Description

Technical Field

[0001] This utility model belongs to the technical field of stress relief devices, and in particular relates to a stress relief device for aluminum alloy stranded wire. Background Technology

[0002] Aluminum alloy stranded wire stress relief devices are key auxiliary components for overhead transmission lines. They are designed to alleviate axial stress in stranded wires caused by temperature changes, wind loads, etc., and to prevent damage caused by excessive stretching or loosening of the wire. Through a special structural design, they absorb stress using elastic components or sliding mechanisms, allowing the stranded wire to freely expand and contract within a certain range while maintaining connection stability. Made of high-strength aluminum alloy, they are both lightweight and corrosion-resistant, adaptable to different specifications of stranded wires, and easy to install. They can effectively improve the safety and service life of the line and are widely used in high-voltage transmission projects.

[0003] According to a public disclosure (Publication No.: CN212587256U), an aluminum alloy stranded wire stress relief device includes: a bracket, a first repair wheel rotatably connected to the bracket, a set of spring clamping devices installed at each end of the bracket, and several screw clamping devices provided on the bracket. The screw clamping devices are arranged between two sets of spring clamping devices. Each spring clamping device includes a second screw, a spring frame, a smooth rod, a third repair wheel frame, and a third repair wheel. The second screw is installed on the bracket, a spring frame is installed at one end of the second screw, a smooth rod is provided on the spring frame, a third repair wheel frame is provided on the smooth rod, a third repair wheel is rotatably connected to the third repair wheel frame, and a first spring is provided between the third repair wheel frame and the spring frame.

[0004] In the aforementioned application, stress relief of aluminum alloy stranded wire was achieved through the cooperation of components such as spring frame and screw clamping device. However, the stress relief effect was not good, resulting in the aluminum alloy stranded wire failing to meet the process requirements. Therefore, we propose an aluminum alloy stranded wire stress relief device. Utility Model Content

[0005] The purpose of this invention is to provide a stress relief device for aluminum alloy stranded wire. Through the design of components such as a rolling mechanism and a vibration mechanism, it solves the problem that the stress relief effect in the prior art is not good, which leads to the aluminum alloy stranded wire failing to meet the process requirements.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an aluminum alloy stranded wire stress relief device, including a body, a support foot pad fixedly connected to the bottom of the body, a support plate one fixedly connected to the side of the body, a motor one fixedly connected to the side of the support plate one, a wire coil fixedly connected to the end of the output shaft of the motor one, a support plate two fixedly connected to the side of the body, a motor two fixedly connected to the side of the support plate two, a storage coil fixedly connected to the end of the output shaft of the motor two, and a roller pressing mechanism provided inside the body; The roller pressing mechanism includes a vertical plate, the bottom of which is fixedly connected to the inner side of the machine body. A motor three is fixedly connected to the side of the vertical plate. A rotating shaft one is fixedly connected to the end of the output shaft of the motor three. A roller one is fixedly connected to the circumferential surface of the rotating shaft one. A gear one is fixedly connected to one end of the rotating shaft one. A rotating shaft two is rotatably connected to the side of the vertical plate. A roller two is fixedly connected to the circumferential surface of the rotating shaft two. A gear two is fixedly connected to one end of the rotating shaft two. The gear one and gear two mesh with each other.

[0007] Furthermore, the number of supporting feet is set to several and arranged in a linear array at the bottom of the machine body, which can increase the force-bearing area between the machine body and the contact surface, making the overall force of the device more uniform, effectively enhancing the placement stability, and avoiding displacement or shaking caused by vibration during operation. The number of support plates one and two is set to two, and they are symmetrical to each other along the vertical central axis of the coil, which can balance the weight of the load-bearing components, ensure their coaxiality and stability during operation, and improve the reliability and service life of the device.

[0008] Furthermore, spokes are provided on the sides of gear one and gear two. The number of spokes is set to a certain number and arranged in a circumferential array on the sides of gear one and gear two. This reduces the weight of the gears while ensuring the structural strength of the gears, and reduces energy consumption and inertia during rotation. The number of teeth of gear one is equal to the number of teeth of gear two, which can ensure that the rotation speed is the same and the direction of rotation is opposite during meshing transmission.

[0009] Furthermore, the number of rollers one is set to several and arranged in a linear array on the circumference of the rotating shaft one, and the number of rollers two is set to several and arranged in a linear array on the circumference of the rotating shaft two. This can form multiple sets of rolling pressure on the aluminum alloy stranded wire, improve the overall stress release efficiency, and ensure the stability of the stranded wire performance.

