Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cables, in particular to an anti-deformation cable. BACKGROUND

[0002] The armored cable is a cable with superior performance, and the existing armored cable is made in a multi-layer winding manner. The most common way is to use a metal layer to wind multiple cables inside, and then wrap the metal winding layer with a rubber outer layer. This kind of cable is large in size and heavy in weight, and the spiral winding manner, once the torsional force spiral direction is opposite to the winding direction of the metal layer, the actual situation is to loosen the metal layer, and then the stainless steel layer cuts the outer layer. Under pressure, the internal armored layer is also prone to deformation, and it also provides no deformation allowance during pulling. Especially in the process of laying, the armored layer is difficult to handle, and the subsequent connection operation is complicated. SUMMARY

[0003] To solve the above technical problems, the present application provides an anti-deformation cable.

[0004] The technical scheme of the present application is as follows: an anti-deformation cable, comprising a cable core layer wrapping a cable core portion, a strip-shaped armor clamped on the cable core layer in the axial direction, and the number of strip-shaped armors is not less than four, the four strip-shaped armors are axially spaced and clamped with a transition limiting belt at the axial position, and the arc-shaped ends of the transition limiting belt are clamped between the adjacent two strip-shaped armors, there is a gap between the two transition limiting belts, the number of strip-shaped armors and transition limiting belts is equal, and an external protective layer is wrapped on the transition limiting belt. The external protective layer comprises a sheath layer, a capillary hole inside the sheath layer is embedded with an internal and external layered protective net, an annular groove on the periphery of the dividing strip is embedded with a plurality of surrounding upper pressing layers, and an annular groove on the inner periphery of the sheath layer is embedded with a plurality of surrounding lower pressing layers.

[0005] Further, the cable core layer comprises a hard sheath, the surface of the hard sheath is integrally formed with spaced annular fins, and an annular cavity is reserved between adjacent two annular fins.

[0006] The cable core layer is provided, the hard sheath is made of hard rubber, the annular fin is made of elastic rubber ring, and the annular fin is inlaid with the inner wall of the hard sheath and is attached to the surface of the cable core portion. In this way, during stretching, the annular fin can be stretched in the axial direction, and the annular fin can provide elastic compression allowance when pressed.

[0007] Further, the strip armor includes armor plates, the armor plates are shaped as a fan, and the armor plates are provided with perforations at the same height as the positions of the annular flaps. The winding belt is arranged along the perforations on the plurality of armor plates in an S-shaped route, and the winding belt is clamped into the armor plates.

[0008] By arranging a plurality of strip armors on the outer side of the cable core layer in an axial direction, and ensuring that the angles of the extension lines on both sides of the fan-shaped gaps reserved between the strip armors to the axis are within 30°-60°, the purpose of the arrangement is that, when subjected to axial pressure, in the case of 60°, the edges of the two adjacent armor plates close to each other and the line between the two edges of the two armor plates and the points of the outer arc edges and the side edges form an equilateral triangle. At this time, when pressure occurs, a stable state can be formed, which can better support the stress area and prevent the stress area from deforming. Moreover, when arranging the strip armors, it is necessary to note that the number of strip armors is even and symmetrically distributed on the cable core layer, so that the middle layer can be more stably supported. After the armor plates are inserted between the two annular flaps, the bottom is in contact with the hard sheath to complete the operation. During the stretching process, since the winding belt is arranged in an S-shaped route and the winding belt is clamped into the armor plates, the surface of the winding belt is close to the surface of the annular flap, and the outer side of the winding belt is flush with the side edge of the armor plate. During the stretching process, the winding belt can limit the range of axial movement, and the circumferential design can improve the overall toughness. In addition, when twisted, it can provide resistance for overall deformation, and the exposed parts are arranged at intervals on both sides of the armor plate. Since the twisted cable gradually forms a spiral dispersion to the axial sides from the twisting point when the cable deforms, the winding belt can ensure that the overall anti-twist can also help to reset the displacement between the annular flap and the armor plate after twisting. The winding belt can also serve as a depth reference line to determine whether the strip armor manufacturing meets the requirements.

