[0002] The Atchison graphitization furnace is a device used to convert carbon materials into artificial graphite. Its furnace body is rectangular in shape and has conductive electrodes at both the furnace head and tail. An energizer trolley supplies power to the graphitization furnace to complete the graphitization process. During power supply, the energizer trolley clamps the power supply busbar through a busbar clamping mechanism, while the electrode clamping mechanism clamps the conductive electrodes, thereby achieving electrical connection between the busbar clamping mechanism and the electrode clamping mechanism, and completing the power supply.

[0003] In existing technology, the busbar clamping mechanism and the electrode clamping mechanism are fixedly connected by a water-cooled cable. However, due to the frequent switching between the working and releasing states of the trolley, the water-cooled cable needs to move along with the electrode clamping mechanism, resulting in the water-cooled cable being subjected to large mechanical stress. After long-term use, it is prone to fatigue fracture, affecting the reliability and service life of the equipment. Utility Model Content

Detailed Implementation

[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0039] A power transmission car is a mobile device that supplies electricity to a graphitization furnace. The power transmission car is equipped with an electrode clamping mechanism and a busbar clamping mechanism that are electrically connected to each other.

[0040] The energizing car has an operating state and a released state, and can switch between the two states. When in the operating state, the electrode clamping mechanism moves forward to clamp the conductive electrode, while the busbar clamping mechanism clamps the power supply busbar to transfer current from the power supply busbar to the conductive electrode, thereby meeting the requirements of the power supply and heating process of the graphitization furnace. When in the released state, the electrode clamping mechanism releases the conductive electrode, the busbar clamping mechanism releases the power supply busbar, the electrode clamping mechanism returns to its original position, and the energizing car moves towards the next section of the graphitization furnace.

[0041] In the prior art, the busbar clamping mechanism and the electrode clamping mechanism are connected by a water-cooled cable. Because the water-cooled cable needs to move with the electrode clamping mechanism for a long time, the mechanical wear and tear is high, and it is prone to breakage. This results in an unstable connection between the electrode clamping mechanism and the busbar clamping mechanism, and poor power transmission stability of the power transmission vehicle.

[0042] To address the aforementioned defects in water-cooled cables, please refer to [link / reference]. Figure 1 and Figure 2 One specific embodiment of this application provides a power transmission vehicle. A graphitization furnace is arranged on one side of the power transmission vehicle, and a power transmission busbar is arranged directly below the power transmission vehicle.

[0043] The power transmission vehicle includes: a car body 1, an electrode clamping mechanism 2, and a busbar clamping mechanism 3. Both the electrode clamping mechanism 2 and the busbar clamping mechanism are located on the car body 1.

[0044] Specifically, the vehicle body 1 is provided with a sliding assembly 11 and a vehicle busbar 12. The vehicle busbar 12 is configured to be fixed on the sliding assembly 11 and can move synchronously under the drive of the sliding assembly 11.

[0045] The electrode clamping mechanism 2 is fixed on the sliding assembly 12 and is electrically connected to the busbar clamping mechanism 3 via the vehicle busbar 11. The busbar clamping mechanism 3 is fixedly installed on the non-moving part of the vehicle body 1.

[0046] When the power transmission vehicle is supplying power, the sliding mechanism 11 drives the electrode clamping mechanism 2 to move towards the graphitization furnace until the electrode clamping mechanism 2 clamps the conductive electrode of the graphitization furnace. The on-board busbar moves to the point where the busbar clamping mechanism can clamp the on-board busbar 11. When the power transmission vehicle stops supplying power, the sliding mechanism 11 drives the electrode clamping mechanism 2 away from the graphitization furnace until the electrode clamping mechanism 2 separates from the graphitization furnace, and the busbar clamping mechanism 3 separates from the on-board busbar 11.

[0047] The trolley of this application is equipped with an electrode clamping mechanism 2 and a busbar clamping mechanism 3, and the electrode clamping mechanism 2 and the busbar clamping mechanism 3 are electrically connected through a vehicle-mounted busbar 11. The vehicle-mounted busbars 11 are all rigid, so that the connection between the electrode clamping mechanism 2 and the busbar clamping mechanism 3 is stable and reliable.

