Description

Technical Field

[0001] The invention relates to the field of cables, in particular to a high-strength cable and an installation method thereof. Background Art

[0002] At present, in order to facilitate the winding management and laying of cables, soft insulation is used to wrap the wire core. Although soft insulation can meet the needs of insulation wrapping, due to its soft characteristics and the limited thickness of existing soft insulation, the compression and impact resistance of existing cables are very limited. In this way, when there is a large pressure (such as underground installation or other environments where heavy objects are pressed) or a large impact (such as exposed installation and environments where collisions are easily caused by human activities) in the environment where such cables are installed and used, it is easy for the insulation to break and the wire core to deform and be damaged, which will not only reduce the performance of the cable, but also reduce the service life of the cable and reduce the safety of the cable, which will pose a great safety hazard. Therefore, it is very necessary to redesign the structure of the cable. Summary of the invention

[0003] The object of the present invention is to solve the above-mentioned problems and shortcomings, and to provide a high-strength cable and an installation method thereof. The high-strength cable can form a structure that comprehensively strengthens and protects the wire core, which can greatly improve the performance of withstanding high pressure and high impact. It can play an extremely good protective role on the wire core, and can effectively avoid the probability of the wire core being deformed and damaged under high pressure or high impact. It can not only enable the cable to maintain good performance for a long time, but also extend the service life of the cable, and can greatly improve the safety of cable use, thereby effectively reducing the potential safety hazards of cable use; the installation method is very simple to operate, which is not only conducive to achieving efficient installation, but also conducive to obtaining cables with high strength, high performance, long life, high safety and few potential safety hazards.

[0004] The technical solution of the present invention is achieved in this way: A high-strength cable, characterized in that it includes a wire core, an inner insulating layer, an inner spiral reinforcement layer, a steel mesh layer, an outer spiral reinforcement layer, and an outer insulating layer, which are arranged in sequence from the inside to the outside, wherein the inner spiral reinforcement layer and the outer spiral reinforcement layer are both composed of spiral steel bars with spiral gaps, the spiral gaps on the inner spiral reinforcement layer form inner spiral holes between the steel mesh layer and the inner insulating layer, and the spiral gaps on the outer spiral reinforcement layer form outer spiral holes between the steel mesh layer and the outer insulating layer, and the inner spiral holes and the outer spiral holes are both filled with curable epoxy resin.

[0005] Preferably, the first steel mesh and the second steel mesh are respectively arranged on the two outer side walls of the inner spiral reinforcement layer corresponding to the length direction of the wire core, and the first steel mesh and the second steel mesh are extended along the spiral direction of the inner spiral reinforcement layer, and the first steel mesh and the second steel mesh are overlapped together in the inner spiral hole.

[0006] Preferably, a third steel mesh and a fourth steel mesh are respectively arranged on the two outer side walls of the outer spiral reinforcement layer corresponding to the length direction of the wire core, and the third steel mesh and the fourth steel mesh are extended along the spiral direction of the outer spiral reinforcement layer, and the third steel mesh and the fourth steel mesh are overlapped together in the outer spiral hole.

[0007] Preferably, an inner steel mesh is sandwiched between the inner spiral reinforcement layer and the inner insulation layer.

[0008] Preferably, the inner steel mesh is arranged in a mesh cylinder shape surrounding the inner insulating layer.

[0009] Preferably, an outer steel mesh is sandwiched between the outer spiral reinforcement layer and the outer insulation layer.

[0010] Preferably, the outer steel mesh is arranged in a mesh cylinder shape surrounding the outer spiral reinforcement layer.

[0011] Preferably, the inner spiral reinforcement layer and the outer spiral reinforcement layer are both composed of hollow spiral steel pipes.

[0012] Preferably, a plurality of inner through holes penetrating to the inner hole of the inner spiral reinforcement layer are formed on the outer wall thereof; and a plurality of outer through holes penetrating to the inner hole of the outer spiral reinforcement layer are formed on the outer wall thereof.

