Description

Technical Field

[0001] The utility model relates to the technical field of mining anchor cables, in particular to a mining anchor cable structure with high bearing capacity. Background Art

[0002] Mining anchor cables are a type of anchoring equipment specifically used in mining projects. They are used to fix and support structures, equipment or retaining walls in mines. Mining anchor cables are usually composed of high-strength steel strands or cables to provide sufficient tensile strength and stability. Due to the particularity of the mining environment, mining anchor cables need to be able to withstand high tension, heavy loads and harsh working conditions. They play an important role in mining projects to ensure the safety of mining equipment and workers. The steel strand in the anchor cable is a metal product made of multiple steel wires mechanically twisted together.

[0003] The above-mentioned existing technical solutions have the following defects: the steel strands in the existing anchor cables are simply twisted together by several steel wires, so that the structural strength of the steel strands is limited and the bearing capacity still needs to be further improved. Utility Model Content

[0004] The utility model aims to provide a mining anchor cable structure with high bearing capacity.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A high-bearing-capacity mining anchor cable structure comprises a first steel wire, a reinforcing steel wire is twisted around the outer side of the first steel wire, and a first fixing steel wire is spirally wound around the outer side of the reinforcing steel wire;

[0007] The interior of the reinforcing steel wire includes a second steel wire, a third steel wire, a second anti-corrosion layer and a second fixed steel wire. The third steel wire is twisted and wrapped around the outside of the second steel wire. The second anti-corrosion layer is sprayed on the outside of the second and third steel wires. The second fixed steel wire is spirally wrapped around the outside of the third steel wire.

[0008] By adopting the above technical scheme, the original steel strands are multiple steel wires twisted and wound. Now each twisted and wound steel wire is treated as a separate individual for structural reinforcement. A steel wire is placed in the center and twisted and wound around the steel wire. Then a fixed steel wire is spirally wound on the outside for reinforcement to prevent the twisted structure from spreading. At the same time, the structural strength of each reinforced steel wire is also guaranteed. Then, multiple reinforced reinforcement steel wires are twisted and wound around the first steel wire, and then a second fixed steel wire is spirally wound on the outside of the twisted steel wire to form a complete anchor cable steel strand. Both the internal and external structures are reinforced to ensure the high bearing capacity of the steel strand structure.

[0009] Furthermore, a first anti-corrosion layer is sprayed on the outer side of the first steel wire, and the diameter of the first steel wire is greater than the diameter of the reinforcement steel wire.

[0010] By adopting the above technical solution and adding an anti-corrosion layer, the anti-corrosion effect of the internal steel wire structure can be guaranteed to avoid rust and decay.

[0011] Furthermore, the reinforcement steel wires are provided in a plurality of groups, and each group of the third steel wires is provided in plurality.

[0012] By adopting the above technical solution, by setting up multiple groups of reinforcing steel wires, and the reinforcing steel wires themselves are formed by twisting and winding multiple steel wires, and then twisting and winding multiple groups of reinforcing steel wires with the first steel wire, the structural strength of the anchor cable steel strand can be greatly improved.

[0013] Furthermore, the diameter of the second steel wire is the same as the diameter of the third steel wire, and the diameter of the second steel wire is smaller than the diameter of the first steel wire.

[0014] By adopting the above technical solution and adding multiple groups of steel wires with different diameters and thicknesses, the steel wire with a larger diameter can be used as the center, and the steel wire with a smaller diameter can be twisted and twisted to ensure the structural strength of the center part.

[0015] Furthermore, outer sides of the first fixing steel wire and the second fixing steel wire are both galvanized.

[0016] By adopting the above technical solution, the surface of the outer fixed steel wire is galvanized, which can improve the surface anti-corrosion effect of the outermost steel wire.

[0017] In summary, the beneficial technical effects of the utility model are:

[0018] A first steel wire, a reinforcing steel wire and a fixed steel wire are used. A plurality of small steel wires are twisted together to form a reinforcing steel wire. Then, a plurality of groups of reinforcing steel wires are twisted together with the first steel wire to form a complete anchor cable steel strand. The strength of the internal structure of the steel strand is improved by twisting multiple groups and winding layers. At the same time, fixed steel wires are wound around the outside of the reinforcing steel wire and the third steel wire, which can improve the structural strength of the outside of the steel strand and prevent the twisting position from spreading, thereby ensuring that the steel strand can be used stably and normally, resulting in an effect of improving the bearing capacity.
