Description

Technical Field

[0001] This utility model relates to the field of wire rope technology, and in particular to an ultra-low torque resistance rotating wire rope. Background Technology

[0002] In environments with significant lifting heights, there are high requirements for the anti-rotation performance of wire ropes. Traditional wire ropes, due to their large torque, are prone to twisting and tangling during use, affecting the safety and efficiency of large-scale tensile operations such as lifting.

[0003] Existing wire ropes have the problems of having a large number of strands, small wire diameter, and being prone to wear, which greatly reduces the service life of the wire rope. Therefore, there is a need for an ultra-low torque resistance rotating wire rope. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-low torque resistance rotating steel wire rope, which solves the problems of existing technologies where there are many strands, small wire diameters, easy wear, and greatly reduced service life of the steel wire rope.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultra-low torque resistance rotating steel wire rope, comprising an inner core rope, an inner hinged steel wire rotatedly wound around the outside of the inner core rope, an outer hinged steel wire rotatedly wound around the outside of the inner hinged steel wire, and a lubricating grease is coated between the outer hinged steel wire and the inner hinged steel wire.

[0006] Preferably, the inner core rope is formed into a multi-strand structure using a high-strength, low-elongation polyester fiber material twisting process, wherein the inner core rope is twisted to the right.

[0007] Preferably, the inner stranded steel wire is made of high carbon steel wire twisted into multiple strands, and the multiple strand structure is 35×7, wherein the inner stranded steel wire is twisted to the left.

[0008] Preferably, the outer stranded wire is made of alloy steel wire and has a multi-strand structure of 19×7, wherein the outer stranded wire is twisted to the right.

[0009] Preferably, both the outer and inner hinged steel wires are fully coated with lubricating grease.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting an inner core rope, which is made of high-strength, low-elongation synthetic material, the tensile strength and extrusion resistance of the wire rope are improved, ensuring safety under tension. By using a special twisting process to form a multi-layer strand structure, with the twisting direction of each layer of wires set in opposite directions, the overall torque of the wire rope is effectively reduced, avoiding the problem of twisting and entanglement.

[0012] 2. By setting externally twisted steel wires, the steel wire material has high strength and toughness after heat treatment, which meets the breaking tensile strength requirements of the wire rope for lifting operations. The opposite twist direction effectively reduces torque, and the surface is coated with grease or anti-rust oil, which reduces friction and wear between steel wires and extends the service life of the wire rope.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figure 1-3 As shown in the figure, an ultra-low torque resistance rotating steel wire rope includes an inner core rope 1, an inner hinged steel wire 2 is rotatably wound around the outside of the inner core rope 1, an outer hinged steel wire 4 is rotatably wound around the outside of the inner hinged steel wire 2 in the opposite direction, and a lubricating grease 3 is coated between the outer hinged steel wire 4 and the inner hinged steel wire 2.

[0020] The inner core rope 1 is made of high-strength, low-elongation polyester fiber material and is twisted to form a multi-strand structure. The inner core rope 1 is twisted to the right, which improves the tensile strength and compressive strength of the wire rope.

[0021] The inner strand 2 is made of high carbon steel wire twisted into multiple strands, and the multiple strand structure is 35×7. The inner strand 2 is twisted to the left and has high strength and toughness after heat treatment.

[0022] The outer strand 4 is made of alloy steel wire and has a multi-strand structure of 19×7. The outer strand 4 is twisted to the right, and the opposite twist direction effectively reduces the torque.

[0023] Both the outer stranded wire 4 and the inner stranded wire 2 are fully coated with grease 3. The grease 3 or rust-preventive oil coating reduces friction and wear between the wires and extends the service life of the wire rope.

[0024] Working principle: The inner core rope is made of polyester fiber material with right-hand twisting. The outer inner strand steel wire 2 is wrapped around the outside of 1 with left-hand multi-strand twisting. The outer strand steel wire 4 is further wrapped around the outside with reverse multi-strand twisting. A multi-layer strand structure is formed by using a special twisting process. The twisting direction of each layer of steel wire is set in opposite directions. The surface of the steel wire rope is coated with grease 3 to effectively reduce the friction between the steel wires.