[0013] A method for installing the above-mentioned high-strength cable is characterized in that it includes the following steps: Prepare high-strength cables, liquid epoxy resin, curing agent, vacuum pump, filling pump, and sealing tape; Laying of high-strength cables; Use sealing tape to seal both ends of the high-strength cable to close the two openings of the inner spiral hole and the outer spiral hole; The air suction end of the air pump is connected to an orifice of the inner spiral hole, and the liquid discharge end of the liquid filling pump is connected to an orifice of the outer spiral hole, and the air suction end of the air pump and the liquid discharge end of the liquid filling pump are respectively located at two ends of the high-strength cable; Mixing a liquid epoxy resin and a curing agent to obtain a curable epoxy resin; The curable epoxy resin is pumped into the inner spiral hole and the outer spiral hole by using a liquid filling pump, and the air is simultaneously pumped out by using an air pump; After the inner spiral hole and the outer spiral hole are filled with curable epoxy resin, the vacuum pump and the filling pump are stopped; Finally, wait for the epoxy resin mixture to cure.

[0014] The beneficial effects of the present invention are as follows: the high-strength cable includes a wire core, an inner insulating layer, an inner spiral reinforcement layer, a steel mesh layer, an outer spiral reinforcement layer, and an outer insulating layer, which are arranged in sequence from the inside to the outside, and the inner spiral reinforcement layer and the outer spiral reinforcement layer are both composed of spiral steel bars with spiral gaps, and the spiral gaps on the inner spiral reinforcement layer form inner spiral holes between the steel mesh layer and the inner insulating layer, and the spiral gaps on the outer spiral reinforcement layer form outer spiral holes between the steel mesh layer and the outer insulating layer, and curable epoxy resin is filled in the inner spiral holes and the outer spiral holes. The use of spiral steel bars to form the inner spiral reinforcement layer and the outer spiral reinforcement layer can not only play a multi-directional reinforcement role, but also ensure that the reinforcement effect is very strong. The steel mesh layer can not only play a stable and reliable separation and restriction role for the inner spiral reinforcement layer and the outer spiral reinforcement layer, but also play a role in strengthening the structure, and can facilitate the fusion of the epoxy resins in the inner spiral hole and the outer spiral hole. This allows the inner spiral reinforcement layer, steel mesh layer, and outer spiral reinforcement layer to be integrated into an ultra-high strength reinforcement layer through the cured epoxy resin, and this reinforcement layer surrounds the wire core. Therefore, the high-strength cable can form a structure that fully reinforces and protects the wire core, which can greatly improve the performance of withstanding high pressure and high impact, and can provide excellent protection for the wire core, effectively avoiding the probability of deformation and damage of the wire core under high pressure or high impact. It can not only maintain good performance of the cable for a long time, but also extend the service life of the cable, and greatly improve the safety of the cable, thereby effectively reducing the potential safety hazards of cable use.

[0015] In the installation method of the high-strength cable, after the high-strength cable is laid, the inner spiral hole and the outer spiral hole are filled with curable epoxy resin, so that the high-strength cable can be installed in place conveniently, and the high-strength cable can be stably positioned at the installation position through the cured epoxy resin, and the epoxy resin, the inner spiral reinforcement layer, the steel mesh layer and the outer spiral reinforcement layer can be used to comprehensively and effectively protect the wire core, which can make the high-strength cable have very high pressure resistance and collision resistance, so as to make the high-strength cable maintain high performance and safety for a long time. Such an installation method is very simple to operate, which can not only help to achieve efficient installation, but also help to obtain a high-strength, high-performance, long-life, high-safety and less potential safety cable. The suction end of the vacuum pump is connected to an orifice of the inner spiral hole, and the liquid outlet end of the filling pump is connected to an orifice of the outer spiral hole, and the suction end of the vacuum pump and the liquid outlet end of the filling pump are respectively located at the two ends of the high-strength cable. In this way, the curable epoxy resin can quickly and fully fill the inner spiral hole and the outer spiral hole. This installation method can accurately and stably obtain high-strength cables, which can ensure that the high-strength cables have very high pressure resistance and collision resistance.

