Embodiment Construction

[0035] figure 1A possible rock drilling rig 1 is shown comprising a movable carrier 2 in which one or more booms 3a, 3b equipped with a rock drilling unit 4 are arranged. The drilling unit 4 may comprise a feed beam 5 , to which a rock drilling machine 6 is arranged movable on the feed beam 5 by means of a feed device 7 . The rock drilling machine 6 may comprise percussion means 8 for generating impact pulses on the tool 9 and rotation means 10 for rotating the tool 9 . Furthermore, the rock drilling machine 6 may comprise flushing means. The boom 3a shown in the figure and the drilling unit 4 arranged thereto are intended for drilling a borehole in a drilling face 11 of a tunnel or a corresponding drilling site. Alternatively, the boom and the drilling unit thereon can be designed for drilling fan-shaped boreholes in the roof and walls of the rock cavern. Furthermore, the rock drilling machine 1 comprises a boom 3 b provided with a bolt connection 12 , the boom 3 b also co...

Abstract

The invention relates to a rock drilling rig, a method for transfer drive of the rock drilling rig, and a speed controller. The rock drilling rig (1) comprises combustion-engine-free drive equipment (16) which includes a plurality of electric components (K) for implementation of the transfer drive. The control unit (C) of the rock drilling rig includes load monitoring (KV) which monitors the load of the components during the transfer drive. Load monitoring allows the electric driving system to be intentionally overloaded for a period of time limited in advance. A user interface of the control unit comprises a speed controller (50) whose control element (51) has a first control range (53), where operation takes place in the rated load range, and a second control range (54), where operation takes place in the overload range.

Description

technical field [0001] The invention relates to a rock drilling rig comprising a boom provided with a rock drilling machine so that drilling can thus be performed at a selected drilling site. The rock drilling rig also includes a drive without an internal combustion engine by which the rock drilling rig can be transferred between drilling sites. A drive arrangement for a rock drilling rig comprises at least one electric motor and an electric drive system, and also comprises a control unit comprising means for controlling the load of the electric drive system. In addition, the control unit includes a user interface with a speed controller. [0002] Furthermore, the invention relates to a method and a speed controller for a transfer drive of a rock drilling rig. [0003] The field of the invention is described in more detail in the preambles of the independent claims of this patent application. Background technique [0004] Rock drilling rigs are used in mines to drill bore...
