The invention discloses an anti-disengaging cross hinge device of an auxiliary lifting winding system. The anti-disengaging cross hinge device comprises a fixed pulley block and a guide pulley block;a steel wire rope is clockwise and alternately wound around a fixed pulley and a movable pulley of a fixed pulley block and a movable pulley block; the fixed pulley block is hung below the guide pulley block through a lifting tool; pair of guide pulleys parallel to each other is installed on the guide pulley block; one fixed pulley block is arranged under each guide pulley; the fixed pulley blockis provided with a steering pulley coaxial with the fixed pulley; the steel wire rope on each side penetrates out of a winch, penetrates through the guide pulley, passes through the steering pulley ona fixed pulley shaft on the right side, and then is alternately wound around the fixed pulley clockwise after passing through the movable pulley so as to realize winding of the hoisting steel wire rope. The steel wire ropes on the two sides are connected between the fixed pulley blocks; pulley shafts on the fixed pulley blocks are perpendicular to pulley shafts of the upper guide pulleys; and thepulley axis planes of one pair of fixed pulley blocks are parallel to the pulley axes of the upper guide pulleys. The anti-disengaging cross hinge device disclosed by the invention can adapt to large-amplitude transverse deflection and is more suitable for an offshore hoisting environment.

    本发明公布了一种防脱槽的副起升缠绕系统十字铰装置,包括定滑轮组、导向滑轮组,钢丝绳顺时针交替绕过定滑轮组和动滑轮组的定滑轮和动滑轮,定滑轮组通过吊具悬挂在导向滑轮组下方,该导向滑轮组上安装有相互平行的一对导向滑轮,每个导向滑轮正下方布置一组定滑轮组,该定滑轮组上设有与定滑轮同轴的转向滑轮,每一侧的钢丝绳从绞车出绳穿过导向滑轮,通过右侧定滑轮轴上的转向滑轮,再由通过动滑轮顺时针交替绕过定滑轮完成起升钢丝绳的缠绕。两侧钢丝绳在定滑轮组间相连,定滑轮组上的滑轮轴与上方的导向滑轮的滑轮轴相互垂直,一对定滑轮组的滑轮轴线平面平行于上方的导向滑轮的滑轮轴线。本发明能适应横向大幅偏摆,更加适应海上吊装环境。
