Technical Field

[0001] The utility model relates to the technical field of winding rubber hoses, in particular to a winding rubber hose used for a pilot pipe in the forklift industry. Background Art

[0002] In the forklift industry, the pilot tube winding hose is an important component. It is mainly used to transmit hydraulic fluid or gas to achieve the control of various functions of the forklift. In short, the pilot tube winding hose in the forklift industry is an important guarantee for the normal operation and efficient work of the forklift. By selecting high-quality products and conducting regular maintenance inspections, the stability and safety of the forklift can be ensured, and the work efficiency and service life can be improved.

[0003] The existing Chinese patent number: CN217272509U discloses a new type of wire-wound hose, which belongs to the field of wire-wound hose and includes a hose body. A left pipe head is arranged at the left end of the hose body, and a right pipe head is arranged at the right end of the hose body. The left end of the left pipe head is arranged with a threaded groove, and the right end of the right pipe head is arranged with a threaded ring. A wire ring is arranged inside the inner wall of the hose body, and a steel wire is arranged inside the inner wall of the hose body. The new type of wire-wound hose is provided with a left pipe head and a right pipe head at the left and right ends of the hose, and the left pipe head and the right pipe head are respectively provided with a threaded ring and a threaded groove, so that multiple hoses can be connected for use. At the same time, multiple wire rings and four steel wires are arranged inside the hose. The connection of multiple wire rings and steel wires has the effect of strengthening the structural strength of the hose, and the provision of spaced wire rings can ensure the toughness and bendability of the hose body, so that the hose can be bent, and the hose will not easily break, which is conducive to use.

[0004] Although the above-mentioned equipment will not easily have the problem of hose breakage, when the equipment is in use, if the pipeline breaks, if the crack is small, it will cause leakage, which will make it difficult for the staff to detect it, and safety hazards are likely to occur when the machine continues to be used. Utility Model Content

[0005] The utility model aims to solve the problem that the above-mentioned equipment cannot detect the ruptured part of the hose when in use, resulting in potential safety hazards when continued to use, and proposes a winding hose for the pilot tube in the forklift industry.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a spiral rubber hose for the pilot pipe in the forklift industry, comprising an inner rubber layer, the outer wall fixing sleeve of the inner rubber layer is provided with a reinforcing layer, the outer wall fixing sleeve of the reinforcing layer is provided with a middle rubber layer, firstly, the inner rubber layer is made of a special rubber material, which has good sealing, oil resistance and wear resistance, so as to ensure that the fluid will not leak during the transmission process, and resist the corrosive effect of the medium, thereby providing a good channel for the circulation of the liquid, and the outer wall fixing sleeve of the inner rubber layer is provided with a reinforcing layer, and the reinforcing layer is usually woven with a combination of steel wire and fiber textile, which can improve the strength and pressure resistance of the overall hose, and when in use, when the liquid in the pipeline circulates, the pipeline can maintain a higher pressure resistance and avoid the risk of rupture of the hose, and the middle rubber layer of the outer wall fixing sleeve, firstly, the middle rubber layer is firstly made of a special rubber material, such material has good elasticity and wear resistance, and it is installed in the middle area of ​​the hose to balance the stress between the layers of the hose and improve the overall structural strength and stability of the hose. The middle rubber layer can also increase the flexibility and wear resistance of the hose, making it suitable for use in various complex environments.

[0007] Preferably, the outer wall fixing sleeve of the middle rubber layer is provided with a protective layer. First, the protective layer is made of synthetic fibers such as nylon and polyester, which can resist erosion by various substances in the external environment, protect the internal structure of the hose from damage, and extend the service life of the pipeline.

[0008] Preferably, the outer wall of the protective layer is fixedly sleeved with a coating layer. First, during the manufacturing process, the coating layer needs to be produced according to the acidity and alkalinity of the liquid used inside the precursor tube. When the liquid required inside is acidic or alkaline, some pH indicators can be added during the production of the coating layer. When the hose finally ruptures, the liquid inside it contacts the coating layer, and a chemical reaction can occur with the indicator inside, causing the color of the coating layer to change, thereby reminding the operator to check and replace the hose in time to avoid potential safety hazards. In addition, a transparent protective layer is sleeved on the outermost end of the coating layer, which not only makes it easier for the staff to observe the coating layer, but also protects the hose inside the transparent protective layer to avoid erosion of the hose by the external environment.

[0009] Preferably, the thickness of the inner rubber layer is between 3mm-4.5mm, and the thickness of the reinforcement layer is between 2mm-4mm. Firstly, the thickness of the inner rubber layer is set to 3mm-4.5mm, and under its own characteristics, it can improve its resistance to the flowing liquid inside.

[0010] Preferably, the thickness of the middle rubber layer is between 1.5 mm and 3 mm, and the thickness of the protective layer is between 3.5 mm and 5 mm. The thickness of the middle rubber layer is smaller than that of other layers, so as to balance the layers in contact with each other.

[0011] Preferably, the thickness of the coating layer is between 0.5 mm and 1.5 mm, and the coating layer is relatively thin to avoid observation by external staff.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, through the action of a series of components, when the hydraulic fluid inside the hose ruptures and leaks, the liquid inside will leak to the location of the coating layer, and can react chemically with the inside of the coating layer, causing the color of the coating layer to change, thereby reminding the operator to check and replace the hose in time to avoid potential safety hazards.

[0014] 2. In the utility model, through the action of a series of components and the action of the various layers of raw materials inside the hose, the overall compression resistance of the hose can be improved, thereby extending the service life of the hose. BRIEF DESCRIPTION OF THE DRAWINGS

First, the coating layer 5 is arranged at the outermost end of the protective layer 4. First, during the manufacturing process, the coating layer 5 needs to be produced according to the acidity and alkalinity of the liquid used inside the precursor tube. When the liquid required inside is acidic or alkaline, some pH indicators can be added during the production of the coating layer 5. When the hose finally breaks, the liquid inside it contacts the coating layer 5, and a chemical reaction can occur with the indicator inside it, causing the color of the coating layer 5 to change, thereby reminding the operator to check and replace the hose in time to avoid potential safety hazards. In addition, a transparent protective layer is sleeved on the outermost end of the coating layer 5, which not only makes it easier for the staff to observe the coating layer 5, but also protects the hose inside the transparent protective layer to avoid the problem of erosion of the hose by the external environment.
