摘　　要：为单体液压支柱三用阀试验设计一套自动装卸机构。通过一套减速机在计算机控制下实现三用阀的自动装卸。利用弹簧和丝杠补偿三用阀的2个螺纹副的螺距差,为三用阀试验设计液压控制系统,为实现自动控制三用阀的装卸,设计电气控制系统。用Pro/E对装卸机构进行三维建模并导入ANSYS仿真软件,利用ANSYS对其进行静力学分析并建立装卸机构的整体应力和位移云图。分析结果表明装卸机构的强度和变形量符合设计要求。通过外协加工和购买所需的零部件建立试验台样机,并且经过长期试验与测试证明样机对三用阀的装卸具有很高的成功率。We develop a set of automatic loading/unloading mechanism （ALUM） for testing the three-use valves of hydraulic single prop. The automation loading and unloading of three-use valve is realized by a set of computer-controlled reducer. The moving difference of two screws in the three-use valves is compensated by a spring and a leading screw. The hydraulic control system is designed for testing the three-use valves. The electric control system is designed to realize the automatic control of the loading and unloading mechanism. A three-dimensional model of loading and unloading mechanism is built by the software Pro/E for ALUM and imported to the software ANSYS. The ALUM whole displacement cloud and the stress cloud are built by ANSYS. The static analysis results show that the strength of the structure and the deformation can achieve the design requirements. The prototype test rig is built by out processing and purchasing required components. The prototype test rig has a high success rate to load and unload the three-use valves by long-term experiments and tests.
