Description

Technical Field

[0001] This utility model relates to the field of high-pressure hose technology, and specifically to a high-pressure hose with a wear indicator layer. Background Technology

[0002] High-pressure hoses are flexible pipes capable of transmitting high-pressure fluids. They are characterized by strong pressure resistance, good flexibility, and resistance to media corrosion, and are widely used in hydraulic systems, engineering machinery, petrochemicals, mining, and other fields. However, due to the diverse application locations of existing high-pressure hoses, some hoses are subjected to bending or frequent friction over long periods, leading to wear on the hose walls. Traditional high-pressure hoses have fixed internal and external materials, making it impossible to determine the specific degree of wear. Furthermore, the integrated design of existing high-pressure hoses requires replacement of the entire hose after wear occurs, reducing the effectiveness of the high-pressure hose and increasing hose consumption.

[0003] Therefore, we propose a high-pressure hose with a wear indicator layer to solve the above problems. Utility Model Content

[0004] In view of the problems existing in the high-pressure hoses with wear indicator layers, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a high-pressure hose with a wear indicator layer, which solves the problem that existing high-pressure hoses cannot effectively determine their wear level during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-pressure hose with a wear indicator layer includes multiple high-pressure hose bodies connected end to end. Each high-pressure hose body includes an inner tube, an outer tube, and a wear indicator tube, with the wear indicator tube disposed between the inner tube and the outer tube. The high-pressure hose body has a quick-change plug and a quick-change nozzle at both ends. A connecting tube is provided between the quick-change plug and the high-pressure hose body. A wrapping tube is fixed at the end of the connecting tube. A positioning component for limiting the position of the wrapping tube is provided between the wrapping tube and the high-pressure hose body.

[0007] Preferably, the connecting pipe is a telescopic corrugated pipe and is heat-fused to the quick-connect plug.

[0008] Preferably, the wrapping tube is a rubber tube and is interference-fitted with the outer wall of the outer tube.

[0009] Preferably, the positioning component includes a positioning block, the outer wall of the outer tube has a groove, the positioning block is disposed inside the groove, the wall of the wrapping tube has a limiting hole, and the upper end of the positioning block is disposed inside the limiting hole; The lower end of the positioning block is fixedly fitted with a sliding plate, and the inner wall of the groove has two symmetrically arranged sliding grooves through which the ends of the sliding plates slide. A spring is fixed between the inner wall of the sliding plate and the sliding groove.

[0010] Furthermore, the positioning block is a wedge-shaped block.

[0011] Preferably, the wall of the wear indicator tube is coated with an indicator paint.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model, through the inclusion of an inner tube, an outer tube, a wear indicator tube, a quick-change plug, and a quick-change spout, enables the high-pressure hose to be configured in a multi-segment combination. When the hose wears out, only the worn section of the hose needs to be replaced. At the same time, the wear indicator tube can effectively determine the degree of wear of the hose, thus improving the performance of the high-pressure hose. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model discloses a high-pressure hose with a wear indicator layer.

[0018] This utility model provides, for example Figure 1-4The high-pressure hose with wear indicator layer shown includes multiple high-pressure hose bodies 1 connected end to end. Each high-pressure hose body 1 includes an inner tube 2, an outer tube 3, and a wear indicator tube 4. The wear indicator tube 4 is located between the inner tube 2 and the outer tube 3, and the tube wall of the wear indicator tube 4 is coated with an indicator coating. The high-pressure hose body 1 is provided with a quick-change plug 5 and a quick-change spout 6 at both ends. A connecting pipe 7 is provided between the quick-change plug 5 and the high-pressure hose body 1. The connecting pipe 7 is a telescopic corrugated pipe and is heat-fused with the quick-change plug 5. A wrapping pipe 8 is fixedly provided at the end of the connecting pipe 7. The wrapping pipe 8 is a rubber tube and is interference-fitted with the outer wall of the outer tube 3.

[0019] To ensure the quick-connect plug is securely positioned, easy to replace, and allows for easy separation of multiple hose sections, such as... Figure 1 and Figure 3-4 As shown, a positioning component for limiting the position of the wrapping tube 8 is provided between the wrapping tube 8 and the high-pressure hose body 1. The positioning component includes a positioning block 9, which is a wedge-shaped block. A groove is provided on the outer wall of the outer tube 3, and the positioning block 9 is located inside the groove. A limit hole 10 is provided on the tube wall of the wrapping tube 8, and the upper end of the positioning block 9 is located inside the limit hole 10. A sliding plate 11 is fixedly inserted into the lower end of the positioning block 9. Two symmetrically arranged sliding grooves are provided on the inner wall of the groove, through which the ends of the sliding plates 11 slide. A spring 12 is fixed between the sliding plate 11 and the inner wall of the sliding groove.

[0020] Working principle: When using this high-pressure hose with wear indicator layer, multiple high-pressure hose bodies 1 are connected end to end to form a complete pipeline by using the quick-change plugs 5 and quick-change spouts 6 at both ends of the high-pressure hose body 1. During the connection process, the connecting pipe 7 between the quick-change plug 5 and the high-pressure hose body 1 is a telescopic corrugated pipe, which can adapt to a certain installation deviation. At the same time, it is easy to separate the quick-change plug 5 and quick-change spout 6 when disassembling. The wrapping tube 8 at the end of the connecting pipe 7 is a rubber tube, which will be press-fitted to the outer wall of the outer tube 3 to initially achieve sealing and fixation after connection. Meanwhile, under the elastic force of the spring 12, the positioning block 9 in the groove of the outer wall of the outer tube 3 will push the slide plate 11 to move the positioning block 9 upward, so that the upper end of the positioning block 9 is inserted into the limiting hole 10 of the wall of the wrapping tube 8. Since the positioning block 9 is a wedge-shaped block, it can further restrict the position of the wrapping tube 8, ensuring that the quick-change plug 5 and the high-pressure hose body 1 are stably connected, and avoiding loosening of the connection due to vibration and other factors during use. During the use of high-pressure hoses, the inner tube 2 is used to transport high-pressure fluid, and the outer tube 3 protects the internal structure, preventing external wear from directly affecting the inner tube 2. When the outer tube 3 wears down due to long-term bending and rubbing, as the wear of the outer tube 3 intensifies, the wear indicator tube 4 located between the inner tube 2 and the outer tube 3 will be exposed. Since the wall of the wear indicator tube 4 is coated with an indicator coating, the operator can visually judge the wear degree of the high-pressure hose. If the wear is severe and replacement is required, the quick-change plug 5 is separated from the high-pressure hose body 1, and the worn high-pressure hose body 1 is replaced separately. After replacement, it can be reassembled according to the above connection method and continued to be used.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
