Description

Technical Field

[0001] This utility model relates to the field of stranded wire technology, and in particular to a pull-head stabilizing device and stranding equipment for dividing conductor strands. Background Technology

[0002] As power transmission evolves towards higher capacity, large-section conductors are increasingly used. However, due to the AC skin effect, when the conductor diameter increases to a certain extent, the AC resistance of the conductor becomes significantly greater than its DC resistance. Therefore, simply increasing the cross-sectional area becomes impractical and uneconomical. To effectively reduce the AC resistance of the conductor, a segmented conductor structure can be used. A segmented conductor is composed of multiple sector-shaped strands twisted together. Segmentation reduces the skin effect between conductors, thereby lowering the AC resistance and increasing the current-carrying capacity of the cable.

[0003] In the production of split conductors, split conductor strands are first made on a stranding machine, and then these strands are assembled on a cabling machine. The split conductor consists of multiple layers of conductors arranged sequentially from the inside out. During the production of the split conductor strands, the first section is pulled, which involves creating the first segment of the strand. During this pulling process, the production line frequently stops and starts, making it difficult to achieve the required strand pitch. Therefore, this section of the strand pulled does not proceed to the next process. During the pulling process, the conductor end is first passed through multiple coils and connected to a traction device. The traction device then pulls the conductor forward, sequentially opening each coil along the direction of conductor movement. Each coil includes a stranding mechanism and a pressure roller device. Each stranding mechanism strands one layer of conductor. Simultaneously, the stranding mechanism also uses the pressure roller device to compress the stranded wire bundle. The pressure roller device consists of two pressure rollers, essentially a set of molds, pressing the cross-section of the stranded wire bundle into a fan shape. Because the winch rotates the stranded wire bundle during the winding process, the fan-shaped stranded wire bundle rotates as it passes between the two pressure rollers of the next winch. Since the fan-shaped stranded wire bundle is constantly rotating, its posture is constantly changing, making it difficult to match the shape of the two pressure rollers it passes through. Therefore, operators need to keep the machine running until the posture of the fan-shaped stranded wire bundle matches the shape of the two pressure rollers before they can control the subsequent pressure rollers to press the fan-shaped stranded wire bundle tightly. This results in a large amount of copper material being scrapped. Taking a 2500mm² segmented strand block as an example, in the existing technology, approximately 120 meters of product need to be scrapped during the winding process. The existing technology urgently needs improvement to address these problems. Utility Model Content

The second contoured guide wheel is rotatably connected to the second guide wheel support and has a... The second groove is used to embed the fan-shaped stranded wire harness. The driving device is used to drive the first and second contour guide wheels to move closer and further apart. When the first and second contour guide wheels move closer together, their rotation axes are parallel and located on both sides of the fan-shaped stranded wire harness. The first and second grooves guide the fan-shaped stranded wire harness to move forward and restrict its rotation. When the first and second contour guide wheels move further apart, the first and second grooves allow the fan-shaped stranded wire harness to move forward and rotate.

[0006] Furthermore, the first groove is a V-shaped groove with a V-shaped surface on its inner wall, which is used to contact the V-shaped surface of the fan-shaped stranded wire bundle; the second groove is an arc-shaped groove with an arc-shaped surface on its inner wall, which is used to contact the arc-shaped surface of the fan-shaped stranded wire bundle.

The first contouring guide wheel is installed at one end of the first swing arm, and the second contouring guide wheel is installed at one end of the second swing arm.

[0008] Furthermore, the guide wheel assembly also includes a connecting rod and a connecting plate.

[0012] Furthermore, the driving device is a cylinder.

[0016] Multiple pressure roller devices are respectively located on the wire harness output side of the multiple stranding devices, used to press the cross-section of the stranded wire harness formed by stranding into a fan shape and guide the fan-shaped stranded wire harness to move and rotate with the fan-shaped stranded wire harness;

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0033] In existing technologies, large-section conductors often employ a segmented conductor structure to reduce AC resistance. The fabrication of segmented conductor strands requires a pulling process. In traditional processes, the rotation of the stranded wire harness makes it difficult to match its orientation with the shape of the subsequent pressing roller, requiring operators to repeatedly adjust the equipment to complete the pressing, resulting in a large amount of copper material being scrapped. This severely impacts production economics. Therefore, this invention proposes a pulling head stabilization device for segmented conductor strands.

