Embodiment Construction

[0041] figure 1 A possible rock drilling unit 1 is shown which can be connected by means of a boom 2 to a movable carriage of a rock drilling rig (which is not shown). The rock drilling unit 1 may comprise a feed beam 3 and a rock drilling machine 4 supported on the feed beam 3 by means of a carriage 5 . The rock drilling machine 4 can be moved in the drilling direction A and in the reverse direction B on the feed beam 3 by means of a feed device 6 connected to the carriage 5 . The rock drilling machine 4 comprises at the front end of the rock drilling machine 4 a shank 7 for connecting a drilling tool 8 . Drilling tool 8 may include one or more drill rods and a drill bit 9 at a distal end of drilling tool 8 . The rock drilling machine 4 also comprises a rotation device 10 for rotating the R shank 7 and the drilling tool 8 connected to the shank 7 . The rock drilling machine 4 is also provided with a percussion device 11 comprising a percussion element, such as a reciprocat...

Abstract

The invention relates to an arrangement in a rock drilling machine and to a method of mounting the same. The rock drilling machine (4) comprises a gear module (13) and a percussion module (15), which are arranged on a same axial line (17). The modules are pressed towards each other by means of several first connecting means (27) and several second connecting means (30). The connecting means generate first axial connecting forces (F1) and second axial connecting forces (F2) which receive axial operational forces of the rock drilling machine. The second connecting means also fasten the rock drilling machine to a carriage (5) provided with support surfaces (28).

Description

technical field [0001] The invention relates to an arrangement comprising a rock drilling rig mounted on a carriage supportable to a rock drilling rig feed beam. The rock drilling machine comprises a transmission module and a percussion module, the modules being arranged on the same axis and connected to each other by means of connecting means. [0002] The invention also relates to a method of installing a rock drilling rig. [0003] The field of the invention is defined more particularly in the preambles of the independent claims. Background technique [0004] In mines and other workplaces, rock drilling rigs are used to drill boreholes into rock surfaces and into soil. The rock drilling machine comprises rotation means for rotating the drilling tool about its longitudinal axis during drilling. The rock drilling machine also includes a percussion device for generating a percussion pulse to the drilling tool. The rock drilling rig is typically connected to a carriage su...
