Description

Technical Field

[0001] This utility model relates to the field of anode guide rod clamping technology, and in particular to an anode guide rod fixing clamp for aluminum electrolysis cells. Background Technology

[0002] In aluminum electrolysis production, the anode guide rod is the core component of the anode system of the electrolytic cell. It plays an important role in connecting the anode busbar and the anode carbon block, conducting current, and supporting the anode structure. The role of the fixing fixture is to ensure that the anode guide rod remains stably positioned during the operation of the electrolytic cell, preventing it from shaking, shifting, or falling off, thereby ensuring the stability of current conduction and the normal operation of electrolysis production.

[0003] The anode guide rod is relatively large, and its installation and fixation require hoisting to the designated position by an overhead crane and then clamping with a fixing fixture. However, existing anode guide rod fixing fixtures mostly use a bolt locking structure to compress the outer wall of the guide rod. This clamping method has obvious defects: on the one hand, excessive compression can easily damage the outer wall of the anode guide rod; on the other hand, if the clamping structure becomes loose, the guide rod may fall or shift, thereby damaging the anode carbon block connected to its bottom and affecting the continuity of electrolysis production. Therefore, this application proposes an anode guide rod fixing fixture for aluminum electrolysis cells. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anode guide rod fixing clamp for aluminum electrolysis cells, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anode guide rod fixing clamp for an aluminum electrolysis cell, comprising:

[0006] The main body is shaped like a square column, with a through-hole at the top and slots on both sides that communicate with the through-hole.

[0007] The swing clamp is provided in two sets. The cross-section of the swing clamp is teardrop-shaped. A fixed shaft is installed at the top of the side wall of each of the two slots. The top of the two sets of swing clamps are respectively rotated and sleeved on the corresponding fixed shaft.

[0008] The guide rod is inserted through the socket, and slots are provided on both sides of the guide rod. The bottom ends of the two swinging clips can be engaged in the slots on both sides of the guide rod.

[0009] The casing is fitted over the outside of the main body, with the inner wall of the casing fitting snugly against the outer wall of the main body.

[0010] A fixing tube is installed at the center of the top of the casing and communicates with its interior, and the fixing tube is sleeved on the outside of the guide rod;

[0011] The screw is inserted laterally between the fixed tube and the guide rod.

[0012] Optionally, a second through hole is provided on the side of the fixing tube, and a through first through hole is provided on the side of the guide rod above the slot. A fixing block is installed at one end of the top of the sleeve. A threaded groove is provided on the side of the fixing block near the fixing tube. One end of the screw passes through the first through hole and the second through hole and is threaded into the threaded groove on the side of the fixing block.

[0013] Optionally, connecting plates are installed at both ends of the top of the main body, and limiting grooves are opened at the top of the two connecting plates. First through-holes are opened at both ends of the top of the casing, and annular grooves are opened at both ends of the side wall of the screw. The tops of the two connecting plates pass through the corresponding first through-holes, and the limiting grooves at the tops of the two connecting plates are respectively engaged in the annular grooves at both ends of the screw.

[0014] Optionally, the middle part of the inner wall of the limiting groove is protruding, and the protruding part of the inner wall of the limiting groove is engaged in the annular groove at the end of the screw, and the two sides of the inner wall of the limiting groove are in contact with the outside of the screw.

[0015] Optionally, a limiting block is fitted on the top of each of the two connecting plates. The top of the limiting block has two symmetrically distributed second openings, and the shape of the two second openings on the limiting block is adapted to the shape of the top of the connecting plate. The second openings on the limiting block are fitted on the top of the connecting plate. A first screw hole is opened on the side of the connecting plate, and a second screw hole is opened on the side of the limiting block, which is inserted through the second opening. A bolt is inserted between the first screw hole and the second screw hole. An arc-shaped groove adapted to the outer wall of the screw is opened at the bottom of the limiting block.

[0016] Optionally, the main body may also include:

[0017] There are four notches, which are arranged in a circular array around the top of the socket with the vertical axis of the socket as the center.

[0018] There are four shafts, each installed in one of the four notches;

[0019] The rollers are arranged in four parts and are respectively fitted onto the corresponding shafts;

[0020] The top of the socket is designed with a funnel-shaped opening.

[0021] Optionally, a mounting bracket is fixedly installed on one side of the main body. The mounting bracket is configured as an inverted T-shape, and a notch is opened on the side of the casing near the mounting bracket, with the bottom end of the notch extending to the bottom of the casing.

