Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to a fireproof cable bridge. Background Art

[0002] Fireproof cable trays usually refer to cable trays that can protect cables from smoke and flames in the event of a fire. This type of fireproof cable tray usually uses special fireproof materials or designs to ensure that the normal operation and safety of the cables can be maintained in the event of a fire.

[0003] For example, Chinese patent: Publication No. CN207603125U discloses a fireproof cable tray, comprising a cover plate and a bottom groove; the cover plate is telescopically mounted on the bottom groove, an upper partition is arranged on the bottom surface of the cover plate near the side walls of the bottom groove, and a lower partition is arranged on the side walls of the bottom groove near the bottom surface, the upper partition limits the fireproof pad to be tightly attached to the side walls of the bottom groove, and the lower partition limits the fireproof pad to be tightly attached to the inner bottom surface of the bottom groove.

[0004] Although the setting of upper and lower partitions allows cable trays made of non-fireproof materials to be easily loaded with fireproof mats and have fireproof properties, thus solving the cost problem of fireproof cable trays for enterprises, when fixing the cable trays, the traditional connection methods are mostly welding or clamping, which have poor firmness. After long-term use, the welding parts will be corroded and rusted, resulting in breakage, which affects the use.

[0005] To this end, we proposed a fire-resistant cable tray. Utility Model Content
