Foldable cable support

Abstract

The invention belongs to the field of technical facilities for laying power cables in cable trenches, and relates to a foldable cable support which is installed in a cable trench. The foldable cable support comprises a cable support body, and is characterized in that the cable support body is fixedly provided with connecting rods which are parallel to the wall of cable trench, each connecting rod is connected with the cable supporting rod perpendicular to the wall of the cable trench through a rotating shaft, a limiting block is arranged above the non-cantilever end of each cable supporting rod at one side of the rotating shaft, and the limiting blocks are fixed on the cable support body; and the surface, which is fixed with the wall of the cable trench, of the cable support body is provided with support fixing bolts. The foldable cable support is reasonable in structural design, the original fixed horizontal cable support is designed to be foldable, and the horizontal cable supporting rods can rotate upwards and be retracted until being perpendicular to the ground before cable laying or during cable troubleshooting, thereby expanding the activity space in the cable trench to be maximum extent, and providing convenience for movements of the maintenance personnel in the trench and entrance of maintenance equipment.

Description

technical field [0001] The invention relates to a foldable cable support, which belongs to the field of technical facilities for laying power cables in cable trenches. Background technique [0002] Cable tunnels and cable trenches are the main channels for power supply in cities. For a long time, cable brackets made of angle irons have been used to erect cables. Angle iron brackets are usually made of angle iron profiles connected or spliced ​​by welding or fasteners. The cable bracket should be welded with the embedded part of the trench wall. The welding place is anti-corrosion, the installation is firm, and it is horizontal and vertical. The cable support installed on the object should have the same slope as the cable trench or building. The distance from the uppermost and lowermost layers of the cable support to the top of the trench, the floor or the bottom of the trench, and the ground shall comply with the provisions of the "Code for Construction and Acceptance of C...

AI Technical Summary

Problems solved by technology

[0003] Before the cable is laid, the cable support in the cable trench has been installed and fixed, which makes the remaining space in the narrow cable trench even narrower, which brings obstacles and inconvenience to the further laying of the cable and the movement of personnel in the trench

The problem of the existing cable support increases the technical difficulty of cable laying and unnecessary man-hours; moreover, when emergency repairs of cable faults are carried out in the cable trench, due to space constraints, it is difficult for some troubleshooting equipment to enter the cable trench; The narrow space limits the movement speed of the maintenance personnel in the trench, which prolongs the troubleshooting and repair time of cable faults, thereby prolonging the power transmission time and bringing unnecessary economic losses to power consumers and customers
