Abstract

The fireproof cable trough box comprises a shell and a movable door, an opening is formed in the side face of the shell, the upper end or the lower end of the movable door is hinged to the shell, and the movable door is used for covering the opening; the shell comprises a metal shell layer and a fireproof shell layer, the fireproof shell layer is wrapped with the metal shell layer, and the movable door comprises a metal door plate and a fireproof door plate; at least one through hole is formed in the top of the shell and used for heat dissipation and pressure relief during faults. The fireproof groove box not only has fireproof performance, but also has the advantages of lightness and thinness, can solve the problem that normal heat dissipation and fault pressure relief cannot be carried out in a traditional fireproof groove box, and meanwhile, adopts a structure that the side surface is provided with the movable door, can be convenient to install and maintain, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of cable troughs, in particular to a fireproof cable trough box. Background technique [0002] like figure 1 As shown, the existing fireproof trough is usually made of silicate material, which is divided into two parts: the bottom trough and the cover plate. In order to realize the fireproof separation between the cables inside the tank box and the cables on other brackets outside the tank box. On the one hand, the fireproof trough made of silicate material is heavy and heavy, making it inconvenient to manufacture, transport and install; Due to the high force requirements, the bracket needs to be reinforced to increase the project investment; in addition, the traditional fire-proof slot box adopts an overlying cover plate, and the slot box is installed between the two-layer bracket arms with a clearance of only 150mm. The clear distance between the arms 10 is about 20mm, and there is no room for manpower ...
