Description

Technical Field

[0001] This application relates to the technical field of graphitization furnace rectifier units, and in particular to an electrode clamping mechanism and a power supply vehicle. Background Technology

[0002] A power transmission car is a rectifier unit used to supply power to a graphitization furnace. The power transmission car is equipped with an electrode clamping mechanism and a busbar clamping mechanism that are electrically connected to each other. During power transmission, the electrode clamping mechanism clamps the conductive electrodes of the graphitization furnace, and the busbar clamping mechanism clamps the power supply busbar to support the production of the graphitization furnace.

[0003] In existing technology, the energized part includes an electrode clamping mechanism and a column. The electrode clamping mechanism is fixedly mounted on a support extending from one side of the column (see CN202310255343.1). In scenarios where a power supply vehicle supplies power to a graphitization furnace, the distance between two adjacent conductive electrodes of the graphitization furnace is relatively fixed. When workers find that the height of the electrode clamp is not suitable for the conductive electrodes of the graphitization furnace, a small steel plate of 1-2 mm is usually added between the support and the electrode clamp as a shim to fine-tune the height of the electrode clamping mechanism. However, each power supply vehicle has several electrode clamps, and each electrode clamp requires a shim to adjust its height, which is too cumbersome and inefficient.

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

[0005] (a) Technical problems to be solved

[0006] Based on this, the present invention provides an electrode clamping mechanism and a power supply vehicle, which has a simple structure and strong practicality.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model proposes an electrode clamping mechanism, which includes: a conductive frame, on which a positioning post is fixedly disposed; and a column, which is disposed on the conductive frame and on which a plurality of electrode clamps are disposed, the electrode clamps being sleeved on the positioning post and pivoting relative to the positioning post.

[0009] Furthermore, the electrode clamp also includes: a clamping arm, a driving cylinder, and an electrode clamping plate, one end of the clamping arm being pivotally connected to the driving cylinder, and the other end of the clamping arm being pivotally connected to the electrode clamping plate.

[0010] Furthermore, two bushings are fixedly disposed on the positioning post along its axial direction, and the two bushings are engaged with the clamping arm from the upper and lower sides.

[0011] Furthermore, the clamping arm has a through cavity extending from left to right, and the positioning post is engaged within the cavity of the clamping arm.

[0012] Furthermore, the electrode clamp also includes a conductive connector, one end of which is fixedly connected to the column, and the other end of which is laid on the inner side of the electrode clamp plate.

[0013] Furthermore, the electrode clamp includes a plate body and an insulating pad disposed on the inner side of the plate body, and the conductive connector is disposed on the insulating pad.

[0014] Furthermore, the conductive connector includes: a fixing plate, a flexible copper strip, and a contact copper busbar, wherein the fixing plate is connected to the flexible copper strip, and the flexible copper strip is connected to the contact copper busbar.

[0015] Furthermore, the conductive frame includes: a conductive base, a conductive connecting beam, and a conductive top seat, wherein the conductive connecting beam is disposed on the conductive base, and the conductive top seat is disposed on the conductive connecting beam.

[0016] Furthermore, the conductive base is hollow and has several parallel mounting posts inside. The electrode is clamped on the mounting posts, and the conductive top seat extends downward to provide a mounting plate. The column is fixedly mounted on the mounting plate.

[0017] This utility model also provides a power transmission vehicle, which includes: a vehicle body, a gantry, a lifting mechanism, a translation mechanism, and the electrode clamping mechanism. The gantry is movably disposed on the vehicle body and configured to move back and forth under the drive of the translation mechanism. The electrode clamping mechanism is suspended below the gantry and rises and falls under the drive of the lifting mechanism.

[0018] (III) Beneficial Effects

[0019] Compared with existing technologies, the electrode clamping mechanism provided by this invention involves mounting the electrode clamp on a positioning post, with the clamp pivoting relative to the post. In scenarios where a power supply vehicle supplies power to a graphitization furnace, the distance between two adjacent conductive electrodes on either side of the furnace is relatively fixed. A lifting mechanism raises and lowers the conductive frame, thereby adjusting the height of the electrode clamp fixed on the positioning post. This means that the operator can adjust the electrode clamp in one operation to adapt to the graphitization furnace, making the operation simple, reliable, and highly practical. Furthermore, it eliminates the need for a small steel plate as a height adjustment accessory, resulting in a simple structure and low operating costs. Attached Figure Description

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. 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.

