Lub crawler taug qab khau tsim lub hauv paus ntawm kev txav ntawm koj lub crawler crane. Cov khau txhawb nqa tag nrho qhov hnyav ntawm lub crane, tsim traction ntawm txawv struts, thiab pab cushion muaj kev cuam tshuam rau saum npoo thaum hoisting loads. Ib qho kev hnav ntxov ntxov ntawm nkawm khau nce nqi kho.
1. Ua kev soj ntsuam tsis tu ncua
Kev tshuaj xyuas tsis tu ncua yog ib txoj hauv kev zoo tshaj plaws los ntes cov teeb meem ua ntej lawv loj.
Dab tsi los kuaj ua ntej thiab tom qab txhua qhov haujlwm:
Kev tawg los yog pom kev puas tsuaj ntawm cov khau khiav
Kev hnav ntau dhau ntawm grouser (wedge) qhov siab
Loose, ploj lawm, los yog puas mounting bolts
Deformation los yog misalignment
Cov khoom txawv teb chaws nyob nruab nrab ntawm cov khoom siv khiav
Kev soj ntsuam tag nrho - qhov ntev yuav tsum tau ua ib ntus uas siv cov calipers thiab torque wrenches. Rau cov khoom tseem ceeb, taug qab phaj thickness yuav tsum tau ntsuas ntawm ntau lub ntsiab lus. Raws li txoj cai dav dav, yuav tsum tau hloov pauv thaum thickness poob qis dua qhov chaw tsim khoom txwv (feem ntau nyob ib ncig ntawm 25mm) lossis thaum hnav tshaj 50% ntawm qhov qub.
2. Khaws cov khau kom huv si
Av nkos, av nkos, gravel, thiab khib nyiab yog cov yeeb ncuab tseem ceeb ntawm kev taug kev khau mus ntev. Cov ntaub ntawv abrasive ua zoo li cov ntawv xuab zeb ntawm cov khoom txav, ua kom nrawm nrawm ntawm cov khau, pins, thiab bushings.
Kev ua kom huv:
Tshem tawm cov av thiab cov khib nyiab pov tseg tom qab txhua qhov ua haujlwm
Ua tib zoo saib xyuas tshwj xeeb rau qhov nyuaj-mus rau- mus txog thaj chaw nyob ib puag ncig tus pins thiab bolts
Siv dej, txhuam hniav, lossis cua compressed - zam cov cuab yeej ua phem uas tuaj yeem ua rau lub ntsej muag puas
3. Lubricate txav Cheebtsam
Kev lubrication kom zoo txo kev sib txhuam ntawm cov khau khiav, pins, thiab bushings, txo cov hlau - mus rau -hlau sib cuag thiab cua sov.
Cov ntsiab lus tseem ceeb ntawm lubrication:
Taug qab khau pin shafts
Bushings
Bolts thiab fasteners
4. Zam kev ua haujlwm yuam kev
Tus neeg ua haujlwm tus cwj pwm cuam tshuam ncaj qha mus taug qab khau lub neej. Qee qhov kev coj ua nrawm nrawm thiab ua rau muaj kev pheej hmoo ntawm kev tawg:
| Xyaum kom zam | Yog vim li cas Nws puas Taug Kev khau |
|---|---|
| Siab - nrawm lossis ntse tig | Lub zog tsis sib xws ua rau nrawm nrawm thiab muaj peev xwm tawg |
| Kev thauj khoom ntau dhau | Kev ntxhov siab ntau dhau ua rau muaj kev pheej hmoo tawg thiab ua rau lub neej ua haujlwm luv |
| Ntev -kev mus deb | Kev ua haujlwm tas mus li yam tsis tau so ua kom qaug zog hnav |
| Tsav los ntawm cov pob zeb ntab | Chassis tilting tuaj yeem ua rau cov khau taug kev puas lossis tawg |
| Lub sij hawm ntev unbalanced loading | Ib sab hnav tawm ntxov ntxov, yuav tsum tau hloov tsis sib xws |
Kev ua haujlwm du nrog txawm tias kev faib tawm kev ntxhov siab yog qhov tseem ceeb los txo cov kev puas tsuaj.
5. Tswj kom muaj kev sib tw zoo
Taug qab nro uas xoob dhau los yog nruj dhau ua rau muaj teeb meem:
| Qhov teeb meem | Qhov tshwm sim |
|---|---|
| xoob dhau lawm | Taug qab slippage, teeb meem stability, ceev hnav |
| nruj dhau lawm | Kev ntxhov siab ntau dhau ntawm cov pins, bushings, thiab bolts; nce tsav system load |
Tsis tu ncua saib xyuas thiab kho qhov nro ntawm cov chaw tsim khoom tshwj xeeb. Rau 200-tuj chav kawm crane, tus nqi nro yog li ntawm 80 txog 120 kN.
6. Torque Mounting Bolts kom raug
Cov khau khiab khau khiab xoob ua rau muaj kev vibrations, hnav tsis sib xws, thiab muaj peev xwm tiv thaiv tsis ua haujlwm.
Siv lub torque ciaj ntswj kom nruj bolts rau cov chaw tsim khoom -cov nqi tshwj xeeb
Rau ib tug raug crawler crane, ntsia liaj qhov rooj torque yuav nyob ib ncig ntawm 560 lb-ft (760 Nm)
Txheeb xyuas qhov nruj nruj tsis tu ncua-qee qhov chaw pom zoo txhua 250 txog 500 teev ua haujlwm
7. Hloov cov khau khiab khau raws sijhawm
Taug qab khau hnav ntawm tus nqi sib txawv nyob ntawm kev siv thiab ib puag ncig. Kev hloov pauv qeeb thaum hnav ntau tshaj qhov txwv tuaj yeem ua rau lwm yam khoom hauv qab, suav nrog cov hlua, cov menyuam, thiab sprockets.
Thaum twg los hloov:
Grouser qhov siab hnav tshaj qhov chaw tsim khoom specifications
Peb lossis ntau dua cov khau tawg ntawm ib leeg
Bolt hloov tus nqi siab tshaj 30% ib ntu
Ntug curling deformation ntau dua 5 hli
Kev nyuaj siab tob rau ntawm qhov chaw sib cuag
8. Xav txog kev hloov txoj hauj lwm ib ntus
Txhawm rau txhawb nqa txawm tias hnav hla txhua txoj kev taug kev khau, xav txog kev sib hloov cov khau txoj haujlwm ib ntus. Qee tus neeg ua haujlwm pom zoo kom tig khau txhua txhua 250-500 teev ua haujlwm. Qhov kev coj ua no faib cov khaub ncaws ntau sib npaug thoob plaws lub teeb thiab txuas ntxiv lub neej kev pabcuam tag nrho.
