Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of graphitization furnaces, in particular to a push-type conductive device. Background Art
[0002] With the development of the economy and the continuous changes in energy structure, AC graphitization furnaces are used more and more in industrial production. Conductive devices are one of the important equipment necessary in the production process. The convenience and reliability of conductive devices are particularly important in production.
[0003] AC graphitization furnaces operate intermittently. A single production cycle involves loading, powering on, cooling, unloading, and overhauling, taking a total of 12 to 15 days, with powering on for only 3 to 5 days. Generally, one transformer can be used to power 5 to 7 furnaces of the same specifications, forming a furnace group, which is a production unit. During production, the transformer operates continuously, and the furnaces operate in turns. Typically, one furnace in a furnace group is powered on, while the others are being loaded, cooled, loaded, unloaded, or overhauled. After one furnace is finished operating, power is supplied to the next. The conductive device connects the furnace head electrode of the furnace to be put into operation to the busbar as needed. After heating is complete, the conductive device disconnects the furnace head electrode from the busbar and moves to the next furnace to be operated, connecting the furnace head electrode and busbar.
[0004] Existing conductive devices usually use a fixed conductive method, such as clamping conduction. Although this method is reliable, it has some limitations in practical applications: in high temperature or high vibration environments, clamping conduction may cause unstable power transmission due to poor contact; clamping connection is difficult to adapt to changing environmental conditions, such as high temperature and vibration, which limits the application range of the conductive device. Furthermore, the maintenance of clamping conduction is relatively complicated, requiring regular inspection and replacement of worn parts, which increases maintenance costs. On the other hand, existing conductive devices do not have self-adjustment capabilities, which results in the connection plate and the busbar connection part and the graphitization furnace connection part not being tightly fitted, which in turn causes an increase in resistance at the joint, increases heat generation, reduces conductive efficiency, and affects energy utilization efficiency. At the same time, it also applies a bias load to the busbar connection part or the graphitization furnace connection part, causing them to be damaged.
[0005] In order to solve the above technical problems, the present invention designs a push-type conductive device. Utility Model Content
[0006] The utility model provides a push-type conductive device, which aims to solve the problem that existing conductive devices do not have self-adjustment capabilities and the clamping type power connection method is difficult to adapt to changing environmental conditions. The technical solution is as follows:
[0007] A push-type conductive device includes a support vehicle body, a support component, and a first power connection module disposed on the support component.

The connector is made of a flexible conductive material and is mounted on the support vehicle body. A drive device for driving the power connection device to open and close is provided on the support component.
[0008] The supporting vehicle body includes a vehicle body plate and supporting wheels. The bottom of the vehicle body plate is fixedly connected to the supporting wheels.

[0016] Beneficial effects
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: on the one hand, the fitted power connection method can significantly improve the stability and efficiency of power transmission by increasing the contact area and optimizing the contact pressure distribution.

