[0002] This application relates to the field of power supply equipment for graphitization furnaces, and in particular to a locking frame and power supply busbar device. Background Technology

[0003] A graphitization furnace is a device that converts non-graphitic carbon materials into graphitic carbon materials at high temperatures. A power transmission vehicle, as a mobile power transmission device, can supply power to a designated graphitization furnace. When the power transmission vehicle is in power transmission mode, it is electrically connected to both the power transmission busbar and the conductive electrodes of the graphitization furnace.

[0004] In related technologies, see Chinese Patent Application No. CN202210901044.6: A power transmission vehicle connects to an aluminum busbar by laterally pushing a copper plate against it. However, in actual use, the power transmission busbar is fixed by a busbar mounting bracket, and the busbar connection assembly abuts against the busbar, allowing the power transmission vehicle to draw power from it. When the busbar is pushed on top of the power transmission vehicle, the busbar also pushes the vehicle backward, resulting in excessive internal stress and a short service life.

[0005] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0031] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other. Embodiments of this application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0033] In scenarios where a power supply vehicle (PSV) delivers power to a graphitization furnace, there are typically multiple graphitization furnaces, a PSV, and a power supply busbar. Each graphitization furnace has two end walls. The PSV is positioned at one end of one of these end walls, maintaining a certain distance from the furnace. The PSV can move along the direction in which the multiple graphitization furnaces are arranged. The power supply busbar is positioned around the multiple graphitization furnaces and at a certain height above the ground. Specifically, the PSV is located directly below the power supply busbar, and the distance between the busbar and the ground allows the PSV to pass through.

[0034] Please see Figures 1-3 and Figure 5 One embodiment of this application provides a pressure plate device 10 for a trolley 100. For a description of the orientation (e.g., up / down, left / right, front / back) of the pressure plate device 10, please refer to [link to relevant documentation]. Figure 1 The coordinate system in the diagram. The pressure plate device 10 includes:

[0035] A pressure plate assembly 11 that can be raised and lowered relative to the power supply busbar 400°;

[0036] The pressure plate assembly 11 is fixedly connected with several locking parts 1 that can extend and retract back and forth. When the pressure plate assembly 11 rises to contact the power supply busbar 400, the locking parts 1 cooperate with several locking parts 2 fixed at a preset height to limit the pressure plate assembly 11 to the preset height position.

[0037] The pressure plate device 10 of this application includes a locking member 1, which is connected to a locking member 2 fixed at a preset height, so that the pressure plate assembly 11 is locked at the preset height position. That is, the cooperation of the locking member 1 and the locking member 2 fixes the pressure plate assembly 11 to the power supply busbar 400, so as to convert the reaction force of the power supply busbar 400 on the pressure plate assembly into the internal force of the power supply busbar 400, reduce the force borne by the power supply vehicle 100, and improve the service life of the power supply vehicle.

[0038] Furthermore, when the pressure plate assembly 11 rises to a preset position and contacts the power supply busbar 400, locking element one and locking element two engage to lock the pressure plate assembly 11 at a fixed height and ensure it remains connected to the power supply busbar 400, thus guaranteeing a stable and reliable connection between the pressure plate and the power supply busbar 400. Even in the event of a hydraulic system malfunction, the pressure plate will not fall.

[0039] The pressure plate assembly 11 is driven by a driving component to move up and down. It is understood that the pressure plate assembly must be driven by a driving component to achieve its vertical movement (described in detail below). Specifically, when the power supply vehicle 100 needs to supply power, the driving component drives the pressure plate assembly 11 upward until it contacts the power supply busbar 400; when the power supply vehicle 100 completes power supply and prepares to supply power to the next graphitization furnace, the driving component drives the pressure plate assembly 11 downward until it separates from the power supply busbar 400. The power supply busbar 400 can be a power supply busbar, which is always directly above the pressure plate assembly 11.

[0040] In this embodiment, the clamping cylinder 112 is used as the driving component.

