Description

Technical Field

[0001] This invention relates to the field of graphite processing, specifically to a large-scale graphite product conveying system with a flipping function. Background Technology

[0002] Graphite electrodes are high-temperature resistant graphite conductive materials made from petroleum coke and pitch coke as aggregates and coal tar pitch as binder through processes such as raw material calcination, crushing and grinding, batching, mixing, molding, baking, impregnation, graphitization and machining. Graphite electrodes are stored in a horizontal position, but need to be changed from a horizontal to a vertical position when the electrode is in use.

[0003] Existing patent CN109399149B discloses a graphite electrode flipping device, including a base. A mounting plate is provided above the base. Two support plates are fixedly mounted on the top of the mounting plate. A rotating plate is rotatably mounted on the side of the two support plates that are close to each other. The rotating plate is located above the mounting plate. Two sliding holes are provided on the rotating plate. Sliding plates are slidably mounted in each of the two sliding holes. Mounting blocks are fixedly mounted on the side of the two sliding plates that are close to each other. Both mounting blocks are located above the rotating plate. Sliding sliders are slidably mounted on the side of the two mounting blocks that are close to each other.

[0004] This technical solution facilitates the clamping and fixing of the graphite electrode during flipping, increasing its stability. It also provides a buffering effect during clamping, preventing damage from sudden excessive clamping force, and a shock-absorbing effect during flipping, reducing vibration-induced damage and thus protecting the graphite electrode. However, since the fixing components for the graphite electrode are integrated with the flipping device, the graphite electrode needs to be hoisted into the clamping device, making flipping inconvenient. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a large-scale graphite product conveying system with a flipping function, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a large-size graphite product conveying system with a flipping function, comprising frames for fixing graphite parts from both sides, a transport platform for transfer, and a flipping platform for flipping. Telescopic rods are fixedly installed inside the frames, and fixed semi-rings for contacting the graphite parts are fixedly installed at the free ends of the telescopic rods. Frames on the same side are fixedly connected by connecting plates on the sides. Two symmetrical frames are connected by upper limiting sleeves. Connecting frames are provided between adjacent frames. Multiple connecting frames are fixedly connected above by lifting plates. Connecting frames, limiting sleeves, and frames are connected by limiting shafts. Rotating shafts are fixedly installed on both sides of the middle of the lifting plate. A guide rail is fixedly installed on the side of the connecting plates that are far apart from each other. A guide rail sleeve is fitted onto the outer surface of the guide rail. A telescopic sleeve is fixedly installed at the bottom end of the guide rail sleeve. The bottom ends of the telescopic sleeves on the same side are fixedly connected by a fixing plate. Telescopic brackets are fixedly installed on both sides above the transport platform. A guide rail ring is fixedly installed at the free end of the telescopic bracket. When the telescopic bracket is retracted, the telescopic sleeve is fully raised, and the guide rail ring is flush with the cross section of the guide rail sleeve. A bearing bracket is fixedly installed in the middle of the upper part of the tilting platform. A receiving groove for accommodating the rotation of the rotating shaft is opened on the side of the bearing bracket near the transport platform. Support frames are inserted into the front and rear ends of both sides of the tilting platform. The upper plane of the support frame is flush with the inner bottom wall of the guide rail ring when the telescopic bracket is fully raised.

[0007] Preferably, the cross-sectional shape of the frame is U-shaped, and a reinforcing plate is fixedly installed on the side of the frame at the front and rear ends that are far apart from each other. The reinforcing plate is used to fix the vertical end and the horizontal end of the frame.

[0008] Preferably, a plug sleeve is fixedly installed on the side of the frame located at the front and rear ends that are far apart from each other. One plug sleeve has a slot in the middle. The two plug sleeves are connected by a "T"-shaped plug plate. The plug plate is connected to the slot by a plug short rod at the slot.

