The invention discloses a steel wire rope winding device which comprises a power part, a fixing frame, a spline shaft, a steel wire rope reel, a nut plate, a rotary frame, a rope guiding wheel and a rope pressing wheel. The spline shaft is arranged on the fixing frame and connected with the power part, and the steel wire tope reel is movably arranged on the spline shaft in a sleeved mode. Due to the fact that the reel is meshed with the nut plate and can move along the spline shaft, when a steel wire rope is wound into or unwound out of a pulley and the reel, declination is completely avoided, in other words, the declination angle of the steel wire rope is zero degree, and therefore even if limitation of the structural size exists, for example, the center distance between the reel and the pulley is quite small, the phenomenon that due to the excessively-large declination angle of the steel wire rope, the steel wire rope is impacted and rubbed with the lateral side of a rope groove or the steel wire rope jumps out of the groove can be avoided.
