Technical Field
[0001] This utility model relates to the technical field of steel-cored aluminum stranded wire, specifically to an anti-oxidation steel-cored aluminum stranded wire. Background Technology
[0002] With rapid economic development, electricity demand is increasing year by year, placing higher demands on the safety, stability, and efficiency of power transmission lines. Traditional steel stranded wire transmission lines have limitations in terms of weight and corrosion resistance, and cannot meet the needs of long-distance, high-capacity power transmission. Steel-cored aluminum stranded wire, due to its excellent conductivity, high strength, light weight, and good corrosion resistance, is gradually becoming the development trend of power transmission line materials.
[0003] However, in actual use, the steel-cored aluminum stranded wire is prone to curling during use or installation due to its excessive length, which affects its performance. Therefore, we propose an anti-oxidation steel-cored aluminum stranded wire. Utility Model Content
[0004] The purpose of this invention is to provide an anti-oxidation steel-cored aluminum stranded wire to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-oxidation steel-core aluminum stranded wire, comprising a steel core, aluminum strands arranged on the outer side of the steel core, an anti-oxidation sleeve arranged on the outer side of the aluminum strands, a protective rubber sleeve arranged on the outer side of the anti-oxidation sleeve, a protective mechanism arranged inside the protective rubber sleeve, and a promoting mechanism arranged inside the protective rubber sleeve, the protective mechanism comprising:
[0006] An elastic steel sleeve is fixedly installed on the arc surface of the anti-oxidation sleeve. An elastic rib is fixedly installed on the side wall of the elastic steel sleeve, and a tortuous rib is fixedly connected to the end of the elastic rib away from the elastic steel sleeve.
[0007] A protective sleeve is fixedly installed on the side of the elastic steel sleeve away from the elastic ribs. The protective sleeve is fixedly installed on the arc surface of the anti-oxidation sleeve, and a rubber ring is fixedly installed on the arc surface of the protective sleeve. The surface of the rubber ring is provided with a groove.
[0008] Preferably, the promoting mechanism includes a rubber sleeve, which is fixedly installed on the surface of the elastic steel sleeve away from the elastic rib, and a rubber elastic strip is fixedly installed on the surface of the elastic steel sleeve away from the elastic rib.
[0009] Preferably, the rubber elastic strip is composed of a uniform circumferential array of two spiral elastic strips, thereby making the rubber elastic strip more elastic.
[0010] Preferably, the outer diameter of the elastic steel sleeve is fixedly connected to the inner wall of the protective rubber sleeve, and the elastic steel sleeve ensures the supporting effect of the protective rubber sleeve.
[0011] Preferably, the number of elastic ribs is set to several, and the several elastic ribs are fixedly installed in a circumferential array on the side wall of the elastic steel sleeve.
[0012] Preferably, elastic ribs are fixedly installed at both ends of the twisted rib to ensure the twisted rib's resistance to torsion.
[0013] Preferably, the protective sleeve is located at the horizontal center of the twisted rib, and the protective sleeve is fixedly installed on the arc surface of the anti-oxidation sleeve, and the twisting of the twisted rib is restricted by the protective sleeve.
[0014] Compared with the prior art, this utility model provides an anti-oxidation steel-cored aluminum stranded wire, which has the following characteristics:
[0015] Beneficial effects:
[0016] 1. This anti-oxidation steel-cored aluminum stranded wire, through the setting of a protective mechanism, with multiple elastic steel sleeves, protective rubber sleeves, and anti-oxidation sleeves, in an equidistant distribution, can reinforce the assembly and avoid the problem of reduced connection tightness due to excessive wire length. The equidistant combination of the spiral and parallel states of the elastic and tortuous ribs can regionally reinforce the equipment, thereby increasing the torsional resistance of the wire. With the setting of protective sleeves and rubber rings, the deformation of the tortuous ribs is limited, preventing large-scale deformation and preventing wire deformation.
[0017] 2. This anti-oxidation steel-cored aluminum stranded wire, through the setting of a promoting mechanism, the local reinforcement of the wire body by the rubber sleeve, and the setting of the rubber elastic strip, ensures that the wire body has a tensile resistance effect and ensures the overall strength of the wire body.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: an anti-oxidation steel core aluminum stranded wire, including a steel core 1, an aluminum stranded wire 2 disposed on the outside of the steel core 1, an anti-oxidation sleeve 5 disposed on the outside of the aluminum stranded wire 2, a protective rubber sleeve 6 disposed on the outside of the anti-oxidation sleeve 5, a protective mechanism 3 disposed inside the protective rubber sleeve 6, and a promoting mechanism 4 disposed inside the protective rubber sleeve 6. The protective mechanism 3 includes an elastic steel sleeve 301, an elastic rib 302, a twisted rib 303, a protective sleeve 304, a rubber ring 305, and a groove 306.
[0024] In one embodiment of this utility model, an elastic steel sleeve 301 is fixedly installed on the arc surface of an anti-oxidation sleeve 5. An elastic rib 302 is fixedly installed on the side wall of the elastic steel sleeve 301. A twisted rib 303 is fixedly connected to the end of the elastic rib 302 away from the elastic steel sleeve 301. A protective sleeve 304 is fixedly installed on the side surface of the elastic steel sleeve 301 away from the elastic rib 302. A protective sleeve 304 is fixedly installed on the arc surface of the anti-oxidation sleeve 5. A rubber ring 305 is fixedly installed on the arc surface of the protective sleeve 304. A groove 306 is formed on the surface of the rubber ring 305.
[0025] Additionally, the promoting mechanism 4 includes a rubber sleeve 401, which is fixedly installed on the surface of the elastic steel sleeve 301 away from the elastic rib 302. A rubber elastic strip 402 is fixedly installed on the surface of the elastic steel sleeve 301 away from the elastic rib 302. The rubber elastic strip 402 is composed of a uniform circumferential array of two spiral elastic strips, thereby making the rubber elastic strip 402 more elastic.
[0026] In this embodiment of the invention, the outer diameter of the elastic steel sleeve 301 is fixedly connected to the inner wall of the protective rubber sleeve 6, thereby ensuring the supporting effect of the elastic steel sleeve 301 and the protective rubber sleeve 6. A plurality of elastic ribs 302 are arranged in a circumferential array and fixedly installed on the side wall of the elastic steel sleeve 301. Elastic ribs 302 are fixedly installed at both ends of the twisted rib 303 to ensure its resistance to torsion. The protective sleeve 304 is located at the horizontal center of the twisted rib 303 and is fixedly installed on the arc surface of the anti-oxidation sleeve 5, thus limiting the torsion of the twisted rib 303.
[0027] In this invention, when in use, multiple elastic steel sleeves 301, together with protective rubber sleeves 6 and anti-oxidation sleeves 5, are equidistantly distributed to reinforce the assembly and prevent reduced connection tightness due to excessive line length. The equidistant combination of the spiral and parallel states of the elastic ribs 302 and the tortuous ribs 303 can regionally reinforce the equipment, thereby enhancing the torsional resistance of the line. In conjunction with the protective sleeves 304 and rubber rings 305, the deformation of the tortuous ribs 303 is limited, preventing large-scale deformation and thus preventing line deformation.
[0028] Furthermore, the rubber sleeve 401 locally enhances the strength of the thread, and together with the rubber elastic strip 402, it ensures that the thread has a tensile resistance effect and guarantees the overall strength of the thread.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