[0035] Please see Figures 1 to 6 In one embodiment, to address the problem of the complex structure of the electrode clamping mechanism 100, this application proposes an electrode clamping mechanism 100, which includes: a conductive frame 10 and a column 20. The column 20 is disposed on the conductive frame 10, and a positioning column 11 is fixedly disposed on the conductive frame 10. A plurality of electrode clamps 30 are disposed on the column 20, and each electrode clamp 30 includes a clamping arm 31, which is sleeved on the positioning column 11 and can pivot relative to the positioning column 11. The electrode clamping mechanism 100 includes three mutually spaced columns 32, and three electrode clamps 30 are distributed along the length of each column 32 to form a 3*3 square array, corresponding to the distribution of conductive electrodes on the graphitization furnace. Compared with the prior art, the electrode clamping mechanism 100 provided by this invention, by sleeved on the positioning column 11, allows the electrode clamps 30 to pivot relative to the positioning column 11. In scenarios where a power supply vehicle supplies electricity to a graphitization furnace, the distance between two adjacent conductive electrodes of the furnace is relatively fixed. The lifting mechanism 43 drives the conductive frame 10 to rise and fall, thereby adjusting the height of the electrode clamps 30 fixed on the positioning posts 11 of the conductive frame 10. This means that the operator can adjust the electrode clamps 30 to fit the graphitization furnace in one operation, making the operation simple, reliable, and highly practical. Furthermore, there is no need to equip them with small steel plates as height adjustment accessories, resulting in a simple structure and low operating costs.

[0036] Please see Figures 3 to 5 In one embodiment, two bushings 311 are fixedly provided on the positioning post 11 along its axial direction, and the two bushings 311 are respectively engaged with the clamping arm 31 from the upper and lower sides of the clamping arm 31.

[0037] Furthermore, two spaced bushings 311 are fixedly installed on the positioning post 11. The two bushings 311 are respectively engaged with the clamping arm 31 from the upper and lower sides of the clamping arm 31. The cross-sectional area of ​​the bushings 311 is configured to be slightly larger than that of the cavity 312 to achieve an interference fit between the bushings 311 and the positioning post 11.

[0038] By setting a positioning post 11 and having the positioning post 11 locked onto the clamping arm 31 by the bushing 311, the load brought by the external force in the vertical direction can be overcome, and the clamping arm 31 can be ensured to pivot around the positioning post 11.

[0039] Please see Figures 3 to 5 In one embodiment, the clamping arm 31 has a cavity 312 that extends through the left and right sides, and the positioning post 11 is engaged in the cavity 312 of the clamping arm 31.

[0040] A cavity 312 communicating with the bushing 311 is opened through the side of the clamping arm 31. A coupling (not shown) is provided on the positioning post 11. The coupling is located in the cavity 312, thereby fixing the clamping arm 31 to the positioning post 11.

[0041] Specifically, the coupling can be a centrally perforated disc, which is fixedly mounted on the positioning post 11.

[0042] Please see Figures 3 to 5 In one embodiment, the electrode clamp 30 further includes a drive cylinder 32 and an electrode clamping plate 33, one end of the clamping arm 31 is pivotally connected to the drive cylinder 32, and the other end of the clamping arm 31 is pivotally connected to the electrode clamping plate 33.

[0043] The drive cylinder 32 provides power for the deflection of the clamping arm 31, and controls the electrode clamp 30 to be in a clamping or releasing state through external hydraulic pressure. When the electrode clamp 30 is in the clamping state, the drive cylinder 32 drives the clamping arm 31 to move closer to each other, causing the two electrode clamping plates 33 to move closer to each other, so as to stably clamp the conductive electrode; when the electrode clamp 30 is in the releasing state, the drive cylinder 32 drives the clamping arm 31 to move away from each other, so as to control the two electrode clamping plates 33 to be set further apart.

[0044] The clamping arm 31 has a cavity 312, and the positioning post 11 passes through the cavity 312 of the clamping arm 31. The cavity 312 can be set in the middle position or near the electrode clamping plate 33, so that the connection between the positioning post 11 and the clamping arm 31 can serve as a support point, which can ensure that the entire electrode clamp 30 can switch stably and reliably between the clamping state and the release state.

[0045] Please see Figures 3 to 5 In one embodiment, the electrode clamp 33 includes a plate body 331 and an insulating pad 332 disposed inside the plate body 331; the insulating pad 332 serves as insulation and can change the power transmission path of the power transmission vehicle 40 to improve power transmission efficiency.

[0046] In addition, the back side of the plate 331 is provided with reinforcing ribs, which are arranged horizontally and vertically in a grid pattern, which can increase the mechanical strength of the plate 331 itself and improve the service life of the electrode clamp 33.

