Description

Technical Field

[0001] This utility model relates to the technical field of mobile power transmission equipment for graphitization furnaces, and in particular to a power transfer clamping device and a power transmission vehicle. Background Technology

[0002] In the field of carbon material graphitization processing, the Atchison graphitization furnace is a key piece of equipment for converting carbon materials into artificial graphite. Its furnace body is typically a cuboid structure, with conductive electrodes at both ends of the furnace, one at the furnace head and the other at the furnace tail. An external power supply powers these electrodes, enabling the carbon materials inside the furnace to complete the graphitization reaction at a high temperature.

[0003] As a supporting power supply device for the Atchison graphitization furnace, the energizer car undertakes the core function of transmitting power to the furnace body. During the power transmission process, the energizer car needs to achieve power transmission through two key mechanisms: one is the busbar clamping mechanism, used to clamp the external power supply busbar to introduce current; the other is the electrode clamping mechanism, used to clamp the conductive electrodes at both ends of the graphitization furnace to guide current into the furnace body. Through the electrical connection between the busbar clamping mechanism and the electrode clamping mechanism, a complete power supply circuit is formed, ensuring that the graphitization furnace receives a stable current.

[0004] Typically, the power transmission vehicle is also equipped with a power transfer clamping device as an intermediate conductive component to achieve electrical connection between the busbar clamping mechanism and the electrode clamping mechanism. The power transfer clamping device mainly consists of clamps, and multiple clamps are usually provided to improve power supply reliability (such as enabling multi-path parallel power supply or redundancy backup). However, the clamps need to cooperate with the busbar clamping mechanism and the electrode clamping mechanism through their own opening and closing actions. Due to the limited space in the power transmission vehicle, the installation positions of multiple clamps are relatively compact. During the opening and closing process, the moving parts of adjacent clamps are prone to collision or mutual obstruction, causing interference. This interference not only leads to clamping action jamming and poor power supply contact, but may also cause damage to the clamps or electrodes due to mechanical collisions, seriously affecting the stable operation of the graphitization furnace and production safety.

[0005] In view of this, the present invention provides a new solution to the above problems. Utility Model Content

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Typically, a power transfer clamping device is installed on the power transmission car as an intermediate conductive component to achieve electrical connection between the busbar clamping mechanism and the electrode clamping mechanism. The power transfer clamping device mainly consists of clamps. To improve power supply reliability (such as enabling multi-path parallel power supply or redundancy backup), multiple clamps are usually arranged side-by-side in the horizontal direction on the power transmission car. However, the clamps need to cooperate with the busbar clamping mechanism and the electrode clamping mechanism through their own opening and closing actions. Due to the limited space on the power transmission car, the installation positions of multiple clamps are relatively compact. During the opening and closing process, the moving parts of adjacent clamps are prone to collision or mutual obstruction, causing interference. This interference not only leads to clamping action jamming and poor power supply contact, but may also cause damage to the clamps or electrodes due to mechanical collisions, seriously affecting the stable operation of the graphitization furnace and production safety.

[0043] To address the problem of interference between multiple clamps on the power transmission vehicle during opening and closing, this invention provides a novel power transfer clamping device and power transmission vehicle. The maximum opening angle of the clamps can be limited by a limiting component, which can prevent interference between adjacent clamps during opening and closing and ensure the normal operation of each clamp.

[0044] Example: A power transfer clamping device 5 and a power transmission vehicle, such as Figure 1-3 As shown, the power transmission vehicle includes a vehicle body 1, an electrode clamping mechanism 2, a busbar clamping mechanism 3, a conductive component 4, and a power transfer clamping device 5. The electrode clamping mechanism 2, busbar clamping mechanism 3, conductive component 4, and power transfer clamping device 5 are all mounted on the vehicle body 1. The busbar clamping mechanism 3 is used to clamp the external power supply busbar to introduce current. The conductive component 4 is connected to the busbar clamping mechanism 3. The power transfer clamping device 5 is used to clamp the conductive component 4 so that current flows through the busbar clamping mechanism 3, conductive component 4, power transfer clamping device 5, and electrode clamping mechanism 2 into the furnace body. The electrode clamping mechanism 2 is used to clamp the conductive electrodes at both ends of the graphitization furnace to introduce current into the furnace body.

