Abstract
Method and device for aligning a drill aggregate (1) in a tunnel (2) relative to a predetermined plane transverse to the tunnel. The wall of the tunnel is surface lighted by lamps (9) in the areas of marks (5), e.g. in form of lines painted on the tunnel wall. An optical system (6) on the drill aggregate senses the marks and generates electric signals which are fed to a presentation unit (7). Then a carrier (3) and/or a drill unit (4) forming part of the drill aggregate (1) are moved until the presentation unit (7) shows that the drill unit is in the desired position.
Description
95002.utl 2169614 Method and device for alignin~ a drill ag~re~ate The present invention relates to a method and a device for ~ligning a drill aggregate in a tunnel relative to a predetermined plane being transverse to the tunnel.
According to a prior art solution, see US-A-4 586 571, two lamps are arranged on the drill aggregate. These are directed in opposite directions and emit narrow light beams.
The drill aggregate is then moved so that the light beams light marks made on the tunnel wall. When the drill aggregate stands in the desired position the drill unit is aligned in the desired direction, after which drilling is started. This method works well when the operator is close to the drill aggregate and can see when the marks on the tunnel wall are lighted.
The present invention, which is defined in the accompanying claims, aims at achieving a method and a device for ~ligning a drill aggregate in a tunnel relative to a predetermined plane transverse to the tunnel. More specifically it is intended to achieve a method and a device which are suitable for ~ligning a drill aggregate either the operator is close to the aggregate or at a distance from the aggregate and/or the drill aggregate is positioned automatically.
An embodiment of the invention is described below with reference to the appendeddrawings in which fig l shows a lateral view of a drill aggregate in which the invention forms a part. Fig 2 shows a view from above of the drill aggregate according to fig l.
The drill aggregate shown in the drawings is a production drill aggregate, i.e. a drill aggregate which is mainly intended for drilling upwards. Other types of drill aggregates can also be used according to the invention. The drill aggregate 1 comprises a carrier 3 on which a drill unit 4 is swingably arranged about axes 11, 12 and 13. The drill unit is furthermore movable perpendicularly to the longitudinal axis of the carrier 3 along guides 15. The drill unit 4 is movable along a feed beam 14.
The carrier 3 is provided with four wheels 8 by means of which the carrier 3 can be moved in a tunnel 2. On the tunnel wall there are two marks 5 in form of painted 95002.utl 2169614 .
lines by means of which the drill unit can be aligned in a predetermined plane transverse to the tunnel 2. The predetermined plane is parallel to a plane through the marks 5. On one of the guides 15 an optical system in form of two video cameras 6 is arranged. The optical axes of the video cameras are parallel to the guides 15. Two lamps 9 are arranged on the carrier 3 for surface lighting an area of the tunnel wall about the marks 5 unless the tunnel is lighted in some other way. The optical system generates electric signals which are fed to a presentation unit 7, in the shown example a viewing screen, which shows the position of the drill unit 4 relative to the marks 5.
The carrier 3 is moved by means of the wheels 8 until the pictures from the video cameras 6 obtain the desired positions on the presentation unit 7. If the drill unit 4 and the feed beam 14 are movable relative to the carrier 3 in the longitudinal direction of the carrier such a movement can be used for obtaining the correct position of the drill unit, i.e. in the above mentioned predetermined plane. If movement occurs both with carrier and drill unit the signals to the presentation unit are suitably corrected so that a correct position of the drill unit is marked in the same place on the presentation unit independent of the displacement of the drill unit relative to the carrier.
In the above mentioned example two video cameras are used. It is also possible to use mirrors, e.g. prisms, so that both marks 5 can be reproduced by one video camera, which has its optical axis parallel to the longitudinal axis of the carrier. The lamps 9 are shown on the drill aggregate but can be placed anywhere if only they create a surface lighting at the marks 5 so that these can be reproduced by the optical system.
-The presentation unit is shown as a viewing screen arranged on the drill aggregate.When remotely controlling the drilling the p~ese~ lion unit is advantageously placed in an operator's room at a distance from the drill aggregate. This distance can be of any size if suitable signal tr~nsmi~.~ion is arranged. Instead of a viewing screen the presentation unit can be a computer if more or less advanced automation is desired.
Viewing screen and computer can of course be used simultaneously.
