Abstract
The utility model relates to the technical field of mine pit cage falling prevention equipment, in particular to a cage safety brake drive device for a mine lifting falling prevention device. A cage falling prevention product used in a mine pit at present is a falling prevention product aiming to that a main rope of a cage snaps; when an accident occurs on a winch, because the cage is still hung by the main rope when falling down, the falling prevention device cannot exert the falling prevention function to lead an accident to occur. The cage safety brake drive device for the mine lifting falling prevention device is used matching with the cage of the falling prevention device; and comprises a main box body, a pair matching battery jar box and an electric oil pump box. Motion ends of oil cylinders in box bodies at both sides of an oil storage box on the main box body are connected with a power arm end of a lever through pin shafts, and a hook at the head of a resistance arm of the lever is pressed on a pin shaft of the falling prevention device in a locking way. When the pin shaft of the falling prevention device is pressed down, a grasper of the falling prevention device can be caused to lock a guide rope to cause the cage to brake, thereby a cage falling accident is avoided. The oil storage box is provided with a limit switch. When the limit switch is pressed, a circuit is cut off, and the lever stop working.
