MACHINE TO DRILL UPWARD HOLES |
摘要 |
mining and construction industries. SUBSTANCE: invention deals with directional boring of upward large- diameter holes in rocks of various hardness. Machine to drill upward large-diameter holes has driving actuator with rock-breaking tools, driving caterpillar trolleys and unit of their outward thrust in the form of cylinder mounted for interaction with link-and- lever mechanisms coupled to trolleys. Rock-breaking tools are mounted for interaction with springy members anchored on actuator. Unit of outward thrust is equipped with springs interacting with cylinder and link-and-level mechanisms, each carrying tie unit with mechanism changing its length. Rock-breaking tools can be connected to springy members. Machine can include separable hole reamers and laser finder system. EFFECT: diminished dynamic loads on drive of actuator, increased maneuverability and expanded field of application of machine. 3 cl, 4 dwg
