AI Technical Summary

Benefits of technology

The present solution provides the advantage of supplying fuel to a fuel-operated down-the-hole drill without having to feed fuel from outside the drill hole. This is difficult and can cause damage. By placing the fuel tank close to the drill, problems related to long fuel feed hoses and positioning can be avoided.

Problems solved by technology

In connection with fuel-operated down-the-hole drills, fuel feeding generally causes various problems.
Fuel feeding from a fuel tank to the drill is typically arranged by means of fuel feed hoses or other corresponding feed lines, which take up space and may become damaged under difficult operating conditions.

Embodiment Construction

[0033]FIG. 1 shows a rock drilling rig 1 that may comprise a movable carrier 2 provided with a drilling boom 3. The boom 3 is provided with a rock drilling unit 4 comprising a feed beam 5, a feed device 6 and a rotation unit 7. The rotation unit 7 may be supported to a carriage 8, or alternatively the rotation unit may comprise sliding parts or the like support members with which it is movably supported to the feed beam 5. The rotation unit 7 may be provided with drilling equipment 9 which may comprise one or more drilling tubes 10 connected to each other, and a drill bit 11 at the outermost end of the drilling equipment. The drilling unit 4 of FIG. 1 is intended for rotary drilling in which the rotation unit 7 is used for rotating the drilling equipment 9 around its longitudinal axis in direction R and, at the same time, the rotation unit 7 and the drilling equipment 9 connected to it are fed with feed force F by means of the feed device 6 in drilling direction B. Thus, the drill b...

Abstract

A fuel tank for a fuel-operated down-the-hole drill including a drill bit, is provided. A largest rotation diameter of the fuel tank is provided at or in connection with drilling equipment and is sufficiently small in order to be able to insert the fuel tank into a drill hole.

Description

BACKGROUND[0001]The invention relates to a fuel tank for a fuel-operated down-the-hole drill comprising a drill bit.[0002]Furthermore, the invention relates to a method for feeding a fuel-operated down-the-hole drill comprising a drill bit with fuel.[0003]The invention also relates to an arrangement for feeding a fuel-operated down-the-hole drill comprising a drill bit with fuel, the arrangement comprising a down-the-hole drill and a fuel tank as well as means for feeding fuel from the fuel tank to the down-the-hole drill.[0004]The invention also relates to a rock drilling rig.[0005]Holes can be drilled in rock by means of various rock drilling machines. Drilling may be performed with a method combining percussions and rotation (percussive drilling), or drilling may be based on mere rotation without a percussive function (rotary drilling). Further, percussive drilling may be classified according to whether the percussion, device is outside the drill hole or in the drill hole during ...