[0009] Further, the transition limiting belt includes an arc-shaped plate, arc-shaped strips are arranged at equal distances on the inner wall of the arc-shaped plate, one end of the arc-shaped strips is located between the two annular flaps and forms a cavity between the two armor plates, arc-shaped reinforcing ribs that contact the two armor plates are arranged between the two arc-shaped strips, and reverse clamping feet that are clamped in the limiting port are arranged on both sides of the arc-shaped reinforcing ribs.

[0010] Further, the protective net includes external ribs and internal ribs, the external ribs and the internal ribs are a plurality of, the plurality of external ribs and the plurality of internal ribs are arranged in a loop in the outer sheath, and the external ribs and the internal ribs are arranged in a wave shape.

[0011] Further, the upper pressing layer includes upper pressing plates and first connecting strips, a plurality of the upper pressing plates are connected by a plurality of first connecting strips arranged in an axial direction, the first connecting strips are the same shape as the external ribs, and have a thinner diameter.

[0012] Further, the lower pressing layers comprise lower pressing plates and second connecting strips, and the plurality of lower pressing plates are connected by the plurality of second connecting strips arranged in the axial direction.

[0013] Further, the plurality of upper pressing layers are arranged in a whole ring outside, and the plurality of lower pressing layers are arranged in a whole ring inside, and the inner whole ring and the outer whole ring are arranged in a staggered manner.

[0014] Further, a demarcation strip is arranged on the sheath layer, and a tear strip is arranged between the plurality of upper pressing layers and the plurality of lower pressing layers.

[0015] The present application has the following beneficial effects: 1. By arranging a plurality of strip armors on the outer side of the cable core sheath and spacing them in the axial direction, a stable state can be formed when pressure occurs, and the stress area can be better supported to prevent deformation of the stress area. After the armor plate is inserted between the two annular wings, the bottom is in contact with the hard sheath to complete the operation. During the stretching process, since the winding belt is arranged in an S-shaped route and the winding belt is clamped into the armor plate, the surface of the winding belt is close to the surface of the annular wing, and the outer side of the winding belt is flush with the side edge of the armor plate. During the stretching process, the winding belt can limit the range of axial movement, and the annular design can improve the overall toughness. In addition, when twisting, it can provide resistance to overall deformation, and the exposed part is arranged between the two sides of the armor plate. Since the cable is twisted, the cable deforms gradually in a spiral shape from the twisting point to the two sides of the axis, so the winding belt can ensure that the overall anti-twist can also help to reset the displacement between the annular wing and the armor plate after twisting. The winding belt can also serve as a depth reference line to determine whether the strip armor manufacturing meets the requirements.

[0016] 2. The benefits of the wave-shaped arrangement of the external and internal reinforcing bars. If straight, parallel external and internal reinforcing bars are used, they have little ductility when subjected to tension, and the cable becomes very rigid. When bending at a small radius, the straight external and internal reinforcing bars on the outside may be "pushed out" or damaged. The curved external and internal reinforcing bars have a slight "straightening" process when subjected to tension. During this process, the external and internal reinforcing bars are not stretched, but provide a certain amount of ductility and buffer for the cable, allowing the tensile structure to be compatible with the bending deformation of the cable.

[0017] 3. The outer and inner ribbing are connected to form a ringed mesh, which forms a stable topological structure. When the cable is subjected to torsion, the mesh resists deformation as a whole. It effectively distributes local stresses over the entire circumference. In a normal non-armoured cable, the inner layers can slide relative to each other when subjected to strong torsion, causing the outer skin to bulge and even tear, forming a "lantern" shape. The outer and inner ribbing mesh layers act like a strong "cage", holding the cable's internal structure tightly together, preventing it from being displaced by torsion.

