Lub counterweight thav duab yog ua los ntawm channel steel los yog 3 ~ 5 hli steel phaj folded rau hauv channel steel duab thiab welded nrog steel phaj. Vim muaj kev siv ntau zaus, cov qauv ntawm tus ncej counterweight kuj txawv me ntsis. Raws li txoj kev sib txawv traction, tus ncej counterweight yuav muab faib ua ob hom: log counterweight thav duab rau 2: 1 sling txoj kev thiab wheelless counterweight thav duab rau 1: 1 sling txoj kev. Raws li qhov sib txawv counterweight guide rails, nws muaj peev xwm muab faib ua ob hom: counterweight racks rau T-shaped qhia rails thiab caij nplooj ntoos hlav zawv zawg phau ntawv qhia khau, thiab counterweight racks rau hollow qhia rails thiab steel zawv zawg qhia khau.
Thaum qhov ntsuas load ntawm of the elevator txawv, cov specifications ntawm seem steel thiab steel phaj siv nyob rau hauv lub counterweight ncej kuj txawv. Thaum siv cov kev qhia tshwj xeeb ntawm ntu steel raws li cov kab hluav taws xob ncaj ncaj, yuav tsum tau siv lub qhov hnyav hlau thaiv uas sib haum rau qhov loj ntawm cov ntu steel thais.
Lub luag haujlwm ntawm lub elevator counterweight yog kom sib npaug ntawm qhov hnyav ntawm lub tsheb los ntawm nws qhov hnyav kom txo tau lub zog ntawm lub tshuab traction thiab txhim kho kev ua haujlwm traction. Lub traction hlau hlua yog ib qho tseem ceeb ntawm kev ncua ntawm lub elevator. Nws dais tag nrho cov luj ntawm lub tsheb thiab lub counterweight, thiab tsav lub tsheb nce thiab nqis los ntawm kev sib txhuam ntawm traction sheave zawj. Thaum lub sijhawm ua haujlwm ntawm of the elevator, txoj hlua khi hlua khi yog khoov unidirectionally los yog hloov ib ncig ntawm lub traction sheave, coj sheave los yog anti-rope sheave, uas yuav ua rau tensile kev nyuaj siab. Yog li ntawd, txoj hlua traction hlau yuav tsum muaj lub zog siab thiab hnav tsis kam, thiab nws lub zog tensile, elongation, yooj, thiab lwm yam yuav tsum tau ua raws li cov kev cai ntawm GB8903. Thaum siv cov hlua hlau, nws yuav tsum tau kuaj xyuas tsis tu ncua raws li cov kev cai, thiab cov hlua hlau yuav tsum tau saib xyuas raws sijhawm.
1. Teem lub platform kev khiav hauj lwm ntawm qhov chaw sib thooj ntawm lub scaffold (kom yooj yim rau kev nqa ntawm lub txee lub cev thiab kev teeb tsa ntawm lub txee thaiv).
2. Khi ib txoj hlua hlua khi ntawm ob qhov kev tawm tsam kev sib tw ntawm cov kev taw qhia kev tsheb nqaj hlau ntawm qhov siab tsim nyog (kom pab txhawb nqa lub txee), thiab dai ib txoj hlua rau hauv nruab nrab ntawm cov hlua hlau buckle.
3. Ib qho 100mm X 100mm ntoo square tau txais kev txhawb nqa ntawm txhua sab ntawm qhov ntsuas qhov hnyav. Thaum txiav txim siab qhov siab ntawm cov ntoo square, qhov kev ncua deb ntawm lub elevator yuav tsum tau txiav txim siab.
4. Yog tias cov khau taw qhia yog hom caij nplooj ntoos hlav lossis hom ruaj khov, tshem tawm ob lub khau qhia ntawm tib sab. Yog tias cov khau qhia yog hom menyuam, tshem tag nrho plaub phau ntawv khau.
5. Thauj lub qhov hnyav hnyav rau ntawm qhov chaw ua haujlwm, thiab sib txuas cov hlua khi lub taub hau thiab cov hlua sib txuas ua ke nrog cov hlua hlua khi.
6. Ua haujlwm ntawm cov saw hlau rewinding thiab maj mam hoist lub counterweight thav duab mus rau qhov siab predetermined. Rau lub counterweight thav duab nrog lub caij nplooj ntoos hlav-hom los yog tsau phau ntawv qhia khau ntawm ib sab, txav lub counterweight thav duab kom cov phau ntawv qhia khau thiab sab qhia rails raws li zoo raws li. Khaws kev sib cuag, thiab maj mam loosen cov saw kom lub thav duab thav duab tsis tu ncua thiab khov kho rau ntawm lub rooj ntoo ua ntej txhawb nqa. Thaum lub counterweight thav duab tsis muaj kev taw qhia khau yog tsau rau ntawm cov ntoo square, ob sab ntawm lub thav duab yuav tsum tau ua raws li qhov kawg ntawm qhov kev taw qhia rail. Qhov kev ncua deb yog sib npaug.
7. Thaum txhim kho cov kev taw qhia ruaj khov, xyuas kom meej tias qhov sib txawv ntawm lub hauv ob sab hauv thiab qhov kawg ntawm cov kev taw qhia kev tsheb ciav hlau zoo ib yam nrog rau sab sauv thiab sab qis. Yog tias tsis tau raws li qhov yuav tsum tau ua, shims yuav tsum tau siv rau kev hloov kho.
8. Ua ntej yuav txhim kho lub caij nplooj ntoos hlav-loaded phau ntawv qhia khau, phau ntawv qhia khau kho cov txiv ntoo yuav tsum tau nruj rau qhov siab tshaj plaws kom tsis txhob muaj qhov sib txawv ntawm cov khau qhia thiab phau ntawv qhia khau thav duab, uas yooj yim rau nruab.
9. Yog hais tias qhov sib txawv ntawm sab sauv thiab sab hauv hauv ob sab phlu ntawm phau ntawv qhia khau slider yog tsis sib haum nrog cov khiav kawg nto, siv ib tug gasket ntawm tus taw qhia khau lub rooj zaum thiab lub counterweight thav duab los kho, txoj kev hloov yog tib yam li ntawm cov kev taw qhia ruaj khau.
10. Cov khau khiab rau cov menyuam yuav tsum tau muab ntsia kom zoo. Tom qab lub rollers ntawm ob sab nias rau ntawm txoj kev tsheb ciav hlau, tus nqi ntawm lub caij nplooj ntoos hlav compression ntawm ob lub rollers yuav tsum sib npaug. Cov menyuam pem hauv ntej yuav tsum tau nias kom nruj nrog txoj kab khiav, thiab qhov nruab nrab ntawm lub log yuav tsum tau ua raws li qhov nruab nrab ntawm txoj kev tsheb ciav hlau.
11. Kev teeb tsa thiab kho cov txee
①Siv lub platform nplai los ntsuas qhov hnyav ntawm ib qho los ntawm ib qho, thiab xam qhov hnyav nruab nrab ntawm txhua qhov thaiv.
② Thauj khoom tus lej sib npaug. Tus lej ntawm qhov hnyav yuav tsum raug xam raws li cov qauv hauv qab no:
Tus naj npawb ntawm counterweights ntsia = (lub tsheb hnyav + rated load × 0.5) / hnyav ntawm txhua qhov hnyav
③Nruam cov cuab yeej tiv thaiv kev vibration ntawm qhov hnyav raws li qhov xav tau.
