Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a folding ladder for anchor lip welding. Background Technology

[0002] Anchor platforms are an important component of ship mooring equipment, located at the upper end of the anchor chain canopy. They are typically made of cast steel and include the anchor claw seat, anchor lip, anchor chain hole, and base. Their main function is to support the anchor claw, ensuring it can smoothly hook onto the anchor chain, thus securing the ship's position. The design and strength of the anchor platform must be sufficient to withstand the force and pressure exerted on the anchor claw during anchoring. With the development of the shipbuilding industry, shipyards are building an increasing variety of ships, resulting in a greater diversity in the size and type of anchor platforms and anchor lips. To address the issue of personnel access during anchor lip welding, shipyards typically use temporary scaffolding or fabricate single-type tooling ladders. This consumes significant manpower and resources and still cannot achieve the same method for welding anchor lips of different types and sizes. To improve anchor lip welding efficiency, a folding ladder is needed; however, existing folding ladders still have the following shortcomings:

[0003] When using existing folding ladders, the construction time is relatively long, and they are not suitable for different ship types and anchor lips. As a result, the folding ladders are inconvenient to carry and cumbersome to set up, which leads to a decrease in the practicality and efficiency of the folding ladders.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a special folding ladder for anchor lip welding. Utility Model Content
