CovLongwall Shearer Underframe Legyog ib qho tseem ceeb ntawm cov txheej txheem uas txuas lub ntsiab lub cev ntawm cov shearer mus rau lub thauj system ntawm lub conveyor. Nws lub luag haujlwm tseem ceeb yog ua tus ncej, muab qhov tsim nyog qhov siab thiab tshem tawm rau lub tshuab kom ua haujlwm tau zoo tshaj qhov armored face conveyor (AFC). Cov ceg no tseem ua haujlwm tseem ceeb tshaj plaws rau kev thauj mus los thiab cov txheej txheem kev coj ua. Los ntawm kev txhawb nqa lub ntsiab chassis, lub hauv qab ob txhais ceg tsim qhov chaw tseem ceeb uas yuav tsum tau txiav cov thee kom hla hauv qab lub tshuab tsis ua rau muaj kev cuam tshuam los yog "cov ntsiab lus choke" uas yuav nres ntau lawm. Lawv xyuas kom lub tshuab nyob twj ywm theem thiab ua kom zoo nrog lub haulage khib tuav.
Tsim ibLongwall Shearer Underframe Legyuav tsum muaj kev nkag siab tob txog kev qaug zog ntawm cov qauv, cov khoom siv science, thiab kev faib tawm kev ntxhov siab. Raws li lub tshuab txiav los ntawm cov thee tawv thiab pob zeb, ob txhais ceg raug kev sib tw loj heev (torsional) quab yuam thiab kev thauj khoom sab nraud. Lawv feem ntau yog tsim los ntawm hnyav- phaj siab- lub zog hlau los yog tsim ua ib qho loj heev - daim castings kom tshem tawm cov vuam - cov ntsiab lus tsis muaj zog. Tus qauv tsim yuav tsum suav nrog siab - qhov tseeb mounting bores rau cov pivot pins uas txuas mus rau lub haulage units. Tsis tas li ntawd, Longwall Shearer Underframe Leg yuav tsum tau tsim nrog "ua tsis tiav- nyab xeeb" cov yam ntxwv, kom ntseeg tau tias txawm tias nyob hauv qhov hnyav dhau los, cov qauv tseem nyob ruaj khov los tiv thaiv cov neeg ua haujlwm thiab lub tshuab tseem ceeb. Kev ua tau zoo ntawm cov tshuab raug ntsuas raws li nws cov load{11}}cov kabmob muaj peev xwm, nws tsis kam rau kev vibration{12}} ua rau qaug zog, thiab nws lub peev xwm los tswj kev sib raug zoo ntau xyoo ntawm kev pabcuam.
Kev kho ntawm lubLongwall Shearer Underframe Legtsom rau kev ncaj ncees ntawm cov qauv thiab kev noj qab haus huv ntawm cov ntsiab lus sib txuas. Kev kuaj tsis tu ncua tsis tu ncua (NDT), xws li kev tshuaj xyuas ultrasonic lossis hlau nplaum, raug pom zoo kom kuaj xyuas cov kab nrib pleb hauv cov welds lossis siab - kev ntxhov siab radii thaum lub sij hawm hloov kho loj. Cov bores qhov twg ob txhais ceg txuas mus rau lub cev tseem ceeb yuav tsum tau kuaj xyuas "ovality," uas qhia tias xoob pins thiab kev txav ntau dhau. Lubrication ntawm cov ntsiab lus txuas thiab pivot pins kuj tseem ceeb heev los tiv thaiv kev sib tsoo thiab hnav. Vim tias nws yog lub hauv paus ntawm lub tshuab lub cev, ua kom Longwall Shearer Underframe Leg nyob rau hauv qhov zoo tagnrho yog qhov tseem ceeb rau kev nyab xeeb tag nrho, kev sib xyaw ua ke, thiab ntev - lub sij hawm kev cia siab ntawm tag nrho cov longwall mining system.
