Description

Technical Field

[0001] This utility model relates to the field of cable stranding technology, and in particular to a cable stranding assist device. Background Technology

[0002] Currently, when twisting long high-voltage three-phase cables, operators generally need to use their wrists and waist to swing the main cable, which can easily lead to waist and wrist injuries. Another person is responsible for assisting at the other end to prevent the cable from being twisted incorrectly, requiring them to squat throughout the process. Alternatively, more operators are needed to twist the three cables one by one in sequence while squatting throughout the process. Because manual labor requires a lot of strength, the twisting density is inconsistent and cannot meet the set requirements.

[0003] The high-voltage three-phase cable stranding method in related technologies has problems such as being time-consuming and labor-intensive, being prone to twisting the cable incorrectly, and potentially injuring operators. It also requires a large number of operators, has low stranding efficiency, and poor production quality.

[0004] Therefore, how to improve the efficiency of cable stranding and reduce the labor intensity of operators is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0029] The core of this invention is to provide a cable stranding assist device, which can significantly reduce the difficulty of cable stranding and improve the quality of stranding.

[0030] 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.

[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to Figures 1 to 6 , Figure 1 A schematic diagram of a specific embodiment of the cable stranding assist device provided by this utility model; Figure 2 for Figure 1 Top view of the cable stranding assist device shown; Figure 3 for Figure 1 Side view of the cable stranding assist device shown; Figure 4 for Figure 1 The front view of the cable stranding assist device shown; Figure 5 for Figure 4 A cross-sectional view of the cable stranding assist device shown in Figure AA; Figure 6 This is a schematic diagram of the guide limiting groove, bottom cover, and bottom cover power component in the cable stranding assist device provided by this utility model.

[0033] In this embodiment, the cable 100 stranding assist device includes a support body 1, a plurality of rolling auxiliary parts 2 and a driving part. The support body 1 has a cylindrical stranding cavity 11 for inserting the cable 100 inside, and the stranding cavity 11 extends from one end of the support body 1 to the other end. The extension direction of the support body 1 is parallel to the extension direction of the cable 100.

[0034] The rolling auxiliary component 2 is disposed on the support body 1, and at least a portion of the circumferential surface of the rolling auxiliary component 2 protrudes from the inner wall of the support body 1. Each rolling auxiliary component 2 is arranged at least circumferentially along the inner wall of the support body 1 so that the cable 100 can contact and connect with the rolling auxiliary component 2 during the swinging process.

[0035] The driving component is disposed on the support body 1. The driving component is used to drive the rolling auxiliary component 2 to rotate, and the rotation direction of the rolling auxiliary component 2 is perpendicular to the extension direction of the support body 1.

[0036] Specifically, the cable 100 can be a three-phase power cable 100, especially a high-voltage three-phase cable for high-speed trains or a three-phase motor cable 100; by twisting multiple cables 100 into a whole according to specific rules, generally by manually swinging a single cable 100 in sequence, so that multiple cables 100 are intertwined, and a twister is used to twist each cable 100; the twisting cavity 11 can be cylindrical, and the cylindrical structure is more suitable for the cable 100 to move around in the twisting cavity 11.

[0037] Furthermore, the rotation direction of the rolling auxiliary component 2 should be opposite to the swing direction of the cable 100. That is, when the cable 100 swings clockwise, the rolling auxiliary component 2 should rotate counterclockwise. The rolling auxiliary component 2 should be able to provide upward assistance to the cable 100. The driving component can be a motor or other components, and the start, stop or speed of the driving component can be controlled by a controller. Specifically, the number of driving components can be multiple, corresponding one-to-one with the rolling auxiliary component 2, to achieve single driving, or a single driving component can drive several rolling auxiliary components 2, as long as it is convenient to control.

[0038] Furthermore, several rolling auxiliary components 2 are arranged on the inner wall of the support body 1 in both the circumferential and extension directions. In order to ensure uniform force distribution, the rolling auxiliary components 2 can be evenly distributed on the inner wall of the support body 1.

