Description

Technical Field

[0001] This utility model relates to the field of copper-clad steel grounding wire straightening technology, specifically a straightening device for copper-clad steel grounding wires. Background Technology

[0002] In the field of power engineering, grounding systems play a crucial role in ensuring the safe operation of electrical equipment and the safety of personnel. Copper-clad steel grounding wires, due to their combination of the excellent conductivity of copper and the high strength of steel, are widely used in various grounding projects. After manufacturing, copper-clad steel grounding wires are usually wound into coils for easy storage and transportation. However, during the winding process, the grounding wire is subjected to bending stress, resulting in residual stress inside. Upon unwinding, this residual stress causes the grounding wire to exhibit varying degrees of bending, twisting, and other deformations, affecting its performance and installation effectiveness in actual use.

[0003] Currently, straightening machines are mostly used to straighten grounding wires. However, most straightening machines can only straighten specific diameters, meaning they have a limited range of applications. In addition, because the copper layer of copper-clad steel grounding wires is relatively thin, the distance between the two straightening rollers needs to be adjusted during the straightening process to avoid the copper layer peeling off or the internal structure of the grounding wire being damaged due to insufficient or excessive straightening. Utility Model Content

[0004] The purpose of this invention is to provide a straightening device for copper-clad steel grounding wires, which can adjust the spacing between the straightening rollers to accommodate grounding wires of different diameters, thus having a wide range of applications; at the same time, it avoids copper layer peeling and damage to the inside of the grounding wire.

[0005] To achieve the above objectives, the specific solution adopted by this utility model is as follows: a straightening device for copper-clad steel grounding wires includes a mounting plate and a support frame for supporting the mounting plate. A set of straightening rollers for pressing the grounding wire is rotatably arranged on the mounting plate. A primary straightening zone is formed between two straightening rollers, allowing the grounding wire to pass through. One of the straightening rollers is driven to rotate by a drive source. A first sliding plate that can slide perpendicular to the direction of movement of the grounding wire is provided on the mounting plate. Another straightening roller is rotatably connected to the first sliding plate. A first push rod for pushing the first sliding plate toward the primary straightening zone is provided on the side of the first sliding plate away from the primary straightening zone. Multiple auxiliary rollers are provided on the side of the straightening roller away from the grounding wire, and the multiple auxiliary rollers are respectively located on both sides of the grounding wire, so that a secondary straightening zone is formed between the auxiliary rollers on both sides of the grounding wire, allowing the grounding wire to pass through. Multiple second sliding plates that can slide perpendicular to the direction of movement of the grounding wire are provided on the mounting plate, and the second sliding plates are located on the same side as the first sliding plates. An auxiliary roller located on this side is rotatably connected to the corresponding second sliding plate. A second push rod for pushing the second sliding plate toward the secondary straightening zone is provided on the side of the second sliding plate away from the secondary straightening zone.

[0006] As an optimized solution for the above-mentioned straightening device for copper-clad steel grounding wire: the mounting plate is provided with a heating component for heating the grounding wire. The heating component is located on the side where the straightening roller enters the grounding wire. The heating component includes an electromagnetic heating coil and a power supply for supplying power to the electromagnetic heating coil. After the grounding wire is heated by passing through the electromagnetic heating coil, it passes through the primary straightening zone and the secondary straightening zone in sequence.

[0007] As another optimized solution for the above-mentioned straightening device for copper-clad steel grounding wire: the mounting plate is provided with heat insulation covers corresponding to all straightening rollers and all auxiliary rollers. The heat insulation covers and the mounting plate form a heat insulation cavity with one end open for accommodating the straightening rollers or auxiliary rollers. The openings of the heat insulation cavities all face the corresponding primary straightening area and secondary straightening area, and some straightening rollers and some auxiliary rollers extend out of the corresponding heat insulation cavities.

[0008] As an alternative optimization of the above-mentioned straightening device for copper-clad steel grounding wire: the heat insulation cover includes a reflective layer and a heat insulation layer arranged sequentially from the inside to the outside.

[0009] As another optimized solution for the straightening device for the copper-clad steel grounding wire mentioned above: the first push rod is a threaded rod, and a first threaded sleeve fixedly connected to the mounting plate is sleeved on its outside. During the rotation of the first push rod, the first sliding plate is pushed to slide.

