Kukonza Uinjiniya wa Magalimoto Otsika a Zitsulo Zolemera a Tunnel Trestle Systems

Pa ntchito zazikulu za ngalande zodutsa mitsinje kumpoto kwa China, magulu omanga amafunikira chida cholemera chogwirira ntchito za ngalande chomwe chimagwirizana ndi trolley yachiwiri komanso makina obowolera ngalande. Chopangidwa kuti chigwire ntchito yonyamula katundu wopitirira matani 25, chida ichi chiyeneranso kuyenda nthawi zambiri m'malo onyowa komanso amatope, kuphatikizapo magawo okhala ndi mipata yotsetsereka.

Mavuto aukadaulo

Pa nthawi yokonza mapulani, gulu la polojekitiyi linathetsa mavuto angapo akuluakulu a uinjiniya:

1. Kutha Kunyamula Pansi Kosiyanasiyana:Madzi ndi matope ofewa omwe amasonkhana pafupipafupi pansi pa ngalandeyi amafuna chassis yokhala ndi mphamvu yochepa pansi kuti athetse chiopsezo cha kugwa pansi pa katundu wolemera.

2. Kutopa Kwambiri Chifukwa cha Kulemera Kwambiri, Kozungulira: Chitsulo cha trestle chiyenera kupirira kupsinjika mobwerezabwereza panthawi yoyenda mosalekeza. Kapangidwe ka chitsulo cha carbon chokhazikika kamakhala ndi vuto la kutopa pansi pa mikhalidwe iyi.

3. Malo Ogwirira Ntchito Okhala ndi Malo Ocheperako: Mbiri ya ngalande yopapatiza imafuna njira yoyendera yomwe imatha kuyika malo molondola komanso kuyendetsa modalirika komanso mwachangu kwambiri ikanyamula katundu wambiri.

Yankho laukadaulo

Pofuna kuthana ndi mavutowa, gulu laukadaulo la YIKANG linapanga njira yoyendetsera zinthu pogwiritsa ntchito chitsulo, yokhala ndi zinthu zatsopano zotsatirazi:

1. Kapangidwe ka Kapangidwe ndi Kukhulupirika kwa Zinthu

Chimango chachikulu cha pansi pa galimoto yonyamula katundu chimapangidwa ndi chitsulo champhamvu cha Q355D, chomwe chimapereka mphamvu yochuluka yogwira ntchito ndi pafupifupi 40% kuposa zinthu wamba za Q235. Finite Element Analysis (FEA) inali yofunika kwambiri pa kapangidwe kake, kutsogolera kulimbitsa kwanzeru pamalo ovuta kwambiri kuti zitsimikizire kuti chitetezo chili bwino ngakhale patakhala matani 25-30.

2. Akatswiri Owotcherera ndi Kupanga Zinthu

Popeza kufunika koteteza n’kofunika kwambiri, ma weld onse ofunikira ankachitika pamanja ndi akatswiri odziwa bwino ntchito zolemera kwa zaka zoposa khumi.

• Njira Yolamulidwa:Njira yokhwima yogwiritsira ntchito kutentha kwa magawo ambiri komanso kuwotcherera kwa mitundu yosiyanasiyana kumatsimikizira kusakanikirana kwathunthu kwa mizu.

• Kutsimikizira Kokhwima:Chosefera chilichonse chimayesedwa ndi 100% Visual Test (VT), chowonjezeredwa ndi Ultrasonic Testing (UT) pa makiyi olumikizirana. Izi zimathandiza kuti pasakhale zolakwika zamkati—monga ma porosity kapena ming'alu—kuti pakhale kukana kwakukulu kwa kukhudza.

3. Kuyendetsa Bwino ndi Magwiridwe Abwino

• Kupanikizika Kwambiri kwa Pansi:Nsapato zotambalala komanso mawonekedwe abwino a roller zimapangitsa kuti mphamvu ya pansi ikhale yotsika kwambiri pa ≤55 kPa, zomwe zimathandiza kuti ntchito ikhale yodalirika m'malo ofewa komanso amatope.

• Mphamvu Yogwira Ntchito Kwambiri:Dongosolo loyendetsera ma hydraulic lomwe lili ndi mabuleki okhazikika, limaonetsetsa kuti malo ake ali bwino komanso kuti ayambe bwino pamalo otsetsereka.

Zotsatira za Ntchito

Kwa miyezi yoposa 12 yogwira ntchito mosalekeza kuyambira pomwe idayikidwa, chassis yapereka kudalirika kwakukulu ndi zotsatira zotsatirazi:

• Ntchito Yosasokonezedwa:Sitinapeze nthawi yopuma yogwiritsira ntchito makina oyendera nthawi yonse yoyambira ntchito ya ngalande, zomwe zinathandiza kuti ntchitoyo ichitike bwino panthawi yake.

• Kulimba Kotsimikizika:Kuyeza kwa malo kumatsimikizira kuti kuchuluka kwa nsapato zoyendera ndi zothandizira zoyendera m'malo okhala ndi miyala yolimba ndi kotsika kwambiri kuposa momwe akuyembekezeredwa, zomwe zimapangitsa kuti moyo wautumiki ukhale wokwera ndi 60%.

• Chitetezo Chowonjezereka Pamalo Ogwirira Ntchito:Kapangidwe kabwino kwambiri, kotsika pakati pa mphamvu yokoka kathandiza kwambiri kukhazikika kwa mbali ya thupi panthawi yoyendetsa zida, zomwe zawonjezera chitetezo cha ntchito.

Pulojekitiyi ikutsimikizira kuti pa ntchito zomangamanga zoopsa komanso zodzaza katundu monga ma tunnel trestles, yankho lopangidwa mwamakonda nthawi zonse limagwira ntchito bwino kuposa chinthu chomwe sichinagwiritsidwe ntchito kale. Kudzera mu kuwongolera mosamala kusankha zinthu, luso lowotcherera, ndi makina omangira, YIKANG yapereka bwino maziko olimba komanso olimba a zida zofunika kwambiri za tunnel.
