The power transmission car is provided with electrode clamps and busbar clamps electrically connected to each other. During the power transmission process, the electrode clamps are clamped to the conductive electrodes of the graphitization furnace, and the busbar clamps are clamped to the power transmission busbar to support the production of the graphitization furnace.

[0003] In the prior art, the busbar clamp is movably arranged on a base, and the power transmission vehicle adopts two driving mechanisms to drive the busbar clamping plates to open and close from both sides of the busbar clamp.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figures 1 to 6In one embodiment, in order to solve the problem of unstable docking and short service life of the busbar clamp 20 and the power transmission busbar (not shown), the present application proposes a busbar clamping mechanism 100, which includes: a conductive frame 10, a busbar clamp 20 and a driving mechanism 30, the busbar clamp 20 is arranged on the conductive frame 10, the busbar clamp 20 includes a busbar clamp plate 21 and a conductive sheet 22, the conductive sheet 22 is arranged on the inner side wall of the busbar clamp plate 21, at least a part of the conductive sheet 22 is elastic, and the driving mechanism 30 is arranged on the outer side of the busbar clamp plate 21; wherein the busbar clamp plate 21 and the conductive sheet 22 are both arranged in two, and the driving mechanism 30 is used to drive the two busbar clamp plates 21 to move closer to or away from each other, so as to drive the two conductive sheets 22 to move closer to or away from each other. Compared with the prior art, the busbar clamping mechanism 100 provided by the present invention has the following advantages: when the busbar clamp 20 and the power transmission busbar are in the process of docking, if there is some deviation in the busbar clamp 20, the elastic conductive sheet 22 undergoes elastic deformation to adapt to the position of the power transmission busbar, so that the busbar clamp 20 and the power transmission busbar are not affected by internal forces during the docking process, thereby increasing the service life of the busbar clamp 20.

[0038] In one embodiment, the conductive sheet 22 includes: a clamping portion 221, an elastic portion 222 and a connecting portion 223, and the two ends of the elastic portion 222 are respectively connected to the clamping portion 221 and the connecting portion 223. The elastic portion 222 is elastic and can fine-tune the shape of the conductive sheet 22. The clamping portion 221 is a rigid structure and can increase the contact area between the conductive sheet 22 and the branch busbar; the connecting portion 223 is also a rigid structure, so that the operator can install the conductive sheet 22 on the column 40.

[0039] In one embodiment, the busbar clamping mechanism 100 also includes a column 40, which is fixedly suspended on the conductive frame 10, the busbar clamp 20 is arranged on the column 40, and the conductive sheet 22 is connected to the column 40; the bottom end of the column 40 forms a plurality of overlapping welding sheets 41 toward the side, and the overlapping welding sheets 41 constitute the base of the busbar clamp 20 (not shown in the figure), and the connection area between the overlapping welding sheets 41 and the column 40 is the sum of the side wall areas of the welding sheets 41, and the connection area is much larger than the contact area between the column 40 and the entire copper column, so the power loss is small and the use cost is low.

[0040] Of course, the column 40 and the base can also be configured to be integrally formed, and are not limited to the specific limitations of the specific implementation method.

[0041] In one embodiment, the busbar clamp 20 adopts a clamp-type busbar clamp plate 21. That is, a driving mechanism 30 and a serial oil cylinder 23 are respectively provided on both sides of the busbar clamp plate 21 of a part of the busbar clamps 20. The clamping and releasing of the busbar 20 are controlled by controlling the oil pressure of the driving mechanism 30 and the serial oil cylinder 23. The serial oil cylinder 23 is provided on both sides of the other part of the busbar clamps 20, and the clamping and releasing of the busbar clamp 20 are controlled by the oil pressure of the two serial oil cylinders 23.

[0042] In conventional transmission vehicles, the double-clip busbar clamps all have two jacking cylinders. The design of the two jacking cylinders makes the structure of the busbar clamp 20 too complicated and the use cost too high.

