Combined trench cable support

Abstract

The invention relates to a combined trench cable support. The combined trench cable support is characterized by comprising a support body and a top clamping block, wherein a pair of hook guiding rails perpendicular in direction are arranged at the top of the support body; the two ends of the top clamping block are connected with the top ends of the two hook guiding rails; the outer side faces at the two ends of the top clamping block and the outer side faces of the hook guiding rails are each provided an anti-pulling inverted clamp; a plurality of cable hook modules are arranged on the hook guiding rails in a sleeving mode; anti-tilting clamping blocks are arranged on the upper portion and the lower portion of each cable hook module; a fireproof partition plate is arranged between the top clamping block and the support body. The combined trench cable support has the advantages that the cable support is of a frame structure, stressing is stable and reliable, joints are not prone to fracture, and therefore the service life is long, and the maintenance amount is small; in addition, by the adoption of the anti-pulling inverted clamps, the top clamping block and the support body are prevented from being pulled out easily, the antitheft performance is good, the application range is wide, the combined trench cable support can be applied to various tunnels, coal mines, roadways and drainage ditches, and erecting requirements of ground cables are met.

Description

technical field [0001] The invention relates to a cable support, in particular to a combined trench cable support. Background technique [0002] With the rapid development of my country's economy, the demand for power supply security and communication is also increasing. Modern cables for power supply and communication are generally erected through trenches and tunnels, and as we all know, cable brackets are usually required when erecting cables to avoid electric leakage caused by placing cables directly in trenches or even wet places such as the ground and accelerated aging. [0003] The traditional trench cable supports are all horizontal T-shaped structures, which are specifically composed of several support plates extending horizontally or obliquely upwards connected to the side walls of the columns. The columns are used to connect and fix the side walls of the trench, and the support plates It is used to support the cable. This kind of structure has the following pro...

AI Technical Summary

Problems solved by technology

This kind of structure has the following problems: (1) Due to the limitation of the connection structure between the column and the support plate, the single point is stressed, and its structural strength is weak, and in order to accommodate more cables, the length of the support plate is longer, and the connection between the support plate and the column (2) It is inconvenient to install when the column needs to be connected and fixed with the side wall of the groove by expansion bolts, and the installation efficiency is low; (3) The column and the supporting plate are generally connected by a detachable structure, although it is easy to disassemble and installation, but since only the uprights are connected and fixed with the grooves, the pallet can be lifted directly upwards, because there is a potential safety hazard that is easy to be stolen
