Ukwenziwa ngcono kobunjineli beemoto ezingaphantsi kweTrack yentsimbi enzima kwiinkqubo zeTunnel Trestle

Kwiiprojekthi ezinkulu zemijelo enqumla imilambo emantla eTshayina, amaqela okwakha afuna i-trestle yemijelo enzima ehambelana netroli yesibini kunye nomatshini wokubhoboza imijelo. Yenzelwe ukusingatha imithwalo enamandla edlula iitoni ezingama-25, le trestle kufuneka ikwazi ukuhamba rhoqo kwiimeko zemijelo emanzi, enodaka, kuquka neendawo ezineeshafti ezithambekileyo.

Imingeni yoBugcisa

Ngexesha lesigaba soyilo, iqela leprojekthi lijongene nemingeni emininzi ebalulekileyo yobunjineli:

1. Umthamo wokuthwala umhlaba oguquguqukayo:Ukuqokelelwa rhoqo kwamanzi nodaka oluthambileyo kumgangatho wetonela kwakufuna itshasi enoxinzelelo oluncinci lomhlaba ukuze kuthintelwe umngcipheko wokuncipha phantsi kwemithwalo enzima.

2. Ukudinwa kolwakhiwo oluvela kumthwalo onzima nojikelezayo: I-chassis ye-trestle kufuneka inyamezele uxinzelelo oluphindaphindeneyo ngexesha lokuhamba okuqhubekayo. Izakhiwo zentsimbi yekhabhoni eziqhelekileyo zinokuba nokuqhekeka kokudinwa phantsi kwezi meko.

3. Indawo Yokusebenzela Exineneyo Kakhulu: Iprofayili yomngxuma omxinwa ifuna inkqubo yokuhambahamba ekwaziyo ukubeka indawo ngokuchanekileyo kunye nokuqhuba okuthembekileyo, okukhawulezayo ngelixa iphantsi komthwalo opheleleyo.

Isisombululo soBugcisa

Ukuze kujongwane nale mingeni, iqela lobuchwephesha le-YIKANG lenze isisombululo sokuhamba esenziwe ngokwezifiso esilandelwa ngentsimbi, esinezinto ezintsha ezilandelayo:

1. Amandla oLwakhiwo kunye noBuchule beZinto

Isakhelo esiphambili sendlela engaphantsi kwesithuthi sakhiwe ngentsimbi enamandla aphezulu ye-Q355D, enika amandla okuvelisa angaphezulu nge-40% kunezixhobo eziqhelekileyo ze-Q235. Uhlalutyo lweFinite Element (FEA) lwaluyinxalenye ebalulekileyo yoyilo, lukhokela uqiniso olucwangcisiweyo kwiindawo ezibalulekileyo zoxinzelelo ukuqinisekisa umda wokhuseleko oqinileyo phantsi kwemithwalo enzima yeetoni ezingama-25-30.

2. Iingcali zokuWelda kunye nokuFaka

Ngenxa yeemfuno zokhuseleko ezibalulekileyo, zonke ii-weld ezibalulekileyo zenziwe ngesandla ngabawelda ababalaseleyo abagxile kwizixhobo ezinzima kangangeminyaka engaphezu kweshumi.

• Inkqubo eLawulwayo:Inkqubo engqongqo equka ukufudumeza kwangaphambili okunezigaba ezininzi kunye nokuwelda okunezingqimba ezininzi kuqinisekisa ukuhlanganiswa kweengcambu ngokupheleleyo.

• Ukuqinisekiswa Okungqongqo:I-weld nganye idlula kwi-100% Visual Testing (VT), eyongezwa yi-Ultrasonic Testing (UT) kwiindawo eziphambili zokudibanisa. Oku kuqinisekisa ukuba akukho ziphene zangaphakathi—ezifana nokuqhekeka okanye ukuqhekeka—ukuze kuxhathiswe impembelelo engcono.

3. I-Optimized Drive kunye ne-Performance

• Uxinzelelo Lomhlaba Oluphantsi Kakhulu:Izihlangu ezibanzi kunye noqwalaselo lwerola olucwangcisiweyo zigcina uxinzelelo lomhlaba kwi-≤55 kPa, nto leyo evumela ukusebenza okuthembekileyo kwiimeko ezithambileyo nezinodaka.

• Ukutsala Okunamandla Okuphezulu:Inkqubo yokuqhuba i-hydraulic edibeneyo ine-braking ezenzekelayo, iqinisekisa indawo ezinzileyo kunye nokuqala okuthambileyo kwiindawo ezithambekileyo.

Iziphumo Zokusebenza

Kwiinyanga ezili-12 zokusebenza okuqhubekayo ukusukela oko kwasetyenziswa, itshasi inikezele ngokuthembeka okugqwesileyo kunye neziphumo ezilandelayo ezibonisiweyo:

• Umsebenzi ongenaziphazamiso:Ifikelele kwixesha lokungasebenzi ngokupheleleyo kwenkqubo yokuhambahamba kuyo yonke inqanaba lokuphumelela kwetonela, ixhasa ngokuthe ngqo ukugqitywa kweprojekthi ngexesha elifanelekileyo.

• Ukuqina Okuqinisekisiweyo:Ukulinganiswa kwentsimi kuqinisekisa ukuba amazinga okuguguleka kwezihlangu zomkhondo kunye neerola zokuxhasa kwiimeko zelitye elirhabaxa aphantsi kakhulu kunokuba bekulindelwe, nto leyo eyandisa ubomi benkonzo obuqikelelweyo ngama-60%.

• Ukhuseleko Oluphuculweyo Kwindawo:Uyilo olucwangcisiweyo, oluphakathi nendawo yomxhuzulane oluphantsi luphucule kakhulu uzinzo olusecaleni ngexesha leentshukumo zokulwa, nto leyo eyandisa ukhuseleko lokusebenza.

Le projekthi iqinisekisa ukuba kwizicelo zeziseko zophuhliso ezinomngcipheko ophezulu nezinomthwalo omkhulu ezifana nee-tunnel trestles, isisombululo esenziwe ngokwezifiso sihlala siphumelela ngaphezu kwemveliso engasetyenziswanga. Ngokulawula ngononophelo ukukhethwa kwezinto, ubuchule bokudityaniswa, kunye noomatshini bolwakhiwo, i-YIKANG iphumelele ukubonelela ngesiseko sombane esomeleleyo nesihlala ixesha elide kwizixhobo ze-tunnel ezinzima ezibalulekileyo.
