摘要: 针对液压支架手动换向阀耐久性试验存在测试周期长、效率低、无法实现自动测试的问题，设计了一种液压支架手动换向阀耐久性试验自动化装置。该装置基于液压油缸往复运动，结合使用被试手动换向阀手柄推拉专用工装，带动被试手动换向阀手柄左右摆动，达到自动换向目的。同时，利用测控系统软件控制装置启动、换向、采集压力、判断计数等动作，从而实现被试手动换向阀耐久性试验的自动化测试。实际应用结果表明:该装置具有结构简单、加载速度可调、试验效率高的特点，耐久性试验周期由原来的165.6 h缩短至31.2 h。Abstract: For problems of long test cycle, low efficiency and unable to realize automatic test in durability test of manual reversing valve of hydraulic support, an automation device for durability test of manual reversing valve of hydraulic support was designed. The device is based on reciprocating movement of hydraulic cylinder, and uses push-pull special tool of the manual reversing valve handle to drive handle of the manual reversing valve to swing from left to right to achieve purpose of automatic reversing. At the same time, software of measurement and control system is used to control actions of starting, reversing, collecting pressure, judging and counting of the device, so as to realize automatic test of durability test of the manual reversing valve. The practical application results show that the device has characteristics of simple structure, adjustable loading speed and high test efficiency, and durability test cycle is shortened from 165.6 h to 31.2 h.
