ACTUATING MEMBER OF MINING MACHINE Russian patent published in 2001 - IPC

Abstract RU 2167291 C1

FIELD: mining. SUBSTANCE: actuating member has frame, reducing gear with drive, boom, beams trapezoidal in shape and installed in reducing gear guides and secured by wedges, hydraulic cylinders of telescopic member connecting frame with reducing gear. Each trapezoidal beam has trunnion located perpendicular to beam plane running over large side of trapezium. At least two beams are installed on each side of frame for motion along axis of trunnion and rotation round it. Mounted coaxially with beam trunnions are hydraulic cylinders for moving of beams. Body of hydraulic cylinders are fixed to frame and their rods are engageable with beam trunnions. EFFECT: higher efficiency of actuating member operation and extended field of its application. 3 dwg
