Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: due to the different uses of the cables and the different voltages of the cables, when the cables are laid, the vertical distance between layers between two adjacent horizontal supports is different. The vertical support is generally installed on the structure through expansion bolts or positioning pins. When the purpose of the laid cable is changed and the distance between two adjacent horizontal supports needs to be adjusted, the vertical support and the horizontal support must be removed. At the same time, it will cause certain damage to the structure, and it is inconvenient to adjust

Abstract

The invention relates to the technical field of tunnel cable installation, in particular to a power tunnel cable rack. The rack comprises a rack body, the rack body comprises a stand column and a plurality of supporting arms. The multiple supporting arms are evenly arranged on the stand column in the vertical direction. The plurality of supporting arms are horizontally arranged; the rack body further comprises a plurality of adjusting pieces and a plurality of connecting pieces, the adjusting pieces and the connecting pieces are arranged in the stand column in a stacked mode in the vertical direction, at least two adjusting pieces are arranged between every two adjacent connecting pieces, and the supporting arms are rotationally arranged on the connecting pieces and attached to the adjusting pieces close to one side of the stand column. The power tunnel cable rack has the effects of being convenient to operate and simple in construction.

Description

technical field [0001] The present application relates to the field of tunnel cable installation technology, in particular to a power tunnel cable rack. Background technique [0002] At present, cable tunnels and cable trenches are the main channels for urban power supply. Cable supports are fixed on the inner walls of cable tunnels and cable trenches, and cables are laid in cable trenches and tunnels through cable supports. Commonly used cable brackets are assembled brackets, and assembled brackets are also called combined cable brackets. The components of the brackets are produced in the factory according to the requirements that the brackets can be directly installed on site. After the cable structure is completed, before the cable is laid or the cable is laid Cable brackets installed directly on site during the process. [0003] The patent document of the existing notification number CN104485623B discloses a telescopic tunnel cable support, including a support composed ...
