Description

Technical Field

[0001] This utility model relates to the field of hydraulic hose technology, and in particular to a corrosion-resistant hydraulic hose. Background Technology

[0002] Hydraulic hoses play a vital role in modern industry. As a key component connecting various parts of a hydraulic system, they bear the crucial responsibility of transmitting hydraulic power. They consist of an inner rubber layer, a reinforcing layer, and an outer rubber layer, each with a specific function. The inner rubber layer, in direct contact with the hydraulic oil, must possess excellent oil resistance and sealing properties to ensure smooth and leak-free flow of hydraulic oil within the hose. The reinforcing layer, typically made of braided steel wire or fiber, provides the hose with strong compressive and tensile strength, enabling it to withstand the high pressures of the system. The outer rubber layer protects the reinforcing layer and resists external environmental corrosion, possessing properties such as wear resistance, aging resistance, and corrosion resistance. Hydraulic hoses are widely used in numerous fields, including construction machinery, automotive manufacturing, and aerospace. In construction machinery, they provide power to various hydraulic actuators, ensuring efficient equipment operation. In automotive manufacturing, hydraulic hoses are used in critical components such as braking and steering systems. Different applications place different performance requirements on hydraulic hoses, but reliability and stability are always essential.

[0003] For example, utility model CN220366062U discloses a high-strength hydraulic rubber hose, belonging to the field of rubber hose technology. It includes an inner rubber layer, a skeleton layer, and an outer rubber layer arranged sequentially from the inside out. The skeleton layer includes: arc-shaped members, evenly spaced along the circumference of the inner rubber layer, with adjacent arc-shaped members connected end-to-end; inclined support members, symmetrically arranged along the centerline of the arc-shaped member's cross-section, with both ends inclined outwards along the centerline of the arc-shaped member's cross-section; and vertical support members, vertically arranged along the centerline of the arc-shaped member's cross-section, with both ends of the vertical support member fixed to the inner surface of the arc-shaped member and the outer surface of the inner rubber layer, respectively. This utility model uses the skeleton layer to provide reverse support against the pressure and impact force transmitted from the inner rubber layer, thereby improving the overall strength of the rubber hose body. The first, second, and third grooves can absorb heat, generating a certain air pressure, thus improving the pressure resistance of the rubber hose body to a certain extent.

[0004] Similar to the above applications, the following shortcomings still exist:

[0005] The high temperatures generated by hydraulic oil during prolonged operation can damage the hose. Utility Model Content

[0006] This utility model discloses a corrosion-resistant hydraulic hose, which aims to solve the technical problem that the high temperature generated by hydraulic oil during long-term operation will damage the hose.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A corrosion-resistant hydraulic hose includes a steel pipe with a rubber tube fixedly connected to its inner wall. A first external threaded ring is fixedly connected to the bottom end of the steel pipe, and a second external threaded ring is fixedly connected to the top end of the steel pipe. A heat dissipation mechanism is provided on the inner wall of the first external threaded ring. The heat dissipation mechanism includes a support rod, which is fixedly connected to the inner wall of the first external threaded ring. A guide frame is fixedly connected to the end of the support rod, and a connecting block is fixedly connected to the inner wall of the guide frame. A sliding bearing is fixedly connected to the outer surface of the connecting block, and a connecting frame is fixedly connected to the outer ring of the sliding bearing. A rotating rod is fixedly connected to the upper surface of the connecting frame, and an agitator plate is fixedly connected to the outer surface of the rotating rod.

[0009] By installing steel pipes, heat can be conducted into the liquid inside the rubber tube. Utilizing the high thermal conductivity of steel, the heat dissipation of the liquid inside the rubber tube is accelerated. By installing a heat dissipation mechanism, the contact between the liquid and the inner wall of the rubber tube can be increased during liquid flow, thereby accelerating the heat dissipation of the liquid. By installing sliding bearings, the inner ring of the sliding bearing can be connected to the connecting block, and the outer ring can contact the connecting frame, thereby causing the connecting block and the connecting frame to rotate relative to each other.

[0010] In a preferred embodiment, the outer surface of the steel pipe is provided with several vent holes, which are evenly distributed. The inner wall of the rubber tube is provided with several strip grooves, which are also evenly distributed. The outer surface of the second external threaded ring is threadedly connected to a first internal threaded ring. The outer surface of the first internal threaded ring is fixedly connected to an outlet tank. The outer surface of the first external threaded ring is threadedly connected to a second internal threaded ring. The outer surface of the second internal threaded ring is fixedly connected to an inlet tank. A connecting pipe passes through the lower surface of the inlet tank, and a sealing ring is fixedly connected to the outer surface of the connecting pipe.

[0011] By setting vents, the rubber hose can better contact the outside air, accelerating the heat dissipation of the liquid. By setting grooves, the thickness of the inner wall of the rubber hose can be reduced, allowing the heat of the liquid to dissipate more quickly. By setting a first internal threaded ring, it can cooperate with a second external threaded ring, thus allowing the outlet tank to be connected to the top of the steel pipe. By setting a second internal threaded ring, it can cooperate with a first external threaded ring, thus allowing the inlet tank to be connected to the bottom of the steel pipe. By setting connecting pipes and sealing rings, the tightness of the connection between the inlet tank and the hose can be increased.

