[0038] The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0039] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict. The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, in which the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout.

[0040] The rectifier unit is a device for supplying power to a graphitization furnace. In the prior art, the electrode clamping mechanism includes a vehicle body, a transverse moving device, and electrode clamping device bus bar clamping devices that are electrically connected to each other. The electrode clamping device is arranged on the transverse moving device and moves forward and backward under the driving of the transverse moving device to be connected or separated from the conductive electrode of the graphitization furnace. The bus bar clamping device is independent of the electrode clamping device, and the two are connected by a water-cooled cable.

[0041] In the prior art, the electrode clamping device and the bus bar clamping device are arranged on the stand to improve the power supply stability of the rectifier unit. When the transverse moving device drives the electrode clamping device to move, the bus bar clamping device is arranged side by side with the power supply bus bar. During the operation of the bus bar clamping device, it will be interfered by the power supply bus bar, resulting in that the rectifier unit cannot supply power.

[0042] It should be noted that: the power supply bus bar extends along the movement direction of the rectifier unit. The bus bar clamping mechanism clamps the left and right sides of the power supply bus bar to realize the connection with the power supply bus bar. That is, when the transverse moving device drives the stand and the electrode clamping device arranged on the stand to move towards or away from the graphitization furnace, it will also drive the bus bar clamping device to move towards or away from the graphitization furnace synchronously.

[0043] In order to solve the interference problem of the bus bar clamping device, it is necessary to stagger the arrangement of the bus bar clamping device and configure an independent driving device for the bus bar clamping device, which occupies a large volume, has a complex structure, and has a high use cost.

[0044] Please refer to Figure 1 Some embodiments of the present application provide a rectifier unit 100, which includes a vehicle body 20 and a conductive mechanism 10 arranged on the vehicle body 20. The vehicle body 20 drives the rectifier unit 100 to a specified furnace position, and the conductive mechanism 10 is electrically connected to the conductive electrode and the power supply bus bar 200 of the graphitization furnace respectively to realize the power supply of the rectifier unit 100 to the graphitization furnace.

[0045] The power transmission busbar 200 is arranged directly below the rectifier set 100. When the rectifier set 100 is transmitting power, the conductive mechanism 10 contacts the power transmission busbar 200 to obtain power from the power transmission busbar 200.

[0046] Please refer to Figure 2 and Figure 3 , some embodiments of the present application provide a conductive mechanism 10 for a rectifier set, which can be a power transmission vehicle. The conductive mechanism 10 comprises a traversing device 11, a portal frame 12, a column 13, an electrode clamping device 14, and a busbar pressing device 15.

[0047] The portal frame 12 is fixedly arranged on the traversing device 11, and the traversing device 11 is used to drive the portal frame 12 to move towards or away from the graphitization furnace, so that the electrode clamping device 14 is in contact with or away from the conductive electrode of the graphitization furnace.

[0048] A plurality of columns 13 are suspended on the portal frame 12 and are arranged in a spaced manner along the direction of the crossbeam of the portal frame 12. The electrode clamping device 14 is arranged on each column 13, and is used to contact the conductive electrode of the graphitization furnace.

[0049] The busbar pressing device 15 is electrically connected with the electrode clamping device 14. In this embodiment, the busbar pressing device 15 is fixedly arranged on the column 13 and is arranged towards the power transmission busbar 200, and is used to contact the power transmission busbar 200.

[0050] The portal frame 12 is used to support the column 13, and is used to support the electrode clamping device 14 and the busbar pressing device 15 arranged on the column 13. The number and arrangement of the electrode clamping device 14 on the column 13 and the conductive electrode on the end wall of the graphitization furnace are one-to-one corresponding.

[0051] The rectifier set 100 of this embodiment contacts the conductive electrode of the graphitization furnace through the electrode clamping device 14 to transmit power, and contacts the power transmission busbar 200 through the busbar pressing device 15 to obtain power. The electrode clamping device 14 and the busbar pressing device 15 are electrically connected through the column 13, and the column 13 has strong conductivity and strong stability for water-cooled cable power transmission.

[0052] In other embodiments, the busbar pressing device 15 is directly installed on the vehicle body 20 or is installed on the bracket of the vehicle body 20, and a water-cooled cable is connected between the busbar pressing device 15 and the electrode clamping device 14.

