Description

Technical Field

[0001] This utility model relates to the field of flipping device technology, specifically a flipping device for sampling anode carbon blocks. Background Technology

[0002] Since the main function of prebaked anodes in existing aluminum electrolysis technology is to introduce current into the electrolytic cell and participate in the electrochemical reaction during the aluminum electrolysis process, the quality of the anode has a great impact on the current efficiency, DC power consumption, product quality and production cost of aluminum electrolysis production. Therefore, producing high-quality prebaked anodes is crucial for electrolysis production. During the production of prebaked anodes, anode sample rods from each batch are tested and analyzed. During the sampling and testing process, the anode carbon block is rotated 180° and then placed at the bottom. In existing technologies, this is done manually by lifting the carbon block with a single clamp using an overhead crane. As a result, the operation is cumbersome, has a low safety factor, is prone to damaging the appearance quality of the carbon anode, and poses certain safety hazards to personnel during the rotation process.

[0003] A search revealed a Chinese patent (publication number: CN215573832U) that discloses a flipping device for sampling carbon blocks of aluminum electrolysis anodes. In use, the overhead crane hoists the carbon block sample to be sampled into the flipping cage, the top carbon block support rod is installed, and it is fixed to the flipping cage frame by fasteners. The operator holds the flipping disc, slowly opens the flipping cage positioning pin, and slowly rotates the flipping cage. After the flipping is completed, the flipping cage positioning pin is inserted again. After completing the above operations, the sampling operation can be carried out.

[0004] Because the tilting cage positioning pin needs to be inserted into the sleeve to fix the tilting cage, the tilting cage positioning pin needs to be inserted and removed every time it is used, which makes the process cumbersome and reduces work efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a flipping device for sampling anode carbon blocks, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a flipping device for sampling anode carbon blocks, comprising a flipping cage, the flipping cage being rectangular in shape, with openings on two corresponding side walls, through which the carbon block enters the interior. Each opening of the flipping cage is provided with a cover frame, the cover frame having multiple insertion holes, and each insertion hole having a fixing bolt threadedly connected to the flipping cage. One end of the flipping cage is connected to a first rotating shaft, and the other end is connected to multiple second rotating shafts. A first fixed frame is rotatably connected to the first rotating shaft, and a worm gear is mounted on each of the second rotating shafts, with a worm meshing with it. The second fixed frame has a second rotating groove for accommodating the worm gear and the worm, the worm gear and the worm having their own characteristics.

[0009] Furthermore, a first rotating block is installed on the first rotating shaft and is rotatably connected to the first fixed frame. The first rotating block serves to fix the first rotating shaft at an upper limit on the first fixed frame.

[0010] Furthermore, two second rotating blocks are installed on the second rotating shaft and placed in the second rotating groove. The two second rotating blocks are respectively set on both sides of the worm gear. The second rotating blocks on the second fixed frame play a role in limiting and fixing the worm gear.

[0011] Furthermore, a third rotating block is installed on the worm gear, and the third rotating block is rotatably connected to the second rotating groove.

[0012] Furthermore, the first and second fixing frames are connected to the same base plate.

[0013] Furthermore, a turntable is installed at the top of the worm gear.

[0014] Furthermore, four carbon block positioning components are welded to the inner walls of the frame on both the front and rear sides of the tilting cage. Each carbon block positioning component has a carbon block positioning bolt on its inner side that is perpendicular to the frame and threadedly connected.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a flipping device for sampling anode carbon blocks, which has the following advantages:

[0017] The anode carbon block sampling and turning device uses a worm gear to drive a worm wheel to rotate. The second rotating shaft installed on the worm wheel drives the carbon block in the turning cage to turn. Because the worm gear and worm wheel have a self-locking function, only the worm gear can drive the worm wheel, and the worm wheel cannot drive the worm gear. This eliminates the need for a positioning pin to limit the turning cage during the turning process, thus improving the convenience of use and work efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 The present invention discloses a flipping device for sampling anode carbon blocks, comprising a flipping cage 1 and a base plate 10. A first fixing frame 6 and a second fixing frame 7 are welded to the top two sides of the base plate 10, respectively. The flipping cage 1 is rectangular, and each of its two corresponding side walls is provided with an opening. The carbon block enters the interior through the opening. A cover frame 2 is provided at each opening of the flipping cage 1. Multiple insertion holes are opened at the edge of the cover frame 2, and a fixing bolt 3 is inserted into each insertion hole. The flipping cage 1 has threaded holes corresponding to the insertion holes. The fixing bolt 3 is rotated to enter the threaded holes of the flipping cage 1, thereby fixing the cover frame 2 onto the flipping cage 1 for fixing the carbon block on the flipping cage 1.

[0023] One end of the tilting cage 1 is connected to a first rotating shaft 4, and the other end is connected to a second rotating shaft 5. A first rotating block is installed on the first rotating shaft 4, and a first rotating groove is opened on the first fixed frame 6. The first rotating shaft 4 and the first rotating block enter the first rotating groove and are rotatably connected. The first rotating block plays the role of fixing the first rotating shaft 4 at the upper limit on the first fixed frame 6.

[0024] A worm gear 8 is installed on the second rotating shaft 5, and two second rotating blocks 14 are installed on the second rotating shaft 5. The two second rotating blocks 14 are respectively located on both sides of the worm gear 8. A second rotating groove is provided on the second fixed frame 7. The second rotating shaft 5 passes through the second rotating groove, and the second rotating blocks 14 are placed in the second rotating groove, so that the second rotating blocks 14 play the role of limiting and fixing the second rotating shaft 5 on the second fixed frame 7.

[0025] A worm 9 is also installed on the second rotating groove. The worm 9 is meshed with the worm wheel 8. The worm wheel 8 and the worm 9 have their own characteristics. A third rotating block 15 is installed on the worm 9 and is rotatably connected to the second rotating groove, which serves to limit and fix the worm 9. A turntable 11 is installed at the top of the worm 9. By rotating the turntable 11, the worm 9 is driven to rotate. The worm 9 meshes with the worm wheel 8, so that the worm wheel 8 drives the tilting cage 1 to rotate through the second rotating shaft 5. Due to the characteristics of the worm wheel 8 and the worm 9, only the worm 9 can drive the worm wheel 8 to rotate, and vice versa, so that the tilting cage 1 can stay at any angle.

[0026] Four carbon block positioning parts 12 are welded to the inner walls of the frame on both the front and rear sides of the tilting cage 1. Each carbon block positioning part 12 has a carbon block positioning bolt 13 on its inner side that is perpendicular to the frame and threadedly connected.

[0027] In summary, when using the anode carbon block sampling flipping device, at the top opening of the flipping cage 1, use a tool to rotate the fixing bolt 3 to disengage the fixing bolt 3 from the flipping cage 1. Then, remove the cover frame 2 from the flipping cage 1. Use hoisting equipment to hoist the carbon block along the opening of the flipping cage 1 and place it inside the flipping cage 1. Then, close the cover frame 2 and use a fixing nut to fix the flipping cage 1 and the cover frame 2.

[0028] Then, the turntable 11 is rotated, and the worm 9 drives the second rotating shaft 5 connected to the worm wheel 8 to rotate, thereby causing the tilting cage 1 to tilt. Since the worm wheel 8 and the worm 9 have self-locking characteristics, the worm wheel 8 cannot drive the worm 9, and only the worm 9 can drive the worm wheel 8. When the tilting cage 1 tilts, the carbon block is tilted.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
