High-pressure rubber hose detection equipment for mining

Abstract

The invention discloses high-pressure rubber hose assembly detection equipment for mining. The equipment is used for detecting the high pressure resistance and gas tightness of a high-pressure rubber hose assembly, wherein the high-pressure rubber hose assembly comprises a high-pressure rubber hose and a connector connected to two ends of the high-pressure rubber hose; the connector comprises a primary valve block and a secondary valve block; a plurality of mounting holes matched with the connector are formed in the tops of the primary valve block and the secondary valve block; U-shaped clamping and inserting grooves corresponding to the same row of mounting holes are formed in side faces of the primary valve block and the secondary valve block; a first hydraulic cylinder is fixed beside the primary valve block; a piston rod of the first hydraulic cylinder extends to the primary valve block; a first push plate equivalent to the primary valve block in length is fixed at the front end of the piston rod of the first hydraulic cylinder; a plurality of clamping strips are fixed on the first push plate in parallel; every two adjacent clamping strips form a U-shaped clamping structure for fixing the connector. The high-pressure rubber hose assembly detection equipment for mining with the capacity of realizing batch production and adjustable water pressure is realized.

Description

technical field [0001] The invention belongs to the technical field of rubber hose detection, in particular to a mining high-pressure rubber hose assembly detection equipment. Background technique [0002] The rubber hose is made of multi-layer rubber, metal and non-metal through a special process. Because of the physical and chemical properties of the inner rubber layer, the effect of the pipeline conveying medium on the pipeline, such as friction, impact, corrosion, etc., is reduced. Moreover, the rubber hose has the characteristic of being bendable, so it has been widely used in the special working conditions of mine beneficiation and transportation. [0003] Mine high-pressure rubber hose, due to the high liquid pressure in the rubber hose, the working pressure of the hydraulic pump station is often above 30MPa, due to the instability and impact of the hydraulic pump, the high-pressure rubber hose will withstand great pressure Instantaneous pressure, if the high-pressur...

Problems solved by technology

[0003] Mine high-pressure rubber hose, due to the high liquid pressure in the rubber hose, the working pressure of the hydraulic pump station is often above 30MPa, due to the instability and impact of the hydraulic pump, the high-pressure rubber hose will withstand great pressure Instantaneous pressure, if the high-pressure rubber hose assembly has quality defects (pinholes, unstable dimensions) during production or the hose assembly is crimped incorrectly, it will cause pinhole damage to the hose assembly. People, pipe burst, head off, the high-pressure high-speed jet overflowing from the pinhole will pierce the skin and spray the fluid under the skin or cause partial amputation, and even cause the burst of the hose. During the rupture of the hose, the The high-pressure liquid will be ejected at a high speed, which may injure people in the area. After the hose assembly comes off, the whipping phenomenon of the high-pressure hose will cause serious injury to nearby personnel. Therefore, the high-pressure rubber hose Before leaving the factory, it needs to be tested for its high pressure resistance and air tightness to meet the requirements

However, at present, the detection of high pressure resistance and air tightness of high-pressure rubber hoses for mines is mainly carried out manually, which is time-consuming, labor-intensive, inefficient, and poses safety hazards to operators.
