Waa maxay cabbirrada unugyada iftiinka calaamaduhu?

Calaamadaha gaadiidkasi sharci ah ayay u xidhan yihiin calaamado iftiin ah oo u sheega baabuurta iyo dadka lugaynaya inay sii socdaan ama ku istaagaan wadooyinka. Waxa ugu horrayn loo kala saaray sida nalalka signalada, laydhka haadka, iyo nalalka lugaynta. Nalalka ishaadu waa aalado muujiya calaamadaha taraafig iyagoo isticmaalaya isku xigxiga nalalka casaanka, jaalaha ah iyo cagaarka. Wadamada aduunka ayaa si cad u qeexay oo inta badan la mid ah xeerarka macnaha midabada kala duwan ee nalalka calaamadaha. Cabbirrada unugga iftiinka signallada ayaa lagu heli karaa saddex cabbir: 200mm, 300mm, iyo 400mm.

Dhexroorka godadka dhejinta ee unugyada iftiinka cas iyo cagaarka ee guryaha calaamaduhu waa 200mm, 290mm, iyo 390mm, siday u kala horreeyaan, oo leh dulqaad ± 2mm.

Nalalka calaamadaha aan qaabaysan lahayn, dhexroorrada dusha iftiinka iftiiminaya ee cabbirrada 200mm, 300mm, iyo 400mm waa 185mm, 275mm, iyo 365mm, siday u kala horreeyaan, oo leh dulqaad ± 2mm. Nalalka calaamadaha leh qaababka, dhexroorka wareegyada wareegsan ee meelaha iftiinka soo baxaya ee saddexda tilmaamood ee Φ200mm, Φ300mm, Φ400mm waa Φ185mm, Φ275mm, Φ365mm, siday u kala horreeyaan, iyo dulqaadka cabbirku waa ± 2mm.

Waxaa jira noocyo badan oo caan ahnalalka calaamada casaanka iyo cagaarkagudaha Qixiang, oo ay ku jiraan nalalka baabuurta, nalalka baabuurta aan mootada ahayn, nalalka isgoysyada dadka lugaynaya, iwm. Marka loo eego qaabka nalalka calaamadaha, waxaa loo qaybin karaa nalalka tilmaamayaasha, nalalka digniinta biligleynaya, isku-dhafka nalalka, iwm.

Marka xigta, dhererka rakibaadda ee noocyada kala duwan ee nalalka calaamadaha ayaa la soo bandhigay.

1. Nalalka isgoysyada:

Dhererku waa inuu ahaadaa ugu yaraan 3 mitir.

2. Nalalka isgoysyada dadka lugeynaya:

Ku rakib dhererka 2m ilaa 2.5m.

3. Nalalka haadka:

(1) Dhererka rakibaadda waa 5.5m ilaa 7m;

(2) Marka lagu rakibo marin-dhaafka ah, waa inuusan si aad ah uga hooseynin nadiifinta buundada.

4. Nalalka calaamada haadka baabuurta ee aan mooto lahayn:

(1) Dhererka rakibaadda waa 2.5m ~ 3m. Haddii tiirka ishaarka gaadhiga aan mooto lahayni uu yahay mid caarad leh, waa in uu waafaqo shuruudaha qaranka ee 7.4.2;

(2) Dhererka qaybta cantilever ee nalka calaamada gaadhiga aan mooto lahayn waa in uu xaqiijiyaa in nidaamka nalka gaadhiga aan mooto lahayn uu ku yaalo meel ka saraysa haadka bartilmaameedka gaadhiga.

5. Nalalka baabuurta, tilmaamayaasha jihada, nalalka digniinta biligleynaya iyo nalalka isgoysyada:

(1) Soosaarayaasha boodhadhka badbaadada gaadiidka waxay isticmaali karaan ugu badnaan dhererka rakibaadda cantilever ee 5.5m ilaa 7m;

(2) Markaad isticmaalayso rakibaadda tiirka, dhererku waa inuusan ka yarayn 3m;

(3) Marka lagu rakibo jirka buundada ee dulmarta, waa inuusan ka hooseynin nadiifinta jirka ee buundada;

(4) Dhererka ugu badan ee qaybta cantilever waa in aanay dhaafin xarunta maamulka haadka ugu hooseeya, dhererka ugu yarna waa inuusan ka yarayn xarunta koontaroolka haadka dibadda.

Qixiang waxa uu leeyahay in ka badan toban sano oo waayo-aragnimo ah oo ku saabsan nalalka signalada iyo waxa uu leeyahay awood sare nalalka signalada, nalalka signal hooseeya,nalalka calaamadaha lugaynta isku dhafan, Nalalka iftiinka qoraxda, nalalka mobile-ka, iwm. Habka ugu fiican ee lagu dooran karo alaabooyinka waa in si toos ah loo aado wax-soo-saarka jumlada iyada oo aan ka welwelin dammaanadda adeegga iibka kadib. Waa lagugu soo dhawaynayaa inaad u timaaddo kormeer goobta ah.
