Cov Lus Qhia Rau Kev Yuav Choj Cranes hauv Cov Hluav Taws Xob

Apr 17, 2023

Cov lus qhia rau kev yuav cov choj cranes hauv cov chaw tsim hluav taws xob
 

1 Cov kev xav tau ntawm kev ua haujlwm
 

1.1 Kev tsim thiab tsim khoom ntawm crane yuav tsum ua kom tau raws li cov cai thiab cov qauv tsim nyog. Cov cuab yeej txhawb nqa ntawm lub crane yuav tsum tsis txhob yog cov cuab yeej txwv lossis tshem tawm los ntawm lub xeev.
 

1.2 Lub laub, trolleys thiab lifting mechanisms yuav tsum muaj kev txhim khu kev qha braking systems, end-stroke limit devices and buffer devices. Lub tshuab hoisting muaj ob qho kev tiv thaiv kev tiv thaiv, thiab lub crane txais cov polyurethane buffers.
 

1.3 Txhua qhov kev sib hloov yuav tsum muaj lub tshuab lubrication txhim khu kev qha.
 

1.4 txwv qhov yuav tsum tau rau kev tsav tsheb nuv
 

2 Vuam yuav tsum
 

Daim ntawv vuam thiab qhov loj me yuav tsum ua raws li cov kev cai ntawm GB324-88 "Vuam Specifications" thiab GB986-88 "Daim foos thiab Qhov Loj ntawm Kev Taw Qhia Arc Welding Joints".

3 Cov ntaub ntawv xav tau
 

Tsim nyog xaiv cov khoom siv rau tus choj, trolley, nuv thiab accessories, thiab tus choj qauv siv Q235 kom ua tau raws li kev ua haujlwm nyob rau hauv ntau yam kev mob. Yam tsawg kawg yuav tsum tau ua raws li cov qauv hauv qab no: (yog tias muaj cov qauv tshiab, siv tus qauv tshiab).
 

a. GB 699-88 "Technical Conditions for High Quality Carbon Structural Steel"
 

b. GB 700-88 "Carbon Structural Steel"
 

c. GB1102-74 "Round Strand Hlau hlua"
 

d. GB1348-88 "Low Alloy Steel Qauv"
 

e. GB 11352-89 "Carbon Steel Castings for General Engineering"
 

f. GB 9439-88 "Grey Iron Castings"

4 Cov khoom siv hluav taws xob xav tau
 

4.1 Cov khoom siv hluav taws xob muaj xws li lub cev muaj zog thiab lawv cov khoom siv tswj, thiab kev pib ua haujlwm yuav tsum ua raws li cov khoom siv tshuab.
 

4.2 Cov khoom siv hluav taws xob suav nrog cov neeg tsim hluav taws xob tsim nyog, nres, tswj, thiab lwm yam, nrog rau qee qhov tsim nyog cov hluav taws xob hloov hluav taws xob, cov hluav taws xob tiv thaiv, overcurrent relays lossis fuses. hais lus. Kev ncua cable conductivity hom rau trolley conductivity.
 

4.3 Lub zog hloov pauv ntawm lub cev muaj zog suav nrog cov cuab yeej tswj hwm yog 80 feem pua ​​-110 feem pua, thiab nws tau lees paub pib ntawm 80-100 feem pua ​​​​ntawm cov ntsuas hluav taws xob thiab ntsuas zaus. Qhov ntsuas torque ntawm lub cev muaj zog yuav tsum ua raws li cov qauv ntawm cov khoom siv hluav taws xob hauv lub tebchaws, cov chav kawm rwb thaiv tsev yuav tsum yog F chav kawm (qhov kub thiab txias yuav tsum raug ntsuas los ntawm chav kawm B), thiab chav tiv thaiv yuav tsum yog IP44. Lub cev muaj zog yog 380V.
 

4.4 Lub cev muaj zog muaj peev xwm txaus los nqa lub nra ntawm lub hoist. Nyob rau hauv cov xwm txheej ntawm qhov siab tshaj plaws ntxiv rau 43.4 degree / heev yam tsawg kawg nkaus -20 degree thiab qhov siab ntawm 111.5m, lub tshuab hoisting tuaj yeem ua haujlwm tsis tu ncua rau 60 feeb yam tsis muaj qhov txawv txav. Cov motors yuav tsum siv cov kabmob tiv thaiv kev sib txhuam thaum twg los tau.
 

4.5 Txhua lub tshuab nqa nqa yuav tsum tau nruab nrog qhov hloov pauv tsis siv neeg hloov pauv.
 

4.6 Lub overload limiter (nqus) ntawm lub cuab yeej yog nruab nrog lub tswb tsis siv neeg. Cranes yuav tsum tau nruab nrog tswb tswb.
 

4.7 Ntu ntawm tag nrho cov xov hlau thiab cables yuav tsum tsis pub tsawg dua 1.5mm2 tooj liab tub ntxhais, thiab tag nrho cov cables thiab xov hlau yuav tsum yog hom marine.
 

4.8 Muaj 4 lub teeb tiv thaiv kev vibration nyob rau hauv tus choj tsav tsheb.

5 Kev tswj hwm thiab kev tiv thaiv yuav tsum tau ua
 

5.1 Cranes yuav tsum tau nruab nrog kev qhia, saib xyuas thiab tiv thaiv cov cuab yeej.
 

5.2 Cov cuab yeej tswj hluav taws xob yuav tsum suav nrog cov hauv qab no (tsis txwv rau):
 

Crane tiv thaiv lub thawv, resistor, kev khiav hauj lwm mechanism tswj vaj huam sib luag, hoisting mechanism tswj vaj huam sib luag.
 

5.3 Lub crane yuav tsum muaj kev tiv thaiv hauv qab no:
 

Kev tiv thaiv luv luv, kev tiv thaiv hauv av, kev tiv thaiv dhau tam sim no, kev tiv thaiv hluav taws xob tsis zoo, kev tiv thaiv xoom hla, nce txwv kev tiv thaiv, tiv thaiv kab mob stroke, tiv thaiv hluav taws xob thaum muaj xwm ceev.