[0045] In this embodiment, the vehicle body 1, the electrode clamping mechanism 2, and the busbar clamping mechanism 3 are all existing technologies, so their specific structures and working principles will not be described in detail here.

[0046] like Figure 1-6As shown, the power transfer clamping device 5 includes a busbar 51 and multiple power transfer clamping mechanisms 52. The busbar 51 is mounted on the body 1 of the power transmission vehicle and connected to the electrode clamping mechanism 2. Each power transfer clamping mechanism 52 includes a conductor 521, a bracket 522, a clamp 523, a drive assembly 524, and a limiting assembly 525. The conductor 521 is used to connect to the electrode clamping mechanism 2 via the busbar 51. Specifically, the conductor 521 is fixed below the busbar 51 as a conductive branch. The bracket 522 is mounted on the busbar 51. It can be understood that the bracket 522 can be directly fixed to the busbar 51 through direct contact or indirectly. In this embodiment, the bracket 522 and the busbar 51 are indirectly fixed. Specifically, a support frame is provided around the busbar 51. The support frame can be fixed by bolts, welding, or an external frame, which is known technology and will not be described in detail here. The bracket 522 is fixed to the support frame. The clamp 523 is mounted on the bracket 522 and connected to the conductor 521. The clamp 523 is used to clamp the conductive component 4 connected to the busbar clamping mechanism 3, so that the electrode clamping mechanism 2 is electrically connected to the busbar clamping mechanism 3. The driving component 524 is used to drive the clamp 523 to open or close, and the limiting component 525 is used to limit the maximum opening angle of the clamp 523.

[0047] In the above technical solution, the present invention precisely limits the maximum opening angle of the clamp 523 by limiting component 525. Even in a compact layout, the moving parts of adjacent mechanisms will not collide or obstruct each other, effectively solving the interference problem in the opening and closing process, ensuring the normal operation of each mechanism, and reducing equipment damage and power outages caused by interference.

[0048] like Figure 1-6 As shown, the bracket 522 includes a first support arm 5221, a second support arm 5222, and a connecting rod 5223. The first support arm 5221 and the second support arm 5222 are connected by the connecting rod 5223. The first support arm 5221 and the second support arm 5222 are suspended and fixed on the support frame of the busbar 51. The clamp 523 is suspended above the busbar clamping mechanism 3 through the first support arm 5221 and the second support arm 5222.

[0049] In the above technical solution, the clamp 523 is suspended above the busbar clamping mechanism 3 by the bracket 522 and is not directly connected to the busbar clamping mechanism 3. This avoids the problem of mutual influence and interference between the two during frequent opening and closing operations, and ensures the normal operation of each mechanism.

[0050] like Figure 1-6As shown, the conductive component 4 includes a conductive plate 41 and a conductive base 42 connected to the conductive plate 41. The conductive plate 41 is connected to the busbar clamping mechanism 3. The clamp 523 is used to clamp the conductive base 42 so that the current on the conductive base 42 is introduced into the conductor 521 and the busbar 51 through the clamp 523.

[0051] like Figure 1-6 As shown, the clamp 523 includes a first clamping arm 5231, a second clamping arm 5232, a first clamping plate 5233, a second clamping plate 5234, a connecting plate 5235, and a conductive clamping plate 5236. The first clamping plate 5233 and the second clamping plate 5234 are arranged opposite to each other and are used for clamping. One end of the connecting plate 5235 is rotatably connected to the middle section of the first clamping arm 5231, and the other end is rotatably connected to the middle section of the second clamping arm 5232. The connecting plate 5235 is fixed to the lower ends of the first support arm 5221 and the second support arm 5222. The driving assembly 524 is located between the first clamping arm 5231 and the second clamping arm 5232. The upper end of the first clamping arm 5231 is rotatably connected to the driving assembly 524, and the lower end is connected to the first clamping plate 5233. The upper end of the second clamping arm 5232 is rotatably connected to the driving assembly 524, and the lower end is connected to the second clamping plate 5234. Two conductive clamps 5236 are provided, which are fixed inside the first clamp 5233 and the second clamp 5234 respectively and are both connected to the conductor 521. The two conductive clamps 5236 are arranged symmetrically. The conductor 521 is located between the two conductive clamps 5236, and the two conductive clamps 5236 are always connected to the conductor 521.

