Description

Resistance to torsion engineering machinery composite rope

Technical field

The utility model is related to the design field of mechanical composite rope.

Background technology

In frequent mobile engineering mechanical device, particularly in lathe and pipeline with mechanical stress, automatic Change the industries such as Automatic manual transmission line, each building block for laying cable therein is constantly in the state of the dynamic motion that circumnutates. During this, cable is typically in free state in towing, and the conductor of cable subjects main mobile tractive force.In movement During, Cable Bending Radius is only several times of itself external diameter.After being moved back and forth at thousands of times, in the state of high speed, high frequency, Common flexible cable copper stranded conductor conductor often occurs to surrender tired, the disconnected core phenomenon of generation, only one or two month service life, and Restrictive coating easily produces cracking frequently with elastomeric material, restrictive coating when frequently reversing.Board industry is rolled in automatic assembly line, metallurgy In, the pliability to mobile frequently flexible cable proposes requirement higher.Due to the damage of cable, whole production line is caused to be stopped The problem of product frequently occurs, and in this class industry, a kind of device of urgency easily loss is belonged to for frequent mobile flexible cable.

Utility model content

The utility model purpose is for problem above, there is provided it is enhanced resistance to that one kind improves life of product, tensile strength Reverse engineering machinery composite rope.

The utility model includes cable core, and general belt layer, total combination belting layer and outer shield are orderly arranged outside each in the cable core Layer；The cable core includes four groups of insulated wire cores of pair twist, and split screen is respectively provided with the outside of the insulated wire cores of the pair twist described in every group Layer is covered, drainage thread is respectively provided between every group of insulated wire cores of pair twist and corresponding sub-shield；Every group of insulated wire of pair twist Core includes two conductors for being enclosed with insulating barrier respectively respectively；Subpackage is orderly arranged outside each in the insulated electric conductor of four strands of pair twists Belt, subassembly belting layer, total screen layer；Some stranded conductors are set in total screen layer periphery, in every stranded conductor Center be respectively provided with reinforcement, stranded conductor insulating barrier is respectively provided with the outside of every stranded conductor.

Advantage of the present utility model is as follows：（1）Dual shield prevents interfering with each other for adjacent quad signal, total shielding Layer not only prevents interference of the external electromagnetic field to cable core, while also have mitigating the effect that external force impacts to internal cable core.（2） Using thin tin plating soft copper silk+high intensity DuPont fibrids and the stranded high-strength combination reinforced core of steel wire.This combination adds Strong core on the premise of ensureing that D.C. resistance meets the requirements of the standard, by the skeleton strengthening action of DuPont fibrids or steel wire, Make up the shortcoming that copper wire is susceptible to fracture in reciprocating motion.When especially cable is in and accelerates or move vertically state, Reinforced combination conductor wire core bears tractive force during motion together with cable core reinforcement.（3）Combination belting layer uses multiple-layer overlapped Wrapped, with characteristics such as high intensity, high elastic modulus, toughness, heat endurances, wear resistence and resistance load performance reach and gather with pure Fat is the same.（4）Insulating materials is made up of thermoplastic elastomer (TPE), has preferable abrasion resistance properties, higher after insulation processing Elongation at break and tensile strength higher.Jacket material is using green safety, recyclable reusable a new generation's elasticity Body material --- Halogen thermoplastic elastomer (TPE), it has oil resistant, chemically-resistant solvent, high resiliency, wear-resisting, high-low temperature resistant, resistance to water enchroachment (invasion) Erosion, the leaching of resistance to environment are damaged in one, it is ensured that stability of the cable in various special adverse circumstances.（5）This cable is due to combination The strengthening action of conductor thread core, cable core reinforcement and combination belting layer, the tensile strength of cable is greatly enhanced, can be than general Flexible cable bears bigger speed, is more suitable for being used in towing.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

As shown in figure 1, the utility model includes cable core, general belt layer 1 is orderly arranged outside each in cable core, always combines belting layer 2 and outer jacket 3；Cable core includes four groups of insulated electric conductors 4 of pair twist, and split screen is respectively provided with every group of outside of the insulated electric conductor of pair twist 4 Layer 5 is covered, drainage thread 6 is respectively provided between every group of insulated electric conductor of pair twist 4 and corresponding sub-shield 5；Every group of pair twist it is exhausted Edge core 4 includes two conductors 14 for being enclosed with insulating barrier 13 respectively respectively；Set successively in four bursts of outsides of the insulated electric conductor of pair twist 4 Put subpackage belt 7, subassembly belting layer 8, total screen layer 9；Some stranded conductors 10 are set in the periphery of total screen layer 9, at every The center of stranded conductor 10 is respectively provided with reinforcement 11, and stranded conductor insulating barrier is respectively provided with the outside of every stranded conductor 10 12。
