Vim li cas Semi-trailer tawg lub Beam?
Yog vim li cas cov neeg tsim khoom
1. Inferior steel rau semi-trailer girders
Qhov ncaj ncees thiab yooj yim to taub yog vim li cas yog qhov zoo ntawm cov nqaj hlau siv los ntawm lub Hoobkas trailer tsis zoo txaus los nqa cov khoom tsim, ua rau cov nqaj tawg.
2. Txuas lub vev xaib girder
Ntxiv nrog rau kev txo qhov loj ntawm lub girder, qee cov neeg tsim khoom siv tsis zoo siv ob lub voj voog luv luv los txuas cov webs ntawm lub girder kom txuag tau tus nqi, thiab cov kabmob muaj peev xwm yog qhov phem dua li tag nrho. Cov nqaj tawg, cov neeg siv yuav tsum xyuam xim rau kev tshuaj xyuas thaum yuav lub tsheb.
3. Txo qhov loj ntawm lub girder
Qhov thib ob yog tias lub Hoobkas trailer txiav cov fab kom txuag tau tus nqi. Lub hom phiaj tseem ceeb yog txo qhov loj ntawm cov girders. Keeb kwm, muaj 14 daim hlau ntsug, tab sis lawv raug txo kom 10 tuab. Txawm li cas los xij, tus neeg siv tsis paub qhov ntawd, tab sis lawv kuj rub cov khoom raws li 14 lub peev xwm tuab. nruab nrab.
4. Vuam tsis zoo welded
Ntxiv nrog rau qhov tawg ntawm lub vev xaib, tseem muaj cov kab nrib pleb hauv cov tis qis ntawm cov girders. Muaj ob lub laj thawj tseem ceeb rau qhov no. Ib qho yog qhov teeb meem ntawm cov welder, thiab lwm qhov yog tias qhov hluav taws xob tsis ruaj khov thaum lub sij hawm vuam, thiab vuam tsis zoo.
Qhov thib ob, lub teeb lub cev dai yuav tsum tau them nyiaj ntau dua
Tseem muaj cov neeg tsav tsheb thiab cov phooj ywg uas siv lub teeb lub cev hangers kom them nyiaj tshwj xeeb. Lub teeb lub cev hangers tsis tuaj yeem overloaded, cia nyob ib leeg concentrated loads. High-strength steel beams tsis yooj yim sua thiab tsis haum rau txoj kev bumpy. Ceev faj, txwv tsis pub cov kab teeb yuav tawg. Qhov xwm txheej.
Yog vim li cas rau kev siv los ntawm cov neeg siv
1. Kev ua haujlwm vuam ntawm lub nqaj
Nws tseem yog txwv tsis pub weld ntawm lub beam ntawm semi-trailer. Tam sim no lub beam ntawm lub trailer yog feem ntau high-strength steel. High-strength steel yog ib qho yooj yim rau anneal thaum ntsib muaj zog tam sim no, thiab cov nqaj yog yooj yim tawg tom qab annealing.
2. Tshaj dhau lossis txawm tias muaj zog load
Ntxiv rau cov laj thawj saum toj no ntawm lub Hoobkas trailer, ntau cov kab tawg tawg yog tshwm sim los ntawm kev siv tsis raug ntawm cov neeg siv khoom. Feem ntau yog vim li cas yog lub sij hawm ntev overloading, uas yog yooj yim to taub. Lub peev xwm muaj peev xwm tshaj li tus nqi tsim ntawm lub trailer, thiab lub nqaj tsis tuaj yeem dais qhov hnyav ntawm cov khoom thauj, uas ua rau nws tawg. Tom qab ntawd muaj cov concentrated load, tshwj xeeb tshaj yog tam sim no nrov lub teeb lub cev trailer, lub concentrated load trailer yog ib qho yooj yim mus ua txhaum lub beam.
3. Cov girders nyob rau thaj tsam roob ris muaj zog sib tw ntau dhau
Trailers uas feem ntau khiav nyob rau hauv roob siab yog nquag ua txhaum cov girders. Lub zog torsional ntawm cov girders ntawm cov tsheb thauj khoom uas khiav hauv toj roob hauv pes yog ntau dua li cov uas khiav ntawm txoj kev tiaj tus. Cov kev qhia tshwj xeeb ntawm cov tis sab sauv thiab qis thiab cov webs ntawm cov girders yuav tsum loj dua, txwv tsis pub cov girders yuav yooj yim tawg.