[0022] Optionally, when the swinging clip is in a vertical position, both sides of its bottom end extend into slots. When the guide rod is connected to the fixed tube, the horizontal height of the bottom end of the slot on the side wall of the guide rod is lower than the bottom end of the sleeve. When the swinging clip is fitted into the slot, the inner wall of the top of the slot is in contact with the outer side of the swinging clip.

[0023] The beneficial effects of this utility model are:

[0024] The main body is securely fixed to the electrolytic cell by welding the mounting frame, laying the foundation for subsequent operations. Before installing the guide rod, the connection between the casing and the guide rod must be completed in advance: insert the guide rod into the casing and the fixing tube, and use a screw to pass through the fixing tube at the top of the casing and the guide rod to achieve the initial connection between the two. Then, use an overhead crane to lift the guide rod with the casing connected to it to the top of the main body and slowly lower it. During the descent, the guide rod is precisely inserted into the corresponding insertion hole of the main body. Then, adjust the angle of the guide rod so that the casing is completely fitted on the outside of the main body. The inner wall of the casing squeezes the swinging clip, causing it to embed into the slot on the outer wall of the guide rod, forming a mechanical limit and effectively preventing the guide rod from falling further, thus completing the initial fixation of the guide rod and the main body. This mechanical fitting and locking method, which relies on the descent of the guide rod and casing, significantly improves the connection stability compared to the traditional extrusion clamping process. It can effectively resist the influence of vibration and other factors and prevent the guide rod from loosening and falling off.

[0025] After the guide rod is connected to the main body, the two connecting plates at the top of the main body play a crucial role. The limiting groove at the top of the connecting plate will be locked in the annular grooves at both ends of the screw. With the positional constraint of the two connecting plates, the horizontal movement and rotation of the screw are restricted, ensuring that the screw is firmly inserted between the fixed tube and the guide rod, further enhancing the connection strength. Finally, the screw is locked a second time with the help of the limiting block. Through the connection between the limiting block and the connecting plate, the position of the screw is locked, which further fixes the guide rod to the main body, preventing the guide rod from moving upward. This achieves reliable installation of the guide rod between the main body and ensures the stable operation of the electrolytic cell equipment. Attached Figure Description

[0043] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0044] Please see Figure 1 and Figure 8This utility model provides a technical solution: an anode guide rod fixing clamp for an aluminum electrolytic cell, comprising a main body 1, which is shaped like a square column. A through-hole 12 is provided on the top of the main body 1, and slots 13 communicating with the through-hole 12 are provided on both sides of the main body 1. A fixing shaft 14 is installed at the top of the side wall of each of the two slots 13. A swinging clip 15 is sleeved on each of the two fixing shafts 14, and the cross-section of the swinging clip 15 is teardrop-shaped. A vertical guide rod 2 is inserted through the through-hole 12. A slot 22 is provided on both sides of the guide rod 2. The bottom ends of the two swinging clips 15 can be engaged in the slots 22 on both sides of the guide rod 2. A shell 3 is sleeved on the outside of the main body 1, and the inner wall of the shell 3 is fitted with the outer wall of the main body 1. A fixing tube 32 communicating with the inside of the shell 3 is installed at the center of the top of the shell 3, and the fixing tube 32 is sleeved on the outside of the guide rod 2. A screw 4 is inserted horizontally between the fixing tube 32 and the guide rod 2.

[0045] See Figure 1 and Figure 2 The side of the fixing tube 32 is provided with a second through hole 33, and the side of the guide rod 2 and above the slot 22 is provided with a through first through hole 21. A fixing block 34 is installed at one end of the top of the sleeve 3. A screw groove 35 is provided on the side of the fixing block 34 near the fixing tube 32. One end of the screw 4 passes through the first through hole 21 and the second through hole 33 and is threaded into the screw groove 35 on the side of the fixing block 34. By inserting the screw 4, the position of the guide rod 2 can be restricted inside the fixing tube 32. The connection between the screw 4 and the screw groove 35 on the side of the fixing block 34 can achieve the purpose of pre-fixing the screw 4.

[0046] See Figure 1 , Figure 2 and Figure 3 Both ends of the top of the main body 1 are equipped with connecting plates 5. Limiting grooves 51 are opened at the top of the two connecting plates 5. Both ends of the top of the sleeve 3 are provided with first through-holes 36. Both ends of the side wall of the screw 4 are provided with annular grooves 41. The tops of the two connecting plates 5 pass through the corresponding first through-holes 36, and the limiting grooves 51 at the tops of the two connecting plates 5 are respectively engaged in the annular grooves 41 at both ends of the screw 4. Through the engagement connection between the two connecting plates 5 and the screw 4, the screw 4 can not move horizontally, thereby locking the screw 4.