[0041] Several locking elements are fixed to the power supply busbar 400. Therefore, when locking element 1 and locking element 2 are engaged, locking element 1 is indirectly fixed to the power supply busbar 400 through locking element 2. Of course, the locking elements can also be fixed to the ceiling or side wall.

[0042] In one specific embodiment, locking component one includes a positioning pin 121, which moves back and forth under the drive of the hydraulic cylinder 12; locking component two includes a plug 230, which has a plug hole 231 that cooperates with the positioning pin 121.

[0043] In this embodiment, the piston rod of the hydraulic cylinder serves as the positioning pin 121. Initially, the piston rod of the drive cylinder 12 retracts into the cylinder body. When the pressure plate assembly 11 contacts the power supply busbar 400, the piston rod of the drive cylinder 12 extends out of the cylinder body and into the insertion hole 231 of the connector 230. After power supply is completed, the piston rod of the drive cylinder 12 retracts back into the cylinder body, allowing the pressure plate assembly 11 to descend under the influence of the clamping cylinder 112, facilitating the movement of the power supply vehicle 100. The combination of the positioning pin 121 and the connector 230 has a simple structure and good fixing effect.

[0044] It is understandable that locking component one can also be set as plug-in component 230, and locking component two can be set as drive cylinder 12.

[0045] In fact, when the pressure plate assembly 11 contacts the power supply busbar 400, locking element one and locking element two cooperate to fix the aluminum busbar assembly to the specified height. Therefore, locking element one and locking element two are not limited to the form of positioning pin 121 and plug-in element 230.

[0046] For example, the first locking element is a handle, and the second locking element is a clamp, which is fixed to the power supply busbar 400. When the pressure plate assembly 11 moves to contact the power supply busbar 400, the clamp can be controlled to clamp the handle to achieve fixation.

[0047] Furthermore, there are two connectors 230; the drive cylinder includes a double extension cylinder, and the two piston rods of the double extension cylinder are respectively connected to the two connectors 230.

[0048] It should be noted that a double-extension hydraulic cylinder is a cylinder with a cylinder body and two piston rods located on the same straight line. The two piston rods of the double-extension hydraulic cylinder extend or retract in the front-rear direction. Correspondingly, the connector 230 is also distributed in the front-rear direction, and the connector 230 is provided with a front-rear insertion hole 231.

[0049] When the pressure plate device 10 contacts the power supply busbar 400, the two piston rods of the control double extension cylinder extend into the insertion holes 231 of the two plug-in parts 230 respectively. The double extension cylinder is connected to the two plug-in parts 230 through the two piston rods, thereby improving the reliability of the position fixation of the pressure plate device 10.

[0050] In other embodiments, the drive cylinder 12 can be two unidirectional cylinders arranged in opposite directions, or only one unidirectional cylinder can be provided to cooperate with a connector 230. Compared with unidirectional cylinders, the double extension cylinders do not require synchronization, which can ensure that the stroke of the two piston rods is consistent, making it easy to use.

[0051] In one specific embodiment, the pressure plate assembly 11 includes: a base plate 111, a clamping cylinder 112, and a pressure plate unit 113; the cylinder body of the clamping cylinder 112 is connected to the base plate 111, and the piston rod of the clamping cylinder 112 is connected to the pressure plate unit 113; one pressure plate unit 113 corresponds to multiple clamping cylinders 112. The base plate 111 serves as the mounting carrier for the clamping cylinder 112 and the drive cylinder 12.

[0052] In this embodiment, three pressure plate units 113 are arranged along the left-right direction, and each pressure plate is equipped with four clamping cylinders 112. Specifically, the piston rods of the four clamping cylinders 112 respectively abut against the four corners of the lower surface of the pressure plate assembly 11. To make the thrust more uniform, a clamping block can also be provided at one end of the output shaft of the clamping cylinder 112, and the clamping block contacts the lower surface of the pressure plate assembly 11. The clamping cylinder 112, as one of the driving components, can drive the push plate unit to rise and fall, so as to realize the contact or separation of the push plate unit with the power supply busbar 400.

