Abstract

Arrangement for positioning a bore crown 1 in a positioning plane 2. A bore rig 3 is provided with two video cameras 9 for detecting the position of a light source 8 next to the bore crown. The video cameras are oriented in parallel. The viewing fields of the video cameras are offset in relation to each other in such a way that the light source gives two points 20, 21 on a monitor 10 common to the two cameras if the light source is situated outside the positioning plane, and one point 11 if the light source is situated in the positioning plane. <IMAGE>

Description

465 044 2 ljuskälla företrädesvis för infrarött ljus. Två videokameror 9 är anordnade på avstånd från varandra på bararen 3 och parallellt inriktade i förhållande till varandra samt riktade mot en tunnelfront 16 framför vilken ett positioneringsplan 2 befinner sig. De två videokamerorna är anslutna till en gemensam monitor l0 på vilken en borrplan 17 är placerad. Lämpligen används en transparent plastfolie på vilken tunnelns kontur 18 och de olika borrhâlens lägen 19 är angivna. De tvà videokamerorna förses lämpligem med filter som enbart släpper igenom infrarött ljus. Detta medför att operatören slipper en mängd onödig information på skärmen och således får lättare att rikta in borrkronan. Vid återgivningen av bíldfålten från de två videokamerorna förskjuts bildfälten relativt varandra på elektronisk våg så att en given punkt i positioneringsplanet 2 avbildas på monitorns 10 skärm som en enda punkt av de två videokamerorna. Detta medför att markeringen 8 ger upphov till tvâ punkter 20,21 på monitoren om markeringen 8 ej befinner sig i positioneringsplanet 2 och en punkt när markeringen befinner sig i positioneringsplanet. För att positionera borrkronan 1 rätt i förhållande till borrplanen 17 manövreras hydraulcylindrarna 12,13 och 15 så att de tvâ punkterna 20,21 fås att sammanfalla i en punkt ll som skall sammanfalla med ett borrhálsläge 19. När så har skett befinner sig markeringen 8 med stor noggrannhet i rätt läge i positioneringsplanet 2. Borrplanen 17 är något korrigerad i förhållande till det önskade borrhålsmönstret för att ta hänsyn till att markeringens 8 läge ej överensstämmer med borrkronans läge. För att få borrsträngen 7 i rätt riktning för borrningen utnyttjas lämpligen vinkelgivare i lederna mellan bäraren 3 och matarbalken 5. 465 044 2 light source preferably for infrared light. Two video cameras 9 are arranged at a distance from each other on the bar 3 and are parallel oriented in relation to each other and directed towards a tunnel front 16 in front of which a positioning plane 2 is located. The two camcorders are connected to a common monitor 10 on which a drilling plane 17 is located. Suitably a transparent plastic foil is used on which the contour 18 of the tunnel and the positions 19 of the various boreholes are indicated. The two camcorders are conveniently equipped with filters that only transmit infrared light. This means that the operator avoids a lot of unnecessary information on the screen and thus makes it easier to align the drill bit. When reproducing the image field from the two camcorders, the image fields are shifted relative to each other on an electronic scale so that a given point in the positioning plane 2 is imaged on the screen of the monitor 10 as a single point by the two camcorders. This means that the marking 8 gives rise to two points 20, 21 on the monitor if the marking 8 is not in the positioning plane 2 and one point when the marking is in the positioning plane. To position the drill bit 1 correctly in relation to the drilling plane 17, the hydraulic cylinders 12, 13 and 15 are operated so that the two points 20, 21 are made to coincide in a point 11 which is to coincide with a borehole position 19. When this has been done, the marking 8 is located with great accuracy in the correct position in the positioning plane 2. The drilling plane 17 is slightly corrected in relation to the desired borehole pattern to take into account that the position of the marking 8 does not correspond to the position of the drill bit. In order to get the drill string 7 in the right direction for the drilling, angle sensors in the joints between the carrier 3 and the feed beam 5 are suitably used.
