Description

[0001] The present invention relates to the technical field of moving power supply equipment for graphitization furnaces, and particularly to a trolley for power supply. Background Art

[0002] The Acheson graphitization furnace is a device used to convert carbon materials into artificial graphite. Its furnace body is in a cuboid shape, and conductive electrodes are provided at both ends of the furnace head and the furnace tail. The trolley for power supply completes the graphitization process by supplying power to the graphitization furnace. During the power supply process, the trolley for power supply clamps the power supply busbar through a busbar clamping mechanism, and at the same time, the electrode clamping mechanism clamps the conductive electrode, so as to realize the electrical connection between the busbar clamping mechanism and the electrode clamping mechanism and complete the power supply.

[0003] In the prior art, a water-cooled cable is fixedly connected between the busbar clamping mechanism and the electrode clamping mechanism. However, since the trolley for power supply frequently switches between the working state and the release state, the water-cooled cable needs to move along with the electrode clamping mechanism, resulting in a large mechanical stress on the water-cooled cable. After long-term use, it is prone to fatigue fracture, affecting the reliability and service life of the equipment. Summary of the Invention

Detailed implementation mode

[0037] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout.

[0039] The power supply vehicle is a movable device for supplying power to the graphitization furnace. An electrode clamping mechanism and a busbar clamping mechanism that are electrically connected to each other are provided on the power supply vehicle.

[0040] The power supply vehicle has a working state and a release state and can switch between the two states. When in the working state, the electrode clamping mechanism moves forward to clamp the conductive electrode, and at the same time the busbar clamping mechanism clamps the power supply busbar to transmit the current from the power supply busbar to the conductive electrode, so as to meet the requirements of the power supply and temperature increase process of the graphitization furnace; when in the release state, the electrode clamping mechanism releases the conductive electrode, the busbar clamping mechanism releases the power supply busbar, the electrode clamping mechanism resets to the original position, and the power supply vehicle moves in the direction of the next graphitization furnace.

[0041] In the prior art, the busbar clamping mechanism and the electrode clamping mechanism are connected by a water-cooled cable. Since the water-cooled cable needs to move with the electrode clamping mechanism for a long time, the degree of mechanical wear and tear is relatively high, and it is prone to breakage, resulting in unstable connection between the electrode clamping mechanism and the busbar clamping mechanism, and poor power transmission stability of the power transmission vehicle.

[0042] To solve the above defects existing in the water-cooled cable, please refer to Figure 1 and Figure 2 One specific embodiment of the present application provides a power transmission vehicle. Among them, a graphitization furnace is arranged on one side of the power transmission vehicle, and a power transmission busbar is arranged directly below the power transmission vehicle.

[0043] The power transmission vehicle includes: a vehicle body 1, an electrode clamping mechanism 2 and a busbar clamping mechanism 3. The electrode clamping mechanism 2 and the busbar clamping mechanism are both arranged on the vehicle body 1.

[0044] Specifically, the vehicle body 1 is provided with a sliding assembly 11 and an on-vehicle busbar 12. The on-vehicle busbar 12 is configured to be fixed on the sliding assembly 11 and can move synchronously under the drive of the sliding assembly 11.

[0045] The electrode clamping mechanism 2 is fixed on the sliding assembly 12 and is electrically connected to the busbar clamping mechanism 3 through the on-vehicle busbar 11. The busbar clamping mechanism 3 is fixedly arranged on the non-moving part of the vehicle body 1.

[0046] When the power transmission vehicle conducts power transmission, the sliding mechanism 11 drives the electrode clamping mechanism 2 to move towards the graphitization furnace until the electrode clamping mechanism 2 clamps the conductive electrode of the graphitization furnace. The on-vehicle busbar moves to a position where the busbar clamping mechanism can clamp the on-vehicle busbar 11. When the power transmission vehicle finishes power transmission, the sliding mechanism 11 drives the electrode clamping mechanism 2 to move away from the graphitization furnace until the electrode clamping mechanism 2 is separated from the graphitization furnace, and the busbar clamping mechanism 3 is separated from the on-vehicle busbar 11.

[0047] The power transmission vehicle of the present application is provided with an electrode clamping mechanism 2 and a busbar clamping mechanism 3, and the electrode clamping mechanism 2 and the busbar clamping mechanism 3 are electrically connected through the on-vehicle busbar 11. The on-vehicle busbars 11 are all rigid, so that the connection between the electrode clamping mechanism 2 and the busbar clamping mechanism 3 is stable and reliable.

