Detailed Implementation

[0034] 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.

[0035] 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.

[0036] Please see Figures 1-4 In some embodiments of this utility model, an electrode clamping device 10 is provided, which is used to connect to the conductive electrode of the graphitization furnace. That is, the clamping jaw of the electrode clamping device 10 extends into the conductive electrode and is abutted by the conductive electrode to clamp the conductive electrode.

[0037] Please see Figure 1 and Figure 2 The electrode clamping device 10 of this embodiment includes: a driving member 11, two clamping arms 12, and two clamping plates 13. One end of the two clamping arms 12 is pivotally connected to the driving member 11 and swings left and right under the drive of the driving member 11; the two clamping plates 13 are respectively pivotally connected to the two clamping arms 12.

[0038] The clamping arm 12 is provided with a limiting component, which is located near the clamping plate 13 to restrict the clamping plate 13 from continuing to pivot in the same direction.

[0039] The electrode clamping device 10 of this utility model has a limiting component set in the clamping arm 12. The limiting component is configured to restrict the clamping plate 13 from flipping in the same direction, so that the clamping opening is large enough to allow the conductive electrode to pass through. The clamping plate 13 can stably clamp the conductive electrode on both sides, thereby improving the working stability of the electrode clamping device 10.

[0040] The driving component 11 can be a hydraulic cylinder, which precisely controls the movement of the clamping arms 12 by adjusting the hydraulic pressure of the hydraulic cylinder. The two clamping arms 12 are pivotally connected to the driving component 11 and swing left and right under the drive of the driving component 11 to adapt to the irregular deformation of the conductive electrode in the left and right direction during the clamping process, thereby improving the stability of the electrode clamping device 10 and the conductive electrode.

[0041] Please see Figure 3 In some specific embodiments, the clamping arm 12 includes a lower clamping part 121 and an upper clamping part 122, and the limiting component includes a first limiting part 141 and a second limiting part 142. The first limiting part 141 is disposed on the lower clamping part 121, and the second limiting part 142 is disposed on the upper clamping part 122.

[0042] The first limiting part 141 is integrally formed with the lower clamping part 121, and the upper clamping part 122 is integrally formed with the second limiting part 142, which can reduce the difficulty and workload of assembly. Of course, fixed connection, detachable connection and other assembly methods can also be adopted.

[0043] The upper clamping portion 122 and the lower clamping portion 121 serve as mounting bases for the first limiting portion 141 and the second limiting portion 142, respectively. In this embodiment, the pivot point between the clamping plate 13 and the clamping arm 12 is approximately located at the center of the clamping plate 13. The clamping plate 13 is divided into a front side and a rear side based on the pivot point, and both the first limiting portion 141 and the second limiting portion 142 are located near the rear side of the clamping plate 13.

[0044] When either of the two clamping plates 13 pivots inward, the clamping opening gradually narrows, meaning the front sides of the two clamping plates 13 gradually move closer together, and the rear sides of the two clamping plates 13 gradually move further apart. When the clamping plate 13 rotates to the point where the clamping opening cannot accommodate the conductive electrode, the first limiting part 141 and the second limiting part 142 respectively abut against the rear side of the electrode clamping plate 13 to restrict the electrode clamping plate 13 from continuing to pivot inward.

[0045] The first limiting part 141 and the second limiting part 142 are used together to restrict the rotation of the clamping plate 13, so that the force on the clamping plate 13 is more even and the service life of the clamping plate 13 is longer.

[0046] Of course, in other embodiments, only the first limiting part 141 and the second limiting part 142 may be installed, which saves materials and simplifies the structure while still providing the limiting function.

[0047] Please see Figure 4 In some embodiments of this utility model, the first limiting part 141 includes: a limiting baffle 1411 and a positioning screw 1412 disposed on the limiting baffle 1411, with one end of the positioning screw 1412 facing the clamping plate 13.

[0048] By controlling the installation position of the positioning screw 1412 on the limiting baffle 1411, the contact position between the first limiting part 141 and the clamping plate 13 can be effectively controlled, thereby adjusting the degree of inward rotation of the clamping plate 13, making the limiting of the clamping plate 13 more flexible.

[0049] Specifically, when the limiting degree is insufficient, the extension of the positioning screw 1412 can be increased. Conversely, when the limiting degree is excessive, the positioning screw 1412 can be retracted, and the extension of the positioning screw 1412 can be shortened.

