Assembled cable support capable of being bidirectionally adjusted

Abstract

The invention discloses an assembled cable support capable of being bidirectionally adjusted, which comprises embedded parts embedded in the side wall of a cable trench, wherein each embedded part isprovided with an embedded part clamping portion, the embedded parts are connected with an upright column through the embedded part clamping portions, the upright column can move in a reciprocating manner in direction of the embedded part clamping portions of the embedded parts relative to the embedded parts, and the upright column is provided with an upright column clamping portion arranged in thedirection along the upright column. The assembled cable support further comprises supporting arms used for supporting cables, wherein one end of each supporting arm is connected to the upright clamping portion of the upright column, the end, which is connected to the upright column clamping portion, of the supporting arm can move up and down in a reciprocating manner along the upright column clamping portion, the other end of the supporting arm bends upwards and warps up, and the upright column below each supporting arm is provided with a limiting member used for preventing the supporting armfrom moving downwards. According to the invention, fast and convenient installation of the cable support and real two-dimensional random adjustment of the cable support are realized, on-site weldingconstruction is avoided, and the welding quality is ensured. The assembled cable support can set and adjust the cable supporting arms according to actual requirements, and is not limited to the fixityof welding.

Description

technical field [0001] The invention relates to the field of supports in substations and in cable trenches of transmission lines, in particular to a bidirectionally adjustable assembled cable support. Background technique [0002] With the development of my country's economy, society and power grid construction, due to limited land resources in cities and towns, more and more cable trenches are used to lay cables. The cable support is one of the important components in the cable trench. It is mainly used to support the cables in the cable trench and plays an important role in the power system. Usually, the cable support is composed of a column and a number of brackets. The connection between the bracket and the side wall of the cable trench is generally a preset embedded part, and welding is used between the column and the embedded parts. At the same time, each bracket and the column Welding is also used between them, and the construction process of this connection method i...

Problems solved by technology

However, due to the welding method used between the support arm and the column, the distance between the support arms is fixed. Once the cable parameters change in the early and late stages, or the voltage level of the cable in the ditch changes during the renovation project, it is very difficult to adjust the cable distance. It is difficult to adjust the spacing between the support arms and the columns, resulting in the need for overall reconstruction of the cable trench on site

In recent years, the State Grid Corporation of China has required the construction of intelligent and prefabricated substations. The traditional welding construction method takes a long time, and the welding between the column and the embedded parts can only be completed on site. The welding quality cannot be guaranteed, which can no longer meet the current requirements. Therefore, it is very necessary to design a fully assembled cable support with two-way adjustment