[0048] In one specific embodiment, the busbar clamping mechanism 3 includes: an on-vehicle busbar clamping mechanism 31 and a main busbar clamping mechanism 32. The on-vehicle busbar clamping mechanism 31 is connected to the main busbar clamping mechanism 32.

[0049] Among them, the busbar clamping mechanism 3 has a working state and a release state. When in the working state, the on-vehicle busbar clamping mechanism 31 clamps the on-vehicle busbar 11, and power is conducted between the electrode clamping mechanism 2 and the busbar clamping mechanism 3. When in the release state, the on-vehicle busbar clamping mechanism 31 releases the on-vehicle busbar 11, and the connection between the electrode clamping mechanism 2 and the busbar clamping mechanism 3 is disconnected.

[0050] The on-vehicle busbar clamping mechanism 31 and the on-vehicle busbar 11 are designed to be clamped and connected. The connection is stable and reliable, and the two can be separated from each other quickly and completely, further enhancing the ability to cut off power quickly in case of emergency, reducing potential safety hazards, ensuring the safety of equipment operation, extending the service life of the equipment, and improving the reliability of the system.

[0051] In this embodiment, the rigid on-vehicle busbar 11 is fixed to the electrode clamping mechanism 2, and the on-vehicle busbar 11 moves with the electrode clamping mechanism 2. An on-vehicle busbar clamping mechanism 31 is provided to clamp and release the on-vehicle busbar 11. That is to say, by setting the on-vehicle busbar 11 to replace the water-cooled cable in the prior art, the mechanical loss caused by the movement of the original water-cooled cable following the electrode clamping mechanism 2 is eliminated, and the equipment replacement cost is reduced.

[0052] Please refer to Figure 2 and Figure 3 , it should be noted that: the on-vehicle busbar 11 includes a transverse aluminum bar 111 and a branch aluminum bar 112. The transverse aluminum bar 111 is connected to at least one branch aluminum bar 112 and is perpendicular to each other. The transverse aluminum bar 111 is fixed to the sliding component 12, and the busbar clamping mechanism 3 is used to clamp the branch aluminum bar 112.

[0053] Specifically, the on-vehicle busbar 11 is composed of a plurality of transverse aluminum bars 111 and branch aluminum bars 112 spliced together, reducing the difficulty in the production and transportation of the on-vehicle busbar 11.

[0054] Please refer to Figure 4 and Figure 5 , the sliding component 12 includes a column 121 and a sliding seat 122. The column 121 can slide linearly back and forth on the sliding seat 122. The electrode clamping mechanism 2 is arranged on the column 121, and the on-vehicle busbar 11 is arranged on one side of the column 121 opposite to the electrode clamping mechanism 2.

[0055] Specifically, four columns 121 are fixedly installed on the sliding seat 122. The bottom of the sliding seat 122 is sleeved with three sliding rods, so that the sliding seat 122 can move within the position set by the sliding rods. Among them, one end direction of the sliding rod is the same as the direction of the conductive electrode, and the on-vehicle busbar 11 is fixed on the column 121.

[0056] Exemplarily, when in the working state, the sliding assembly 12 reaches the closest point to the conductive electrode, and at the closest point, the electrode clamping mechanism 2 clamps the conductive electrode. When in the release state, the sliding assembly 12 reaches the farthest point from the conductive electrode, preventing the electrode clamping mechanism 2 from colliding with the conductive electrode due to too close a distance during the movement of the power supply vehicle.

[0057] Please refer to Figure 6 , in one specific embodiment, the main busbar clamping mechanism 32 includes: two clamping arms 321, two main aluminum busbar clamps 322, and a driving oil cylinder 323. The driving oil cylinder 323 is respectively connected to one end of the two clamping arms 321, and the two main aluminum busbar clamps 322 are respectively connected to the other end of the clamping arms 321. When in the working state, the driving oil cylinder 323 drives the clamping arms 321 to approach each other, so as to drive the two main aluminum busbar clamps 322 to jointly clamp the power supply busbar.