[0053] Of course, the number of pressure plate units 113 and the number and position of top hydraulic cylinders can be adjusted adaptively to meet actual usage requirements.

[0054] In one specific embodiment, there are several drive cylinders 12 and several pressure plate units 113, with the drive cylinders 12 located on the left and right sides of the pressure plate units 113.

[0055] In this embodiment, since the three pressure plate units 113 and the four drive cylinders 12 are distributed alternately in the left-right direction, each pressure plate unit 113 has a drive cylinder 12 on both its left and right sides. This arrangement of the drive cylinders 12 and the pressure plate units 113 allows each pressure plate unit 113 to have a drive cylinder 12 on both sides, and two adjacent pressure plate units 113 can share one drive cylinder 12.

[0056] It should be noted that the drive cylinder 12 is fixed to the base plate 111 by the cylinder mounting seat 122 and is arranged in the front-to-back direction, that is, the piston rod of the drive cylinder 12 extends or retracts in the front-to-back direction. In other embodiments, the drive cylinder 12 can also be arranged in the left-to-right direction, that is, the output shaft extends or retracts in the left-to-right direction. One drive cylinder 12 is arranged on each of the front and rear sides of each pressure plate unit 113. Correspondingly, the locking member 2 has a socket 231 extending in the left-to-right direction, and the piston rod of the drive cylinder 12 can be connected to the socket 231.

[0057] In one specific embodiment, the substrate 111 is further provided with a limiting block 114, and the limiting block 114 is provided with a guide hole; the locking member is fixedly connected with a fixing sleeve 115, and the fixing sleeve 115 is engaged with the guide hole.

[0058] Specifically, the guide hole is set along the front-to-back direction. One end of the fixed sleeve is closed, and the other end is open, with the open end inserted into the free end of the piston rod of the drive cylinder 12.

[0059] When the pressure plate unit 113 comes into contact with the power supply busbar 400, the piston rod of the drive cylinder 12 drives the fixed sleeve to pass through the insertion hole 231 and the guide hole.

[0060] The limiting block 114 and the fixing sleeve 115 are used to reduce the stress on the drive cylinder 12 and extend its service life. Furthermore, since the fixing sleeve 115 is provided on the output shaft of the drive cylinder 12, direct connection between the output shaft and the guide hole on the limiting block 114 is avoided, reducing wear on the output shaft. Additionally, because the distance between the limiting block 114 and the drive cylinder 12 is relatively small, the drive cylinder 12 must be installed first, and then the fixing sleeve 115 must be screwed on from both sides. This ensures the smooth installation of the fixing sleeve 115.

[0061] Please see Figure 4 and Figure 7One embodiment of this application discloses a power transmission vehicle 100, which includes: a vehicle body 30, an electrode clamping mechanism 20, and a pressure plate assembly 11 device according to any of the above embodiments. The electrode clamping mechanism 20 is disposed on the vehicle body 30, and the pressure plate assembly 11 is disposed on the electrode clamping mechanism 20. The pressure plate device 10 is used to connect to the power transmission busbar 400, and the electrode clamping mechanism 20 is used to connect to the conductive electrode of the graphitization furnace.

[0062] In addition, the vehicle body 30 is equipped with a sliding device 40 and a lifting device 50. The sliding device 40 is fixed on the vehicle body 30. The sliding device 40 drives the electrode clamping mechanism 20 to move to one side of the power transmission vehicle 100, thereby moving closer to or away from the graphitization furnace, so as to achieve the purpose of connecting or disconnecting the electrode clamping mechanism 20 from the conductive electrode on the end wall of the graphitization furnace.

[0063] The lifting device 50 is connected to the electrode clamping mechanism 20 via the sliding device 40 to adjust the height of the electrode clamping mechanism 20, thereby accommodating the graphitization furnace with conductive electrodes of different heights.