[0010] As another optimized solution for the straightening device for the copper-clad steel grounding wire mentioned above: the edge of the mounting plate is fixedly connected to a first mounting block, and the outer wall of the first threaded sleeve is fixedly connected to the first mounting block.

[0011] As an alternative optimization of the above-mentioned straightening device for copper-clad steel grounding wire: a first push rod is vertically fixedly connected to the first slide plate, and the top end of the first push rod can abut against the first push rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model provides a straightening device for copper-clad steel grounding wires. The first and second sliding plates drive the straightening roller and auxiliary roller to slide, thereby adjusting the width of the primary straightening zone and the secondary straightening zone, thus making it suitable for grounding wires of different diameters. At the same time, by adjusting the width of the primary straightening zone and the secondary straightening zone, the squeezing force of the straightening roller on the grounding wire can be adjusted, avoiding the copper layer peeling or internal structure damage caused by insufficient straightening or over-straightening of the grounding wire.

[0017] 2. In this utility model, after the grounding wire is heated by the heating component, it is straightened by passing through the first straightening zone and the second straightening zone in sequence. Heating the grounding wire before straightening can eliminate some of the residual stress caused by winding and improve the final straightness of the grounding wire; at the same time, it reduces damage to the copper layer, thereby ensuring the good conductivity of the grounding wire; the surface of the grounding wire after straightening is smooth, reducing impurities and defects on the surface of the copper layer, reducing corrosion caused by surface roughness, and further improving the stability of the grounding wire.

[0018] 3. In this utility model, in order to slow down the cooling rate of the grounding wire, a heat insulation cover is provided on the straightening roller and the auxiliary roller. When the straightening roller and the auxiliary roller are grounded after straightening and heating, heat conduction will occur, that is, the temperature of the straightening roller and the auxiliary roller will increase. The setting of the heat insulation cover prevents the heat from spreading from the parts of the straightening roller and the auxiliary roller that are not in contact with the grounding wire, thereby ensuring that the straightening roller and the auxiliary roller have a certain temperature, which not only facilitates the straightening of the grounding wire, but also prevents the copper layer from peeling off due to rapid cooling.

Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as how the power supply is connected to the electromagnetic heating coil 301, how the heating component 3 controls the heating temperature of the grounding wire 2, the material of the reflective layer 1101, and the material of the heat insulation layer 1102.

[0025] Example 1

[0026] A straightening device for copper-clad steel grounding wires, such as Figure 1 As shown, it includes a mounting plate 1 and a support frame 101 for supporting the mounting plate 1. The mounting plate 1 is a rectangular plate structure. The support frame 101 is formed by connecting 8 support rods. Specifically, four support rods are connected end to end to form a rectangular frame. The rectangular frame is located below the mounting plate 1. The remaining four support rods are vertically fixed at the four corners of the rectangular frame. The connection between the support rods is welded. The top ends of the four support rods are fixedly connected to the lower surface of the mounting plate 1. In this embodiment, the connection between the ends of the support rods and the lower surface of the mounting plate 1 is welded.

[0027] like Figure 2 As shown, a set of straightening rollers 4 for pressing the grounding wire 2 is rotatably mounted on the mounting plate 1. That is, there are two straightening rollers 4, and a primary straightening zone is formed between the two straightening rollers 4, through which the grounding wire 2 can pass. One of the straightening rollers 4 is driven to rotate by a drive source. In this embodiment, the drive source is a drive motor 6 fixed on the mounting plate 1, which drives the straightening roller 4 located above. Specifically, a rotating shaft is rotatably mounted on the mounting plate 1. One end of the rotating shaft extends into the lower part of the mounting plate 1 and is fixedly connected to the motor shaft of the drive motor 6 below the mounting plate 1. The straightening roller 4 is coaxially fixedly sleeved on the rotating shaft, so that the drive motor 6 drives the rotating shaft to rotate, and drives the straightening roller 4 to rotate, so that the grounding wire 2 passes through the primary straightening zone and is straightened.

