Novel mine steel wire mesh armoured tube

Abstract

This utility model relates to a novel steel wire mesh armored bundled tube for mining. It includes a first armored bundled tube, a second armored bundled tube, and a steel wire mesh tube. The steel wire mesh tube is fitted inside the first armored bundled tube. Several groups of second armored bundled tubes arranged in a circumferential array are arranged inside the steel wire mesh tube. This invention solves the technical problems in existing technologies where bundled tubes often use a single-layer armor or loosely bound multi-tube structure, lacking effective support between the sub-tubes. Under pressure, these sub-tubes are prone to mutual friction and wear, reducing their service life. Especially when the bundled tube needs to be laid in a bent manner, the outer armor is prone to cracking, and uneven displacement of the inner sub-tubes leads to localized stress concentration.

Description

Technical Field

[0001] This utility model relates to the field of bundled tubes, and in particular to a novel steel wire mesh armored bundled tube for mining. Background Technology

[0002] Mining bundled tubes play a crucial role in underground gas monitoring and communication transmission, but traditional bundled tube structures suffer from insufficient compressive strength and susceptibility to deformation and damage. The complex mining environment exposes bundled tubes to external forces such as rock compression and equipment collisions. A single armor layer or ordinary plastic tube body cannot withstand high-intensity mechanical impacts over extended periods, leading to internal pipeline breakage or signal transmission interruption. Furthermore, existing bundled tubes often employ single-layer armor or loosely bundled multi-tube structures, lacking effective support between sub-tubes. Under pressure, these sub-tubes are prone to mutual friction and wear, reducing their service life. Especially when the bundled tubes need to be laid in a bent configuration, the outer armor layer is prone to cracking, and uneven displacement of the inner sub-tubes leads to localized stress concentration. Therefore, there is an urgent need for a mining bundled tube structure that combines high compressive strength, bending resistance, and internal pipeline stability. This structure should address the technical problems of insufficient mechanical strength and susceptibility to displacement and damage of sub-tubes in traditional bundled tubes through multi-layered collaborative protection and internal rigid support. Utility Model Content

[0003] This application provides a novel type of mining wire mesh armored bundled tube, which solves the technical problems in the prior art where bundled tubes mostly adopt a single-layer armor or loosely bound multi-tube structure, lacking effective support between the sub-tubes, and easily rubbing and wearing each other under pressure, reducing service life. In particular, when the bundled tube needs to be laid in a bent manner, the outer armor is prone to cracking, and the inner tube sub-tubes cause local stress concentration due to uneven displacement.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A novel type of mining steel wire mesh armored bundle tube includes a first armored bundle tube, a second armored bundle tube, and a steel wire mesh tube; the steel wire mesh tube is attached to the inner side of the first armored bundle tube; the inner cavity of the steel wire mesh tube is provided with a plurality of groups of the second armored bundle tubes arranged in a circumferential array.

[0006] As a further improvement to the above technical solution:

[0007] The second armored bundle consists of seven groups.

[0008] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0009] 1. By employing a multi-layered composite structure consisting of a first armored bundle of tubes, a second armored bundle of tubes, and a wire mesh, the overall mechanical properties and sub-tube stability are significantly improved. The first armored bundle of tubes serves as the main load-bearing layer, resisting external rock impacts and equipment compression. The wire mesh not only distributes external pressure to each second armored bundle of tubes but also buffers vibrations through its mesh-like elastic structure, preventing direct friction between the sub-tubes. The circumferential array of seven sets of second armored bundles is evenly stressed under the fixation of the wire mesh, preventing displacement or skew even during bending installation, ensuring the internal pipelines remain protected. Furthermore, the flexibility of the wire mesh allows the bundle of tubes to adapt to tunnel bends, while its close fit with the first armored bundle of tubes prevents the risk of armor layer cracking. This structure achieves a synergistic improvement in compressive and bending resistance without increasing the tube wall thickness, extending the service life of the bundle of tubes in complex mining environments and reducing maintenance costs. The overall solution solves the technical problems of traditional bundled tubes being prone to wear and having poor impact resistance, and is especially suitable for long-distance, high-stress mining environments.

