The invention discloses a winch characterized of being fixed in steel wire rope winding and unwinding position. The winch comprises a fixing nut, a winding drum, a ball screw and a ball spline shaft.The ball screw is arranged on the middle section of the winding drum, one end of the winding drum is connected with the ball spline shaft, and the exterior of the ball screw is fixedly arranged through the fixing nut. Steel wire ropes can be kept on one plane all the time when the steel wire ropes are wound and unwound by the winch, the position of the nut is fixed, the winding drum can conduct back-and-forth movement in the up-and-down direction, and therefore the steel wire ropes are stored in spiral grooves of the winding drum in a circle mode. A new technical scheme is provided for the usage on certain occasions with the mechanical requirement that the steel wire ropes need to be continuously wound and unwound back and forth and need to be kept on one plane, and the vacancy of the function of an existing winch is filled.
本发明公开了一种钢丝绳收放位置固定的卷扬机,包括固定螺母、卷筒、滚珠丝杆和滚珠花键轴,所述卷筒的中段设有滚珠丝杆,卷筒的一端连接有滚珠花键轴,滚珠丝杆的外部通过固定螺母固定设置,本发明卷扬机在收放钢丝绳时能够使钢丝绳一直保持在一个平面上,螺母位置不动,卷筒能上下来回往返运动,从而把钢丝一圈一圈收纳在卷筒的螺旋沟槽上。对于一些需要钢丝绳不断来回收放,并且必须保持在一个平面上的机械要求的场合使用,提供了一种新的技术方案,填补了目前卷扬机的功能上的空缺。
