Problems solved by technology
[0003] There are still many deficiencies in the existing cable trays when they are in use. The existing cable trays have a low capacity for cable penetration and wiring when they are in use. There are often many kinds of cables laid inside the cable trays. The cables are uniformly installed in the cavity of the bridge frame, causing the cables to be messy and disorderly, and it is difficult to identify and control the cables for different purposes; in addition, various cables are in close contact. When the flow rate is too large and heat is spontaneously ignited or a fire occurs due to the influence of the external environment, the flame will quickly pass between the cables, causing a large number of cables to be burned and causing serious economic losses.

The invention discloses a flame-retardant cable bridge easy for zoning wiring, and belongs to the technical field of cable bridge application, a plurality of cable mounting racks are arranged on a mounting table, and a zoning mounting effect on cables is effectively achieved, so that the cables with different purposes can be identified and controlled. Meanwhile, a cable mounting frame is composed of a double-layer embedded ring and an outer rotating ring which are connected in a sliding mode, after the outer rotating ring slides towards the double-layer embedded ring to be stored, independent overhauling or other operation can be easily conducted on different cables without being affected, and operation is easy, convenient and feasible; a fireproof cover connected with the double-layer embedded rings is further arranged in the mounting table, fire extinguishing powder is stored in the fireproof cover, when abnormal high temperature exists in a certain cable mounting frame or a fire disaster occurs, the fire extinguishing powder overflowing outwards in a high-temperature environment is used for flame retardance and fire extinguishment, meanwhile, the fire extinguishing powder is matched with source extinguishing gas led out outwards, and the flame-retardant effect is further improved.
Description
technical field [0001] The invention relates to the technical field of application of cable bridges, and more specifically relates to a flame-retardant cable bridge that is easy to route in different areas. Background technique [0002] With the rapid development of people's living standards, more and more cable trays are installed in buildings. The main function of cable trays is to connect and route cables to facilitate the routing of electrical devices in buildings. The space occupied by the cables is reduced, and it is convenient for people to splice and manage the cables. [0003] There are still many deficiencies in the existing cable trays when they are in use. The existing cable trays have a low capacity for cable penetration and wiring when they are in use. There are often many kinds of cables laid inside the cable trays. The cables are uniformly installed in the cavity of the bridge frame, causing the cables to be messy and disorderly, and it is difficult to ident...
