[0002] The power transmission car is a rectifier unit used to transmit power to the graphitization furnace. The power transmission car is provided with an electrode clamping mechanism and a busbar clamping mechanism electrically connected to each other. During the power transmission process, the electrode clamping mechanism clamps the conductive electrode of the graphitization furnace, and the busbar clamping mechanism clamps the power transmission busbar to support the production of the graphitization furnace.

[0003] In the prior art, the live part includes an electrode clamping mechanism and a column, and the electrode clamping mechanism is fixedly arranged on a support portion extending from one side of the column, see CN202310255343.1. In the scenario where the power transmission vehicle transmits electricity to the graphitization furnace, the distance between the two adjacent conductive electrodes above and below the graphitization furnace is relatively fixed. When the staff finds that the height of the electrode clamp is not suitable for the conductive electrode of the graphitization furnace, a small steel plate of 1 to 2 mm is usually added between the support portion and the electrode clamp as a gasket to fine-tune the height of the electrode clamping mechanism. However, each power transmission vehicle has several electrode clamps, and each electrode clamp needs to use a gasket to adjust the height, which makes the operation too cumbersome and inefficient.

Compared with the prior art, the electrode clamping mechanism 100 provided by the present invention is provided by sleeve-arranging the electrode clamp 30 on the positioning column 11, and the electrode clamp 30 pivots relative to the positioning column 11. In the scenario where the power transmission vehicle transmits electricity to the graphitization furnace, the distance between the two adjacent conductive electrodes of the graphitization furnace is relatively fixed. The lifting mechanism 43 drives the lifting of the conductive frame 10, thereby adjusting the height of the electrode clamp 30 fixed on the positioning column 11 of the conductive frame 10 as a whole, that is, the operator can complete the adjustment of the electrode clamp 30 at one time to adapt to the graphitization furnace, which is simple and reliable to operate and highly practical. There is no need to equip a small steel plate as a height adjustment accessory, and the structure is simple and the use cost is low.

[0036] See also Figures 3 to 5 In one embodiment, two shaft sleeves 311 distributed along the axial direction of the positioning column 11 are fixedly provided, and the two shaft sleeves 311 are respectively clamped to the clamping arm 31 from the upper and lower sides of the clamping arm 31.

[0037] Furthermore, two sleeves 311 spaced apart from each other are fixedly disposed on the positioning column 11, and the two sleeves 311 are respectively clamped to the clamping arm 31 from the upper and lower sides of the clamping arm 31, wherein the cross-sectional area of ​​the sleeve 311 is configured to be slightly larger than the cavity 312 to achieve an interference fit between the sleeve 311 and the positioning column 11.

[0040] A cavity 312 communicating with the shaft sleeve 311 is formed through the side of the clamping arm 31 . A coupling (not shown) is provided on the positioning column 11 and is located in the cavity 312 , thereby fixing the clamping arm 31 on the positioning column 11 .

[0041] Specifically, the coupling may be a circular disk with a central hole, which is fixedly disposed on the positioning column 11 .

When the electrode clamp 30 is in the clamping state, the driving oil cylinder 32 drives the clamping arms 31 to move closer to each other, driving the two electrode clamping plates 33 to move closer to each other, so as to stably clamp the conductive electrode; when the electrode clamp 30 is in the released state, the driving oil cylinder 32 drives the clamping arms 31 to move away from each other, so as to control the two electrode clamping plates 33 to be set away from each other.

[0044] The clamping arm 31 is provided with a cavity 312, and the positioning column 11 is inserted into the cavity 312 of the clamping arm 31. The cavity 312 can be set in the middle position or close to one side of the electrode clamping plate 33, so that the connection between the positioning column 11 and the clamping arm 31 can be used as a support point, which can ensure that the entire electrode clamp 30 switches between the clamping state and the release state stably and reliably.

[0048] Specifically, the fixing plate 341 is provided with a through hole (not shown) for fasteners (not shown) to pass through and fix to the column 20. The contact copper bar 343 is arranged on the insulating pad 332 of the electrode clamping plate 33, that is, the side that contacts the conductive electrode of the graphitization furnace.

[0052] Specifically, the power transmission vehicle 40 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 44 drives the gantry 42 to move forward, and the lifting mechanism 43 drives the electrode clamping mechanism 100 to descend until the electrode clamping mechanism 100 is respectively connected with the conductive electrode of the graphitization furnace and the power transmission busbar; when switched to the idle state, the translation mechanism 44 drives the gantry 42 to move backward, and the lifting mechanism 43 drives the electrode clamping mechanism 100 to rise until the electrode clamping mechanism 100 is respectively separated from the conductive electrode of the graphitization furnace and the power transmission busbar.
