Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electrolytic copper production equipment, specifically to an electric lifting device for lifting electrolytic cathode copper. Background Technology
[0002] During copper electrolytic refining, excessively long copper particles adhering to the cathode can cause contact between the anode and cathode, leading to a short circuit. This short circuit negatively impacts current efficiency and the quality of the cathode copper. It results in uneven current distribution on the cathode, and the high resistance at the short-circuit contact generates additional heat, causing energy loss. This reduces the actual copper output, thus lowering current efficiency. The quality of the cathode copper also deteriorates. On the cathode where a short circuit occurs, large areas of coarse crystals and granules appear, further reducing the quality and affecting the grade. When a short circuit occurs, manual intervention is required. The cathode copper is lifted, and the excessively long copper particles are removed using specialized tools. Depending on the length of the electrolysis cycle, a single piece of cathode copper can weigh up to 200 kg. Traditional lifting devices use hand-cranked winches, resulting in high labor intensity and safety risks for workers, low efficiency, and unstable operation, all of which affect both copper yield and quality.

The lithium battery pack, motor, and reducer are mounted on the base. The lithium battery pack is electrically connected to the motor. The output shaft of the motor is connected to the input shaft of the reducer. A roller is connected to a gear on the output shaft of the reducer. A polypropylene sling is wound on the roller. The other end of the polypropylene sling passes around the fixed pulley and is fixedly connected to the hook. The two ends of the hook are hook bodies of the same structure, and the middle of the hook is a load-bearing plate connecting the two hook bodies.
[0005] Furthermore, the frame base of the machine is a cuboid frame base, the hanger is a vertical rectangular frame, a horizontal rectangular frame is fixed to the top of the vertical rectangular frame away from the base, and the fixed pulley is fixed to the lower edge of the horizontal rectangular frame.
[0006] Furthermore, the base has two symmetrical support legs or lockable pulleys fixed on its bottom surface away from the hanger.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0017] In one embodiment, an electric lifting device for electrolytic copper cathode includes: a frame 1, a 24V lithium battery pack 2, a motor 3, a reducer 4, a polypropylene sling 6, a hook 7, and a fixed pulley 8. The motor 3 is a 24V DC permanent magnet motor with a power of 1.3kW; the reducer is a planetary gear reducer (speed ratio 1:40); the lithium battery pack uses lithium iron phosphate cells (cycle life > 2000 cycles) and integrates a BMS system to achieve over-discharge protection (cutoff voltage 19.2V), providing power to the motor and controller. The frame 1 includes a frame base, which is a cuboid frame base. A hanger is vertically fixed to the upper edge of the base. The hanger is a vertical rectangular frame. A horizontal rectangular frame is fixed to the top of the vertical rectangular frame away from the base. The fixed pulley 8 is fixed to the lower edge of the horizontal rectangular frame, and the diameter of the fixed pulley 8 is 16mm. The frame is welded from 304 stainless steel square tubing (30mm x 30mm x 1.5mm), with argon arc welding used for the weld joints, and the welds are fully welded. The surface is passivated (passivation film thickness ≥ 0.5μm). Two symmetrical support legs or lockable pulleys are fixed to the bottom surface of the base on the side away from the hanger, allowing the frame to be tilted to prevent the electrolytic cathode copper from colliding with the frame during the upward lifting process. The base is equipped with a lithium battery pack 2, a motor 3, and a reducer 4. The lithium battery pack 2 is electrically connected to the motor 3. The output shaft of the motor 3 is connected to the input shaft of the reducer 4. A gear connected to the output shaft of the reducer 4 is an aluminum alloy roller 5. A polypropylene sling 6 is wound on the roller 5 and bolted to the drive roller 5. The polypropylene sling 6 is 3mm thick and 50mm wide. The other end of the polypropylene sling 6 passes over a fixed pulley 8 and is fixedly connected to a hook 7. The two ends of the hook 7 are hook bodies of the same structure. The middle of the hook 7 is a load-bearing plate connecting the two hook bodies. The load-bearing plate is a 5mm thick stainless steel plate. The polypropylene sling 6 is connected to the load-bearing plate by a D-ring. The frame 1 is equipped with a controller 9, which is electrically connected to the motor. The controller is a rotary switch that can control the forward and reverse rotation of the motor, thereby adjusting the raising and lowering of the hook.
[0018] Specifically, the connection node of the hook 7 is equipped with a triangular reinforcing rib, the hook body is "L" shaped, the top of the vertical side of the hook body protrudes horizontally from the vertical side, and the end of the horizontal side protrudes vertically from the horizontal side, which can prevent the cathode copper from falling off or becoming unstable during the lifting process. The hook body is made of No. 20 stainless steel round steel and is laser welded to the load-bearing plate.
[0019] Furthermore, it may also include a control system, with a pressure sensor and a gyroscope installed inside the load-bearing plate. The pressure sensor, gyroscope, and motor 3 are connected to the control system via signal feedback. The control system controls the speed of the motor through signal feedback from the pressure sensor and gyroscope.
[0020] When the device is in operation, the hook is hung on the cathode copper, and the rotating controller, motor drives the reducer, transmission roller and polypropylene sling to lift the cathode copper at a uniform speed, realizing the electric lifting of the cathode copper. This utility model can improve the efficiency of short circuit handling, greatly reduce the labor intensity of workers, and the device is simple and easy to operate.
