DETAILED DESCRIPTION

[0026] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0028] See also Figure 1 to Figure 4 In one embodiment of the present application, a rectifying trolley 100 is provided for transmitting electricity to a U-shaped furnace 200. The two end walls of the U-shaped furnace 200 are arranged toward the power transmission trolley, and a plurality of conductive electrodes are arranged on each end wall. The U-shaped furnace 200 can be formed by connecting the tail ends of two adjacent linear furnaces with a conductor, or it can be formed in one piece.

[0029] The rectifying vehicle 100 includes a vehicle body 10 , a power supply mechanism 20 , a first pushing mechanism 30 , and a second pushing mechanism 40 .

[0030] The power supply mechanism 20 is provided on the vehicle body 10 and is electrically connected to the first pushing mechanism 30 and the second pushing mechanism 40. The first pushing mechanism 30 is used to connect with the conductive electrode of one end wall of the U-shaped furnace 200, and the second pushing mechanism 40 is used to connect with the conductive electrode of the other end wall of the U-shaped furnace 200.

[0031] Specifically, when the U-shaped furnace 200 needs to supply power, the operator controls the rectifying trolley 100 to move to the designated furnace position, and controls the first pushing mechanism 30 and the second pushing mechanism 40 to move toward the graphitization furnace until the first pushing mechanism 30 is connected to the conductive electrode of one end wall of the U-shaped furnace 200, and the second pushing mechanism 40 is connected to the conductive electrode of the other end wall of the U-shaped furnace 200. When the power supply is finished, the first pushing mechanism 30 and the second pushing mechanism 40 are controlled to separate from the conductive electrode respectively, and the rectifying trolley 100 is controlled to leave the U-shaped furnace 200.

[0032] The rectifier trolley 100 of this embodiment realizes the rectifier trolley 100 supplying power to the U-shaped furnace 200 or stopping supplying power to the U-shaped furnace 200 by setting a first jacking mechanism 30 and a second jacking mechanism 40, and controlling the docking or separation of the first jacking mechanism 30, the second jacking mechanism 40 and the U-shaped furnace 200.

[0033] In conventional technology, the power supply device is usually fixed, and a large number of busbars need to be connected between the power supply device and the U-shaped furnace 200 to achieve electrical connection between the two. In addition, the copper busbars need to be manually removed or installed using tools to switch the power supply device and the U-shaped furnace 200 between a connected state and a disconnected state.

[0034] The power supply mechanism 20 on the rectifying trolley 100 of the present application moves with the trolley body 10, and then docks with any U-shaped furnace 200 through the first pushing mechanism 30 and the second pushing mechanism 40, which can greatly reduce the amount of copper bars used. In addition, the first pushing mechanism 30 and the second pushing mechanism 40 can be controlled to complete the docking of the conductive electrode with the U-shaped furnace 200, without the need to disassemble and assemble the copper bars, thereby reducing labor costs.

[0035] Specifically, the power supply mechanism 20 includes: a power supply device 21, a rectifier transformer 22, a rectifier cabinet 24 and a short-circuit network 23. The rectifier transformer 22 is electrically connected to the power supply device 21 and to the short-circuit network 24, and the rectifier cabinet 24 is connected to the short-circuit network 23.

[0036] After the power taking device 21 takes power from the outside, it transmits it to the rectifier transformer 22. After being rectified and output by the rectifier transformer 22, it enters the rectifier cabinet 24 through the short-circuit network 23, and then outputs to the first pushing mechanism 30 and the second pushing mechanism 40 through the short-circuit network 23.

[0037] In a specific embodiment, a water-cooling cable 50 is connected between the short circuit network 24 and the first pushing mechanism 30 , and a water-cooling cable 50 is provided between the short circuit network 24 and the second pushing mechanism 40 .

[0038] The water-cooled cable 50 is a linear conductor with a water channel in the middle and an electric cable wrapped around it. The water-cooled cable 50 can reduce the effect of heat generation on the first and second pushing mechanisms 30 and 40 while achieving electrical connection between the short network and the first pushing mechanism 30 and between the electric short network 23 and the second pushing mechanism 40.

