Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of the utility model protection.
Referring to shown in Fig. 1, a kind of rotary type hydraulic support, including pedestal 15, rotating seat is fixed on described pedestal 15 top
14, and described rotating seat 14 top is provided with firm banking 13；Described firm banking 13 top fixed support 11, and described support 11
Side is provided with hydraulic prop 2；Described hydraulic prop 2 surface is provided with hydraulic control one-way valve 4, is provided with push rod between described hydraulic prop 2
12, and described push rod 12 side is provided with and reels frame 5；Described frame 5 side that reels connects push unit 6, and described push unit 6 leads to
Cross nut 7 and be fixed on described firm banking 13 top surface；Described firm banking 13 connects caving shield 9 by described support 11, and
