7×7 Chingwe cha waya
- Kuzenga: Vingwe 7, chingwe chilichose chikupangika na mawaya ghachokoghachoko 7 gha visulo
- Mawaya ghose: 49 mawaya ghamoza
- Chinthu: Mawaya ghakukhora mukati mwa vingwe, kapangikiro kakukhora, kusinthasintha
7×19 Chingwe cha waya
- Kuzenga: Vingwe 7, chingwe chilichose chikuzungulirika na tumawaya tuchokotuchoko 19 twa visulo
- Mawaya ghose: 133 mawaya ghamoza
- Chinthu: Mawaya ghachoko waka mukati mwa vingwe, ghakufewa, ghakusinthasintha chomene
Kuyezgelera Nkhongono zakuphwanya (Kuyana Kwakuyana & Mtundu wa Vinthu)
Pansi pa chingwe chakuyana waka, chitsulo, mtundu wa tensile na kupanga: 7 × 7 waya chingwe chili na katundu wakuphwanya wakukwera (wankhongono) kuluska 7 × 19.
Chifukwa:
1. Kupambana kwa waya umoza
× 7 wakugwiriskira ncito mawaya gha visulo ghakukhozga gha munthu payekha. Waya wakukhora wakunyamura nkhongono yikuru ya kukhozga pa waya, na kutayika kwakukhwaskana pakati pa mawaya ghamukati.
× 19 wakuzomerezga mawaya ghawemi chomene; mfundo zinandi zakukhwaskana na waya zikupanga mphindano zikuru za mukati pasi pa mphindano, kuchepeska nkhongono zose zakusweka.
2. Mtanda-chigaŵa malo ghakugwira ntchito gha visulo
Pa diameter yakunja yakuyana, 7 × 7 yikuleka mipata yichoko pakati pa mawaya ghakukhora, ndipo ivi vikupangiska kuti paŵe chigaŵa chikuru cha mtanda wa chisulo -. Malo ghakuru gha visulo mwachindunji ghakupangiska kuti nkhongono ya kuswa ya tensile yiŵe yiwemi.
Chiyelezgero cha Data Referensi (304 chingwe cha waya wa zitsulo zambura zimbiri, Ø3mm):
× 7 Ø3mm: Min kuphwanya katundu ≈ 880 kgf
× 19 Ø3mm: Katundu wakuphwanya ≈ 720 kgf
Nkhongono zakugwiriskira ncito na Nkhongono
Sankhani 7×7 (Nkhongono yakukhora chomene, yakukhora)
Kukhoma kwakukhazikika, waya wa munthu, khebo ya guardrail
Kukwezga kwakufupi-kuchepa-kukwezga pafupipafupi, kukhoma kwakunyoloka kwambura kupindika pafupipafupi
Makhebo ghakulongozgera ghakukhora, ghakukhozga mwakuvikilirika na katundu wakukhumbikwa chomene
Sankhani 7 × 19 (Nkhongono yakukhora ya pasi, yakusinthasintha chomene)
Kukwezga crane, chingwe cha winch, waya wakulongozgera lifiti
Vingwe vyakujumpha mu pulleys, kukhotakhota pafupipafupi & kukhotakhota mwakuwerezgawerezga
Kupanga vinthu vya mu nyanja, makhebo ghakutumizgirako makina ghakusinthasintha
Vikumbusko vyakuzirwa vyakusazgikira
- Usange vingwe viŵiri ivi vikupambana mu diameter: Diameter yikuru nyengo zose yili na nkhongono zakuswa zapachanya, izo zikuluska nkhongono ya 7 × 7.
- 316 chisulo chambura zimbiri, chisulo cha carbon chakupangika na galvanized, chisulo chapachanya-tensile alloy chikusintha nkhongono chomene kwambura kupwelerako za kuzenga.
- Kugwira ntchito katundu chitetezo chifukwa: Nangauli 7 × 7 ndi wankhongono, katundu weneco wakugwira ntchito wakwenera kusunga chitetezo cha 5 ~ 10 nyengo kulemera kwakugwira ntchito, mungagwiriskira ncito yayi katundu wakuswa nga ni katundu wakuzomerezgeka.
Na diameter yimoza na vinthu vyachisulo:
Nkhongono yakukhora:7×7 > 7×19
Kusinthasintha & kukhoma umoyo wa kutopa:7×19 > 7×7
Kusankha logic: Kuŵika pakwamba 7 × 7 kwa kukhazikika kwakukhozga; sankhani 7 × 19 kwa nkhongono kukhota & kukhotakhota ntchito mikhaliro.
