Description

Technical Field

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

[0002] Cable tray is a combination rack used to support and protect cables during the cable installation process. Cable trays are divided into trough type, tray type, ladder type and grid type structures. They are composed of brackets, supports and installation accessories. The cable tray can be erected independently in the building or laid on various buildings and pipe gallery brackets. It should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance.

[0003] According to the utility model of the authorization announcement number CN219304400U, a long-span cable bridge is disclosed, including a first bridge, a second bridge cooperating with the first bridge, a hanger arranged for load-bearing traction, a first fixing component for fixing arranged on the hanger and the first bridge, and a second fixing component for fixing arranged on the first bridge and the second bridge. The first bridge includes the first bridge, a first connecting hole arranged on the first bridge, the second bridge is L-shaped, the second bridge includes a second bridge body, and a second connecting hole is arranged on the side of the second bridge body, the second fixing component includes a second nut and a second bolt, the second nut is fixed on the right side wall inside the first bridge and the side wall of the second bridge, and the inner circle of the second nut is aligned with the first connecting hole and the second connecting hole Correspondingly, the first bridge and the second bridge can be fixed and separated by the second fixing component. Although the device makes it easy to separate the second bridge by setting the second fixing component, the first bridge and the second bridge can be easily fixed and separated by the structure of the second fixing component, which can facilitate the maintenance of cables. However, the device is not convenient for adjusting the spacing inside the cable bridge. Since the bridge has a long service life, space needs to be reserved inside for subsequent cables to be placed. The larger space can easily cause the cables to move. After placing multiple cables, the cables are prone to pile up on one side, which can easily cause the center of gravity of the bridge to shift, and it is not convenient to adjust the distance between the bridges, making it less practical. To this end, we provide an adjustable combined large-span cable bridge to solve the above problems. Utility Model Content
