Abstract

The utility model belongs to the technical field of hydraulic supports, and particularly relates to a hydraulic support limiting device for mining equipment, which comprises a console and a limiting box plate, an arc-shaped sliding groove is arranged on the periphery of the limiting box plate, a U-shaped block is fixedly mounted on the inner bottom wall of the console, and the U-shaped block is rotatably connected with a first control rod through a rotating shaft. A rectangular groove is formed in the upper end of the first control rod, an insertion rod is inserted into the inner wall of the rectangular groove, a second control rod is fixedly welded to the upper end of the insertion rod, and an elastic assembly is connected between the rectangular groove and the insertion rod; according to the utility model, the original mode of matching with a locking box is changed into the mode that one control rod is divided into two parts, and the elastic component and the limiting component are matched during the process, so that the whole body can directly press acting force on the control rod II to complete the rotation of the control rod, and the complexity caused by operation through the two parts is eliminated; therefore, the overall practicability is improved.
