A wear-resistant and deformation-resistant mining cable

Abstract

The invention relates to a wear-resistant and anti-deformation mine cable, which includes a protective layer, in which there are several wire cores distributed in a circle around the rotation center of the protective layer, and a fireproof layer is distributed in the protective layer, so that A filling layer that deforms to absorb external extrusion force to protect the wire core is distributed between the fireproof layer and the wire core. The protective layer is covered with a friction layer that prevents frictional damage of the protective layer and absorbs external extrusion force. The present invention prevents the protective layer from being broken due to serious wear and tear through the contact friction between the convex part of the friction layer and the outer wall board, and at the same time, the concave area causes the convex part to deform under the action of external force and absorb the external extrusion force; In the invention, the No. 1 extrusion cavity and the No. 2 extrusion cavity distributed in the filling layer generate deformation and absorb extrusion force, so as to prevent the wire core from being broken due to excessive extrusion force.

Description

technical field [0001] The invention relates to the field of mining cables, in particular to a wear-resistant and deformation-resistant mining cable. Background technique [0002] Fuel, metal materials and rare earth materials needed in high-end equipment industry that are common in daily life are mainly stored underground and need to be mined through the construction of mines; because open-pit mines are extremely rare, most mines need to go deep underground through mines, and the underground mining environment is harsh , requires a lot of lighting, and a lot of mechanical equipment needs power supply in the mine, so the demand for cables is huge; the lights in the mine are dim, workers often step on the cables by mistake, and gravel often falls in the mine, which often leads to damage to the cable protective layer and cable cores. Fracture and difficult troubleshooting will affect underground operations and even endanger the lives of underground workers. Therefore, mining c...

[0002] Fuel, metal materials and rare earth materials needed in high-end equipment industry that are common in daily life are mainly stored underground and need to be mined through the construction of mines; because open-pit mines are extremely rare, most mines need to go deep underground through mines, and the underground mining environment is harsh , requires a lot of lighting, and a lot of mechanical equipment needs power supply in the mine, so the demand for cables is huge; the lights in the mine are dim, workers often step on the cables by mistake, and gravel often falls in the mine, which often leads to damage to the cable protective layer and cable cores. Fractures and difficult troubleshooting will affect underground operations and even endanger the lives of underground workers. Therefore, mining cables that are resistant to wear and deformation are required