[0022] like Figure 1 and Figure 2 As shown, a high-strength cable described in the present invention includes a wire core 1, an inner insulating layer 2, an inner spiral reinforcement layer 3, a steel mesh layer 4, an outer spiral reinforcement layer 5, and an outer insulating layer 6, which are arranged in sequence from the inside to the outside, wherein the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5 are both composed of spiral steel bars with spiral gaps, the spiral gaps on the inner spiral reinforcement layer 3 form inner spiral holes 10 between the steel mesh layer 4 and the inner insulating layer 2, and the spiral gaps on the outer spiral reinforcement layer 5 form outer spiral holes 20 between the steel mesh layer 4 and the outer insulating layer 6, and the inner spiral holes 10 and the outer spiral holes 20 are both filled with curable epoxy resin 30.

[0023] The high-strength cable comprises a wire core 1, an inner insulating layer 2, an inner spiral reinforcement layer 3, a steel mesh layer 4, an outer spiral reinforcement layer 5, and an outer insulating layer 6, which are arranged in sequence from the inside to the outside, and the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5 are both composed of spiral steel bars with spiral gaps, and the spiral gaps on the inner spiral reinforcement layer 3 form inner spiral holes 10 between the steel mesh layer 4 and the inner insulating layer 2, and the spiral gaps on the outer spiral reinforcement layer 5 form outer spiral holes 20 between the steel mesh layer 4 and the outer insulating layer 6, and curable epoxy resin 30 is filled in the inner spiral holes 10 and the outer spiral holes 20. The use of spiral steel bars to form the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5 can not only play a multi-directional reinforcement role, but also ensure that the reinforcement effect is very strong. The steel mesh layer 4 can not only play a stable and reliable separation and restriction role for the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5, but also play a role in strengthening the structure, and can facilitate the fusion of the epoxy resin 30 in the inner spiral hole 10 and the outer spiral hole 20. This allows the inner spiral reinforcement layer 3, the steel mesh layer 4, and the outer spiral reinforcement layer 5 to be integrated into a super-high strength reinforcement layer through the cured epoxy resin 30, and this reinforcement layer surrounds the wire core 1. Therefore, the high-strength cable can form a structure that can fully strengthen and protect the wire core, which can greatly improve the performance of withstanding high pressure and high impact, and can play an excellent protective role on the wire core, and can effectively avoid the probability of deformation and damage of the wire core under high pressure or high impact. It can not only keep the cable in good performance for a long time, but also extend the service life of the cable, and can greatly improve the safety of the cable, thereby effectively reducing the potential safety hazards of the cable.

[0024] Filling the curable epoxy resin 30 can not only play a very high reinforcing role, but also play a very good insulating role, which can ensure that the high-strength cable has a very high insulation performance.

[0025] like Figures 1 to 3As shown, the first steel mesh 31 and the second steel mesh 32 are respectively arranged on the two outer side walls of the inner spiral reinforcement layer 3 corresponding to the length direction of the wire core 1, and the first steel mesh 31 and the second steel mesh 32 are extended along the spiral direction of the inner spiral reinforcement layer 3, and the first steel mesh 31 and the second steel mesh 32 are overlapped together in the inner spiral hole 10. The use of the first steel mesh 31 and the second steel mesh 32 can not only ensure that they have high structural strength, but also can better strengthen the inner spiral reinforcement layer 3, and can allow liquid epoxy resin 30 to pass through, so that the epoxy resin 30 can fill the inner spiral hole 10; and after the epoxy resin 30 is cured, the first steel mesh 31 and the second steel mesh 32 can be wrapped, which can make the overlapped first steel mesh 31 and the second steel mesh 32 play a mutually restricted reinforcement role through the cured epoxy resin 30, so as to play a more stable and reliable reinforcement role in the inner spiral hole 10, which can further enhance the reinforcement effect of the inner spiral reinforcement layer 3, thereby helping to further improve the compression and collision resistance of the high-strength cable.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a third steel mesh 51 and a fourth steel mesh 52 are respectively arranged on the two outer side walls of the outer spiral reinforcement layer 5 corresponding to the length direction of the wire core 1, and the third steel mesh 51 and the fourth steel mesh 52 are extended along the spiral direction of the outer spiral reinforcement layer 5, and the third steel mesh 51 and the fourth steel mesh 52 are overlapped together in the outer spiral hole 20. The use of the third steel mesh 51 and the fourth steel mesh 52 can not only ensure that they have high structural strength, but also can better strengthen the outer spiral reinforcement layer 5, and can allow liquid epoxy resin 30 to pass through, so that the epoxy resin 30 can fill the outer spiral hole 20; and after the epoxy resin 30 is cured, the third steel mesh 51 and the fourth steel mesh 52 can be wrapped, which can make the overlapped third steel mesh 51 and the fourth steel mesh 52 play a mutually restricted reinforcement role through the cured epoxy resin 30, so as to play a more stable and reliable reinforcement role in the outer spiral hole 20, which can further enhance the reinforcement effect of the outer spiral reinforcement layer 5, thereby helping to further improve the compression and collision resistance of the high-strength cable.

