Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-pressure hose assembly pressure testing, in particular to a high-pressure hose assembly pressure testing bench tooling. Background Art
[0002] High-pressure hose assemblies are commonly used as auxiliary devices in hydraulic and pneumatic systems. They consist of high-pressure steel wire braided or spiral-wound hose and metal connectors crimped together using crimping equipment. They are used to connect various hydraulic components in hydraulic and pneumatic systems. They typically consist of a liquid-resistant synthetic rubber inner layer, a middle layer, a steel wire reinforcement layer, and a weather-resistant synthetic rubber cover. They are primarily used for power transmission or transporting high-pressure media such as water, gas, and oil to ensure fluid circulation and transfer energy. They are primarily used in mine hydraulic supports and oilfield production, and are suitable for conveying oil-based liquids (such as mineral oil, soluble oil, hydraulic oil, fuel oil, and lubricating oil), water-based liquids (such as emulsions, oil-water emulsions, and water), gases, and other liquid transmissions at specific pressures and temperatures in mechanized and automated hydraulic systems across various industrial sectors.
[0003] Existing high-pressure hoses need to be pressure tested before use to prevent the hose from bursting due to insufficient pressure after installation. During the test, since the high-pressure hoses are of different lengths and the test fixtures are of a fixed length, it is easy to cause the high-pressure hose test to be divided into multiple sections, causing inconvenience.
[0004] As disclosed in Chinese patent CN212539940U, a fixing fixture for a pressure test bench of a high-pressure hose assembly is provided. An internal thread is provided on the inner circular wall surface of the inner hole, and a side column is provided in the inner hole. The side column is a cylindrical structure, and an external thread is provided on the outer circular wall surface of the side column. The side column is threadedly connected to the inner hole. A pressure plate is fixedly installed on the side wall surfaces of the two side columns close to each other. The pressure plate is a cylindrical structure, and a side groove is provided on the side wall surfaces of the two pressure plates close to each other. The side groove is an arc groove. By pulling the two support plates closer to each other or away from each other, the distance between the two support plates is increased or decreased, the hose is placed in the rotating groove, and the side column is rotated so that the side columns move closer to each other, the side column drives the pressure plate to move, and the pressure plate squeezes the hose and fixes it. At the same time, the rotating column is rotated, the rotating column drives the clamping column to rotate, the rotating column moves downward to drive the clamping column to move, the clamping column drives the pressure groove to move, and the pressure groove squeezes the hose and fixes it.
[0005] However, the device has a poor sealing effect on the connector of the high-pressure hose assembly, which easily causes leakage itself, resulting in a significant reduction in the reliability and accuracy of the pressure test data of the high-pressure hose assembly.
