Description

A kind of anti-torsion self-supporting type engineering machinery flexible cable

Technical field

The utility model relates to technical field of electric wires and cables, specially a kind of anti-torsion self-supporting type engineering machinery flexible electrical Cable.

Background technique

With the raising of automation level, the cable in mechanical automation equipment is also increased significantly, such as engineering Mechanical excavator, crane, power lathe and logistics delivery line, the industries such as automated machine assembly line are especially movable Mechanical arm dosage is more.And the cables most of mechanical arm is all common rubber cable at present.Since activity is big, Often bending, the sheath of cable will appear crackle, and internal structure will appear loose or phenomenon of rupture.Twisting property and machinery are strong Spend existing defects.

Summary of the invention

In order to overcome above-mentioned existing product defects, the problem to be solved by the utility model is to provide a kind of anti-torsions certainly Type engineering machinery flexible cable is held, the cable breaking strength and anti-torsion are had excellent performance, energy resistant to hydrolysis, oil-stain-preventing, resistance to cutting Corrosion, highly abrasion-resistant damage, scratching resistance, superior anti-vibration draw properties.In view of its special flexible design, this cable is also suitable For unstressed sustained release, can mandatory guidance the lower installation of left and right noncontinuity movement or fixed lay.

To solve the above-mentioned problems, the technical solution of the utility model is：A kind of novel anti-torsion self-supporting type engineering machine Tool flexible cable includes 6 class copper conductors, and TPE elastomer thermoplastic mixtures insulate, the reinforcing rib that finer wire is twisted, The separation layer that TPV thermoplastic vulcanizates squeezes out, the wrapped belting layer of non-woven fabrics, the enhancement layer of aramid fiber braiding, Yi Jiyong The oversheath that PUR polyurethane squeezes out；The twisted reinforcing rib of the finer wire is located at center, TPV thermoplastic vulcanizates separation layer It extrudes on the outside of reinforcing rib, the insulation of TPE elastomer thermoplastic mixtures is extruded on the outside of the 6 class copper conductor, and respectively to reinforce Muscle and separation layer are that center stranding twists together；The non-woven fabrics belting layer is coated on into cable core exterior side, described by several Aramid fiber enhancement layer made of the braiding of aramid fiber silk is coated on the outside of non-woven fabrics；The PUR urethane jacket layer is extruded in cable Outermost layer.

The conductor meets 6 class conductor as defined in GB/T 3956, using the fine anaerobic bare copper wire multiply of high-flexural strength Fine pith synnema is twisted, and pitch ratio guarantees the stability of conductor structure within 16 times.There is the same of superperformance in conductor When, there is very high flexibility.

The insulation uses TPE elastomer thermoplastic mixtures, which has high insulation resistance, high-mechanical property.

The reinforcing rib is formed using finer wire bundle strand, with superior mechanical load bearing ability, is increased Flexibility, steel wire use zinc-plated mode, and the separation layer uses TPV thermoplastic vulcanizate material, are squeezed using crowded tubular process Out, make to coat between finer wire and TPV thermoplastic vulcanizates rubber it is lax, be conducive to sliding.PV thermoplastic vulcanizates rubber has good Elasticity and compression resistant morphotropism and resistance to environment resistance to ag(e)ing.

The belting layer is wrapped using the non-woven fabrics of 20 specification of 2X0.2 Χ, it is therefore an objective to tighten cable core, be unlikely to loose mistake Position.

The enhancement layer is woven using aramid fiber silk, and braiding layer is uniform, does not allow integral joint, and aramid fiber silk has High intensity, high elastic modulus, toughness, thermal stability etc., wear resistence and resistance load performance are high.

The restrictive coating is squeezed out using PUR urethane jacking, and PUR polyurethane has:High-tensile, high tear Property, anti-notch, wear resistance, resistance to alternating bending, impact resistance, low temperature flexibility, oil resistivity.In addition, being squeezed out using high-temperature fusion, make Oversheath and enhancement layer form composite construction, and adhesion is close, does not separate layering in cable frequently moves.

Following effect can achieve using the utility model：Center uses reinforcing rib, and uses separation layer, guarantees that cable exists Bearing reinforcing rib when longitudinal pulling force, there are sliding plane meetings, and Damage to insulation layer is not present；It is drawn being improved using PUR polyurethane oversheath Intensity and tearing toughness are stretched, on the basis of improving resistance to bend(ing) energy, the machinery of cable sheath is further enhanced by reinforcing rib Intensity and toughness；The cable anti-torsion is had excellent performance, and persistent loop of the design service life greater than 10,000,000 times is bent；With super Strong mechanical load ability to bear, is suitable for adverse weather condition and outdoor use.
