发明名称 Arrangement for controlling percussive rock drilling
摘要 A method and a storage device including a software product for controlling percussive rock drilling, and further a rock drilling rig to which the method is applied. The rotation resistance is monitored, the aim being to keep it below a desired reference value. To adjust the rotation resistance, successive control actions may be carried out, such as decreasing the feed force, decreasing the percussion power and stopping the feed. Control actions are started once a limit set for the control has been exceeded. At least one limit is a time limit determining the time difference between two successive control functions.
