In addition, when the cable bridge is maintained and modified at a later stage, part of the structures in the original cable bridge assembly, such as part of the first splicing rod 11, the second splicing rod 12, the supporting rod 20, the connecting structure 30 and the like, can be replaced. When the cable bridge is expanded, a new cable bridge assembly can be added on the original basis, and construction is convenient.
Fig. 13 is a partial structural schematic view of a cable tray according to an embodiment of the present disclosure. The manner of connecting the first splicing bars 11 of two adjacent cable tray assemblies 200 is illustrated in FIG. 13. As shown in fig. 13, the first splicing bars 11 of two adjacent cable trays 200 are connected by a connecting structure 30. The ear plates 32 of the two connecting structures 30 may be hinged by a pin. The second splicing bars 12 of two adjacent cable tray assemblies 200 are connected in the same manner as the first splicing bars 11. This allows turning and width variation of the cable tray by turning the first connecting rod 11 and the second connecting rod 12. As shown in FIG. 12, in the direction indicated by arrow A in FIG. 12, the second cable tray assembly 200 makes a turn in the horizontal direction, the fourth cable tray assembly 200 gradually increases in width, the sixth cable tray assembly 200 gradually decreases in width, the eighth cable tray assembly 200 makes a turn in the vertical direction, gradually increases in height, and the tenth cable tray assembly 200 makes a turn in the vertical direction, gradually decreases in height.
The attitude of the cable tray areas shown in FIG. 12 is merely illustrative, and the attitude of each cable tray assembly 200 may be specifically adjusted according to construction requirements.
The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
