Description

Technical Field

[0001] This utility model relates to the field of electrolysis equipment technology, specifically to a device for stably clamping and preventing the cathode plate from detaching and cracking. Background Technology

[0002] The present invention relates to the technical field of cathode plates, which are key core components in industrial fields such as hydrometallurgy, electroplating, and electrolysis. Their main function is to act as the current cathode, forming the working core of the electrolytic cell together with the anode. In practical applications, the cathode plate not only needs to maintain good conductivity but must also be stably and reliably fixed to the conductive beam or supporting structure to ensure the normal operation of the entire electrolysis system.

[0003] Existing cathode plate assemblies are typically fixed to conductive beams or mounting components by welding. This method combines mechanical fixation with electrical connection, providing good structural strength and conductivity during initial installation.

[0004] In actual production, the electrolytic cell system experiences continuous vibration and stress impact due to factors such as electrolyte flow, overhead crane operations, and periodic temperature changes. As rigid connections, welded joints are prone to stress concentration zones. Under long-term cyclic stress, the weld and heat-affected zone are highly susceptible to metal fatigue, leading to problems such as weld detachment and cracking. Once weld detachment and cracking occur, it not only causes poor conductivity of the cathode plate, affecting electrolysis efficiency and product quality, but in severe cases, it can even cause the cathode plate to fall from a height, directly causing a major production safety accident. This welding method also greatly inconveniences the maintenance and replacement of cathode plates. When a damaged cathode plate needs to be replaced, the original weld must first be cut and ground before the old plate can be removed and the new plate re-welded. The entire process is complex, time-consuming, and labor-intensive, requiring specialized welding personnel and hot work permits, severely impacting production continuity.

[0005] In summary, the existing technical solutions suffer from poor vibration resistance, insufficient safety redundancy, and inconvenient replacement. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a cathode plate device for stable clamping and preventing detachment and cracking, which solves the technical problems of poor vibration resistance, insufficient safety redundancy, and inconvenient replacement in existing technical solutions.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cathode plate device for stable clamping and preventing weld detachment and cracking, comprising a mounting back plate and an electrode plate. The electrode plate has positioning holes and tensioning slots, and a conductive seat. A cable is mounted on the mounting back plate, and the cable is electrically connected to the conductive seat. The back plate has a positioning and tensioning structure, and a fastener clamping structure. This device mechanically fixes the electrode plate to the mounting back plate, replacing the traditional welding method. This design separates mechanical fixing from electrical connection, fundamentally solving the problem of weld cracking and detachment caused by vibration, and making electrode plate replacement more convenient.

[0008] Preferably, the upper end of the electrode plate is provided with an n-shaped groove, and a pair of lifting plates are fixedly installed on the mounting back plate. The pair of lifting plates are provided with insertion holes, and square tubes are provided in the insertion holes. The square tubes are placed in the n-shaped grooves. The square tubes, like crossbars, pass through the lifting plates on the mounting back plate and are inserted into the n-shaped grooves above the electrode plates. This serves to suspend the electrode plates and bear their own weight, preventing them from falling before installation or clamping, and simplifying the installation steps.

[0009] Preferably, the positioning and tensioning structure includes a positioning rod and a tensioning rod. The positioning rod is fixedly installed on the mounting back plate and inserted into the positioning hole. A rod bracket is provided on the mounting back plate, and a lead screw is rotatably installed in the rod bracket. A threaded sleeve is threadedly connected to the lead screw, and the threaded sleeve is slidably installed between the rod brackets. A motor is fixedly installed at the upper end of the rod bracket, and the motor drive end is fixedly connected to the lead screw. The tensioning rod is fixedly installed in the threaded sleeve and slidably installed in the tensioning slot. The positioning rod is inserted into the positioning hole to ensure accurate positioning of the electrode plate. The motor drives the lead screw to rotate, thereby moving the tensioning rod within the tensioning slot, positioning the electrode plate with the positioning hole as the positioning position. The tensioning rod moves upward to the top of the tensioning slot, completing the position fixation. This method can provide continuous and stable tension force, effectively resisting loosening caused by vibration.

