Pressure measuring device self-carried by individual hydraulic prop

Abstract

The invention relates to a pressure measuring device self-carried by an individual hydraulic prop. According to the pressure measuring device disclosed by the invention, the phenomena that liquid in the prop is leaked and pressure in the prop is decreased when the pressure of the prop is itinerantly monitored can be radically avoided, the problem that a tri-purpose valve (2) is damaged due to frequent insertion of a hydraulic pressure gauge (1) can be radically solved, and the purpose that the pressure of the individual hydraulic prop is dynamically detected in a real-time manner is realized, so that the pressure measuring time is shortened. The invention aims to provide the pressure measuring device comprising a pressure stabilizing valve (4), a duct (3), and the hydraulic pressure gauge (1), wherein the duct (3) is connected to the tail end of the lower part of the hydraulic pressure gauge (1), and a thread is formed in the duct (3); the hydraulic pressure gauge (1) is a pressure measuring device connected to the spiral thread duct (3), and the measuring range of the hydraulic pressure gauge (1) is 0-60 MPa. The pressure measuring device disclosed by the invention is novel in structure and light in mass, and the dynamic pressure of the hydraulic prop can be well monitored in a real-time manner; real-time parameter support is provided for safe supporting and protecting; the labor cost for monitoring the hydraulic pressure gauge (1) is reduced; the monitoring efficiency of the hydraulic prop is improved. The pressure measuring device disclosed by the invention is an innovation for pressure measurement of the individual hydraulic prop, and has a good practical value and a good economic value.

Description

technical field [0001] The invention relates to the field of coal mine single hydraulic prop support, in particular to a self-contained pressure measuring device of a single hydraulic prop. Background technique [0002] The single hydraulic prop is an ideal supporting equipment and end support equipment for high-grade mechanization, general mining face and fully mechanized mining face; It has the advantages of light weight, large working stroke, high strength, and convenient use. It has been widely used in the support of mine working faces, providing good protection for mines and workers in safe production and work, and has a large application prospect. However, for the pressure measurement work of the traditional hydraulic prop, special inspection personnel need to be arranged, and the hand-held hydraulic gauge (1) is inserted on the three-purpose valve (2) for pressure measurement. This monitoring process takes a lot of time (generally 5-6 minutes / frame), and often resul...

However, for the pressure measurement work of the traditional hydraulic prop, special inspection personnel need to be arranged, and the hand-held hydraulic gauge (1) is inserted on the three-purpose valve (2) for pressure measurement

This monitoring process takes a lot of time (generally 5-6 minutes / frame), and often results in hydraulic oil leakage and damage to the three-way valve (2) due to frequent insertion of the hydraulic gauge (1)