[0034] See Figure 1 The image shows an embodiment of the pull-head stabilizing device for segmented conductor strands provided by this utility model.

[0035] The pull head stabilizing device includes a bracket assembly 1 and a guide wheel assembly 2. The bracket assembly 1 includes a base 11, and the guide wheel assembly 2 is mounted on the bracket assembly 1. The guide wheel assembly 2 includes a first guide wheel bracket 21, a first contouring guide wheel 22, a second guide wheel bracket 23, a second contouring guide wheel 24, and a driving device 25. The first contouring guide wheel 22 is rotatably connected to the first guide wheel bracket 21 and has a first groove 221 for embedding a fan-shaped stranded wire harness A. The second contouring guide wheel 24 is rotatably connected to the second guide wheel bracket 23 and has a second groove for embedding a fan-shaped stranded wire harness A. 241. The aforementioned driving device 25 is used to drive the first contouring guide wheel 22 and the second contouring guide wheel 24 to move closer and further apart. When the first contouring guide wheel 22 and the second contouring guide wheel 24 move closer together, their rotation axes are parallel and located on both sides of the fan-shaped stranded wire harness A. The first wheel groove 221 and the second wheel groove 241 guide the fan-shaped stranded wire harness A to move forward and restrict its rotation. When the first contouring guide wheel 22 and the second contouring guide wheel 24 move further apart, the first wheel groove 221 and the second wheel groove 241 allow the fan-shaped stranded wire harness A to move forward and rotate.

[0036] In the above text, bracket assembly 1 refers to the rigid support structure that supports guide wheel assembly 2, ensuring that guide wheel assembly 2 maintains stable positioning during operation. The first guide wheel bracket 21 and the second guide wheel bracket 23 in guide wheel assembly 2 constitute a movable support structure, providing displacement freedom for the first contouring guide wheel 22 and the second contouring guide wheel 24. The drive device 25 drives the first guide wheel bracket 21 and the second guide wheel bracket 23 to move towards each other, thereby achieving precise control of the relative positional relationship between the first contouring guide wheel 22 and the second contouring guide wheel 24.

[0037] Specifically, when the conductor strands are being pulled together, and the fan-shaped stranded wire harness A requires orientation positioning, the drive device 25 pushes the first contouring guide wheel 22 and the second contouring guide wheel 24 closer to a preset position. At this time, the first groove 221 and the second groove 241 respectively fit against the two side surfaces of the fan-shaped stranded wire harness A. The geometric fit between the contours of the first groove 221 and the second groove 241 and the shape of the fan-shaped stranded wire harness A restricts the circumferential rotation of the fan-shaped stranded wire harness A, while allowing the fan-shaped stranded wire harness A to continue moving along the axial direction. After the conductor strands are pulled together, the drive device 25 drives the first contouring guide wheel 22 and the second contouring guide wheel 24 to separate.

[0038] Through the above technical solution, this utility model can perform attitude positioning of the moving fan-shaped stranded wire bundle A during the pulling process of splitting conductor strands, ensuring that the fan-shaped stranded wire bundle A enters the next pressure roller in the correct attitude. This not only significantly reduces the frequency of manual intervention, but also reduces material scrap caused by attitude misalignment, reducing the copper scrap rate of the strand pulling head by about 40%, and significantly improving the pass rate of the pulling head process.

[0039] In this embodiment, the first groove 221 is a V-shaped groove with a V-shaped surface on its inner wall, which is used to contact the V-shaped surface of the fan-shaped stranded wire harness A. The second groove 241 is an arc-shaped groove with an arc-shaped surface on its inner wall, which is used to contact the arc-shaped surface of the fan-shaped stranded wire harness A.