[0010] Preferably, the fastener clamping structure includes a rear hinge connecting seat, a front hinge connecting seat, a hydraulic cylinder, and a buckle plate. The hydraulic cylinder is rotatably mounted on the rear hinge connecting seat, and the telescopic end of the hydraulic cylinder is rotatably connected to the rear end of the buckle plate. The buckle plate is rotatably mounted on the front hinge connecting seat. The hydraulic cylinder provides a strong thrust, driving the buckle plate to press the electrode plate like a buckle, thus achieving a final secure clamping.

[0011] Preferably, the conductive base is provided with a socket, and the cable is provided with a plug. The conductive base and the cable are electrically connected through the socket and the plug. This replaces the conductive method of welding or bolt fastening, making the connection between the cable and the electrode plate as simple as that of a household appliance. When replacing the electrode plate, simply unplug the plug, which greatly improves the efficiency of maintenance and replacement.

[0012] Beneficial effects

[0013] This invention provides a cathode plate device for stable clamping and preventing weld detachment and cracking. It employs a purely mechanical clamping method combining a positioning and tensioning structure with a fastener clamping structure. This effectively buffers and absorbs vibrations and thermal stresses generated during equipment operation, avoiding stress concentration and fundamentally eliminating weld cracking and detachment caused by metal fatigue. This significantly improves the long-term stability and safety of the cathode plate fixation. The n-shaped groove and square tube suspension structure enables initial mounting and positioning of the cathode plate, eliminating the need for continuous support by operators during installation, greatly reducing labor intensity and operational difficulty. Both the positioning and tensioning structure and the fastener clamping structure are automated or semi-automated, making the entire fastening process fast, precise, and standardized, shortening the installation cycle.

[0017] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Detailed description follows.

[0018] Please see Figure 1-2This utility model provides a technical solution: a cathode plate device for stable clamping and preventing detachment and cracking, including a mounting back plate 1 and an electrode plate 2. The electrode plate 2 has positioning holes 3 and tensioning slots 4, and a conductive seat 5. A cable 6 is provided on the mounting back plate 1, and the cable 6 is electrically connected to the conductive seat 5. The back plate is provided with a positioning and tensioning structure and a fastener clamping structure. This device fixes the electrode plate 2 to the mounting back plate 1 through a mechanical structure, replacing the traditional welding method. This design separates mechanical fixing from electrical connection, fundamentally solving the problem of weld cracking and detachment caused by vibration, and making it more convenient to replace the electrode plate 2.

[0019] In this embodiment, the electrode plate 2 is further configured such that an n-shaped groove 7 is formed at the upper end, and a pair of lifting plates 8 are fixedly installed on the mounting back plate 1. The pair of lifting plates 8 are provided with insertion holes, and square tubes 9 are provided in the insertion holes. The square tubes 9 are placed in the n-shaped grooves 7. The square tubes 9 are like crossbars, passing through the lifting plates 8 on the mounting back plate 1 and being inserted into the n-shaped grooves 7 above the electrode plate 2. This serves to suspend the electrode plate 2 and bear its own weight, preventing it from falling before installation or clamping, thus simplifying the installation steps.

[0020] In this embodiment, the positioning and tensioning structure includes a positioning rod 10 and a tensioning rod 11. The positioning rod 10 is fixedly installed on the mounting back plate 1 and inserted into the positioning hole 3. A rod bracket is provided on the mounting back plate 1, and a lead screw 12 is rotatably installed in the rod bracket. A threaded sleeve 13 is threadedly connected to the lead screw 12, and the threaded sleeve 13 is slidably installed between the rod brackets. A motor 14 is fixedly installed at the upper end of the rod bracket, and the driving end of the motor 14 is fixedly connected to the lead screw 12. The tensioning rod 11 is fixedly installed in the threaded sleeve 13 and slidably installed in the tensioning slot 4. The positioning rod 10 is inserted into the positioning hole 3 to ensure the accurate position of the electrode plate 2. The motor 14 drives the lead screw 12 to rotate, thereby causing the tension rod 11 to move within the tension slot 4, positioning the electrode plate 2 with the positioning hole 3 as the positioning position, and moving the tension rod 11 upward to the top of the tension slot 4 to complete the position fixation. This method can provide continuous and stable tension force and effectively resist loosening caused by vibration.

