Choj Log

Choj lub log yog cov khoom siv tseem ceeb uas pab txhawb txoj kev du ntawm lub crane raws cov railwing rails. Lawv ris tag nrho cov kev thauj khoom ntawm lub crane thiab cov ntaub ntawv nqa, ua haujlwm ruaj khov thiab ua haujlwm ruaj khov.

1. Muaj nuj nqi ntawm Choj Crane log
Kev them nyiaj yug & txav: lub log txhawb nqa lub cev hnyav (suav nrog cov hoist thiab ntim kab rov tav raws cov teeb pas dej.

Thauj khoom: Lawv faib cov Crane lub thauj khoom kom tiv thaiv kom tsis txhob muaj kev ntxhov siab ntau dhau ntawm kev tsheb nqaj hlau lossis lub log.

Kev taw qhia: Cov log muaj kev tswj hwm ua kom nruj nrog cov ntsia kom tiv thaiv kev ua haujlwm derailment thiab ua kom pom tseeb.

2. Hom ntawm choj crane log
A. Raws li cov khoom siv
Forged Steel Log:

Lub zog siab thiab lub siab ntev rau cov ntawv thov hnyav.

Tiv taus hnav thiab deformation.

Nrum Hlau Log:

Kev lag luam tab sis tsawg dua li cov hlau; siv rau kev nrawm dua.

Nquag mus tawg ua kom hnyav.

Nylon \/ Polyurethane Log:

Siv nyob rau hauv cov chaw tshwj xeeb (xws li, cov suab nrov-rhiab lossis cov mob corrosive).

Qis dua thauj khoom tab sis quieter kev ua haujlwm.

B. Raws li Flange Design
Ob Chav Flange Flange:

Flanges ntawm ob sab los tiv thaiv kev txav sab tom qab (ib txwm muaj rau cov tsiaj loj).

Tib Chav Flange:

Ib tus flange rau kev taw qhia, siv nyob rau hauv cov kab ke nrog kev txhawb nqa rail rollaints ntxiv.

Cov log flangeless:

Siv nrog cov phau ntawv qhia sab nraud lossis cov tshuab uas ntsia cov ciav hlau muaj kev sib ncag.

C. Raws li kev thauj khoom muaj peev xwm
Cov tub ntxhais lub luag haujlwm log: rau lub teeb mus rau kev thauj khoom.

Cov Hnyav-Luag Log: Tsim kom muaj peev xwm muaj peev xwm cranes (piv txwv li, cov hlau loj, chaw nres nkoj).

3. Cov kev txiav txim siab tseem ceeb
Log txoj kab uas hla: diamerers loj dua cov hnav thiab txhim kho load faib.

Hardness: log feem ntau yog kho cua sov (piv txwv li, hrc 55-60}) kom tiv thaiv kev hnav.

TENT PROFILE: Tiaj li lossis me ntsis convex kom phim cov hlau txuas thiab txo kev sib cuag kev ntxhov siab.

Hom Hom: Qhov tseem ceeb, Tapered Bore, lossis Plain Bore rau mounting ntawm lub qag.

4. Cov qauv tsis ua tiav
Hnav: Vim yog kev sib txhuam lossis cov khib nyiab abbrasive.

Pitting: Nto qaug zog los ntawm kev thauj mus los.

Nrib pleb: tshwm sim los ntawm overloading lossis khoom tsis xws luag.

Flange kev puas tsuaj: misalignment lossis cov teeb meem tsheb ciav hlau tuaj yeem tawm ntawm cov flanges.

 

Khoom siv:

Choj crane log yog feem ntau ua los ntawm high-zog, hnav-resistant cov ntaub ntawv los tuav cov khoom hnyav thiab nquag siv. Cov Khoom Siv Uas Muaj:

Daim duab kos

 

 

Choj lub log yog cov khoom tseem ceeb uas ua kom muaj peev xwm du, thiab load-coj muaj peev xwm muaj peev xwm. Ntawm no yog cov ntsiab lus zoo ntawm cov log zoo crane:

1. Siab load-yam muaj peev xwm muaj peev xwm
Tsim los daws cov nra hnyav yam tsis muaj deformation.

Ua los ntawm cov khoom siv ruaj (forged steel, cam khwb cia hlau, lossis polyurethane) los txhawb crane hnyav thiab them nyiaj.

2. Kev dai & ua kom zoo
Precision-machined rau txawm dov, txo nws hwj chim lossis tshee.

Ua kom ntseeg tau yog qhov chaw muaj tseeb, tseem ceeb heev hauv kev tsim khoom thiab chaw tsim khoom.

3. Txo kev sib nrauj & hnav
Hardened Tread thaj chaw tsawg kawg nkaus hnav los ntawm kev sib tw ciav hlau tas li.

Lubricated los yog ntim cov ris tsho txo ​​cov yob tiv thaiv, nthuav kev ua neej.

4. Cov kev saib xyuas tsawg
Kev tsim kho ruaj khov txo cov hloov pauv nquag.

Kaw cov kabmob tiv thaiv cov plua plav thiab cov khib nyiab hauv cov khoom siv, cov kev xav tau kev saib xyuas qis dua.

5. Cov suab nrov txo
Polyurethane lossis cov log nylon muaj log muaj ntau dua li hlau log, zoo tagnrho rau cov chaw sab hauv tsev.