[0027] The present invention will be further described below with reference to the accompanying drawings and examples:
[0028] The following describes embodiments of the present invention in detail. 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 having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, a push-type conductive device is characterized by comprising a supporting vehicle body 3, a supporting component and a first power connection module 4 provided on the supporting component;
[0032] like Figure 3 As shown, the first power connection module 4 includes a first power connection board 41, a connector 43 and a second power connection board 44. The two ends of the connector 43 are connected to the first power connection board 41 and the second power connection board 44 respectively through a connecting plate 42. The connector 43 is made of a flexible conductive material and is installed on the supporting vehicle body 3. The supporting component is provided with a driving device for driving the power connection device to open and close.
[0033] like Figure 5 As shown, the support vehicle body 3 includes a vehicle body panel 31 and support wheels 32. The support wheels 32 are fixedly connected to the bottom of the vehicle body panel 31. A first support column 33 and a second support column 34 are fixedly connected to the vehicle body panel 31. The support wheels 32 are universal wheels. The first and second support columns 33 and 34 provide stability and support for the first power connection module. These columns ensure the flexible portion remains in the correct position, preventing deviation or swinging caused by external factors such as vibration or wind. This helps reduce vibration in the flexible portion, thereby minimizing electrical connection issues caused by vibration, such as poor contact or disconnection.
[0034] The connector 43 is made of flexible copper tape. This flexible material is primarily used to adjust the distance between connections, ensuring a good electrical connection under various operating conditions. The connector 43 can be stretched or tightened as needed to accommodate connections at different locations, ensuring the free movement of the connection trolley on the track. By allowing a certain degree of displacement, the flexible connector 43 ensures a stable electrical connection even with minor structural changes within the furnace.
[0035] like Figure 4 As shown, the first power connection module 4 further includes a cooling water tank 46 , which is disposed on the back of the first power connection board 41 and the second power connection board 44 .
[0036] The cooling water tank 46 has a water inlet and a water outlet and includes a plurality of staggered partitions 411. The cooling water tank 46 helps regulate the temperature of the first power connection module 4. Especially in high-temperature environments, the cooling water tank 46 can effectively absorb and dissipate heat, keeping the first power connection module 4 operating within a suitable temperature range.
[0037] The drive device is an opposed dual-piston cylinder or two single-piston cylinders with opposite directions. The opposed dual-piston cylinder's two piston rod output ends are connected to the first and second connection plates 41 and 44, respectively. The opposed dual-piston cylinder's internal structure features two pistons arranged face-to-face, sharing a common hollow cylinder barrel. When hydraulic oil is input into one end of the cylinder, the corresponding piston is pushed forward, while the piston at the other end moves in the opposite direction due to spring force or other reaction force. This design enables the opposed dual-piston cylinder to achieve bidirectional synchronous motion, meaning that the two pistons can extend and retract simultaneously and relative to each other. Placing both pistons within the same cylinder significantly reduces the required installation space. The opposed dual-piston cylinder is mounted on a support component, with the free ends of the two piston rods driving the support plate 21 and the first and second connection plates 41 and 44 to move in close contact with the busbar and electrodes.
[0038] When the driving device is two single-piston oil cylinders with opposite directions, the free ends of the piston rods of the two single-piston oil cylinders are connected to the first power connection plate 41 and the second power connection plate 44 respectively.
[0039] like Figure 6 As shown, the supporting component is an upper supporting body 6, which includes a supporting body 2, an upper supporting beam 61 and a pulley 63. The supporting body 2 is connected to a sliding mounting seat 62, the pulley 63 is rollingly connected to the sliding mounting seat 62, and the pulley 63 is slidingly connected to the supporting beam 61.
[0040] like Figure 7As shown, the supporting component is a lower supporting body, and the lower supporting body includes a supporting body 2 and a lower supporting wheel 22 . The bottom of the supporting body 2 is connected to the lower supporting wheel 22 .
[0041] The supporting component may also have both upper and lower supports to make the first power connection module 4 move more smoothly.
[0042] The support component includes a support body 2, a sliding mount 62, and a pulley 63. The bottom of the support body 2 is connected to the lower support wheel 22, and the top of the support body 2 is connected to the sliding mount 62. The pulley 63 is in rolling connection with the sliding mount 62 and in sliding connection with the support beam 61. The lower support wheel 22 is a fixed wheel. A circular hole is defined in the support body 2 to allow the drive device to extend.
[0043] The support wheels 32 are universal wheels, providing omnidirectional mobility. The lower support wheels 22 are fixed wheels, also known as guide wheels, primarily responsible for guiding the push-pull power connection mechanism in a specific direction. If both the support wheels 32 and the lower support wheels 22 are fixed wheels, a misalignment in direction could cause the first power connection module 4 to become stuck, rendering it unable to move. Therefore, the combination of universal and fixed wheels reduces maintenance costs by minimizing issues caused by improper steering or inaccurate positioning.
[0044] like Figure 8 As shown, the busbar connection a and the graphitization furnace connection b are positioned opposite each other, with the conductive device c positioned between them. The first connection module 4 is aligned with the busbar connection a and the graphitization furnace connection b, and the opposing dual-piston cylinders operate, driving the first and second connection plates 41, 44 to align closely with the busbar connection a and the graphitization furnace connection b. As the first and second connection plates 41, 44 engage, the support wheels 32 and lower support wheels 22 move, providing good guidance and smooth alignment. The connector 43 is made of flexible copper strip and possesses a certain degree of deformability. This allows for a certain degree of deformation when the busbar connection a and the graphitization furnace connection b are not precisely aligned, such as when they are not completely aligned. This allows for better alignment of the first and second connection plates 41, 44, with the busbar connection a and the graphitization furnace connection b.
[0045] The flexible connector 43 can compensate for displacement caused by mechanical vibration or movement through its own deformation, thereby maintaining the stability of the connection. When the connection surface is not completely flat, the connector 43 can adapt to the surface changes through its own deformation, ensuring good contact even on uneven surfaces.
[0046] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