[0043] The busbar clamping mechanism 100 of some embodiments of the present application adopts a pair of clamped busbar clamps 20, and a series cylinder 23 is connected between two adjacent busbar clamps 20, that is, the two adjacent busbar clamps 20 share the series cylinder 23. In this way, in this embodiment, the overall structure of the busbar clamping mechanism 100 can be simplified and the cost of use can be reduced.

[0044] In one embodiment, the conductive frame 10 includes: a conductive base 11, a conductive connecting beam 12 and a conductive top seat 13, the conductive connecting beam 12 is arranged on the conductive base 11, and the conductive top seat 13 is arranged on the conductive connecting beam 12; the conductive top seat 13 extends downward to set a plurality of groups of mounting plates 131 arranged from left to right, and a group of mounting plates 131 is fixedly set on both sides of the column 40 to increase the contact area between the conductive connecting beam 13 and the column 40, which can improve the stability of the connection between the two, and can also reduce the contact resistance to avoid overheating.

[0045] In one embodiment, the conductive base 11 is a hollow frame, and a plurality of groups of mounting posts 111 arranged from left to right are provided in the conductive base 11, and a busbar clamp 21 is pivotally connected to a group of mounting posts 111. That is, the busbar clamp 20 can rotate with the mounting posts 111 as an axis, so as to adaptively deflect when the busbar clamp 20 is inserted downward, so as to improve the stability of the busbar clamp 20 docking with the power transmission busbar (not shown), and increase the service life of the busbar clamp.

[0046] Furthermore, the busbar clamp 20 also includes a busbar clamp oil cylinder 24 , and the busbar clamp oil cylinder 24 is connected to the conductive base 11 .

[0047] See also Figure 6 In one embodiment, the present application also provides a power transmission vehicle 50, which includes: a vehicle body 51, a gantry 52, a busbar clamping mechanism 100, a lifting mechanism 53 and a translation mechanism 54. The gantry 52 is movably arranged on the vehicle body 51, and is configured to move forward and backward under the drive of the translation mechanism 54; the lifting mechanism 53 is fixedly arranged on the gantry 52; the busbar clamping mechanism 100 is connected to the lifting mechanism 53, and rises and falls under the driving action of the lifting mechanism 53.

[0048] Specifically, the power transmission vehicle 50 has a power transmission state and an idle state, and can switch between the power transmission state and the idle state. When switched to the power transmission state, the translation mechanism 54 drives the gantry 52 to move forward, and the lifting mechanism 53 drives the busbar clamping mechanism 100 to descend until the busbar clamping mechanism 100 is respectively docked with the power transmission busbar of the graphitization furnace; when switched to the idle state, the translation mechanism 44 drives the gantry 42 to move backward, and the lifting mechanism 43 drives the busbar clamping mechanism 100 to rise until the busbar clamping mechanism 100 is respectively separated from the power transmission busbar.

[0049] The gantry 42 moves forwards so that the power transmission vehicle 40 moves closer to the graphitization furnace, and the gantry 42 moves backwards so that the power transmission vehicle 40 moves away from the conductive electrode.

[0050] In summary, compared with the prior art, the busbar clamping mechanism 100 provided by the present invention has a structure that, when the busbar clamp 20 and the power transmission busbar are in the process of docking, if there is some deviation in the busbar clamp 20, the elastic conductive sheet 22 undergoes elastic deformation to adapt to the position of the power transmission busbar, so that during the docking process, the busbar clamp 20 and the power transmission busbar are not affected by internal forces, thereby increasing the service life of the busbar clamp 20.

[0051] Obviously, the above embodiments are only examples for the detailed description of the present invention, and are not intended to limit the implementation methods. The present invention can also be implemented in many other ways different from those described herein. Although the implementation methods of the present invention are described in conjunction with the accompanying drawings, it is clear to those skilled in the art that other different forms of modifications and variations can be made based on the above description, and such modifications and variations still fall within the scope of protection defined by the appended claims of the present invention.
