Mining cable

Abstract

The invention relates to the field of cables, in particular to a mining cable which comprises a cable conductor, an insulation shielding layer wraps the outer side of the cable conductor, a wrapping layer wraps the outer side of the insulation shielding layer, a filling layer is arranged on the outer side of the cable conductor, a liquid bag is embedded in the filling layer, an inner protection layer wraps the outer side of the filling layer, and the inner protection layer wraps the outer side of the cable conductor. The outer side of the inner protective layer is coated with an armor layer, the outer side of the armor layer is coated with an outer protective layer, an arc-shaped structure is embedded in the outer protective layer, one side of the arc-shaped structure is bonded with an indicating lamp, the other side of the arc-shaped structure is provided with a pressure sensitive element, and the pressure sensitive element is connected with a controller used for displaying pressure signals. The controller is electrically connected with the indicator lamp, a miniature battery is arranged in the indicator lamp, and the miniature battery is electrically connected with the indicator lamp; the cable has the advantages of good compression resistance, high temperature resistance and mechanical damage resistance, so that troubleshooting becomes simpler, and the time cost of accident troubleshooting is saved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a mine cable. Background technique [0002] The cable is usually a rope-like cable formed by twisting several or several groups of conductors (at least two in each group). insulating cover. The cable has the characteristics of internal energization and external insulation; mining cable is the abbreviation of coal mine cable, and all mining cables are flame-retardant cables. Due to the complex operating environment and harsh working conditions of mining cables, the life of the cable is short and easy to appear. Security risks. Most of the mines in daily life are underground mines, which are generally suitable for deposits where the ore body is buried deep and is not suitable for open-pit mining economically and technically. When mining, it is necessary to go deep into the ground through the mine, and at the same time, a large number of mechanical equipment is used to cooperate with mining....

AI Technical Summary

Problems solved by technology

[0004] The above scheme squeezes the airbag through the inner side of the rubber arc-shaped extrusion block to deform the extrusion, thereby reducing the extrusion force on the cable and finally improving the anti-extrusion force of the cable body; this method is cleverly designed and realized The effect is also good, but this solution ignores a problem, how to improve the efficiency of investigation and quickly resume production when the cable is damaged or even broken due to external forces such as gravel and human trampling
