A shield machine high-voltage wear-resistant flat cable and its preparation method

Abstract

The invention discloses a high-voltage wear-resistant flat cable of a shield tunneling machine, and a preparation method thereof. The high-voltage wear-resistant flat cable comprises a carbon fiber thin film, a FEP resin carrier, a plastic strip block, a steel wire, a protective film, a V-shaped plate, a bearing strip plate, a connection block, a hexagonal plastic plate, a fine hole, a coarse hole, a cable, a first steel ring and a second steel ring. According to the high-voltage wear-resistant flat cable provided by the invention, contact area between the cable and a surface of a hard objectis reduced, wear resistance of the surface of the cable is improved, anti-pressure ability of the cable is increased, degree of deformation of the cable under pressure is reduced, the cable is connected through the hexagonal plastic plate, the V-shaped plate and the bearing strip plate, and by extrusion of a FEP resin material, the cable and connection parts are covered completely, moreover, pressure damage to the cable caused by an external force is reduced through bearing and decomposition for the force on the hexagonal plastic plate, the V-shaped plate and the bearing strip plate, a structure of the conventional cable surface is changed, and an effect of the cable suitable for the shield tunneling machine is achieved.

Description

technical field [0001] The invention relates to a flat cable and a preparation method thereof, in particular to a shield machine high-voltage wear-resistant flat cable and a preparation method thereof, belonging to the technical field of cables. Background technique [0002] Shield tunnel boring machine, referred to as shield machine, is a kind of special engineering machinery for tunnel boring. Modern shield tunnel boring machine integrates light, mechanics, electricity, hydraulics, sensing and information technology. It has the functions of excavating and cutting soil, Functions such as conveying soil muck, assembling tunnel lining, and surveying and guiding deviation correction involve multiple disciplines and technologies such as geology, civil engineering, machinery, mechanics, hydraulics, electricity, control, and surveying, and require "tailor-made" design and manufacture according to different geology , Reliability requirements are extremely high, and shield boring m...

AI Technical Summary

Problems solved by technology

[0003] The cables used in the shield machine are prone to friction and wear with hard objects such as sand and stones during moving and pulling, causing the insulation layer to be broken and exposing the cables. There is a hidden danger of electric leakage. Weak enough to cause deformation of the cable body, lacking a corresponding internal structure to enhance its compressive strength
