The invention relates to the technical field of lifting machinery, and provides a chain lifting device and an electric chain hoist, the chain lifting device comprises a chain wheel, a chain, an outer contour limiting device and a shell, and the chain wheel is used for being connected with a driving shaft; the other end of the chain is positioned on the other side of the chain wheel after bypassing the chain wheel; the outer contour limiting device is arranged on the side, away from the chain wheel, of the chain along the rotating path of the chain and used for limiting the outer ring track of the rotating path of the chain. The outer contour limiting device is sleeved with the shell, and the shell is used for limiting the outer contour limiting device. According to the chain lifting device provided by the invention, the shell is arranged on the outer side of the outer contour limiting device, and the limitation of factors such as chain wheel design experience and high-precision chain manufacturing requirements in the aspect of chain and chain wheel production design can be broken through on the premise of ensuring no chain clamping and no chain falling on the basis that the shell powerfully supports the outer contour limiting device; the economic benefit is improved.

    本发明涉及升降机械技术领域,提供一种链条提升装置和电动环链葫芦,链条提升装置包括链轮、链条、外轮廓限位装置和外壳,链轮用于与驱动轴连接;链条的一端位于链轮的一侧,另一端绕过链轮后位于链轮的另一侧;外轮廓限位装置沿链条的转动路径,设于链条远离链轮的一侧,外轮廓限位装置用于限制链条的转动路径的外圈轨迹;外壳套设于外轮廓限位装置的外侧,用于对外轮廓限位装置进行限位。本发明提供的链条提升装置,通过在外轮廓限位装置的外侧设置外壳,基于外壳对外轮廓限位装置的有力支撑,可以在保证不卡链、不脱链的前提下,打破链轮设计经验以及高精度链条制造要求等因素在链条和链轮生产设计方面的限制,提高经济效益。
