Device for handling drill string components and rock drill rig

1. A handling device for handling drill string components in a rock drill rig which includes a rotator device being arranged for rotation and driving of a drill string component and being supported movable to and fro on a feed beam, the handling device comprising:

a drill string introducing unit configured to introduce drill string components into, and respectively remove drill string components from a drill string position of the rock drill rig,

a guiding beam arranged to extend laterally from the feed beam while forming an angle thereto, and which includes a longitudinal guide,

a gripper shuttle drivingly displaceable along the longitudinal guide, wherein the gripper shuttle includes a pivotally arranged guiding gripper for gripping a first end region of a drill string component, a second end region of which been arranged to be in engagement with a lifting plug, and

a drive motor arranged on the gripper shuttle configured to drive a drive wheel for co-operation with a drive track on the guiding beam, wherein the drive wheel is disengageable to allow essentially free movement of the gripper shuttle along the longitudinal guide.

2. A handling device according to claim 1 , wherein the drive wheel is a wheel acting against an essentially planar drive track.

3. A handling device according to claim 2 , wherein a contact pressure of the drive wheel against the drive track is adjustable.

4. A handling device according to claim 3 , further comprising:

a holder configured to support the drive wheel; and

a power unit configured to move the drive wheel with respect to a body of the gripper shuttle.

5. A handling device according to claim 1 , wherein the drive wheel is disengageable by being positioned out of engagement with said drive track.

6. A handling device according to claim 1 , wherein the longitudinal guide includes guiding strips arranged lengthwise on the guiding beam and facing different directions sideways, and wherein the gripper shuttle includes a guide configured to cooperate with the guiding strips.

7. A handling device according to claim 1 , wherein the guiding gripper is positioned on an arm which is pivotal with respect to a main portion of the gripper shuttle.

8. A handling device according to claim 7 , wherein the pivotal arm is pivotal between a first position for gripping a drill string component in the drill string position and a second position for gripping a drill string component in a delivering position.

9. A handling device according to claim 8 , wherein the first position is an adjustable position.

10. A handling device according to claim 1 , wherein the guiding gripper is adjustable for adaption to different sized drill string components.

11. A handling device according to claim 1 , wherein the guiding beam at an end is attachable in the region of the feed beam.

12. A handling device according to claim 11 , wherein the guiding beam is attachable pivotal around a first pivot axis in connection with said feed beam.

13. A handling device according to claim 11 , further comprising:

a gripping unit arranged to engage an end portion of a first drill component respectively an end portion of a second drill string component.

14. A handling device according to claim 1 , wherein the guiding beam has linear extension.

15. A rock drill rig, comprising:

a rotator device for rotation and driving a drill string and being supported movable to and fro by a feed beam, and

a handling device comprising

a drill string introducing unit configured to introduce drill string components into, and respectively remove drill string components from, a drill string position of the rock drill rig,

a guiding beam arranged to extend laterally from the feed beam while forming an angle thereto, and which includes a longitudinal guide,

a gripper shuttle drivingly displaceable along the longitudinal guide, wherein the gripper shuttle includes a pivotally arranged guiding gripper for gripping a first end region of a drill string component, a second end region of which been arranged to be in engagement with a lifting plug, and

a drive motor arranged on the gripper shuttle configured to drive a drive wheel for co-operation with a drive track on the guiding beam, wherein the drive wheel is disengageable to allow essentially free movement of the gripper shuttle along the longitudinal guide.
