A track cable fixing device

Abstract

The invention discloses a rail cable fixing device which comprises steel rail clamps and cable clamps, wherein the steel rail clamps are fixed on the surface on the outer side of the bottom of a steel rail; the cable clamps are arranged on the outer sides of the steel rail clamp attachment surfaces of the steel rail clamps and are used for fixing cables. Hangnails are arranged on the inner side of the steel rail, located at the bottoms of the steel rail clamps, and used for tightly binding the surface of the bottom of the attached steel rail. The rail cable fixing device solves the technical problems in the prior art that objects needing to be positioned cannot be effectively fixed on the condition that the steel rail is not suitable for being fixed by bolts, and the requirement on synchronously mounting one or more than one identical or different objects under the condition of changing attachments cannot be satisfied.

Description

Technical field [0001] The invention relates to a cable fixing device, in particular to a rail cable fixing device applied to the field of rail transit. Background technique [0002] In the field of rail transit technology, railway signal systems such as railway locomotives, subways, high-speed trains, light rails, urban rails, and high-speed rails generally use loop technology to determine the precise parking position of trains on platforms. At the same time, the loop is required to be installed at the middle waist of the track. Because the loop cables are usually relatively long and require more fixed positions, and the way to install holes on the rail is not allowed by the actual situation, it is necessary to study a new track cable fixing device so that the loop cable can be installed and fixed at On the rails. [0003] In the prior art, a sheet metal forming part is generally used to fix the foundation cement surface to solve the problem of installing the mid-waist cable of ...

AI Technical Summary

Problems solved by technology

Fixing the sheet metal forming parts on the foundation cement surface can solve the problem of cable installation in the middle of the fixed track, but it requires that the fixed position of the track relative to the foundation surface is a definite value, and when the movable rail is moving on the switch, the relative value of the track to the foundation surface is an uncertain value , there must be interference between each other when the switch moves

In addition, the height of the foundation ground relative to the bottom surface of the track is high or low, and the specific size will not be as standard as the size of the rail. The height and size of the sheet metal forming parts are not well designed, which affects the normal use of the ring line
