  • In order to meet the study requirements of the hydraulic powered support test and to change to the present status of the hydraulic powered support dete ction technology and equipment behind the development level of the hydraulic powered support, the paper had a systematic study on the hydraulic powered support det ection technology and the test equipment, including the main structure, hydraulic control system and test system.With the multi-cylinder synchro control, vertical externa 1 loading, lateral external loading, side loading proof, double layer difference height adjustment and other key technology solved, the test device with sidewall protectio n, tail beam and pushing mechanism and the comprehensive hydraulic powered support test equipment with X-Y-Z three directional complex external loading function W ere successully researched and developed.The max loading capacity was 30 000 kN, the rated vertical external loading was 22 000 kN, the rated horizontal external lo ading was 6 600 kN, the rated lateral loading was 3 200 kN and the max test space was 8.0 mx4.0 mx7.6 m.According to the national standards of MT 312-2000, GB 25 974.1-2010 and EN 1804. 1-2002, different hydraulic powered supports could be detected and tested.
