This invention relates to the field of hydraulic support installation technology, and more particularly to an installation device and method for installing the side guard plate of the top beam of a hydraulic support. The invention includes a horizontally arranged placement platform and a telescopic frame. The telescopic frame includes multiple sets of telescopic components, which are arranged parallel to each other and spaced apart along the length of the placement platform. Each set of telescopic components includes a fixed cylinder, a push-pull rod, a first hydraulic cylinder, and two vertically arranged clamping columns, all arranged along the width of the placement platform. The fixed cylinder is fixedly installed on the bottom wall of the placement platform. The push-pull rod is inserted into the fixed cylinder, and the opposite ends of the push-pull rod and the fixed cylinder are respectively fixedly connected to the two clamping columns. The first hydraulic cylinder is fixedly installed inside the fixed cylinder. By setting multiple sets of telescopic components, multiple first hydraulic cylinders can drive multiple clamping columns to move synchronously inward, thereby applying a stable and uniform compressive force to the side guard plate and overcoming the elastic force of the compression spring on the guide rod of the side guard plate.

The utility model discloses a photovoltaic panel support buckle which is characterized by comprising a connecting piece which is in a bent shape and used for being connected with an external fixing piece, connecting lugs are arranged on the two sides of the end, away from the end connected with the external fixing piece, of the connecting piece respectively, a handle is rotationally connected between the two connecting lugs, and the connecting piece is connected with the external fixing piece. A hooking piece is rotationally connected in the handle, the connecting point of the hooking piece and the handle and the connecting point of the handle and the connecting lug are not located on the same straight line, by means of the method, secondary fixing is achieved through cooperation of the hooking piece and the pressing piece, the contact area of the pressing piece and the photovoltaic panel is large, the stress surface is large, and therefore stable extrusion force is provided, and the photovoltaic panel can be fixed conveniently. The photovoltaic panel is firmly fixed on the channel steel, the photovoltaic panel is prevented from being turned over by the wind when the wind is strong, through a handle mode, locking and unlocking operation is simple, maintenance is convenient, manual work can be reduced through a buckling mode, professional tools do not need to be carried, and meanwhile installation is convenient and fast, and cost is low.
