Design and analysis of group attitude detection device for hydraulic support

Hydraulic support is the key supporting equipment in coal mining operation, and its good working condition is the prerequisite for improving coal mining efficiency and ensuring environmental safety. The geological conditions of large dip, thick and extra-thick coalseams are more complicated, and the support is more difficult, so the support stability of hydraulic support must be more reliable. In order to clearly perceive the change of the working attitude of the hydraulic support group, the relative structure model of the hydraulic support was studied, and three different structure detection devices were designed, namely, the position and posture detection device of the parallel cable sensor, the direction Angle detection device and the two-dimensional rocker detection device. Finally, after analyzing the detection accuracy, manufacturing difficulty, reliability and solving speed of the three kinds of detection devices, the combination of the two-dimensional rocker detection device and wire sensor is determined as the best detection device.
