Description

Technical Field

[0001] This utility model relates to the field of new materials or new energy technology, and in particular to a clamping device, a power transmission vehicle and a graphitization furnace. Background Technology

[0002] A graphitization furnace is a device for processing carbon materials into artificial graphite. It has a rectangular furnace body with conductive electrodes at the head and / or tail. The power supply device supplies power by connecting the electrodes and aluminum bars.

[0003] Currently, most graphitization furnaces are fixed structures. The power supply method for fixed graphitization furnaces requires each furnace to be equipped with a power supply device, and the corresponding power supply aluminum busbar also needs to be installed next to each fixed graphitization furnace. This method results in high construction costs for the aluminum busbar and high circuit losses.

[0004] To address the aforementioned issues, a mobile power transmission vehicle is used for the power supply equipment. Aluminum bars are installed beside multiple furnace bodies, and the power transmission vehicle is equipped with clamps that hold the aluminum bars and conductive electrodes, thereby ensuring circuit continuity. This method simplifies the construction cost of the aluminum bars.

[0005] Existing electrode clamps on power transmission vehicles, such as the power transmission vehicle equipment and system disclosed in patent publication number CN118149599A, use a lever-structured clamping arm to install the clamping plate. The clamping arm is driven by a hydraulic rod to rotate, thereby opening and closing the clamping plate. The clamping plate needs to be hinged to the clamping arm and also requires the addition of a spring to ensure that the clamping plate overcomes the rotation of the clamping arm and fits against the aluminum busbar or electrode surface, resulting in an overly complex clamping plate installation structure.

[0006] The purpose of this utility model is to provide a clamping device, a power supply vehicle, and a graphitization furnace, which simplifies the installation of the clamping plate.

[0008] In the above solution, the clamping arm of the existing lever structure is optimized into a scissor-type telescopic frame, so that the two clamping plates open and close in a parallel manner. The movement trajectory of the clamping plates and the ends of the scissor-type telescopic frame is the same, so that the clamping plates do not need to be hinged or have springs or other components, which greatly simplifies the installation structure of the clamping plates.

[0012] Preferably, two first conductive aluminum plates are provided on the upper and lower surfaces of the second frame, and two second conductive aluminum plates are provided on the upper and lower surfaces of the first frame. The second groove is provided on one side of the two second conductive aluminum plates facing each other.

[0013] This utility model also provides a power transmission vehicle, including a vehicle body, a busbar aluminum frame and a plurality of the above-mentioned clamping devices. The busbar aluminum frame is vertically arranged on the vehicle body, and the clamping devices are provided on one side and the top of the busbar aluminum frame. The clamping plates on the clamping devices are arranged away from the busbar aluminum frame.

[0014] Preferably, the vehicle body is provided with guide wheels at the ends and with traveling wheels at the bottom.

[0015] Preferably, the top of the busbar aluminum frame is provided with a first camera for detecting the movement position of the power transmission vehicle, and the vehicle body is provided with a second camera for detecting the movement state of the clamping plate.

[0016] This utility model also provides a graphitization furnace, including multiple furnace bodies arranged in the X direction, multiple second tracks extending in the Y direction, a first track extending in the X direction, and the aforementioned power supply vehicle running on the first track. The furnace bodies run on the second tracks, and multiple electrodes are provided on at least one side surface of each furnace body. Aluminum bars are provided on the sides of the multiple furnace bodies, and clamps at corresponding positions on the power supply vehicle clamp the aluminum bars and electrodes respectively to conduct the aluminum bars, current channels, and electrodes.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0038] like Figure 1 , Figure 2 As shown, the clamping device 33 provided in this embodiment includes a clamping plate 19, a hydraulic rod 20, a second frame 21, a first conductive aluminum plate 22, a second conductive aluminum plate 23, a first frame 29, and a scissor-type telescopic frame 31.

