Super-high-fire-resistant glass steel cable trough box for tunnel

Abstract

The invention, which relates to the technical field of cable trough boxes, discloses a super-high-fire-resistant glass steel cable trough box for a tunnel. The glass steel cable trough box comprises abox body. Horizontal plates are fixedly connected to the left and right sides of the inner wall of the box body; first chutes are formed in the lower surfaces of the horizontal plates; and first sliding blocks are connected in the first chutes in a sliding manner. Vertical plates are fixedly connected to the lower surfaces of the first sliding blocks and are in overlap joint relationship with thelower surface of the inner wall of the box body. Two thermal-conductive pads are fixedly connected to the lower surface of the inner wall of the box body. According to the super-high-fire-resistant glass steel cable trough box, with a first clamp hole, a first clamp groove, the first sliding block, second sliding blocks, and second chutes, the worker can install the box body conveniently to avoidmulti-person mounting work; the box bodies are connected and fixed by means of clamping instead of bolt fixation; the horizontal and vertical plates inside the box body are used for separation and storage of different cables, so that the worker carries out cable burying conveniently and the usage need is met.

Description

technical field [0001] The invention relates to the technical field of cable troughs, in particular to a super-strength fire-resistant FRP cable trough for tunnels. Background technique [0002] The cable trough box is a kind of cable tray, which is installed on the pre-installed bracket, which is equivalent to an overhead cable trench. The metal cable trough box with cover also has the function of electromagnetic shielding, which can prevent the expansion of cable accidents. [0003] FRP cable troughs are generally made of one-piece pressing. During installation, multiple people are required to cooperate and support the overall hoisting and installation, which wastes the physical strength of the staff. Moreover, the internal structure of the trough box is simple, which cannot satisfy the effect of separating and placing cables. , cannot well meet the needs of use.

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a super-strong refractory FRP cable trough box for tunnels, which solves the problem that FRP cable trough boxes are generally pressed together, and many people are required to cooperate and support the whole for hoisting and installation during installation. It wastes the physical strength of the staff, and the internal structure of the slot box is simple, which cannot meet the effect of separating and placing the cables well, and cannot well meet the needs of use