[0018] 4. The design of the upper press plate. Without the upper press plate, when the cable is subjected to a large tensile force, the ringed outer and inner ribbing have a tendency to be "straightened". During this process, the geometry of the ringed outer and inner ribbing can be distorted unevenly, for example, some meshes are stretched more, and some are compressed. The first connecting strip ringed outer and inner ribbing are firmly fixed on the designed bending radius, ensuring the synchronization and stability of the entire ringed outer and inner ribbing structure during the stretching process.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0022] Referring to Figures 1 to 10 The anti-deformation cable shown in the figure comprises a cable core layer 1 wrapping a cable core portion 2, strip armors 3 clamped on the cable core layer 1 in the axial direction, and the number of the strip armors 3 is not less than four, the four strip armors 3 are axially spaced apart and a transition limiting belt 4 is clamped between the adjacent two strip armors 3, there is a gap between the two transition limiting belts 4, the number of the strip armors 3 is equal to that of the transition limiting belts 4, and an external protective layer is wrapped on the transition limiting belt 4. The external protective layer comprises a sheath layer 5, the capillary holes 52 inside the sheath layer 5 are embedded with the internal and external layered protective nets 7, the annular grooves 53 on the periphery of the boundary strips 6 are embedded with the surrounding multiple upper pressing layers 8, and the annular grooves 53 on the periphery of the boundary strips 6 are embedded with the surrounding multiple lower pressing layers 9.

[0023] The cable core layer 1 comprises a hard sheath 11, the surface of the hard sheath 11 is integrally formed with the spaced apart annular fins 12, and the annular cavities 13 are reserved between the adjacent two annular fins 12.

[0024] The cable core layer 1 is provided, the hard sheath 11 is made of hard rubber, the annular fins 12 are made of elastic rubber rings and arranged on the hard sheath 11, and the annular fins 12 are flush with the inner wall of the hard sheath 11 and attached to the surface of the cable core portion 2, so that the annular fins 12 can be stretched in the axial direction during stretching, and the annular fins 12 can provide elastic compression allowance during pressing.

[0025] The strip armor 3 comprises armor plates 31, the shape of the armor plates 31 is fan-shaped, and the armor plates 31 are provided with perforations at the positions of the equal height of the annular flaps 12, the winding belt 32 is arranged along the perforations on the plurality of armor plates 31 in an S-shaped route, and the winding belt 32 is clamped into the armor plates 31.

[0026] By arranging a plurality of strip armors 3 on the outer side of the cable core 1 and ensuring that the angles of the elongated lines on both sides of the fan-shaped gaps reserved between the strip armors 3 to the axis are within 30°-60°, the purpose of the arrangement is that, when subjected to axial pressure, the line between the point where the two adjacent armor plates 31 approach and the outer arc edge of the two armor plates 31 forms an equilateral triangle, and when pressure occurs, a stable state can be formed, which can better support the stress area and prevent the stress area from deforming. Moreover, when arranging the strip armor 3, it is necessary to note that the number of strip armors 3 is even and symmetrically distributed on the cable core 1, so that the middle layer can be more stably supported. After the armor plates 31 are inserted between the two annular flaps 12 and the bottom is in contact with the hard sheath 11, the operation is completed. During the stretching process, since the winding belt 32 is arranged in an S-shaped route and the winding belt 32 is clamped into the armor plates 31, the surface of the winding belt 32 is close to the surface of the annular flap 12, and the outer side of the winding belt 32 is flush with the side edge of the armor plate 31. During the stretching process, the winding belt 32 can limit the range of axial movement, and the circumferential design can improve the overall toughness. In addition, when twisted, it can provide resistance to overall deformation. Moreover, the exposed parts are arranged at intervals on both sides of the armor plate 31. Since the cable deforms gradually in a spiral and disperses to both sides of the axis when the cable is twisted, the winding belt 32 can ensure that the overall anti-twist is also helpful in resetting the displacement between the annular flap 12 and the armor plate 31 after twisting. The winding belt 32 can also serve as a depth reference line to determine whether the strip armor 3 meets the requirements during manufacturing.