[0047] Please see Figures 3 to 5 In one embodiment, the electrode clamp 30 further includes a conductive connector 34, one end of which is fixedly connected to the column 20, and the other end of which is laid on the inner side of the electrode clamp plate 33. The conductive connector 34 includes a fixing plate 341, a soft copper strip 342, and a contact copper busbar 343. The fixing plate 341 is connected to the soft copper strip 342, and the soft copper strip 342 is connected to the contact copper busbar 343.

[0048] Specifically, the fixing plate 341 has through holes (not shown) for fasteners (not shown) to pass through and fix to the column 20. The contact copper busbar 343 is disposed on the insulating pad 332 of the electrode clamp 33, i.e., on the side that contacts the conductive electrode of the graphitization furnace. Both the fixing plate 341 and the contact copper busbar 343 are made of rigid materials to ensure a stable connection between the electrode clamp 30 and the conductive electrode of the graphitization furnace; while the copper strip 342 is a flexible material that can adapt to the thermal expansion and contraction of the conductive electrode, ensuring that the fixing plate 341 and the conductive electrode of the graphitization furnace remain in close contact, thereby improving the working stability of the electrode clamp 30.

[0049] Please see Figures 1 to 2 In one embodiment, the conductive frame 10 includes: a conductive base 12, a conductive connecting beam 13, and a conductive top seat 14. The conductive connecting beam 13 is disposed on the conductive base 12, and the conductive top seat 14 is disposed on the conductive connecting beam 13. The conductive top seat 14 extends downward and is provided with a plurality of sets of mounting plates 141 arranged from left to right. A set of mounting plates 141 is fixedly disposed on both sides of the column 20 to increase the contact area between the conductive connecting beam 13 and the column 20, thereby improving the stability of the connection between the two and reducing the contact resistance to avoid overheating.

[0050] Please see Figures 1 to 2 In one embodiment, the electrode clamping mechanism 100 further includes a busbar clamp (not shown). The conductive base 12 is a hollow frame, and the conductive base 12 has several sets of mounting posts 121 arranged from left to right. One busbar clamp is pivotally connected to one set of mounting posts 121. That is, the busbar clamp can rotate about the mounting posts 121 as an axis to adaptively deflect when the busbar clamp is inserted downwards, thereby improving the stability of the connection between the busbar clamp and the power supply busbar (not shown).

[0051] Please see Figure 6 In one embodiment, this application also provides a power transmission vehicle 40, which includes: a vehicle body 41, a gantry 42, an electrode clamping mechanism 100, a lifting mechanism 43, and a translation mechanism 44. The gantry 42 is movably mounted on the vehicle body 41 and configured to move back and forth under the drive of the translation mechanism 44. The lifting mechanism 43 is fixedly mounted on the gantry 42. The electrode clamping mechanism 100 is connected to the lifting mechanism 43 and rises and falls under the drive of the lifting mechanism 43.

[0052] Specifically, the power transmission vehicle 40 has a power-on state and an idle state, and can switch between the two states. When switching to the power-on state, the translation mechanism 44 drives the gantry 42 to move forward, and the lifting mechanism 43 drives the electrode clamping mechanism 100 to descend until the electrode clamping mechanism 100 is connected to the conductive electrode of the graphitization furnace and the power transmission busbar, respectively. When switching to the idle state, the translation mechanism 44 drives the gantry 42 to move backward, and the lifting mechanism 43 drives the electrode clamping mechanism 100 to rise until the electrode clamping mechanism 100 is separated from the conductive electrode of the graphitization furnace and the power transmission busbar, respectively.

[0053] Among them, the forward movement of the gantry 42 is the movement of the trolley 40 closer to the graphitization furnace, and the backward movement of the gantry 42 is the movement of the trolley 40 away from the conductive electrode.

[0054] In summary, compared with the prior art, the electrode clamping mechanism 100 provided by this utility model, by sleeved electrode clamp 30 on positioning post 11, allows electrode clamp 30 to pivot relative to positioning post 11. In scenarios where a power supply vehicle supplies power to a graphitization furnace, the distance between two adjacent conductive electrodes of the graphitization furnace is relatively fixed. By using lifting mechanism 43 to drive the lifting of conductive frame 10, the height of electrode clamp 30 fixed on positioning post 11 of conductive frame 10 can be adjusted as a whole. In other words, the operator can complete the adjustment of electrode clamp 30 in one operation to adapt to the graphitization furnace. This makes the operation simple, reliable, and highly practical. Furthermore, it eliminates the need for a small steel plate as a height adjustment accessory, resulting in a simple structure and low operating cost.
