Description

Technical Field

[0001] This utility model relates to the field of cathode carbon block lifting tools, specifically a lifting tool for cathode carbon blocks in an electrolytic cell. Background Technology

[0002] Electrolytic cell cathode carbon blocks are carbonaceous block materials made from high-quality anthracite, coke, graphite, etc., through processes such as calcination, molding, roasting, and even graphitization. They are a core component of aluminum electrolytic cells, mainly built at the bottom of the cell. During the hoisting of cathode carbon blocks, steel wire ropes are commonly used. This method involves looping the steel wire rope around both ends of the cathode carbon block, with the edges and corners acting as stress points. These edges and corners experience significant stress during hoisting, easily leading to damage and affecting the cathode's performance. However, a specialized hoisting tool for cathode carbon blocks (CN216997295U) uses a square steel structure for the bottom support assembly. This not only increases the contact area at the hanging point, ensuring stability during hoisting, but also avoids using the edges and corners as stress points, preventing excessive localized stress and damage. This also prevents the cathode carbon blocks from swaying or being damaged during hoisting due to issues with the hoisting method or tools. Furthermore, by increasing the roughness of the bottom contact surface and adding anti-slip strips, the contact between the bottom support assembly and the cathode carbon block is increased, reducing the wear of tools on the cathode carbon block, enabling rapid cathode hoisting, improving work efficiency, and ensuring safety.

[0003] While the aforementioned technology can prevent the cathode carbon block from shaking or being damaged during hoisting due to issues with the hoisting method or tools, it has a problem that the clamped surface of the cathode carbon block cannot be cleaned when it is being held. If the clamped surface is covered with dust, carbon dust, oil, or residual binder from roasting, it will reduce the coefficient of friction between the clamping plate and the carbon block. During hoisting, especially during lifting, transport, or high-altitude positioning, the carbon block may slip or even fall due to insufficient friction, causing equipment damage or personal injury. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting tool for cathode carbon blocks in electrolytic cells, so as to solve the problem mentioned in the background art that the lifting tools on the market cannot clean the clamped surface of the cathode carbon blocks when they clamp them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for cathode carbon blocks in an electrolytic cell, comprising a suspension beam, a support frame installed at the bottom of the suspension beam, a first slider slidably connected to both ends of the support frame, a clamping plate at the bottom of each of the two first sliders, a support bar at both ends of each of the two clamping plates, a second slider slidably connected between the two support bars on both sides, a cleaning bar at the bottom of each of the two second sliders, a first reciprocating screw threadedly connected to the two support bars on both sides and rotatably connected to the two second sliders, a first limiting rod slidably connected to the two support bars on both sides and slidably connected to the second slider, a driving component for moving the second sliders on the support frame, and a cleaning component for cleaning the cleaning bar on the support bars.

[0006] Preferably, the drive assembly includes two first connecting plates respectively disposed at both ends of one side of the support frame. Each of the two first connecting plates is provided with a first rack on one side. The two support bars on one side are respectively rotatably connected to two first reciprocating screws, and one end of each of the two rotating bars is provided with a first rotating gear that meshes with the two first racks.

[0007] Preferably, the cleaning component includes two support plates respectively disposed at one end of the two support bars, and an L-shaped plate is also provided at the bottom of the two support bars. A third slider is slidably connected between the two support plates and the two L-shaped plates, and a cleaning roller is rotatably connected to one end of each of the two third sliders.

[0008] Preferably, a second reciprocating screw threaded inside the two third sliders is rotatably connected between the two support plates and the two L-shaped plates, and a second limiting rod slidably connected inside the two third sliders is also provided between the two support plates and the two L-shaped plates.

[0009] Preferably, the other two ends of the support frame are provided with second connecting plates, one end of each of the two second connecting plates is provided with a second rack, the top of the two support plates are respectively rotatably connected to a rotating shaft connected to two second reciprocating screws, and one end of each of the two rotating shafts is provided with a second rotating gear that meshes with the two second racks.

[0010] Preferably, one end of the support frame is provided with a drive motor, the output end of the drive motor is provided with a bidirectional lead screw rotatably connected inside the support frame, and the threads at both ends of the bidirectional lead screw are respectively threaded into the two first sliders. A first lifting ring is provided at the top of the suspension beam, and second lifting rings are symmetrically provided at both ends of the top of the suspension beam. Support frames are symmetrically provided at both ends of the bottom of the suspension beam.

[0011] Preferably, both ends of the two cleaning strips are connected to flexible plates by springs, and both cleaning strips are made of flexible material. The sides of the two clamps that are close to each other are provided with anti-slip layers.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By sliding the two clamping plates closer together, the cathode carbon block is clamped. The parallel clamping of the two sides of the carbon block is achieved by moving them closer together, resulting in uniform pressure distribution. This avoids the local stress concentration caused by traditional point or line contact and reduces the risk of edge cracking or internal microcracks in the carbon block.

[0013] The cleaning strip is moved by the drive component, which achieves the effect of cleaning the clamping surface of the cathode carbon block. It can effectively remove dust, carbon debris, oil stains or residual binder from the clamping surface, avoid the decrease in friction coefficient between the clamping plate and the carbon block caused by impurities, and improve the stability of clamping.

[0014] The cleaning components are designed to clean the cleaning strips. After cleaning the surface of the charcoal blocks, the cleaning strips will have charcoal powder, oil, roasting residue and other impurities attached to them. This can cause uneven force when in contact with the charcoal block surface, which may form scratches or indentations on the charcoal block surface. Cleaning the cleaning strips can maintain the cleaning effect of the cleaning strips on the charcoal blocks and reduce the residue of impurities. Attached Figure Description

[0017] 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.

