I-Engle ye-Sling iwathinta kanjani amandla e-Flat Sling?

Ithimba lokugebenga liphakamisa ipuleti lensimbi lamathani angu-3 lisebenzisa imilenze emibili isihlilingi esiyisicaba . Umlenze ngamunye wendwayimane ukalwe ngamathani ama-2. Umthwalo ubonakala ungaphakathi komthamo—amathani angu-4 esewonke, akunjalo? Kodwa imilenze yendwayimane isakazwa nge-engeli engu-45°. Umphathi wokukhwabanisa uyalazi iqiniso: umlenze ngamunye manje uthwele amathani angu-2.1—udlula umthamo wawo olinganiselwe.

 

Lesi simo senzeka kaningi kunokuvuma ochwepheshe abaningi bokukhohlisa. I-engeli ye-sling ingenye yezinto ezibaluleke kakhulu—futhi evamise ukuqondwa kabi—emisebenzini yokuphakamisa ephephile.

 

I-Lishenflex  ibilokhu ikhiqiza izihlilingi zokwenziwa eziyisicaba iminyaka engaphezu kwamashumi amabili, futhi ulwazi lwethu lwasensimini lubonisa ukuthi ukubalwa kabi kwe-engeli kuyimbangela ehamba phambili yokulayishwa ngokweqile kwesihlilingi kanye nokwehluleka. Ukuqonda ubudlelwano phakathi kwe-engeli ye-sling namandla kubalulekile kuwo wonke ama-rigger, umphathi, kanye nochwepheshe bezokuphepha.

 

 

Kungani I-Sling Angle Ibalulekile

Uma isihlilingi esiyisicaba  sisetshenziswa ekuphakamiseni okuqondile, okuqondile, umthamo ophelele olinganiselwe uyatholakala. Nokho, njengoba imilenze yendwayimane ihlukaniswa—kungakhathaliseki ukuthi kubhasikidi noma ekuphakamiseni imilenze eminingi—ukungezwani emlenzeni ngamunye kuyanda. Uma i-engeli encane phakathi komlenze wesihlilingi novundlile (noma i-engeli enkulu phakathi kwemilenze), kuphakama ukungezwani.

 

Ukufakwa kwe-Wikipedia ezindwayimaneni  kuchaza ukuthi Umkhawulo Womthwalo Osebenzayo (WLL) wesihlilingi umakwe ku-sling futhi uthatha ukuphakama okuqondile. Uma isihlilingi sisetshenziswa nge-engeli, i-WLL kufanele yehliswe, futhi umthamo olinganiselwe uyancipha njengoba i-engeli phakathi kwemilenze ye-sling ikhula.

 

Izinga le-EN 1492-1  licacisa izici zokunciphisa umthamo wama-slings ayisicaba asetshenziswa ekucushweni okuhlukile kokuhitshi:

 

Umthombo: I-EN 1492-1 izici ze-sling ye-webbing flat

 

I-ASME B30.9  inikeza isiqondiso esifanayo, esidinga ukuthi amandla alinganiselwe ehliswe lapho izihlilingi zisetshenziswa kuma-engeli noma ekucushweni kwemilenze eminingi. Ngokusho kweWikipedia 'Ultraviolet' yokungena, imicu yokwenziwa efana ne-polyester nayo isengozini yokuwohloka kwe-UV ngokuhamba kwesikhathi, okungase kunciphise umthamo-ukwenza ukubala kwe-engeli kubaluleke nakakhulu kuma-slings asetshenziswa ngaphandle.

 

I-Physics ye-Sling Angle

Ubudlelwano phakathi kwe-engeli ye-sling kanye ne-tension bulawulwa ifomula elula:

 

Ukungezwani emlenzeni ngamunye = (Isisindo Somthwalo ÷ Inombolo Yemilenze) × I-Angle Factor

 

I-engeli factor ibalwa ngokuthi: 1 ÷ sin(θ) —lapho u-θ eyi-engeli ephakathi komlenze wesihlilingi kanye nendiza evundlile.

 

Umthombo: Izibalo ze-engeli ye-ASME B30.9

 

Njengoba ithebula libonisa, njengoba i-engeli iyancipha, ukungezwani emlenzeni ngamunye kukhula kakhulu. Ku-30 °, ukungezwani kuphinda kabili umthwalo oqondile emlenzeni ngamunye. Ku-10°, icishe iphindwe kasithupha umthwalo ome mpo. Lokhu kusho ukuthi isilingi esiyisicaba esingamathani angu-2 ku-30° singathwala ithani elingu-1 ngokuphephile—uhhafu womthamo walo olinganiselwe.

 

Ukuhlolwa kwelebhu ye-Lishenflex kuqinisekisa ukuthi izihlilingi ezisetshenziswa kuma-engeli angashoni ziba nengcindezi ephakeme kakhulu endaweni yokuklinywa nokunamathiselwe kweso, kusheshise ukuguga nokwandisa ingozi yokwehluleka.

 

I-Multi-Leg Slings kanye ne-Angle Factors

Uma usebenzisa izihlilingi ezinemilenze eminingi (2-leg, 3-leg, noma 4-leg), isici se-engeli kufanele sisetshenziswe emlenzeni ngamunye. Ngokusho kwe -Encyclopedia Britannica's entry on the simple machines , inzuzo yomshini we-sling ithintwa i-geometry yokuphakama-ama-engeli abanzi anciphisa amandla okuphakamisa asebenzayo.

