Abstract
A rock drilling apparatus and method for controlling the orientation of a feed beam of a rock drilling apparatus including a carrier, a drilling boom attached at a first end to the carrier, a feed beam attached turnably to a second end of the drilling boom, a drilling unit attached movably along the feed beam, and a support attached to the feed beam for supporting the drilling boom on the ground. The orientation of the boom and feed beam are adjusted to compensate for the orientation change caused by driving the support onto the ground.
Claims12
A rock drilling apparatus comprising:
- a carrier;
- a drilling boom attached at a first end to the carrier;
- a feed beam attached turnably to a second end of the drilling boom;
- a drilling unit attached movably along the feed beam:
- a support attached to the feed beam for supporting the drilling boom on the ground;
- and
- an arrangement for controlling the orientation of the boom and feed beam, wherein the arrangement is configured, on the basis of parameters affecting the orientation, to define the orientation change caused by driving the support onto the ground, the apparatus being configured to automatically adjust the orientation of the boom and feed beam before applying drilling force to compensate for the orientation change caused by supporting the drilling boom onto the ground.
A method for controlling the orientation of a feed beam of a rock drilling apparatus comprising a carrier, a drilling boom attached at a first end to the carrier, a feed beam attached turnably to a second end of the drilling boom, a drilling unit attached movably along the feed beam, and a support attached to the feed beam for supporting the drilling boom on the ground, the method comprising the steps of:
- defining the orientation of the boom and feed beam;
- defining, on the basis of parameters affecting an orientation change, the orientation change caused by driving the support onto the ground;
- and
- adjusting automatically the orientation of the boom and feed beam to compensate for the orientation change before applying drilling force.
