Description

Technical Field

[0001] This invention relates to the field of graphite electrode clamping technology, and more particularly to an adaptive clamp, an electrode clamping mechanism, and a power transmission vehicle. Background Technology

[0002] In the Atchison graphitization furnace apparatus, two power supply cars continuously move to supply power to different Atchison graphitization furnace groups. Referring to CN115200364A, firstly, the first power supply car moves precisely along the track to a specific furnace position within the Atchison graphitization furnace group requiring power. Then, the busbar connecting mechanism on the first power supply car clamps the two sides of the first busbar, and simultaneously, the electrode clamping mechanism on the first power supply car clamps the two sides of the furnace head electrode. Similarly, the second power supply car moves precisely along the track to the symmetrical end of a specific furnace position within the Atchison graphitization furnace group requiring power. Then, the busbar clamping mechanism on the second power supply car clamps the two sides of the second busbar, and simultaneously, the electrode clamping mechanism on the second power supply car clamps the two sides of the furnace tail electrode.

[0003] However, when the electrode clamping mechanism clamps the furnace head electrode or furnace tail electrode, the furnace head electrode or furnace tail electrode may be deflected in various directions. During the clamping process, the furnace head electrode or furnace tail electrode is prone to breakage, resulting in a short service life of the electrode.

[0004] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0034] The technical solution of the present invention 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 the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Embodiments of the present invention 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.

[0036] Example 1

[0037] Please see Figure 1 This embodiment discloses a power supply vehicle 100 for supplying power to the Atchison graphitization furnace. The power supply vehicle 100 includes: a vehicle body 10, a frame 20, an electrode clamping mechanism 30, a busbar clamping mechanism 40, and a conductive cable 50. The frame 20 is mounted on the vehicle body 10, the electrode clamping mechanism 30 is mounted on the vehicle body 10, and the busbar clamping mechanism 40 is mounted on the frame 20. The electrode clamping mechanism 30 and the busbar clamping mechanism 40 are electrically connected through the conductive cable 50.

[0038] Among them, the electrode clamping mechanism 30 is used to clamp the graphite electrode on the side of the Atchison graphitization furnace, and the busbar clamping mechanism 40 is used to clamp the aluminum ingot on the top of the Atchison graphitization furnace.

[0039] For ease of understanding, the power supply vehicle 100 can be regarded as a movable switch. When an Atchison graphitization furnace needs to be powered, the power supply vehicle 100 moves to the front or rear of the Atchison graphitization furnace, the electrode clamping mechanism 30 clamps the graphite electrode of the Atchison graphitization furnace, and the busbar clamping mechanism 40 clamps the aluminum ingot of the Atchison graphitization furnace, thus realizing the power supply of the Atchison graphitization furnace.

[0040] Example 2

[0041] Please refer to Figure 2 This embodiment discloses an electrode clamping mechanism 30, used on the trolley 100 of Embodiment 1. The electrode clamping mechanism 30 includes:

[0042] Adaptive clamp 31; and

[0043] The support column 32 and the adaptive clamp 31 are mounted on the support column 32.

[0044] The device includes three support columns 32, spaced apart along the length of the frame; each support column 32 is equipped with three adaptive clamps 31, which are distributed along the length of the support column 32. This electrode clamping mechanism 30 is suitable for an Atchison graphitization furnace with three rows of graphite electrodes, each row containing three electrodes.

[0045] Of course, the applicant can also freely configure the number of support columns 32 and the number of adaptive clamps 31 on each support column 32 according to the implementation and usage requirements.

[0046] When the graphite electrode is not inserted, the opening direction of the adaptive fixture 31 is in the same direction, that is, towards the Atchison graphitization furnace.

[0047] In one specific embodiment, the support column 32 includes a column body 321, a first support portion 322 and a second support portion 323, with the first support portion 322 and the second support portion 323 arranged along the length direction of the column body 321.

[0048] Please see Figure 2 and Figure 3 The adaptive clamp 31 is provided with a first transmission rod 315 and a second transmission rod 316. The first transmission rod 315 is provided on the first support part 322, and the second transmission rod 316 is provided on the second support part 323.

[0049] By providing a first support portion 322 and a second support portion 323, the adaptive clamp 31 is mounted on the support column 32.

