Problems solved by technology

However, during long downhill drives, such a large amount of electrical energy is generated that it cannot all be used to charge the battery
Thus, the electric system of a rock drilling rig has limited ability to control the electrical power generated, which can make efficient downhill driving more difficult

Embodiment Construction

[0030] figure 1 A possible rock drilling rig 1 is shown having a movable carrier 2 with one or more booms 3 a , 3 b equipped with a drilling unit 4 . The drilling unit 4 may comprise a feed beam 5 with a rock drilling machine 6 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 may comprise flushing means. The boom 3 a shown in the figure and the drilling unit 4 arranged therein are intended to be used for drilling a borehole in the pit face 11 of a tunnel or in a corresponding drilling site. Alternatively, the boom and the drilling unit thereon may be designed for drilling fan-shaped boreholes in the roof and walls of the rock cavern. Furthermore, the rock drilling machine 1 may comprise a boom 3 b provided with an anchoring device 12 which also comprises the rock drilling machi...

Abstract

The invention relates to a rock drilling rig and a method for downhill driving of a rock drilling rig. The rock drilling rig comprises electric drive equipment, the drive motor of which serves as a primary brake in long-term downhill driving. The drive motor thus converts kinetic energy into electric energy, with which an energy storage is charged. To consume surplus electric energy, a hydraulic system or a compressed air system is turned on. A hydraulic pump and a compressor (54) are driven by an electric motor.

Description

technical field [0001] The invention relates to a rock drilling rig comprising a boom provided with a rock drilling machine and a pressure medium system having an actuator connected thereto. The rock drilling rig is moved by means of a drive device without an internal combustion engine, said drive device comprising at least one electric drive motor and a power transmission member between the drive motor and a traction wheel. In transfer driving, the electrical energy to be used can be charged into an energy store, which is included in the electric system. During long-term downhill drives, the drive motor acts as a generator and service brake and controls the electrical energy generated to charge the accumulator. [0002] Furthermore, the invention relates to a method for downhill driving of a rock drilling rig. [0003] The field of the invention is described in more detail in the preambles of the independent claims of the present application. Background technique [0004...
