Description

Technical Field

[0001] The invention relates to the field of metallurgy, and in particular to a hydraulic lifting device used in the smelting industry. Background Art

[0002] In the industrial production of hydrometallurgy, electrolytic extraction is often used to produce pure metals such as gold, silver, copper, zinc, nickel, and cobalt from solutions. In actual operation, the target metal is deposited on the exposed surface of the cathode plate in the electrolytic cell through electrolysis. When the deposited metal layer reaches a certain thickness, the cathode plate is lifted out of the electrolytic cell by a carrying and lifting device, and then the metal layer deposited on the cathode plate is peeled off from the cathode plate itself. Finally, the cathode plate is hoisted back into the electrolytic cell by the carrying and lifting device to continue to participate in electrolysis and be recycled.

[0003] The carrying and lifting device in the prior art generally uses a motor to drive a worm gear mechanism to drive the lifting mechanism, thereby realizing the lifting and lowering functions of the cathode plate. Although the worm gear mechanism has a self-locking function and can realize self-locking of the equipment, its efficiency is low. During the continuous lifting and lowering process, the copper sleeve inside the worm gear mechanism is very easy to wear, resulting in a low overall life of the entire carrying and lifting device. The smelter needs to frequently repair and replace the worm gear mechanism, and the time and cost costs are both high. Summary of the invention
