AI Technical Summary

Problems solved by technology

The task is further complicated by the fact that the ground at the drilling site may be uneven and the drilling site may be in a narrow tunnel
Driving a known rock drilling rig into a drilling site is difficult because the drive equipment of the known rock drilling rig is very unsuitable for accurate positioning

Embodiment Construction

[0037] figure 1 Shown is a rock drilling rig 1 comprising a mobile carrier 2 provided with one or more drilling booms 3a, 3b equipped with drilling units 4. The drilling unit 4 may comprise a feed beam 5 provided 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 6 may comprise flushing means. The drilling boom 3 a shown in the figure and the drilling unit 4 arranged thereon are intended for drilling a borehole in the pit face 11 of a tunnel or in a corresponding drilling site. Alternatively, the drilling boom and the drilling unit thereon may be designed for drilling fan-shaped boreholes in the roof and walls of rock caverns. Furthermore, the rock drilling machine 1 can comprise a drilling boom 3 b provided with an anchoring device 12 likewise hav...

Abstract

The invention relates to method for positioning a rock drilling rig and to a rock drilling rig. The rock drilling rig (1) is moved using combustion-engine-free drive equipment (16) with an electric drive motor (M). The torque is transmitted from the drive motor to the traction wheels (19) over a mechanical anti-slip transmission connection (22). The ratio between the drive motor (M) rotation rate and the traction wheel rotation rate is kept constantly the same during positioning. The drive motor is not only used for moving but also for stopping.

Description

technical field [0001] The invention relates to a method for positioning a rock drilling rig. A rock drilling rig is driven to a drilling site for drilling. During positioning, the rock drilling rig is moved entirely by means of an electric drive without an internal combustion engine. The necessary rotational torque is generated by means of an electric drive motor controlled by a control device. The rotational torque is transferred from the drive motor to the drive wheels through a drive connection. [0002] The invention also relates to rock drilling rigs. [0003] The field of the invention is described in more detail in the preambles of the independent claims. Background technique [0004] In mines, rock drilling rigs are used to drill boreholes at planned drilling sites. When the borehole has been drilled, the mining vehicle is moved to the next drilling site for drilling a new drilling fan or face. In particular, in underground mines it is advantageous to perform ...
