Description

Technical Field

[0001] The utility model belongs to the technical field of mining hoses, in particular to a mining double-resistance hose. Background Art

[0002] Mining hoses are usually important equipment parts used to transport gas (gas contains water, coal slag, etc.) in industries such as mines and coal mines. In the existing related technologies, mining hoses are used under harsh conditions, which makes them easy to be damaged or worn and collapsed. In order to ensure that the mining hoses are not easy to collapse during use, mining hoses are usually made of soft materials plus hard structures (such as steel wires) to ensure that the hoses are always at the maximum conveying capacity. However, the mining hoses made of steel wire structures are generally soft, which can easily lead to inconvenience in angle adjustment, so that the installation of mining hoses requires a high level of technology and experience; mining hoses are usually connected by fixed integrated flange connection, slip-on flange connection, and quick connector connection methods. Fixed integrated flange connection and slip-on flange connection require bolts and nuts for connection, which is inconvenient to install, while quick connector connection does not require bolts and nuts for fixing, but the fixity of the pipeline is not as good as that of flange connection. If the connection is improperly installed, it may cause leakage, breakage and other problems. For this reason, the utility model proposes a new solution to the above technical problems.

[0003] The utility model aims to provide a double-resistance hose for mining, which adopts a structural design in which a hose support structure is installed on the outside of the hose body and the outer layer of the hose is connected to a limit position, so as to achieve the effect of making the mining hose not easy to collapse and always maintaining the maximum conveying capacity.

[0004] Based on this, the utility model provides a double-resistance hose for mining, comprising:

[0005] A flexible hose body, wherein a cavity is provided in the flexible hose body for conveying materials;

[0006] A hose support structure, the hose support structure being equidistantly connected to the hose body to support the hose body;

[0007] The hose outer layer is connected to the hose support structure and the hose support structure is limited by the hose outer layer. The hardness of the hose support structure material is greater than that of the hose outer layer to ensure that the mining hose is not easy to collapse when used as a whole.

[0008] In the double-resistance hose for mining as described above, the hose support structure is equidistantly spirally wound around the hose body to form a thread for connection.

[0009] In the double-resistance hose for mining as described above, the spiral inclination angle of the hose support structure ranges from 84° to 88°.

[0010] In the double-resistance hose for mining as described above, the hose support structure is made of rigid polyvinyl chloride to support the hose body.

[0011] In the double-resistance hose for mining as described above, the hose support structure is designed with a circular cross-section to better support the hose body.

[0012] As described above, a double-resistance hose for mining has an outer layer provided with a connecting flat groove to enable the hose to be better connected to a screw-in sealing joint.

[0013] In the double-resistance hose for mining as described above, the screw-in sealing joint is provided with a threaded structure cooperating with the hose supporting structure to realize a detachable connection between the screw-in sealing joint and the mining hose.

[0014] As described above, the mining double-resistance hose, wherein the outer layer of the hose is made of soft polyvinyl chloride so that after being wrapped and connected to the hose support structure, the mining hose can be bent, adjusted and installed as a whole.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 3 As shown, the utility model embodiment provides a mining double-resistance hose, comprising:

[0026] A hose body 1, wherein a cavity 11 is arranged inside the hose body 1 for conveying materials; a hose support structure 2, wherein the hose support structure 2 is equidistantly connected to the hose body 1 to support the hose body 1; a hose outer layer 3, wherein the hose outer layer 3 is connected to the hose support structure 2 and the hose support structure 2 is limited by the hose outer layer 3, and the hardness of the hose support structure 2 is greater than that of the hose outer layer 3 to ensure that the mining hose is not easy to collapse when used as a whole.

[0027] Specifically, the hose support structure 2 is equidistantly spirally wound around the hose body 1 to form a thread for connection. The equidistant spiral design is sturdy and durable. On the one hand, the connection of the mining hose can provide good sealing performance and can withstand a certain pressure to ensure that the connection will not break or leak, avoid liquid or gas leakage, and ensure the normal operation of the equipment; on the other hand, the mining hose can be installed and disassembled through a simple rotation action. The operation is relatively simple and does not require complicated tools, which reduces the technical difficulty of installing the mining hose and the product has strong applicability.

