Lifting Crane Cov Lus Qhia Rau U

Raws li lub npe qhia, nqa crane feem ntau yog siv los nqa cov khoom hnyav hauv ntau qhov chaw. Tus choj crane yog peb cov khoom tseem ceeb. Cov lus qhia siv thiab kev paub txog tus choj crane yog rau koj siv. Yog tias koj muaj lus nug, thov koj xav tiv tauj peb!

Choj cranesyog cov cuab yeej siv tshuab uas tau teeb tsa saum toj ntawm kev cob qhia, warehouses, thiab qhib chaw cia khoom nqa ntau yam khoom. Lawv feem ntau hu ua "overhead cranes" lossis "traveling cranes". Lawv yog ib qho ntawm feem ntau siv hom lifting machinery nyob rau hauv mechanical, metallurgical, thiab tshuaj industries. Nyob rau hauv niaj hnub kev lag luam kev lag luam, lawv yog cov cuab yeej tseem ceeb rau kev ua tiav tshuab thiab automation ntawm cov txheej txheem ntau lawm, txo cov zog lub cev hnyav, thiab txhim kho kev tsim khoom. Thaum siv choj cranes, yuav tsum tau ceev faj txog kev nyab xeeb hauv qab no:

1. Lub crane yuav tsum nyob rau hauv ib txwm muaj, tshwj xeeb tshaj yog cov khoom siv kev nyab xeeb xws li lub tshuab braking, lub suab thiab lub teeb pom kev, cov khoom siv sib cuam tshuam, thiab lwm yam, yuav tsum muaj kev nkag siab thiab zoo.

2. Thaum lub sijhawm ua haujlwm, tus neeg teb xov tooj yuav tsum tau ua kom muaj zog. Ua ntej lifting, ua qhov khoob ua ntej, ces nqa lub load. Thaum lub lifted khoom yog 100 mus rau 150 mm tawm hauv av, yog tias nws pom tias cov khoom tsis ruaj ntseg khi, nws yuav tsum tau re- khi. Ua ntej pib lub crane, lub tswb nrov yuav tsum tau suab. Cov khoom nqa yuav tsum tsis txhob hla tib neeg lub taub hau. Thaum lub crane nyob hauv kev txav, nws yog nruj me ntsis txwv tsis pub kho, tshuaj xyuas, roj lossis so cov tshuab. Yog tias pom muaj teeb meem thaum lub sijhawm ua haujlwm, lub crane yuav tsum tau nres tam sim ntawd.

3. Thaum kawg ntawm kev ua haujlwm, lub crane yuav tsum tau nres ntawm txoj kab nres tsheb, tus nuv yuav tsum tau tsa rau saum, thiab tsis muaj cov khoom hnyav yuav tsum tau dai ntawm tus nuv. Tag nrho cov tswj thiab levers yuav tsum tau teem rau xoom txoj hauj lwm, thiab lub hwj chim hloov yuav tsum tau muab tua thiab lub cab qhov rooj xauv.

4. Choj cranes yuav tsum tau nruab nrog cov khoom siv txhim khu kev qha thiab muaj kev nyab xeeb. Feem ntau, lawv tau nruab nrog buffers, limiters (mus ncig tebchaws limiters, lifting limiters), lifting limiters, thiab anti- cua rail clamps, thiab lwm yam.

5. Cov txheej txheej ntawm txhua qhov hluav taws xob ntawm lub crane yuav tsum muaj kev ntseeg siab hauv av kom tsis txhob muaj hluav taws xob poob rau tus neeg teb xov tooj. Thaum lub trolley khiav tsis welded rau lub ntsiab nqaj, nws yuav tsum tau welded thiab grounded. Lub transformer yuav tsum tau grounded nyob rau hauv qis -voltage sab raws li xav tau.

6. Choj cranes yuav tsum tsis txhob nqa raws li cov xwm txheej hauv qab no:

a. Tsis muaj leej twg hais kom ua, lossis lub teeb liab hais kom tsis raug.

b. Cov khoom siv crane muaj qhov tsis xws luag, lossis cov khoom siv kev nyab xeeb tsis ua haujlwm.

c. Kev nqa dhau lub peev xwm lossis qhov hnyav ntawm cov cuab yeej tsis paub.

d. Cov neeg sawv ntawm qhov khoom nqa los yog raug nqa los ntawm crane nuv.

e. Lub teeb tsaus, thiab qhov pom tsis meej.

f. Cov khoom nqa tau muaj cov npoo ntse lossis cov fab, lossis yog nqa ntawm lub kaum sab xis yam tsis tau ntsuas kev nyab xeeb.

Raws li ib feem tseem ceeb ntawm kev saib xyuas tag nrho thiab kev saib xyuas ntawm choj cranes, kev saib xyuas cov cuab yeej siv tshuab yog ib qho tseem ceeb heev. Nws feem ntau suav nrog xya yam hauv qab no:

1. Tsis tu ncua xyuas cov brakes ntawm tus choj crane thiab kho lub log nres kom raws sijhawm kom ntseeg tau tias qhov kev hloov pauv thiab kev ntseeg siab ntawm cov nres thiab lub log nres. Qhov sib txawv yuav tsum tau khaws cia ntawm 0.5 thiab 1.0 millimeters. Nws yog ib qho tsim nyog los xyuas kom meej tias tsis muaj av ntawm qhov sib txhuam. Yog tias pom muaj, nws yuav tsum tau ntxuav nrog nyias nyias lossis roj av.

2. Hais txog lub lubrication ntawm tus choj crane, xyuam xim rau lub lubrication ntawm lub reducer, gearbox, thiab lwm yam meshing iav thiab lwm yam. Nyob rau tib lub sij hawm, cov roj hydraulic yuav tsum tau lubricated raws li qhov yuav tsum tau ntawm lub rooj lubrication.

3. Tshawb xyuas cov hlautxoj hluantawm tus choj crane ua raws li cov kev cai cuam tshuam. Yog tias nws dhau qhov kev cai, nws yuav tsum tau hloov kho tam sim ntawd.

4. Tsis tu ncua xyuas qhov huv ntawm txoj kev khiav thiab xyuas kom meej tias tsis muaj av, xuab zeb, lossis pob zeb hauv lub zog.

5. Ua tib zoo saib xyuas qhov nruj ntawm kev sib txuas bolts ntawm tus choj crane lub cev thaum nws nyob hauv siab. Tsis tas li, nquag xyuas seb qhov kev sib txuas ntawm ntau yam khoom puas ruaj khov. Yog tias pom muaj qhov xoob xoob, nws yuav tsum tau nruj kom sai.

6. Nco ntsoov xyuas seb puas muaj suab nrov thaum lub sijhawm ua haujlwm ntawm lub tshuab. Yog tias kev ua haujlwm tsis zoo, nws yuav tsum tau kho tam sim ntawd.

7. Ua tib zoo saib xyuas kev ua haujlwm ib txwm ua ntawm lub tshuab tig. Thaum kuaj xyuas, xyuas kom meej tias cov kab nruab nrab ntawm tus choj crane mechanism yog sib npaug rau cov kab nruab nrab ntawm cov iav. Tsis tas li ntawd, qhov sib txawv hauv nruab nrab yuav tsum tsim nyog.
