[0002] The graphitization furnace is a device that converts conductive electrodes into graphite electrodes through high temperature. The power supply of the graphitization furnace usually sets the electrode clamping mechanism and the aluminum busbar clamping mechanism on the trolley. When it is necessary to supply power to the graphitization furnace, the power supply car moves to the designated furnace position, and the push device controls the electrode clamping mechanism to clamp the conductive electrode and the busbar clamping mechanism to clamp the power supply busbar, thereby realizing the power supply to the graphitization furnace.

[0003] In traditional technology, the transmission vehicle uses a double-clamp busbar clamp, that is, the push cylinders are distributed on both sides of the busbar clamp, and the busbar clamp is pushed by the push cylinder to clamp the transmission busbar. However, after the busbar clamping mechanism clamps the transmission busbar, it is pushed back by the transmission busbar, causing the cylinder bracket where the push cylinder is installed to be easily deformed, resulting in a limited service life of the busbar clamping mechanism, affecting the stability of the transmission vehicle.

[0035] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings; in the following description, many specific details are elaborated to facilitate a full understanding of the present invention; based on the embodiments of the present invention, ordinary technicians in this field can make similar improvements without violating the connotation of the present invention, but all other embodiments obtained without creative work cannot be used, so the present invention is not limited to the specific implementation disclosed below.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection, it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements, or it can be a "transmission connection", that is, a power connection through various appropriate methods such as belt drive, gear drive or sprocket drive. 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 Figure 1 In one embodiment, the first aspect of the present application provides a power transmission vehicle 100, which is used to transmit electricity to a graphitization furnace to complete the graphitization process of the graphitization furnace.

[0038] When the graphitization furnace needs to be powered, the power transmission vehicle 100 moves along the track to the corresponding furnace position of the graphitization furnace, and then connects the power transmission busbar 200 and the conductive electrode 300 of the graphitization furnace to draw power from the power transmission busbar 200 and transmit power to the graphitization furnace.

[0039] In this embodiment, the power transmission busbar 200 is arranged directly above the power transmission vehicle 100, and the graphitization furnace is arranged on one side of the power transmission vehicle 100. In fact, the power transmission busbar 200 can also be arranged on the side of the power transmission vehicle 100 opposite to the graphitization furnace, or directly below the power transmission vehicle 100, which is not specifically limited by this embodiment.

[0040] See also Figure 2 In one embodiment, the power transmission vehicle 100 includes: a vehicle body 10, a gantry 20, a conductive mechanism 30 and a translation mechanism 50. The gantry 20 is movably arranged on the vehicle body 10 forward and backward; the translation mechanism 50 is fixedly arranged on the vehicle body 10, and the translation mechanism 50 is used to drive the gantry 20 to move forward and backward; the conductive mechanism 30 is suspended on the gantry 20, and moves forward and backward driven by the gantry 20.

[0041] On one hand, the car body 10 is used as a carrier of the power transmission vehicle 100 and is used to install the gantry 20 and the translation mechanism 50. On the other hand, the car body 10 has a moving function, driving the power transmission vehicle 100 to move along the guide rail.

[0042] The conductive mechanism 30 is suspended by the gantry 20, so that the conductive mechanism 30 is only in contact with the gantry 20, and is not in direct contact with the vehicle body 10 and the translation mechanism 50. After the gantry 20 is insulated, only the conductive mechanism 30 is energized in the entire power transmission vehicle 100, which can prevent the staff from accidentally touching other parts of the conductive mechanism 30 and getting an electric shock, greatly improving the safety of the power transmission vehicle 100. Exemplarily, the insulation treatment can be to arrange an insulating plate (not shown) at the contact point between the gantry 20 and the conductive mechanism 30.

[0043] Specifically, the translation mechanism 50 may be a driving cylinder arranged along the front-rear direction of the power transmission vehicle 100, which will not be described in detail.

