Referring to fig. 1, fig. 1 is a specific case of a first layer of a steel wire rope wound on a cigarette tube, an end of a conventional steel wire rope is generally fixed to one end of a winding tube, then the other end of the conventional steel wire rope is wound, after the steel wire rope is wound to the other end of the winding tube, the steel wire rope is gradually lifted up to a second layer by using a reaction force of a guard plate on the end face of the winding tube, and then reverse dislocation winding of the second layer is started. When the steel wire rope is reversely wound on the second layer to one end close to the end of the steel wire rope, the end of the steel wire rope exists on the first layer. For this purpose, a certain gap is present between the first layer of steel cables and the cover plate at the corresponding end, which gap is denoted by a in fig. 1. Generally the gap is slightly smaller than or equal to the diameter of the entire steel cord. Referring to fig. 2, fig. 2 is a detail of a second layer of wire rope wrapped on a cigarette tube; when the second layer of steel wire rope is wound to the upper part of the gap between the first layers, the steel wire rope can fall into or extrude into the gap due to the reaction tension of the heavy object, so that the whole winch drum and the steel wire rope vibrate, and the steel wire rope is easy to break due to sudden vibration except the abrasion of the steel wire rope, so that potential safety hazards are caused. When the steel wire rope is wound to the second layer and turns to the third layer, the steel wire rope on the third layer starts to be wound normally due to the support of the steel wire rope, which is squeezed into the gap between the first layers, of the second layer.