[0028] The mounting plate 1 is equipped with a first sliding plate 401 that can slide along a direction perpendicular to the grounding wire 2. The first sliding plate 401 is a rectangular plate structure. Another straightening roller 4 is rotatably connected to the first sliding plate 401. Figure 1As shown, the first slide plate 401 can move up and down, and the straightening roller 4 located below it is rotatably mounted on the first slide plate 401. Specifically, the first slide plate 401 is vertically fixedly connected to a fixed shaft, and a first connecting piece 402 is fixedly connected to one end of the fixed shaft away from the first slide plate 401. The straightening roller 4 is rotatably sleeved on the fixed shaft, so that the straightening roller 4 can move synchronously with the first slide plate 401. In this embodiment, the first slide plate 401 is configured such that a first sliding hole 103 is provided on the mounting plate 1. The first sliding hole 103 is a rectangular hole, and slide rails are provided on both edges of the first sliding hole 103. The first slide plate 401 cooperates with the slide rails.

[0029] A first push rod 7 is provided on the side of the first slide plate 401 away from the primary straightening area to push it towards the primary straightening area. In this embodiment, the first push rod 7 is a threaded rod, and a first threaded sleeve 8 fixedly connected to the mounting plate 1 is sleeved on its outside. The first threaded sleeve 8 is threadedly connected to the threaded rod, and the first push rod 7 pushes the first slide plate 401 to slide during rotation. The first threaded sleeve 8 is connected to the mounting plate 1 in the following way: a first mounting block 104 is fixedly connected to the edge of the mounting plate 1, and the outer wall of the first threaded sleeve 8 is fixedly connected to the first mounting block 104. A handle is connected to the first push rod 7 to facilitate rotation of the first push rod 7.

[0030] In this embodiment, a first push rod 403 is vertically fixedly connected to the first slide plate 401. The first push rod 403 is located on the side of the straightening roller 4 away from the primary straightening area. One end of the first push rod 403 is fixedly connected to the first slide plate 401, and the other end of the first push rod 403 is fixedly connected to the first connecting piece 402. The top end of the first top rod 7 can abut against the outer wall of the first push rod 403.

[0031] like Figure 2 As shown, when it is necessary to reduce the width of the primary straightening zone, the first push rod 7 is rotated. The first push rod 7 pushes the first push rod 403 to move the first slide plate 401 upward to the required position. When adjusting the ground wire 2, the first push rod 7 presses against the first push rod 403 to prevent the ground wire 2 from entering the primary straightening zone and pushing the first slide plate 401 downward, thus ensuring the squeezing force of the two straightening rollers 4 on the ground wire 2.

[0032] Multiple auxiliary rollers 5 are arranged on the side of the straightening roller 4 away from the grounding wire 2. These auxiliary rollers 5 are located on both sides of the grounding wire 2, forming a secondary straightening zone between the auxiliary rollers 5 on both sides of the grounding wire 2, through which the grounding wire 2 can pass. In this embodiment, there are five auxiliary rollers 5, with three located at the top and two at the bottom, and the five auxiliary rollers 5 are staggered. Figure 2As shown. The three upper auxiliary rollers 5 are rotatably connected to the mounting plate 1. The two lower auxiliary rollers 5 are mounted on the mounting plate 1 with multiple second sliding plates 501 that can slide along a direction perpendicular to the grounding wire 2. There are two second sliding plates 501, and the second sliding plates 501 are located on the same side as the first sliding plate 401. The auxiliary rollers 5 on this side are rotatably connected to the corresponding second sliding plates 501, so that the auxiliary rollers 5 and the second sliding plates 501 correspond one-to-one. The second sliding plate 501 is a rectangular plate structure, and the auxiliary rollers 5 are rotatably connected to the second sliding plates 501, as shown. Figure 1 As shown, the second slide plate 501 can move up and down. The first slide plate 401 is vertically fixedly connected to a mounting shaft. A second connecting piece 502 is fixedly connected to one end of the mounting shaft away from the second slide plate 501. The auxiliary roller 5 is rotatably sleeved on the mounting shaft, so that the auxiliary roller 5 can move synchronously with the second slide plate 501. In this embodiment, the second slide plate 501 is configured such that the mounting plate 1 has a second sliding hole 102 corresponding to the second slide plate 501. The second sliding hole 102 is a rectangular hole, and slide rails are provided on the two edges of the second sliding hole 102. The second slide plate 501 cooperates with the slide rails.

[0033] A second push rod 9 is provided on the side of the second slide plate 501 away from the secondary straightening area to push it towards the secondary straightening area. In this embodiment, the second push rod 9 is a threaded rod, and a second threaded sleeve 10 fixedly connected to the mounting plate 1 is sleeved on its outside. The second threaded sleeve 10 is threadedly connected to the threaded rod, and the second push rod 9 pushes the second slide plate 501 to slide during rotation. The second threaded sleeve 10 is connected to the mounting plate 1 in such a way that a second mounting block 105 is fixedly connected to the edge of the mounting plate 1, and the outer wall of the second threaded sleeve 10 is fixedly connected to the second mounting block 105. A handle is connected to the second push rod 9 to facilitate rotation of the second push rod 9.

