Composite type coal cutter cable with optical fiber and electric signal

Abstract

The invention discloses a composite type coal cutter cable with an optical fiber and an electric signal. The composite type coal cutter cable with the optical fiber and the electric signal comprises a line core, an inner jacket, a steel tape armoring layer and an outer jacket, wherein the inner jacket, the steel tape armoring layer and the outer jacket are wrapped outside the cable core in sequence. The line core comprises a plurality of power line cores and a plurality of control line cores, wherein the power line cores and the control line cores are mutually intertwisted. Each power line core comprises a power line core conductor, a power line insulating layer wrapped outside the power line core conductor, a high-strength wrapping layer and a metallic shield layer. Each control line core sequentially comprises an optical fiber core, an optical fiber protective layer, an elastic metal protective sleeve, an optical fiber insulating layer, a control line core body and a control line insulating layer. The composite type coal cutter cable with the optical fiber and the electric signal is resistant to bending and extrusion, and it is guaranteed that the optical fiber and a control line are not prone to breakage. The composite type coal cutter cable with the optical fiber and the electric signal further has the advantages that cost is low, and a circuit is simple.

Description

technical field [0001] The invention relates to a coal shearer cable, in particular to a composite coal shearer cable with an optical fiber and an electric signal. Background technique [0002] With the continuous deepening of coal mine mining, the amount of gas gushing out continues to increase, and the danger of fire, gas, coal dust and other accidents is also increasing. The monitoring methods of manual inspection in the past are far from meeting the requirements of modern production for the accuracy, timeliness and security of monitoring data. Aiming at the problem that the shearer used in the current coal mine cannot collect the image of the working state of the coal mine and its surrounding environment, gas concentration, temperature, humidity and other data, or it is necessary to lay an optical cable line separately, which is costly and complicated. Insufficient performance requirements of timely control and front-line multi-purpose cannot be realized. From the reas...
