Ib txoj hlua hlau yog cov khoom siv kho tshuab tsim los ntawm kev sib tw ntau cov hlua ntawm cov hlau xaim rau hauv cov hlua, uas tom qab ntawd twisted nyob ib ncig ntawm ib qho tseem ceeb (feem ntau 6 strands). Nws ua hauj lwm raws li ib qho tseem ceeb tsis tau yooj yim load-cov kabmob hauv kev lag luam niaj hnub, feem ntau hu ua "cov hlab ntsha ntawm kev lag luam." Txawm li cas los xij, thaum lub sij hawm siv tiag tiag, thaum cov hlua hlau pom cov hlau tawg, hnav, corrosion, deformation, txoj kab uas hla txo, lossis thermal puas, lawv yuav tsum tau hloov nrog cov tshiab los xyuas kom meej tias lawv muaj kev nyab xeeb thiab kev ntseeg tau.
Yog li ntawd, thaum yuav cov hlua hlau, ntau tus neeg siv khoom xav kom ncua kev pab cuam lub neej thiab txo cov nqi los ntawm kev tau txais thiab siv cov hlua ruaj khov. Tab sis dab tsi yog qhov zoo tshaj plaws hlau hlua? Kev ntsuam xyuas cov hlua hlau lub zog feem ntau suav nrog kev soj ntsuam cov yam ntxwv xws li kev tawg lub zog, kev puas tsuaj, kev tiv thaiv corrosion, kev qaug zog, thiab kev ua haujlwm ntev.
Txhawm rau txiav txim siab seb txoj hlua hlau puas ruaj khov, koj tuaj yeem tsom mus rau cov yam ntxwv tseem ceeb hauv qab no:
Txoj kab uas hla:Nominal txoj kab uas hla, lub hauv paus rau kev txiav txim siab load -bearing peev.
Qauv:eg, 6 × 36 WS, 8 × 19S, 35W × 7. Thawj tus lej qhia cov xov tooj ntawm cov strands, tus lej thib ob qhia cov xov tooj ntawm ib txoj hlua, thiab tsab ntawv qhia txog qhov nteg.
Qib Qib:Lub nominal tensile lub zog ntawm steel hlau, ntsuas hauv MPa. Cov qhab nia muaj xws li 1770, 1870, 1960, thiab 2160. Tus lej siab dua qhia tias muaj zog tawg ntau dua rau cov hlua hlau.
Twist kev taw qhia
Interlacing twist: Txoj kev sib tw ntawm txoj hlua thiab cov hlua yog qhov sib txawv. Feem ntau siv, resistant rau loosening, thiab nthuav tawm tsis tshua muaj rotational tendency.
Unidirectional twist: Txoj kev sib tw ntawm txoj hlua thiab cov hlua yog tib yam. Nws muaj qhov yooj yooj yim tab sis nws yooj yim rau twisting thiab loosening.
Deg mob
Smooth tiav: Haum rau qhov chaw ib puag ncig.
Galvanized: Muab faib ua qib A / B / C, haum rau corrosive ib puag ncig.
Plastic txheej: Siv cov txheej yas rau sab nrauv ntawm cov hlau xaim hlua rau kev tiv thaiv corrosion, hnav tsis kam, thiab tiv thaiv nto.
Hlau ropes yog engineering crystallization ntawm lub zog thiab kev zoo nkauj. Xaiv qhov yog ib qho kos duab ntawm kev sib npaug, yuav tsum tau ua kom pom kev sib xyaw ua ke ntawm lub zog, yoog raws, hnav tsis kam, corrosion kuj, thiab tus nqi. Tsis muaj txoj hlua "zoo tshaj"; tsuas yog ib qho "zoo tshaj plaws" rau kev ua haujlwm tshwj xeeb. Kev xaiv kom raug, kev teeb tsa tus qauv, thiab kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yog lub neej ua haujlwm kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov hlua hlau.
