Description

Technical Field

[0001] The utility model relates to the technical field of steel ropes, and more specifically, to a steel rope with impact resistance, wear resistance and tear resistance. Background Technique

[0002] A steel rope is a helical steel wire bundle formed by twisting steel wires that meet the requirements of mechanical properties and geometric dimensions together according to certain rules. The steel rope consists of steel wires, a rope core and grease. First, multiple layers of steel wires are twisted into strands, and then, with the rope core as the center, a certain number of strands are twisted into a helical rope. In material handling machinery, it is used for lifting, traction, tensioning and load bearing. The steel rope has high strength, light self-weight, stable operation, and is not likely to break suddenly as a whole, and is reliable in work.

[0003] The existing steel rope is helically wound outside the rope core. When a rotational force is generated during the stretching of the steel rope, it is easy to cause the ropes wound outside the steel rope to become loose, thereby reducing the strength of the steel rope. And when an external impact occurs, it directly acts on the steel rope, which is likely to cause the ropes wound outside to be deformed due to extrusion, reducing the overall strength. Therefore, a steel rope with impact resistance, wear resistance and tear resistance is proposed. Content of the Utility Model

[0010] Preferably, a support isolation layer is injection-molded at the gaps between multiple steel wires of the inner layer steel wire ropes and the outer layer steel wire ropes, and the support isolation layer can be made of rubber material.

[0011] Preferably, the first wrapping net rope is made of carbon fiber material, and the second wrapping net rope and the third wrapping net rope are made of ceramic fiber material.

[0012] Preferably, the insulating layer can be made of rubber material. The insulating layer is injection-molded and wrapped on the outer surface of the third wrapping net rope, and the fixing ring and the stabilizing connecting rod are both arranged in the middle of the insulating layer.