[0053] Please refer to Figure 4 , in some embodiments of the present application, the busbar pressing device 15 comprises a driving member 151, a pressing plate 152, a flexible pad 153, and a connecting member 16.

[0054] The drive unit 151 is fixedly mounted at the bottom end of the column 13, and the output shaft of the drive unit 151 is vertically downward. The pressure plate 152 is connected to the output shaft of the drive unit 151, and the pressure plate 152 is driven to rise and fall by the drive unit 151. Specifically, when the rectifier unit 100 needs to supply power, the drive unit 151 drives the pressure plate 152 to descend until it abuts against the upper surface of the power supply busbar 200. When the rectifier unit 100 stops supplying power, the drive unit 151 drives the pressure plate 152 to rise until it separates from the power supply busbar 200, so that the rectifier unit 100 can move to the next graphitization furnace.

[0055] It should be noted that both the vehicle body 20 and the transverse movement device 11 are hollow. The busbar crimping device 15 passes through the vehicle body 20 and the transverse movement device 11. In this way, the transverse movement device 11 and the vehicle body 20 provide sufficient space for the pressure plate 152 of the busbar crimping device 15 to pass through the vehicle body 20 and the transverse movement device 11 and contact the power supply busbar 200.

[0056] The conductive mechanism 10 of this application is connected to the power supply busbar 200 (see [reference]) by means of a busbar crimping device 15. Figure 1 When the busbar crimping device 15 is connected, the driving component 151 of the busbar crimping device 15 drives the pressure plate 152 to rise and fall, which can complete the switching between the working state and the release state of the busbar crimping device 15 and the power supply busbar 200. The pressure plate 152 is not interfered with by the power supply busbar 200 during its movement. The conductive mechanism 10 has a compact structure and occupies a small volume.

[0057] Optionally, the drive component 151 can be a drive cylinder. By controlling the oil pressure of the drive cylinder, the position of the pressure plate 152 can be precisely adjusted so that the pressure plate 152 can abut against the power supply busbar 200 with appropriate pressure, thereby reducing the reverse thrust of the power supply busbar 200 on the rectifier unit 100 and preventing the rectifier unit 100 from being lifted and overturned.

[0058] Combination Figure 1 As is known, the power supply busbar 200 is located directly below the rectifier unit 100. Correspondingly, the busbar crimping device 15 is located at the bottom of the column 13. The busbar crimping device 15 is in contact with the upper surface of the power supply busbar 200.

[0059] In actual operation, the surface of the power supply busbar 200 is not flat. For example, the contact area between the power supply busbar 200 and the pressure plate 152 has some pits and protrusions. Therefore, if the pressure plate 152 directly presses against the power supply busbar 200, the contact between the pressure plate 152 and the power supply busbar 200 will be insufficient, which will seriously affect the power supply stability of the busbar crimping device 15.

[0060] Please see again Figure 4In some embodiments of the present application, the flexible pad 153 is laid on the side of the power feeding busbar 200, and the connecting piece 16 is arranged between the flexible pad 153 and the stand 13. The flexible pad 153 can be made of an aluminum sheet with certain flexibility.

[0061] When the pressing plate 152 is used to press the power feeding busbar 200, the flexible pad 153 first contacts the power feeding busbar 200 and deforms to adapt to the uneven surface of the power feeding busbar 200, so that the pressing plate 152 is more stable in connection with the power feeding busbar 200, and the power taking stability of the busbar pressing device 15 is good.

[0062] When the busbar pressing device 15 is switched between the working state and the release state, the connecting piece 16 deforms adaptively.

[0063] In the working state, the pressing plate 152 is driven downward by the driving piece 151 until the power feeding busbar 200 is pressed to take power from the power feeding busbar 200. In the release state, the pressing plate 152 is driven upward by the driving piece 151 until the pressing plate 152 is separated from the power feeding busbar 200.

[0064] The connecting piece 16 is composed of a plurality of flexible conductive strips that can be bent and twisted. The plurality of flexible conductive strips can deform adaptively according to different situations, further improving the working stability of the connecting piece 16.

[0065] The busbar pressing device 15 of the present embodiment uses the connecting piece 16 to make the pressing plate 152 conductive with the stand 13, so as to change the power transmission path and improve the power transmission efficiency.

