[0013] In order to facilitate those skilled in the art to understand the technical solution of the utility model, further description is now made with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model.

[0014] In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, it is apparent that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0015] like Figure 1 The figure shows the overall structure of the support bracket of the control main valve group for the hydraulic support of the utility model, which includes a fixed base 1, a horizontal top plate 2, a side guard plate 3 and an interlayer rotating support plate 4. A pair of side guard plates 3 are symmetrically arranged on the left and right sides of the fixed base 1, and a first connecting hole 31 is arranged on the top of the pair of side guard plates 3 for installing the top plate 2 to prevent gangue and coal slag from falling. A pair of limit plates 32 are arranged on the inner side of the upper side of the pair of side guard plates 3, and a rotating shaft 33 protruding inward is arranged at the center of the pair of limit plates 32. The two ends of the interlayer rotating support plate 4 are rotatably connected to the pair of limit plates 32 by setting a fixing hole 41 that is connected to the rotating shaft 33. A plurality of mounting holes 43 for matching the installation of the control main valve group are arranged on the interlayer rotating support plate 4, which are used to be bolted to the control main valve group. Limit holes 42 are arranged at both ends of the interlayer rotating support plate 4 near the fixing hole 41. A first elastic limiting column 34 and a second elastic limiting column 35 are respectively arranged at the front end and the upper end of the inner side of a pair of limiting plates 32. When the interlayer rotating support plate 4 is placed horizontally, it is clamped with the first elastic limiting column 34, and when it is rotated to be placed vertically, it is clamped with the second elastic limiting column 35. Therefore, the hydraulic support main valve group control support support designed by the utility model fixes the hydraulic support main valve group control on the interlayer rotating support plate, rotates to be placed vertically when in use, and is not easily hit by falling coal slag and gangue, thereby avoiding misoperation and improving the safety of use.

[0016] In specific implementation, the first elastic limiting column 34 and the second elastic limiting column 35 include a spring embedded in the limiting plate and a steel ball arranged on the top of the spring. When rotating to match the limiting hole 42, the steel ball is clamped into the limiting hole 42 by the elastic force. When driven by external force, the steel ball is compressed and deviates from the limiting hole 42.

[0017] The above embodiments are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
