawv ua haujlwm raws li "tsim phau bible" rau kev tsim khoom thiab "cov ntawv txheeb xyuas" rau kev tswj kom zoo, xyuas kom meej tias cov khoom raug cai, ua raws, nyab xeeb, thiab txhim khu kev qha. Rau cov neeg siv (cov tuam txhab mining), nws ua haujlwm raws li cov txheej txheem rau kev sib tw cov khoom siv, lub hom phiaj tus qauv rau kev lees txais, thiab cov lus qhia rau kev tshuaj xyuas txhua hnub thiab kev saib xyuas. Rau cov koom haum tswj hwm, nws yog cov cuab yeej tswj xyuas kev nyab xeeb thiab kev saib xyuas kev lag luam.
Nyob rau hauv cov kev siv, ib tug underground loader undergoes ib tug nruj txheej txheem los ntawm tsim drawings mus rau underground kev pab cuam: "tsim conformity xyuas → prototype manufacturing → hom kev soj ntsuam raws li cov qauv → tau txais ntawv pov thawj kev nyab xeeb (xws li cov mining khoom kev ruaj ntseg cim) → neeg siv raws li cov qauv.
Nyob rau hauv xaus, cov kev specifications rau underground loaders embody kaum xyoo ntawm kev lag luam kev nyab xeeb kev paub thiab kev txawj ntse. Lawv yog ib qho tseem ceeb ntawm kev sib txuas ntawm cov thev naus laus zis tshiab nrog kev ua haujlwm engineering, thiab ntsuas kev ua tau zoo nrog cov qauv kev nyab xeeb. Kev nkag siab tob thiab kev ua raws li qhov kev qhia tshwj xeeb no yog lub hauv paus ruaj khov rau kev txhawb nqa kev lag luam hauv av mus rau qib siab ntawm kev nyab xeeb, kev ntseeg siab, thiab kev txawj ntse, thiab yog ib qho tseem ceeb ua ntej kom muaj kev ruaj ntseg hauv cov mines thiab kev noj qab haus huv thiab kev nyab xeeb ntawm cov neeg ua haujlwm.
