Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel wire rope, and in particular to a polymer core steel wire rope. Background Technology
[0002] A wire rope is a helical bundle of steel wires twisted together according to specific rules, meeting requirements for mechanical properties and geometric dimensions. It consists of steel wires, a core, and lubricant. The process involves first twisting multiple layers of steel wires into strands, then winding a certain number of strands around the core to form a helical shape. In material handling machinery, it is used for lifting, traction, tensioning, and load-bearing. Wire ropes are characterized by high strength, light weight, smooth operation, and resistance to sudden breakage, ensuring reliable operation.
[0003] In the existing technology, the outer surface of the metal core of most steel wire ropes is twisted by only a single layer of steel strands, which results in insufficient tensile strength of the steel wire rope. Utility Model Content
[0004] The present invention aims to overcome the shortcomings of insufficient tensile strength in existing steel wire ropes by providing a polymer core steel wire rope that improves tensile strength.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A polymer core steel wire rope includes a core and several strands. The strands are evenly wound around the outer surface of the core. Each strand includes a central wire, several inner wires, and several outer wires. The inner wires are evenly wound around the outer surface of the central wire and then twisted to form an inner core. The outer wires are evenly wound around the outer surface of the inner core.
[0007] Several strands are evenly wound around the outer surface of the rope core. Each strand includes a central wire, several inner layer wires, and several outer layer wires. The inner layer wires are evenly wound around the outer surface of the central wire and then twisted to form an inner core. The outer layer wires are evenly wound around the outer surface of the inner core. The strands are evenly wound around the outer surface of the rope core, and simultaneously, with the central wire as the center, the strands are twisted into a double-layered solid structure through the outer and inner layer wires. Compared to steel wire ropes with a thinner strand structure, this design, to a certain extent, improves tensile strength.
[0008] Preferably, the rope core is made of twisted polymer industrial filaments. The rope core is prepared using polymer industrial filaments, which are generally made of polyethylene or polyester, and possess waterproof, oil-proof, and tough properties.
[0009] Preferably, the center wire, inner layer wire, and outer layer wire are all steel wires.
[0010] Preferably, several strands are tightly twisted in a spiral around the outer surface of the rope core, which helps to ensure stable rope diameter, strong texture, and improve the bending performance and toughness of the strands; the space between the strands and the rope core is filled with grease, which can play a lubricating role and reduce friction.
[0011] Preferably, several inner layer filaments are spirally twisted around the outer surface of the central filament. This improves the strength of the twist between the inner layer filaments and the central filament, ensuring stable rope diameter and a robust texture.
[0012] Preferably, several outer layer filaments are spirally twisted around the outer surface of the inner core. This further improves the strength of the twist between the outer layer filaments and the inner core, ensuring stable rope diameter and a robust texture.
[0013] The beneficial effects of this utility model are: to a certain extent, it achieves the purpose of improving tensile strength; the use of high-polymer industrial filaments for the preparation of the rope core has the characteristics of being waterproof, oil-proof, and having good toughness; it helps to ensure stable rope diameter, strong texture, and improve the bending performance and toughness of the rope strands; the grease can play a lubricating role and reduce friction.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0018] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of components illustrated in these embodiments do not limit the scope of this application. For ease of illustration, spatial relative terms such as “upper,” “lower,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “below” other elements or features would be fixed “upper” to other elements or features. Thus, the exemplary term “lower” can include both upper and lower orientations. The device may be fixed in other ways (rotated 90 degrees or located in other orientations), and the spatial relative descriptions used herein can be interpreted accordingly. It should also be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale. Techniques, processes, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, processes, and equipment should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limiting. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be discussed further in subsequent figures.
[0019] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0020] like Figure 1 In the embodiments described, a polymer core steel wire rope includes a core 1 and several strands 2, wherein the strands 2 are evenly wound around the outer surface of the core 1.
