Abstract

The invention discloses a high-voltage cable support structure for a cable tunnel, comprising a high-voltage cable support structure for laying a straight section of a high-voltage cable tunnel and a high-voltage cable turning structure for laying a turning section of a high-voltage cable tunnel. The high-voltage cable support structure includes the Halfen groove embedded in the tunnel wall and the high-voltage cable support fixed on the Halfen groove; The high-voltage cable bracket fixed on the casing, the casing and the column are provided with a positioning structure that can cooperate with each other to fix the casing and the column. The invention is suitable for fixing and turning brackets of various tunnel shapes, and is suitable for all forms of high-voltage cable clamps, and the cable bracket and turning structure are simple to install and the cable bracket is convenient to produce.

Description

technical field [0001] The invention relates to the technical field of cable laying equipment, in particular to a high-voltage cable support structure for a cable tunnel. Background technique [0002] In the current situation of vigorously promoting the comprehensive pipe gallery, the size and shape of the cable tunnel warehouse are changeable, and the cables need to be kept in a horizontal arrangement. Traditional cable supports need to be processed on site according to the cross-sectional shape of the cable tunnel or individually designed for a single tunnel cross-section. The tunnel bracket processed on site is fixed to the tunnel section by welding, which not only leads to low accuracy of the bracket installed on site, but also damages the galvanized layer of the tunnel during welding. Designing the support separately for a single tunnel section will require a lot of grinding tools, and the cost is high. It is difficult for the cable to turn where it needs to turn, or ...
