Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and in particular to an automatic cable laying device and method for a bridge. Background Art

[0002] Cable trays are metallic or non-metallic structural systems used to support and protect electrical and optical cables. They are widely used for laying power and communication lines in construction, industry, data centers, and other fields. In power and communication engineering construction, cable trays are widely used as a key carrier for cable laying. However, laying cables within cable trays requires efficient and flexible wiring methods, making them suitable for the centralized laying of various cables, including power, communication, and control cables.

[0003] Traditional cable laying methods on bridges mostly rely on manual operations, and operators need to carry out tasks such as transporting, laying, and organizing cables on the bridge. This method has many problems. First, manual laying is inefficient, especially in large-scale engineering projects, where a large amount of cable laying requires a lot of manpower and time. Second, manual operation carries a high safety risk, and operators are prone to safety accidents such as falling from heights when working on the bridge. In addition, it is difficult to ensure consistency in the arrangement and tightness of manually laid cables, which affects the quality of cable laying and its subsequent use. Although some equipment to assist in cable laying has appeared on the market, most of them have complex structures, are inconvenient to operate, and cannot adapt well to cable bridges of different specifications and shapes, and cannot meet the diverse needs of actual projects. Therefore, there is an urgent need for an efficient, safe, and adaptable automated cable laying device for bridges. Summary of the Invention
