Description

Technical Field

[0001] This utility model relates to the field of robot cable technology, and in particular to a robot cable structure for special working conditions. Background Technology

[0002] Special-condition robot cables are cables specifically designed for robots, enabling them to operate stably in extreme environments such as high mechanical stress, temperature changes, and chemical corrosion.

[0003] Currently, cables consist of one or more insulated cores. The structure of the insulated core is a conductor at the center of the core and a conductor insulation layer wrapped around each conductor. The outermost layer of the cable is the cable sheath. Inside the cable sheath, an oxygen barrier layer is provided to wrap all the insulated cores.

[0004] However, the actual structural stability of the cable is relatively limited, especially in terms of flame retardancy. At the same time, its laying stability is relatively poor, which reduces the service life and safety of the cable. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a robot cable structure for special working conditions. Its advantages are as follows.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A special working condition robot cable structure includes a cable core, a copper wire braided shielding layer fixedly connected to the outer wall of the cable core, an insulation layer fixedly connected to the inner wall of the copper wire braided shielding layer, an inorganic filler material disposed on the outer wall of the insulation layer, a steel wire mesh wound around the outer ring of the inorganic filler material, a flame-retardant mechanism fixedly connected to the outer wall of the steel wire mesh, an aramid fiber braided inner tensile layer fixedly connected to the outer wall of the flame-retardant mechanism, and a water-blocking tape fixedly connected to the outer wall of the aramid fiber braided inner tensile layer.

[0008] Through the above technical solutions: the flame-retardant mechanism can prevent the cable from spontaneously combusting due to high temperatures, thus avoiding impact on the cable's transmission performance; the copper wire braided shielding layer can shield electromagnetic waves, preventing electromagnetic interference from affecting data transmission; the water-blocking tape prevents moisture from entering the cable, giving the cable excellent water-blocking and moisture-proof performance; and the tensile strength mechanism can effectively improve the overall strength of the cable, preventing sagging when the span is too large, avoiding unnecessary economic losses, and meeting the user's needs.

[0009] The present invention is further configured such that a glass fiber woven outer tensile layer is fixedly connected to the outer wall of the water-blocking strip, and a polyurethane sheath is fixedly connected to the outer wall of the glass fiber woven outer tensile layer.

[0010] The above technical solutions address the limitations of existing robot cables in terms of structural stability, particularly in terms of compressive strength, and their relatively poor laying stability. These solutions play a crucial role in improving the applicability of the cables and also provide resistance to oil and chemical corrosion, making them suitable for industrial environments.

[0011] The present invention is further configured such that an anti-ultraviolet coating is fixedly connected to the outer wall of the polyurethane sheath, and the thickness of the anti-ultraviolet coating is 0.5mm-2mm.

[0012] The above technical solutions can improve the cable's UV protection capabilities and prevent sunlight from affecting the cable's lifespan.

[0013] The present invention is further configured such that the flame retardant mechanism includes a halogen-free flame retardant layer, a glass fiber layer and an asbestos mesh layer, wherein the outer wall of the halogen-free flame retardant layer is fixedly connected to the inner wall of the glass fiber layer, and the outer wall of the glass fiber layer is fixedly connected to the inner wall of the asbestos mesh layer.

[0014] The above technical solutions effectively improve the fire resistance of this cable by incorporating an asbestos mesh layer and a fiberglass layer. Simultaneously, the halogen-free flame-retardant layer prevents the generation of halogen elements during combustion, thus avoiding any threat to human health and ensuring the safety of the cable's use.

[0015] The present invention is further configured such that the inner ring of the halogen-free flame retardant layer is fixedly connected to the outer ring of the wire mesh, and the outer ring of the asbestos mesh layer is fixedly connected to the inner ring of the aramid fiber woven inner tensile layer.

[0016] Through the above technical solutions, the cable is fire-resistant, corrosion-resistant, waterproof, compression-resistant, and high-strength, making it suitable for various harsh and complex environments with a high safety factor.

[0017] The present invention is further configured such that the outer end of the inorganic filler material is provided with a groove adapted to the insulating layer, and the three sets of insulating layers do not contact each other.

[0018] Through the above technical solutions, the filler material can further improve its deformation and recovery capabilities, thus better enhancing the product's performance.

[0019] The present invention is further configured such that the cable core is provided in three parts, the cable core is located in the inner cavity of the inorganic filler material, and there is no contact between adjacent cable cores.

[0020] The above technical solutions prevent the cable core from shifting position during deformation, thus effectively preventing adjacent cable cores from touching each other during product deformation and further improving the safety of product use.

[0021] The present invention is further configured such that the number of the cable core, the copper wire braided shielding layer and the insulation layer are the same, and the cable core is located at the center of the inner cavity of the insulation layer.

[0022] Through the above technical solutions, the cable is fire-resistant, waterproof, anti-interference, compression-resistant, high-strength, and wear-resistant, making it suitable for various harsh and complex environments with a high safety factor.

[0023] The beneficial effects of this utility model are as follows:

[0024] The special working condition robot cable structure, by setting an asbestos mesh layer and a glass fiber layer, can effectively improve the fire resistance of the cable. At the same time, the halogen-free flame retardant layer can prevent the generation of halogen elements during the combustion of the cable, thus avoiding the threat to human health and ensuring the safety of the cable in use.

