Abstract
The utility model provides a coal mining machine flexible cable with a metallic shielding rubber sleeve, which comprises a cable core and an outer sheath. The cable core includes a central grounding wire core conductor, three peripheral power wire cores and a control wire core bundle, each power wire core is sequentially provided with a power wire core conductor, an insulating layer and an insulating shielding layer from inside to outside, the control wire core bundle consists of three control wire cores, and each control wire core is sequentially provided with a control wire core conductor and an insulating layer from inside to outside. Compared with a common mine electric cable, the flexible cable is more effectively resistant to smashing, squeezing, impact, scratching, friction and other mechanical force action, guarantees safety utilization of the electric cable in a coal mine, eliminates hidden safety hazards to operation of the coal mine brought by the electric cable, and is suitable for popularization and utilization in coal mines.
Description
Technical field
The utility model belongs to the cables manufacturing technical field, is specifically related to a kind of coal-winning machine metallic shield rubber sleeve flexible cable.
Background technology
Coal is the first energy of China, and it is the first that output occupies the whole world.Along with coal industry is integrated continuing to increase of reorganization dynamics, the mechanization degree of coal enterprise is more and more high, coal industry also constantly increases the demand of various mining Plastic-sheathed Cables, in order to ensure coal mining safety, is had higher requirement with the security reliability of cable in the colliery.Because coal-winning machine can suffer pounding pressure, pushing, impact, scratch, rub and other mechanical force of coal cinder often with cable under mine; add the influence of underground wet environment; the sheath rubber on common cable surface is because tensile strength and tearing toughness are poor; very easily damage and lose the effect of protecting cable, bury potential safety hazard to the operation of coal industry.And electric cable for coal mining machine belongs to mobile flexible cable, and its resistance to bend(ing) can be had relatively high expectations, and therefore needs the good coal-winning machine cable of a kind of resistance to bend(ing) energy of exploitation.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of resistance to bend(ing) energy the good metallic shield rubber sleeve flexible cable that is used for coal-winning machine.
The utility model is achieved through the following technical solutions:
Coal-winning machine metallic shield rubber sleeve flexible cable is made up of cable core and oversheath, and described cable core comprises the earth connection core conductor of central authorities, all around three strands of power cores and one control core bundle; Described power core is followed successively by power line core conductor, insulating barrier and insulation screen from the inside to the outside; Described control core Shu Yousan thigh control core is formed, and per share control core is followed successively by control line core conductor, insulating barrier from the inside to the outside.
Preferably, the annealed copper wire of described power line core conductor after with the oxygen-free copper bar wire drawing carries out zinc-plated processing, carries out compound bundle strand again, and twisting pitch is than less than 10 times;
Preferably, described insulation screen adopts zinc-plated soft copper silk to add dacron thread and weaves, and density reaches more than 80%;
Preferably, will control earlier core stranded after, together stranded with the main insulation core again, described control line core conductor twisting pitch is than less than 12 times.
Advantage of the present utility model is:
The utility model has increased insulation screen outside the insulating barrier of power core, adopting zinc-plated soft copper silk to add dacron thread weaves, the cable resistance to bend(ing) can be improved greatly, and more anti-ly pound pressure, push, impact, scratch, rub and other mechanical force, ensure the safe handling of cable in the colliery, eliminated the potential safety hazard that cable brings for the coal operation.
