Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of steelmaking equipment, and in particular to a self-contained dry lubrication casting crane plate hook socket liner. Background Technology
[0002] In lifting operations, the hook, as the core component connecting the load and the lifting equipment, directly affects the stability of the entire operation and the safety of personnel. The hook liner is a crucial component inside the hook.
[0003] As a key component inside the hook, the hook retainer liner significantly reduces the wear risk caused by the hook bearing heavy loads and frequent operation. Its main function is to protect the hook from direct wear and impact, extending its service life. The liner reduces safety hazards caused by hook wear, such as breakage and detachment, thus ensuring safe lifting operations. In specific work scenarios, such as steel mills, cold-rolled sheet production and processing enterprises, and storage warehouses, the importance of the hook retainer liner is even more pronounced. These environments often involve high-intensity lifting operations, where the hook needs to frequently bear heavy loads. The hook retainer liner provides necessary protection for the hook under these extreme conditions, ensuring safe and efficient lifting operations. However, as a consumable part, the hook retainer liner lacks effective lubrication during use, and the wear rate between it and the ladle trunnion is often too rapid, leading to a shortened replacement cycle, increased maintenance costs, and the risk of operational interruptions.
[0004] Therefore, there is an urgent need to design a new type of hook with a hook liner that has good lubrication properties. Summary of the Invention
