Claims
- 1. An arrangement for replacing a drilling component in a rock drilling apparatus comprising:a carrier, a boom, the boom being maneuverably connected to the carrier, a drilling unit, the drilling unit being maneuverably connected to the boom for pivotable movement about a plurality of axes for driving the drilling unit to a drilling position, the drilling unit comprising at least a rock drill, a feeding beam and feeding means, at least one component magazine separate from the drilling unit for storing drilling components required in drilling and a changing unit for handling the drilling components between the component magazine and the drilling unit, and means for driving the drilling unit to a predefined position and location with respect to the component magazine for replacing a drilling component.
- 2. An arrangement as claimed in claim 1, wherein the changing unit is connected to the carrier.
- 3. An arrangement as claimed in claim 1, wherein the changing unit is arranged to turn relative to its turning joint between the component magazine and the drilling unit, and the changing unit comprises an arm capable of being lengthened or shortened, and a free end of the arm comprises a gripping device for gripping the drilling components.
- 4. An arrangement as claimed in claim 1, wherein a hold station is at an end of the feeding beam, the changing unit is connected to the drilling unit and the changing unit is arranged to handle the drilling components between the component magazine and the hold station.
- 5. An arrangement for replacing a drilling component in a rock drilling apparatus comprising:a carrier, a boom, the boom being maneuverably connected to the carrier, a drilling unit, the drilling unit being maneuverably connected to the boom, the drilling unit comprising at least a rock drill, a feeding beam and feeding means, at least one component magazine separate from the drilling unit for storing drilling components required in drilling and a changing unit for handling the drilling components between the component magazine and the drilling unit, and means for driving the drilling unit to a predefined position and location with respect to the component magazine for replacing a drilling component, wherein the changing unit is connected to the boom.
- 6. An arrangement for replacing a drilling component in a rock drilling apparatus comprising:a carrier, a boom, the boom being maneuverably connected to the carrier, a drilling unit, the drilling unit being maneuverably connected to the boom, the drilling unit comprising at least a rock drill, a feeding beam and feeding means, at least one component magazine separate from the drilling unit for storing drilling components required in drilling and a changing unit for handling the drilling components between the component magazine and the drilling unit, and means for driving the drilling unit to a predefined position and location with respect to the component magazine for replacing a drilling component, wherein the component magazine and the changing unit are connected to the boom, and a relative position of the component magazine, changing unit and drilling unit is independent of a position of the boom.
- 7. An arrangement as claimed in claim 6, wherein movements of the changing unit are mechanically restricted according to the relative position of the predefined replacement position of the drilling unit and the component magazine.
- 8. An arrangement for replacing a drilling component in a rock drilling apparatus comprising:a carrier, a boom, the boom being maneuverably connected to the carrier, a drilling unit, the drilling unit being maneuverably connected to the boom, the drilling unit comprising at least a rock drill, a feeding beam and feeding means, at least one component magazine separate from the drilling unit for storing drilling components required in drilling and a changing unit for handling the drilling components between the component magazine and the drilling unit, and means for driving the drilling unit to a predefined position and location with respect to the component magazine for replacing a drilling component, wherein the component magazine comprises a turnable body on a periphery of which protrusions are arranged for holding the drilling components.
- 9. An arrangement for replacing a drilling component in a rock drilling apparatus comprising:a carrier, a boom, the boom being maneuverably connected to the carrier, a drilling unit, the drilling unit being maneuverably connected to the boom, the drilling unit comprising at least a rock drill, a feeding beam and feeding means, at least one component magazine separate from the drilling unit for storing drilling components required in drilling and a changing unit for handling the drilling components between the component magazine and the drilling unit, and means for driving the drilling unit to a predefined position and location with respect to the component magazine for replacing a drilling component, wherein the boom comprises two beams longitudinal to the rock drilling apparatus at a distance from each other and the component magazine and the changing unit are arranged between the beams of the boom.