[0009] Preferably, the transport platform includes a support platform, the upper surface of which is provided with a protrusion that contacts the bottom surface of the frame, and the upper surface of the support platform is provided with recesses on both sides to accommodate telescopic brackets. The bottom surface of the recesses is located above the bottom surface of the support platform. Rollers are rotatably connected to the inner bottom wall of the support platform, and friction plates are inserted into the sides of the recesses. The friction plates are located below the telescopic brackets, and the bottom surface of the friction plates is flush with the lower cut surface of the rollers.

[0010] Preferably, the support platform has snap-fit ​​grooves on both sides of one end near the fixed plate, and snap-fit ​​blocks that insert from both sides toward the center are fixedly installed on the upper surface of the fixed plate, with the snap-fit ​​blocks inserted into the snap-fit ​​grooves.

[0011] Preferably, the bottom end of the support platform is provided with a groove to accommodate half of the roller and half of the roller central shaft, and the bottom end of the groove is provided with a cover sleeve to cover the roller central shaft. The cover sleeve is fixedly connected to the support platform by screws.

[0012] Preferably, the frame is provided with a reinforcing protrusion limiting sleeve at the limiting axis, which wraps around the upper ends of the two symmetrical frames.

[0013] Preferably, the flipping platform has limit slots on the side near the transport platform and the side away from the transport platform. A fixing block is inserted into the inside of the limit slot. A winding wheel and a power source for driving the winding wheel to rotate are arranged above the fixing block. A traction rope is fixedly wound on the surface of the winding wheel. The end of the traction rope away from the winding wheel is wound and fixed to the outer surface of the frame.

[0014] Preferably, the upper surface of the flipping platform is fitted with a positioning plate for keeping the frame vertical.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This large-scale graphite product conveying system with a flipping function uses two frames to wrap around the outer surface of the graphite electrode from both sides, with snap-fit ​​blocks inserted into the snap-fit ​​grooves. A limiting sleeve covers the two symmetrical frames, a connecting frame is placed inside the gaps in the frames, and a limiting shaft is inserted into the corresponding hole. The frame connecting frame and the limiting sleeve are connected together, and the graphite electrode is held in place by a fixed semi-circle extended by a telescopic rod. This allows the graphite to be easily lifted onto the flipping platform for flipping using a transport platform and existing lifting equipment.

[0017] This large-format graphite product conveying system with a flipping function includes a transport platform comprising a support platform. The upper surface of the support platform has protrusions that contact the bottom surface of the frame. Recesses accommodating telescopic supports are located on both sides of the upper surface of the support platform, with the bottom of the recesses above the bottom surface of the support platform. Rollers are rotatably connected to the inner bottom wall of the support platform, and friction plates are inserted into the sides of the recesses. This arrangement allows the frame to be placed on the transport platform, with the frame bearing the force above the transport platform rather than above the telescopic supports. The rotation of the rollers facilitates the transfer of the device. The friction plates are located below the telescopic supports, with their bottom surfaces flush with the lower tangent of the rollers. The friction plates support the telescopic supports and prevent the transport platform from moving due to friction with the ground. This design enables the transport platform to transfer and progressively lift graphite.

[0018] This large-scale graphite product conveying system with a flipping function first lifts the horizontally placed graphite electrode using a telescopic sleeve, and then gradually raises it to a height that can be rotated using a telescopic support frame. This solves the problem that graphite electrodes placed on a flat surface cannot be raised to a height that can be rotated.