[0066] It should be noted that in actual work, the power feeding busbar 200 is composed of two independent aluminum bars arranged side by side. The installation height of the two independent aluminum bars may have errors, causing unstable contact between the busbar pressing device 15 and the power feeding busbar 200. Even if the flexible pad 153 is arranged on the pressing plate 152, the height error still cannot be eliminated.

[0067] Please refer to Figure 5 and Figure 6 In order to solve the above problems, in some embodiments of the present application, the pressing plate 152 is provided with a plurality of pressing portions near the side of the power feeding busbar 200, and a gap is left between two adjacent pressing portions.

[0068] Specifically, the flexible pad 153 comprises a first crimping part 1531, a second crimping part 1532, a third crimping part 153 and a fourth crimping part 154, which are arranged in a square distribution, a first gap w1 is left between the first crimping part 1531 and the second crimping part 1532, a second gap w2 is left between the first crimping part 1531 and the third crimping part 153, a second gap w2 is left between the second crimping part 1532 and the fourth crimping part 154, and a first gap w1 is left between the third crimping part 153 and the fourth crimping part 154.

[0069] In the embodiment, the busbar crimping device 15 is provided with a plurality of flexible pads 153, and the flexible pads 153 are independently arranged, so that the flexible pads 153 can adapt to the installation height of the corresponding independent aluminum busbar, and the power taking stability of the busbar crimping device 15 is further improved.

[0070] Correspondingly, the connecting piece 16 is provided with two pieces, one of which connects the first crimping part 1531 and the third crimping part 153, and the other of which connects the second crimping part 1532 and the fourth crimping part 154.

[0071] Please refer to Figure 7 and Figure 8 In some embodiments of the application, the busbar crimping device 15 further comprises a cylinder mounting seat 155, the driving member 151 is mounted on the cylinder mounting seat 155, and the cylinder mounting seat 155 is mounted at the bottom of the column 13.

[0072] Specifically, the driving member 151 is provided with a flange with a hole, the cylinder mounting seat 155 is provided with a mounting hole, and the driving member 151 is mounted on the cylinder mounting seat 155 by means of a fastener penetrating the flange and the cylinder mounting seat 155.

[0073] In the embodiment, the driving member 151 is detachably mounted on the cylinder mounting seat 155, so that the driving member 151 can be replaced after being damaged, thereby reducing the use cost.

[0074] Further, the cylinder mounting seat 155 comprises a panel 1551, a side plate 1553 and a plurality of rib plates 1554, the side plate 1553 is connected to the two sides of the panel 1551 and perpendicular to the panel 1551, and the plurality of rib plates 1554 are fixed to the lower surface of the panel 1551. The cylinder mounting hole 1552 is formed in the panel 1551. The driving member 151 penetrates the cylinder mounting seat 155 and is fixed to the lower surface of the panel 1551 through the flange with a hole of the driving member 151.

[0075] Compared with mounting the driving member 151 on the lower surface of the panel 1551, the driving member 151 penetrates the cylinder mounting hole 1552, so that the installation of the driving member 151 is more compact.

[0076] The face plate 1551, the side plate 1553 and the rib plate 1554 of the oil cylinder mounting seat 155 can all be used as mounting surfaces to form multi-point mounting of the oil cylinder mounting seat 155, so as to improve the mounting stability of the oil cylinder mounting seat 155.

[0077] Please refer to Figures 1 to 4 The application also provides a rectifier unit 100, comprising a vehicle body 20 and the conductive mechanism 10 of any of the above embodiments arranged on the vehicle body 20.

[0078] The rectifier unit 100 of the application adopts the conductive mechanism 10 of any of the above embodiments, and the conductive mechanism 10 is connected to the power supply busbar 200 through the busbar pressing device 15. The driving member 151 of the busbar pressing device 15 drives the pressing plate 152 to move up and down, so as to switch the working state and the release state of the busbar pressing device 15 and the power supply busbar 200. The movement of the pressing plate 152 is not interfered by the power supply busbar 200. The conductive mechanism 10 has a compact structure and occupies a small volume. The overall structure of the rectifier unit 100 is compact.

[0079] Obviously, the above embodiments are only examples for clearly illustrating the application, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. It is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom still belong to the protection scope of the application.