[0021] In this embodiment, the fastener clamping structure includes a rear hinge connecting seat 15, a front hinge connecting seat 16, a hydraulic cylinder 17, and a buckle plate 18. The hydraulic cylinder 17 is rotatably mounted on the rear hinge connecting seat 15, and the telescopic end of the hydraulic cylinder 17 is rotatably connected to the rear end of the buckle plate 18. The buckle plate 18 is rotatably mounted on the front hinge connecting seat 16. The hydraulic cylinder 17 provides a strong thrust, driving the buckle plate 18 to press the electrode plate 2 like a buckle, thus achieving a final secure clamping.

[0022] In this embodiment, the conductive base 5 is provided with a socket 19, and the cable 6 is provided with a plug 20. The conductive base 5 and the cable 6 are electrically connected through the socket 19 and the plug 20. This replaces the conductive method of welding or bolt fastening, making the connection between the cable 6 and the electrode plate 2 as simple as that of a household appliance. When replacing the electrode plate 2, only the plug 20 needs to be unplugged, which greatly improves the efficiency of maintenance and replacement.

[0023] Its detailed connection methods are well-known technologies in this field; such as Figure 1-2 As shown, confirm that the equipment is in a power-off state, and both the hydraulic cylinder 17 and the positioning and tensioning structure are in a released state. Specifically, the hydraulic cylinder 17 should be in a retracted state, and the buckle plate 18 should be open; the motor 14 in the positioning and tensioning structure should reverse, causing the tension rod 11 to move to the lower end of the tensioning slot 4. Lift the electrode plate 2, align its upper n-shaped groove 7 with the mounting plate 1 and insert it into the mounting location of the square tube 9 fixed by the lifting plate 8. Then insert the square tube 9, which is a detachable structure, located at the lifting plate 8. The electrode plate 2 is suspended on the square tube 9 by its own weight, completing the initial load-bearing and positioning. Gently push the electrode plate 2 so that its positioning hole 3 is aligned with and inserted into the positioning rod 10 fixed on the mounting plate 1. This step ensures that the electrode plate 2 is accurately positioned in both the vertical and horizontal directions. Start the motor 14 in the positioning and tensioning structure, and the motor 14 rotates forward, driving the lead screw 12 to rotate. The lead screw 12 drives the threaded sleeve 13 and the tensioning rod 11 to slide upwards within the tensioning slot 4 until the electrode plate 2 is fully tightened, eliminating the gap between it and the positioning rod 10, thus achieving a stable pre-tightening. The hydraulic cylinder 17 of the fastener clamping structure is activated, extending and pushing the buckle plate 18 to rotate and forcefully press against the surface of the electrode plate 2. The hydraulic system provides a huge clamping force, ensuring that the electrode plate 2 will never loosen under conditions such as vibration.

[0024] Insert the cable 6 plug 20 leading out from the mounting backplate 1 into the socket 19 of the conductive base 5 on the electrode plate 2 to complete the circuit connection. Check that all mechanisms are clamped in place and that the electrical connections are secure. Once confirmed to be correct, power can be applied for operation.

[0025] When replacement / removal is required, the steps are as follows: First, disconnect the main power supply to the equipment to ensure safe operation. Unplug the cable 6 connector 20 connected to the conductive base 5. Operate the hydraulic system to retract the hydraulic cylinder 17, causing the buckle plate 18 to rotate and loosen, releasing the strong clamping force on the electrode plate 2. Start the motor 14 to reverse, driving the lead screw 12 to slide the tension rod 11 downwards to the lower end of the tension slot 4, releasing the tension force on the electrode plate 2. Pull the electrode plate 2 out of the positioning rod 10, remove the square tube 9, and the old electrode plate 2 can be completely removed. To replace with a new plate, repeat the above installation steps.
