However, in actual use, the power transmission busbar is fixed by a busbar mounting frame, and the busbar connection assembly abuts against the power transmission busbar, so that the power transmission vehicle can draw electricity from the power transmission busbar. When the power transmission busbar is pushed on the top of the power transmission vehicle, the power transmission busbar will also push the power transmission vehicle back, resulting in excessive internal stress in the power transmission vehicle and a short service life.

DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] In the scenario where a power transmission vehicle transmits electricity to a graphitization furnace, there are usually multiple graphitization furnaces, a power transmission vehicle, and a power transmission aluminum busbar. The graphitization furnace has two end walls, and the power transmission vehicle is located at one end of one of the end walls of the graphitization furnace and keeps a certain distance from the graphitization furnace. The power transmission vehicle can move along the direction in which the multiple graphitization furnaces are arranged. The power transmission aluminum busbar is arranged around the multiple graphitization furnaces and is arranged at a certain height from the ground. Specifically, the power transmission vehicle is located directly below the power transmission aluminum busbar, and the distance between the power transmission busbar and the ground allows the power transmission vehicle to pass.

[0035] See also Figure 1 to Figure 3 , Figure 5 and Figure 6 One embodiment of the present application provides a platen device 10 for a power transmission vehicle 100. For a description of the orientation of the platen device 10 (such as up and down, left and right, front and back), see Figure 1 The platen device 10 comprises:

[0036] A pressing plate assembly 11 that can be raised and lowered relative to the power transmission busbar 400;

[0037] The pressure plate assembly 11 is fixedly connected with a plurality of locking members 1 that can be extended forward and backward. When the pressure plate assembly 11 rises to contact the power transmission busbar 400, the locking member 1 cooperates with a plurality of locking members 2 fixed at a preset height to limit the pressure plate assembly 11 at a preset height position.

[0038] The pressure plate device 10 of the present application includes a locking member 1, which is connected with a locking member 2 fixed at a preset height through the locking member 1, so that the pressure plate assembly 11 is locked and fixed at a preset height position. That is, the pressure plate assembly 11 is fixed to the power transmission bus 400 through the cooperation of the locking member 1 and the locking member 2, so as to convert the reaction force of the power transmission bus 400 on the pressure plate assembly into the internal force of the power transmission bus 400, reduce the force borne by the power transmission vehicle 100, and improve the service life of the power transmission vehicle.

[0039] In addition, when the pressure plate assembly 11 rises to a preset position and contacts the power transmission busbar 400, the locking member 1 and the locking member 2 are connected to each other, so that the pressure plate assembly 11 is locked at a fixed height and is always connected to the power transmission busbar 400, thereby ensuring a stable and reliable connection between the pressure plate and the power transmission busbar 400. Even if a hydraulic system failure occurs, the pressure plate will not fall off.

[0040] The pressure plate assembly 11 is driven by a driving member to move up and down. It can be understood that the pressure plate assembly must be driven by a driving member to achieve up and down movement (described in detail below). Specifically, when the power transmission vehicle 100 needs to transmit electricity, the driving member drives the pressure plate assembly 11 to move upward until the pressure plate assembly 11 contacts the power transmission busbar 400; when the power transmission vehicle 100 completes power transmission and is ready to transmit electricity to the next graphitization furnace, the driving member drives the pressure plate assembly 11 to move downward until it is separated from the power transmission busbar 400. Among them, the power transmission busbar 400 can be a power transmission aluminum busbar, which is always directly above the pressure plate assembly 11.

[0041] In this embodiment, the tightening cylinder 112 is used as a driving member.

[0042] A plurality of locking members 2 are fixed to the power transmission busbar 400, so when the locking member 1 cooperates with the locking member 2, the locking member 1 is indirectly fixed to the power transmission busbar 400 through the locking member 2. Of course, the locking member can also be fixed to the ceiling or the side wall.

[0043] In a specific embodiment, the first locking member includes a positioning pin 121, which moves forward and backward under the drive of the driving cylinder 12; the second locking member includes a plug-in member 230, which is provided with a socket 231 that matches the positioning pin 121.

[0044] In this embodiment, the piston rod of the oil cylinder is used as the positioning pin 121. In the initial state, the piston rod of the driving oil cylinder 12 is retracted in the cylinder body of the driving oil cylinder 12. When the pressure plate assembly 11 contacts the power transmission busbar 400, the piston rod of the driving oil cylinder 12 is controlled to extend from the cylinder body to the socket 231 of the connector 230. When the power transmission is completed, the piston rod of the driving oil cylinder 12 is controlled to retract back into the cylinder body, so that the pressure plate assembly 11 can be driven by the tightening oil cylinder 112 to perform a downward movement, which is convenient for the movement of the power transmission vehicle 100. The combined structure of the positioning pin 121 and the connector 230 is simple and has a good fixing effect.

[0045] It can be understood that the locking member 1 can also be set as the plug-in member 230 , and the locking member 2 can be set as the driving cylinder 12 .