[0050] The first transmission rod 315 is fixedly connected to the first support part 322, and the second transmission rod 316 is fixedly connected to the second support part 323.

[0051] In other embodiments, the first transmission rod 315 may also be configured to be slidably connected to the first support portion 322, and the second transmission rod 316 may be configured to be slidably connected to the second support portion 323. This allows the adaptive clamp 31 to move relative to the support column 32 to accommodate changes in the position of the graphite electrode.

[0052] Specifically, a dovetail groove (not shown in the figure) is formed on the second support 323 along the opening direction of the adaptive clamp 31. The adaptive clamp 31 is provided with a second transmission rod 316, which is located in the dovetail groove. As the slider slides in the dovetail groove, the adaptive clamp 31 can move closer to or further away from the column 321 to cope with scenarios where the graphite electrode does not extend sufficiently into the adaptive clamp 31 or extends too deeply.

[0053] Example 3

[0054] Please see Figures 3 to 6This embodiment discloses an adaptive fixture 31, comprising:

[0055] Clamp; and

[0056] An adaptive device is configured on the clamp to control the clamp to produce the same deflection as the graphite electrode.

[0057] By setting an adaptive device on the clamp, the adaptive device can control the clamp to follow the electrode tilt and produce the same tilt, so that the clamp is always in contact with the electrode, the electrode is held stably and reliably, the electrode is not easy to break, and the service life is long.

[0058] Specifically, the adaptive device includes a first adaptive component and a second adaptive component.

[0059] In other embodiments, the adaptive device may consist of only a first adaptive component and a second adaptive component.

[0060] This embodiment takes a combination that simultaneously has a first adaptive component and a second adaptive component as an example.

[0061] Please see Figure 3 In one specific embodiment, the first adaptive component includes a first clamping plate 311, a first clamping arm 313, a second clamping plate 312 and a second clamping arm 314, wherein the first clamping plate 311 is hinged to the first clamping arm 313, and the second clamping plate 312 is hinged to the second clamping arm 314.

[0062] The intersection of the first clamping plate 311 and the first clamping arm 313 forms the first hinge point and the second hinge point, which together form the first pivot. The first clamping plate 311 rotates around the first pivot. The intersection of the second clamping plate 312 and the second clamping arm 314 forms the third hinge point and the fourth hinge point, which together form the second pivot. The first clamping plate 311 rotates around the second pivot.

[0063] The graphite electrode is a square prism 321, with one end of the square prism 321 inserted into the opening of the adaptive clamp 31.

[0064] When the graphite electrode is inserted into the opening of the adaptive clamp 31 at an angle in the front-back direction, the first clamp 311 flips along the first axis and the second clamp 312 flips along the second axis, so that the first clamp 311 and the second clamp 312 are always firmly attached to both sides of the graphite electrode, and the clamping is stable and reliable.

[0065] The front-back direction of the graphite electrode refers to the opening direction of the adaptive fixture 31.

[0066] Please continue reading. Figure 3For example, when the graphite electrode is tilted counterclockwise in the front-back direction, the first clamping plate 311 rotates counterclockwise about the first pivot, and the second clamping plate 312 rotates counterclockwise about the second pivot. Conversely, when the graphite electrode is tilted clockwise in the front-back direction, the first clamping plate 311 rotates clockwise about the first pivot, and the second clamping plate 312 rotates clockwise about the second pivot.

[0067] The degree of deflection of the first clamping plate 311 and the second clamping plate 312 is the same as the degree of deflection of the graphite electrode. For example, if the graphite electrode is deflected by 10°, the first clamping plate 311 and the second clamping plate 312 will also be rotated by 10°.

[0068] Please see Figure 4 In one specific embodiment, the second adaptive component includes: a first clamping arm 313, a second clamping arm 314, and a drive member 317, one end of the drive member 317 being hinged to the first clamping arm 313, and the other end of the drive member 317 being hinged to the second clamping arm 314.

[0069] Specifically, the driving member 317 has two collars 3171 and 3172 at both ends. One collar 3171 is fitted onto the second post 3136 of the first clamping arm 313, and the other collar 3172 is fitted onto the fourth post 3146 of the second clamping arm 314. That is, one end of the driving member 317 can rotate about the third post 3145, and the other end can rotate about the fourth post 3146. The second post 3136 and the fourth post 3146 will be described below.

