Detailed Implementation

[0032] 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.

[0033] 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.

[0034] Please see Figure 1 The first aspect of this application provides an electrode clamping device 10 for docking with the conductive electrode of a graphitization furnace.

[0035] The electrode clamping device 10 includes a drive cylinder 11, two clamping arms 12, and two clamping plates 13. One end of each clamping arm 12 is pivotally connected to the output shaft of the drive cylinder 11, and the other end is pivotally connected to the clamping plate 13. A drive unit is used to drive the clamping arm 12 to pivot, thereby causing the clamping plate 13 connected to the clamping arm 12 to pivot, so as to adapt to the lateral deformation of the conductive electrode and improve the stability of the connection between the electrode clamping device 10 and the conductive electrode.

[0036] An upper connecting rod 14 and a lower connecting rod 15 are pivotally connected between the two clamping arms 12, with the upper connecting rod 14 positioned above the lower connecting rod 15. The upper connecting rod 14 and the lower connecting rod 15 can drive one clamping arm 12 to move with the same amplitude as the other clamping arm 12, thereby maintaining the consistent size of the clamping jaws of the electrode clamping device 10 and ensuring a stable and reliable connection between the electrode clamping device 10 and the conductive electrode. The electrode clamping device 10 is in use.

[0037] When assembling the electrode clamping device 10, the clamping arm 12 is installed first, then the lower connecting rod 15 is installed on the lower clamping arm, and finally the clamping plate 13 is installed on the clamping arm 12. For ease of assembly, the assembly space for the clamping plate 13 is configured to be slightly larger than the size of the clamping plate 13. Due to the relatively large weight of the clamping plate 13, the center of gravity of the electrode clamping device 10 will shift towards its clamping jaws. This causes the electrode clamping device 10 to sag within the limited assembly space, affecting the stability of the connection between the electrode clamping device 10 and the conductive electrode of the graphitization furnace.

[0038] Please see Figure 2 To solve the above problems, the electrode clamping device 10 also includes two support components 16, which are fixedly disposed at both ends of the lower connecting rod 15 and abut against the clamping plate 13.

[0039] The electrode clamping device 10 of this application provides an upward support component 16 on the lower connecting rod 15 to counteract the downward movement of the clamping plate 13 caused by gravity. Under the premise that there is an assembly gap to facilitate assembly, the position of the clamping plate 13 is stable and reliable, and the connection between the electrode clamping device 10 and the conductive electrode of the graphitization furnace is stable and reliable.

[0040] Please see Figure 3 and Figure 4 In one specific embodiment, the support assembly 16 includes a sleeve 161 and a ball bearing 162 rotatably disposed within the sleeve 161. The ball bearing 162 protrudes from one end opening of the sleeve 161 and contacts the lower side wall of the clamping plate 13.

[0041] In this embodiment, by providing ball bearings 162 on the support assembly 16, the ball bearings 162 roll when they come into contact with the clamping plate 13, thereby reducing the friction between the support assembly 16 and the clamping plate 13 and improving the service life of the electrode clamping device 10.

[0042] The electrode clamping device 10 has a working state and a released state, and can switch between the two states. In the working state, the drive cylinder 11 drives the two clamping arms 12 to move closer to each other, and the two clamping arms 12 drive the two clamping plates 13 to clamp the conductive electrode. In the released state, the drive cylinder 11 drives the two clamping arms 12 to move away from each other, and the two clamping arms drive the clamping plates 13 to move away from the conductive electrode.

[0043] It should be noted that during the switching between the working state and the release state of the electrode clamping device 10, the clamping plate 13 needs to move relative to the support component 16, and there is a certain amount of friction between the two.

[0044] In another alternative embodiment, the support component 16 is a support rod, which can still support the clamping plate 13, making the position of the clamping plate 13 more stable.

[0045] Compared to the support rod solution, the combination of sleeve 161 and ball 162 has less friction with the clamping plate 13, and the operation is more stable, which can prevent the paint on the lower surface of the clamping plate 13 from being scratched.

[0046] Preferably, the end of the support rod that contacts the clamping plate 13 is configured to be spherical and smooth. This reduces friction between the support rod and the clamping plate 13, extending the service life of the electrode clamping device 10.

[0047] In one specific embodiment, the two ends of the lower connecting rod 15 are bent to form extensions 151, and the sleeve 161 of the support assembly 16 is mounted on the extensions 151. The support assembly 16 is located below the clamping plate 13. The two extensions 151 extend in the same direction.

[0048] The lower connecting rod 15 has an installation hole that matches the sleeve 161. The sleeve 161 is inserted into the installation hole, and the installation of the sleeve 161 is stable and reliable.

[0049] Of course, the sleeve 161 can also be fixed by means of mounting grooves, clamping, welding and other processes.

[0050] One end of the clamping plate 13 is hinged to the clamping arm 12, and the projection of the support assembly 16 onto the clamping plate 13 is approximately located at 1 / 3 to 2 / 3 of the lower clamping arm of the clamping plate 13. For example, the support assembly 16 is located exactly on the central axis of the clamping plate 13.

[0051] In this way, the relative displacement between the clamping arm 12 and the support assembly 16 is small, the support assembly 16 provides good support for the clamping arm 12, the friction loss is small, and the service life of the electrode clamping device 10 is long.

[0052] Please see Figure 5 A second aspect of this application provides a conductive mechanism for a rectifier unit. The rectifier unit may be an electric transmission vehicle.

[0053] The conductive mechanism includes: a column 20, a gantry 30, a busbar clamping mechanism, a sliding mechanism 50, and an electrode clamping device 10 as described in any of the above embodiments.

[0054] The gantry 30 is mounted on the sliding mechanism 50 and moves back and forth in a straight line under the drive of the sliding mechanism 50; the column 20 is suspended on the gantry 30, the electrode clamping device 10 is mounted on the column 20, and the busbar connecting mechanism 40 is mounted on the column 20.

[0055] The conductive mechanism of this application has a support component 16 on its electrode clamping device 10. The support component 16 provides upward support to the clamping plate 13 to counteract the downward movement of the clamping plate 13 caused by gravity. Under the premise of having an assembly gap to facilitate assembly, the position of the clamping plate 13 is stable and reliable. The connection between the electrode clamping device 10 and the conductive electrode of the graphitization furnace is stable and reliable, and the working stability of the conductive mechanism is strong.

[0056] Please see Figure 6 In a third aspect, this application provides a power transmission vehicle, comprising: a vehicle body and a conductive mechanism according to any of the above embodiments, wherein the conductive mechanism is disposed on the vehicle body.

[0057] The electric transmission vehicle of this application uses an electrode clamping device 10 with a support component 16 in its conductive mechanism. The support component 16 provides upward support to the clamping plate 13 to counteract the downward movement of the clamping plate 13 caused by gravity. Under the premise of having an assembly gap to facilitate assembly, the position of the clamping plate 13 is stable and reliable. The connection between the electrode clamping device 10 and the conductive electrode of the graphitization furnace is stable and reliable, and the operation of the electric transmission vehicle is stable and reliable.

[0058] 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.
