Abstract

The invention discloses a high-voltage cable holder structure of a cable tunnel. The high-voltage cable holder structure comprises a high-voltage cable supporting structure used for laying a straight-line segment of the high-voltage cable tunnel and a high-voltage cable turning structure used for laying a turning segment of the high-voltage cable tunnel. The high-voltage cable supporting structurecomprises Halfen slots pre-buried in a tunnel wall and high-voltage cable holders fixed to the Halfen slots. The high-voltage cable holder turning structure comprises stand columns, sleeves which arearranged on the stand columns in a sleeving mode and can rotate relative to the stand columns and high-voltage cable holders fixed to the sleeves, wherein locating structures which can mutually cooperate to fix the sleeves and the stand columns are arranged on the sleeves and the stand columns. The high-voltage cable holder structure is suitable for fixing and turning of holders in various tunnelshapes and adapts to high-voltage cable fixtures, cable holders and turning structures in all forms, installation is simple, and the cable holders are 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 of a cable tunnel and a cable fixing structure thereof. 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...
