DRILL WAGON FOR DRILLING EXCAVATION AND ROCKBOLT HOLES

摘要

1. An apparatus for boring in rock, ore or the like, for advance heading or tunnel construction, having a movable, articulated carriage (1), with raisable and lowerable supports (4), which apparatus comprises a plurality of boring heads (9, 16, 17) with rotatable brackets (8, 10, 11), the bore arms of which are constructed to be raisable and lowerable, and where appropriate rotatable and/or telescopically collapsible, and support a boring mounting (22) with a rotary percussion motor and a feeding device in an articulated manner, and are supplied hydraulically, characterized in that a boring head with a bracket (8), which comprises a shorter and/or telescopically collapsible mounting (22) than the other boring heads, is arranged between two others on the carriage (1) and is drivable so as to move in the direction of advance (a) with its bracket (8) along a displacement path (6) and is arranged parallel to the floor, and in addition two adjacent boring heads (16, 17) are drivable so as to be movable in the direction of advance (a) with their brackets (10, 11 along a displacement path (5, 7) in each case, the centrally arranged displacement path extending further forward than the two adjacent ones.
