Special cable for concrete processing machinery

Abstract

The invention relates to a special cable for concrete processing machinery. The special cable comprises a cable core, wherein an outer wall of the cable core is provided with an insulating layer; an outer wall of the insulating layer is provided with a soft filling layer; the soft filling layer adheres to an inner wall of an embedded tube; an outer side of the embedded tube is provided with a fixed tube; a filler is arranged between the fixed tube and the embedded tube; an outer wall of the fixed tube is provided with an anti-static layer; an outer side of the anti-static layer is provided with a waterproof layer; an outer side of the waterproof layer is provided with an anti-expansion buffer layer; a plurality of buffer springs are arranged in an inner cavity of the anti-expansion buffer layer; and an outer side of the anti-expansion buffer layer is provided with a fireproof layer. Through adoption of the special cable, the overall strength of the cable is enhanced; the pressure resistant performance of the cable is enhanced; the overall structure of the cable is prevented from being broken easily by stretching; the phenomenon of circuit break is avoided; the damage resistance and corrosion resistance of a surface layer of the cable are enhanced effectively; the waterproof and fireproof performance is enhanced; damage to the cable caused by static electricity is reduced; and the service time of the cable is prolonged. The special cable is novel in structure, and has high practicability.

Description

technical field [0001] The invention relates to a special cable for concrete processing machinery, which belongs to the field of cable technical equipment. Background technique [0002] After nearly 30 years of development, my country's concrete machinery industry has developed by leaps and bounds. According to the "2013-2017 China Concrete Machinery Industry Production and Marketing Demand and Investment Forecast Analysis Report" data show that in 2009 the industry had a total of 44.173 billion yuan in assets, a year-on-year increase of 3.197 billion %, in 2010, the industry had total assets of 68.473 billion yuan, a year-on-year increase of 55.01%. In the first half of 2010, the sales volume of concrete machinery reached 50.6 billion. It completed the task for the whole year of 2009 in half a year, with a year-on-year increase of 130%, ranking first in the construction machinery industry In the second half of 2010, although the development speed has been slowed down, it is s...

Problems solved by technology

[0003] As the cable is an essential part of the concrete machinery industry, since the concrete structure will cause the surface of the object to lose water after it is adhered to the object, the surface of the object will be subjected to great pressure and tension. The tension and pressure generated by the cables connected to the processing machinery after they adhere to the concrete are likely to cause cracks in the cables, short circuits, and corrosion by the concrete structure, which affects normal use. For this reason, a concrete processing machinery is provided. cable