[0012] In a preferred embodiment, a propeller is fixedly connected to the outer surface of the rotating rod. The propeller is located below the agitator plate, and there are several agitator plates that are evenly distributed.

[0013] By setting up a propeller, the liquid can impact the propeller during the flow of the liquid, thereby causing the rotating rod to rotate. By setting up a stirring plate, the rotating rod can drive the stirring plate to rotate, thereby causing the liquid in the inner cavity of the steel pipe to rotate and come into contact with the inner wall of the rubber tube.

[0014] As can be seen from the above, a corrosion-resistant hydraulic hose has the following improvements and advantages compared with the existing technology;

[0015] Firstly, by installing steel pipes, heat can be conducted into the liquid inside the rubber tube. Utilizing the high thermal conductivity of steel, the heat dissipation of the liquid inside the rubber tube can be accelerated.

[0016] Secondly, by setting up a heat dissipation mechanism, the contact between the liquid and the inner wall of the rubber tube can be increased during the liquid flow process, thereby accelerating the heat dissipation of the liquid. By setting up a sliding bearing, the inner ring of the sliding bearing can be connected to the connecting block, and the outer ring can be in contact with the connecting frame, thereby causing the connecting block and the connecting frame to rotate relative to each other.

A heat dissipation mechanism 6 is provided on the inner wall of the first external threaded ring 3. The heat dissipation mechanism 6 includes a support rod 61, which is fixedly connected to the inner wall of the first external threaded ring 3. A guide frame 62 is fixedly connected to the end of the support rod 61. A connecting block 63 is fixedly connected to the inner wall of the guide frame 62. A sliding bearing 64 is fixedly connected to the outer surface of the connecting block 63, and a connecting ring is fixedly connected to the outer ring of the sliding bearing 64. A frame 65 is connected to a rotating rod 66 on its upper surface. An agitator 68 is connected to the outer surface of the rotating rod 66. By setting a steel pipe 1, heat can be conducted into the liquid inside the rubber tube 4. Utilizing the high thermal conductivity of steel, the heat dissipation of the liquid inside the rubber tube 4 is accelerated. By setting a heat dissipation mechanism 6, the contact between the liquid and the inner wall of the rubber tube 4 is increased during liquid flow, thereby accelerating the heat dissipation of the liquid. By setting a sliding bearing 64, the inner ring of the sliding bearing 64 can be connected to the connecting block 63, and the outer ring can contact the connecting frame 65, thereby causing the connecting block 63 and the connecting frame 65 to rotate relative to each other.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the outer surface of the steel pipe 1 is provided with several vent holes 2, which are evenly distributed. By providing vent holes 2, the rubber tube 4 can better contact the outside air, accelerating the heat dissipation of the liquid. The inner wall of the rubber tube 4 is provided with several strip grooves 5, which are evenly distributed. By providing strip grooves 5, the thickness of the inner wall of the rubber tube 4 can be reduced, allowing the heat of the liquid to dissipate more quickly. The outer surface of the second external threaded ring 7 is threadedly connected to the first internal threaded ring 8, and the outer surface of the first internal threaded ring 8 is fixedly connected to the liquid outlet tank 9. By providing the first internal threaded ring 8, it can cooperate with the second external threaded ring 7, thereby allowing the liquid outlet tank 9 to be connected to the top of the steel pipe 1.

A connecting pipe passes through the lower surface of the liquid inlet tank 11.

[0029] 13. A sealing ring 12 is fixedly connected to the outer surface of the connecting pipe 13. By setting a second internal threaded ring 10, it can cooperate with the first external threaded ring 3, thereby connecting the liquid inlet tank 11 to the bottom end of the steel pipe 1. By setting the connecting pipe 13 and the sealing ring 12, the tightness of the connection between the liquid inlet tank 11 and the hose can be increased.

[0030] Reference Figure 1 and Figure 6 In a preferred embodiment, a propeller 67 is fixedly connected to the outer surface of the rotating rod 66. The propeller 67 is located below the agitator plate 68. By setting the propeller 67, it can be impacted during the liquid flow, thereby causing the rotating rod 66 to rotate. There are several agitator plates 68, and the agitator plates 68 are evenly distributed. By setting the agitator plates 68, the rotating rod 66 can drive the agitator plates 68 to rotate, thereby causing the liquid in the inner cavity of the steel pipe 1 to rotate and contact the inner wall of the rubber tube 4.

[0031] Working principle: When the liquid flows in the inner cavity of the steel pipe 1, it is guided by the guide frame 62 and flows to the propeller 67, which causes the rotating rod 66 to rotate and the stirring plate 68 to rotate. Finally, the liquid in the inner cavity of the steel pipe 1 comes into contact with the inner wall of the rubber tube 4. Under the action of the strong thermal conductivity of the steel pipe 1, the heat is dissipated into the air, and the liquid is finally cooled.