[0047] See Figure 4The middle part of the inner wall of the limiting groove 51 is protruding. The protruding part of the inner wall of the limiting groove 51 is engaged in the annular groove 41 at the end of the screw 4, and the two sides of the inner wall of the limiting groove 51 are in contact with the outside of the screw 4. In this way, the top of the connecting plate 5 can be stably engaged in the annular groove 41 at the end of the screw 4. Under the engaging action of the two connecting plates 5, the screw 4 can be prevented from moving left and right, so that one end of the screw 4 can be stably connected in the screw groove 35 on the side of the fixing block 34. This allows the screw 4 to always be inserted between the fixing tube 32 and the guide rod 2, which can increase the stability of the connection between the guide rod 2 and the fixing tube 32.

[0048] See Figure 2 and Figure 7 Each of the two connecting plates 5 has a limiting block 6 fitted at its top. The top of the limiting block 6 has two symmetrically distributed second openings 61, and the shape of the two second openings 61 on the limiting block 6 matches the shape of the top of the connecting plate 5. The second openings 61 on the limiting block 6 are fitted onto the top of the connecting plate 5. The side of the connecting plate 5 has a first screw hole 52 that penetrates the limiting groove 51, and the side of the limiting block 6 has a second screw hole 63 that penetrates the second opening 61. A bolt 7 is inserted between the first screw hole 52 and the second screw hole 63. The bottom of the limiting block 6 has an arc-shaped groove 62 that matches the outer wall of the screw rod 4. Through the insertion and cooperation of the limiting block 6 and the connecting plate 5, the position of the screw rod 4 can be further fixed. And the bolt 7 can connect the limiting block 6 and the connecting plate 5 together. In this way, the sleeve 3 and the guide rod 2 cannot move upward on the main body 1, thereby further improving the stability of the fixed clamping of the guide rod 2.

[0049] See Figure 4 and Figure 5 The main body 1 has four notches 16 arranged in a circular array around the insertion hole 12 on its top. A rod shaft 17 is fixedly installed in each notch 16, and a roller 18 is rotatably sleeved on each rod shaft 17. The top of the insertion hole 12 is set as a funnel-shaped opening. The rollers 18 around the top of the insertion hole 12 can prevent the bottom of the guide rod 2 from being damaged due to collision when it docks with the insertion hole 12. When the top of the guide rod 2 contacts the rollers 18, the rotation of the rollers 18 can guide the bottom of the guide rod 2 to move towards the insertion hole 12. With the funnel-shaped opening at the top of the insertion hole 12, the docking speed of the guide rod 2 and the insertion hole 12 can be improved.

[0050] See Figure 1 and Figure 2A mounting bracket 11 is fixedly installed on one side of the main body 1. The mounting bracket 11 is set as an inverted T-shape. The mounting bracket 11 is installed on the electrolytic cell by welding, thereby fixing the position of the main body 1. In this way, the main body 1 can support and position the guide rod 2 and the sleeve 3. The sleeve 3 has a notch 31 on the side near the mounting bracket 11, and the bottom end of the notch 31 extends to the bottom of the sleeve 3. The notch 31 on the side wall of the sleeve 3 allows it to be smoothly fitted onto the outside of the main body 1.

[0051] See Figure 2 and Figure 5 When the swinging clip 15 is in a vertical position, both sides of its bottom end extend out of the slot 13. When the guide rod 2 is connected to the fixed tube 32, the horizontal height of the bottom end of the slot 22 on the side wall of the guide rod 2 is lower than the bottom end of the sleeve 3. When the swinging clip 15 is fitted into the slot 22, the inner wall of the top of the slot 22 is in contact with the outer side of the swinging clip 15. During the connection process between the sleeve 3 and the main body 1, when the sleeve 3 does not contact the swinging clip 15, the slot 22 part of the outer wall of the guide rod 2 has already descended to the swinging clip. At the position of component 15, as the sleeve 3 continues to descend, the sleeve 3 presses against the outer end of the swinging clip 15, causing the swinging clip 15 to rotate around the top fixed shaft 14 in the slot 13 toward the slot 22. In this way, the inner end of the swinging clip 15 can fit into the slot 22. When the sleeve 3 is completely covered outside the main body 1, the swinging clip 15 also moves to the top of the slot 22, thereby fixing the position of the guide rod 2 in the insertion hole 12 inside the main body 1.

[0052] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