[0010] Furthermore, the machine body is equipped with a vibration mechanism, which includes a support frame. The bottom of the support frame is fixedly connected to the inner side of the machine body. A rotating rod is rotatably connected to the inner side of the support frame. One end of the rotating rod is fixedly connected to a sprocket, and the side of the sprocket is fixedly connected to a second sprocket. A chain is provided on the circumferential surface of the first sprocket. The first sprocket is connected to the second sprocket via the chain. The other end of the rotating rod is fixedly connected to an eccentric wheel, and the side of the eccentric wheel is fixedly connected to a vibration rod.

[0011] Furthermore, there are two brackets and eccentric wheels, which are symmetrical about each other along the vertical central axis of the vibrating rod, so that the force on both ends of the vibrating rod is balanced, and the shaking or displacement caused by the shift of the center of gravity during vibration is avoided. The circumferential surfaces of the wire roll and the storage roll are fixedly connected with partitions. Several partitions are arranged in a linear array along the circumferential surfaces of the wire roll and the storage roll, which can divide the twisted wire into multiple independent areas to prevent tangling and confusion, and ensure that the wire feeding and winding are carried out in an orderly manner.

[0012] Furthermore, spokes are provided on the sides of sprocket one and sprocket two. The number of spokes is set to several and arranged in a circumferential array on the sides of sprocket one and sprocket two. This reduces the weight of the sprockets while ensuring the structural strength and transmission stability of the sprockets, thereby reducing energy consumption and inertial load during rotation and improving transmission efficiency.

[0013] This utility model has the following beneficial effects: 1. This utility model utilizes the coordinated operation of rollers, shafts, and gears within the rolling mechanism to uniformly roll aluminum alloy strands, effectively releasing internal stress. Equal gear teeth ensure consistent rolling speed, while the spoke design reduces weight while maintaining strength. The overall structure is stably supported by vertical plates, significantly improving stress release and providing quality assurance for subsequent processing and use.

[0014] 2. This utility model utilizes the interplay of components such as the rotating rod, vibrating rod, and sprocket within the vibration mechanism. The rotating rod is driven by the power of gear one, which in turn drives the vibrating rod to generate vibration via an eccentric wheel. No additional drive source is required, saving energy. Two symmetrical supports and the eccentric wheel ensure balanced and stable vibration. The spoke design reduces the weight of the sprocket while maintaining its strength. It can be used in conjunction with a roller pressing mechanism to further release the stress in the aluminum alloy stranded wire through vibration, improving the comprehensiveness and effectiveness of stress release and enhancing the practicality of the device.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model is an aluminum alloy stranded wire stress relief device, including a body 1, a support foot pad 2 fixedly connected to the bottom of the body 1, a support plate 3 fixedly connected to the side of the body 1, a motor 4 fixedly connected to the side of the support plate 3, a wire coil 5 fixedly connected to the end of the output shaft of the motor 4, a support plate 6 fixedly connected to the side of the body 1, a motor 7 fixedly connected to the side of the support plate 6, a storage coil 8 fixedly connected to the end of the output shaft of the motor 7, and a roller pressing mechanism 9 provided inside the body 1. The roller pressing mechanism 9 includes a vertical plate 91, the bottom of which is fixedly connected to the inner side of the machine body 1. A motor 3 92 is fixedly connected to the side of the vertical plate 91. A rotating shaft 1 93 is fixedly connected to the end of the output shaft of the motor 3 92. A roller 1 94 is fixedly connected to the circumferential surface of the rotating shaft 1 93. A gear 1 95 is fixedly connected to one end of the rotating shaft 1 93. A rotating shaft 2 96 is rotatably connected to the side of the vertical plate 91. A roller 2 97 is fixedly connected to the circumferential surface of the rotating shaft 2 96. A gear 2 98 is fixedly connected to one end of the rotating shaft 2 96. Gear 1 95 and gear 2 98 mesh with each other.

[0021] As shown in the figure, there are several support feet 2 arranged in a linear array at the bottom of the body 1, which increases the force-bearing area between the body 1 and the contact surface, making the overall force of the device more uniform, effectively enhancing the placement stability, and preventing displacement or shaking caused by vibration during operation. There are two support plates 3 and 6, which are symmetrical to each other along the vertical central axis of the coil 5, which can balance the weight of the load-bearing components, ensure their coaxiality and stability during operation, and improve the reliability and service life of the device.