[0027] The first steel mesh 31 and the second steel mesh 32 are welded and fixed on the inner spiral reinforcement layer 3; the third steel mesh 51 and the fourth steel mesh 52 are welded and fixed on the outer spiral reinforcement layer 5, which not only facilitates manufacturing but also makes the overall structure very stable and reliable.

[0028] like Figure 2As shown, an inner steel mesh 7 is sandwiched between the inner spiral reinforcement layer 3 and the inner insulating layer 2. The inner steel mesh 7 can not only ensure that it has high structural strength, but also make the inner steel mesh 7 have very stable and reliable limiting, isolating and reinforcing functions, so that the inner insulating layer 2 can ensure high stability and prevent the inner insulating layer 2 from being adversely affected by the inner spiral reinforcement layer 3; and the inner steel mesh 7 can also be acted on by the epoxy resin 30, so that the epoxy resin 30 can be cured on the inner steel mesh 7 and form a reliable reinforcement layer, thereby helping to further improve the compression and collision resistance of the high-strength cable.

[0029] like Figure 1 and Figure 2 As shown, the inner steel mesh 7 is arranged in a mesh tube shape around the inner insulating layer 2. This enables the inner steel mesh 7 to play a more comprehensive and effective reinforcement role, thereby further improving the compression and collision resistance of the high-strength cable.

[0030] like Figure 2 As shown, an outer steel mesh 8 is sandwiched between the outer spiral reinforcement layer 5 and the outer insulation layer 6. The outer steel mesh 8 can not only ensure that it has high structural strength, but also make the outer steel mesh 8 have very stable and reliable restriction, isolation and reinforcement functions, so that the outer insulation layer 6 can ensure high stability and prevent the outer insulation layer 6 from being adversely affected by the outer spiral reinforcement layer 5; and the outer steel mesh 8 can also be acted on by the epoxy resin 30, so that the epoxy resin 30 can be cured on the outer steel mesh 8 and form a reliable reinforcement layer, thereby helping to further improve the compression and collision resistance of the high-strength cable.

[0031] like Figure 1 and Figure 2 As shown, the outer steel mesh 8 is arranged in a mesh tube shape around the outer spiral reinforcement layer 5. This enables the outer steel mesh 8 to play a more comprehensive and effective reinforcement role, thereby further improving the compression and collision resistance of the high-strength cable.

[0032] like Figures 1 to 6 As shown, the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5 are both made of hollow spiral steel pipes. This not only facilitates the bending of the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5, but also reduces the amount of material used on the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5 when making thick inner spiral holes 10 and outer spiral holes 20, which is conducive to improving the applicability of high-strength cables in the above environment.