[0048] In one specific embodiment, the busbar clamping mechanism 3 includes: a vehicle-mounted busbar clamping mechanism 31 and a main busbar clamping mechanism 32, wherein the vehicle-mounted busbar clamping mechanism 31 is connected to the main busbar clamping mechanism 32.

[0049] The busbar clamping mechanism 3 has a working state and a releasing state. When it is in the working state, the vehicle busbar clamping mechanism 31 clamps the vehicle busbar 11, and the electrode clamping mechanism 2 and the busbar clamping mechanism 3 are energized. When it is in the releasing state, the vehicle busbar clamping mechanism 31 releases the vehicle busbar 11, and the electrode clamping mechanism 2 and the busbar clamping mechanism 3 are disconnected.

[0050] The vehicle-mounted busbar clamping mechanism 31 and the vehicle-mounted busbar 11 adopt a clamping connection design, which is stable and reliable when connected, and the two can be quickly and completely separated from each other, further enhancing the ability to quickly cut off power in emergency situations, reducing safety hazards, ensuring the safety of equipment operation, extending the service life of the equipment, and improving the reliability of the system.

[0051] In this embodiment, a rigid vehicle-mounted busbar 11 is fixed to the electrode clamping mechanism 2. The vehicle-mounted busbar 11 moves along with the electrode clamping mechanism 2, and a vehicle-mounted busbar clamping mechanism 31 is provided to clamp and release the vehicle-mounted busbar 11. In other words, by replacing the water-cooled cable in the prior art with the vehicle-mounted busbar 11, the mechanical loss caused by the water-cooled cable moving with the electrode clamping mechanism 2 is eliminated, and the cost of equipment replacement is reduced.

[0052] Please see Figure 2 and Figure 3 It should be noted that the vehicle-mounted busbar 11 includes a horizontal aluminum busbar 111 and branch aluminum busbars 112. The horizontal aluminum busbar 111 is connected to at least one branch aluminum busbar 112 and is arranged perpendicular to each other. The horizontal aluminum busbar 111 is fixed on the sliding assembly 12, and the busbar clamping mechanism 3 is used to clamp the branch aluminum busbar 112.

[0053] Specifically, the vehicle-mounted busbar 11 comprises several horizontal aluminum busbars 111 and branch aluminum busbars 112 spliced ​​together, reducing the difficulty in the production and transportation process of the vehicle-mounted busbar 11.

[0054] Please see Figure 4 and Figure 5 The sliding assembly 12 includes a column 121 and a sliding seat 122. The column 121 can slide linearly back and forth on the sliding seat 122. The electrode clamping mechanism 2 is disposed on the column 121, and the vehicle busbar 11 is disposed on the side of the column 121 opposite to the electrode clamping mechanism 2.

[0055] Specifically, four uprights 121 are fixedly installed on the sliding seat 122. The bottom of the sliding seat 122 is connected to three sliding rods, so that the sliding seat 122 can move within the position set by the sliding rods. One end of the sliding rod is aligned with the direction of the conductive electrode, and the vehicle busbar 11 is fixed on the uprights 121.

[0056] For example, in the working state, the sliding component 12 is at its closest point to the conductive electrode, and the electrode clamping mechanism 2 clamps the conductive electrode at this closest point. In the released state, the sliding component 12 is at its farthest point from the conductive electrode; this prevents the electrode clamping mechanism 2 from colliding with the conductive electrode due to excessive proximity during the movement of the trolley.

[0057] Please see Figure 6 In one specific embodiment, the main busbar clamping mechanism 32 includes: two clamping arms 321, two main aluminum busbar clamps 322, and a drive cylinder 323. The drive cylinder 323 is connected to one end of each of the two clamping arms 321, and the two main aluminum busbar clamps 322 are connected to the other end of each clamping arm 321. In the working state, the drive cylinder 323 drives the clamping arms 321 to move closer to each other, so as to cause the two main aluminum busbar clamps 322 to clamp the power supply busbar together.

