Description

Adjustable hydraulic hose assembly for high pressure

The present invention relates to an adjustable hydraulic hose assembly for high pressure, and more particularly, to a hydraulic hose assembly which is formed to be capable of adjusting a predetermined length, and can be installed efficiently, and has improved airtightness.

The hydraulic (high pressure) hose allows fluid such as hydraulic oil or lubricant to move, and should not be damaged by fluid pressure. Hydraulic hoses are used differently depending on the pressure, and manufacturing methods are also different.

In general, the inner structure of the hydraulic hose is formed of a synthetic rubber material that is oil-resistant and water-resistant, so that it is not damaged even when the fluid moves, and the outer surface is formed of a material having high oil resistance, weather resistance and wear resistance.

Hydraulic hoses are widely used as fluid hydraulic hoses such as mineral hydraulic oils, aqueous hydraulic oils, flame retardant hydraulic oils, and hydrocarbon-based synthetic lubricating oils.

The hydraulic hose manufactured by additionally stacking the inner and outer surfaces, and the reinforcing layer structure, can withstand even if the internal pressure is high pressure and is safely manufactured from external impact. The reinforcing layer structure is generally formed by inserting a plurality of steel cores, and as a result, the hydraulic hose has high strength and is not easily bent by external force.

The hydraulic pressure in the hydraulic hose is transmitted by a force applied to a part of the fluid in a closed state, and the applied pressure should not exceed the pressure specification of the hydraulic hose.

To connect the hydraulic hose with an external structure, a hose coupling is formed at the end of the hydraulic hose to deliver hydraulic pressure, and a hydraulic hose assembly is formed. The hydraulic hose and the hose coupling may be integrally formed or detachable. It may be.

In addition, the hose coupling is preferably formed of a metal material to withstand high pressure.

In general, a place where a high pressure hydraulic hose is used is frequently used in industries where hydraulic machines are utilized, and is mainly used to transfer power by converting hydraulic energy into mechanical energy (ex) high pressure press).

In addition, since a hydraulic device is used when carrying out a structural test to evaluate the stability of the structure, a hydraulic hose for high pressure is used, and installation and separation are repeatedly performed according to the form of the structural test.

Since the hydraulic hose used in the structural test determines the length according to the installation location, unlike the hydraulic hose used in general industries, the length must be cut to suit the location.

At this time, if there is a slight error in length or direction depending on the manufacture of the hydraulic hose, there is a difficulty in connecting and installing the hydraulic hose. As described above, the hydraulic hose is manufactured to be hard and not easily bendable to withstand the pressure of the fluid, and there is a case where the reinforcement layer structure formed by inserting a plurality of steel cores is further stacked to produce hydraulic pressure even if an error occurs in length or direction. It is not easy to change the curvature of the hose, which causes problems in installation.

Structural testing is carried out by installing hydraulic components around complex and various types of structures, such as test bodies or test fixtures, and is affected by surrounding objects and limited locations.

Therefore, when the hydraulic hose is installed in contact with a nearby object, there is a fear that the outer surface of the hose is bent due to unnecessary external force from the object, and when the fatigue becomes higher, the hydraulic hose is damaged and the hydraulic oil moving along the hydraulic hose There is a concern that it may leak outside.

Therefore, the above-mentioned problem can be solved if the length of the hydraulic hose is formed to be able to compensate for the length error or to avoid the structure.

The first packing part 230 is positioned between the first front part and the adjustment part 120.

The inner diameter of the first rear portion is formed larger than the inner diameter of the first front portion, so that the second fixing portion 220 can be fitted. In other words, the second fixing part 220 is fitted between the adjusting part 120 and the first rear part of the first fixing part 210.

Similarly, when the side of the second fixing part 220 is divided in half and the front part is assumed to be the second front part and the rear part is the second rear part, the inner diameter of the second front part is formed to be the same as the outer diameter of the adjusting part 120, , The inner diameter of the second rear portion is formed to be the same as the outer diameter of the insertion portion 321.

As described above, the inner diameter of the insertion portion 321 is formed to be the same as the outer diameter of the stopper 130, so that the insertion portion 321 is inserted between the rear surface of the second fixing portion 220 and the stopper 130, and the adjusting portion Between the outer surface of the 120 and the inner surface of the insertion portion 321, a gap is formed by the height of the step formed by the combination of the adjusting portion 120 and the stopper 130.