[0044] See also Figure 3 In one embodiment, the conductive mechanism 30 includes: a conductive base 31, a busbar clamping mechanism 32, a column 33 and an electrode clamping mechanism 34, wherein the busbar clamping mechanism 32 is arranged on the upper surface of the conductive base 31; the column 33 is suspended on the lower surface of the electrode clamping mechanism 34, and the electrode clamping mechanism 34 is fixed on the column 33.

[0045] In traditional technology, the electrode clamping mechanism and the busbar clamping mechanism usually use water-cooled copper bars to achieve electrical connection between the two. However, in actual work, the water-cooled copper bars are prone to bending or even breaking, and the conductive stability of the electrode clamping mechanism and the busbar clamping mechanism is poor.

[0046] The conductive mechanism 30 of this embodiment is achieved by installing the busbar clamping mechanism 32 on the conductive base 31, and the electrode clamping mechanism 34 is indirectly installed on the conductive base 31 through the column 33. The conductive base 31 acts as a rigid conductor, which greatly improves the stability of conduction between the electrode clamping mechanism 34 and the busbar clamping mechanism 32.

[0047] In addition, the electrode clamping mechanism 34 and the busbar clamping mechanism 32 are arranged on both sides of the conductive base 31 to reasonably utilize the space.

[0048] See also Figures 2 to 3 In one embodiment, the power transmission vehicle 100 further includes a lifting mechanism 40, which is fixedly disposed on the upper surface of the conductive base 31 and connected to the busbar clamping mechanism 32, and is used to drive the busbar clamping mechanism 32 to rise and fall.

[0049] The working principle of the conductive mechanism 30 is as follows: when power needs to be supplied, the translation mechanism 50 drives the gantry 20 to move, and the gantry 20 drives the conductive base 31 disposed on the gantry 20 to move, thereby driving the column 33 and the electrode clamping mechanism 34 of the conductive mechanism 30 to move, so that the electrode clamping mechanism 34 is docked with the conductive electrode 300 of the graphitization furnace;

[0050] The lifting mechanism 40 drives the busbar clamping mechanism 32 to move upward until the busbar clamping mechanism 32 docks with the power transmission busbar 200. When the power transmission vehicle 100 finishes power transmission, the translation mechanism 50 drives the conductive mechanism 30 away from the graphitization furnace to separate the electrode clamping mechanism 34 from the conductive electrode 300 of the graphitization furnace.

[0051] The busbar clamping mechanism 32 is separated from the power transmission busbar 200 by descending, which is mostly suitable for scenes with small height restrictions. However, for some scenes with large height restrictions, the busbar clamping mechanism 32 needs to be separated from the power transmission busbar 200 by side shifting.

[0052] The present application provides another specific implementation. Based on the present embodiment, the power transmission vehicle 100 replaces the lifting mechanism 40 with a side push mechanism (not shown), and the side push mechanism is connected to the busbar clamping mechanism 32 to drive the busbar clamping mechanism 32 to move linearly in the front-rear direction.

[0053] When the power transmission vehicle 100 needs to transmit power to the power transmission busbar 200, the side push mechanism drives the busbar clamping mechanism 32 to move forward in a straight line until the busbar clamping mechanism 32 reaches the branch busbar of the power transmission busbar 200, and the busbar clamping mechanism 32 clamps the power transmission busbar 200. When the power transmission is finished, the busbar clamping structure releases the power transmission busbar 200, and the side push mechanism drives the busbar clamping mechanism 32 to move backward, so that the busbar clamping mechanism 32 is separated from the branch busbar of the power transmission busbar 200, and the power transmission vehicle 100 can continue to move along the track to the furnace position of the next graphitization furnace.

[0054] It should be noted that: when the side-thrust structure is adopted, the relative positions of the power transmission vehicle 100 and the power transmission busbar 200 need to be adaptively adjusted.

[0055] The power transmission vehicle 100 of this embodiment drives the busbar clamping mechanism 32 to move forward and backward by adopting a side-pushing mechanism, that is, the busbar clamping mechanism 32 adopts a "side-in and side-out" working mode, which can be applied to scenes with large height restrictions.

