Exemplarily, the graphitization device is an inner string graphitization furnace 100, which includes a rectangular furnace body 110 and conductive electrodes 120 arranged on both end surfaces of the furnace body.

[0034] The cooling device of the pressure plate of the power transmission vehicle includes a mobile body 200, a cooling mechanism 300 and a pushing mechanism 400. The cooling mechanism 300 and the pushing mechanism 400 are both arranged on the mobile body 200. The pushing mechanism 400 is provided with a pressure plate 410. The pressure plate 410 is used to connect with the conductive electrode of the graphitization furnace. The pressure plate 410 includes a pushing plate 411 and a cooling plate 412. The cooling plate 412 is arranged in close contact with the pushing plate 411. The cooling mechanism 300 transports the coolant to the cooling plate 412 through a pipeline, which effectively reduces the temperature of the pressure plate 410 during operation and increases the service life of the pressure plate 410. In this embodiment, the mobile body 200 is the body structure of the rectifier trolley.

[0035] In one embodiment, the cooling mechanism 300 includes a first frame 310 and a second frame 320, the second frame 320 is arranged above the first frame 310, the first frame 210 is placed on the mobile body 200, a first cooling box 330 is arranged on the first frame 310, and a second cooling box 340 is arranged on the second frame 320, and the cooling plate 412 is connected to the first cooling box 330 and / or the second cooling box 340 through a pipeline; by setting the first cooling box 330 and the second cooling box 340, the coolant in the first cooling box 330 or the second cooling box 340 is sent to the cooling plate 412 through the pipeline, and then flows back to the first cooling box 330 or the second cooling box 340 through the pipeline, so as to effectively reduce the temperature of the pressing plate 410 when it is working, and improve the efficiency of the pressing plate 410. In addition, by setting the first cooling box 330 and the second cooling box 340, when the cooling plate 412 is connected to the first cooling box 330 through a pipeline, the second cooling box 340 can temporarily stop working; after the first cooling box 330 has been working for a long time, the cooling plate 412 can be switched to be connected to the second cooling box 340 through a pipeline, and the first cooling box 330 can temporarily stop working, which can effectively improve the service life of the first cooling box 330 and the second cooling box 340; in this embodiment, the first cooling box 330 and the second cooling box 340 can both adopt cooling circulating water machine equipment, and the pipeline connected to the water inlet and outlet of the cooling plate 412 is designed as a hose structure, so the liquid outlet port and the reflux port of the first cooling box 330 and the second cooling box 340 can be switched back and forth.

[0036] In one embodiment, one side of the first cooling box 330 is connected to one side of the second cooling box 340 through a connecting pipe 350, and a switch valve (not shown) is provided on the connecting pipe 350. The connection state of the first cooling box 330 and the second cooling box 340 is adjusted by the switch valve, so that the first cooling box 330 is connected to the second cooling box 340. When the pressure plate 410 is connected to the first cooling box 330 or the second cooling box 340 through a pipeline, the coolant in the first cooling box 330 and the second cooling box 340 can be shared by opening the switch valve, thereby effectively improving the cooling efficiency of the coolant that flows back to the first cooling box 330 or the second cooling box 340 through the pressure plate 410.

[0039] Furthermore, a guardrail 370 is disposed on one side of the ladder 360 of the second frame 320. The guardrail 370 is a semicircular structure and separates the second frame 320 from the external environment, so that the second frame 320 has a better recognition.

[0040] In one embodiment, a power supply device 500 is also provided on the mobile body 200, and the power supply device 500 is used to supply power to the internal series graphitization furnace; the power supply device 500 itself does not involve the inventive point of the utility model, and the solutions in the prior art can be adopted; specifically, the power supply device 500 includes an electric control cabinet 510, a rectifier cabinet A520, a high-power rectifier transformer 530, a rectifier cabinet B540, and a positive output terminal 501 and a negative output terminal 502 of the power supply device 500, and the positive output terminal 501 and the negative output terminal 502 of the power supply device 500 are connected to the push plate 411 through a connecting cable 503, and the power supply device 500 uses the connecting cable 503 to realize the power supply operation of the push mechanism 400.

[0042] Specifically, one end of the push cylinder 430 is connected to the cooling plate 412, the cooling plate 412 is hollow, the water inlet and the water outlet are arranged on one side of the cooling plate 412, and a cooling channel is arranged in the cooling plate 412. The cooling channel is designed into a serpentine structure such as S-type, U-type, etc. according to needs, which can effectively improve the cooling efficiency of the coolant in the cooling plate 412; the cooling channel can also be designed into other curved structures such as W-type, etc. according to needs.

[0043] Furthermore, a docking ring column 4121 is provided in the cooling plate 412, and through holes 4122 are provided at intervals on the docking ring column 4121. The cooling plate 412 is connected to the push plate 411 through a locking piece 413. The locking piece 413 passes through the through hole 4122 and is fixed in the push plate 411, thereby realizing a fixed connection between the cooling plate 412 and the push plate 411.

[0045] Furthermore, an insulating plate 415 is provided between the first docking plate 414 and the second docking plate 431, and the insulating plate 415 separates the first docking plate 414 from the second docking plate 431, thereby preventing the electricity on the pushing plate 411 from being transmitted to the pushing cylinder 430 through the cooling plate 412, thereby improving the service life of the pushing cylinder 430.
