Hydraulic support is an important equipment of coal mine production. Its design and manufacture level affects the safe production and economic benefits of coal mine directly. This paper took ZT6500/19.5/34 hydraulic support as an example. First, three dimensions solid models of the type simplified hydraulic support prototype and its 1:5 model were constructed by three dimensions construction model software SolidWorks. Then, three dimensions solid models were led in ANSYS software. Finally, the strength test of the type hydraulic support prototype and its 1:5 model were proceeded under base torsion working condition by ANSYS software. The relevant total displacement distribution rule and equivalent stress distribution rule of the type simplified hydraulic support prototype and its 1:5 model were found. The proportion relation of total displacement and equivalent stress between the type simplified hydraulic support prototype and its 1:5 model were confirmed. This provides an effective way of design and research hydraulic support.

Abstract In recent years, the coal mine intelligent development process has constantly advanced, putting forward higher requirements for monitoring mining equipment data. Sensor technology suitable for the special underground environment has also been developing. Hydraulic support is a key piece of equipment in fully mechanized coal mining. Monitoring the hydraulic support position and attitude has been an important part of coal mine intelligent development. In the present paper, a new oil cylinder displacement sensor was proposed. The oil cylinder translational motion was transformed into the magnet rotary motion via the motion conversion mechanism. The magnet angle was calculated by utilizing the single-chip microcomputer, and the oil cylinder expansion and contraction were calculated via the filtering algorithm. Results showed that the sensor accuracy could reach 0.5 mm.
