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.
Description
Technical field [0001] The invention relates to a device used for the installation and withdrawal of a complete set of coal mining equipment, in particular to a unit frame of a hydraulic support assembly frame for assembling and disassembling a hydraulic support. Background technique [0002] The fully mechanized hydraulic support is an important equipment in the complete set of fully mechanized coal mining equipment. The hydraulic support is placed in front of the fully mechanized mining work to form a coal mining space. The hydraulic support uses high-pressure liquid as the main power to complete the roof support of the working face, push the conveyor, support forward movement and goaf treatment. The hydraulic support is composed of multiple components connected. The hydraulic support is large and heavy. There are a large number of hydraulic supports in the comprehensive coal mining equipment. According to the size of the working face, there are generally more than one hundred ...
