Description

Technical Field

[0001] The present application relates to the technical field of graphite wire production, and in particular to a graphite wire preparation device and method for grounding of power engineering. Background Art

[0002] Proper grounding of transmission line towers is crucial for reducing lightning tripping. Tower grounding grids are essential for protecting transmission lines from lightning strikes. Practical operational experience demonstrates that reducing grounding resistance is an effective measure for improving line lightning resistance and reducing lightning tripping rates. To effectively improve the grounding characteristics of tower grounding grids within limited construction areas, power supply companies are using flexible graphite composite grounding materials for the design and construction of transmission line tower grounding. Compared to traditional metal grounding materials such as galvanized steel and mild steel, flexible graphite composite grounding materials, primarily based on highly conductive flake graphite, allow for flexible grounding design and construction tailored to the specific terrain, resolving the inherent rigidity of metal grounding materials, which cannot be bent or flexed. Furthermore, conventional steel grounding systems can corrode and fracture over extended periods of operation, failing to guarantee the long-term effectiveness of tower grounding performance. To address the corrosion issues associated with metal tower grounding systems, graphite grounding materials have been widely used in transmission tower grounding systems in recent years. Flexible graphite grounding material is a widely used graphite grounding product. Due to its excellent conductivity, strong plasticity and wide range of applications, it is also widely used in grounding bodies.

[0003] The preparation of flexible graphite grounding materials requires the production of graphite wire, which is then cut using a cutting device. Traditional cutting devices typically use a single saw blade. If a blade becomes damaged during the cutting process, the entire production line must be stopped to replace it, impacting overall production efficiency. Therefore, the present invention provides a device and method for preparing graphite wire for power engineering grounding. Summary of the Invention

[0057] Specifically, the mounting base 1 is fixedly connected to the frame through a connecting bracket; a center hole 11 is provided at the center position of the reversing base 2, and the reversing base 2 is fixedly mounted on the output shaft of the first drive motor 8 through the center hole 11; an upper rotating hole 12 and a lower rotating hole 13 are provided at the upper and lower ends of the reversing base 2, respectively, and the upper cutting assembly 3 and the lower cutting assembly 4 are rotatably connected to the reversing base 2 through the upper rotating hole 12 and the lower rotating hole 13, respectively, for realizing the pressing and lifting actions; the first drive motor 8 and the second drive motor 9 can both be servo motors.

[0058] The upper cutting assembly 3 and the lower cutting assembly 4 both include a rotating seat 16 and a cutting saw blade 17. One end of the rotating seat 16 is fixedly connected to a first rotating rod 18, and the rotating seat 16 is rotatably connected to the reversing seat 2 through the first rotating rod 18. Specifically, the rotating seat 16 is rotatably mounted in the rotating hole through the first rotating rod 18; the end of the first rotating rod 18 away from the rotating seat 16 passes through the reversing seat 2 and is rotatably connected to a first driven gear 19. The cutting saw blade 17 is rotatably mounted on the other end of the rotating seat 16 through a second rotating rod 20. A second driven gear 21 is fixedly mounted on the second rotating rod 20; the first driven gear 19 is meshed and connected with the second driven gear 21; a transmission gear 10 is fixedly mounted on the output shaft of the second drive motor 9, and when the upper cutting component 3 rotates to the top with the reversing seat 2, the transmission gear 10 is meshed and connected with the first driven gear 19 on the upper cutting component 3; when the lower cutting component 4 rotates to the top with the reversing seat 2, the transmission gear 10 is meshed and connected with the first driven gear 19 on the lower cutting component 4.

[0059] Both the upper reset assembly 5 and the lower reset assembly 6 include a base 22, a guide rod 23, a top seat 24, and a reset spring 25. The base 22 is fixed to the reversing seat 2, the guide rod 23 is movably mounted in a guide hole on the base 22, the top seat 24 is fixed to the top of the guide rod 23, and the reset spring 25 is sleeved on the guide rod 23. One end of the reset spring 25 is connected to the lower surface of the top seat 24, and the other end is connected to the upper surface of the base 22. Specifically, the top seat 24 is provided with a first roller for abutting against the rotating seat 16, which can reduce friction and improve the flexibility of relative movement between the structures.

[0060] An upper limit block 14 and a lower limit block 15 for respectively limiting the rotation of the upper cutting assembly 3 and the lower cutting assembly 4 are fixed on the reversing seat 2 . The upper limit block 14 and the lower limit block 15 are symmetrically arranged on the upper and lower sides of the reversing seat 2 .

[0061] It is understood that the rotating seat 16 on the upper cutting assembly 3 is limited by the upper stop block 14 and the upper reset assembly 5; the rotating seat 16 on the lower cutting assembly 4 is limited by the lower stop block 15 and the lower reset assembly 6.

[0062] The holding assembly 7 includes a holding cylinder 26 and a holding base 27. The holding base 27 is fixed to the telescopic rod of the holding cylinder 26.

This effectively improves the positioning stability of the reversing base 2. When the positioning cylinder 28 is in the advance state, the telescopic rods are inserted into the corresponding positioning slots 29.

In this embodiment, the positioning cylinder 28 is located directly below the first drive motor 8, and the second drive motor 9 is located directly above the first drive motor 8.

[0064] It should be noted that when the upper cutting assembly 3 or the lower cutting assembly 4 rotates to the top and is connected to the second drive motor 9 , the positioning electric cylinder 28 cooperates with the corresponding positioning groove 29 to achieve positioning of the reversing seat 2.

[0065] Specifically, the edge line of the telescopic rod end surface of the positioning electric cylinder 28 is chamfered to facilitate alignment and insertion into the positioning groove 29 .

[0066] The present application also provides a method for preparing a graphite wire for grounding in a power engineering project. The method is implemented by the above-mentioned graphite wire preparation device for grounding in a power engineering project, and comprises the following steps:

[0067] Place the graphite wire to be cut in the cutting area, start the first drive motor 8, and control the reversing seat 2 to rotate through the first drive motor 8, so that the upper cutting assembly 3 rotates to the top and is connected to the second drive motor 9;

[0068] The second drive motor 9 is started to drive the upper cutting assembly 3 via the second drive motor 9, so that the cutting saw blade 17 on the upper cutting assembly 3 rotates;

[0069] Start the top holding assembly 7, and drive the upper cutting assembly 3 to rotate downward through the top holding assembly 7, so that the cutting saw blade 17 on the upper cutting assembly 3 is close to the graphite wire to be cut, thereby achieving cutting of the graphite wire;

[0070] When it is necessary to replace the lower cutting component 4 for cutting, the cutting saw blade 17 of the upper cutting component 3 is separated from the graphite wire by resetting the top holding component 7, and then the first drive motor 8 is used to control the reversing seat 2 to rotate, and the lower cutting component 4 is rotated to the top, and is connected to the second drive motor 9. Then the second drive motor 9 is restarted, and the second drive motor 9 drives the cutting saw blade 17 on the lower cutting component 4 to rotate. At the same time, the top holding component 7 is started again, so that the cutting saw blade 17 on the lower cutting component 4 is aligned with the graphite wire to be cut, so that the lower cutting component 4 can cut the graphite wire.

[0071] When the upper cutting assembly 3 or the lower cutting assembly 4 rotates to the top and is connected to the second drive motor 9, the positioning electric cylinder 28 can be started. At this time, the telescopic rod of the positioning cylinder extends into the corresponding positioning groove 29, which can realize the positioning of the reversing seat 2.

[0072] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
