Description

Technical Field

[0001] This utility model relates to the field of graphitized power transmission equipment technology, and more specifically, to a power transmission vehicle. Background Technology

[0002] A graphitization furnace is a device that converts conductive electrodes into graphite electrodes through high temperatures. Power supply to the graphitization furnace typically involves mounting the electrode clamping mechanism and the aluminum busbar clamping mechanism on a trolley. When power needs to be supplied to the graphitization furnace, the power supply trolley moves to the designated furnace position, and the jacking device controls the motor clamping mechanism to clamp the conductive electrodes, and the busbar clamping mechanism to clamp the power supply aluminum busbar, thereby supplying power to the graphitization furnace.

[0003] However, existing electrode clamping mechanisms are fixed by columns, while busbar clamping mechanisms are fixed by beams or frames. The electrode clamping mechanism and busbar clamping mechanism are connected by water-cooled cables, resulting in long power transmission paths, high power loss, complex structures, and high manufacturing costs.

[0004] Therefore, it is urgent to propose a new technical solution to address the problem. Utility Model Content

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings; many specific details are set forth in the following description in order to provide a full understanding of this utility model; based on the embodiments of this utility model, those skilled in the art can make similar improvements without departing from the spirit of this utility model, but cannot make all other embodiments obtained without creative effort, therefore this utility model is not limited to the specific embodiments disclosed below.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Please see Figures 1 to 6 To address the problems of long power transmission paths, high power loss, complex structures, and high manufacturing costs, in one embodiment, this utility model proposes a power supply vehicle 100, which is used to supply power to a graphitization furnace to complete the graphitization process of the furnace.

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

[0039] In this embodiment, the power supply busbar 200 is arranged directly above the power supply vehicle 100, and the graphitization furnace is arranged on one side of the power supply vehicle 100.

[0040] In practice, the power supply busbar 200 can also be arranged on the side of the power supply vehicle 100 opposite to the graphitization furnace, or directly below the power supply vehicle 100, without being limited by the specific implementation of this embodiment.

[0041] Please see Figures 1 to 6 In one embodiment, the power transmission vehicle 100 includes a busbar clamping mechanism 30 and a conductive base 20. The busbar clamping mechanism 30 includes a conductive sheet 31 and a clamping plate 33. An insulating sheet 36 is provided between the conductive sheet 31 and the clamping plate 33. The insulating sheet 36 is used to isolate the clamping plate 33 and the conductive sheet 31. The conductive sheet 31 is connected to the conductive base 20 and the clamping plate 33 respectively. By setting the clamping plate 33, the conductive sheet 31 and the insulating sheet 36 on the busbar clamping mechanism 30, and the conductive sheet 36 is connected to the clamping plate 33 and the conductive base 20 respectively, and the insulating sheet 36 is placed between the clamping plate 33 and the conductive sheet 31, the electricity is directly transmitted from the conductive sheet 31 to the conductive base 20. The power transmission path is unique and relatively short, and the power loss is small.

[0042] Please see Figure 2In one embodiment, the power transmission vehicle 100 includes: a vehicle body 10, a gantry 11, a column 37, a busbar clamping mechanism 30, an electrode clamping mechanism 38, and a translation mechanism 50. The gantry 11 is movably mounted on the vehicle body 10. The translation mechanism 50 is fixedly mounted on the vehicle body 10 and is used to drive the gantry 11 to move back and forth. The busbar clamping mechanism 30 and the electrode clamping mechanism 38 are suspended on the gantry 11 and move back and forth under the drive of the gantry 11. The electrode clamping mechanism 38 is mounted on the column 37, the column 37 is mounted on the lower surface of the conductive base 20, and the busbar clamping mechanism 30 is mounted on the lower surface of the electrode clamping mechanism 38.

[0043] On the one hand, the car body 10 serves as the carrier of the power transmission vehicle 100, and is used to install the gantry 11 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.

[0044] The busbar clamping mechanism 30 and the electrode clamping mechanism 38 are suspended via the gantry 20. This ensures that the busbar clamping mechanism 30 and the electrode clamping mechanism 38 only contact the gantry 20 and do not directly contact the vehicle body 10 or the translation mechanism 50. After insulating the gantry 11, only the busbar clamping mechanism 30 and the electrode clamping mechanism 38 are energized in the entire trolley 100, preventing accidental electric shock to personnel who touch any other parts besides these components, thus significantly improving the safety of the trolley 100. For example, the insulation treatment can be achieved by placing an insulating plate (not shown) at the contact point between the gantry 11 and the busbar clamping mechanism 30 and the electrode clamping mechanism 38.

[0045] Specifically, the translation mechanism 50 can be a drive cylinder arranged along the front and rear direction of the trolley 100, which will not be described in detail here.

[0046] Please see Figure 3 and Figure 4 In one embodiment, the busbar clamping mechanism 30 includes: two clamping plates 33, two clamping cylinders 32, a cylinder bracket 35, and a support frame 34.

[0047] Two clamping plates 33 are arranged opposite each other to clamp the power supply busbar 200; two clamping cylinders 32 are respectively located on the outside of the two clamping plates 33, and the two clamping cylinders 32 are used to drive the two clamping plates 33 to move closer or further away from each other to clamp or release the power supply busbar 200.

[0048] In one embodiment, the clamping cylinder 32 is fixedly connected to the support frame 34; the cylinder bracket 35 is fixedly mounted on the conductive base 20, and the conductive base 20 has a vertically extending strip hole (not shown), through which the clamping cylinder 32 passes. The clamping cylinder 32 can move within the restricted range of the strip hole when the support frame 34 is driven by the lifting mechanism 40.

