A towed twist-resistant metal shielded flexible cable for mining equipment

Abstract

The invention discloses a dragging twist-resistant metallic shield flexible cable for mining equipment. The flexible cable comprises a protective sleeve, a plurality of power wire cores and a plurality of ground wire cores, high-strength fibers and control wire cores, wherein each control wire core comprises a conductor, a high-elasticity rubber insulation layer and a heat-resisting thin slip band layer; the conductor is wrapped with the high-elasticity rubber insulation layer and the heat-resisting thin slip band layer; the high-elasticity rubber insulation layer is located between the conductor and the heat-resisting thin slip band layer; each power wire core comprises a conductor which is wrapped with a heat-resisting semiconductor nylon shield strip layer, an insulation layer and a heat-resisting semiconductor nylon shield strip, metal and fiber fixing weaving layer sequentially from inside to outside; each ground wire core comprises a conductor and a semiconductive elastic rubber layer, and the conductor is wrapped with the semiconductive elastic rubber layer; and outer sides of the plurality of the power wire cores and the plurality of the ground wire cores, the high-strength fibers and the control wire cores are wrapped with the protective sleeve, so that a whole is formed. The dragging twist-resistant metallic shield flexible cable is good in flexibility, tensile resistance and twist resistance and longer in service life.

Description

technical field [0001] The invention relates to a cable, in particular to a towing and twist-resistant metal shielding flexible cable for mining equipment. Background technique [0002] Mining equipment uses a cable with a combination of power core and control core. The control core mainly plays the role of signal monitoring, but the cable is subjected to various mechanical stresses such as frequent bending and stretching during operation. The breakage of the wire core, once the control wire core is broken, will lose the monitoring and protection function, and cause the equipment to stop rotating, seriously affecting the use of the user and causing great losses to the user. However, mining equipment uses a combination of power cores and control cores. The control core of the cable is easy to break and has a short service life, which has always been a problem that plagues the mining industry and the cable industry. Contents of the invention [0003] In order to solve the a...

[0002] Mining equipment uses a cable with a combination of power core and control core. The control core mainly plays the role of signal monitoring, but the cable is subjected to various mechanical stresses such as frequent bending and stretching during operation. If the wire core breaks, once the control wire core breaks, it will lose the monitoring and protection function and cause the equipment to stop rotating, seriously affecting the use of the user and causing great losses to the user

However, mining equipment uses a combination of power cores and control cores. The cable control core is easy to break and has a short service life, which has always been a problem that plagues the mining industry and the cable industry.
