Therefore, the cable for the driving controller has higher performance requirements on tensile strength, deflection resistance and the like. To improve these properties of control cables, the prior art has also explored, for example:

The cable is characterized in that an aramid rope with a tensile effect and a wire core are twisted together to be used as a cable core. The aramid fiber used in the cable is too much, the aramid fiber is high in price, the cost of the cable is increased, the strength of the aramid fiber is high, and the cable is easy to damage a wire core when being bent.
The utility model provides a "novel anti-interference tensile wear-resisting control cable" of bulletin number CN215730944U, it includes the protective sheath and sets up a plurality of sinle silk in the protective sheath inside, and the space between the sinle silk adopts tensile to fill the rope and fills, and the protective sheath is including setting up at the nylon sheath of outermost and setting up at the inboard combination shielding layer of nylon sheath, and the combination shielding layer includes tinned copper wire and weaves with aramid yarn. The cable is characterized in that a tensile filling rope is used as filling in a cable core. Notably, the aramid yarn weave in the combined shield is flexible because it is a low density weave structure, which does not have a positive effect on the tensile properties of the cable. The cable also uses a large amount of aramid fibers, so that the cost of the cable is increased, and the weaving processing time is longer.
The control shielding cable for the garbage crane comprises a cable core, an aramid yarn woven reinforcing sleeve, a polyurethane inner sheath, a woven shielding layer and a polyurethane outer sheath, wherein the cable core comprises a central tensile element and a plurality of control wire cores, the plurality of control wire cores are wound on the central tensile element side by side, and the central tensile element is used for dispersing the tensile force of the control wire cores. The central bearing element is composed of a plurality of helically stranded aramid filaments, an outer aramid filament braid and an outer thermoplastic elastomer jacket. The cable is characterized in that a central tensile element is used for providing tensile property, and a wire core is wound outside the central tensile element. The cable has similar problems to the novel anti-interference, tensile and wear-resistant control cable.
The control cable comprises a control cable core conductor, aramid fiber tensile pieces, an insulating layer, glass fiber belts, polytetrafluoroethylene belts, a central reinforcing piece and filling materials, wherein the control cable core conductor is provided with a plurality of the aramid fiber tensile pieces and is arranged around the central reinforcing piece, the outside of the control cable core conductor is wrapped with the insulating layer, the outside of the insulating layer of the control cable core conductor is wrapped with the glass fiber belts, the filling materials are arranged at gaps between the inner sides of the glass fiber belts and the outer sides of the insulating layer, and the outer sides of the glass fiber belts are wrapped with the polytetrafluoroethylene belts.

In summary, a cable with high tensile property is needed, so that the cable sheath can be prevented from cracking under the condition of multiple use, and the service life of the cable can be prolonged.
Disclosure of Invention
In order to solve the problems in the prior art, improve the tensile property of the cable, prevent the sheath from cracking and prolong the service life of the cable under the condition of ensuring that the sheath of the cable can be used for multiple times, the utility model provides the cable for the tensile travelling crane controller. The method comprises the following steps:
The cable for the tensile travelling crane controller is structurally characterized in that a first wrapping layer 4, a shielding layer 5, a second wrapping layer 6 and an outer sheath 7 are sequentially wrapped outside a cable core 1 formed by twisting a plurality of wire cores 11, wherein a filling layer 3 is arranged between each wire core 11 in the first wrapping layer 4;
The outer diameter of the cable ranges from 19.0mm to 27.0mm, and the cross-sectional area of the conductor 111 is 1.0mm 2～1.5mm2;
the wire core 11 is formed by wrapping an insulating layer 112 outside a conductor 111;
The conductor 111 is formed by twisting tin-plated copper monofilaments with the diameter of 0.193-0.243 mm, the twisting pitch diameter ratio range of the tin-plated copper monofilaments is 16-25 times, and the twisting direction is left;
The insulating layer 112 is made of low-smoke halogen-free flame-retardant ethylene propylene rubber insulating material, and the thickness range of the insulating layer 112 is 1.0 mm-1.2 mm;
The first wrapping layer 4 and the second wrapping layer 6 are formed by overlapping and wrapping non-woven fabrics, the width of the non-woven fabrics is 35-50 mm, and the wrapping covering rate is not less than 20%;
The shielding layer 5 is formed by knitting tinned copper wires, and knitting parameters comprise the nominal diameter of the knitting wires of 0.15-0.25 mm, the knitting density of not less than 80%, the knitting angle of 30-40 degrees and the knitting pitch of 35-45 mm.
The outer sheath 7 is a thermosetting low-smoke halogen-free flame-retardant sheath material, and the thickness range of the outer sheath 7 is 1.43 mm-1.8 mm;
An anti-pulling rope is clamped between the shielding layer 5 and the second wrapping layer 6, and the axis of the anti-pulling rope is parallel to the axis of the cable.
