The utility model relates to a self-moving hydraulic bracket used for coalmine short-wall exploitation, which comprises two groups of self-moving hydraulic side frames; one group of self-moving hydraulic middle frames or two groups of self-moving hydraulic middle frames are connected between the two groups of self-moving hydraulic side frames, and the lower ends of front parts of two groups of self-moving hydraulic side frames and one group of self-moving hydraulic middle frames or two groups of self-moving middle frames are connected with a stepping beam; two groups of self-moving hydraulic side frames, one group of self-moving hydraulic middle frames and the stepping beam which is connected with the self-moving hydraulic middle frames form a from of three-frame in one-group; and the two groups of self-moving hydraulic side frames, two groups of self-moving hydraulic middle frame and the stepping beam which is connected with the self-moving hydraulic middle frames form a form of four-frame in one-group. The utility model has the advantages that the structure is simple, the weight is light, the operation is convenient, the operation is safe and reliable, the own system can be established, the self-moving can be achieved, the processes of pushing coal, dismantling, mounting and maintaining are convenient, and a tunnel roof can be effectively supported.
