The invention provides an eight-rope double-winding-drum lifting device which comprises an upper frame connected with a lifting appliance, two sets of first pulley blocks are arranged on each of the two sides of the upper frame in the first direction, and two sets of second pulley blocks are arranged on each of the two sides of the upper frame in the second direction; the two lifting winding drums are connected to the trolley assemblies located on the two sides of the upper portion of the upper frame correspondingly. The first ends of the four first steel wire ropes are respectively wound on the lifting winding drum, and the second ends respectively bear the first pulley block and then are independently connected to a first micro-motion mechanism capable of moving along the second direction; first ends of four second steel wire ropes are respectively wound on the lifting winding drum, second ends of the four second steel wire ropes respectively bear a second pulley block and then are connected to two sides of a second micro-motion mechanism which can move along the first direction and can be used as a rotating shaft to perform central autorotation along the first direction, and when the lifting winding drum synchronously and reversely rotates, the lifting appliance ascends and descends along a third direction. The lifting appliance can move based on freedom degrees in six directions, the working efficiency is improved, and the service life of the pulley is prolonged.

    本发明提供了一种八绳双卷筒起吊装置,包括:连接吊具的上架,上架的第一方向的两侧各自设有两套第一滑轮组,上架的第二方向的两侧各自设有两套第二滑轮组;两起升卷筒,分别连接于位于上架上方两侧的小车组件;四第一钢丝绳的第一端分别缠绕于起升卷筒,第二端分别承载第一滑轮组后独立连接到可沿第二方向运动的一第一微动机构;四第二钢丝绳的第一端分别缠绕于起升卷筒,第二端分别承载第二滑轮组后连接到可沿第一方向运动并且可以第一方向作为旋转轴进行中心自转的第二微动机构的两侧,当起升卷筒同步反向转动时,吊具沿第三方向升降。本发明能够实现吊具基于6个方向自由度运动,提高工作效率和滑轮的寿命。