The tensile rope of this cable is located cable core avris, and has only one, has strengthened the tensile ability of cable. Meanwhile, the anti-pulling rope is positioned between the tinned copper wire weaving layer and the non-woven fabric of the second wrapping layer, so that the situation that the anti-pulling rope is directly bonded with the outer sheath to cause the breakage of the outer sheath due to the negative influence of the anti-pulling rope on the outer sheath is avoided. In addition, the tinned copper wire braiding layer plays a shielding role, is made of metal, has high strength, can avoid the contact between the tensile rope and the structure on the inner side of the tensile rope, and prevents the negative influence of the tensile rope on other structures of the cable.
In conclusion, the tensile rope positioned at the side of the cable core enhances the tensile capacity of the cable and avoids the breakage of the outer sheath of the cable.
Because the cable is used for the travelling crane controller, the flexibility of the cable has higher requirements, and for this purpose, specific conductor monofilaments and the twisting structure thereof are designed, so that the conductor becomes a flexible flex-resistant tin-copper plated conductor, the flexibility of the cable is fundamentally improved, the cable has excellent bending radius, and the cable can be ensured to be quickly restored in the daily use process.
The low-smoke halogen-free flame-retardant ethylene propylene rubber insulating material with specific thickness has plasticity superior to that of most plastic materials, and can ensure that the insulating layer can be quickly restored after being bent.
Because the conductor of the cable for the controller transmits weak signals, the electromagnetic shielding performance of the cable is high, and particularly the electromagnetic environment of driving operation is complex, and a shielding layer is designed for the electromagnetic shielding performance. In the cable structure, the copper wire braid or the copper strip can form a shielding layer, and the copper wire braid is softer than the copper strip. In the present cable, specific braiding parameters are designed. The structure of the shielding layer, such as the wire diameter, the braiding density, the braiding angle and the like, also can influence the flexibility and the tensile property of the cable, and the specific shielding layer structure of the cable is matched with other structures of the cable, so that the negative influence on the flexibility of the cable is minimized, and the positive influence on the tensile property of the cable is fully enhanced.
In the outer sheath structure, the elongation of the sheath made of the thermosetting low-smoke halogen-free flame-retardant sheath material is more excellent than that of the thermoplastic sheath, and the sheath is less prone to fracture under the condition of the same tensile force.
Further, the anti-pulling rope is made of aramid fiber.
The aramid fiber has higher strength, and the aramid fiber is light in weight and has negligible structural size, and the tensile strength of the cable is ensured on the premise of hardly influencing the appearance and the weight of the cable.
The preferred number of the wire cores 11 is 7-19, and the sectional area of the conductor 111 is 1.0mm 2～1.5mm2;
Preferably, the packing layer 3 is made of a dust-free rock wool material.
The compatibility of the dust-free rock cotton rope and the ethylene propylene rubber insulating material is good, so that the cable is ensured to be full in roundness, and the situation that the cable is loose after being bent for a long time and the stress on the sheath is increased due to the fact that the twisted wire core is loose is avoided.
Preferably, the range of the twisting pitch diameter ratio of the tinned copper monofilament of the conductor is 20-25 times.
The structure further optimizes the flexibility of the cable, and the larger pitch diameter ratio not only increases the flexibility after twisting, but also reduces the acting force between monofilaments, thereby reducing the damage of stress generated after bending the conductor to insulation.
Preferably, the thickness of the nonwoven fabrics of the first wrapping layer 4 and the second wrapping layer 6 is 0.1mm.
Because the non-woven fabrics are non-hygroscopic wrapping tape materials, the cable can be ensured not to be reduced in shielding performance due to the fact that the first wrapping layer and the second wrapping layer absorb moisture. Meanwhile, the non-woven fabric with the thickness, the width and the covering rate has enough strength to wrap the inner structure of the non-woven fabric, and the thickness of the layer structure is reduced.
In summary, the beneficial technical effects of the cable with the structure include:
1. The control cable has better tensile capacity, and the cable structure also improves and even avoids the outer sheath cracking after multiple uses, so that the insulation is exposed, and the service life of the cable is shortened.
The control cable has a soft flex-resistant tin-copper plated conductor, the flexibility of the cable is improved, the control cable has an excellent bending radius, and the cable can be quickly restored in the daily use process;
2. The larger pitch diameter ratio of the conductor not only increases the flexibility after twisting, but also reduces the acting force between monofilaments, thereby reducing the damage of stress generated after bending the conductor to insulation;
3. The shielding layer structure formed by braiding the tinned copper wires can increase the flexibility of the cable and can increase the tensile property of the cable.
