Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic hoses, in particular to air tightness detection equipment for hydraulic hose production. Background Art

[0002] Hydraulic hose, also known as rubber-plastic hose, is a new type of hose used to transport petroleum-based and water-based liquids (such as emulsions, oil-water emulsions, water) and other liquids with a certain pressure and temperature. Hydraulic hoses are mainly used in mine hydraulic supports and oil field development. They are suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanization and automation hydraulic systems of various industrial departments. According to the publication number CN220366062U, a high-strength hydraulic rubber hose is disclosed, which belongs to the technical field of rubber hoses, including an inner rubber layer, a skeleton layer and an outer rubber layer arranged in sequence from the inside to the outside. The skeleton layer includes: arc-shaped parts, which are arranged at equal intervals along the circumferential direction of the inner rubber layer, and the two adjacent arc-shaped parts are connected end to end; inclined support parts, which are symmetrically arranged along the midline position of the arc-shaped cross section, and the two ends thereof are inclined outward along the midline position of the arc-shaped cross section; vertical support parts, which are vertically arranged along the midline position of the arc-shaped cross section, and the two ends on the cross section of the vertical support parts are respectively fixed to the inner surface of the arc-shaped part and the outer surface of the inner rubber layer. The utility model reversely supports the pressure and impact force transmitted from the inner rubber layer through the skeleton layer, thereby improving the overall strength of the rubber tube body, and can absorb heat through the first trough body, the second trough body and the third trough body, thereby generating a certain air pressure, thereby improving the pressure resistance of the rubber tube body to a certain extent. However, the hydraulic hose needs to be tested for air tightness after production, and conventionally, the hydraulic hose is manually placed on water for observation. If there are bubbles, the air tightness is not good. However, some hydraulic hoses are too long to be tested in sections, and long-term holding causes a lot of burden on both ends. In addition, the test bench for placing hydraulic hoses of different specifications cannot be placed, affecting the test efficiency. Therefore, it is urgent to design an air tightness test device for hydraulic hose production to solve the above problems. Utility Model Content