[0049] In other words, the clamping cylinder 32 can move up and down relative to the cylinder bracket 35 to adapt to the lifting mechanism 40 driving the busbar clamping mechanism 30 to rise and fall.

[0050] In another alternative embodiment, two clamping plates 33 are arranged opposite to each other; two clamping cylinders 32 are respectively arranged on the outside of the two clamping plates 33, and the two clamping cylinders 32 are used to drive the two clamping plates 33 to move closer or further away from each other, so as to clamp or release the power supply busbar 200.

[0051] The hydraulic cylinder bracket 35 is fixedly mounted on the conductive base 20, and the clamping hydraulic cylinder 32 is fixedly mounted on the hydraulic cylinder bracket 35. The cylinder body of the clamping hydraulic cylinder 32 abuts against the support frame 34 to buffer the reverse thrust of the power supply busbar 200 on the clamping hydraulic cylinder 32.

[0052] In other words, the support frame 34 and the clamping cylinder 32 are not fixed. When the lifting mechanism 40 drives the busbar clamping mechanism 30 to rise and fall, it only drives the support frame 34 in the busbar clamping mechanism 30 to move.

[0053] Furthermore, the lifting mechanism can be configured in two sets 40, with the two sets of lifting mechanisms 40 respectively arranged on the left and right sides of the support frame 34 to improve the stability of the lifting of the support frame 34.

[0054] In conventional technology, the applicant found that the hydraulic cylinder bracket 35 of the clamp-type busbar clamp often deforms. Due to the deformation of the hydraulic cylinder bracket 35, the position of the clamping hydraulic cylinder 32 installed on the hydraulic cylinder bracket 35 shifts, so that the two clamping plates 33 cannot cooperate to clamp the power supply busbar 200, affecting the stability of the power supply vehicle 100.

[0055] The busbar clamping mechanism 30 of this application, by setting a support frame 34 and having the cylinder body of the clamping cylinder 32 abut against the support frame 34, supports the clamping cylinder 32 to balance the reverse thrust of the power supply busbar 200 on the cylinder, thereby reducing the local stress of the cylinder support 35, making the cylinder support 35 less prone to deformation, and extending the service life of the busbar clamping mechanism 30.

[0056] Please see Figure 5 In one embodiment, the busbar clamping mechanism 30 further includes a conductive sheet 31 and an insulating sheet 36. The conductive sheet 31 is disposed between the clamping plate 33 and the insulating sheet 36, and the conductive sheet 31 is connected to the conductive base 20.

[0057] Optionally, the conductive sheet 31 is fixed to the inner side of the clamping plate 33.

[0058] The conductive sheet 31 is at least partially configured to be flexible to accommodate the movement of the clamping plate 33 driven by the clamping cylinder 32; the insulating sheet 36 is used to isolate the clamping plate 33 from the conductive sheet 31 to cut off the power transmission path between the conductive sheet 31 and the clamping plate 33.

[0059] By setting a conductive sheet 31 on the busbar clamping mechanism 30 and connecting the conductive sheet 31 to the clamping plate 33 and the conductive base 20, and setting an insulating sheet 36 between the clamping plate 33 and the conductive sheet 31, the electricity taken will be directly transmitted from the conductive base 20 to the conductive base 20. The power transmission path is unique and relatively short, and the power loss is small.

[0060] Furthermore, the conductive sheet 31 includes a first mounting portion 311, a flexible portion 312, and a second mounting portion 313. The flexible portion 312 is connected to the first mounting portion 311 and the second mounting portion 313 respectively. The first mounting portion 311 is disposed between the conductive base 20 and the cylinder bracket 35, and the first mounting portion 311 and the cylinder bracket 35 are fixed on the conductive base 20 by fasteners.

[0061] The second mounting part 313 is fitted onto the inner side of the clamping plate 33, that is, the side of the clamping plate 33 facing the power supply busbar 200. The flexible part 312 can be rotated, bent, or deformed under external force to adapt to changes in the position of the clamping plate 33.

[0062] In one embodiment, the output shaft of the clamping cylinder 32 is pivotally connected to the clamping plate 33. The clamping plate 33 can rotate up and down relative to the clamping cylinder 32 to automatically adapt to the deformation of the power supply busbar 200, thereby ensuring that the clamping plate 33 is in close contact with the power supply busbar 200.

[0063] Specifically, the output shaft of the clamping cylinder 32 is equipped with a fisheye head, and the back side of the clamping plate 33 is equipped with a rotating shaft adapted to the fisheye head. The fisheye bearing is sleeved on the rotating shaft on the back of the clamping plate 33 so that the clamping plate 33 is pivotally connected to the clamping cylinder 32. The structure of the fisheye bearing and the rotating shaft is relatively simple, and the fit is relatively stable.

[0064] In one embodiment, a buffer pad (not shown) is provided on the inner side of the support frame 34 for contacting the cylinder body of the clamping cylinder 32.

[0065] The buffer pad can prevent the clamping cylinder 32 from directly and rigidly contacting the support frame 34, thereby reducing the local stress on the support frame 34 and improving the service life of the support frame 34.

[0066] In summary, compared with the prior art, this utility model provides a clamping plate 33, a conductive sheet 31, and an insulating sheet 36 on the busbar clamping mechanism 30. The conductive sheet 36 is connected to the clamping plate 33 and the conductive base 20 respectively, and the insulating sheet 36 is placed between the clamping plate 33 and the conductive sheet 31. In this way, the electricity is directly transmitted from the conductive sheet 31 to the conductive base 20. The power transmission path is unique and relatively short, and the power loss is small.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the scope of protection of this application.