[0025] This special-purpose robot cable structure addresses the limitations of existing robot cables in terms of structural stability, particularly in terms of compressive strength, and relatively poor laying stability, by incorporating an inner tensile layer braided with aramid fibers and an outer tensile layer braided with glass fibers. This significantly improves the cable's applicability. Attached Figure Description

[0031] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0032] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0033] Reference Figure 1-4 A special working condition robot cable structure includes a cable core 1, a copper wire braided shielding layer 2 fixedly connected to the outer wall of the cable core 1, an insulation layer 3 fixedly connected to the inner wall of the copper wire braided shielding layer 2, an inorganic filler material 4 provided on the outer wall of the insulation layer 3, a steel wire mesh 5 wrapped around the outer ring of the inorganic filler material 4, a flame-retardant mechanism 6 fixedly connected to the outer wall of the steel wire mesh 5, an aramid fiber braided inner tensile layer 7 fixedly connected to the outer wall of the flame-retardant mechanism 6, and a water-blocking tape 8 fixedly connected to the outer wall of the aramid fiber braided inner tensile layer 7. The flame-retardant mechanism 6 can prevent the cable from spontaneously combusting due to high temperature, thus affecting the cable transmission effect. The copper wire braided shielding layer 2 can shield electromagnetic waves, preventing the cable from being affected by electromagnetic interference and affecting the data transmission effect. The water-blocking tape 8 prevents moisture from entering the cable. The cable has good water-blocking and moisture-proof performance. The tensile mechanism can effectively improve the overall strength of the cable, prevent it from sagging when the span is too large, avoid unnecessary economic losses, and meet the user's needs.

[0034] Specifically, the outer wall of the water-blocking strip 8 is fixedly connected with a glass fiber braided outer tensile layer 9, and the outer wall of the glass fiber braided outer tensile layer 9 is fixedly connected with a polyurethane sheath 10. This solves the problem that the actual structural stability of existing robot cables is relatively limited, especially in terms of their compressive strength, and their laying stability is relatively poor. This plays a crucial role in improving their applicability. In addition, it is oil-resistant and chemically resistant, making it suitable for industrial environments.

[0035] Specifically, the outer wall of the polyurethane sheath 10 is fixedly connected with an anti-ultraviolet coating 11. The thickness of the anti-ultraviolet coating 11 is 0.5mm-2mm, which can improve the anti-ultraviolet capability of the cable and prevent the phenomenon of sunlight affecting the cable life.

[0036] Specifically, the flame-retardant mechanism 6 includes a halogen-free flame-retardant layer 601, a fiberglass layer 602, and an asbestos mesh layer 603. The outer wall of the halogen-free flame-retardant layer 601 is fixedly connected to the inner wall of the fiberglass layer 602, and the outer wall of the fiberglass layer 602 is fixedly connected to the inner wall of the asbestos mesh layer 603. By providing the asbestos mesh layer 603 and the fiberglass layer 602, the fire resistance of this cable can be effectively improved. At the same time, the halogen-free flame-retardant layer 601 can prevent the generation of halogen elements during the combustion of this cable, thereby threatening human health and ensuring the safety of the cable in use.

[0037] Specifically, the inner ring of the halogen-free flame-retardant layer 601 is fixedly connected to the outer ring of the wire mesh 5, and the outer ring of the asbestos mesh layer 603 is fixedly connected to the inner ring of the aramid fiber braided inner tensile layer 7. The cable is fire-resistant, corrosion-resistant, waterproof, compression-resistant, and high-strength, and can be used in various harsh and complex environments with a high safety factor.

[0038] Specifically, the outer end of the inorganic filler material 4 is provided with a groove that matches the insulating layer 3, and the three sets of insulating layers 3 do not contact each other. The filler material can further improve its deformation and recovery ability, and better improve the product's performance.

[0039] Specifically, there are three cable cores 1. The cable cores 1 are located in the inner cavity of the inorganic filler material 4, and there is no contact between two adjacent cable cores 1. This avoids the position deviation of the cable cores 1 when they are deformed, and thus effectively prevents two adjacent cable cores 1 from touching each other when the product is deformed, thereby further improving the safety of the product.

[0040] Specifically, the number of cable core 1, copper wire braided shielding layer 2 and insulation layer 3 are the same. Cable core 1 is located in the center of the inner cavity of insulation layer 3. The cable is fire-resistant, waterproof, anti-interference, anti-extrusion, high-strength, and wear-resistant, and can be used in various harsh and complex environments with a high safety factor.

[0041] Working Principle: The flame-retardant mechanism 6 prevents the cable from spontaneously combusting due to high temperatures, thus avoiding impact on transmission efficiency. The copper wire braided shielding layer 2 shields electromagnetic waves, preventing electromagnetic interference from affecting data transmission. The water-blocking tape 8 prevents moisture from entering the cable, giving it excellent water-blocking and moisture-proof properties. The aramid fiber braided inner tensile layer 7 and the glass fiber braided outer tensile layer 9 address the limited structural stability of existing robot cables, particularly in terms of compressive strength and laying stability, thus playing a crucial role in improving their applicability. The polyurethane sheath 10 is oil-resistant and chemically resistant, while the UV-resistant coating 11 enhances the cable's UV protection, preventing sunlight from affecting cable lifespan, avoiding unnecessary economic losses, and meeting user requirements.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