[0028] Furthermore, the spiral inclination angle of the hose support structure 2 ranges from 84° to 88°, preferably 86°. A larger spiral inclination angle can increase the stability and load-bearing capacity of the hose support structure 2, making it more suitable for withstanding larger forces and torques. The 86° spiral inclination angle design can provide a better self-locking effect, avoiding the torque force generated in complex operating environments from causing the hose connection to loosen on its own, thereby improving the reliability of the hose connection.

[0029] Furthermore, the hose support structure 2 is made of rigid polyvinyl chloride, which has good corrosion resistance and can resist corrosion from various chemical substances. It is suitable for use in mining hoses in harsh environments. Rigid polyvinyl chloride has good wear resistance, which makes the hose support structure 2 less susceptible to wear when transporting materials. The service life of the hose support structure 2 can be extended to ensure that the hose support structure 2 is not easily worn during use and affects the support for the hose body 1, causing the hose to be deflated, thereby affecting the transportation of materials.

[0030] Furthermore, the hose support structure 2 is designed to have a circular cross-section. The circular cross-section design allows the hose support structure 2 to be more evenly stressed, reduces the possibility of stress concentration, and improves the stability and carrying capacity of the hose support structure 2 to ensure that the hose body 1 is always in a maximum conveying capacity state when conveying materials.

[0031] Furthermore, the outer layer 3 of the hose is provided with a connecting flat groove 31 to enable the hose to be better connected to the screw-in sealing joint 4. The planar design of the connecting flat groove 31, on the one hand, allows the thread to be more easily inserted and rotated, thereby making the installation process simpler; on the other hand, the flat groove reduces the contact area of ​​the thread, so that the wear between the threads can be reduced, thereby extending the service life of the thread of the mating connector.

[0032] Furthermore, the screw-in sealing joint 4 is provided with a threaded structure 41 that cooperates with the hose support structure 2 to achieve a detachable connection between the screw-in sealing joint 4 and the hose. Such a design allows the hose support structure 2 and the screw-in sealing joint 4 to be threadedly connected and then be locked and sealed to ensure the reliability and sealing of the connection and facilitate disassembly.

[0033] Furthermore, the outer layer 3 of the hose is made of soft polyvinyl chloride and wrapped and connected to the hose support structure 2. The outer layer 3 of the hose is made of soft polyvinyl chloride. On the one hand, soft polyvinyl chloride has good corrosion resistance, can effectively resist the erosion of the atmosphere, water and chemicals to the outer layer 3 of the hose, adapt to a variety of working environments, and thus extend the service life of the hose; on the other hand, soft polyvinyl chloride has a certain flexibility, can reduce the damage caused by external impact, increase the durability of the structure and the softness of the mining hose; at the same time, the soft polyvinyl chloride used in the utility model is added with conductive fillers or static dissipators and has antistatic properties, which can eliminate static charges accumulated during contact or friction, and reduce the risks in the process of conveying materials. Such a design can achieve that after the outer layer 3 of the hose is wrapped and connected to the hose support structure 2, the mining hose as a whole is easy to bend, adjust and install, thereby reducing the difficulty of outdoor operation installation of the hose and making the angle easy to adjust and install.

[0034] Furthermore, the hose body 1, hose support structure 2, and hose outer layer 3 are of one-piece molding design. The one-piece molding design, on the one hand, can provide a more secure connection, so that the mining hose can withstand higher pressures, avoiding the loosening or leakage problems that are prone to occur at the connections of ordinary hoses, thereby improving the safety of material transportation; on the other hand, through the one-piece molding design, the connection between the mining hose and the screw-in sealing joint 4 can be achieved through the threaded connection of the hose support structure 2, and there is no need to use bolts and nuts for connection reinforcement, which simplifies the connection and installation of the mining hose, thereby reducing the process and time during the installation process and improving work efficiency.
