Method and arrangment for mounting bolts in a tunnel wall

An arrangement for mounting bolts in a tunnel wall comprising a frame, first and second turntables on the frame, a bolting device, and a control unit,

• the control unit being arranged to receive bolt mounting reference data, and being arranged to instruct a drill rig to bore bore holes in accordance with said bolt mounting reference data,
• the control unit being arranged to store actual data representing the actual positions of bore holes having been bored in the tunnel wall by the drill rig, and
• the control unit being arranged to instruct the bolting device to mount bolts in the bore holes based on the stored actual data and the bolt mounting reference data, further comprising,
• the control unit being arranged to store configurations of the drill rig when the drill rig is boring the bore holes in the tunnel wall, and
• the control unit being arranged to transform the configurations of the drill rig into configurations for the bolting device, the configurations of the drill rig and for the bolting device comprising configurations of actuators arranged to actuate parts of the drill rig and the bolting device,
• wherein said configurations comprise positions of the first and the second turntable on the frame, and
• wherein said bolting device is arranged on said first turntable and said drill rig is arranged on said second turntable, and said first and second turntable are arranged to move along said frame.

An arrangement for mounting bolts in a tunnel wall comprising:

• a frame having an axis;
• first and second turntables arranged on the frame and movable along the frame in a direction along the axis;
• a bolting device arranged on the first turntable;
• a drill rig arranged on the second turntable;
• and
• a control unit arranged to receive bolt mounting reference data and being arranged to instruct the drill rig to bore bore holes in accordance with said bolt mounting reference data,
• wherein the control unit is arranged to store actual data representing the actual positions of bore holes having been bored in the tunnel wall by the drill rig,
• wherein the control unit is arranged to instruct the bolting device to mount bolts in the bore holes based on the stored actual data and the bolt mounting reference data,
• wherein the control unit is arranged to store configurations of the drill rig when the drill rig is boring the bore holes in the tunnel wall,
• wherein the control unit is arranged to transform the configurations of the drill rig into configurations for the bolting device, the configurations of the drill rig and for the bolting device comprising configurations of actuators arranged to actuate parts of the drill rig and the bolting device, and
• wherein said configurations comprise positions of the first and the second turntable on the frame.
