Hydraulic support for fully mechanized mining and caving face end

摘要

The invention relates to synthesizing discharging face end hydraulic support. Two of them are formed a set. It is made up of left support, right support, falling preventing jack, and hydraulic circuit. The left and right support are made up of three top beams, three bases, and three columns all of with are divided into front, middle, and back. The three top beams are hinged orderly. The front top beam is hinged to canopy guard front beam and its jack. The back top beam is hinged to caving shield. The three bases are hinged orderly. It is adopted front back joining among the bases. The front base is connected to loading mechanism. The falling preventing jack is hinged between the top beams and connecting rod. The distance between the front and middle columns, middle and back columns are respectively adapted to the distance that the width of the front back scraper conveyor plus forward lead step pitch. The left support base is set side jack. The invention can realize end head supporting mechanization, reduce manual labor, increase ahead speed. Its structure is simple; weight is light; the support moving is convenient.
