Doubling Chain Double Layer Lines: Space Folding and the Industrial Revolution at Triple Speed

▋​​技术原理：空间折叠与倍速物理机制

倍速链双层线的核心突破在于​​空间折叠循环效应​​——通过上层输送满载工装板执行生产任务，下层专用于空载工装板高速回流，形成闭环流转系统。其物理基础是​Triple Speed Transmission Formula:.v = (1 + D/d) × v₀​（D为滚轮直径，d为滚子直径，D/d≥2）。滚轮与滚子的直径差使工装板速度达链条速度的3倍，而移载机通过气动顶升（精度±0.5mm）与皮带驱动，3秒内完成跨层转移，将空板回流时间压缩70%。