[0050] Of course, the positioning screw 1412 is movably mounted on the limiting baffle 1411, so that the positioning screw 1412 can be screwed in and out relative to the limiting baffle 1411, making operation flexible and convenient. Of course, the second limiting part 142 can also be configured as the limiting baffle 1411 and the positioning screw 1412 mounted on the limiting baffle 1411, which will not be described in detail here.

[0051] Please refer to it again. Figure 3 A first connecting shaft 123 is connected between the upper clamping part 122 and the lower clamping part 121, and the clamping plate 13 is pivotally mounted on the first connecting shaft 123.

[0052] The clamping plate 13 has a mounting hole (not shown) that is adapted to the first connecting shaft 123, and the positioning shaft passes through the mounting hole of the clamping plate 13. The contact position between the clamping plate 13 and the connecting shaft is roughly located at the central axis of the clamping plate 13.

[0053] The first connecting shaft 123 has a simple and reliable structure, and can smoothly realize the pivoting of the clamping plate 13 relative to the clamping arm 12.

[0054] In one specific embodiment, a second connecting shaft 124 is connected between the upper clamping part 122 and the lower clamping part 121. The second connecting shaft 124 and the first connecting shaft 123 are spaced apart from each other along the direction of extension of the clamping arm 12. The first limiting part 141 and the second limiting part 142 are disposed adjacent to the second connecting shaft 124.

[0055] By setting a second connecting shaft 124, the upper clamping part 122 and the lower clamping part 121 can be connected, which improves the mechanical strength of the clamping arm 12 and enables the upper connecting rod 15 to be pivotally connected to the clamping arm 12 and the lower connecting rod 16 to be pivotally connected to the clamping arm 12.

[0056] In one specific embodiment, the upper clamp 122 and the lower clamp 121 are provided with two oppositely arranged mounting bushings 125 at the ends near the drive member 11.

[0057] The output shaft of the drive component 11 is fixed with a positioning post. Two mounting bushings 125 are respectively fitted onto the positioning post from both ends, which can effectively realize the pivot connection between the drive component 11 and the clamping arm 12.

[0058] Please see again Figure 1 and Figure 2 An upper connecting rod 15 and a lower connecting rod 16 are pivotally connected between the two clamping arms. The upper connecting rod 15 and the lower connecting rod 16, as synchronous driving components 11 of the transmission arm, transmit kinetic energy to the two clamping arms 12, so that the movement amplitude of the clamping arms 12 remains basically consistent, making the operation of the electrode clamping device 10 more stable.

[0059] Please see Figure 5 Some embodiments of this utility model provide a conductive mechanism 100, including: a column 20, a suspension device 30, a busbar clamping device, and an electrode clamping device 10 of any of the above. The electrode clamping device 10 is disposed on the column 20 and suspended on the column 20. The busbar clamping device is electrically connected to the electrode clamping device 10.

[0060] In this embodiment, a main busbar 40 is connected between the electrode clamping device 10 and the busbar clamping device. The main busbar 40 is a rigid conductor, which can overcome the disadvantage of water-cooled cables being prone to bending and breakage, and has strong working stability. Correspondingly, a suspension device 30 is provided on the column 20 to fix the main busbar 40.

[0061] The conductive mechanism 100 of this application employs an electrode clamping device 10 with a limiting component. By setting the limiting component on the clamping arm 12, the limiting component is configured to restrict the clamping plate 13 from flipping in the same direction, so that the clamping opening size allows the conductive electrode to pass through. The clamping plate 13 can stably clamp on both sides of the conductive electrode, thereby improving the working stability of the electrode clamping device 10 and the working stability of the conductive mechanism 100.

[0062] Please see Figure 6Some embodiments of this utility model provide a power transmission vehicle, which includes: a vehicle body 200 and a conductive mechanism 100 of any of the above embodiments disposed on the vehicle body 200.

[0063] In this embodiment, the power transmission vehicle employs an electrode clamping device 10 with a limiting component. By setting the limiting component on the clamping arm 12, the limiting component is configured to restrict the clamping plate 13 from rotating in the same direction, so that the clamping opening size allows the conductive electrode to pass through. The clamping plate 13 can stably clamp the two sides of the conductive electrode, improving the working stability of the electrode clamping device 10, thereby improving the stability of the power transmission vehicle docking with the graphitization furnace.

[0064] 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.
