The invention discloses a crane rope rolling type power returning device. The crane rope rolling type power returning device comprises two oppositely-arranged lateral plates, three equal-distance first rollers, two second rollers and an adjusting screw, wherein the axes of the three first rollers are located on the same plane, and the two ends of the first rollers are connected with the two lateral plates respectively and rotationally; the two second rollers are parallel to the first rollers, the distance between the second rollers is the same as the distance between the first rollers, and the two ends of the second rollers are connected with the two lateral plates respectively through sliding blocks; and the adjusting screw is arranged at one ends of the lateral plates and connected with the sliding blocks. The plane where the axes of the first rollers are located is parallel to the plane where the axes of the second rollers are located, a certain distance is reserved between the two planes, and therefore gaps for a steel wire rope to penetrate are formed between the first rollers and the second rollers; sliding grooves where the sliding blocks are installed are arranged in the lateral plates; and when the adjusting screw is adjusted, the sliding blocks drive the first rollers to break away from and get close to the second rollers. The crane rope rolling type power returning device can be used for producing a component part of a new crane with a power returning function itself, and has the beneficial effects of being simple in structure and convenient to use; and the twisting force is rapidly released in the using process of the steel wire rope.
