Safety cable bridge

Abstract

The invention discloses a safety cable bridge. The cable bridge comprises a cable bridge body, wherein a sealed mounting cavity is formed in the cable bridge body; two side surfaces of the cable bridge body are respectively provided with a plurality of chutes communicated with the mounting cavity; each sliding groove extends upwards from the bottom. A cable is arranged to pass through the chute onthe cable bridge body. The cables are arranged in the sliding grooves in the two sides and penetrate through the whole installation cavity. One or more partition plates are arranged in the mounting cavity in the width direction of the cable bridge body, each partition plate corresponds to one cable, the tops of the partition plates are fixedly connected with the cable bridge body, the bottoms ofthe partition plates are mobile faces, arc-shaped winding parts are formed on the mobile faces of the bottoms of the partition plates, and the cables are arranged in the arc-shaped winding parts to befixed. According to the cable bridge, the active cables and the passive cables are arranged in an isolated mode, mutual influence between the cables is prevented. Meanwhile, the isolation parts are used for winding protection when accidents happen to the cables, the safety of the cables is further improved, and the safety performance of the cable bridge is improved.

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. After a lo...

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
