Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a large-span cable bridge. Background Art

[0002] With the development of modern industry and construction, cable installation requirements are constantly increasing. Traditional cable trays are mostly fixed-length designs. Long-span installations require multiple cable trays to be spliced together, increasing installation complexity and cost. Furthermore, the connections can be unstable, and their structural strength is limited. They are unable to withstand the weight of cables and external loads over long spans, leading to deformation and sagging. In large industrial plants, stadiums, exhibition halls, and other venues, due to the large spans and the large number of cables required, traditional short-span cable trays are insufficient. Cable trays suitable for long-span installations are urgently needed. Furthermore, with the increase in electrical equipment and power loads, the safety and reliability requirements for long-span cable trays are increasing. They must possess excellent fire resistance, corrosion resistance, and earthquake resistance, and be easy and quick to install and maintain to reduce operating costs. Furthermore, with the current trend towards energy conservation and environmental protection, long-span cable trays also need to consider energy conservation and consumption reduction, such as optimizing the structure to improve heat dissipation to reduce energy loss and adopting environmentally friendly materials and production processes to minimize environmental impact.

[0003] However, as for the current large-span cable trays, traditional cable trays are mostly designed with fixed lengths. When laying over large spans, multiple trays need to be spliced together, which increases the complexity and cost of installation. The connection parts may be unstable, and their structural strength is limited. They are unable to withstand the weight of cables and external loads over large spans, and are prone to deformation, damage and other problems, which need to be improved. Utility Model Content
