Rotary device for large-dip-angle hydraulic support test and working method thereof

The invention provides a rotary device for a large-dip-angle hydraulic support test. The rotary device comprises a box type supporting beam located on the ground, two sets of guiding support devices arranged on the two sides of the box type supporting beam correspondingly, driving devices arranged on bosses in the middle of the guiding support devices, a safe clamping device fixed to the upper portion of the middle of the box type supporting beam, and rolling rings arranged on the left and right sides of a fixed hydraulic support test table correspondingly, wherein the rolling rings are borneon arc surfaces constructed by the guiding support devices and the driving devices, supported by a plurality of guiding wheels in the guiding support devices and driven to rotate by external gears inthe driving devices. When the rolling rings rotate to a preset regulated angle, three-in-one reducers in the driving devices are used for braking the rolling rings and the safe clamping device is usedfor clamping and fixing th
