APPARATUS FOR CUTTING ROPES Russian patent published in 1994 - IPC

FIELD: cutting equipment. SUBSTANCE: at energizing the hydraulic drive 6 the feed mechanism 5 is being switched from a neutral position to its working position, the car 8 begins to move; and the rope is being subjected to torsion and bending deformation. In dependance upon physical and mechanical properties of the rope 1 a pressure in a hydraulic manifold of the hydraulic drive 36 of the mechanism 9 for rotating the rope will be increase to maximum value, and a signal is being fed to the hydraulic cylinder 31, controlling the variable-yield hydraulic pump 23 in order to decrease its efficiency and respectively a feed of the friction saw 7 and vice versa. The car 8, being moved with the aid of the slider 34, provides a stroke of the handle 34 of a throttling hydraulic distributor 16, upon a cut of the rope being deepened, decreases a flow rate of working fluid, being fed to the hydraulic motor 15 of the hydraulic drive 36 of the mechanism for rotating the rope. The cutting of the rope had been over, the throttling hydraulic distributor 16 of the hydraulic drive 36 of the mechanism for rotating the rope is being switched to its neutral position. EFFECT: enhanced serviceability. 3 cl, 3 dwg