[0058] Please see Figure 6 and Figure 8 The busbar clamping mechanism 3 also includes a main copper plate 33, which is connected to the vehicle-mounted busbar clamping mechanism 31 and the main busbar clamping mechanism 32 respectively. The vehicle-mounted busbar clamping mechanism 31 and the main busbar clamping mechanism 32 are respectively located on both sides of the main copper plate 33.

[0059] The main copper plate 33 is shared. The vehicle busbar clamping mechanism 31 is located above the main copper plate 33, and the main busbar clamping mechanism 32 is located below the main copper plate 33. The main busbar clamping mechanism 32 and the vehicle busbar clamping mechanism 31 share the main copper plate 33, which enables the busbar clamping mechanism 3 to have good conductivity during the transmission of current.

[0060] Please see Figure 1 , Figure 6 and Figure 7 The busbar clamping mechanism 3 also includes a fixing component 34, which is rectangular in shape. Both ends of the fixing component 34 are fixed to the vehicle body 1, and the middle part of the fixing component 34 is fixed to the busbar clamping mechanism 3.

[0061] The fixing component 34 provides support for the busbar clamping mechanism 3 while insulating and isolating the busbar clamping mechanism 3 from the vehicle body 1.

[0062] Specifically, the fixing assembly 34 consists of a mounting plate 341 and an insulating plate 342. The upper and lower insulating plates 342 together clamp the middle mounting plate 341. The bottom insulating plate 342 is fixed to the busbar clamping mechanism 3. The mounting plate 341 extends outward on both sides, and mounting holes are provided in the extended parts of the mounting plate 341. Hydraulic cylinder bases 313 are arranged side by side on both sides of the upper insulating plate 342, which can fit into the mounting holes of the mounting plate 341. The fixing assembly 34, while fixing the busbar clamping mechanism 3 to the vehicle body 1, prevents current from flowing into the vehicle body 1 during operation of the trolley using the double-layer insulating plates 342.

[0063] In one specific embodiment, the sliding assembly 12 is provided with two vehicle-mounted busbars 11. Using two vehicle-mounted busbars 11 can further improve the stability of the connection between the electrode clamping mechanism 2 and the busbar clamping mechanism 3.

[0064] The vehicle-mounted busbar clamping mechanism 31 includes: a first vehicle-mounted clamping body 311, a hydraulic cylinder 312, and a bracket 314;

[0065] In this embodiment, the vehicle busbar clamping mechanism 31 is provided with two first vehicle clamps 311, which are arranged in parallel. The two first vehicle clamps 311 are respectively connected to the output shafts of two hydraulic cylinders 312 to drive the two first vehicle clamps 311 to clamp or release the vehicle busbar 11. The two hydraulic cylinders 312 are respectively mounted on two brackets 314.

[0066] The vehicle busbar clamping mechanism 31 of this embodiment adopts a pair of first vehicle clamping bodies 311, hydraulic cylinders 312 and brackets 314, which clamp the vehicle busbar 11 through the two first vehicle clamping bodies 311, and the structure is simple and reliable.

[0067] In one specific embodiment, the vehicle busbar clamping mechanism 31 further includes: a cylinder base 313 and a bidirectional cylinder 315. The cylinder base 313 is disposed between two first vehicle clamps 311, and the bidirectional cylinder 315 is fixedly installed on the cylinder base 313. Both output shafts of the bidirectional cylinder 315 are connected to a second vehicle clamp 316.

[0068] The second vehicle-mounted clamp 316 and the first vehicle-mounted clamp 311 cooperate to clamp the two vehicle-mounted busbars 11.

[0069] In the complex busbar clamping mechanism 3, the position of one hydraulic cylinder 312 can be omitted, simplifying the mechanical mechanism and saving production costs.

[0070] Furthermore, the first vehicle-mounted clamp 311 is provided with a pressure plate 3111, a clamping part 3112, and a bending part 3113; the back of the pressure plate 3111 of the first vehicle-mounted clamp 3111 is connected to the oil cylinder 312, the front of the pressure plate 3111 is fixed to the clamping part 3112, and the lower end of the clamping part 3112 is connected to the bending part 3113. It is worth mentioning that the bending part 3113 will move together and deform during the clamping and releasing process of the first vehicle-mounted clamp 3111.

