Dab tsi yog qhov sib txawv ntawm crane rail?
Crane rails yog cov tshwj xeeb steel lem tsim los tiv thaiv cov huab cua compressive stresses thiab lateral rog generated los ntawm hnyav lifting khoom. Vim tias muaj cov ntawv thov kev lag luam los ntawm lub Hoobkas me me nyiaj siv ua haujlwm hoists mus rau qhov chaw nres nkoj loj heev gantry cranes, tsis muaj "ib- loj- haum-tag nrho" crane rail. Hloov chaw, ntau hom crane rails raug cais raws li lawv tus ntoo khaub lig-sectional profiles, hnyav ib meter, thiab cov qauv hauv cheeb tsam engineering lawv ua raws.
Raws li ib tug thawj coj ncaj qha chaw tsim tshuaj paus ntawm railway thiab crane khiav systems,GNEE RAILsiv lub xeev - ntawm - lub - kos duab dov mills thiab cov chaw kho cua sov siab heev los tsim cov khoom siv dav dav ntawm crane rails.
Main Hom Crane Rail
European Standard DIN 536 "A" Series
European DIN 536 tus qauv yog qhov sib txawv tshaj plaws uas tau lees paub crane rail specification thoob ntiaj teb. Rails nyob rau hauv pawg no raug xaiv los ntawm tsab ntawv "A" ua raws li tus lej uas kwv yees li nruab nrab ntawm qhov dav ntawm lub taub hau tsheb ciav hlau hauv millimeters (xws li A45, A55, A65, A75, A100, A120, A150).
| DIN536 Crane Rail | Lub taub hau dav (mm) |
Lub hauv paus dav | Rail Qhov siab | Lub duav Thickness | Nominal Nyhav (kg / m) |
|---|---|---|---|---|---|
| A45 | 45 (±0.6) | 125 (+1.5, -3) | 55 (±1) | 24 | 22.10 |
| A55 | 55 (±0.6) | 150 (+1.5, -3) | 65 (±1) | 31 | 31.80 |
| A65 | 65 (±0.8) | 175 (+1.5, -4) | 75 (±1) | 38 | 43.10 |
| A75 | 75 (±0.8) | 200 (+2, -5) | 85 (±1) | 45 | 56.20 |
| A100 | 100 (±1) | 200 (+2, -5) | 95 (±1.5) | 60 | 74.30 |
| A120 | 120 (±1) | 220 (+2, -5) | 105 (±1.5) | 72 | 100.00 |
| A150 | 150 (±1) | 220 (+2, -5) | 150 (±1.5) | 80 | 150.30 |
Lub ntsiab lus ntawm "A" series yog nws qhov profile qis, tshwj xeeb tshaj yog dav hauv paus, thiab lub vev xaib tuab. Qhov no squat, geometry ruaj khov muab qhov nruab nrab ntawm lub ntiajteb txawj nqus thiab cov hneev taw loj, tso cai rau kev faib tawm ntawm cov khoom hnyav ntsug mus rau hauv lub hauv paus pob zeb lossis steel girders. Cov kev tsheb ciav hlau no yog cov qauv kev xaiv rau hnyav-cov haujlwm overhead cranes, automated storage and retrieval systems (ASRS), thiab cov chaw lag luam loj.
Suav Standard YB/T 5055 "QU" Series
Dominating lub lag luam Esxias thiab nce siv nyob rau hauv thoob ntiaj teb infrastructure tej yaam num, Suav YB / T 5055 tus qauv nta "QU" series. Cov ntawv luv "QU" muab los ntawm Suav lub suab sau rau crane (Qi Zhong). Cov koob muaj xws li cov profiles xws li QU70, QU80, QU100, thiab QU120, nrog rau tus lej qhia qhov dav ntawm lub taub hau tsheb ciav hlau.
