[0035] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings; In the following description, a large number of specific details are set forth in order to fully understand the present application; Based on the embodiments in the present application, those skilled in the art can make similar improvements without departing from the connotation of the present application, but all other embodiments obtained without creative labor are not allowed, therefore the present application is not limited by the specific implementation disclosed below.

[0036] In the description of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; It can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two elements, or it can be "driven connection", that is, through various suitable ways such as belt drive, gear drive or chain wheel drive to realize power connection. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific situation.

[0037] Please refer to Figure 1 In one embodiment, the first aspect of the present application provides a power supply car 100 for supplying power to a graphitization furnace to complete the graphitization process of the graphitization furnace.

[0038] When the graphitization furnace needs to be powered, the power supply car 100 moves along the track to the corresponding furnace position of the graphitization furnace, and then the power supply busbar 200 and the conductive electrode 300 of the graphitization furnace are connected to take power from the power supply busbar 200 and supply power to the graphitization furnace.

[0039] In the embodiment, the power supply busbar 200 is arranged directly above the power supply car 100, and the graphitization furnace is arranged on one side of the power supply car 100. In essence, the power supply busbar 200 can also be arranged on the side of the power supply car 100 opposite the graphitization furnace, or directly below the power supply car 100, which is not limited by the specific embodiment.

[0040] Please refer to Figure 2 In one embodiment, the power supply car 100 comprises a car body 10, a portal 20, a conductive mechanism 30 and a translation mechanism 50, the portal 20 is movably arranged on the car body 10; The translation mechanism 50 is fixedly arranged on the car body 10, and the translation mechanism 50 is used to drive the portal 20 to move forward and backward; The conductive mechanism 30 is suspended on the portal 20 and moves forward and backward under the driving of the portal 20.

[0041] On one hand, the vehicle body 10 serves as a carrier of the power supply vehicle 100, and is used to mount the portal 20 and the translation mechanism 50. On the other hand, the vehicle body 10 has a moving function, and drives the power supply vehicle 100 to move along the guide rail.

[0042] The conductive mechanism 30 is suspended by the portal 20, so that the conductive mechanism 30 only contacts the portal 20, and does not directly contact the vehicle body 10 and the translation mechanism 50. After the portal 20 is insulated, only the conductive mechanism 30 of the entire power supply vehicle 100 is electrified, which can prevent the staff from being electrified by accidentally touching the parts other than the conductive mechanism 30, and greatly improves the safety of the power supply vehicle 100. For example, the insulation treatment can be to arrange an insulating plate (not shown in the figure) at the contact position of the portal 20 and the conductive mechanism 30.

[0043] Specifically, the translation mechanism 50 can be a driving oil cylinder arranged in the front-rear direction of the power supply vehicle 100, and details are not repeated here.

[0044] Please refer to Figure 3 In one embodiment, the conductive mechanism 30 includes a conductive base 31, a busbar clamping mechanism 32, a stand column 33, and an electrode clamping mechanism 34. The busbar clamping mechanism 32 is arranged on the upper surface of the conductive base 31. The stand column 33 is suspended on the lower surface of the electrode clamping mechanism 34, and the electrode clamping mechanism 34 is fixed on the stand column 33.

[0045] In the prior art, the electrode clamping mechanism and the busbar clamping mechanism usually adopt a water-cooled copper bar to realize the electrical connection of the two. However, in actual work, the water-cooled copper bar is easy to bend and even break, and the electrical conductivity stability of the electrode clamping mechanism and the busbar clamping mechanism is poor.

[0046] The conductive mechanism 30 of the embodiment improves the stability of the electrical conductivity between the electrode clamping mechanism 34 and the busbar clamping mechanism 32 by installing the busbar clamping mechanism 32 on the conductive base 31 and indirectly installing the electrode clamping mechanism 34 on the conductive base 31 through the stand column 33. The conductive base 31 serves as a rigid conductor, which greatly improves the stability of the electrical conductivity between the electrode clamping mechanism 34 and the busbar clamping mechanism 32.

[0047] In addition, the electrode clamping mechanism 34 and the busbar clamping mechanism 32 are arranged on both sides of the conductive base 31, which reasonably utilizes the space.

[0048] Please refer to Figures 2-3 In one embodiment, the power supply vehicle 100 further includes a lifting mechanism 40, which is fixedly arranged on the upper surface of the conductive base 31 and connected with the busbar clamping mechanism 32, and is used to drive the busbar clamping mechanism 32 to lift.

[0049] The working principle of the conductive mechanism 30 is as follows: when power transmission is needed, the translation mechanism 50 drives the gantry 20 to move, the gantry 20 drives the conductive base 31 arranged on the gantry 20 to move, thereby driving the column 33 and the electrode clamping mechanism 34 of the conductive mechanism 30 to move, so that the electrode clamping mechanism 34 is in butt joint with the conductive electrode 300 of the graphitization furnace;

[0050] The lifting mechanism 40 drives the bus bar clamping mechanism 32 to move upward until the bus bar clamping mechanism 32 is in butt joint with the power transmission bus bar 200. When the power transmission trolley 100 ends power transmission, the translation mechanism 50 drives the conductive mechanism 30 to move away from the graphitization furnace, so that the electrode clamping mechanism 34 is separated from the conductive electrode 300 of the graphitization furnace.

