摘　　要：为了满足液压支架检测检验和科学试验的要求,解决液压支架试验台垂直外加载试验技术和试验平台高度调整级差过大及自动控制等技术难题,研究了液压支架垂直外加载和平台调高技术,解决了大缸径、重载多缸同步、双层差级调高等关键技术;并成功应用于30 MN液压支架试验台,有效减小了最小调高档距,扩大了试验范围,提高了试验精度。External vertical loading and height adjustment technology were studied, which met the requirements of the hydraulic powered support test research and solved problem of external loading test technology used by hydraulic powered support experimental platform. The big diameter and heavy loading multi-cylinder synchronization control and double difference level height adjustment technologies were solved. The technologies were successfully applied in powered support experimental platform of 30 MN,effectively reduced the most minor of high-grade pitch. That expanded the test range and improved the test precision.