[0039] Specifically, the first pushing mechanism 30 includes: a first frame 31 , a first driving member 32 and a first pressing plate 33 . The first driving member 32 is fixedly disposed on the frame, and the first pressing plate 33 is disposed at one end of the output shaft of the first driving member 32 .

[0040] The first driving member 32 may be a double extension cylinder, one output shaft of which is used to connect with the first pressing plate 33, and the other output shaft is used to abut against the reaction wall. The reaction force of the U-shaped furnace 200 on the rectifying trolley 100 is balanced by the thrust of the double extension cylinder against the reaction wall.

[0041] Furthermore, the upper end of the first pressing plate 33 is bent inward to form a bent portion 34 , and the bent portion 34 is provided with a plurality of water-cooled copper heads 35 .

[0042] In order to ensure that the first pressing plate 33 is in normal working condition, a water tank is provided behind the first pressing plate 33. The water-cooling copper head 35 is the input and output end of the water tank. The water-cooling copper head is used to plug the water-cooling cable 50. The bending portion 34 can reduce the bending radius of the water-cooling cable 50, thereby reducing the risk of water channel blockage or even breakage of the water-cooling cable 50 due to excessive bending.

[0043] Furthermore, a running wheel 36 is provided at the lower end of the first pressing plate 33 . The running wheel 36 is in contact with the vehicle body 10 and can drive the first pressing plate 33 to move closer to or away from the conductive electrode of the U-shaped furnace 200 .

[0044] The travel wheel 36 can provide support force to the first pressure plate 33 , thereby enhancing the ability of the first driving member 32 to overcome radial loads.

[0045] Specifically, the second pushing mechanism 40 includes: a second frame 41 , a second driving member 42 and a second pressing plate 43 . The second driving member 42 is fixedly disposed on the frame, and the second pressing plate 43 is disposed at one end of the output shaft of the second driving member 42 .

[0046] The second driving member 42 may be a double extension cylinder, one output shaft of which is used to connect with the second pressing plate 43, and the other output shaft is used to abut against the reaction wall. The reaction force of the U-shaped furnace 200 on the rectifying trolley 100 is balanced by the thrust of the double extension cylinder against the reaction wall.

[0047] Furthermore, the upper end of the second pressing plate 43 is bent inward to form a bent portion 44 , and the bent portion 44 is provided with a plurality of water-cooled copper heads 45 .

[0048] In order to ensure that the second pressing plate 43 is in normal working condition, a water tank is provided behind the second pressing plate 43. The water-cooling copper head 45 is the input and output end of the water tank. The water-cooling copper head 45 is used to plug the water-cooling cable 50, and the bending portion 44 can reduce the bending radius of the water-cooling cable 50, thereby reducing the risk of water channel blockage or even breakage of the water-cooling cable 50 due to excessive bending.

[0049] Furthermore, a travel wheel 46 is provided at the lower end of the second pressing plate 43 . The travel wheel 46 is in contact with the vehicle body 10 and can drive the second pressing plate 43 to move closer to or away from the conductive electrode of the U-shaped furnace 200 .

[0050] The travel wheel 46 can provide support force to the second pressure plate 43 , thereby enhancing the ability of the second driving member 42 to overcome radial loads.

[0051] In a specific embodiment, the vehicle body 10 is further provided with an oil-air cooler 60 , and the oil-air cooler 60 is connected to the rectifier transformer 22 .

[0052] The oil-air cooler 60 is used to cool the rectifier transformer 22 to ensure that the rectifier transformer 22 maintains a normal operating temperature during operation, so that the operation of the rectifier transformer 22 is stable and reliable.

[0053] In a specific embodiment, the vehicle body 10 is also provided with a PLC control cabinet.

[0054] The PLC control cabinet carries electronic components and can automatically control the rectifier trolley 100 to improve the automation level of the rectifier trolley 100.

[0055] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom still fall within the scope of protection created by this application.