[0052] To improve the connection stability between the conductive clamp 5236 and the conductor 521 and maintain the safety of current conduction, it is further preferred that the conductive clamp 5236 is a flexible aluminum plate with its upper side connected to the conductor 521. Two conductive clamps 5236 are provided, fixed symmetrically to the inner sides of the first clamp 5233 and the second clamp 5234 respectively. When the trolley is in operation, the first clamp 5233 and the second clamp 5234 will move the lower ends of the two conductive clamps 5236 closer together, so that the lower ends of the conductive clamps 5236 contact the conductive base 42, achieving electrical connection.

[0053] In the above technical solution, the conductivity of the power transfer clamping device 5 is achieved through the conductive clamp 5236. The two flexible aluminum plates (conductive clamps 5236) fixed inside the first clamp 5233 and the second clamp 5234 respectively will move closer together with the first clamp 5233 and the second clamp 5234 and fit tightly against the conductive base 42 when the clamp 523 is closed, thus achieving stable power transmission.

[0054] like Figure 1 , 2As shown in Figures 6 and 7, in this embodiment, the power transfer clamping device 5 includes four power transfer clamping mechanisms 52 and a busbar 51. The four power transfer clamping mechanisms 52 are located in pairs at both ends of the vehicle body 1. The four power transfer clamping mechanisms 52 are connected to the electrode clamping mechanism 2 after being combined through the busbar 51. The busbar clamping mechanism 3 is located below the conductive component 4, and the power transfer clamping device 5 is located above the busbar clamping mechanism 3.

[0055] like Figure 4-6 As shown, preferably, the drive assembly 524 is a cylinder or a hydraulic cylinder.

[0056] Specifically, in this embodiment, the drive assembly 524 is a hydraulic cylinder, and the end of the cylinder body is hinged to the first clamping arm 5231, and the end of the cylinder shaft is hinged to the second clamping arm 5232.

[0057] Further preferably, to improve the clamping stability of the clamp 523, two first clamping arms 5231, a second clamping arm 5232, a drive assembly 524, and a connecting plate 5235 can be respectively provided on opposite sides of the first clamping plate 5233 and the second clamping plate 5234. One end of the connecting rod 5223 passes through one of the connecting plates 5235 and is fixed to the lower end of the first support arm 5221, and the other end passes through the other connecting plate 5235 and is fixed to the lower end of the second support arm 5222, so that the connecting rod 5223 provides good support for the connecting plate 5235. This double-sided symmetrical structural design makes the clamping force distribution more uniform, avoiding clamping instability or component damage caused by unilateral force.

[0058] In the above technical solution, the first clamping arm 5231 and the second clamping arm 5232 are symmetrically distributed, and their middle sections are rotatably connected to the connecting plate 5235 via pins, forming a lever-type linkage structure. The connecting plate 5235 is fixed on the bracket 522 and serves as the support base of the clamp 523.

[0059] One end of the first clamping arm 5231 is connected to the first clamping plate 5233, and the other end is connected to the cylinder end of the drive assembly 524 via a hinge shaft. One end of the second clamping arm 5232 is connected to the second clamping plate 5234, and the other end is also hinged to the cylinder shaft end of the drive assembly 524 via a hinge shaft. Taking the hydraulic cylinder as the driving source as an example, when the cylinder shaft of the hydraulic cylinder extends, its end pushes the ends of the first clamping arm 5231 and the second clamping arm 5232 outward through the hinge shaft. Since the middle sections of the first clamping arm 5231 and the second clamping arm 5232 are rotatably connected to the connecting plate 5235 fixed on the bracket 522 via a pin, forming a lever fulcrum, when the end is subjected to force, the front ends of the two clamping arms (the end connected to the clamping plate) will rotate inward around the fulcrum, causing the first clamping plate 5233 and the second clamping plate 5234 to move closer to each other, completing the closing clamping action. When the cylinder shaft retracts, it pulls the ends of the first clamping arm 5231 and the second clamping arm 5232 inward. Similarly, using the lever principle, the front ends of the two clamping arms rotate outward around the fulcrum, causing the first clamping plate 5233 and the second clamping plate 5234 to move away from each other, thus achieving the opening action. Throughout the process, the driving force of the cylinder is amplified through the lever structure, ensuring that the first clamping plate 5233 and the second clamping plate 5234 can provide sufficient clamping force. At the same time, the degree of opening and closing of the clamp 523 can be initially adjusted by controlling the extension and retraction of the cylinder.

