Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0029] The method for monitoring the hydraulic system of the fully mechanized mining face of the present invention collects the liquid supply volume of the hydraulic support, and collects the outlet pressure of the pump station, the inlet and outlet pressure of the inlet and filter station, the pressure of the inlet pipeline, the pressure of the column, the pressure of the side protection, and the return pipeline Pressure and pressure at the inlet and outlet of the liquid return filter station; the above-mentioned collected information is transmitted to the monitoring host of the working face, and the monitoring host of the working face displays the received information, and the staff make corresponding adjustments and investigations according to the displayed information.

[0030] The first m...

Abstract

The invention provides a fully mechanized coal mining face hydraulic system monitoring method for comprehensively monitoring the liquid supply capacity and quality of a working surface to provide morecomprehensive and accurate working surface hydraulic system working conditions to workers so as to achieve better mastering. The method comprises the steps of: acquisition of the hydraulic bracket action liquid supply quantity; acquisition of the pump station outlet pressure, the liquid inlet filter station access port pressure, the liquid inlet pipeline pressure, the stand column pressure, the protection upper pressure, the liquid return pipeline pressure and the liquid return filter station access port pressure; transfer of the acquired information to a working surface monitoring main machine; displaying of the received information by the working surface monitoring main machine; and corresponding adjustment and investigation by workers according to the displayed information.

Description

technical field [0001] The invention belongs to the technical field of working face hydraulic systems, in particular to a method for monitoring the hydraulic system of a fully mechanized mining face. Background technique [0002] The automatic follow-up technology of the hydraulic support can be summarized as: through real-time collection of the position of the coal machine, judge and determine the automatic movement of the hydraulic support within a specific point or range, and complete the unmanned operation of the hydraulic support and the automatic follow-up of the machine. In the process of automatic follow-up, the regularity of the hydraulic support movement is improved, but the flexibility of the support movement is reduced compared with the manual operation. However, some potential information in the manual operation, such as column back pressure, pipeline pressure, etc., cannot be obtained. Feedback to the operator, there may be potential safety hazards, etc. Stabl...
