Description

Systematic bundling method for high-voltage waste cables Technical Field The invention belongs to the field of packaging and logistics automation, and particularly relates to a systematic treatment method for compacting, bundling and gravity center positioning of waste high-voltage cable bundles. Background The recovery of the waste cable plays a key role in the recycling of copper resources. In view of the relative lack of copper resources in China, domestic copper supply mainly depends on recycling of waste cables, wherein high-voltage cables occupy an important proportion, and therefore, the improvement of waste cable recycling technology has important significance. Currently, used cables are usually excavated at a construction site, collected and transported to a warehouse. Before warehousing, each car of waste cable needs to be weighed, and the waste cable is hoisted and warehoused integrally through a hoisting steel cable which is padded at the bottom of the cable in advance. The steel cable is always kept at the bottom of the cable in the storage process so as to facilitate subsequent transportation. Each bundle of cables is of different specifications, typically between 50 and 137 mm in diameter and about 5 to 6 meters in length, with a single cable weighing up to 120 kg. Because of the flexibility of the cable, which is often in a slightly curved state, it is prone to twisting (its curvature can be defined by the length and width dimensions of the smallest bounding rectangle, in this case the maximum curvature is about 1 meter lateral offset per 6 meters length). At present, the storage mode of cables in a warehouse is disordered, cables with different specifications are stacked in disorder, and as the warehouse-in cables are increased, the stacking finally forms a pyramid-shaped structure. The stacking mode not only affects the overall look and feel, but also has the problems of low space utilization rate, large potential safety hazard and the like.

The technical scheme adopted by the method is that cable wires are pre-clamped, then the cable wires are bound in a circle (also called as arrow-penetrating binding in the industry), and the cable wires are carried away after the binding is finished. But only focuses on the bundling and fastening problem of the cable bundles, which does not involve the problem of the gravity center of the bundled cable bundles in the horizontal direction, if the balance point (gravity center or mass center) of the cable bundles is not known, the stability and the safety of the forklift are not good for the hoisting process of the bundled cable bundles.