[0033] like Figure 5 and Figure 6As shown, the outer wall of the inner spiral reinforcement layer 3 is provided with a plurality of inner through holes 33 penetrating to the inner hole thereof; the outer wall of the outer spiral reinforcement layer 5 is provided with a plurality of outer through holes 53 penetrating to the inner hole thereof. This can guide the epoxy resin 30 into the inner hole of the inner spiral reinforcement layer 3 by means of the inner through holes 33, and guide the epoxy resin 30 into the inner hole of the outer spiral reinforcement layer 5 by means of the outer through holes 53; or when the inner holes of the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5 are filled with the epoxy resin 30, the inner through holes 33 are used to fill the epoxy resin into the inner spiral hole 10, and the outer through holes 53 are used to fill the epoxy resin into the outer spiral hole 20. This can facilitate the filling of the inner spiral reinforcement layer 3 and the outer spiral reinforcement layer 5 with epoxy resin, thereby further enhancing the strength of the high-strength cable structure, and further helping to further improve the compression resistance and anti-collision performance of the high-strength cable.

[0034] In the actual manufacturing process, the steel mesh layer 4, the first steel mesh 31, the second steel mesh 32, the third steel mesh 51, the third steel mesh 51, the inner steel mesh 7 and the outer steel mesh 8 are all woven with stainless steel wire strips with a larger diameter (diameter greater than 1.5 mm), so that they have high structural strength and durability, thereby helping to further improve the structural strength of the high-strength cable. Example

[0035] like Figure 1 and Figure 2 As shown, a method for installing the high-strength cable described in Embodiment 1 includes the following steps: Prepare high-strength cables, liquid epoxy resin, curing agent (the liquid epoxy resin and curing agent can be liquid epoxy resin and curing agent that can be cured to form hard epoxy resin after mixing, and their proportions can also be proportions that can form hard epoxy resin after curing, so that the needs of actual manufacturing and use can be met), vacuum pump, filling pump, and sealing tape; Laying of high-strength cables; Seal both ends of the high-strength cable with sealing tape to close the two openings of the inner spiral hole 10 and the outer spiral hole 20; The air suction end of the air pump is butted against an orifice of the inner spiral hole 10, and the liquid discharge end of the liquid filling pump is butted against an orifice of the outer spiral hole 20, and the air suction end of the air pump and the liquid discharge end of the liquid filling pump are respectively located at two ends of the high-strength cable (the butt connection can be achieved by inserting a pipe connecting the inner spiral hole 10 and the air suction end of the air pump on the sealing tape on the orifice of the inner spiral hole 10, and the butt connection can be achieved by inserting a pipe connecting the outer spiral hole 20 and the liquid discharge end of the liquid filling pump on the sealing tape on the orifice of the outer spiral hole 20); Mixing a liquid epoxy resin and a curing agent to obtain a curable epoxy resin 30; The curable epoxy resin 30 is pumped into the inner spiral hole 10 and the outer spiral hole 20 by using a filling pump, and the air is simultaneously pumped out by using an air pump; After the inner spiral hole 10 and the outer spiral hole 20 are filled with the curable epoxy resin 30, the vacuum pump and the filling pump are stopped; Finally, wait for the epoxy resin mixture to cure.

[0036] In the installation method of the high-strength cable, after the high-strength cable is laid, the inner spiral hole 10 and the outer spiral hole 20 are filled with curable epoxy resin 30, so that not only the high-strength cable can be easily installed in place, but also the high-strength cable can be stably positioned at the installation position through the cured epoxy resin 30, and the epoxy resin 30, the inner spiral reinforcement layer 3, the steel mesh layer 4 and the outer spiral reinforcement layer 5 can be used together to play a comprehensive and effective protective role on the wire core 1, which can make the high-strength cable have very high pressure resistance and collision resistance, so as to help the high-strength cable maintain high performance and safety for a long time. Such an installation method is very simple to operate, which is not only conducive to efficient installation, but also conducive to obtaining a cable with high strength, high performance, long life, high safety and fewer safety hazards.

[0037] The suction end of the vacuum pump is connected to an opening of the inner spiral hole 10, and the liquid outlet end of the filling pump is connected to an opening of the outer spiral hole 20, and the suction end of the vacuum pump and the liquid outlet end of the filling pump are respectively located at the two ends of the high-strength cable. In this way, the curable epoxy resin 30 can quickly and fully fill the inner spiral hole 10 and the outer spiral hole 20. This installation method can accurately and stably obtain a high-strength cable, which can ensure that the high-strength cable has very high pressure resistance and collision resistance.
