Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a high-strength tensile-resistant high-voltage cable. Background Art

[0002] Tensile high-voltage cable is a special cable that combines the characteristics of tensile cable and high-voltage cable, with high tensile strength and high-voltage transmission capacity. This cable is designed to withstand high mechanical stress, especially in situations where the cable needs to move back and forth and withstand certain mechanical stress, such as cable tracks, transportation lines, handling machines, cranes, elevators, etc. Tensile high-voltage cable is not only suitable for dry or humid indoor and outdoor environments, but also particularly suitable for applications with high mechanical stress resistance, especially applications where tensile and torsional stresses exist at the same time.

[0003] The tensile cable in the prior art is usually designed with improvements in tensile strength and tensile strength. The wire cores that make up the cable, especially the copper core, are usually recycled after the cable is scrapped. In the prior art, a cable stripping machine is often used to strip the cable to be recycled. The staff needs to carry a cable stripping machine when recycling the cable core material, which is inconvenient to operate. Therefore, it is necessary to improve the design of the relevant technology. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a high-strength tensile-resistant high-voltage cable.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: a high-strength tensile-resistant high-voltage cable, comprising a cable sheath and a cable core arranged in the cable sheath, an auxiliary stripping assembly is arranged in the cable sheath, the auxiliary stripping assembly comprises a pulling block embedded in the cable sheath close to the outer wall of the cable sheath, and a cutting steel wire fixed to the side wall of the pulling block and embedded in the cable sheath, the length direction of the cutting steel wire is parallel to the length direction of the cable core.

[0006] By adopting the above technical solution, the setting of the skin-cutting steel wire and the pulling block, when the core material of the cable needs to be recovered, the staff first needs to fix the two ends of the cable, and then only needs to clamp the pulling block with tools such as pliers and pull it outward to separate the cable sheath through the skin-cutting steel wire, eliminating the tedious operation of the staff carrying a special cable stripping machine, and improving the efficiency of cable core recovery. In addition, the skin-cutting steel wire is set in the cable sheath, and the skin-cutting steel wire has high hardness and strength, which improves the tensile strength of the cable and is conducive to extending the service life of the cable.

[0007] Furthermore, the diameter of the skin-cutting steel wire is 0.5-1 mm, and the skin-cutting steel wires on the pulling block are provided in plurality and are evenly arranged.

[0008] By adopting the above technical solution, the restriction on the diameter of the cutting wire is conducive to reducing the resistance of the cutting wire when passing through the pulling block, making it easier to strip the cable. Multiple cutting wires work together to cut the cable sheath at multiple points when the pulling block is pulled, thereby speeding up the stripping speed.

[0009] Furthermore, two pulling blocks are provided and symmetrically fixed at the two ends of the cut-skin steel wire, and the two pulling blocks are respectively located near the ends of the cable sheath.

[0010] By adopting the above technical solution, the pulling block is clamped and pulled by two pliers respectively, so that stripping action can be performed from both ends of the cable at the same time, thereby improving the stripping efficiency.

[0011] Furthermore, a plurality of spikes are evenly arranged on one side of the skin-cutting steel wire away from the axis of the cable sheath.

[0012] By adopting the above technical solution, the setting of the spikes enables the staff to separate the cable sheath with the spikes when pulling the skin-cutting wire through the pulling block, thereby improving the efficiency of breaking the cable sheath and facilitating the recovery efficiency of the cable core.

[0013] Furthermore, the auxiliary stripping components are provided with two groups, and the angle between the pulling blocks in the two groups of the auxiliary stripping components and the cable sheath axis is α, and the angle α is 150°-170°.

[0014] By adopting the above technical solution, the two sets of auxiliary stripping components are staggered, avoiding the relative arrangement of the two sets of auxiliary stripping components, and preventing the cable from splitting itself when squeezed due to the relative arrangement of the two sets of auxiliary stripping components.

[0015] Furthermore, an inclined surface is provided at the intersection between the side of the pulling block away from the cable sheath axis and the side wall of the pulling block, and a plurality of anti-slip convex strips are provided on the side walls on both sides of the pulling block.

[0016] By adopting the above technical solution and setting the inclined surface, it is convenient for the staff to insert the tool into the cable sheath, clamp the pulling block by the tool and pull it outwards, and the anti-slip convex strip reduces the probability of slipping.

[0017] Furthermore, a steel mesh is arranged in the cable sheath at a position close to the pulling block, and an indication area flush with the outer wall of the cable sheath is arranged at a position corresponding to the steel mesh and the pulling block.

[0018] By adopting the above technical solution, the setting of the indication area makes it easier for the staff to quickly find the pulling block and pull it when the wire core is recovered later. The setting of the steel mesh ensures the structural strength of the indication area.

[0019] Furthermore, the indication area is made of waterproof material, and a waterproof coating is provided in the cable sheath at a position close to the edge of the indication area.

[0020] By adopting the above technical solution, a good waterproof effect is achieved.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. In this application, the setting of the skin-cutting steel wire and the pulling block, when the core material of the cable needs to be recovered, the staff first needs to fix the two ends of the cable, and then only needs to clamp the pulling block with tools such as pliers and pull it outwards, so that the cable sheath can be separated by the skin-cutting steel wire, eliminating the tedious operation of the staff carrying a special cable stripping machine, and improving the efficiency of cable core recovery;

[0023] 2. In this application, the restriction on the diameter of the cutting wire is conducive to reducing the resistance of the cutting wire when passing through the pulling block, which is convenient for stripping the cable. Multiple cutting wires work together to cut the cable sheath at multiple points when the pulling block is pulled, which speeds up the stripping speed;

[0024] 3. In the present application, the setting of the inclined surface makes it easier for the staff to insert the tool into the cable sheath, and the tool is used to clamp the pulling block and pull it outward, and the anti-slip convex strip reduces the probability of slipping.