[0070] For example, the drive unit 317 is a cylinder, a hydraulic cylinder, or a linear motor.

[0071] Specifically, when the output shaft of the drive member 317 extends, the first clamping arm 313 rotates clockwise relative to the drive member 317, thereby causing the first clamping plate 311 to move away from the second clamping plate 312. Conversely, when the output shaft of the drive member 317 shortens, the first clamping arm 313 moves counterclockwise relative to the drive member 317, thereby causing the first clamping plate 311 to move closer to the second clamping plate 312.

[0072] In one specific embodiment, the second adaptive component includes: a first clamping arm 313, a second clamping arm 314, and a first transmission rod 315, one end of the first transmission rod 315 being hinged to the first clamping arm 313, and the other end of the first transmission rod 315 being hinged to the second clamping arm 314.

[0073] When the first clamping arm 313 is driven by the drive member 317 to swing, the second clamping arm 314 swings in the same direction as the first clamping arm 313.

[0074] Please see Figure 3For example, under the driving action of the driving member 317, the first clamping arm 313 rotates counterclockwise relative to the driving member 317, and drives the second clamping arm 314 to rotate counterclockwise relative to the driving member 317 through the first transmission rod 315. Moreover, the first clamping arm 313 and the second clamping arm 314 rotate by the same amount.

[0075] Based on the first transmission rod 315, the second adaptive component further includes a second transmission rod 316, which is located below the first transmission rod 315. One end of the second transmission rod 316 is hinged to the first clamping arm 313, and the other end of the first transmission rod 315 is hinged to the second clamping arm 314.

[0076] Compared to simply setting the first transmission rod 315, setting both the first transmission rod 315 and the second transmission rod 316 makes the power transmission from the first clamping arm 313 to the second clamping arm 314 more even.

[0077] Please see Figure 5 In one specific embodiment, the first clamping arm 313 includes: a first connecting rod 3131, a second connecting rod 3132, a third connecting rod 3133, a fourth connecting rod 3134, a first column 3135, and a second column 3136. The first connecting rod 3131 is connected to the second connecting rod 3132, and the third connecting rod 3133 is connected to the fourth connecting rod 3134. The first end of the first column 3135 is connected to the first connecting rod 3131 and the second connecting rod 3132, and the second end of the first column 3135 is connected to the third connecting rod 3133 and the fourth connecting rod 3134, respectively. The first end of the second column 3136 is connected to the second connecting rod 3132, and the second end is connected to the fourth connecting rod 3134.

[0078] It should be noted that, in combination Figure 5 The first end of the first column 3135 is the upper end, and the second end is the lower end. The first end of the second column 3136 is the upper end, and the second end is the lower end.

[0079] The first clamping arm 313 is configured as a first link 3131, a second link 3132, a third link 3133, a fourth link 3134, a first column 3135, and a second column 3136. That is, the first clamping arm 313 is composed of multiple links and columns, which can save materials and reduce manufacturing costs.

[0080] Please see Figure 6In one specific embodiment, the second clamping arm 314 includes: a fifth link 3141, a sixth link 3142, a seventh link 3143, an eighth link 3144, a third column 3145, and a fourth column 3146. The fifth link 3141 is connected to the sixth link 3142, the seventh link 3143 is connected to the eighth link 3144, the first end of the third column 3145 is connected to the fifth link 3141 and the sixth link 3142 respectively, and the second end of the fourth column 3146 is connected to the seventh link 3143 and the eighth link 3144 respectively.

[0081] It should be noted that, in combination Figure 6 The first end of the third column 3145 is the upper end, and the second end is the lower end. The first end of the fourth column 3146 is the upper end, and the second end is the lower end.

[0082] The second clamping arm 314 is configured as a fifth link 3141, a sixth link 3142, a seventh link 3143, an eighth link 3144, a third column 3145, and a fourth column 3146. That is, the second clamping arm 314 is composed of multiple links and columns, which can save materials and reduce manufacturing costs.

[0083] In one specific embodiment, one end of the first transmission rod 315 is hinged to the first column 3135, and the other end is hinged to the third column 3145.

[0084] 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 invention.