[0060] Preferably, the upper ends of the first support arm 5221 and the second support arm 5222 are detachably connected to the busbar 51.

[0061] Specifically, the upper ends of the first support arm 5221 and the second support arm 5222 are both bolted to the busbar 51. This detachable connection method facilitates the installation, disassembly, maintenance, and replacement of the bracket 522. When the bracket 522 or the clamp 523 malfunctions, it can be easily replaced, reducing maintenance costs.

[0062] like Figure 4-8 As shown, the limiting components 525 are symmetrically arranged on opposite sides of the first support arm 5221 and the second support arm 5222. The limiting components 525 include a limiting block 5251, a limiting mating part 5252, and an adjusting member 5253. The limiting block 5251 is disposed on the first support arm 5221 and the second support arm 5222, and the limiting mating part 5252 is disposed on the clamp 523. When the clamp 523 is opened to its maximum angle, the limiting mating part 5252 abuts against the limiting block 5251.

[0063] Preferably, the limiting block 5251 includes a limiting plate 52511 and two fixing plates 52512. The limiting plate 52511 is fixed to the opposite sides of the first support arm 5221 and the second support arm 5222 by the two fixing plates 52512. The limiting plate 52511 is located on the side of the fixing plate 52512 near the limiting mating part 5252. The limiting mating part 5252 is located between the connecting plate 5235 and the drive assembly 524 and is fixed on the first clamping arm 5231 and the second clamping arm 5232 of the clamp 523. The limiting mating part 5252 includes a mounting plate 52521 and a reinforcing plate 52522. The mounting plate 52521 is fixed on the first clamping arm 5231 and the second clamping arm 5232 of the clamp 523.

[0064] More preferably, the adjusting member 5253 is used to adjust the limiting degree of the limiting component 525 to change the maximum opening angle of the clamp 523. The adjusting member 5253 is detachably mounted on the limiting block 5251 and / or the limiting mating part 5252.

[0065] Specifically, the adjusting element 5253 is a bolt, and the bolt thread is installed on the limiting block 5251 and / or the limiting mating part 5252.

[0066] In this embodiment, the bolt thread is installed on the mounting plate 52521 of the limiting mating part 5252. In order to improve the limiting stability of the bolt, a nut can also be installed on the bolt in this embodiment, and the nut is set to contact the mounting plate 52521.

[0067] Preferably, the mounting plate 52521 has threaded holes, and bolts are installed in the threaded holes with their ends used to abut against the limiting plate 52511. Reinforcing plates 52522 are fixed to the mounting plate 52521 and the first clamping arm 5231 and the second clamping arm 5232 of the clamp 523. Two reinforcing plates 52522 are provided, symmetrically arranged on opposite sides of the threaded holes.

[0068] In the above technical solution, adjusting the maximum opening angle of the clamp 523 only requires rotating the adjusting bolt. When the bolt is screwed outward (towards the limiting plate 52511), its length extending beyond the mounting plate 52521 increases, and the opening angle of the clamp 523 decreases when it contacts the limiting plate 52511; when the bolt is screwed inward, the extension length shortens, and the maximum opening angle of the clamp 523 increases. In practical applications, the maximum opening angle of each clamp 523 can be controlled within a suitable range according to the installation spacing of adjacent electro-clamping devices 5, ensuring no interference when multiple mechanisms open simultaneously.

[0069] The limiting component 525 mechanically abuts against the clamp 523 to limit its maximum opening angle, thus preventing interference between multiple adjacent mechanisms. When the clamp 523 opens, the limiting mating part 5252 fixed on the first clamping arm 5231 and the second clamping arm 5232 moves with the clamp 523. When it opens to the preset maximum angle, the end of the adjusting bolt on the limiting mating part 5252 abuts against the limiting plate 52511 of the limiting block 5251 fixed on the bracket 522. At this point, the clamp 523 cannot open further, thus limiting the maximum opening angle. This utility model precisely limits the maximum opening angle of the clamp 523 through the limiting component 525, and combined with the flexible adjustment function of the adjusting part 5253, the opening angle of multiple clamps 523 can be controlled within a safe range according to the actual installation space of the power transmission vehicle.

[0070] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
