The invention discloses a manual chain hoist with a rapid lifting clutch device. The manual chain hoist comprises a speed reducer, a loading mechanism, a clutch mechanism and a driving mechanism; thespeed reducer, the loading mechanism, the clutch mechanism and the driving mechanism are sequentially arranged on a transmission shaft; the loading mechanism is provided with a loading chain; the clutch mechanism can enable the transmission shaft to be separated from the speed reducer for speed reduction engagement; and the driving mechanism is provided with a drive chain. A gear set of the speedreducer comprises a double-layer gear and a secondary gear; two small gears of the double-layer gear are respectively engaged with an outer ring of the secondary gear; two large gears of the double-layer gear are respectively engaged with the transmission shaft; an inner ring of the secondary gear is engaged with the loading mechanism; the double-layer gear is arranged in a gear box through a gearcolumn; and a box cover is connected with the gear box through a bolt. According to the manual chain hoist with the rapid lifting clutch device, by adopting the clutch mechanism, the transmission shaft and the speed reducer can be remotely separated, the loading chain can be quickly reset, manual operation is not needed, the operation convenience is improved, and the operation safety is improved.

    本发明公开了一种具有快速升降离合装置的手动环链葫芦,包括依次设置于传动轴上的减速器、负载机构、离合器和驱动机构,负载机构上设置有负载链,离合机构能够使传动轴脱离减速器中减速啮合,驱动机构上设置有驱动链。减速器的齿轮组包括双层齿轮和二级齿轮,两个双层齿轮的小齿轮分别与二级齿轮的外圈啮合,两个双层齿轮的大齿轮分别与传动轴啮合,二级齿轮的内圈与负载机构啮合,双层齿轮通过齿轮柱设置于齿轮箱内,箱盖与齿轮箱通过螺栓连接。本发明的具有快速升降离合装置的手动环链葫芦,采用的离合机构能够实现远程分离传动轴与减速器,可以快速复位负载链,不必人工手动操作,增加了操作的便利性,增加了操作的安全性。