[0051] The bus bar clamping mechanism 32 is separated from the power transmission bus bar 200 in a descending manner, which is more suitable for scenarios with small height restrictions. However, for scenarios with large height restrictions, the bus bar clamping mechanism 32 needs to be separated from the power transmission bus bar 200 in a side-moving manner.

[0052] The present application provides another specific embodiment, on the basis of the embodiment, the power transmission trolley 100 replaces the lifting mechanism 40 with a side pushing mechanism (not shown in the figure), which is connected with the bus bar clamping mechanism 32 to drive the bus bar clamping mechanism 32 to move linearly in the front-back direction.

[0053] When the power transmission trolley 100 needs to transmit power to the power transmission bus bar 200, the side pushing mechanism drives the bus bar clamping mechanism 32 to move linearly forward until the bus bar clamping mechanism 32 reaches the branch bus bar of the power transmission bus bar 200, and the bus bar clamping mechanism 32 clamps the power transmission bus bar 200. When the power transmission ends, the bus bar clamping mechanism releases the power transmission bus bar 200, and the side pushing mechanism drives the bus bar clamping mechanism 32 to move backward, so that the bus bar clamping mechanism 32 is separated from the branch bus bar of the power transmission bus bar 200, and the power transmission trolley 100 can continue to move along the track to the next furnace position of the graphitization furnace.

[0054] It should be noted that the side pushing structure needs to adaptively adjust the relative position of the power transmission trolley 100 and the power transmission bus bar 200.

[0055] The power transmission trolley 100 of the embodiment can be applied to scenarios with large height restrictions by using the side pushing mechanism to drive the bus bar clamping mechanism 32 to move forward and backward, i.e., the bus bar clamping mechanism 32 adopts a “side-in side-out” working mode.

[0056] Please refer to Figure 3 and Figure 4 In one embodiment, the conductive mechanism 30 includes a plurality of bus bar clamping mechanisms 32 arranged along the length direction of the conductive base 31. By using a plurality of bus bar clamping mechanisms 32 to butt joint the power transmission bus bar 200, the power transmission stability of the bus bar clamping mechanism 32 can be improved.

[0057] Further, the busbar clamping mechanism 32 comprises two clamping plates 323, two clamping cylinders 322, a cylinder support 321 and a support frame (not shown in the figure).

[0058] The two clamping plates 323 are oppositely arranged to clamp the busbar 200 together; the two clamping cylinders 322 are respectively arranged outside the two clamping plates 323, and the two clamping cylinders 322 are used to drive the two clamping plates 323 to move closer to or farther away from each other, so as to clamp or release the busbar 200.

[0059] Please refer to Figure 4 In an embodiment, the clamping cylinders 322 are fixedly connected with the support frame; the cylinder support 321 is fixedly arranged on the conductive base 31, and a strip-shaped hole extending in the vertical direction is formed on the conductive base 31 (not shown in the figure), and the clamping cylinders 322 are arranged in the strip-shaped hole. The clamping cylinders 322 can move within the range of the strip-shaped hole when the support frame is driven by the lifting mechanism 40. That is, the clamping cylinders 322 can move up and down relative to the cylinder support 321, so as to adapt to the lifting mechanism 40 driving the busbar clamping mechanism 32 to rise and fall.

[0060] Alternatively, the two clamping plates 323 are oppositely arranged; the two clamping cylinders 322 are respectively arranged outside the two clamping plates 323, and the two clamping cylinders 322 are used to drive the two clamping plates 323 to move closer to or farther away from each other, so as to clamp or release the busbar 200.

[0061] That is, the support frame and the clamping cylinders 322 are not fixed, and when the lifting mechanism 40 drives the busbar clamping mechanism 32 to rise and fall, only the support frame in the busbar clamping mechanism 32 is driven to move.

[0062] That is, the support frame and the clamping cylinders 322 are not fixed, and when the lifting mechanism 40 drives the busbar clamping mechanism 32 to rise and fall, only the support frame in the busbar clamping mechanism 32 is driven to move.

[0063] In the prior art, the applicant finds that the cylinder support 321 of the clamping type busbar clamp often deforms. Due to the deformation of the cylinder support 321, the position of the clamping cylinder 322 installed on the cylinder support 321 is offset, so that the two clamping plates 323 cannot clamp the busbar 200 together, affecting the stability of the power transmission vehicle 100.