6. Corrosion & Thaum Tshav Kub Kub Kuj
Stainless hlau lossis coated log tiv xeb tiv thaiv taus hauv noo

 

 

Choj lub log yog cov khoom siv tseem ceeb uas pab txhawb txoj kev du ntawm lub crane raws cov railwing rails. Lawv tsim los txhawm rau ntaus hnyav thauj khoom thaum ua kom ruaj khov, ua kom meej, thiab kav ntev. Ntawm no yog ib qho ntsiab lus qhia txog lawv daim ntawv thov, hom, thiab kev txiav txim siab tseem ceeb:

Cov ntawv thov ntawm choj Crane log
Nyiaj Siv Ua Haujlwm Cranes (EOT Cranes)

Siv rau hauv kev tsim cov nroj tsuag, chaw khaws khoom, thiab cob qhia rau kev nqa thiab thauj cov khoom siv hnyav.

Feem ntau pom nyob rau hauv cov millic, kev lag luam lag luam, thiab cov chaw tsim khoom.

Gantry Cranes

Ua haujlwm hauv cov nkoj nkoj, ntim cov thawv, thiab sab nraum zoov cia vaj khoom tsev uas cov crane txav ntawm cov ciav hlau hauv av.

Jib Cranes

Siv nyob rau hauv cov chaw ua haujlwm me (piv txwv li, sib dhos cov kab) qhov twg yuav tsum tau txav chaw.

Monorilator Systems

Siv nyob rau hauv cov khoom siv cov tshuab tuav qhov twg loads txav mus raws txoj kev ruaj (piv txwv li cov kab ntau lawm).

 

 

Cov txheej txheem ntau lawm rau choj log crane log muaj ntau cov kauj ruam tseem ceeb kom paub meej, thauj khoom muaj peev xwm, thiab ua haujlwm du. Hauv qab no yog cov ntsiab lus ntxaws ntxaws ntawm kev tsim khoom:

1. Cov khoom xaiv
Thawj cov khoom siv: feem ntau forged lossis cam, 42crmo, 65mn, lossis 55 steel) rau siab zog thiab hnav tsis kam.

Kev Kho Cua Sov: Alloy steel log yauv mus sab nrauv thiab npau taws kom ua tiav hardness (feem ntau hrc 45-55) thiab tawv.

2. Kev Tsim Kho Cov Txheej Txheem
A. Forging lossis Casting
Forging (nyiam rau cov khoom siv hnyav):

Billet steel yog rhuab thiab nias mus rau hauv cov log tsis muaj qhov sib tw rau cov qauv lis loj dua.

Zoo dua cov yam ntxwv dua li casting.

Casting (nqi-tsim nyog rau cov qis loads):

Molten Steel tau nchuav rau hauv cov pwm (xuab zeb casting lossis precision casting).

Yuav tsum muaj post-casting machining rau precision.

B. Rughing Machining
Tig lub forged \/ nrum dawb paug rau kev kwv yees qhov ntev.

Cov txheej txheem:

Tshuab dhos txoj siav rau sab nraud txoj kab uas hla (OD), sab hauv lub taub (ID), thiab tsuj taw profile.

Drilling \/ Boring rau qag bore.

C. Kev Kho Tshav Kub Kub
Quenching & Tempering: Txhim kho lub hardness thiab hnav tsis kam.

Induction hardening: xaiv tau rau tread saum npoo kom ntev lifespan.

D. Precision Machining
CNC TSHUAB DHOS \/ MILLING: POLDECTES TIV THAIV (nws 7-}).

Kev sib tsoo: kom ntseeg tau du chaw saum npoo (RA tsawg dua lossis sib npaug rau 1.6 μm).

Qhov tseem ceeb \/ Groove Machining: Rau lub log flanges (yog tias yuav tsum tau).

E. Flange & Tread Profiling
Flanges yog machined los tiv thaiv kev ua haujlwm derailment.

TENE PROFILE yuav tiaj tus, conical, los yog crowned rau kev vam meej.

Kev kuaj Hardness: Rockwell lossis Brinell testers.

NDT (tsis yog-kev sim ua txhaum):

Kev sim ultrasonic (U) rau sab hauv kev tsis zoo.

Sib nqus particate (MPI) rau cov nyom.

Dynamic sib npaug ntsuas: ua kom cov kev sib hloov du ntawm kev kub ceev.

4. Nto Kho
Txhaj tshuaj blasting: ntxuav thiab txhim kho kev nkees tsis kam.

Painting \/ Galvanizing: Los tiv thaiv corrosion (piv txwv li, zinc plating rau cov chaw hnyav).

5. Los Ua Ke & Kuaj
Xovxwm-haum rau ntawm Axles: Log yog mounted nrog bearings (piv txwv li, cov menyuam tawv nqaij).

Kev ntsuas ntsuas: simulated crane ua haujlwm nyob rau hauv max load (piv txwv li, 1.25x muaj peev xwm muaj peev xwm).

Kev kuaj khiav: Cov tshev rau suab nrov, kev co, thiab kev sib ncag.

6. Ntim & Xa Khoom
Ntoo crates lossis steel pallets rau kev tiv thaiv.

Khij nrog cov lus qhia tshwj xeeb (cov khoom siv, kev ntaus nqi, tawv).

 

 

Lub tuam txhab tau teeb tsa cov khoom siv tswj hwm kev txawj ntse platform, thiab tau teeb tsa 310 teev (teeb tsa) ntawm kev tuav thiab vuam hlau. Tom qab ua tiav ntawm txoj kev npaj, yuav muaj ntau tshaj 500 teev (teeb tsa), thiab cov khoom siv sib txuas lus yuav ncav cuag 95%. 32 siv cov kab sib tw tau muab tso rau hauv kev siv, 50 tau npaj yuav tsum tau nruab, thiab kev siv lub tshuab ntawm cov kab kev tau txais tag nrho.