[0056] See also Figure 3 and Figure 4 In one embodiment, the conductive mechanism 30 includes a plurality of busbar clamping mechanisms 32 arranged along the length direction of the conductive base 31. By using a plurality of busbar clamping mechanisms 32 to connect the power transmission busbar 200, the power transmission stability of the busbar clamping mechanisms 32 can be improved.

[0057] Furthermore, the busbar clamping mechanism 32 includes: two clamping plates 323, two clamping cylinders 322, a cylinder bracket 321 and a supporting frame (not shown).

[0058] The two clamping plates 323 are arranged opposite to each other and are used to cooperate with each other to clamp the power transmission busbar 200; the two clamping cylinders 322 are respectively arranged on the outsides of the two clamping plates 323, and the two clamping cylinders 322 are used to drive the two clamping plates 323 to move closer to or away from each other to clamp or release the power transmission busbar 200.

[0059] See also Figure 4 In one embodiment, the clamping cylinder 322 is fixedly connected to the support frame; the cylinder bracket 321 is fixedly arranged on the conductive base 31, and a strip hole (not shown) extending in the up-down direction is opened on the conductive base 31, and the clamping cylinder 322 is inserted into the strip hole. The clamping cylinder 322 can move within the limited range of the strip hole when the support frame is driven by the lifting mechanism 40. In other words, the clamping cylinder 322 can move up and down relative to the cylinder bracket 321, so as to adapt to the lifting mechanism 40 to drive the busbar clamping mechanism 32 to rise and fall.

[0060] In an alternative embodiment, two clamping plates 323 are arranged opposite to each other; two clamping cylinders 322 are respectively arranged on the outsides of the two clamping plates 323, and the two clamping cylinders 322 are used to drive the two clamping plates 323 to move closer to or away from each other to clamp or release the power transmission busbar 200.

[0061] Among them, the cylinder bracket 321 is fixedly set on the conductive base 31, the clamping cylinder 322 is fixedly set on the cylinder bracket 321, and the cylinder body of the clamping cylinder 322 is abutted against the supporting frame to buffer the reverse thrust of the power transmission busbar 200 on the clamping cylinder 322.

[0062] That is to say, the support frame and the clamping cylinder 322 are not fixed, and when the lifting mechanism 40 drives the busbar clamping mechanism 32 to rise and fall, it only drives the support frame in the busbar clamping mechanism 32 to move.

[0063] In the conventional technology, the applicant has found that the cylinder bracket 321 of the clamp-type busbar clamp often deforms. Due to the deformation of the cylinder bracket 321, the position of the clamping cylinder 322 installed on the cylinder bracket 321 is offset, so that the two clamping plates 323 cannot cooperate with each other to clamp the power transmission busbar 200, affecting the working stability of the power transmission vehicle 100.

[0064] The busbar clamping mechanism 32 provided in the present application is configured by setting a support frame and making the cylinder body of the clamping cylinder 322 abut against the support frame, so that the support frame supports the clamping cylinder 322 to balance the reverse thrust of the power transmission busbar 200 on the cylinder, thereby reducing the local stress of the cylinder bracket 321, so that the cylinder bracket 321 is not easily deformed, and the service life of the busbar clamping mechanism 32 is long.

[0065] See also Figure 5In one embodiment, the busbar clamping mechanism 32 further includes a conductive sheet 324 and an insulating sheet 325 , the conductive sheet 324 is disposed between the busbar clamping plate and the insulating sheet 325 , and the conductive sheet 324 is connected to the conductive base 31 .

[0066] Optionally, the conductive sheet 324 is fixed on the inner side of the clamping plate 323 .

[0067] Among them, the conductive sheet 324 is at least partially configured to be flexible to adapt to the movement of the clamping plate 323 driven by the clamping cylinder 322; the insulating sheet 325 is used to isolate the clamping plate 323 and the conductive sheet 324 to cut off the power transmission path between the conductive sheet 324 and the clamping plate 323.