[0064] The busbar clamping mechanism 32 provided in the application supports the cylinder body of the clamping oil cylinder 322 against the support frame, so that the support frame supports the clamping oil cylinder 322 to balance the counter-thrust of the power transmission busbar 200 to the oil cylinder, thereby reducing the local stress of the oil cylinder support 321, so that the oil cylinder support 321 is not prone to deformation, and the service life of the busbar clamping mechanism 32 is long.

[0065] Please refer to Figure 5 In one embodiment, the busbar clamping mechanism 32 further comprises a conductive sheet 324 and an insulating sheet 325, the conductive sheet 324 is arranged between the busbar clamping plate and the insulating sheet 325, and the conductive sheet 324 is connected with the conductive base 31.

[0066] Optionally, the conductive sheet 324 is fixed to the inner side of the clamping plate 323.

[0067] Among them, the conductive sheet 324 is at least partially configured to be flexible to adapt to the movement of the clamping plate 323 driven by the clamping oil cylinder 322; the insulating sheet 325 is used to insulate the clamping plate 323 from the conductive sheet 324 to cut off the power transmission path of the conductive sheet 324 and the clamping plate 323.

[0068] By arranging the conductive sheet 324 in the busbar clamping mechanism 32, connecting the conductive sheet 324 with the clamping plate 323 and the conductive base 31 respectively, and arranging the insulating sheet 325 between the clamping plate 323 and the conductive sheet 324, the electricity taken will be directly transmitted to the conductive base 31 by the conductive base 31, the power transmission path is unique and relatively short, and the power loss is small.

[0069] In one embodiment, the output shaft of the clamping oil cylinder 322 is pivoted with the clamping plate 323, and the clamping plate 323 can be flipped up and down relative to the clamping oil cylinder 322 to automatically adapt to the deformation of the power transmission busbar 200, thereby ensuring that the busbar clamping plate is tightly attached to the power transmission busbar 200.

[0070] Specifically, the output shaft of the clamping oil cylinder 322 is provided with a fisheye ball head, the back side of the clamping plate is provided with a rotating shaft matched with the fisheye ball head, and the fisheye bearing is sleeved on the rotating shaft of the back of the clamping plate to realize the pivoting of the clamping plate 323 to the clamping oil cylinder 322. The structure of the fisheye bearing and the rotating shaft is relatively simple, and the cooperation is relatively stable.

[0071] Please refer to Figure 3 and Figure 6 In one embodiment, the conductive mechanism 30 comprises: a plurality of vertical columns 33 arranged at intervals, and a plurality of electrode clamping mechanisms 34 are arranged on each vertical column 33.

[0072] Please refer to Figures 3-5In a second aspect of the present application, a busbar clamping mechanism 32 is provided for the power transmission vehicle 100 of any of the above embodiments. The busbar clamping mechanism 32 comprises:

[0073] two pairs of clamping plates 323 arranged oppositely for clamping the power transmission busbar 200;

[0074] two pairs of clamping cylinders 322 respectively connected with the pairs of clamping plates 323 for driving the pairs of clamping plates 323 to clamp or release the power transmission busbar 200;

[0076] a support frame, the clamping cylinders 322 abut against the support frame, and the output shafts of the clamping cylinders 322 are connected with the pairs of clamping plates 323.

[0077] The busbar clamping mechanism 32 provided by the present application balances the counter-thrust of the power transmission busbar 200 on the clamping cylinders 322 by arranging the support frame and abutting the clamping cylinders 322 against the support frame, so as to balance the counter-thrust of the power transmission busbar 200 on the clamping cylinders 322, thereby reducing the local stress on the cylinder support 321, preventing the cylinder support 321 from being deformed, and prolonging the service life of the busbar clamping mechanism 32.

[0078] In an embodiment, the output shafts of the clamping cylinders 322 are pivotally connected with the pairs of clamping plates 323, and the pairs of clamping plates 323 can be flipped up and down relative to the output shafts of the clamping cylinders 322.

[0079] Specifically, the output shafts of the clamping cylinders 322 are provided with fish-eye ball heads, the back sides of the pairs of clamping plates 323 are provided with shafts matched with the fish-eye ball heads, and fish-eye bearings are sleeved on the shafts on the back sides of the pairs of clamping plates 323, so as to realize the pivotal connection of the pairs of clamping plates 323 with the clamping cylinders 322. The fish-eye bearings and the shafts have relatively simple structures and relatively stable cooperation.

[0080] The pairs of clamping plates 323 are configured to be flipped up and down relative to the output shafts of the clamping cylinders 322, so as to adapt to the deformation of the power transmission busbar 200 and improve the stability of the connection between the busbar clamping mechanism 32 and the power transmission busbar 200.

[0081] In an embodiment, the inner side of the support frame is provided with a buffer pad (not shown in the figure), which is used to contact the clamping cylinders 322.

[0082] The buffer pad can avoid the direct rigid contact between the clamping cylinders 322 and the support frame, so as to balance the local stress on the support frame and prolong the service life of the support frame.

[0083] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art.