[0046] In fact, when the pressure plate assembly 11 contacts the power transmission busbar 400, the locking member 1 and the locking member 2 cooperate with each other to fix the aluminum busbar assembly to a specified height. Then, the locking member 1 and the locking member 2 are not limited to the form of the positioning pin 121 and the plug-in member 230.

[0047] Exemplarily, the first locking member is a handle, and the second locking member is a clamping body, which is fixed on the power transmission busbar 400. When the pressure plate assembly 11 moves to contact the power transmission busbar 400, the clamping body is controlled to clamp the handle to achieve fixation.

[0048] Furthermore, there are two connectors 230 ; the positioning cylinder comprises a double extension cylinder, and the two piston rods of the double extension cylinder are respectively connected with the two connectors 230 .

[0049] It should be noted that the double extension oil cylinder is an oil cylinder having a cylinder body, and two piston rods located on the same straight line are arranged on the cylinder body. The two piston rods of the double extension oil cylinder extend or retract in the front-to-back direction. Correspondingly, the plug-in 230 is also distributed in the front-to-back direction, and the plug-in 230 is provided with a plug hole 231 in the front-to-back direction.

[0050] When the pressure plate device 10 contacts the power transmission busbar 400, the two piston rods of the double-extension cylinder are controlled to extend into the sockets 231 of the two connectors 230 respectively. The double-extension cylinder is connected with the two connectors 230 through the two piston rods, thereby improving the reliability of the position fixation of the pressure plate device 10.

[0051] In other embodiments, the driving cylinder 12 may be two one-way cylinders arranged in opposite directions, or only one one-way cylinder may be provided to cooperate with one connector 230. Compared with the one-way cylinder, the double extension cylinder does not need to be synchronously set, so that the movement stroke of the two piston rods can be consistent, which is easy to use.

[0052] In a specific embodiment, the pressure plate assembly 11 includes: a base plate 111, a tightening oil cylinder 112 and a pressure plate unit 113; the cylinder body of the tightening oil cylinder 112 is connected to the base plate 111, and the piston rod of the tightening oil cylinder 112 is connected to the pressure plate unit 113; one pressure plate unit 113 corresponds to multiple tightening oil cylinders 112. The base plate 111 serves as a mounting carrier for the tightening oil cylinder 112 and the driving oil cylinder 12.

[0053] In this embodiment, three pressure plate units 113 are arranged along the left and right directions, and each pressure plate is equipped with four tightening cylinders 112. Specifically, the piston rods of the four tightening cylinders 112 are respectively in contact with the four corners of the lower surface of the pressure plate assembly 11. In order to make the thrust more uniform, a tightening block can also be provided at one end of the output shaft of the tightening cylinder 112, and the tightening block contacts the lower surface of the pressure plate assembly 11. As one of the driving parts, the tightening cylinder 112 can drive the push plate unit to rise and fall, so as to realize the contact or separation between the push plate unit and the power transmission busbar 400.

[0054] Of course, the number of the pressure plate units 113 and the number and positions of the top oil cylinders can be adaptively adjusted to meet actual usage requirements.

[0055] In a specific implementation, there are a plurality of driving cylinders 12 and a plurality of pressing plate units 113 , and the driving cylinders 12 are disposed on the left and right sides of the pressing plate units 113 .

[0056] In this embodiment, since the three platen units 113 and the four driving cylinders 12 are alternately distributed in the left-right direction, the left and right sides of each platen unit 113 are provided with a driving cylinder 12. Such a positional layout of the driving cylinder 12 and the platen unit 113 can make each platen unit 113 have a driving cylinder 12 on both sides, and two adjacent platen units 113 can share one driving cylinder 12.

[0057] It should be noted that the driving cylinder 12 is fixed to the base plate 111 through the cylinder mounting seat 122 and is arranged in the front-to-back direction, that is, the piston rod of the driving cylinder 12 extends or retracts from the front-to-back direction. In other embodiments, the driving cylinder 12 can also be arranged in the left-right direction, that is, the output shaft extends or retracts in the left-to-right direction. A driving cylinder 12 is arranged on the front and back 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 driving cylinder 12 can be connected with the socket 231.

[0058] In a specific embodiment, a limit block 114 is further provided on the base plate 111 , and a guide hole is opened on the limit block 114 ; the locking member is fixedly connected with a fixing sleeve 115 , and the fixing sleeve 115 is matched and connected with the guide hole.

[0059] Specifically, the guide hole is arranged along the front-rear direction. One end of the fixed sleeve is closed, and the other end is open, and the free end of the piston rod of the driving oil cylinder 12 is inserted through the open end.

[0060] When the pressing plate unit 113 contacts the power transmission busbar 400 , the piston rod of the driving cylinder 12 drives the fixing sleeve to pass through the insertion hole 231 and the guide hole in turn.

[0061] The limit block 114 and the fixed sleeve 115 are used for structural stress to reduce the stress on the driving cylinder 12, so as to increase the service life of the driving cylinder 12. In addition, since the fixed sleeve 115 is provided on the output shaft of the driving cylinder 12, it is possible to avoid the output shaft of the driving cylinder 12 being directly connected to the guide hole on the limit block 114, so as to reduce the wear of the output shaft. In addition, since the distance between the limit block 114 and the driving cylinder 12 is relatively small, the driving cylinder 12 needs to be installed first and then the fixed sleeve 115 is screwed on from both sides, so that the installation of the fixed sleeve 115 can be completed smoothly.