[0019] This large-scale graphite product conveying system with a flipping function has a frame with a U-shaped cross-section. Reinforcing plates are fixedly installed on the opposite sides of the frame at both ends. The reinforcing plates are used to fix the vertical and horizontal ends of the frame. This arrangement allows the end face of the frame to distribute the force evenly when under stress, preventing the end face of the frame from breaking. Attached Figure Description

[0033] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0034] like Figure 1-9 As shown, a large-size graphite product conveying system with a flipping function includes a frame 1 for fixing graphite parts from both sides, a transport platform 17 for transfer, and a flipping platform 18 for flipping. A telescopic rod 2 is fixedly installed inside the frame 1, and a fixing semi-ring 3 for contacting the graphite parts is fixedly installed at the free end of the telescopic rod 2. Frames 1 on the same side are fixedly connected by connecting plates 4 on the side. Two symmetrical frames 1 are connected by upper limiting sleeves 5. Connecting frames 6 are provided between adjacent frames 1. Multiple connecting frames 6 are fixedly connected above by lifting plates 7. Connecting frames 6, limiting sleeves 5, and frames 1 are connected by limiting shafts 8. Rotating shafts 9 are fixedly installed on both sides of the middle of the lifting plate 7. Guide rails 10 are fixedly installed on the opposite side of the connecting plates 4. A guide rail sleeve 14 is fitted onto the outer surface of the 10. A telescopic sleeve 15 is fixedly installed at the bottom end of the guide rail sleeve 14. The bottom end of the telescopic sleeve 15 on the same side is fixedly connected by a fixing plate 16. Telescopic brackets 19 are fixedly installed on both sides above the transport platform 17. A guide rail ring 20 is fixedly installed at the free end of the telescopic bracket 19. When the telescopic bracket 19 is retracted, the telescopic sleeve 15 is fully raised. The guide rail ring 20 is flush with the cross section of the guide rail sleeve 14. A bearing bracket 21 is fixedly installed in the middle of the upper part of the tilting platform 18. A receiving groove 22 for accommodating the rotation of the rotating shaft 9 is opened on the side of the upper part of the bearing bracket 21 near the transport platform 17. Support frames 23 are inserted into the front and rear ends of both sides of the tilting platform 18. The upper surface of the support frame 23 is flush with the inner bottom wall of the guide rail ring 20 when the telescopic bracket 19 is fully raised.

[0035] The cross-sectional shape of frame 1 is "U". Reinforcing plates are fixedly installed on the sides of frame 1 that are far apart from each other at the front and rear ends. The reinforcing plates are used to fix the vertical and horizontal ends of frame 1. This arrangement allows the end face of frame 1 to distribute the force evenly when subjected to force, thus preventing the end face of frame 1 from breaking.

[0036] A plug sleeve 11 is fixedly installed on the side of the frame 1 located at the front and rear ends that are far apart from each other. One of the plug sleeves 11 has a slot 12 in the middle. The two plug sleeves 11 are connected by a "T"-shaped plug plate 13. The plug plate 13 is connected to the slot 12 by a plug short rod. This arrangement can restrict the edge of the frame 1, thereby preventing the graphite electrode from falling off from both sides.

[0037] The transport platform 17 includes a support platform 171. The upper surface of the support platform 171 is provided with a protrusion 172 that contacts the bottom surface of the frame 1. The upper surface of the support platform 171 is provided with recesses 173 on both sides to accommodate the telescopic bracket 19. The bottom surface of the recesses 173 is located above the bottom surface of the support platform 171. The inner bottom wall of the support platform 171 is rotatably connected to a roller 174. A friction plate 179 is inserted into the side of the recesses 173. With this arrangement, the frame 1 can be placed on the transport platform 17, and the frame 1 is subjected to force above the transport platform 17, rather than above the telescopic bracket 19. The device is transferred by rotating the rollers 174. The friction plate 179 is located below the telescopic bracket 19, and the bottom surface of the friction plate 179 is flush with the lower cut surface of the rollers 174. By setting the friction plate 179, the telescopic bracket 19 can be supported by the friction plate 179, and the transport platform 17 can be prevented from moving by friction with the ground.

