Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal shearer cables, in particular to a special winding conductor for a coal shearer cable control core. Background Art
[0002] Coal shearer cables are the main power supply cables for coal shearers and other mining equipment. The quality of coal shearer cables is one of the key supporting components that restrict the production efficiency of coal shearers. During use, coal shearer cables need to move back and forth with the coal shearer. The cables are subjected to severe dragging, bending and twisting, as well as possible impacts from coal blocks or falling rocks. The conductors of the cables are easily broken (especially the control core conductors of the cables), and their service life is short. Users need to frequently replace the cables, resulting in high labor intensity. Reduced production efficiency increases the production costs of coal mines.
[0003] The problem that the core conductor of the control wire of the coal mining machine cable is easy to break, resulting in a short service life of the cable has always been a common problem in the industry. How to overcome the problem of easy breakage of the control wire core of the coal mining machine cable and improve the service life of the cable is a key indicator for judging the performance of the coal mining machine cable.

[0009] Preferably, the tensile elements are bundled into 1.5-2.0 mm ropes in the right direction by a wire bundling machine.
[0010] Preferably, when the shearer cable control wire core specification is 2.5mm 2 When the tinned copper wire or copper wire is twisted in two layers on the tensile element.
[0011] Preferably, when the shearer cable control wire core specification is 4mm2 When the tinned copper wire or copper wire is twisted in three layers on the tensile element.