[0062] See also Figure 4 and Figure 8An embodiment of the present 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 of any of the above embodiments, wherein 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 a power transmission busbar 400, and the electrode clamping mechanism 20 is used to connect to a conductive electrode of a graphitization furnace.

[0063] In addition, a sliding device 40 and a lifting device 50 are provided on the vehicle body 30. The sliding device 40 is fixed on the vehicle body 30, and the sliding device 40 drives the electrode clamping mechanism 20 to move toward 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 with the conductive electrode of the end wall of the graphitization furnace.

[0064] The lifting device 50 is connected to the electrode clamping mechanism 20 through the sliding device 40 to adjust the height of the electrode clamping mechanism 20, so as to meet the alignment of the graphitization furnace with conductive electrodes of different heights.

[0065] When the power transmission vehicle 100 needs to transmit 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 drive the electrode clamping mechanism 20 to move toward the graphitization furnace until the electrode clamping mechanism 20 can dock with the conductive electrode of the graphitization furnace. Then, the pressing plate device 10 is controlled to connect with the power transmission busbar 400.

[0066] When the power transmission vehicle 100 finishes transmitting power to the graphitization furnace, the pressing plate device 10 descends to separate from the power transmission busbar 400, and the sliding seat drives the electrode clamping mechanism 20 to move away from the graphitization furnace. The power transmission vehicle 100 can then move to the furnace position of the next graphitization furnace to transmit power to the graphitization furnace.

[0067] In this embodiment, the power transmission vehicle 100 uses a pressure plate device 10, and the pressure plate device 10 is connected to the power transmission busbar 400 by the cooperation of the locking member 1 and the locking member 2 in the pressure plate device 10. The connection between the pressure plate assembly 11 and the power transmission aluminum busbar is more stable, so that the power transmission vehicle 100 can transmit power to the graphitization furnace more stably.

[0068] See also Figure 1 , Figure 5 and Figure 6 In one embodiment of the present application, a locking frame 200 is also disclosed. For a description of the orientation of the locking frame 200 (such as up and down, left and right, front and back), please refer to Figure 5 The locking frame 200 is connected to the power bus 400 (see Figure 8 ) is hung at a certain height.

[0069] In a specific embodiment, the locking frame 200 includes: a frame body and a locking member 2 fixed to the frame body, the locking member 2 is used to cooperate with any of the above-mentioned locking members 1;

[0070] The locking frame 200 of the present application is provided with a locking member 2. When the pressure plate assembly 11 rises to a preset position and contacts the power transmission busbar 400, the locking member 1 and the locking member 2 are connected to each other, so that the pressure plate assembly 11 is locked at a fixed height and is always connected to the power transmission busbar 400, thereby ensuring that the connection between the pressure plate and the power transmission busbar 400 is stable and reliable. Even if a hydraulic system failure occurs, the pressure plate will not fall off.

[0071] In this embodiment, the second locking member has a front-to-back direction insertion hole 231. The first locking member is a driving oil cylinder 12, and the piston rod of the driving oil cylinder 12 extends or retracts along the front-to-back direction.

[0072] The specific forms of the locking member 1 and the locking member 2 have been embodied in the pressing plate device 10 and will not be repeated here.

[0073] In a specific embodiment, the frame includes a connection frame 210 connected to the power transmission busbar 400 and a bottom frame 220 connected to the bottom of the connection frame 210 ; the second locking member is disposed on the bottom frame 220 .

[0074] Specifically, a frame includes four connection frames 210, which are arranged in a straight line along the left and right directions. The connection frame 210 is in an inverted U-shape and buckled on the power transmission busbar 400. When installing the frame, the connection frame 210 is first installed on the power transmission busbar 400, and then the bottom frame 220 is installed on the connection frame 210.

[0075] The bottom frame 220 is a rectangle, which is enclosed by a horizontal plate 221 and a vertical plate 222. The two horizontal plates of the locking member are arranged on the top, and the insertion hole 231 extends along the front-back direction.

[0076] See also Figure 7 In one embodiment of the present application, a power transmission busbar device is also disclosed, including: a power transmission aluminum busbar, a busbar bracket 300 and the above-mentioned locking frame 200, the power transmission aluminum busbar is arranged on the busbar bracket 300; the locking frame 200 is suspended on the power transmission aluminum busbar.

[0077] The busbar support 300 is a plurality of gantry frames, and the busbar support is used to place and fix the power transmission aluminum busbar. In this embodiment, the power transmission aluminum busbar is used as the power transmission busbar 400.

[0078] Since the power transmission aluminum bar device of this embodiment adopts the locking frame 200 of the above-mentioned embodiment, it can lock and position the pressure plate device 10 of the power transmission vehicle 100, so that the pressure plate device 10 always remains in contact with the power transmission aluminum bar, thereby ensuring the stability of the power transmission aluminum bar of the power transmission vehicle 100.

[0079] 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.
