Safety Cable Tray

Abstract

The invention discloses a safety cable bridge, which comprises a main body of the cable bridge. There is a sealed installation cavity inside the main body of the cable bridge. A plurality of chutes communicating with the installation cavity are provided on both sides of the main body of the cable bridge. Each chute Extending upward from the bottom, the cable is set through the chute on the main body of the cable tray. The cable is laid in the chute on both sides and passes through the entire installation cavity. In the installation cavity, more than one partition is arranged along the width direction of the main body of the cable tray. Each partition corresponds to a cable. The top of the partition is fixedly connected to the main body of the cable bridge. The bottom of the partition is the movable surface. The movable surface of the bottom of the partition forms an arc-shaped winding part, and the cables are arranged Fixed in the winding section. The invention isolates the active cables and the passive cables to prevent the mutual influence between the cables, and at the same time uses the spacer as a winding protection for the cables when an accident occurs, further increasing the safety of the cables and improving the safety performance of the cable tray .

Description

technical field [0001] The invention relates to the field of cable laying, in particular to a safe cable bridge. Background technique [0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently or laid on various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized , installed in the open-air bridge outside the building. [0003] At present, it is not recommended to lay active cables and passive cables at the same time for cable trays. If they need to be laid at the same time, partitions need to be installed inside the bridge to separate them. Since the cables are laid in the bridge, it is inconvenient to repair the cables.

Problems solved by technology

[0003] At present, it is not recommended to lay active cables and passive cables at the same time for cable trays. If they need to be laid at the same time, partitions need to be installed inside the bridge to separate them. Since the cables are laid in the bridge, it is inconvenient to repair the cables. After a long time of use, they are prone to aging and occurrence Spontaneous combustion, if the fire source is not extinguished in time after spontaneous combustion, the fire source will quickly spread to the upper ends of other cables, so the current cable tray is less safe to use and cannot make a safe response in the event of an accident
