20000kN大倾角液压支架检测技术及装备研究

针对目前大倾角液压支架检测技术及装备落后于大倾角液压支架发展水平的现状，开发研制了大倾角液压支架主体结构、旋转系统、液压系统和测控系统，解决了煤层倾角在60°以上的液压支架防倒防滑试验、在倾斜状态下进行复合外加载测试和检测装备无级调高等技术难题，检测装备旋转角度为±90°、均布载荷20000kN、额定垂直外载11000kN、额定水平外载6000kN、额定侧向外载2000kN，台面尺寸7200mm×6000mm。

Research on detection technology and equipment of 2 0000kN hydraulic support with large inclination

In view of the current situation that the detection technology and equipment of hydraulic support with large inclination is behind the development level of hydraulic support with large inclination. This paper developed the hydraulic support with large inclination, including main structure, rotary system, hydraulic system and test system, the technical problems of anti-down and anti-skid test of hydraulic support with coal seam inclination which is above 60 degrees、composite external loading test under inclined state and stepless adjustment of detection equipment’s height were solved. The testing equipment has a rotating angle of ±90°, average distributed load of 20 000kN, rated vertical external load of 11 000kN, rated horizontal external load of 6 000kN, rated lateral external load of 2 000kN, and table size of 7 200mm x 6 000mm.
