简体中文 Hey, have you also encountered this situation? The roller line in the factory climbed a slope, the boxes clattered and slid down, the workers chased and ran faster than the production line ......A 30° incline sounds fierce, but can it really be used on a tumbleweed?What? Today we will nag some real, special treatment of all kinds of "slope not serve"!
🔍 I. Is it okay to climb 30° or not? Splash cold water first!
To tell the big truth.A regular roller line going up a 30° hill? It's basically the same as asking a sedan to climb a cliff!Why so absolute?
- The physical limits are there.Ordinary power roller lines rely on friction to drive the material, the greater the slope, the stronger the gravity force. Once the slope exceeds the "sticky strength" of the material and the drum, the slippery slope is no discussion.
- Older drivers in the industry know this.::
- Belt conveyor: limit slope ≈ 18 ° (more steep material rolling to you)
- Chain Conveyor: barely holds up to 30° (also the chain has to carry it hard, at the cost of crazy wear and tear)
- Roller line? 15° capped!This is the "deluxe" version with anti-slip measures.
📌(knock on the) blackboardDon't believe the adverts for "30° easy climbing"!Double the failure rate for every 1° increase in gradient and you're not bluffing!. Don't believe me? Go to the workshop and ask the master who has not repaired equipment for steep slopes!
🕳️ Second, the slope design of the three pits, step in one of the overturned car
The newbie is most likely to get screwed in the link, let's go straight to the case:
The Pit 1️⃣."Slope overruns, materials skate en masse."
An e-commerce warehouse to save trouble, directly dislike the slope to 20 °. As a result, the carton is like sitting on a slide, the sorter every day staged "100 metres after the box".Then it dropped to 12° + roller wrap, instant honesty!.
✅lit. password for avoiding a pit (idiom); to avoid a pitfall by avoiding words: Slope ≤ 10° for light goods and ≤ 8° for heavy goods! Want it steeper?Addition of edge and friction stripsDon't be a head iron.
The Pit 2️⃣."Not enough power to turn the roller into a pendulum."
An auto parts factory to 10 metres of climbing line with a 0.5kW small motor, the results of the drum turned slower than a snail, the workpiece is stuck in the half-slope "swing".The line was later saved by replacing it with a 1.5kW inverter motor + double sprocket drive.
✅lit. password for avoiding a pit (idiom); to avoid a pitfall by avoiding words:.Motor power ≥ (slope factor × total load)! For every 5° increase in slope, add 20% of power to keep you safe.
The Pit 3️⃣."The slope goes up and down, and the equipment retires early."
Ever seen a "wavy" climbing line? A food factory to save space, the slope from 10 ° → 15 ° → 8 ° back and forth. As a result, the chain collapsed three times a month, and the repair cost was enough to buy half a new line!
✅lit. password for avoiding a pit (idiom); to avoid a pitfall by avoiding words:.Slope change ≤2°! Cushion guide added to the articulationDon't let the equipment "rollercoaster".
🛠️ III. Anti-skid tricks: wild ways to make materials "climb steadily"
For all intents and purposes.Anti-skid is the lifeblood of ramps! These three tricks work well in person:
-
Rubber-coated rollers + fish scale pattern
Rubber surface layer carved deep grooves, the coefficient of friction soared to 0.6! A logistics centre with this trick, 15 ° slope to transport tyres as stable as an old dog.
→Cost +15%, maintenance rate -40% -
Pinned edges
Like "anti-derailment strips" for train tracks, they must be fitted when the gradient exceeds 10°! Spacing according to cargo size (The width of the box is 30cm, the interval between the edges is ≤15cm.). -
Power Segment Layout
Don't die on the long slopes with "one head drive"!Auxiliary motors every 5 metresIt's like having a few more pushers on the way up a mountain.
⚡ Fourth, slope power saving metaphysics: the angle is adjusted, the electricity bill is half less
You think the slope only affects safety?It's also the switch for the "electric tiger".!
- case (law): An automobile factory sloped its assembly line from 12° → 9°, although the line was extended by 3 metres.Save 20,000+ on your monthly electricity bill(Motor Load ↓35%)
- The Golden Formula::
For every 1° drop in slope ≈ 5% reduction in energy consumption
For every 0.1m/s reduction in speed ≈ 8% reduction in energy consumption
→Small gradient + steady speed = smiling boss!
📋 V. The Ultimate Selection Chart: Copy it and you'll be safe from lightning!
Directly dump dry goods, choose equipment against this table is correct:
| parameters | safety value | default value | Response programme |
|---|---|---|---|
| slope angle | ≤15° | ＞18° | Demolition section descending slope + anti-slip rollers |
| Single drum load | ≤150kg | ＞200kg | Change of heavy-duty sprocket drive |
| Motor power | ≥80W per metre | <50W per metre | Power x 1.5 with inverter |
| ramp articulation | Slope difference ≤2° | Slope difference >5° | Add 10cm curved transition section |
💡The White Mantra:.Slope should be less than more, power should be more than less, and anti-slip should be more than less!
💬 Write at the end: a personal opinion blitz
After ten years of designing conveyor lines, I've seen too many fiascoes of disliking the slope to save space.It's not true that the bigger the slope, the better.--The workshop is not a playground.A safe, money-saving slope is a good slopeI'm sorry. The next time someone tells you "30° is fine", just throw this in their face!