| QU Crane Rails | Lub taub hau dav A ± 1 (mm) |
Hauv qab dav B (mm) |
Rail Qhov siab H ± 0.8 hli |
Lub duav Thickness ± 1 (mm) |
Nominal Nyhav (kg / m) |
Siv Load (ton) |
|---|---|---|---|---|---|---|
| qw 70 | 70 | 120 | 120 | 28 | 52.77 | 32 |
| qw 80 | 80 | 130 | 130 | 32 | 64.41 | 50~75 |
| QU 100 | 100 | 150 | 150 | 38 | 89.05 | 100~125 |
| qw 120 | 120 | 170 | 170 | 44 | 118.50 | 160 |
Zoo ib yam li lub tswv yim rau DIN tus qauv, QU rails yog lub taub hau dav kom txo tau lub log kev nyuaj siab thiab lub web tuab kom tiv thaiv buckling nyob rau hauv siab - muaj peev xwm loads. Lawv tau tsim tshwj xeeb rau kev hnyav- lub luag haujlwm gantry cranes, chaw nres nkoj terminals, thiab shipyards uas txuas mus ntxiv, siab - kev ua haujlwm cuam tshuam yog cov qauv.
North American ASCE thiab AREMA Standards
Hauv North America, cov crane khiav nquag siv cov qauv tsim los ntawm American Society of Civil Engineers (ASCE) thiab American Railway Engineering thiab Maintenance- ntawm -Txoj Kev Koom Tes (AREMA). Rau cov khoom siv hluav taws xob sib dua, ASCE tee rails zoo li ASCE 60 lossis ASCE 85 feem ntau siv. Rau cov ntawv thov kev lag luam hnyav dua, hnyav -cov haujlwm railway profiles xws li 115 RE, 132 RE, lossis 136 RE feem ntau tau hloov kho rau kev siv crane.
| ASCE Rail | Lub taub hau dav (mm) |
Lub hauv paus dav | Rail Qhov siab | Lub duav Thickness | Nominal Nyhav (kg / m) | Khoom siv |
|---|---|---|---|---|---|---|
| ASCE12 (12-lb./yd rail) | 25.4 | 50.8 | 50.8 | 6.35 | 5.95 (12 lbs/yd) | 700 |
| ASCE20 (20-lb./yd rail) | 34.1 | 66.7 | 66.7 | 6.4 | 9.92 | 700 |
| ASCE25 (25-lb./yd rail) | 38.1 | 69.85 | 69.85 | 7.54 | 12.2 | 700 |
| ASCE30 (30-lb./yd rail) | 42.86 | 79.37 | 79.37 | 8.33 | 15.2 | 700 |
| ASCE40 (40-lb./yd rail) | 47.62 | 88.9 | 88.9 | 9.90 | 19.84 | 700 |
| ASCE 50 (50-lb./yd rail) | 54 | 98.43 | 98.43 | 11.11 | 24.85 | 700 |
| ASCE 60 (60-lb./yd rail) | 60.32 | 107.95 | 107.95 | 12.3 | 30.1 | 700 |
| ASCE70 (70-lb./yd rail) | 61.91 | 117.48 | 117.48 | 13.1 | 34.5 | 700 |
| ASCE75 (70-lb./yd rail) | 62.71 | 122.2 | 122.2 | 13.5 | 37.2 | 900A/1100 |
| ASCE 80 (80-lb./yd rail) | 63.50 | 127.00 | 127.00 | 13.89 | 39.82 | 900A/1100 |
| ASCE 85 (85-lb./yd rail) | 65.09 | 131.76 | 131.76 | 14.29 | 42.3 | 900A/1100 |
Tsis zoo li lub tiaj thiab squat DIN lossis QU rails, ASCE thiab AREMA rails muaj qhov siab dua "T-section" profile. Thaum xub thawj tsim los rau cov tsheb thauj mus los, lawv lub zog tensile siab thiab muaj ntau yam ua rau lawv yog ib qho tseem ceeb rau cov tshuab hnyav khiav hauv Asmeskas.
Japanese JIS Standard "CR" Series
Lub Japanese Industrial Standards (JIS) qhia lawv tus kheej tshwj xeeb profiles rau hnyav -cov haujlwm crane daim ntawv thov, tsim los ntawm "CR" prefix, xws li CR73 thiab CR100 (uas sawv cev rau qhov kwv yees qhov hnyav hauv kilograms ib 'meter'). Cov kev tsheb ciav hlau no tau tsim kho kom zoo kom haum rau cov log tshwj xeeb ntawm Japanese-tsim cranes thiab cov cuab yeej nqa hnyav.
