Anti Rotation Ntawm Hlau Hlau Rau Rope Ua
Feb 02, 2022| Thaum lifting lub load, yog hais tias lub steel hlau rau txoj hlua ua tsis tig ib ncig ntawm lub longitudinal axis los yog yuav luag tsis tig nyob ib ncig ntawm lub longitudinal axis, steel hlau rau txoj hlua ua yog steel hlau rau tsis tig txoj hlua ua. Cov yam ntxwv no yog tshwm sim los ntawm qhov opposite torsion kev taw qhia ntawm lub puab thiab sab strands. Thaum lub load yog thov mus rau lub tsis rotating hlua ua steel hlau, lub torque generated los ntawm cov hlua core yog opposite rau uas generated los ntawm sab nraud hlua strand, thiaj li mus tsim ib tug tshuav nyiaj li cas.
Lub steel hlau rau txoj hlua ua yog tus cwj pwm los ntawm:
1. Thaum txoj hlua yog loaded nrog steel hlau, nws rotates me ntsis los yog tsis muaj kiag li.
2. Cov hlua hlau hlau muaj zog ua haujlwm siab.
3. Cov hlua hlau hlau yog hloov tau thiab yooj yim rau kev khiav lag luam.
4. Rotational stability.
Nyob rau hauv ib txoj hlua hoisting system, thaum qhov hnyav ntawm cov hlau hlau rau txoj hlua ua tsis quav ntsej, kev sib hloov ntawm cov hlua hlau hlua yog ncaj qha proportional rau qhov ncua kev kawm ntawv ntev ntawm cov hlau hlau hlua.
Ob lub elongated steel hlau rau txoj hlua ua
Thaum cov hlau xaim rau txoj hlua ua yog raug rau tensile load, nws yuav ncab nyob rau hauv ntau theem. Pre tensioning ntawm steel hlau hlua ua ntej siv yog ib tug txhais tau tias kom tshem tawm nws cov qauv elongation.
Muaj ntau yam ua rau elongation ntawm steel hlau rau txoj hlua siv, thiab qhov elongation tshwm sim los ntawm qee yam me me thiab tuaj yeem tsis quav ntsej. Feem ntau, cov laj thawj tseem ceeb ntawm txoj hlua hlau elongation yog raws li hauv qab no, ntawm cov thawj ob yog qhov tseem ceeb tshaj.
1. Cov qauv elongation: qhov elongation tshwm sim los ntawm txoj hauj lwm hloov ntawm txhua cov hlau hlau thiab steel hlau rau txoj hlua ua; elongation tshwm sim los ntawm qhov nce ntawm qhov sib nrug los ntawm kev sib hloov dawb ntawm ib kawg ntawm cov hlua hlau hlau; Qhov ntxiv elongation tshwm sim los ntawm kev txo cov hlau cheeb tsam ntawm cov hlau hlau hlua uas tshwm sim los ntawm kev hnav ntawm cov hlau hlau sab hauv yog sib sau ua ke hu ua structural elongation.
2. Elastic elongation: lub elongation ntawm cov khoom nyob rau hauv lub elastic ntau yam vim lub thib ob tensile load.
3. Yas elongation: lub sij hawm ntev thiab inelastic elongation tshwm sim los ntawm kev thauj khoom tshaj qhov taw tes tawm ntawm cov khoom.
4. Kub: elongation los yog shortening tshwm sim los ntawm kub hloov.