[0039] Both the first frame 29 and the second frame 21 are rectangular frames, and each has a first groove 32 on its inner surface along its length. The scissor-type telescopic frame 31 has end A and end B on one side, and end C and end D on the other side. End B is hinged to the first frame 29 via a pivot, and end B is a rotating, non-moving end. End A slides in the first groove 32 on the first frame 29 via a pivot. Ends C and D slide in the first groove 32 on the second frame 21 via pivots. Ends C and D are respectively connected to clamping plates 19. A hydraulic rod 20 connects to ends A and B. By extending and retracting the hydraulic rod 20, end A is driven to move closer to or open towards end B, thereby opening and closing the two clamping plates 19 on ends C and D to clamp or release the load.

[0040] The first frame 29 has a second conductive aluminum plate 23 on both its upper and lower surfaces. One end of the second conductive aluminum plate 23 is connected to the first frame 29, and the other end extends toward the second frame 21. A second groove 231 is provided on one side of the two second conductive aluminum plates 23 facing each other. The second groove 231 runs through the line connecting the first frame 29 and the second frame 21.

[0041] The upper and lower surfaces of the second frame 21 are provided with first conductive aluminum plates 22. One end of the first conductive aluminum plate 22 is connected to the second frame 21, and the other end extends into the second sliding groove 231. As the scissor-type telescopic frame 31 moves, the first conductive aluminum plate 22 slides in the second sliding groove 231 of the second conductive aluminum plate 23.

[0042] like Figure 3 As shown, this utility model also provides a power transmission vehicle 2, which includes a vehicle body 30, a first camera 15, a busbar aluminum frame 16, a second camera 18 and a plurality of the above-mentioned clamping devices 33.

[0043] The vehicle body 30 has a first guide wheel 12 at one end and a second guide wheel 17 at the other end. The bottom of the vehicle body 30 has adjacent first driving wheel 11 and first driven wheel 10, as well as adjacent second driving wheel 8 and second driven wheel 9. The first driving wheel 11 is positioned close to the first guide wheel 12. The second driving wheel 8 is positioned close to the second guide wheel 17. The vehicle body 30 contains motors (unlabeled) for driving the first driving wheel 11 and the second driving wheel 8 respectively. The driving and driven wheels cooperate to enable the trolley to cross the second track 4.

[0044] The busbar aluminum frame 16 is vertically mounted on the vehicle body 30. A clamping device 33 is defined as an electrode clamp 13 on one side of the busbar aluminum frame 16, and a clamping device 33 is defined as an aluminum bar clamp 14 on the top of the busbar aluminum frame 16. The electrode clamps 13 are arranged in a rectangular array on the side of the busbar aluminum frame 16, corresponding one-to-one with the electrodes 7 on the furnace body 1 (e.g., ...). Figure 5 (As shown). The clamping plates 19 on the clamping device 33 are all positioned away from the busbar aluminum frame 16.

[0045] The top of the busbar aluminum frame 16 is equipped with a first camera 15 for detecting the movement position of the trolley 2, and the body 30 is equipped with a second camera 18 for detecting the movement state of the clamping plate 19. Three second cameras 18 are installed on the body 30, mounted on the side away from the electrode clamp 13. The first camera 15 and the second camera 18 are electrically connected to the control center of the graphitization furnace to send signals to the control center, which then issues corresponding commands to the trolley 2 or the clamping device 33 to perform corresponding actions.

[0046] like Figure 3 , Figure 4 As shown, this utility model also provides a graphitization furnace, which includes multiple furnace bodies 1 arranged in the X direction, multiple second tracks 4 extending in the Y direction, a first track 3 extending in the X direction, and the aforementioned power supply vehicle 2 running on the first track 3. Two sets of the first track 3 are spaced apart in the Y direction, and two sets of corresponding wheels (first driving wheel 11, first driven wheel 10, second driven wheel 9, and second driving wheel 8) are also provided on the power supply vehicle 2. A guide groove 6 is provided between the two sets of first tracks 3, and the first guide wheel 12 and the second guide wheel 17 are adapted to the guide groove 6. The number of second tracks 4 corresponds to the number of furnace bodies 1, allowing the furnace bodies 1 to run on the second tracks 4. The X and Y directions are perpendicular to each other on the same top-view projection plane. An aluminum bar 5 is provided above one side of each of the multiple furnace bodies 1. The side of the furnace body 1 closest to the aluminum bar 5 is a power supply station, and the power supply vehicle 2 runs on the first track 3 between each power supply station. Positive and negative aluminum bars are respectively set at both ends of the X-direction of multiple furnace bodies 1. The furnace body 1 runs on the second track 4 to be able to enter or exit the power supply station for power supply. The number of power supply vehicles 2 is reasonably set according to actual needs. For example, if there is one vehicle, it can be a positive and a negative power supply vehicle. If there are two vehicles, one can be a positive vehicle and the other a negative vehicle, etc.

