Description

Technical Field

[0001] This utility model relates to the field of shackle technology, specifically a labor-saving device for installing and removing shackles on navigation beacon chains. Background Technology

[0002] The shackle of a navigational aid chain is an important component connecting the anchor chain of a navigational aid. It is used to fix the navigational aid and ensure its navigational function. It is usually made of high-strength alloy steel and has tensile, corrosion and wear resistance properties. The shackle design must ensure a stable connection and prevent the navigational aid from drifting due to pin detachment. Common types include tapered pin shackles and cotter pin shackles. New types of shackles also improve disassembly efficiency and safety through optimized structure. They are key components for the reliable operation of the navigational aid system.

[0003] In traditional work processes, the installation and disassembly of shackles mainly rely on manual labor using tools such as wrenches and pry bars. This method has significant drawbacks. Manual operation requires a lot of physical strength, especially when dealing with large shackles. It is not only inefficient, but also difficult to ensure installation accuracy, which can easily lead to loose shackle connections. When operating manually, due to the lack of precise positioning and a stable force application structure, operational errors are prone to occur, leading to safety accidents such as component damage or personnel injury.
