The invention provides a rope discharging method of a lower limiting device of a steel wire rope, which comprises the following specific steps: (1) when a layer of steel wire rope is wound on a winding drum, lifting a compression roller by the steel wire rope, separating the compression roller from the surface of the winding drum, identifying that the steel wire rope does not reach a lower limiting position, and normally putting down the winding drum; (2) the winding drum begins to rotate and performs lowering action until the steel wire rope on the winding drum remains n circles, the steel wire rope is separated from the lower part of the compression roller, so that the compression roller is tightly pressed on the surface of the winding drum, and at the moment, the steel wire rope is preset and identified to reach a lower limiting position; (3) after a layer of steel wire rope is wound on the winding drum, the steel wire rope is separated from the surface of the winding drum, the travel switch does not work, when the steel wire rope reaches a preset steel wire rope lower limit position, the steel wire rope is discharged in the direction of the inclined part of the pressing roller, and after rope discharging, the pressing roller presses downwards due to the fact that the pressing roller is attached to the surface of the winding drum; therefore, the spring of the spring device is driven to recover the natural state, the rope discharging action is completed, and the rope releasing action is smoother.
本发明提供了一种钢丝绳的下限位装置的出绳方法,具体步骤包括:(1)在卷筒上缠绕一层钢丝绳时,压辊被钢丝绳抬起,与卷筒表面进行分离,识别为钢丝绳没有到达下限位位置,卷筒正常进行下放动作;(2)卷筒开始转动并进行下放动作,直到卷筒上的钢丝绳剩余n圈时,钢丝绳脱离压辊的下方,使得压辊紧压在卷筒的表面,此时预设识别为钢丝绳到达下限位位置;(3)在卷筒上缠绕一层钢丝绳后,钢丝绳与卷筒表面分离,行程开关不工作,当钢丝绳达到预设的钢丝绳下限位置时,钢丝绳在沿着压辊的倾斜部方向出绳,出绳后由于压辊与卷筒表面贴合,从而使得压辊向下下压,从而带动弹簧装置的弹簧恢复自然状态,完成出绳动作,下放绳动作更加顺畅。
