Description

Technical Field

[0001] The present invention relates to the technical field of cable trays, and specifically relates to a cable tray that can be quickly docked and its installation method. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, cross arms and installation accessories, etc. They can be erected independently or laid on various building and pipe gallery brackets, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. For cable trays installed outdoors on buildings, if they are near the sea or in a corrosion area, the material must have physical properties such as anti-corrosion, moisture resistance, good adhesion, and high impact resistance. Due to changes in environmental temperature, steel cable trays will experience thermal expansion and contraction. The loads on the cable tray are divided into static load, dynamic load and additional load. The static load refers to the types, numbers, and outer diameter weights / unit lengths of each cable laid in the cable tray, and they are listed and counted separately according to different routing of cable laying.

[0003] The splicing and installation between existing cable trays are generally fixed by bolts and nuts, so it is inconvenient to disassemble and install, which directly affects the work efficiency. Summary of the Invention
