Embodiment Construction

[0037] figure 1A rock drilling rig 1 for face drilling during tunneling is shown. The rock drilling rig 1 comprises a movable transport carrier 2 and one or more drilling booms 3 connected to the transport carrier 2 . When the drilling rig comprises a plurality of drilling booms, the drilling rig is often referred to as a drilling jumbo. The drilling boom 3 comprises a base boom part BB which is an elongated structure and whose first end BB1 is movably connected to a transport carrier. At the distal second end BB2 of the base cantilever portion is the feed beam assembly FBA. The feed beam assembly FBA may comprise a feed beam 5 and a rock drilling machine 6 supported on the feed beam 5 . The rock drilling machine 6 may comprise a shank at the front end of the rock drilling machine 6 for connecting the tool 7 . The feed beam assembly FBA is connected to the second end BB2 of the base boom section by means of a front joint arrangement 8 (may also be referred to as a wrist jo...

Abstract

The present invention relates to a drilling boom and rock drilling rig. The drilling boom (3) comprises a basic boom part (BB) a distal end of which is provided with a front joint assembly (8) of wrist. The wrist connects a feed beam assembly (FBA) to the basic boom part. The wrist has three joints, which are a roll-over joint (15), a feed tilt joint (16) and a feed swing joint (17). Order of thejoints of the wrist is optimized when the joints are in the mentioned order. The rock drilling rig (1) is provided with one or more such drilling booms provided with face drilling units or bolting heads.

Description

technical field [0001] The invention relates to a drilling cantilever of rock drilling equipment. The drilling boom is provided with a feed beam assembly comprising a rock drilling rig for drilling blast holes or bolting holes into the rock surface. The boom includes a number of joints that allow positioning of the rock drilling rig to the planned drilling location. [0002] The invention also relates to a rock drilling rig. [0003] The field of the invention is defined more particularly in the preambles of the independent claims. Background technique [0004] In mining and other workplaces, different types of rock drilling equipment are used. The rock drilling equipment is provided with one or more booms, the rock drilling unit being arranged at the distal end of the booms. The rock drilling unit comprises a feed beam along which the rock drilling rig is configured to move during the drilling process. The drilling boom includes a number of joints to allow the rock dri...
