Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a hoisting mechanism of an electrode butt joint device. Background Art

[0002] In the industrial processes of iron and steel metallurgy, electrolysis, smelting, electroplating, etc., electrodes are key conductive consumable materials, and their length will gradually be consumed as the production process continues. In order to ensure the continuity and efficiency of the production process, it is necessary to regularly lengthen the shortened electrodes. However, in the process of electrode lengthening, due to the gravity of the electrode itself, improper operation or external factors (such as vibration, wind, etc.), the electrodes often tilt, shake or even slip. This not only affects the quality and efficiency of electrode lengthening, but may also pose a threat to equipment and personnel safety.

[0003] Traditional electrode splicing devices usually only focus on the clamping and splicing functions of the electrode, but ignore the balance and stability of the electrode during the splicing process. Therefore, during the splicing process, operators often need to spend a lot of time and energy to adjust the position of the electrode to ensure that it remains balanced and stable during the splicing process. This not only increases the labor intensity of the operators, but also reduces the efficiency and quality of the electrode splicing.

[0004] During the electrode docking process, the stability and safety of the lifting mechanism are crucial to the entire operation process. However, when lifting electrodes, traditional lifting mechanisms often lead to instability due to differences in the weight and shape of the electrodes themselves, and may even cause safety accidents. Therefore, how to design a lifting mechanism that can stably lift electrodes has become an urgent problem to be solved in the current field of electrode docking technology. Utility Model Content
