## Abstract

Arrangement for mounting slides between a rock drilling machine and a carriage or the like mounted slideably with respect to the feeding beam of the drifting machine. In the arrangement, slide flames are formed by an integral body having a groove for a slide made as an integral body. The groove and the slide are such in cross section that the slide can be inserted into the slide frame only in its longitudinal direction.

## Claims

### Claim 1

In a rock drilling machine including a longitudinally arranged feeding beam, a mounting arrangement between the longitudinally arranged feeding beam and at least one component slidable along said feeding beam, the arrangement comprising a pair of opposed slide frames mounted to said component along opposite sides thereof, said opposed slide flames having mutually facing grooves formed therein, each groove having at least two adjacent surfaces oriented at a predetermined angle; a slide member secured within each of said grooves, each slide member having at least two exterior surfaces engaged with said at least two adjacent surfaces of a respective one of said grooves, each slide member and respective one of said grooves also having cooperating attachment surfaces which expand in a direction away from said feeding beam such that said slide members are insertable within said slide frames only in a longitudinal direction of the feeding beam; wherein said feeding beam is provided with angled slide surfaces along opposite side edges thereof, and wherein said slide members each have a groove facing said feeding beam and in surface engagement with said angled slide surfaces along the opposite side edges of said feeding beam.

### Claim 2 (depends on 1)

The arrangement according to claim 1, wherein each slide frame is attached to the component by bolts extending in a transverse direction relative to the feeding beam, mounting holes for the bolts extending at least partly through the groove of the slide frame, and wherein the slide members have notches at the mounting holes of the bolts in parallel therewith such that the slide members are fixed immovable with respect to the slide frame when the mounting bolts are in position.

### Claim 3 (depends on 2)

The arrangement according to claim 2, wherein the slide frames and the slide members are symmetrical in cross-section.

### Claim 4 (depends on 2)

The arrangement according to claim 2, wherein the slide members are substantially equal in length to the slide frames.

### Claim 5 (depends on 1)

The arrangement according to claim 1, wherein the slide frames and the slide members are symmetrical in cross-section.

### Claim 6 (depends on 1)

The arrangement according to claim 1, wherein the slide members are substantially equal in length to the slide frames.
