Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire rope production equipment, specifically a stress relief device for the wire rope production process. Background Technology
[0002] Steel wire rope is an important component made of multiple twisted steel wires, with extremely wide applications. It is typically made by first twisting the steel wires into strands, and then combining these strands into a rope, resulting in a compact structure and high strength. With its excellent tensile, torsional, and fatigue resistance, it is used in construction for hoisting heavy objects and erecting scaffolding; in transportation, it is a key traction component in elevators, cable cars, and cranes; and in mining, it undertakes heavy tasks such as ore hoisting and equipment lifting. Each step in the steel wire rope production process introduces varying degrees of stress into the rope, which significantly impacts its performance, quality, and subsequent safety during use.
[0003] Utility model patent CN218812860U discloses a heating device for eliminating internal stress in steel wire ropes. The device includes a heating chamber composed of multiple oil-filled heating boxes connected in series, with an oil return groove at the connection point of each heating box. The heating boxes and the oil return groove together form a heating channel for stress relief of the steel wire rope. An oil tank is configured with one oil tank for every two heating boxes, enabling oil-heat circulation between the oil tank and the heating boxes. This utility model relieves stress in steel wire ropes by heating with oil temperature. The continuity and thermal stability of the oil temperature improve the stress relief effect on the steel wire rope, making the stress relief process more gentle and stable, thus improving the quality of the steel wire rope. Furthermore, the heating chamber is formed by multiple heating boxes connected in series, with each pair of heating boxes paired with an oil tank, making the entire heating chamber highly manufacturable and easy to manufacture.
[0004] However, the current device for eliminating internal stress in wire ropes consumes a lot of energy and has high production costs because it eliminates stress through a heat treatment valve. At the same time, high-temperature treatment may also have a certain negative impact on the mechanical properties of the wire rope, such as reducing its toughness. Therefore, a stress elimination device for wire rope production process is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a stress relief device for the production process of steel wire ropes, which has the advantages of quickly eliminating stress in steel wire ropes in a low-energy-consumption manner, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A stress relief device for steel wire rope production includes a mounting base plate, a mounting back plate fixedly mounted on the top of the mounting base plate, a mounting frame fixedly mounted on one side of the mounting back plate, two mounting lugs fixedly mounted on each of the two inner sidewalls of the mounting frame in the vertical direction, a support arm rotatably mounted inside the mounting lugs, a support shaft fixedly mounted on one side of the support arm, a guide wheel rotatably mounted on one end of the support shaft, and a stress relief component provided on one side of the mounting back plate.
[0008] The stress relief assembly includes three vibration shafts rotatably mounted on one side of the mounting back plate. The vibration shafts are driven by a drive mechanism. One end of each vibration shaft is fixedly mounted with a vibration eccentric wheel. The three vibration eccentric wheels are respectively located above the upper horizontal section of the wire rope, below the lower horizontal section of the wire rope, and on one side of the vertical section of the wire rope.
[0009] Furthermore, the drive mechanism includes three vibration motors fixedly installed on one side of the mounting back plate, and the output shafts of the three vibration motors are respectively fixedly connected to one end of the three vibration shafts.
[0010] Furthermore, a movable lug is fixedly installed on one side of the support arm, and a spring telescopic rod is rotatably installed inside the movable lug.
[0011] Furthermore, two fixed lugs are fixedly installed on each of the two inner sidewalls in the vertical direction of the mounting frame, and one end of the spring telescopic rod is rotatably connected to the fixed lug.
[0012] Furthermore, a sliding limiting groove is fixedly installed on the top of the mounting base plate, and a sliding base is slidably installed inside the sliding limiting groove.
[0013] Furthermore, two winding uprights are fixedly installed on the top of the sliding base, and a winding shaft is rotatably installed between the two winding uprights.
[0014] Furthermore, a movable screw is rotatably mounted on the inner wall of the sliding limiting groove, and the movable screw is threadedly connected to the sliding base.
[0015] Furthermore, a moving motor that drives the moving screw to rotate is fixedly installed on one side of the sliding limiting groove, and a winding motor that drives the winding shaft to rotate is fixedly installed on one side of the winding upright plate.
[0016] Compared with the prior art, this utility model provides a stress relief device for the steel wire rope production process, which has the following beneficial effects:
[0017] This stress relief device in the wire rope production process works by winding the wire rope around the surfaces of four guide wheels, forming a rectangular shape. The rotation of the vibration shaft drives the rotation of the vibration eccentric wheel, causing the wire rope to vibrate and eliminate the stress on the wire rope. This solves the problem of stress relief devices that eliminate internal stress in wire ropes. However, stress relief through heat treatment valves consumes a lot of energy and has high production costs. In addition, high-temperature treatment may have a certain negative impact on the mechanical properties of the wire rope. Attached Figure Description

[0024] Please see Figures 1 to 4 This embodiment describes a stress relief device for steel wire rope production, comprising a mounting base plate 1, a mounting back plate 2 fixedly mounted on the top of the mounting base plate 1, a mounting frame 3 fixedly mounted on one side of the mounting back plate 2, two mounting lugs 4 fixedly mounted on each of the two inner sidewalls of the mounting frame 3 in the vertical direction, a support arm 5 rotatably mounted inside the mounting lug 4, a support shaft 6 fixedly mounted on one side of the support arm 5, a guide wheel 7 rotatably mounted on one end of the support shaft 6, and a stress relief assembly provided on one side of the mounting back plate 2. (Steel wire rope installation) Figure 1 The direction shown goes around the four guide wheels 7.
[0025] The stress relief assembly includes three vibrating shafts 8 rotatably mounted on one side of the mounting back plate 2. The vibrating shafts 8 are driven by a drive mechanism, and a vibrating eccentric wheel 9 is fixedly mounted at one end of each shaft 8. The three vibrating eccentric wheels 9 are located above the upper horizontal section of the wire rope, below the lower horizontal section of the wire rope, and on one side of the vertical section of the wire rope, respectively. The vibrating shafts 8 drive the vibrating eccentric wheels 9 to rotate, causing the wire rope to vibrate at three different positions, thus relieving the stress on the wire rope.

[0032] Secondly, a movable screw 18 is rotatably installed on the inner side wall of the sliding limit groove 14, and the movable screw 18 is threadedly connected to the sliding base 15.
[0033] Finally, a moving motor 19, which drives the moving screw 18 to rotate, is fixedly installed on one side of the sliding limit groove 14, and a winding motor 20, which drives the winding shaft 17 to rotate, is fixedly installed on one side of the winding stand 16. The moving motor 19 drives the moving screw 18 to vibrate, which in turn drives the sliding base 15 to move, and then drives the winding shaft 17 to move, so that the wire rope is evenly wound onto the winding shaft 17.
[0034] The working principle of the above embodiment is as follows: wire rope installation Figure 1 The direction shown bypasses four guide wheels 7. The vibration motor 10 drives the vibration shaft 8 to rotate, which in turn drives the vibration eccentric wheel 9 to rotate, causing the wire rope to vibrate in three positions and eliminating the stress on the wire rope.