[0034] In this embodiment, a second push rod 503 is vertically fixedly connected to the second slide plate 501. The second push rod 503 is located on the side of the auxiliary roller 5 away from the secondary straightening area. One end of the second push rod 503 is fixedly connected to the second slide plate 501, and the other end of the second push rod 503 is fixedly connected to the second connecting piece 502. The top end of the second top rod 9 can abut against the outer wall of the second push rod 503.

[0035] like Figure 2As shown, when it is necessary to reduce the width of the secondary straightening zone, the second push rod 9 is rotated. The second push rod 9 pushes the second push rod 503, causing the second slide plate 501 to move upward to the desired position. When adjusting the ground wire 2, the second push rod 9 presses against the second push rod 503 to prevent the ground wire 2 from entering the secondary straightening zone and pushing the second slide plate 501 downward, thus ensuring the squeezing force of the auxiliary roller 5 on the ground wire 2. By adjusting the width of the primary and secondary straightening zones, the squeezing force of the straightening roller 4 and the auxiliary roller 5 on the ground wire 2 can be adjusted, preventing the copper layer from peeling off or the internal structure from being damaged due to insufficient or excessive straightening of the ground wire 2.

[0036] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0037] Example 2

[0038] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 3 As shown, a heating assembly 3 for heating the grounding wire 2 is provided on the mounting plate 1. The heating assembly 3 is located on the side where the straightening roller 4 enters the grounding wire 2. The heating assembly 3 includes an electromagnetic heating coil 301 and a power supply for powering the electromagnetic heating coil 301. A housing 302 is fixedly connected to the mounting plate 1. The electromagnetic heating coil 301 is located inside the housing 302. Passing holes for the grounding wire 2 to pass through are opened on both sides of the housing 302. After being heated by the electromagnetic heating coil 301, the grounding wire 2 passes through the primary straightening zone and the secondary straightening zone in sequence. Heating the grounding wire 2 before straightening can eliminate some of the residual stress caused by winding, improving the final straightness of the grounding wire 2; at the same time, it reduces damage to the copper layer, thus ensuring good conductivity of the grounding wire 2; the surface of the grounding wire after straightening is smooth, reducing impurities and defects on the copper layer surface, reducing corrosion caused by surface roughness, and further improving the stability of the grounding wire 2.

[0039] The mounting plate 1 is provided with heat insulation covers 11 corresponding to all straightening rollers 4 and all auxiliary rollers 5. A heat insulation cavity with one open end is formed between the heat insulation cover 11 and the mounting plate 1 to accommodate the straightening roller 4 or auxiliary roller 5. The openings of the heat insulation cavities all face the corresponding primary straightening area and secondary straightening area, and some straightening rollers 4 and some auxiliary rollers 5 extend out of the corresponding heat insulation cavities. In this embodiment, as shown... Figure 3 As shown, the upper heat insulation cover 11 is connected to the mounting plate 1, and the lower heat insulation cover 11 is connected to the corresponding first sliding plate 401 and second sliding plate 501.

[0040] like Figure 4As shown, the heat insulation cover 11 includes a reflective layer 1101 and a heat insulation layer 1102 arranged sequentially from the inside to the outside. The reflective layer 1101 can reflect heat into the heat insulation cavity, further improving the heat insulation effect of the heat insulation cover 11. In order to slow down the cooling rate of the grounding wire 2, the heat insulation cover 11 is provided on the straightening roller 4 and the auxiliary roller 5. When the straightening roller 4 and the auxiliary roller 5 are straightened and heated, heat conduction will occur, that is, the temperature of the straightening roller 4 and the auxiliary roller 5 will increase. The setting of the heat insulation cover 11 avoids the heat diffusion of the parts of the straightening roller 4 and the auxiliary roller 5 that are not in contact with the grounding wire 2, thereby ensuring that the straightening roller 4 and the auxiliary roller 5 have a certain temperature, which not only facilitates the straightening of the grounding wire 2, but also avoids the copper layer peeling off due to rapid cooling.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
