At present, there is no teaching device for the installation of instrument cable trays on the market. During the teaching process, students can only learn through pictures and texts. The installation of instrument cable trays at different positions is a very important knowledge point, which is often used in future work. However, students cannot really understand the method through pictures and words, the teaching effect is not ideal, and teachers have no way to really grasp whether students have learned

Description
technical field [0001] The invention relates to the technical field of instrument installation, in particular to a teaching device for installing instrument cable bridges. Background technique [0002] Instrument cable tray is a general term for a rigid structural system with close-fitting support cables composed of straight sections, bends, components, brackets (arm brackets), hangers, etc. of trays or ladders. It is used in horizontal and vertical wiring systems. the installation channel. The instrument cable tray is a cable laying device that standardizes, serializes and generalizes the laying of wires, cables, and optical cables. Its function is to lay the instrument cables smoothly and provide protection for the cables. [0003] At present, the instrument cable trays produced in our country mainly include the following types: according to the different materials for manufacturing the bridges, the bridges are generally divided into four categories: steel cable trays, fl...