[0022] As shown in the figure, spokes are provided on the sides of gear 1 95 and gear 2 98. The number of spokes is set to a certain number and is arranged in a circumferential array on the sides of gear 1 95 and gear 2 98. While ensuring the structural strength of the gears, the weight of the gears is reduced, and the energy consumption and inertia during rotation are reduced. The number of teeth of gear 1 95 is equal to the number of teeth of gear 2 98, which can ensure that the rotation speed is the same and the direction of rotation is opposite during meshing transmission.

[0023] As shown in the figure, there are several rollers 94 arranged in a linear array on the circumference of the rotating shaft 93, and several rollers 97 arranged in a linear array on the circumference of the rotating shaft 96. This can form multiple sets of rolling pressure on the aluminum alloy stranded wire, improve the overall stress release efficiency, and ensure the stability of the stranded wire performance.

[0024] As shown in the figure, a vibration mechanism 10 is provided inside the body 1. The vibration mechanism 10 includes a bracket 101. The bottom of the bracket 101 is fixedly connected to the inner side of the body 1. A rotating rod 102 is rotatably connected to the inner side of the bracket 101. A sprocket 103 is fixedly connected to one end of the rotating rod 102. A sprocket 104 is fixedly connected to the side of the gear 95. A chain 105 is provided on the circumferential surface of the sprocket 103. The sprocket 103 is connected to the sprocket 104 through the chain 105. An eccentric wheel 106 is fixedly connected to the other end of the rotating rod 102. A vibration rod 107 is fixedly connected to the side of the eccentric wheel 106.

[0025] As shown in the figure, there are two brackets 101 and two eccentric wheels 106, which are symmetrical to each other along the vertical central axis of the vibrating rod 107, so that the two ends of the vibrating rod 107 are evenly stressed and avoid shaking or shifting due to the shift of the center of gravity during vibration. The circumferential surfaces of the wire roll 5 and the storage roll 8 are fixedly connected with partitions 108. There are several partitions 108, which are arranged in a linear array along the circumferential surfaces of the wire roll 5 and the storage roll 8. They can divide the twisted wire into multiple independent areas to prevent tangling and confusion, and ensure that the wire feeding and winding are carried out in an orderly manner.

[0026] As shown in the figure, sprocket 103 and sprocket 204 have spokes on their sides. The number of spokes is set to several, which are arranged in a circumferential array on the sides of sprocket 103 and sprocket 204. This reduces their weight, lowers energy consumption and inertial load during rotation, and improves transmission efficiency while ensuring the structural strength and transmission stability of the sprockets.

[0027] A specific application of this embodiment is as follows: A worker places the stress-relieving stranded wire onto the coil 5, starts motor 4, whose output shaft drives the coil 5 to rotate, and starts motor 3 92, whose output shaft drives shaft 93 to rotate. Roller 94 on shaft 93 rotates synchronously with shaft 93. Simultaneously, gear 95 at the end of shaft 93 meshes with gear 98 at the end of shaft 96. Since they have the same number of teeth, gear 98 drives shaft 96 to rotate in the opposite direction at the same speed, causing roller 97 on shaft 96 to rotate synchronously in the opposite direction to roller 94. The aluminum alloy stranded wire passes between the two sets of rollers. Under the continuous rolling action of roller 94 and roller 97, the internal stress is gradually released. The multiple sets of rollers arranged in a linear array achieve multiple rolling operations, improving rolling efficiency and ensuring uniform stress distribution across the stranded wire, thus achieving efficient and stable stress relief.

[0028] The second motor 7 is started, and its output shaft drives the winding coil 8 to rotate, thus storing the aluminum alloy stranded wire. The first gear 95 rotates, driving the second sprocket 104 on the side to rotate synchronously. The second sprocket 104 drives the first sprocket 103 to rotate through the chain 105, which in turn causes the rotating rod 102 to rotate. The eccentric wheel 106 at the other end of the rotating rod 102 rotates with it. Due to the shift in the center of gravity of the eccentric wheel 106, the vibrating rod 107 is driven to vibrate. The two symmetrical supports 101 and the eccentric wheel 106 ensure the stability of the vibration, so that the vibration is applied evenly to the aluminum alloy stranded wire. This, combined with the rolling mechanism 9, enhances the stress release effect.