[0040] In the above text, a V-groove refers to a structure with two inclined sidewalls forming an included angle. The V-shaped surface can form surface contact with the V-shaped surface of the fan-shaped stranded wire bundle A, and the clamping effect of the two inclined surfaces restricts the circumferential rotation of the fan-shaped stranded wire bundle A. An arc-shaped groove refers to a structure with a concave arc surface. The arc surface can cover the arc-shaped area of ​​the fan-shaped stranded wire bundle A, maintaining the radial constraint of the fan-shaped stranded wire bundle A while allowing axial movement.

[0041] Specifically, when the fan-shaped stranded wire bundle A enters between the first contouring guide wheel 22 and the second contouring guide wheel 24, the V-shaped surface of the fan-shaped stranded wire bundle A is clamped by the inclined sidewall of the V-shaped groove. The geometric constraint of the inclined surfaces on both sides prevents the fan-shaped stranded wire bundle A from rotating around its own axis. At the same time, the arc-shaped surface of the fan-shaped stranded wire bundle A is fitted by the concave surface of the arc-shaped groove. The friction and covering effect generated by the contact of the arc surfaces further suppress the circumferential displacement of the fan-shaped stranded wire bundle A. The complementary cooperation of the two groove structures ensures that different cross-sectional areas of the fan-shaped stranded wire bundle A are constrained by the corresponding shape during its movement. The rotational degree of freedom is eliminated through geometric locking, ensuring that the fan-shaped stranded wire bundle A always maintains a stable posture.

[0042] This invention enables the fan-shaped stranded wire harness A to maintain a stable posture during its movement by interlocking the first groove 221 and the second groove 241 with the cross-section of the fan-shaped stranded wire harness A.

[0043] In this embodiment, the first guide wheel bracket 21 is a first swing arm, and the second guide wheel bracket 23 is a second swing arm. Both the first swing arm and the second swing arm can be oscillatingly connected to the bracket assembly 1. The swing axes of the first swing arm and the second swing arm are parallel to the rotation axes of the first contouring guide wheel 22 and the second contouring guide wheel 24. The first contouring guide wheel 22 is installed at one end of the first swing arm, and the second contouring guide wheel 24 is installed at one end of the second swing arm.

[0044] In the above text, the first and second swing arms refer to rod-shaped structures with a pivot point, which can be implemented by hinge connection or bearing support. The spatial positions of the first and second contour guide wheels 22 and 24 are changed by rotating around the swing axis. The first contour guide wheel 22 being installed at one end of the first swing arm means that the first contour guide wheel 22 is positioned at the end of the first swing arm away from the swing axis. The second contour guide wheel 24 being installed at one end of the second swing arm means that the second contour guide wheel 24 is positioned at the end of the second swing arm away from the swing axis. The lever effect of the swing arms amplifies the adjustment stroke of the drive device 25.

[0045] Specifically, the first and second swing arms move in opposite directions to bring the first and second contour guide wheels 22 and 24 closer together and further apart. When the first and second swing arms swing inward, the first and second contour guide wheels 22 and 24 clamp the fan-shaped stranded wire bundle A, restricting its rotational freedom. When the first and second swing arms swing outward, the first and second contour guide wheels 22 and 24 disengage from their constrained positions, allowing the fan-shaped stranded wire bundle A to rotate freely.

[0046] This invention uses a swinging motion to achieve the mutual approach and distance between the first contour guide wheel 22 and the second contour guide wheel 24, resulting in a relatively compact structure.

[0047] In this embodiment, the guide wheel assembly 2 further includes a connecting rod 26 and a connecting plate 27. The other end of the first swing arm and the other end of the second swing arm are respectively connected to the same connecting plate 27 through the connecting rod 26. The driving device drives the connecting plate 27 to move along the travel direction of the fan-shaped twisted wire harness A.

[0048] In the above text, link 26 refers to the rod-shaped component that rigidly connects the swing arm and the connecting plate 27. Specifically, it can be implemented using a combination of metal rods and a hinged structure, used to convert the linear motion of the connecting plate 27 into the swinging motion of the first and second swing arms. The connecting plate 27 synchronously receives the linear driving force from the drive device 25 and transmits it to the two links 26. Movement along the direction of travel means that the direction of force applied by the drive device 25 is parallel to the trajectory of the fan-shaped stranded wire harness A being pulled along.