[0039] The cable 100 twisting assist device provided by this utility model, through the setting of a support body 1, and the setting of a twisting cavity 11 inside the support body 1, allows the cables 100 to be swung one by one in the twisting cavity 11, thereby twisting multiple cables 100 together. During the swinging of the cables 100, a squeezing force is generated between the cables 100 and the inner wall of the support body 1. This application utilizes the force between the cables 100 and the inner wall of the support body 1, by adding a rolling auxiliary component 2 and a driving component. Under the action of the driving component, the rolling auxiliary component 2 provides assistance for the swinging of the cables 100 through its own rotation, thereby effectively reducing the labor intensity of the operator. At the same time, due to the setting of the support body 1, the height of the cables 100 is increased, and the operator can complete the twisting operation while standing, making the operation convenient.

[0040] In some embodiments, a guide limiting groove 12 is also provided on the inner wall of the support body 1. The guide limiting groove 12 is connected to the stranded cable cavity 11. The extension direction of the guide limiting groove 12 is parallel to the extension direction of the support body 1, and the two ends of the guide limiting groove 12 respectively penetrate the two end faces of the support body 1, so that the cable 100 can be inserted from one end of the support body 1 and exit from the other end. That is to say, the guide limiting groove 12 extends from one end of the support body 1 to the other end, and the guide limiting groove 12 is a through groove, so that the cable 100 can be inserted into the guide limiting groove 12 from one end of the support body 1, which facilitates the installation of the cable 100. The setting of the guide limiting groove 12 can ensure that the cable 100 can pass smoothly through the support body 1, and can also play a certain role in constraining and straightening the cable 100. Furthermore, to facilitate the installation of cable 100, a sliding block can be installed within the guide limiting groove 12. A lead wire can be installed on the sliding block, and one end of cable 100 can be connected to the sliding block. After connection, by pulling the lead wire, cable 100 can pass through to form the support body 1, facilitating operation. A slide rail can also be installed within the guide limiting groove 12. Under the precise guidance of the slide rail, the sliding block smoothly and continuously pushes one end of cable 100 towards the other end of the support body 1 until the entire cable 100 is smoothly introduced into the support body 1, achieving automated cable entry. Alternatively, cable 100 can be pushed from one end of the support body 1, moved to the other end, and then pulled out, offering convenient operation.

[0041] In some embodiments, the guide limiting groove 12 is disposed on the inner bottom of the support body 1, and there are multiple guide limiting grooves 12. Each guide limiting groove 12 is arranged along the circumference of the support body 1. By setting multiple guide limiting grooves 12, multiple cables 100 can be passed through at the same time, thereby improving efficiency. The guide limiting grooves 12 can be set at intervals to facilitate pushing or pulling the cables 100 with the help of tools.

[0042] In some embodiments, a bottom cover 13 is also included. The bottom cover 13 is adjustablely disposed at the bottom of the guide limiting groove 12. The bottom cover 13 can move to the surface of the guide limiting groove 12 and be flush with the inner wall of the support body 1. Specifically, the bottom cover 13 is disposed at the bottom of the guide limiting groove 12 and forms the bottom surface of the guide limiting groove 12. The bottom cover 13 can be an automatically lifting bottom cover 13, controlled by a controller. When the cable 100 passes through the support body 1 and is taken out from the guide limiting groove 12, the cable 100 can be pushed out by moving the bottom cover 13. Alternatively, the cable 100 can be manually taken out from the guide limiting groove 12, and then the bottom cover 13 can be moved to be flush with the inner wall of the support body 1. This reduces the chance that the cable 100 will re-enter the guide limiting groove 12 during the twisting process, thus affecting the twisting process.

[0043] In some embodiments, a bottom cover power component 14 is also included. The bottom cover power component 14 is disposed on the support body 1 and is used to push the bottom cover 13 from the bottom of the guide limiting groove 12 to be flush with the inner wall of the support body 1. The bottom cover power component 14 can be a cylinder, and the movement of the bottom cover 13 is realized by the extension and retraction of the bottom cover power component 14. Of course, the bottom cover 13 can also be omitted, and the cable 100 will cross the guide limiting groove 12 under the action of inertia during the swinging process. The bottom cover 13 and the bottom cover power component 14 can completely prevent the cable 100 from entering the guide limiting groove 12 during the twisting process, and can also push the cable 100 in the guide limiting groove 12 into the twisting cavity 11 after the cable 100 passes through the support body 1.