[0027] The transition limiting belt 4 comprises an arc-shaped plate 41, arc-shaped strips 43 are arranged at equal distances on the inner wall of the arc-shaped plate 41, one end of the arc-shaped strips 43 is located between the two annular flaps 12 and forms a cavity between the two armor plates 31, an arc-shaped reinforcing rib 44 is arranged between the two arc-shaped strips 43 and contacts the two armor plates 31, and a reverse buckle foot 45 is arranged on both sides of the arc-shaped reinforcing rib 44 and clamped in the limiting port 33.

[0028] By setting the transition limiting belt 4 between the two axial strip armors 3, the adjacent two strip armors 3 can be limited, and the arc-shaped reinforcing ribs 44 abut between the adjacent two armor plates 31, so that a whole annular ring can be formed, and the problem of uneven force distribution caused by the torsion force on the local part can be offset, so that the torsion force will not be concentrated in one position, and the armor plate 31 can have a certain deformation basis, while the arc-shaped reinforcing ribs 44 are made of hard metal or hard material, and the inverted foot 45 plays a positioning role and can prevent the edge of the arc-shaped plate 41 from wrinkling when it deforms, and the space formed by the arc-shaped strip 43, the annular fin 12 and the armor plate 31 contains gas, so that the arc-shaped plate 41 can play a buffering role when the surface of the arc-shaped plate 41 is under pressure, and the cable will not deform excessively in the direction perpendicular to the pressure during the pressing process, and the silica gel layer 42 is also provided, which can compensate for the change of the transition limiting belt 4 when the cable is axially stretched, and ensure the followability of the transition limiting belt 4 as a whole.

[0029] The setting of the transition limiting belt 4 also has an important role, and the transition limiting belt 4 can be separated from the strip armor 3 as a whole, when connecting the cable, the existing method uses a connecting device to fix the two ends of the two cables to realize conduction, but this method needs to purchase auxiliary parts with high cost, and the installation cost is also increased, while the transition limiting belt 4 is directly separated from the strip armor 3, one end of the cable is reserved with the transition limiting belt 4, and the other end of the cable is reserved with a little more strip armor 3, and the length of the reserved strip armor 3 is kept equal to the length of the reserved transition limiting belt 4, then the transition limiting belt 4 is clamped on the strip armor 3, so that when the two ends of the cable are connected, the quick splicing can be realized, and the outer sheath layer 5 can also be spliced in the above-mentioned manner, and wrapped with electrician tape, or fixed with a hoop, so that the cable is less damaged, the operation is convenient, and the connection position will not cause problems in subsequent use.

[0030] The protective net 7 includes external ribs 71 and internal ribs 72, and the external ribs 71 and the internal ribs 72 are arranged in the outer sheath layer 51 in a plurality of rings, and the external ribs 71 and the internal ribs 72 are arranged in a wave shape.

[0031] This arrangement enhances the performance of the outer sheath layer 5, and when the cable is subjected to axial tension, most of the tension will be borne by the grid of the external ribs 71 and the internal ribs 72. The external ribs 71 and the internal ribs 72 have very high tensile strength, which can effectively prevent the cable from being stretched or even broken.

[0032] The benefits of the wavy arrangement of the outer and inner ribbing 71, 72 are that if straight, parallel outer and inner ribbing 71, 72 is used, they have little ductility when under tension, the cable becomes very stiff, and when bending at a small radius, the straight outer and inner ribbing 71, 72 on the outside can be "pushed out" or damaged. The curved outer and inner ribbing 71, 72, when under tension, has a slight "straightening" process, during which the outer and inner ribbing 71, 72 itself is not stretched, but provides a certain amount of ductility and buffer for the cable, so that the tensile structure can be compatible with the bending deformation of the cable, for example, in high-rise buildings, mines, oil wells, the cable needs to support its own weight. This layer of outer and inner ribbing 71, 72 mesh bears almost all the weight, when threading or pulling the cable in the pipeline, the construction personnel will directly pull the cable, and the outer and inner ribbing 71, 72 layer protects the internal copper core / optical fiber from being affected by tension.

