Abstract
Description
Technical Field
[0001] This utility model relates to the field of anchor chain processing technology, specifically to an anchor chain grinding device. Background Technology
[0002] An anchor chain is a specialized chain that connects the anchor to the ship's hull and transmits the anchor's holding force. It typically consists of anchor end links, intermediate links, and terminal links. Based on the structure of the chain links, anchor chains can be divided into two types: studded anchor chains and studless anchor chains, with the former being stronger than the latter. Based on the manufacturing method, anchor chains can be divided into cast steel anchor chains and welded anchor chains, etc. The length of an anchor chain is measured in sections, with each section having a standard length of 27.5 meters. Sections are connected using connecting links or shackles. Typically, a 10,000-ton ship uses approximately 12 sections of chain per side for its main anchor.
[0003] Anchor chain production often results in welds with protrusions or burrs due to welding, extrusion, heating, stretching, and wear. These burrs need to be cleaned promptly, requiring the use of anchor chain grinding equipment. However, existing anchor chain grinding equipment has a simple structure, and grinding debris can fly onto workers during operation, posing a safety hazard. Furthermore, some narrow corners inside the anchor chain are difficult to grind, and the varying sizes of anchor chains prevent some from being effectively ground. Utility Model Content