[0058] Please refer to Figure 6 and Figure 8 , the busbar clamping mechanism 3 further includes a main copper plate 33. The main copper plate 33 is respectively connected to the vehicle-mounted busbar clamping mechanism 31 and the main busbar clamping mechanism 32. The vehicle-mounted busbar clamping mechanism 31 and the main busbar clamping mechanism 32 are respectively arranged on both sides of the main copper plate 33.

[0059] Sharing the main copper plate 33, with the vehicle-mounted busbar clamping mechanism 31 located above the main copper plate 33 and the main busbar clamping mechanism 32 located below the main copper plate 33, the fact that the main busbar clamping mechanism 32 and the vehicle-mounted busbar clamping mechanism 31 share the main copper plate 33 enables the busbar clamping mechanism 3 to have good electrical conductivity during the process of transmitting current.

[0060] Please refer to Figure 1 , Figure 6 and Figure 7 , the busbar clamping mechanism 3 further includes a fixing component 34. The fixing component 34 is in the shape of a cuboid. The two ends of the fixing component 34 are fixed to the vehicle body 1, and the middle part of the fixing component 34 is fixed to the busbar clamping mechanism 3.

[0061] The fixing component 34 provides a supporting force for the busbar clamping mechanism 3 and insulates the busbar clamping mechanism 3 from the vehicle body 1.

[0062] Specifically, the fixing component 34 is composed of a mounting plate 341 and insulating plates 342. The upper and lower insulating plates 342 jointly clamp the mounting plate 341 in the middle. The insulating plate 342 at the bottom is fixed to the busbar clamping mechanism 3. The two sides of the mounting plate 341 extend outward, and mounting holes are provided at the extending parts of the mounting plate 341. Oil cylinder bases 313 are arranged side by side on both sides of the insulating plate 342 at the upper layer, and can fit with the mounting holes of the mounting plate 341. On the basis of fixing the busbar clamping mechanism 3 to the vehicle body 1, the fixing component 34 avoids the current flowing into the vehicle body 1 during the working process of the power supply vehicle through the double-layer insulating plates 342.

[0063] In one specific embodiment, two vehicle-mounted busbars 11 are provided on the sliding assembly 12. By adopting two vehicle-mounted busbars 11, the stability of the connection between the electrode clamping mechanism 2 and the busbar clamping mechanism 3 can be further improved.

[0064] The vehicle-mounted busbar clamping mechanism 31 includes: a first vehicle-mounted clamp body 311, an oil cylinder 312, and a bracket 314;

[0065] In this embodiment, the vehicle-mounted busbar clamping mechanism 31 is provided with two first vehicle-mounted clamp bodies 311, and the two first vehicle-mounted clamp bodies 311 are arranged in parallel; the two first vehicle-mounted clamp bodies 311 are respectively connected to the output shafts of the two oil cylinders 312 to drive the two first vehicle-mounted clamp bodies 311 to clamp or release the vehicle-mounted busbar 11; the two oil cylinders 312 are respectively installed on the two brackets 314.

[0066] In the vehicle-mounted busbar clamping mechanism 31 of this embodiment, the first vehicle-mounted clamp bodies 311, the oil cylinders 312, and the brackets 314 are arranged in pairs, and the vehicle-mounted busbar 11 is clamped by the two first vehicle-mounted clamp bodies 311, and the structure is simple and reliable.

[0067] In one specific embodiment, the vehicle-mounted busbar clamping mechanism 31 further includes: an oil cylinder base 313 and a two-way oil cylinder 315. The oil cylinder base 313 is arranged between the two first vehicle-mounted clamp bodies 311, the two-way oil cylinder 315 is fixedly installed on the oil cylinder base 313, and the two output shafts of the two-way oil cylinder 315 are both connected with second vehicle-mounted clamp bodies 316.

[0068] The second vehicle-mounted clamp bodies 316 cooperate with the first vehicle-mounted clamp bodies 311 to clamp the two vehicle-mounted busbars 11.

[0069] In the busbar clamping mechanism 3 with a complex structure itself, the position of one oil cylinder 312 can be omitted for the above-mentioned oil cylinder 312, simplifying the mechanical mechanism and saving production costs.