[0047] like Figure 5 As shown, the furnace body 1 has multiple electrodes 7 on at least one side surface. In use, the power supply trolley 2 runs along the first track 3. When the first camera 15 detects the camera detection point 28 on the furnace body 1, it sends a signal to the control center to stop the power supply trolley 2. Then, it sends a command to drive the clamping plate 19 at the upper end of the power supply trolley 2 to clamp the aluminum busbar 5 located above one side of the furnace body 1. The clamping plate 19 on the side of the power supply trolley 2 clamps the electrodes 7, connecting the aluminum busbar 5, the current channel (first frame 29, second frame 21, and clamping plate 19), and the electrodes 7. Current flows from the aluminum busbar 5 through the aluminum busbar clamp 14 into the busbar frame 16, and then from the busbar frame 16 through the electrode clamp 13 into the electrodes 7, thereby realizing the power supply operation of the graphitization furnace (e.g., Figure 10 , Figure 11 (As shown).

[0048] like Figure 6 As shown, the second track 4 divides the first track 3 and the guide groove 6 into multiple sections. Each section of the first track 3 has a bevel (such as a first bevel 25 and a second bevel 24) near the end of the second track 4, and the bevel is located on the upper surface of the first track 3. The height of the second track 4 is lower than the height of the first track 3 and the guide groove 6. The guide groove 6 has a flared end (a first flared end 26 and a second flared end 27) above the end of the second track 4.

[0049] like Figure 6 , Figure 7 , Figure 8 As shown, driven by the first driving wheel 11 and the second driving wheel 8, the first guide wheel 12 on the trolley 2 leaves the first horn opening 26 and then enters the second horn opening 27, ensuring that the trolley 2 does not deviate when crossing the track. Because the second track 4 is lower than the first track 3, the first driving wheel 11 on the trolley 2 will enter a suspended state and lose power when it travels from the first ramp 25 to above the second track 4. At this time, the trolley 2 is driven by the second driving wheel 8. This causes the suspended first driving wheel 11 to enter the first track 3 and make contact with it via the second ramp 24. Figure 9 As shown, when the second drive wheel 8 travels above the second track 4, it will enter a suspended state and lose power. At this time, the first drive wheel 11 will continue to drive the trolley 2 forward. Subsequently, the second guide wheel 17 leaves the first flared opening 26 of the upper guide groove 6 and enters the next guide groove 6 through the second flared opening 27. The two guide wheels maintain the relative position of the trolley 2 and the first track 3.

[0050] When the power transmission vehicle 2 is running on the first track 3, such as Figure 10 As shown, clamping plate 19 and scissor-type telescopic frame 31 are in their initial retracted state to prevent interference with other equipment. When the first camera 15 identifies the position, the hydraulic rod 20 retracts, causing the scissor-type telescopic frame 31 to extend, driving clamping plate 19 to perform a clamping action. The second camera 18 identifies the clamping state of clamping plate 19 until the clamping of electrode 7 and aluminum busbar 5 is complete.

[0051] This utility model provides a graphitization furnace with a power supply system, which simplifies plant layout, reduces investment costs, allows for flexible power supply processes, and improves equipment stability. The graphitization furnace transport vehicle track (second track 4) and the power supply vehicle track (first track 3) are designed to cross over each other, allowing the power supply vehicle to traverse between multiple furnace bodies 1 and reach any power supply station beside any furnace body 1. Power supply is independent of furnace operation and does not interfere with each other. The power supply vehicle is equipped with a busbar aluminum frame for direct power transmission, simplifying equipment structure and reducing energy consumption. Flexible power supply can be implemented according to different processes, thereby increasing production capacity and saving costs.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
