[0038] In the traditional power supply trolley 50, the electrode clamping mechanism 30 and the busbar clamping mechanism 40 are independently arranged, see CN202310255343.1. That is, the power supply trolley 50 needs to use a special structure to install the electrode clamping mechanism 30 and the busbar clamping mechanism 40 respectively. However, the structure of such power supply trolley 50 is complex, the installation is cumbersome, and the use cost is high.

[0039] Please refer to Figures 1 to 8 In one embodiment, in order to solve the problem of complex structure, cumbersome installation and high use cost of the power supply trolley 50, the application provides a conductive mechanism 100, which comprises: a conductive frame body 10, a column 20, an electrode clamping mechanism 30 and a busbar clamping mechanism 40;The column 20 is arranged on the conductive frame body 10, and the electrode clamping mechanism 30 and the busbar clamping mechanism 40 are arranged on the same column 20.

[0040] Among them, the conductive mechanism 100 includes three columns 20 arranged at intervals, and three electrode clamping mechanisms 30 are arranged along the length direction of each column 20 to form a 3*3 square array to correspond to the distribution of the conductive electrode on the graphitization furnace. The lower end of each column 20 is provided with a busbar clamping mechanism 40, and the busbar clamping mechanism 40 is used to clamp the power supply busbar laid on the ground.

[0041] By arranging the electrode clamping mechanism 30 and the busbar clamping mechanism 40 on the same column 20, the busbar clamping mechanism 40 and the electrode clamping mechanism 30 are electrically connected through the column 20, the power transmission path is short, the power loss is small, and the structure is more simple and compact, and the assembly difficulty is lower.

[0042] Please refer to Figures 1 to 3In one embodiment, the conductive frame body 10 comprises: a conductive base 11, a conductive connecting beam 12 and a conductive top base 13, the conductive connecting beam 12 is arranged on the conductive base 11, and the conductive top base 11 is arranged on the conductive connecting beam 12; the conductive top base 13 extends downward to arrange a plurality of groups of mounting pieces 131 arranged from left to right, and one group of mounting pieces 131 is fixedly arranged on both sides of the stand column 20, so as to increase the contact area of the conductive connecting beam 12 and the stand column 20, improve the stability of the connection between the two, and reduce the contact resistance to avoid overheating.

[0043] Please refer to Figures 1 to 3 In one embodiment, the conductive base 11 is a hollow frame body, and a plurality of groups of mounting columns 111 arranged from left to right are arranged in the conductive base 11, and a busbar clamping mechanism 40 is pivoted to one group of mounting columns 111. That is, the busbar clamping mechanism 40 can rotate around the mounting column 111 as the shaft to adaptively deflect when it is inserted downward, so as to improve the stability of the busbar clamping mechanism 40 and the power supply busbar.

[0044] Please refer to Figure 6 In one embodiment, the bottom end of the stand column 20 forms a plurality of overlapping welding pieces 21 to the side, and the overlapping welding pieces 21 constitute the base (not shown in the figure) of the busbar clamping mechanism 40. The connection area of the overlapping welding pieces 21 and the stand column 20 is the sum of the side wall areas of the welding pieces 21. The connection area is much larger than the contact area of the stand column 20 and the whole copper column, the electrical loss is small, and the use cost is low.

[0045] Of course, the stand column 20 and the base can also be integrally formed, which is not limited to the specific limitation of the specific embodiment.

[0046] Please refer to Figure 4 and Figure 5 In one embodiment, the electrode clamping mechanism 30 comprises: an electrode clamping oil cylinder 31, a conductive connecting piece 34, two clamping arms 32 and two electrode clamping plates 33, one end of each clamping arm 32 is connected with the electrode clamping oil cylinder 31, the other end is pivoted to the electrode clamping plate 33, and the conductive connecting piece 34 is connected with the stand column 20 and the electrode clamping plate 33 respectively.

[0047] Further, the electrode clamping oil cylinder 31 is used to provide power for the deflection of the clamping arm 32, and is controlled by the oil pressure outside to make the electrode clamping mechanism 30 in a clamping state or a release state. When the electrode clamping mechanism 30 is in the clamping state, the electrode clamping oil cylinder 31 drives the clamping arms to move close to each other, drives the two electrode clamping plates 33 to move close to each other, so as to stably clamp the conductive electrode; when the electrode clamping mechanism 30 is in the release state, the electrode clamping oil cylinder 31 drives the clamping arms 32 to move away from each other, so as to control the two electrode clamps to be arranged away from each other.

[0048] Further, the clamping arm 32 can be pivoted in the horizontal direction relative to the electrode clamping cylinder 31, and the electrode clamping plate 33 can be pivoted in the horizontal direction under the drive of the clamping arm 32.

[0049] Please refer to Figure 5 In an embodiment, the electrode clamping plate 33 comprises a plate body 331 and an insulating pad 332 arranged on the inner side of the plate body 331. The conductive connecting piece 34 is arranged on the insulating pad 332. The insulating pad 332 plays an insulating role and can change the power transmission path of the power transmission vehicle 50 to improve the power transmission efficiency.

[0050] Specifically, the current transmitted by the busbar clamping mechanism 40 is transmitted to the column 20, and then transmitted to the conductive connecting piece 34 of the electrode clamping mechanism 30 through the column 20, and finally transmitted to the conductive electrode of the graphitization furnace through the conductive connecting piece 34. In essence, the clamping arm 32 and the electrode clamping cylinder 31 of the electrode clamping mechanism 30 do not enter the power transmission path.

