Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is further described:

[0013] Such as figure 1 Shown is a block diagram of a high-precision fully automatic hydraulic servo control system. When testing the support on the test bench, the computer digital control system 1 outputs the loading parameters set in the experiment and the action signal of the control valve body to the hydraulic console 2, and the hydraulic console 2 controls the valve body action output to be stable through its own internal feedback system The pressure is given to the high-precision hydraulic jack 3, and the output force of the high-precision hydraulic jack 3 acts on the experimental object 4, so as to realize the experimental loading under the full digital control of the computer. The load sensor and displacement sensor installed on the experimental object collect the force, displacement and other signals of the experimental object in real time, and the signal is fed back...

Abstract

The invention discloses a high-precision full-automatic servo control system of a roadway support test stand. The high-precision full-automatic servo control system is composed of a computer digital control system, a performance detection system, a hydraulic control console, a high-precision hydraulic jack and the like, and is a complete set of mechanic-electric-hydraulic integrated high-technology system equipment. The high-precision full-automatic servo control system takes the high-precision hydraulic jack as an actuating mechanism, uses a signal monitoring system for feedback, adopts a static load servo valve, a flow valve and the hydraulic control console as core components, and realizes actual simulation of a control target under commands of the computer digital control system. The computer digital control system is of a 2-level distributed control structure, and is composed of an upper computer and a lower computer. The high-precision full-automatic servo control system improves the design of the roadway support test stand to be combined with modern electronic and computer science technologies, solves the problems that the equipped measuring and control system of the current roadway support test stand is lagged behind and the performance detection requirement of the current roadway support test stand cannot be satisfied, and is of great significance to the development of the roadway support test stand and the high-precision monitoring and detection of performance of roadway supports.

Description

technical field [0001] The invention relates to an automatic control system, in particular to a high-precision full-automatic servo control system for a roadway support test bench. Background technique [0002] With the development of the coal industry, the depth of coal mining continues to increase, coupled with the continuous improvement of the level of mechanized production and the requirements of high-yield and high-efficiency mines, the roadway support conditions are becoming more and more complex, and higher requirements are put forward for the roadway support technology. . The support technology based on bolts has played an important role in the control of surrounding rock in coal mine roadways, and solved a large number of engineering problems. However, under the condition of deep high stress, a single anchor (cable) support cannot solve this support problem, and the combined support technology of the anchor supporting bracket is an important technical way to solve ...
