Cable bridge with convenient connection and fireproof function

Abstract

The invention discloses a cable bridge with convenient connection and a fireproof function, and belongs to the technical field of cable bridges. The bridge comprises N + 1 bridge units, each bridge unit comprises a bridge main body and a cover plate, the cover plate of the Nth bridge unit is slidably connected with the bridge main body of the N + 1th bridge unit, and the bridge main body of the Nth bridge unit is slidably connected with the cover plate of the N-1 bridge unit; a fire blocking wall which is perpendicular to the length direction of the bridge frame unit and is provided with a threading hole is inserted into the middle of the bridge frame unit, and an access hole is formed in a bottom plate of the bridge frame unit under the fire blocking wall; a containing cavity is formed inthe top of each bridge unit, through holes used for communicating the containing cavities with inner cavities of the bridge units are formed in the cover plates on the two sides of the fire blockingwall, and hot melt adhesives are arranged in the through holes. According to the cable bridge, the two adjacent bridge units are connected in a sliding mode, so that the whole cable bridge is convenient to mount and dismount quickly, and the fire blocking walls in the inner cavities of the bridge units can effectively prevent fire from flowing.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to a cable bridge with both convenient connection and fire prevention functions. Background technique [0002] Cable tray is a full name of a rigid structural system with close support cables composed of trough-type, tray-type or step-type straight sections, bends, tees, cross components, brackets (arm brackets), hangers, etc. , so as to complete the effect of fixing the cable. [0003] When the cable tray is in use, it is necessary to connect many bridge units in sequence, and the existing connection method is |: a connecting plate 117 is set at the end of the two bridge units 100, and the two ends of the connecting plate 117 are respectively connected to each other by screws 118. The two bridge units 100 are fixedly connected to improve the connection strength of the cable tray. There are three disadvantages in the above connection method: one is that it is not convenient t...
