Hydraulic support is a kind of equipment used to support and stabilize the working face of coal mines. The hydraulic system plays an important role. High-pressure hose is an important component in the hydraulic system. It is used to transport hydraulic oil or hydraulic fluid and withstand the high pressure generated in the system.

[0003] Application number: CN201711332019.6, discloses a high-pressure hose. During use, liquid (the liquid can be cooling water) is injected from the water inlet at one end of the high-pressure hose, and the liquid passes through the cavity structure and is discharged from the water outlet at the other end of the high-pressure hose, thereby taking away the high temperature and achieving cooling of the high-pressure hose. In addition, the cavity structure of the present invention is located between the middle rubber layer and the inner rubber layer, the second braided layer and the third braided layer are located in the annular cavity, the second braided layer and the third braided layer are supported by support bars, and the first braided layer is coated on the outer wall of the middle rubber layer, thereby improving the tensile strength and toughness of the present invention, and the outer wall of the outer rubber layer is coated with a fireproof layer, thereby improving the fireproof performance of the present invention;