[0064] When the power supply vehicle 100 needs to supply power to the graphitization furnace, the lifting device 50 drives the electrode clamping device to move up and down until it is at the same height as the graphitization furnace. Then, the sliding device 40 is controlled to move the electrode clamping mechanism 20 toward the graphitization furnace until the electrode clamping mechanism 20 can dock with the conductive electrode of the graphitization furnace. After that, the pressure plate device 10 is controlled to connect to the power supply busbar 400.

[0065] After the power supply trolley 100 finishes supplying power to the graphitization furnace, the pressure plate device 10 descends to separate from the power supply busbar 400, and the sliding seat drives the electrode clamping mechanism 20 to move away from the graphitization furnace. The power supply trolley 100 can then move to the furnace position of the next graphitization furnace to supply power to that furnace.

[0066] In this embodiment, the power transmission vehicle 100 employs a pressure plate device 10. Through the cooperation of locking element one and locking element two, the pressure plate device 10 and the power transmission busbar 400 are always connected. The connection between the pressure plate assembly 11 and the power transmission busbar is more stable, making the power transmission vehicle 100 supply power to the graphitization furnace more stable.

[0067] Please see Figure 1 and Figure 5 One embodiment of this application also discloses a locking frame 200. For a description of the orientation of the locking frame 200 (e.g., up / down, left / right, front / back), please refer to... Figure 1 The coordinate system in the diagram. Locking frame 200 is connected to power busbar 400 (see...). Figure 7 It is suspended at a certain height.

[0068] In one specific embodiment, the locking frame 200 includes: a frame body and a second locking member fixed to the frame body, the second locking member being used to cooperate with any of the first locking members described above;

[0069] The locking frame 200 of this application is equipped with a second locking element. When the pressure plate assembly 11 rises to a preset position and contacts the power supply busbar 400, the first locking element and the second locking element cooperate to lock the pressure plate assembly 11 at a fixed height and keep it connected to the power supply busbar 400, thereby ensuring a stable and reliable connection between the pressure plate and the power supply busbar 400. Even in the event of a hydraulic system failure, the pressure plate will not fall.

[0070] In this embodiment, the second locking element has a front-to-back insertion hole 231. The first locking element is a drive cylinder 12, whose piston rod extends or retracts in the front-to-back direction.

[0071] The specific forms of locking element one and locking element two have been described in relation to pressure plate device 10, and will not be repeated here.

[0072] In one specific embodiment, the frame includes a connecting frame 210 connected to the power supply busbar 400 and a bottom frame 220 connected to the bottom of the connecting frame 210; a second locking element is provided on the bottom frame 220.

[0073] Specifically, a frame includes four connecting frames 210, which are arranged in a straight line along the left and right direction. The connecting frames 210 are inverted U-shapes and are attached to the power supply busbar 400. When installing the frame, the connecting frames 210 are first installed on the power supply busbar 400, and then the bottom frame 220 is installed on the connecting frames 210.

[0074] The bottom frame 220 is rectangular, and the rectangle is formed by a horizontal plate 221 and a vertical plate 222. The locking element is located on the upper horizontal plate, and the insertion hole 231 extends in the front-to-back direction.

[0075] Please see Figure 6 In one embodiment of this application, a power supply busbar device is also disclosed, including: a power supply busbar, a busbar support 300 and a locking frame 200 as described above, wherein the power supply busbar is disposed on the busbar support 300; and the locking frame 200 is suspended on the power supply busbar.

[0076] Among them, the busbar support 300 consists of multiple gantry frames, which are used to place and fix the power supply busbar. In this embodiment, the power supply busbar is used as the power supply busbar 400.

[0077] Since the power supply busbar device of this embodiment adopts the locking frame 200 of the above embodiment, it can lock and position the pressure plate device 10 of the power supply vehicle 100, so that the pressure plate device 10 is always kept in contact with the power supply busbar, thereby ensuring the stability of the power supply vehicle 100 to the power supply busbar.

[0078] 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.