[0044] In some embodiments, there are multiple guide limiting grooves 12, and the width of each guide limiting groove 12 is different. A guide limiting groove 12 of appropriate size can be selected according to the size of the cable 100 to improve the adaptability. Furthermore, the guide limiting groove 12 is clearance-fitted with the cable 100 to straighten the cable 100.

[0045] In some embodiments, the rolling auxiliary component 2 is a rolling auxiliary wheel. The rolling auxiliary wheel can effectively reduce the output force of the operator's wrist or waist, reduce the difficulty of the stranding operation, and significantly reduce the difficulty of operation and improve the stranding quality with the help of the drive component. Furthermore, the surface of the rolling auxiliary wheel is provided with a number of protrusions 21. By setting the protrusions 21, the protrusions 21 can increase the friction between the rolling auxiliary wheel and the cable 100, and provide greater assistance to the cable 100 during the swinging process.

[0046] In some embodiments, the support body 1 is further provided with an opening 15, which is connected to the stranded cavity 11 and extends in a direction parallel to the extension direction of the stranded cavity 11; the opening 15 allows the cable 100 after stranding to be taken out from the stranded cavity 11.

[0047] In some embodiments, the cross-section of the stranded cavity 11 is circular, that is, the stranded cavity 11 is a cylindrical structure, and the opening 15 is located on the top side of the stranded cavity 11 to prevent the cable 100 from coming out of the opening 15. The swing direction of the cable 100 should be from the bottom of the stranded cavity 11 of the support body 1 toward the side of the support body 1 where the opening 15 is not provided. Then, after the cable 100 passes the highest point of the stranded cavity 11 of the support body 1, it returns to the bottom of the stranded cavity 11 under the action of inertia. The opening 15 will not affect the stranding operation of the cable 100, and it can facilitate the removal of the cable 100 from the stranded cavity 11 after the stranding is completed.

[0048] In some embodiments, the central angle of the opening 15 relative to the axis of the stranded cavity 11 is 85-95°, and can be 90°; that is, the opening 15 avoids about one-quarter of the space of the stranded cavity 11, so that the inner wall of the support body 1 forms a three-quarters arc design, so that when the cable 100 moves in the upper part of the stranded cavity 11, it can make full use of the principle of inertia to achieve a smooth switching of the position of the cable 100; this switching process will be repeated continuously until multiple cables 100 are twisted together.

[0049] In some embodiments, a support wheel 3 is also included, which is disposed at the bottom of the support body 1. The wheel is a swivel wheel, which facilitates the movement of the support body 1 in any direction.

[0050] Specifically, in one embodiment, the cable 100 stranding assist device includes a support body 1, several rolling auxiliary parts 2, a drive component, and support wheels 3. The support body 1 is placed on the ground. Inside the support body 1, there is a guide limiting groove 12. Rolling auxiliary wheels with stable rotation speed are arranged at equal intervals and in rows around the inner perimeter of the support body 1 to provide assistance for the stranding process. Three guide limiting grooves 12 are arranged at the bottom of the support body 1 for positioning and guiding the high-voltage power cable 100. The operator places one end of the cable 100 into these guide limiting grooves 12 to ensure that each cable 100 can accurately fit into the groove of the guide limiting groove 12 and be above the guide limiting groove 12. After the three cables 100 are placed in sequence, the bottom cover 13 inside the guide limiting groove 12 will rise precisely into place, seamlessly filling the plane of the guide limiting groove 12, ensuring that the working surface of the entire support body 1 is flat and smooth. Subsequently, the drive components of the rolling auxiliary wheels configured inside the support body 1 start synchronously. Each rolling auxiliary wheel is equipped with a drive component for easy replacement. The stable rotation speed of the rolling auxiliary wheels provides continuous power support for the stranding process. Two operators will be located at both ends of the support body 1 respectively, applying appropriate force to the cable 100. With the help of the rolling auxiliary wheels, the stranding process is ensured to proceed smoothly.