[0018] This utility model provides the following technical solution: a lifting device for cathode carbon blocks in an electrolytic cell: Example 1: To address the problem that existing lifting devices cannot clean the clamped surface of cathode carbon blocks when holding them, the following is disclosed: a suspension beam 1, a support frame 2 installed at the bottom of the suspension beam 1, first sliders 3 slidably connected to both ends inside the support frame 2, clamping plates 4 at the bottom of each of the two first sliders 3, support bars 5 at both ends of each of the two clamping plates 4, and second sliders 6 slidably connected between the two support bars 5 on both sides, with cleaning bars 7 (such as...) at the bottom of each of the two second sliders 6. Figure 1 , Figures 3-5 As shown), it is used to clean the cathode carbon block. Two support bars 5 on both sides are rotatably connected to a first reciprocating screw threaded into the two second sliders 6. A first limiting rod is also slidably connected into the second sliders 6 between the two support bars 5 on both sides. The support frame 2 is equipped with a driving assembly for moving the second sliders 6. The driving assembly includes two first connecting plates 9 respectively located at both ends of one side of the support frame 2. Each of the two first connecting plates 9 has a first rack 10 on one side (as shown). Figure 1 and Figure 5 As shown), two support bars 5 on one side are rotatably connected to two first reciprocating lead screws, and one end of each of the two rotating columns is provided with a first rotating gear 11 that meshes with two first racks 10. One end of the support frame 2 is provided with a drive motor, and the output end of the drive motor is provided with a bidirectional lead screw rotatably connected inside the support frame 2. The threads at both ends of the bidirectional lead screw are respectively threaded into the two first sliders 3 (as shown). Figure 4 As shown), it is used to drive the first slider 3 to move. The top of the suspension beam 1 is provided with a first lifting ring 19. The two ends of the top of the suspension beam 1 are also symmetrically provided with second lifting rings 20. The two ends of the bottom of the suspension beam 1 are symmetrically provided with support frames 21. The two ends of the two cleaning strips 7 are connected to flexible plates 8 by springs. Both cleaning strips 7 are made of flexible material. The two clamping plates 4 are provided with anti-slip layers on the side that is close to each other.

[0019] When it is necessary to clamp the cathode carbon block, the drive motor can be started to rotate the bidirectional lead screw, thereby causing the two first sliders 3 and the clamping plate 4 to move closer to each other (e.g., Figures 1-4As shown), when the clamping plate 4 moves, it also drives the support bar 5 to move synchronously. Then, under the action of the first rack 10, it drives the first rotating gear 11 to rotate, thereby driving the rotating column to rotate, and further driving the first reciprocating screw to rotate. Subsequently, under the action of the first limiting rod, it drives the second slider 6 and the cleaning bar 7 to reciprocate (as shown). Figure 1 , Figures 3-5 As shown), because the length of the support bar 5 is greater than the length of the clamping plate 4, the cleaning bar 7 will first contact the surface of the cathode carbon block, thereby cleaning the clamped surface of the carbon block. After cleaning, the cleaning bar 7 moves away from the cathode carbon block, and then the clamping plate 4 continues to move and clamp and fix it. The flexible plate 8 can increase the cleaning area of ​​the cathode carbon block, and the first lifting ring 19 and the second lifting ring 20 can be connected to the lifting equipment (such as...). Figure 1 and Figure 2 As shown, the different configurations of the first lifting ring 19 and the second lifting ring 20 can accommodate lifting equipment of different sizes, while the support frame 21 can provide support when the lifting device is not in use, and the anti-slip layer can be made of polyurethane rubber, which can further improve the stability of the clamping.

[0020] Example 2: Unlike Example 1, the cleaning component can clean the cleaning strip 7. It is disclosed that: the support strip 5 is provided with a cleaning component for cleaning the cleaning strip 7. The cleaning component includes two support plates 12 respectively disposed at one end of the two support strips 5, and L-shaped plates 13 are also provided at the bottom of the two support strips 5. A third slider 14 is slidably connected between the two support plates 12 and the two L-shaped plates 13. A cleaning roller 15 is rotatably connected to one end of each of the two third sliders 14 (e.g., ...). Figure 6 As shown), it is used to clean the cleaning strip 7. A second reciprocating screw threaded into the two third sliders 14 is rotatably connected between the two support plates 12 and the two L-shaped plates 13. A second limiting rod slidably connected into the two third sliders 14 is also provided between the two support plates 12 and the two L-shaped plates 13. Second connecting plates 16 are provided at both ends of the other side of the support frame 2. A second rack 17 is provided at one end of each of the two second connecting plates 16. Rotating shafts connected to the two second reciprocating screws are rotatably connected to the tops of the two support plates 12, and a second rotating gear 18 meshing with the two second racks 17 is provided at one end of each of the two rotating shafts. Figure 3 , Figure 4 and Figure 6 (As shown).

[0021] When the clamping plate 4 moves the support bar 5, the second rotating gear 18 will rotate under the action of the second rack 17, thereby driving the rotating shaft to rotate (e.g. Figure 3 , Figure 4 and Figure 6As shown), and further drives the second reciprocating screw to rotate, and then under the action of the second limit rod, it drives the third slider 14 to reciprocate up and down, thereby driving the cleaning roller 15 to rise and fall (as shown). Figure 6 As shown, when the cleaning strip 7 reaches the position of the cleaning roller 15, the cleaning roller 15 will roll on the surface of the cleaning strip 7 and clean it.