[0049] Specifically, when the drive device 25 pushes the connecting plate 27 to move linearly along the direction of travel, the two connecting rods 26 respectively convert the displacement of the connecting plate 27 into symmetrical swinging of the first and second swing arms around a fixed axis. Since the first and second swing arms are linked through the same connecting plate 27, their swing angles and speeds are strictly synchronized, ensuring that the opening and closing actions of the first and second contouring guide wheels 22 and 24 are always symmetrical. The linear motion path of the connecting plate 27 is consistent with the direction of travel of the fan-shaped stranded wire harness A, so that the guide wheel assembly 2 moves in tandem along the direction of travel during the swinging of the first and second swing arms, avoiding instability of the fan-shaped stranded wire harness A due to lateral displacement caused by the swinging.

[0050] This invention, through the connecting rod 26 and the connecting plate 27, ensures that the fan-shaped stranded wire harness A is always subjected to symmetrical and balanced clamping force during its movement, so that the fan-shaped stranded wire harness A can stably pass through the guide space formed by the first contour guide wheel 22 and the second contour guide wheel 24.

[0051] In this embodiment, the connecting plate 27 is provided with a connecting plate through hole 271 for the fan-shaped twisted wire harness A to pass through.

[0052] In the above text, the connecting plate through hole 271 refers to the through hole structure opened in the connecting plate 27, which should be larger than the cross-section of the fan-shaped stranded wire harness A. The inner wall of the connecting plate through hole 271 maintains a non-contact gap with the outer surface of the fan-shaped stranded wire harness A, allowing the fan-shaped stranded wire harness A to move freely within the connecting plate through hole 271.

[0053] Specifically, when the drive device 25 drives the connecting plate 27 to move along the direction of travel, the sector-shaped twisted wire harness A continuously passes through the connecting plate through hole 271. During the reciprocating motion of the connecting plate 27, its connecting plate through hole 271 always maintains a spatial avoidance relationship with the sector-shaped twisted wire harness A.

[0054] This utility model effectively solves the structural interference problem between the drive device 25 and the fan-shaped twisted wire harness A when the drive device 25 drives the connecting plate 27 to move by setting the connecting plate through hole 271.

[0055] In this embodiment, the bracket assembly 1 further includes a swing arm fixing plate 12, which is connected to the base 11, and the first swing arm and the second swing arm are connected to the swing arm fixing plate 12.

[0056] In the above text, the swing arm fixing plate 12 refers to a rigid support structure that provides a unified installation reference for the first and second swing arms. This structure ensures that the swing axes of the first and second swing arms remain parallel by restricting the degrees of freedom of the swing base points of the first and second swing arms.

[0057] Specifically, the swing arm fixing plate 12 serves as a rigid mounting platform, integrating the originally separate first and second swing arms onto the same base.

[0058] This utility model makes it easier to connect the first swing arm and the second swing arm by setting the swing arm fixing plate 12.

[0059] In this embodiment, the aforementioned swing arm fixing plate 12 is provided with a fixing plate through hole 121 for the fan-shaped twisted wire harness A to pass through.

[0060] In the above text, the swing arm fixing plate 12 refers to the plate-like structure that supports the first and second swing arms, and is used to provide a unified installation reference for the first and second swing arms. The fixing plate through hole 121 refers to the hole-like structure that passes through the swing arm fixing plate 12, and its hole diameter can be adjusted according to the cross-section of the fan-shaped stranded wire harness A, so as to provide an unobstructed passage for the moving fan-shaped stranded wire harness A.

[0061] Specifically, the first and second swing arms are connected at symmetrical positions on the same swing arm fixing plate 12 via pins or shafts, and their swing axes remain parallel. When the drive device 25 drives the connecting plate 27 to move, the first and second swing arms swing synchronously based on the constraints of the swing arm fixing plate 12.

[0062] This utility model avoids the physical obstruction of the fan-shaped twisted wire harness A by setting a through hole 121 in the fixing plate.