[0051] In addition, the back side of the plate body 331 is provided with reinforcing ribs (not shown in the figure). The reinforcing ribs are arranged in a cross shape to form a checkered pattern, which can increase the mechanical strength of the plate body 331 itself and improve the service life of the electrode clamping plate 33.

[0052] Please refer to Figures 6 to 7 In an embodiment, the busbar clamping mechanism 40 adopts a clamping type busbar clamp. That is, the two sides of the busbar clamping plate 42 of a part of the busbar clamping mechanism 40 are respectively provided with a busbar clamping cylinder 41 and a series cylinder 44. The clamping and loosening of the busbar clamping mechanism 40 are controlled by controlling the oil pressure of the busbar clamping cylinder 41 and the series cylinder 44. The two sides of another part of the busbar clamping mechanism 40 are both provided with a series cylinder 44, and the clamping and loosening of the busbar clamping mechanism 40 are controlled by the oil pressure of the two series cylinders 44.

[0053] In actual work, the busbar clamping mechanism 40 has two push oil cylinders, but the two push oil cylinders are only used for this busbar clamping mechanism 40. In this way, the structure of the busbar clamping mechanism 40 is too complex, and the use cost is too high.

[0054] In some embodiments of the present application, the busbar clamping mechanism 40 adopts a clamping type busbar clamp, and a series cylinder 44 is connected between adjacent two busbar clamping mechanisms 40, that is, the adjacent two busbar clamping mechanisms 40 share the series cylinder 44. In this embodiment, the overall structure of the busbar clamping mechanism 40 can be simplified, and the use cost can be reduced.

[0055] Please refer to Figure 7 In an embodiment, the busbar clamping mechanism 40 comprises a busbar clamping plate 42, a conductive sheet 43, and a busbar clamping cylinder 41. The busbar clamping cylinder 41 is fixedly arranged on the conductive base 11, and the series cylinder 44 is connected between adjacent two busbar clamping mechanisms 40.

[0056] Further, the embodiment has three busbar clamping mechanisms 40, arranged from left to right as the first busbar clamping mechanism, the second busbar clamping mechanism and the third busbar clamping mechanism. The left side of the first busbar clamping mechanism is provided with a busbar clamping cylinder 41, the first busbar clamping mechanism and the second busbar clamping mechanism are connected by a series cylinder 44, the second busbar clamping mechanism and the third busbar clamping mechanism are connected by a series cylinder 44, and the right side of the third busbar clamping mechanism is provided with another busbar clamping cylinder 344.

[0057] That is, one busbar clamping plate 42 of the busbar clamping mechanism 40 is connected with the busbar clamping cylinder 41, and the other busbar clamping plate 42 is connected with the series cylinder 44. Alternatively, both busbar clamping plates 42 are connected with the series cylinder 44.

[0058] The conductive sheet 43 is fixedly arranged on the inner side wall of the busbar clamping plate 42 and is fixedly arranged on the stand column 20. When the power car 50 is ready to supply power, the busbar clamping cylinder 41 and the series cylinder 44 are controlled to make the two busbar clamping plates 42 of the busbar clamping mechanism 40 close to each other until the conductive sheet 43 arranged on the inner side wall of the busbar clamping plate 42 tightly presses the power supply busbar. When the power car 50 ends, the busbar clamping cylinder 41 and the series cylinder 44 are controlled to make the two busbar clamping plates 42 of the busbar clamping mechanism 40 away from each other until the busbar clamping mechanism 40 can be taken out from the power supply busbar.

[0059] Please refer to Figure 8 The application also provides a power supply car 50, which comprises a car body 51, a portal 52, a conductive mechanism 100, a lifting mechanism 53 and a translation mechanism 54. The portal 52 is movably arranged on the car 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 portal 52. The conductive mechanism 100 is connected with the lifting mechanism 53 and is driven to rise and fall by the lifting mechanism 53.

[0060] Specifically, the power supply car 50 has a power supply state and an idle state, and can switch between the power supply state and the idle state. When switched to the power supply state, the translation mechanism 54 drives the portal 52 to move forward, and the lifting mechanism 53 drives the conductive mechanism 100 to descend until the conductive mechanism 100 is respectively connected with the conductive electrode of the graphitization furnace and the power supply busbar. When switched to the idle state, the translation mechanism 54 drives the portal 52 to move backward, and the lifting mechanism 53 drives the conductive mechanism 100 to rise until the conductive mechanism 100 is separated from the conductive electrode of the graphitization furnace and the power supply busbar.

[0061] Wherein, the forward movement of the portal 52 is the movement of the power supply car 50 to the graphitization furnace, and the backward movement of the portal 52 is the movement of the power supply car 50 away from the conductive electrode.

[0062] Compared with the prior art, the conductive mechanism 100 provided by the utility model, through fixedly arranging the stand column 20 on the conductive frame body 10, and arranging the busbar clamping mechanism 40 and the electrode clamping mechanism 30 on the same stand column 20, the busbar clamping mechanism 40 and the electrode clamping mechanism 30 are electrically connected through the stand column 20, the power transmission path is short, the electric loss is small, and the structure is more simple and compact, and the assembly difficulty is lower.

[0063] Obviously, the above embodiments are only examples for detailed description of the utility model, and are not limited to the embodiments, and the utility model can be implemented in many other ways different from the description. Although the embodiments of the utility model are described in combination with the drawings, other different forms of modification and change can be made on the basis of the above description for the person skilled in the art, and such modification and change still belong to the protection scope defined by the appended claims of the utility model.
