A production method of comprehensive flat cable for coal shearer

Abstract

The invention discloses a comprehensive flat cable production method for a coal mining machine and relates to the technical field of manufacturing of cables of a coal mining machine. The method is characterized in that a control line, a power line and a water pipe are arranged in parallel, the water pipe keeps a distance away from the power line, and the control line is composed of a communication cable and control cables arranged around the communication cable. The method specifically comprises the following steps: 1, manufacturing the control line, the power line and the water pipe; 2, extruding an inner sheath at the periphery of the control line and the power line, which are arranged in parallel; 3, weaving and winding dipped fibers around the inner sheath and the water pipe; 4, wrapping the dipped fibers with an outer sheath. The method has the advantages that the power line, the control line (communication cable) and the water pipe are combined together and arranged in parallel and the sheaths are extruded to form a flat cable, the flat cable is thinner, and the bending radius of the cable is less than 3 times as large as the diameter of the cable; the core of the power line adopts the structure that a plurality of tinned copper wires are twisted, and a tensile filament is added among the tinned copper wires, so that the overall tensile resistance of the cable can be improved.

Description

technical field [0001] The invention relates to a coal shearer cable, in particular to a production method for a coal shearer comprehensive flat cable. Background technique [0002] The coal shearer is a large-scale equipment integrating machinery, electricity, and hydraulic pressure. During the coal cutting work of the coal shearer, the electrical machinery needs to be cooled by water, and it also needs to be sprayed to reduce dust on the coal mining face. Cable power supply, water pipe cooling electrical machinery, spray dust, However, the cable and the water pipe are used separately and in parallel. When installing and laying, the cable and the water pipe need to be placed in the tow cable clamp respectively, which is laborious and laborious; It does not have the function of transmitting communication signals. During operation, due to various mechanical stresses such as frequent bending and stretching, the control wire core is broken and pulled off, especially in thin and...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the mining height of the thin coal seam working face is low, and the wire core of the shearer cable is easily broken and pulled after being mechanically bent, the invention provides a production method for the comprehensive flat cable of the shearer, which produces The bending radius of the cable is less than 3 times the diameter of the cable, which is extremely flexible and suitable for coal mining with low coal seam shearers