 

Inqubo enconyiwe yokuphakamisa imilenze eminingi:

 

1. Linganisa i-engeli  phakathi komlenze ngamunye wesihlilingi novundlile.

 

2. Nquma isici se-engeli  kusuka kuthebula (1/sin θ).

 

3. Bala ukungezwani emlenzeni ngamunye = (Umthwalo ÷ Inombolo yemilenze) × I-engeli factor.

 

4. Qinisekisa ukuthi ukungezwani komlenze ngamunye  akudluli i-WLL elinganiselwe yesihlilingi.

 

Amaphutha e-Angle ajwayelekile

Amaphutha amathathu ajwayeleke kakhulu ahlobene nama-engeli ekushayeleni izihlilingi eziyisicaba yilawa:

 

1. I-Angle Ebheke Lapho Kubalwa Ingqikithi Yamandla

 

Iphutha elivamile ukungeza ama-WLL omlenze ngamunye we-sling ngaphandle kokusebenzisa ama-engeli. Ngokwesibonelo, izihlilingi ezimbili zamathani angu-2 azinikezi amathani angu-4 omthamo ku-45°—zinikeza amathani angu-2.8 kuphela (2 × 2t × 0.7 angle factor).

 

2. Ukusebenzisa I-Engeli Yereferensi Engalungile

 

Amanye ama-rigger akala i-engeli phakathi kwemilenze ye-sling kune-engeli ephakathi kwesihlilingi kanye ne-horizontal. Ithebula lesici se-engeli lisekelwe ku-engeli ukuya evundlile. I-engeli efakiwe phakathi kwemilenze iyi-engeli ephindwe kabili ukuya evundlile.

 

Ireferensi esheshayo:

 

90° kufakwe i-engeli = 45° ukuya evundlile

 

120° kufakwe i-engeli = 60° ukuya evundlile

 

30° kufakwe i-engeli = 15° ukuya evundlile

 

3. Ukunganaki Ukuncishiswa Kwekhono Kumahitshi Obhaskidi

 

Ku-basket hitches, imilenze emibili yabelana ngomthwalo, kodwa i-engeli isasebenza. Isici somthamo we-hitch kabhasikidi ene-engeli yomlenze engu-45° ngu-1.4—hhayi u-2.0. Ithebula ku-EN 1492-1 linikeza izici ezifanele.

 

Ukuhlola Nokuqinisekisa

Isiqondiso se-OSHA Ekusetshenzisweni Kwe-Safe Sling  sidinga ukuthi i-engeli yokuklinywa kanye ne-engeli yemilenze endwayimane kucatshangelwe lapho kunqunywa umthamo olinganiselwe. Ngokukhethekile, umthwalo olinganiselwe we-sling ku-hitch choke usebenza inqobo nje uma i-engeli yokuklinywa ingamadigri angu-120 noma ngaphezulu. Ukuze uthole ama-engeli of choke ngaphansi kwama-degree angu-120, umthwalo olinganiselwe kufanele uncishiswe.

 

Ngokwe- ASME B30.9 , izibalo zamandla kufanele ziqinisekiswe ngumuntu oqeqeshiwe ngaphambi kokuphakanyiswa ngakunye. Ukuhlola okuvamile kufanele kuqinisekise ukuthi amathegi endwayimane ayafundeka, njengoba i-WLL idingeka ukuze kubalwe imithwalo ephephile kuma-engeli.

 

Imibandela yokususa engukhiye ngaphansi kwe-ASME B30.9 engathinta umthamo we-engeli:

 

Umazisi ongekho noma ongafundeki—ngaphandle kwe-WLL, ukubalwa kwe-engeli ngeke kwenziwe

 

Ubufakazi bokulimala kwe-UV (ukufiphala, ukuqina)—kwehlisa amandla angaphezu kwama-engeli

 

Umonakalo obonakalayo onciphisa ububanzi obusebenzayo—okuthinta umthamo osele

 

Izincomo Ezifingqiwe Nezisebenzayo

I-engeli ye-sling ingenye yezinto ezibaluleke kakhulu ezithinta umthamo we-sling oyisicaba. I-WLL elinganiselwe ye-sling isekelwe ekuphakameni okuqondile, futhi umthamo kufanele uncishiswe uma usetshenziswa kuma-engeli.

 

Okuthathwayo okubalulekile:

 

1. Ungalokothi usebenzise isamba sama-WLL ngaphandle kokusebenzisa izici ze-engeli —ukushuba kuyanyuka njengoba i-engeli incipha

 

2. Linganisa i-engeli kokuvundlile, hhayi i-engeli phakathi kwemilenze

 

3. Bheka amathebula omthamo wobhasikidi, ukuminyanisa, nokucushwa kwemilenze eminingi

 

4. Hlola omaka bezihlilingi  ukuze uqinisekise ukuthi i-WLL ifundeka kalula—ngaphandle kwayo, izibalo zama-engeli azikwazi ukuqinisekiswa

 

5. Cabangela izici zemvelo —i-UV nokushisa kunganciphisa amandla angaphezu kwama-engeli factor

 

I-Lishenflex  ikhiqiza ama-polyester flat slings anezimpawu zomthamo ezinemibala ecacile, ethobela i-EN 1492-1 namazinga we-ASME B30.9. Sihlinzeka ngezinto eziyisethenjwa ze-engeli kanye nokuqeqeshwa okusendaweni ukuze siqinisekise ukuthi iqembu lakho lingakwazi ukubala imithwalo ephephile ngendlela efanele.
