The invention relates to the technical field of winches, and discloses an accidental weightless falling avoiding assembly for winch hoisting. The assembly comprises an anti-weightlessness mechanism, wherein a rotating shaft is rotatably connected to the internal center of the anti-weightlessness mechanism, a fixed plate is movably connected to the outer side of the rotating shaft, a rotating plate is movably connected to the outer side of the fixed plate, special-shaped blocks are movably connected to the outer side of the rotating plate, and special-shaped grooves are movably connected to the outer sides of the special-shaped blocks. According to the accidental weightless falling avoiding assembly for winch hoisting, a rope disc moves outwards to extrude triggering support hands to move, the triggering support hands push pushing rods and connecting blocks to move outwards, electrorheological fluid in expansion blocks is powered on when control contacts and secondary contacts are in a closed state, movable mechanisms push rotating tables to move towards the inner side, the rotating tables limit the movement of fixed heads, the weightless state of a winch is limited, and therefore the working safety of the winch is improved.

    本发明涉及卷扬机技术领域,且公开了一种卷扬机起重用避免意外失重下坠组件,包括防失重机构,所述防失重机构内部的中心转动连接有转轴,转轴的外侧活动连接有固定板,固定板的外侧活动连接有转动板,转动板的外侧活动连接有异形块,异形块的外侧活动连接有异形槽。该卷扬机起重用避免意外失重下坠组件,通过绳索盘向外侧运动,进而使绳索盘挤压触发托手运动,从而使触发托手推动推杆和连接块向外侧移动,进而通过控制触头和二级触头的闭合状态,会使膨胀块内部的电流变体得电,进而使活动机构推动转动台向内侧运动,从而使转动台限制固定头的运动,从而使卷扬机的失重状态被限制,进而提高了卷扬机的工作安全性。
