Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a bracket for a cable bridge. Background Art

[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks. The national standard "Common Terminology of Urban Public Transportation" defines urban rail transit as a general term for fast, large-capacity public transportation that is usually powered by electricity and adopts a wheel-rail operation mode. When rail transit is in operation, the cables need to be guided to prevent interference with vehicle travel.

[0003] At present, when guiding the cables on both sides of the track, since the cables are installed above the track, it is easy to cause overlapping interference between the cables when the vehicle is too high. At present, when the cables are moved, the docking points of the cables are mostly fixed connections. When the moving distance is large, a large pulling force will be generated at the docking point, thereby damaging the cable. Utility Model Content
