Description
Technical Field
The utility model relates to a wire and cable technical field specifically is a control wire conductor for high strength coal-winning machine cable.
Background
Along with the development of economy, the energy demand of China is more and more, and the government guides the policy in the aspect of energy industry price control, so that the importance of coal in the energy structure of China is highlighted, and the development of coal mining industry is accelerated. In fact, in addition to the coal mining industry itself, the equipment manufacturing industry for matching with the coal mining industry is also developing at a rapid pace, and therefore, technical innovation for accelerating the coal mine equipment manufacturing industry is imminent.
The control wire core in the coal mining machine cable matched with the coal mining machine at present has the problems of easy core breakage and short service life, which seriously influences the production efficiency of the coal mining machine. Through field observation of the use environment and the use method of the cable of the coal mining machine, the fact that the local bending radius of the cable is far smaller than the cable bending radius specified by the standard in the use process is found, the cable is frequently subjected to combined actions of over-bending, stretching, mechanical external force impact and the like for a long time, and the section of the conductor of the control wire core is far smaller than that of the conductor of the power wire core, so that the control wire core of the cable of the coal mining machine is very easy to break.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a control line conductor for high strength coal-winning machine cable, through increase twisting fiber core in the conductor, improved the compliance and the tensile strength of conductor, reduced the emergence of the disconnected core condition of control line conductor in the use, prolonged the life of cable, improved the production efficiency of coal-winning machine.
In order to achieve the purpose of the invention, the utility model adopts the following technical scheme: the control line conductor for the high-strength coal mining machine cable comprises a lead and a twisted fiber core, wherein the lead is provided with a plurality of strands, the twisted fiber core is provided with a plurality of strands, the plurality of strands of twisted fiber cores are uniformly distributed among the plurality of strands of leads in the circumferential direction, the lead and the twisted fiber cores are mutually bundled to form a conductor, the strand pitch diameter ratio of the conductor is 8-16, and the outer diameter of the lead is the same as that of the twisted fiber core.
Preferably, the ratio of the tensile strength of the twisted fiber core to the cross-sectional area of the twisted fiber core is 1900N/mm2。

Reference numerals: 1. a wire; 2. twisting the fiber core.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the structure of the control wire conductor for the high-strength cable of the coal mining machine includes a wire 1 and a twisted fiber core 2, the wire 1 is provided with a plurality of strands, the twisted fiber core 2 is provided with a plurality of strands, the twisted fiber cores 2 are uniformly distributed between the strands of wires 1 in the circumferential direction, so that the wire 1 in the conductor is uniformly stressed, the excellent bending performance of the conductor is ensured, and the tensile strength of the fiber material is high and the tensile rate is low.
The conducting wire 1 and the twisted fiber wire core 2 are mutually bundled to form a conductor, the bunching pitch diameter ratio of the conductor is 8-16, and the outer diameter of the conducting wire 1 is the same as that of the twisted fiber wire core 2. The cross-sectional area of the twisted fiber core 2 has a certain proportional relationship with the tensile strength, in this embodiment, the ratio of the tensile strength to the cross-sectional area of the twisted fiber core 2 is 1900N/mm2. The wire 1 adopts a single wire, and the single wire adopts copper or plated copper material.
In the present embodiment, the single wire is made of a metal-plated copper material, and the twisted fiber core 2 is made of a high-strength fiber. The tensile strength of the copper conductor is lower than that of the fiber material, the tensile rate of the copper conductor is greater than that of the fiber material, most of acting force acts on the fiber wire core when the conductor is subjected to tensile force, the force applied to the copper conductor is reduced, and the possibility that the control wire conductor is broken by pulling is reduced. Wire 1 is equipped with 16 strands, and twisting fiber core 2 is equipped with 3 strands, and three strands of twisting fiber core 2 and three strands of wires 1 in addition wind the back of evenly arranging of one of them wire 1 circumference, outside twisting fiber core 2 and wire 1 that evenly arrange in circumference, the round wire 1 of evenly arranging in circumference forms the conductor.
The above is the preferred embodiment of the present invention, and a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as the protection scope of the present invention.