[0071] Please see Figure 6 and Figure 9The cylinder base 313 includes a base plate 3131 and support plates 3132. The base plate 3131 of the cylinder base 313 is placed on the fixing assembly 34, and several support plates 3132 form a cuboid structure of a sealing plate. An arc-shaped groove is left at the top for the double-headed cylinder 315 to be placed. This prevents displacement during the pushing process of the double-headed cylinder 315 and also provides support for the double-headed cylinder 315.

[0072] Please see Figure 6 and Figure 10 It should be noted that the bidirectional hydraulic cylinder 315 includes: cylinder body 3151 and push rod 3152, with push rod 3152 located at both ends of cylinder body 3151.

[0073] Please see Figure 6 and Figure 11 Because existing supports have problems such as poor mechanical strength and short service life, a new design was made to the structure of the support 314 in this embodiment.

[0074] In this embodiment, the bracket 314 includes: a side plate 3141, stiffening plates 3142, and connecting plates 3143; the side plate 3141 has a circular hole for fixing the hydraulic cylinder 312, and three stiffening plates 3142 are fixed on the back of the side plate 3141. The stiffening plates 3142 are arranged side by side with intervals. One end of the stiffening plate 3142 is connected to the side plate 3141, and the other end is fixed to the connecting plate 3143. The bracket 3144 has two connecting plates 3143. The connecting plates 3134 are arranged parallel to the side plate 3141. The two connecting plates 3141 are also arranged parallel to each other. The connecting plates 3141 are located in the lower half of the side plate 3141. The mechanical strength of the bracket 314 is greatly enhanced by the connection between several plates, and the service life is improved.

[0075] In this embodiment, the busbar clamping mechanism 3 adopts a bracket 314, which simultaneously supports the vehicle-mounted busbar clamping mechanism 31 and the main busbar clamping mechanism 32. The structure is simple, compact, and highly integrated.

[0076] In summary, please refer to Figures 1-9 Based on the above description of the power transmission vehicle, it should be noted that the power transmission vehicle has a working state and a release state.

[0077] When entering the working state, the motor drives the sliding seat 122 to move towards the conductive electrode. The vehicle busbar 11 and the electrode clamping mechanism 2 follow the sliding assembly 12 to move towards the conductive electrode. When the electrode clamping mechanism 2 moves to the preset position, the vehicle busbar 11 is also exactly at the center of the first vehicle clamp 311 of the vehicle busbar clamping mechanism 31. Then, the electrode clamping mechanism 2, the vehicle busbar clamping mechanism 31 and the main busbar clamping mechanism 32 act simultaneously. The electrode clamping mechanism 2 clamps the conductive electrode, the vehicle busbar clamping mechanism 31 clamps the vehicle busbar 11, and the main busbar clamping mechanism 32 clamps the power supply busbar. Then, the power supply busbar starts to supply power. The current is transmitted from the busbar clamping mechanism 3 to the vehicle busbar 11, and then from the vehicle busbar 11 to the electrode clamping mechanism 2, finally completing the power supply to the conductive electrode.

[0078] When the device is about to enter the release state, the electrode clamping mechanism 2, the vehicle busbar clamping mechanism 31, and the main busbar clamping mechanism 32 operate simultaneously. The electrode clamping mechanism 2 releases the conductive electrode, the vehicle busbar clamping mechanism 31 releases the vehicle busbar 11, and the main busbar clamping mechanism 32 releases the power supply busbar. The current transmission is disconnected, and the motor drives the sliding seat 122 to move in the opposite direction to the conductive electrode. The vehicle busbar 11 and the electrode clamping mechanism 2 follow the sliding assembly 12 to move in the opposite direction to the conductive electrode. When the electrode clamping mechanism 2 moves to the preset position, it stops, and the power supply vehicle begins to move to the next graphitization furnace.

[0079] 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 still fall within the protection scope of this invention.
