Description

Technical Field

[0001] This invention relates to the field of robots for the maintenance of main cables of suspension bridges, specifically a robot for the maintenance of main cables of suspension bridges. Background Technology

[0002] The suspension bridge main cable inspection robot is a robotic system specifically designed for the inspection and maintenance of the main cables of suspension bridges. The main cable is the core component of a suspension bridge, bearing significant loads on the bridge structure. Because the main cables are typically located at high altitudes, span large distances, and are difficult to access, conventional manual inspection methods are often difficult and dangerous. The suspension bridge main cable inspection robot, through its autonomous movement and manipulation capabilities, can perform inspection, repair, and maintenance work on the surface of the main cables. It can collect real-time status information of the main cables and detect and identify potential damage, corrosion, or loosening.

[0003] The following problems exist in the traditional maintenance of the main cable of a suspension bridge:

[0004] 1. Traditional manual methods for inspecting the main cable of a suspension bridge are inefficient. The main cable is several kilometers long, and manual methods require closing the bridge or building a high-altitude operating platform, resulting in long inspection cycles and low efficiency.

[0005] 2. Manual methods cannot conduct a comprehensive and detailed inspection of the main cable. Workers can only visually inspect and perform simple tapping tests on some exposed parts, and cannot detect defects inside the main cable and in each layer of rope fibers.

[0006] 3. Manual methods cannot provide timely and effective online repairs for detected defects; only temporary measures or repairs can be performed during major overhauls, which poses significant risks.

[0007] Based on this, the present invention designs a suspension bridge main cable maintenance robot to solve the above-mentioned problems. Summary of the Invention