[0038] The support platform 171 has snap-fit ​​grooves 175 on both sides near the fixed plate 16. The upper surface of the fixed plate 16 is fixedly installed with snap-fit ​​blocks 176 that are inserted from both sides toward the center. The snap-fit ​​blocks 176 are inserted into the snap-fit ​​grooves 175. This arrangement allows the fixed plate 16 to be connected to the transport platform 17 and will not fall off during the transfer of the frame 1.

[0039] The bottom end of the support platform 171 is provided with a groove 177 to accommodate half of the roller 174 and half of the roller 174 central shaft. The bottom end of the groove 177 is provided with a cover sleeve 178 covering the central shaft of the roller 174. The cover sleeve 178 is fixedly connected to the support platform 171 by screws. This arrangement makes it easy to replace the roller 174.

[0040] The frame 1 has a reinforcing protrusion at the limiting shaft 8. This design ensures stable connection of the device and prevents breakage. The limiting sleeve 5 wraps around the upper ends of the two symmetrical frames 1. This design prevents the two frames 1 from separating.

[0041] Limit slots 181 are provided on the side of the flipping platform 18 closest to the transport platform 17 and the side furthest from the transport platform 17. A fixing block 182 is inserted into the inside of the limit slot 181. A winding wheel 183 and a power source 184 for driving the winding wheel 183 to rotate are provided above the fixing block 182. A traction rope 185 is fixedly wound on the surface of the winding wheel 183. The end of the traction rope 185 furthest from the winding wheel 183 is wound and fixed to the outer surface of the frame 1. During the flipping process of the frame 1, it needs to be lifted from above and then rotated by pressing one side. During the rotation, the frame 1 rotates slowly by the slow winding and releasing of the traction rope 185 under the power source 184.

[0042] The upper surface of the flipping platform 18 is fitted with a positioning plate 186 for limiting the frame 1 to remain vertical. This arrangement allows the frame 1 to be rotated to a vertical position by fitting the positioning plate 186 to limit its rotation.

[0043] In use, the graphite electrode is placed horizontally, and two frames 1 are wrapped around the outer surface of the graphite electrode from both sides, so that the snap-fit ​​block 176 is inserted into the inside of the snap-fit ​​groove 175, and the limiting sleeve 5 is covered between the two symmetrical frames 1. The connecting frame 6 is set inside the gap of the frame 1, and the limiting shaft 8 is inserted into the corresponding hole. The frame 1, connecting frame 6 and limiting sleeve 5 are connected together, and the graphite electrode is held tightly by the fixed half ring 3 through the extension of the telescopic rod 2. At this time, the rotating shaft 9 can be hoisted by the hoisting device to make the graphite electrode move within a small range.

[0044] The guide sleeve 14 is aligned with the guide ring 20 by raising the telescopic sleeve 15. The frame 1 is transferred to the top of the transport platform 17 by pulling the frame 1. At this time, the roller 174 of the support platform 171 can realize a wide range of movement of the graphite electrode.

[0045] When the graphite electrode needs to be flipped to a vertical position, the telescopic bracket 19 is raised, making the guide rail collar 20 flush with the support frame 23. The frame 1 is slid up to the flipping platform 18 and the rotating shaft 9 is sleeved inside the receiving groove 22. The support frame 23 is pulled out, and the fixing block 182 is inserted into the flipping and rising side. The traction rope 185 is fixedly wrapped around the outer surface of the frame 1. The plug plate 13 of the end of the frame 1 that needs to be lowered is pulled out. By pressing the end of the frame 1 that needs to be lowered with external force and slowly releasing it with the traction rope 185, the frame 1 can be rotated to a vertical position. The graphite electrode inside the frame 1 is adjusted to a vertical position. The external hoisting device can hoist the frame 1 from the vertical direction, so that the frame 1 is transferred from the flipping platform 18 to the designated position. The telescopic rod 2 is slowly retracted, so that the graphite electrode is slowly released, completing the flipping of the graphite electrode and disassembling the frame 1. Similarly, the reverse operation can flip the graphite electrode from a vertical position to a horizontal position.