[0068] By setting a conductive sheet 324 on the busbar clamping mechanism 32, and connecting the conductive sheet 324 to the clamping plate 323 and the conductive base 31 respectively, and setting an insulating sheet 325 between the clamping plate 323 and the conductive sheet 324, the electricity taken will be directly transmitted from the conductive base 31 to the conductive base 31, the power transmission path is unique and relatively short, and the power loss is small.

[0069] In one embodiment, the output shaft of the clamping cylinder 322 is pivotally connected to the clamping plate 323, and the clamping plate 323 can be flipped up and down relative to the clamping cylinder 322 to automatically adapt to the deformation of the power transmission busbar 200, thereby ensuring that the busbar clamping plate is tightly attached to the power transmission busbar 200.

[0070] Specifically, a fisheye ball head is provided on the output shaft of the clamping oil cylinder 322, a rotating shaft adapted to the fisheye ball head is provided on the back of the docking clamping plate, and a fisheye bearing is sleeved on the rotating shaft on the back of the docking clamping plate to realize the pivot connection of the clamping clamping plate 323 to the clamping oil cylinder 322. The structure of the fisheye bearing and the rotating shaft is relatively simple, and the matching is relatively stable.

[0071] See also Figure 3 and Figure 6 In one embodiment, the conductive mechanism 30 includes: a plurality of columns 33 spaced apart from each other, each column 33 being provided with a plurality of electrode clamping mechanisms 34 .

[0072] See also Figures 3 to 5 In a second aspect of the present application, a busbar clamping mechanism 32 is provided, which is used in the power transmission vehicle 100 of any of the above embodiments. The busbar clamping mechanism 32 includes:

[0073] Two pairs of clamping plates 323 are arranged opposite to each other to clamp the power transmission busbar 200;

[0074] Two pairs of clamping cylinders 322 are respectively connected to the clamping plates 323, and are used to drive the two pairs of clamping plates 323 to clamp or release the power transmission busbar 200;

[0075] The oil cylinder support 321, the clamping oil cylinder 322 is fixedly arranged on the oil cylinder support 321;

[0076] The support frame, the clamping cylinder 322 is in contact with the support frame, and the output shaft of the clamping cylinder 322 is connected to the clamping plate 323.

[0077] The busbar clamping mechanism 32 provided in the present application is configured by setting a support frame and making the clamping cylinder 322 abut against the support frame, so that the support frame supports the clamping cylinder 322 to balance the reverse thrust of the power transmission busbar 200 on the cylinder, thereby reducing the local stress of the cylinder bracket 321, so that the cylinder bracket 321 is not easily deformed, and the service life of the busbar clamping mechanism 32 is long.

[0078] In one embodiment, the output shaft of the clamping cylinder 322 is pivotally connected to the clamping plate 323 , and the clamping plate 323 can be turned upside down relative to the output shaft of the clamping cylinder 322 .

[0079] Specifically, a fisheye ball head is provided on the output shaft of the clamping oil cylinder 322, a rotating shaft adapted to the fisheye ball head is provided on the back side of the clamping clamping plate 323, and a fisheye bearing is sleeved on the rotating shaft on the back of the clamping clamping plate to realize the pivot connection of the clamping clamping plate 323 to the clamping oil cylinder 322. The structure of the fisheye bearing and the rotating shaft is relatively simple, and the matching is relatively stable.

[0080] The clamping plate 323 is configured to be flipped up and down relative to the output shaft of the clamping cylinder 322 to adapt to the deformation of the power transmission busbar 200 and improve the stability of the connection between the busbar clamping mechanism 32 and the power transmission busbar 200.

[0081] In one embodiment, a buffer pad (not shown) is provided on the inner side of the support frame, and the buffer pad is used to contact the clamping cylinder 322 .

[0082] The buffer pad can prevent the clamping cylinder 322 from directly and rigidly contacting the support frame, so as to reduce the local stress on the support frame and improve the service life of the support frame.

[0083] 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.
