Hlau Ropes Rau Choj Crane / Gantry Cranes

Hlau Ropes rau Choj Crane / Gantry Crane

 

Cov hlua hlau steel muaj lub zog siab, lub teeb yuag, zoo yoog raws, cuam tshuam tsis kam, kev nyab xeeb thiab kev ntseeg tau. Cov hlua hlau siv nyob rau hauv cov xwm txheej ib txwm yuav tsis tawg tam sim ntawd, tab sis nws yuav raug puas tsuaj vim lub load tshaj nws qhov kawg tawg quab yuam.

 

Muaj cov precursors rau kev puas tsuaj ntawm cov hlua hlau, uas ib txwm pib los ntawm cov hlau tawg, thiab tam sim ntawd tawg ntawm tag nrho cov hlua tsis tshua muaj tshwm sim. Hlau hlua yog dav siv nyob rau hauv cranes. Kev puas tsuaj ntawm cov hlua hlau yuav ua rau muaj qhov tshwm sim loj heev, yog li txoj hlua hlau tsis yog tsuas yog ib qho tseem ceeb ntawm cov tshuab hoisting, tab sis kuj yog qhov txuas tseem ceeb los xyuas kom muaj kev nyab xeeb ntawm kev ua haujlwm hoisting.

 

1. Cov qauv ntawm cov hlua hlau
 

Cov hlua hlau hlau yog twisted rau hauv cov hlua los ntawm ntau txheej steel hlau, thiab tom qab ntawd muab tso rau ntawm cov hlua hlua, twisted rau hauv ib txoj hlua helical los ntawm qee tus xov tooj ntawm cov hlua.
 

(1) steel hlau
 

Lub steel hlau hlua plays lub luag hauj lwm ntawm bearing lub load, thiab nws cov kev ua tau zoo yog txiav txim siab los ntawm steel hlau. Hlau hlau yog ib puag ncig (los yog tshwj xeeb-puab) hlau ua los ntawm cov hlau los yog hlau hlau los ntawm kev kos duab txias lossis txias dov. Nws muaj lub zog siab thiab toughness, thiab kev kho saum npoo ntawm cov hlau hlau yog ua raws li qhov sib txawv ntawm ib puag ncig.

 

(2) hlua core
 

Nws yog siv los ua kom cov elasticity thiab toughness ntawm steel hlau ropes, lubricate tooj liab xov hlau, txo kev sib txhuam, thiab ua kom lub neej kev pab cuam.
 

Cov ntaub ntawv xws li cov organic fibers (xws li hemp thiab paj rwb), hluavtaws fibers, asbestos cores (qhov kub thiab txias) los yog cov hlau mos feem ntau yog siv rau cov hlua cores.

 

 

2. Hom hlua hlau
 

Lub steel hlau hlua rau cranes txais ob-twisted multi-strand round steel hlau hlua.
 

(1) Raws li lub xeev kev sib cuag ntawm cov hlau xaim, nws tuaj yeem muab faib ua cov ntsiab lus sib cuag, kab sib cuag thiab qhov chaw sib cuag hlau hlua.

 

① Point contact wire rope (tseem hu ua hom zoo tib yam) yog twisted nrog steel hlau ntawm qhov sib npaug ntawm txoj kab uas hla.
 

Vim tias qhov sib nrug deb ntawm txhua txheej ntawm cov hlau hlau tsis sib npaug, kev sib cuag taw tes yog tsim los ntawm txhua txheej ntawm cov hlau hlau thiab hlau hlau. Thaum thauj khoom, kev sib cuag ntawm cov hlau hlau yog siab heev, nws yooj yim rau hnav thiab tawg, thiab kev pabcuam lub neej yog tsawg. Qhov zoo dua yog tias cov txheej txheem tsim khoom yog yooj yim thiab pheej yig.
 

Point contact wire ropes feem ntau yog siv los ua cov hlua khi rau kev nqa cov haujlwm, thiab tseem siv rau hauv kev ua haujlwm ntawm cranes.

 

② Kab-sib cuag steel hlau ropes yog twisted nrog steel hlau ntawm txawv diameters.
 

Npaj cov hlau xaim ntawm cov txheej sab hauv thiab sab nrauv kom tsim tau ib txoj kab sib txuas ntawm cov hlau ntawm cov txheej txheem sib txawv thiab cov hlau xaim kom txo tau qhov kev sib cuag ntawm cov hlau xaim thaum thauj khoom.
 

Cov hlua khi hlua muaj peev xwm ua tau zoo, ua kom yooj yim thiab ua haujlwm ntev. Feem ntau siv kab hu xov tooj ropes xws li Searle hom (tseem hu ua cov tuab tuab), Valentun hom (tseem hu ua tuab thiab nyias hom), hom puv(tseem hu ua tuab hom) thiab lwm yam. Nyob rau hauv kev ua hauj lwm mechanism ntawm lub crane, txoj kab kev sib cuag hlau hlua yog nyiam.

 

③ Kev sib cuag nrog cov hlua hlau (tseem hu ua hom kaw).
 

Feem ntau round steel hlau yog siv los ua cov strand core, thiab txheej txheej sab nrauv los yog txheej txheej yog ua los ntawm steel hlau nrog tshwj xeeb-zoo li tus ntoo khaub lig-section. Cov khaubncaws sab nraud povtseg yog nyob rau saum npoo thiab raug mob los ntawm extrusion.
 

Nws yog characterized los ntawm du nto, zoo saj zawg zog thiab siab zog. Corrosion-resistant, tab sis cov txheej txheem tsim khoom yog qhov nyuaj thiab tus nqi siab. Nws tsis tshua muaj siv ntawm cranes. Nws feem ntau yog siv los ua cov kabmob thauj khoom ntawm cable cranes thiab aerial ropeways.

 

 

(2) Muab faib raws li cov kev taw qhia twist ntawm cov hlua hlau.
 

Raws li seb cov kev taw qhia nyob rau hauv uas cov hlua hlau yog twisted rau hauv strands yog raws li cov kev taw qhia nyob rau hauv uas strands yog twisted rau hauv ropes, nws yuav muab faib ua:

 

① Hloov txoj hlua hlua (tseem hu ua txoj hlua sib txuas).
 

Cov kev taw qhia nyob rau hauv uas cov strands yog twisted rau hauv strands yog opposite rau cov strands twisted rau hauv ropes. Txij li cov kev taw qhia ntawm txoj hlua thiab txoj hlua yog qhov sib txawv, nws tsis yooj yim rau ntswj thiab xoob thaum siv, yog li nws tau siv dav hauv cranes.

 

② Hlau ropes nteg nyob rau hauv tib txoj kev (tseem hu ua parallel winding ropes).
 

Cov kev taw qhia nyob rau hauv uas cov strands yog twisted rau hauv strands yog tib yam li cov strands twisted rau hauv ropes, thiab nws yooj thiab lub neej yog zoo dua li cov alternating twisted ropes. Txawm li cas los xij, vim nws yooj yim rau ntswj thiab xoob, nws feem ntau tsuas yog siv los ua txoj hlua traction.

 

③ Tsis txhob ntswj cov hlua hlau.
 

Thaum cov hlua zoo li no tau tsim, lub sijhawm torsional ntawm cov hlua thiab cov hlua yog sib npaug thiab cov lus qhia yog qhov sib txawv, uas kov yeej qhov tshwm sim torsion thaum siv. Nws yog feem ntau siv rau cranes nrog loj nqa qhov siab, thiab tau them nyiaj ntau thiab ntau dua.
