The invention discloses a combined cable collecting and releasing aviation winch cable arrangement device capable of being used for collecting and releasing cable arrangement of variable-cable-diameter variable-cross-section combined cables. The combined cable collecting and releasing aviation winch cable arrangement device comprises a lead screw supporting structure, a lead screw drive mechanism,a cable guide mechanism and an active traction mechanism. A motor I drives a lead screw to rotate through chain transmission. The cable guide mechanism and a lead screw nut do reciprocating linear movement along the lead screw. By controlling the rotating speed ratio of a drum motor and the motor I, variable-diameter cable arrangement can be achieved. By means of independent chain belts, conveying chains can have large bending radii within limited arc sections, and a large amount of space is saved compared with conventional pulley cable guide. A righting frame is designed into a beak shape onthe basis of the collision mechanics principle, and a streamline body which inclines can be effectively overturned and righted and can smoothly pass the cable arrangement device. By means of the active traction mechanism, the active traction and looseness prevention functions can be achieved by changing the spring expansion and contraction quantity and the rotating speed of a motor II to adjust the friction force exerted by rollers on the combined cables. The whole cable arrangement device is small in weight, small in size and particularly suitable for being used on aviation winches.
本发明公开一种组合缆收放航空绞车排缆装置,可用于变缆径变截面组合缆的收放排缆。包括:丝杠支撑结构、丝杠驱动机构、导缆机构和主动牵引机构。电机Ⅰ经链传动带动丝杠旋转,导缆机构和丝杠螺母沿丝杠做往复直线运动,通过控制卷筒电机和电机Ⅰ转速比,可实现变径排缆。独立的链带使得传送链可在有限弧段里实现较大弯曲半径,较常规滑轮导缆节省大量空间。扶正架基于碰撞力学原理设计成鸟嘴形状,可有效翻转回正倾斜的流线体,使其顺利通过排缆器。主动牵引机构可通过改变弹簧伸缩量和电机Ⅱ的转速调整辊子对组合缆的摩擦力大小,实现主动牵引和防松功能。整个排缆装置质量轻、体积小,特别适合在航空绞车上使用。