[0013] This application provides a novel type of mining wire mesh armored bundled tube, which solves the technical problems in the prior art where bundled tubes mostly adopt a single-layer armor or loosely bound multi-tube structure, lacking effective support between the sub-tubes, and easily rubbing and wearing each other under pressure, reducing service life. In particular, when the bundled tube needs to be laid in a bent manner, the outer armor is prone to cracking, and the inner tube sub-tubes cause local stress concentration due to uneven displacement.

[0014] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] A new type of mining steel wire mesh armored bundle tube, such as Figure 1 and Figure 2As shown, it includes a first armored bundle tube 1, a second armored bundle tube 2, and a wire mesh tube 3; the wire mesh tube 3 is attached to the inner side of the first armored bundle tube 1; the inner cavity of the wire mesh tube 3 is provided with several groups of second armored bundle tubes 2 arranged in a circumferential array.

[0017] The second armored bundle tube 2 consists of seven groups.

[0018] The first armored bundle tube 1 is an outer metal armored tube, with its inner wall tightly fitted with a steel wire mesh tube 3. The steel wire mesh tube 3 is a mesh structure woven from high-strength steel wire, forming a flexible buffer layer. Seven sets of second armored bundle tubes 2 are evenly distributed within the inner cavity of the steel wire mesh tube 3. These second armored bundle tubes 2 are metal armored communication or gas transmission sub-tubes, arranged in a circumferential array and fixed in position by the mesh gaps of the steel wire mesh tube 3. During installation, the seven sets of second armored bundle tubes 2 are first inserted into the steel wire mesh tube 3, using the elastic clamping force of the steel wire mesh tube 3 to maintain their spacing; then, the assembly is embedded into the first armored bundle tube 1, and the three layers are tightly fitted together through a crimping process.

[0019] Operating procedures

[0020] During construction, the second armored bundle tube 2 is first connected to the functional lines (such as gas sampling tubes or optical fibers) as needed. Then, the seven sets of sub-tubes are inserted into the inner cavity of the wire mesh tube 3 to ensure that they are evenly distributed around the circumference. Next, the wire mesh tube 3 is fitted into the first armored bundle tube 1 and the three-layer structure is fixed by pressing with hydraulic equipment. Finally, the entire bundle tube is laid along the mine roadway. The curved sections adapt to deformation through the flexibility of the wire mesh tube 3, while the straight sections rely on the double protection of the first armored bundle tube 1 and the wire mesh tube 3 to resist external pressure.

[0021] Beneficial effects

[0022] The use of a first armored bundle tube 1, a second armored bundle tube 2, and a wire mesh tube 3, along with the multi-layered composite structure of the first armored bundle tube 1, the wire mesh tube 3, and the second armored bundle tube 2, significantly improves the overall mechanical properties and stability of the sub-tubes. The first armored bundle tube 1 serves as the main load-bearing layer, resisting external rock impacts and equipment compression. The wire mesh tube 3 not only distributes external pressure to each of the second armored bundle tubes 2 but also buffers vibration through its mesh-like elastic structure, preventing direct friction between the sub-tubes. The circumferential array of seven sets of second armored bundle tubes 2, fixed by the wire mesh tube 3, distributes stress evenly, preventing displacement or skew even during bending, ensuring the internal pipelines remain protected. Furthermore, the flexibility of the wire mesh tube 3 allows the bundle tubes to adapt to tunnel bends, while its close fit with the first armored bundle tube 1 prevents the risk of armor layer cracking. This structure achieves a synergistic improvement in compressive and bending resistance without increasing the tube wall thickness, extending the service life of the bundle tubes in complex mining environments and reducing maintenance costs. The overall solution solves the technical problems of traditional bundled tubes being prone to wear and having poor impact resistance, and is especially suitable for long-distance, high-stress mining environments.