[0063] In this embodiment, the driving device 25 is a cylinder.

[0064] In the above text, the cylinder refers to the actuator that converts the energy of compressed gas into linear reciprocating mechanical energy. By utilizing the linear motion characteristics of the cylinder, the connecting plate 27 can be directly driven to move in a preset direction without the need for a complex transmission mechanism. This reduces the response delay and error accumulation in the power transmission process, and ensures the synchronicity and stability of the guide wheel position adjustment.

[0065] Specifically, the piston rod end of the cylinder is fixedly connected to the connecting plate 27. When the cylinder receives a control signal, the piston rod moves linearly along the direction of travel of the fan-shaped twisted wire harness A, causing the connecting plate 27 to move synchronously. The connecting plate 27 converts the linear motion into the swinging motion of the first swing arm and the second swing arm through the connecting rod 26, causing the first contouring guide wheel 22 and the second contouring guide wheel 24 to move closer to or further away from each other.

[0066] This invention uses a cylinder to ensure that the guide wheel assembly 2 effectively limits or quickly releases the fan-shaped stranded wire harness A through the cylinder's rapid response and high-precision linear motion control.

[0067] In this embodiment, the bracket assembly 1 further includes a cylinder fixing plate 13, which is connected to the base 11 and the cylinder is mounted on the cylinder fixing plate 13.

[0068] In the above text, the cylinder mounting plate 13 refers to a plate-like structure that provides rigid mounting support for the cylinder, and its function is to eliminate the vibration transmission path during cylinder operation. The cylinder being mounted on the cylinder mounting plate 13 means that the cylinder base is rigidly connected to the mounting plate via fasteners.

[0069] This utility model facilitates flexible installation of the cylinder by setting a cylinder fixing plate 13.

[0070] See Figure 2 The present invention discloses an embodiment of a stranding device for dividing conductor strands.

[0071] Stranding equipment includes:

[0072] Multiple stranding devices B are arranged at intervals along the X-axis direction, and the stranding devices B are used to strand wires;

[0073] Multiple pressure roller devices C are respectively located on the wire harness output side of the multiple stranding devices B, and are used to press the cross-section of the stranded wire harness formed by stranding into a fan shape and guide the fan-shaped stranded wire harness A to move and rotate with the fan-shaped stranded wire harness A.

[0074] Multiple pull head stabilizing devices D are provided between the wire harness output side of the pressure roller device C and the wire harness input side of the stranding device B. The rotation axes of the first contouring guide wheel 22 and the second contouring guide wheel 24 both extend along the Y-axis direction.

[0075] In the above text, the stranding device B can strand multiple strands of wire into a composite wire bundle through rotational motion, and the pressure roller device C can constrain the cross-sectional shape of the wire bundle. The pressure roller device C refers to an assembly containing two pressure rollers arranged opposite each other, and the shape of the pressure roller cavity matches the cross-section of the target fan-shaped stranded wire bundle A. The pull-head stabilizing device D prevents the wire bundle from shifting its attitude by constraining its circumferential degrees of freedom.

[0076] Specifically, when the wire harness enters the transition area between the output side of the adjacent stranding device B and the input side of the pressure roller device C, the pull-head stabilizing device D inhibits the circumferential rotation of the fan-shaped stranded wire harness A through physical contact. This rotation inhibition keeps the fan-shaped stranded wire harness A in a fixed posture before entering the next pressure roller device C, ensuring that the fan-shaped stranded wire harness A is perfectly matched with the pressure roller cavity of the next pressure roller device C. After the pull-head process, all pressure roller devices C have clamped the wire harness in the correct posture. At this time, the pull-head stabilizing device D releases the fan-shaped stranded wire harness A, and the stranding device B and pressure roller device C work together to achieve the stranding and pressing of the divided conductor strands.

[0077] This invention effectively solves the problem of difficulty in matching pressure rollers caused by the rotation of stranded wire harnesses, avoids material waste caused by manual adjustment, and realizes continuous and automatic production of the stranding process of segmented conductor blocks.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
