Problems solved by technology

[0002] The cable tray is a rigid structural system with closely connected supporting cables composed of straight sections, bends, components, brackets, hangers, etc. of trays or ladders. It is mainly used for comprehensive wiring such as power supply supporting power transmission and wired telecommunication transmission, laying cables This kind of supporting member is most widely used in the supply department of the store, the power transmission system of centralized power supply and distribution of industrial and mining enterprises, hotels, and comprehensive office facilities, and wired telecommunications; the existing cable bridges are mostly linear, and the shape Relatively single, when the cable needs to change direction, only two straight cables can be connected vertically, the transition is not smooth, and the cable is bent too seriously, often resulting in damage to the bend, affecting normal use, and reducing the service life of the cable. In order to overcome the above defects, those skilled in the art have developed a trough cable tray, which is a fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables and other highly sensitive cables. The control cable of the system, etc., it has a good effect on the shielding interference of the control cable and the protection of the cable in the heavy corrosion environment, so the scope of application is getting wider and wider;
[0003] At present, the design of the cable bridge is unreasonable, the service life is short, the corrosion resistance is low, the strength is low, the wear resistance is poor, the use cost is high, and the construction efficiency is relatively low