[0070] Furthermore, the first vehicle-mounted clamp body 311 is provided with a pressing plate 3111, a clamping portion 3112, and a bending portion 3113; the back of the pressing plate 3111 of the first vehicle-mounted clamp body 311 is connected to the oil cylinder 312, the front of the pressing plate 3111 is fixed to the clamping portion 3112, and the lower end of the clamping portion 3112 is connected to the bending portion 3113. Here, the clamping portion 3112 and the bending portion 3113, it is worth mentioning that the bending portion 3113 will move together and deform during the clamping and releasing processes of the first vehicle-mounted clamp body 311.

[0071] Please refer to Figure 6 and Figure 9, the oil cylinder base 313 includes: a bottom plate 3131 and a support plate 3132. The bottom plate 3131 of the oil cylinder base 313 is placed on the fixing component 34. A number of support plates 3132 form a rectangular cuboid structure of a sealing plate, and an arc-shaped groove is left at the top for placing the double-headed oil cylinder 315. This can prevent displacement during the pushing process of the double-headed oil cylinder 315 and support the double-headed oil cylinder 315 at the same time.

[0072] Please refer to Figure 6 and Figure 10 , it should be noted that the double-acting oil cylinder 315 includes: a cylinder block 3151 and a push rod 3152. The push rod 3152 is located at both ends of the cylinder block 3151.

[0073] Please refer to Figure 6 and Figure 11 , since the bracket in the prior art has problems such as poor mechanical strength and short service life; therefore, in this embodiment, the structure of the bracket 314 is newly designed.

[0074] In this embodiment, the bracket 314 includes: side plates 3141, rib plates 3142 and connecting plates 3143; circular holes are provided on the side plates 3141 for fixing the oil cylinder 312. Three rib plates 3142 are fixed on the back of the side plates 3141. The rib plates 3142 are arranged side by side at intervals. One end of the rib plate 3142 is connected to the side plate 3141, and the other end is fixed to the connecting plate 3143. There are two connecting plates 3143 in the bracket 314. The connecting plate 3134 is arranged parallel to the side plate 3141, and the two connecting plates 3141 are also arranged parallel to each other. The connecting plate 3141 is located in the lower half of the side plate 3141. The mechanical strength of the bracket 314 is greatly enhanced by the connection between several plates, and the service life is improved.

[0075] The bus bar clamping mechanism 3 of this embodiment adopts the bracket 314. The bracket 314 supports both the vehicle-mounted bus bar clamping mechanism 31 and the main bus bar clamping mechanism 32 at the same time, with a simple and compact structure and high integration.

[0076] In summary, please refer to Figures 1 to 9 , according to the above description of the trolley, it should be noted that: the trolley has a working state and a release state.

[0077] When entering the working state, the motor drives the sliding seat 122 to move towards the conductive electrode. The vehicle-mounted busbar 11 and the electrode clamping mechanism 2 move towards the conductive electrode along with the sliding assembly 12. When the electrode clamping mechanism 2 moves to a pre-set position, the vehicle-mounted busbar 11 is exactly at the center of the first vehicle-mounted clamp body 311 of the vehicle-mounted busbar clamping mechanism 31. Subsequently, the electrode clamping mechanism 2, the vehicle-mounted busbar clamping mechanism 31, and the main busbar clamping mechanism 32 act simultaneously. The electrode clamping mechanism 2 clamps the conductive electrode, the vehicle-mounted busbar clamping mechanism 31 clamps the vehicle-mounted busbar 11, and the main busbar clamping mechanism 32 clamps the power supply busbar. Then, power is supplied by the power supply busbar. The current is transmitted from the busbar clamping mechanism 3 to the vehicle-mounted busbar 11, then from the vehicle-mounted busbar 11 to the electrode clamping mechanism 2, and finally the power supply to the conductive electrode is completed.

[0078] When about to enter the release state, the electrode clamping mechanism 2, the vehicle-mounted busbar clamping mechanism 31, and the main busbar clamping mechanism 32 act simultaneously. The electrode clamping mechanism 2 releases the conductive electrode, the vehicle-mounted busbar clamping mechanism 31 releases the vehicle-mounted busbar 11, and the main busbar clamping mechanism 32 releases the power supply busbar. The current transmission is disconnected. The motor drives the sliding seat 122 to move in the opposite direction of the conductive electrode. The vehicle-mounted busbar 11 and the electrode clamping mechanism 2 move in the opposite direction of the conductive electrode along with the sliding assembly 12. When the electrode clamping mechanism 2 moves to a pre-set position, it stops, and the trolley starts to move to the next graphitization furnace.

[0079] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
