Roadway U-type steel support performance test system and test method

Abstract

The invention discloses a roadway U-type steel support performance test system and test method. The system comprises a roadway support frame platform and an intelligent control test system. The roadway support frame platform comprises a ring force bearing frame, a hydraulic jack, a pressure sensor, a built-in displacement sensor, a force transmission rod, a jack fixing device and a support constraint device. The intelligent control test system comprises a distributed load remote pressure regulating system, a pump station, a pipeline system and an all-digital electro-hydraulic computer controlsystem (including software system). The roadway support frame platform and the intelligent control test system are connected through the built-in displacement sensor, the pressure sensor, a data transmission connection line and an oil pressure pipeline in a bridging way. According to the roadway U-type steel support performance test system and test method, the test accuracy can be enhanced, the workload of test operation can be reduced and the test process and result analysis are enabled to be more intelligent.

Description

technical field [0001] The invention relates to a roadway U-shaped steel support performance test system, in particular to a test test system and a test method for simulating field U-shaped steel support force performance test measurement and analysis. Background technique [0002] With the continuous increase of coal mining depth, the effect of mine pressure is significant, and the deformation and damage of roadway surrounding rock are obvious, which puts forward higher requirements for 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 this problem. The structure of the bracket itself and the mechanic...

Problems solved by technology

The current roadway support test bench was designed and developed earlier. Due to the limitation of the scientific and technological level at that time, the measurement and control system and test methods of the designed support test bench were relatively backward, and its loading method and technical parameters could no longer meet the performance of the current roadway support. testing requirements
