Description

Technical Field

[0001] This utility model relates to the field of high-pressure hose technology, and in particular to a high-strength wear-resistant high-pressure hose. Background Technology

[0002] High-pressure hoses are used in hydraulic systems for conveying petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, and water) at certain pressures and temperatures in mine hydraulic supports, oilfield development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems in various industrial sectors.

[0003] Currently, existing high-pressure hoses require a certain length of pipe for use, and when bending occurs during actual use, it is difficult to maintain the internal shape, which may lead to the risk of liquid blockage or even explosion. Therefore, this application provides a high-strength wear-resistant high-pressure hose to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-strength, wear-resistant, high-pressure hose to solve the problem that existing high-pressure hoses are prone to bending during use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A high-strength, wear-resistant, high-pressure hose includes: a hose body; a plurality of support rings disposed on the surface of the hose body; a support strip disposed between two adjacent support rings, the support strip being spiral-shaped; a plurality of chambers disposed within the support rings; a thin tube disposed between two adjacent chambers for communication between the two chambers; a piston slidably disposed within the chambers; a spiral groove disposed within the support rings and communicating with one end of the chambers; and a nickel-titanium alloy wire disposed within the spiral groove, one end of the nickel-titanium alloy wire being connected to the piston.

[0007] Preferably, the nickel-titanium alloy wire is spiral-shaped.

[0008] Preferably, the chamber is filled with hydraulic oil.

[0009] Preferably, when the hose body bends, the piston is pushed along the chamber by the nickel-titanium alloy wire to generate a force in the opposite direction to the bending of the hose body, so as to resist the bending deformation of the hose body.

[0010] Preferably, the hose body includes: an inner rubber layer, a transition layer, a reinforcing layer, an outer rubber layer, and an elastic layer.

[0011] Preferably, the outer adhesive layer contains microcapsules.

[0012] Preferably, the transition layer is composed of a nanomaterial coating or a high-performance polymer film.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects:

[0014] In the above solution, the support strip provides overall radial support force to prevent the hose from becoming smaller due to excessive bending, thus avoiding blockage. The support ring further limits the degree of local bending of the hose, ensuring the stability of the hose's internal shape in all aspects. Attached Figure Description

Detailed Implementation

[0020] The high-strength, wear-resistant, high-pressure hose provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art can also use other alternative methods to implement them; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0021] like Figure 1 - Figure 3As shown, an embodiment of this utility model provides a high-strength, wear-resistant, high-pressure hose, comprising: a hose body 1; a plurality of support rings 2 disposed on the surface of the hose body 1; a support strip 3 disposed between two adjacent support rings 2, the support strip 3 being spiral-shaped; a plurality of chambers 22 disposed within the support rings 2; a thin tube 21 disposed between two adjacent chambers 22 for communication between the two chambers 22; a piston 23 slidably disposed within the chambers 22; a spiral groove 24 disposed within the support rings 2 and connected to one end of the chambers 22; and a nickel-titanium alloy wire 25 disposed within the spiral groove 24, one end of the nickel-titanium alloy wire 25 being connected to the piston 23.

[0022] By setting the support bar 3, which is made of high-strength, corrosion-resistant stainless steel, it can provide overall radial support for the hose and form a stable support frame with the support ring 2, ensuring the stability of the hose's internal shape in all aspects.

[0023] The nickel-titanium alloy wire 25 is spiral-shaped. The nickel-titanium alloy wire 25 has a good shape memory effect. When the hose is bent, the spiral nickel-titanium alloy wire 25 will be stretched or compressed and deformed. Due to its shape memory characteristics, the nickel-titanium alloy wire 25 will try to return to its original spiral shape. This restoring force can be utilized more effectively than a straight arrangement.

[0024] The chamber 22 is filled with hydraulic oil. The hydraulic oil has good fluidity and incompressibility. When the restoring force generated by the bending of the hose by the nickel-titanium alloy wire 25 pushes the piston 23 to move in the chamber 22, the hydraulic oil can quickly and evenly transmit the thrust of the piston 23 to each connected chamber 22. According to Pascal's principle, in a closed hydraulic system, the pressure can be transmitted in all directions without changing its magnitude.

[0025] When the hose body 1 bends, the nickel-titanium alloy wire 25 pushes the piston 23 to move along the chamber 22, generating a force in the opposite direction to the bending of the hose body 1, thus resisting the bending deformation of the hose body 1. This force can directly act on the bent part of the hose, offsetting part of the bending force. This allows the hose to maintain its original shape to a certain extent, and the internal diameter will not decrease due to excessive bending, ensuring that the hydraulic oil can flow smoothly in the hose and avoiding blockages that could affect the normal operation of the equipment.

[0026] The hose body 1 includes: an inner rubber layer 14, a transition layer 15, a reinforcing layer 13, an outer rubber layer 12, and an elastic layer 11. By setting the elastic layer 11, materials with high elasticity, aging resistance, wear resistance, and good flexibility can be selected, such as natural rubber, nitrile rubber, or polyurethane elastomer, which mainly play a role in buffering and shock absorption, while improving the impact resistance and flexibility of the hose.

[0027] The outer adhesive layer 12 contains microcapsules. By setting the microcapsules to contain a repair agent, when the outer adhesive layer 12 is damaged by wear, scratches or other factors during use, resulting in tiny cracks, the microcapsules will rupture, and the repair agent inside will flow out.

[0028] The transition layer 15 is composed of a nanomaterial coating or a high-performance polymer film. By setting the transition layer 15, the adhesion between the layers can be effectively improved. Due to their extremely small size and high specific surface area, nanomaterials can form a tighter physical and chemical bond with the adjacent layer materials; while the high-performance polymer film, with its flexibility and good adhesion, enhances the connection strength between the layers.

[0029] The technical solution provided by this utility model, when the hose body 1 is bent, the nickel-titanium alloy wire 25 is stretched or compressed and deformed. It attempts to restore its original shape by virtue of its shape memory characteristics, thereby pushing the piston 23 to move in the chamber 22. The chamber 22 is filled with hydraulic oil and is interconnected by thin tubes 21. According to Pascal's principle, the movement of the piston 23 causes the hydraulic oil to flow between the chambers 22 and transmit pressure evenly, generating a balanced and large force in the opposite direction of the bending of the hose body 1, effectively resisting the bending deformation of the hose body 1 and maintaining the normal shape of the internal channel of the hose body 1.

[0030] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