[0033] The plurality of outer and inner ribbing 71, 72 are connected to form a ring-shaped mesh, forming a stable topological structure. When the cable is subjected to torsion, the mesh will resist deformation as a whole. It can effectively disperse local stress to the entire circumference. Ordinary non-armored cables may slide relative to each other when subjected to strong torsion, causing the outer skin to bulge or even tear, forming a "lantern" shape. The outer and inner ribbing 71, 72 mesh layer acts like a strong "cage" that tightly binds the internal structure of the cable together, preventing them from being misaligned due to twisting, for example, when the cable is reeled on a reel, especially at high speed or under uneven force, it is easy to twist, and the moving cable used in port cranes, mine excavators, and other equipment will frequently be subjected to torsion during equipment operation and cable dragging. The above design can provide better protection performance for the entire cable.

[0034] The outer and inner ribbing 71, 72 mesh surrounding the sheath layer 5 is similar to a "ring beam" in mechanics. When subjected to radial pressure from the outside, such as being crushed by a heavy object or being buried in the soil and subjected to soil pressure, this ring structure can evenly distribute the pressure to the entire circumference, avoiding the concentration of pressure on a point and crushing the internal fragile core.

[0035] For impact or extrusion of sharp objects, the hard outer and inner ribbing 71, 72 is the first line of defense. The mesh structure can disperse the energy of point impact to the surrounding mesh area, rather than directly transmitting it to the internal insulation layer and conductor.

[0036] The upper pressing layer 8 includes upper pressing plates 81 and first connecting strips 82, a plurality of upper pressing plates 81 are connected by a plurality of first connecting strips 82 arranged in the axial direction, and the first connecting strips 82 have the same shape as the outer ribbing 71 and a smaller diameter.

[0037] The design of the upper pressing plates 81 ensures that when the cable is subjected to a large tensile force, the encircling outer ribs 71 and inner ribs 72 have a tendency to be "straightened". In this process, the geometry of the encircling outer ribs 71 and inner ribs 72 can be unevenly distorted, for example, some meshes are stretched more, and some are compressed. The first connecting strips 82 encircling the outer ribs 71 and inner ribs 72 are firmly fixed on the designed curved arc, ensuring the synchronization and stability of the entire encircling outer ribs 71 and inner ribs 72 structure during stretching.

[0038] The lower pressing layer 9 includes lower pressing plates 91 and second connecting strips 92, and a plurality of lower pressing plates 91 are connected by a plurality of second connecting strips 92 arranged in the axial direction.

[0039] The design has the same effect as the design of the upper pressing layer 8, which will not be described here.

[0040] The outer whole ring is formed by the encircling arrangement of a plurality of upper pressing plates 81, and the inner whole ring is formed by the encircling arrangement of a plurality of lower pressing plates 91, and the inner whole ring and the outer whole ring are arranged in a staggered manner.

[0041] The sheath layer 5 is provided with a partition strip 6, and a tear strip 10 is arranged between the plurality of upper pressing layers 8 and the plurality of lower pressing layers 9.

[0042] In order to facilitate subsequent wiring, the tear strip 10 connects the upper pressing plates 81 on the upper pressing layer 8 into a whole ring, and also connects a plurality of lower pressing plates 91 into a whole ring. First, the sheath layer 5 can be divided into at least four parts, and then the connected upper pressing layer 8 and lower pressing layer 9 are separated by pulling or cutting according to the position of the tear strip 10. In this way, the cable can be spliced into a whole state during subsequent wrapping.

[0043] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
