The invention discloses a unit frame for an
assembly frame of a fully-mechanized
coal mining hydraulic support frame. Slide ways are arranged at two sides of a flat car, an inner sleeve square tube stand column and an outer sleeve square tube stand column are connected with slide blocks in a hinged mode, a
hydraulic cylinder is arranged in each square tube stand column, a slide wheel is connected with the upper end of each
hydraulic cylinder, a lifting
rope winds on each slide wheel, support top hydraulic cylinders are respectively connected above the square tube stand columns, a car plate rotating device is arranged in the middle of a car plate, operation rails which are matched with a narrow gauge railway in a
coal mine underground roadway are arranged above the car plate, and the direction of the operation rails is perpendicular to the length direction of the square tube stand columns. According to the unit frame for the
assembly frame of the fully-mechanized
coal mining hydraulic support frame, the two square tube stand columns are respectively hinged on the slide blocks arranged on the slide rails which are at two sides of the flat car, the square tube stand columns on the flat car can be folded, an inner square tube and an outer square tube are arranged on the square tube stand columns and are extensible, and the car plate rotating device is arranged in the middle of the car plate. The unit frame for the
assembly frame of the fully-mechanized
coal mining hydraulic support frame is very convenient in assembly, disassembly and transportation. Due to the fact that the support top
hydraulic cylinder is connected with the upper end of the square tube stand columns, after the assembly frame of the fully-mechanized
coal mining hydraulic support frame is assembled, the stability of the device is good.
