Description

Technical Field

[0001] The utility model relates to a cable with a lightweight armored structure. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or several groups of wires. Many existing cables usually use steel belts or steel wires to form an armor layer to protect the cable from damage and destruction by external mechanical forces. However, the armor layer of the cable is usually mostly metal structure, and the overall weight is relatively large. When the cable is hoisted at high altitude, the armor layer will generate a large load on the cable, resulting in higher requirements for the load-bearing capacity of the cable when hoisted at high altitude. Therefore, it is necessary to develop a cable with a lightweight armor structure to solve the above problems. Utility Model Content

[0008] Preferably, the insulating layer is made of polyvinyl chloride, and the filling layer is made of aramid yarn.

[0009] Preferably, the heat insulation layer is glass fiber, and the protective cover is polyurethane.

[0010] The beneficial effects of the present invention are as follows: the present invention utilizes support bars and steel wire ropes in alternating intervals to form an armor layer of the cable, thereby protecting the cable from destruction and damage by external mechanical forces; the support bars are light in weight; and compared with an armor layer having a single metal structure, the armor layer composed of the combination of support bars and steel wire ropes reduces the weight of the armor layer while ensuring strength, thereby achieving lightweight armor layer, reducing the load generated by the armor layer on the cable, and lowering the requirements for load bearing capacity of the cable when hoisted at high altitudes.

[0015] See Figures 1 to 2 The cable shown has a lightweight armored structure, including a core 11, an insulation layer 14 and a protective sleeve 16. There are three cores 11, and the three cores 11 are all arranged on the inner side of the insulation layer 14. The insulation layer 14 is arranged on the inner side of the protective sleeve 16. The outer sides of the three cores 11 are provided with an insulation layer 12, and the insulation layer 12 is in contact with the inner wall of the insulation layer 14. A filling layer 13 is provided between the three insulation layers 12 and the insulation layer 14. An installation sleeve 15 is provided on the outer side of the insulation layer 14, and a plurality of support bars 17 are provided on the outer side of the installation sleeve 15 at equal intervals. A steel wire rope 18 is provided between two adjacent support bars 17, and the support bars 17 and the steel wire rope 18 are in contact with the inner wall of the protective sleeve 16.

[0016] Furthermore, the mounting sleeve 15 and the plurality of support bars 17 are an integral structure, and the cross-section of the support bars 17 is a triangular structure; the plurality of support bars 17 are fixed at equal intervals on the surface of the mounting sleeve 15 and can be installed together with the mounting sleeve 15. The support bars 17 with a triangular structure have good stability and high structural strength. The support bars 17 and the steel wire ropes 18 are alternately spaced to form an armor layer of the cable, which protects the cable from destruction and damage by external mechanical forces. The weight of the support bars 17 is small. Compared with the armor layer of a single metal structure, the armor layer composed of the combination of the support bars 17 and the steel wire ropes 18 reduces the weight of the armor layer while ensuring strength, thereby achieving lightweight armor layer, reducing the load generated by the armor layer on the cable, and reducing the load-bearing capacity requirements of the cable when it is hoisted at high altitudes.

[0017] Furthermore, the mounting sleeve 15 and the support bar 17 are both made of modified polyamide; the mounting sleeve 15 and the support bar 17 made of modified polyamide have the advantages of high strength and light weight.

[0018] Furthermore, the insulating layer 12 is made of polyvinyl chloride, and the filling layer 13 is made of aramid yarn. The insulating layer 12 made of polyvinyl chloride has good insulation performance, and the filling layer 13 made of aramid yarn is light in weight and has good thermal insulation performance.

[0019] Furthermore, the thermal insulation layer 14 is made of glass fiber, and the protective cover 16 is made of polyurethane; the thermal insulation layer 14 of glass fiber has good thermal insulation performance and can reduce the impact of the external ambient temperature on the wire core 11, and the protective cover 16 of polyurethane has strong wear resistance, acid and alkali resistance, and can effectively protect the cable.

[0020] The working principle of the present invention is that the armor layer of the cable is composed of support bars 17 and steel wire ropes 18 that are alternately spaced. The support bars 17 made of modified polyamide have high strength, and the triangular cross-sectional structure of the support bars 17 further enhances its own strength. Compared with the steel wire ropes 18 made of metal, the overall strength of the support bars 17 is not bad, thereby ensuring the strength of the armor layer composed of the support bars 17 and the steel wire ropes 18. The support bars 17 made of modified polyamide are light in weight. Compared with the armor layer with a single metal structure, the armor layer composed of the combination of the support bars 17 and the steel wire ropes 18 reduces the weight of the armor layer while ensuring strength, thereby achieving lightweight armor layer.

[0021] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
