Abstract

The sensor plane containing two or more sensors is parallel to the reference plane, and two or more of these sensor planes are parallel to and at a variable distance from each other. The whole system can be moved parallel to the reference plane. The distances between sensor planes are varied in the same direction by a screw whose pitch continuously varies; or it is varied by compression, with individual planes separated from each other by an elastic material.

Einrichtung zur Orientierung an .einer dux cn einen rotierenden LASER-Strahl erzeugten Ebene.Device for orientation on a dux cn a rotating LASER beam generated plane. Zweck der weiteren Ausgestaltung der Erfindung, gem. P 25 18 427.2, G 73 13 990.6, ist es, eine Orientierung an einer Bezugsebene, die von einem LASER-Strahl erzeugt wird, unabhängig von der Aufstellungsrichtung des LASERS zu ermöglichen.Purpose of the further development of the invention, according to P 25 18 427.2, G 73 13 990.6, is to have an orientation on a reference plane that of a LASER beam, regardless of the direction in which the LASERS to enable. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß in einem weiteren Ausführungsbeispiel drei Photoempfänger, dreieckförmig angeordnet, eine Sensorebene bilden, die parallel zu der vom LASER-Strahl erzeugten Bezugsebene liegt und mehrere dieser Sensorebenen, denen jeweils optische Anzeigen oder Einrichtungen zur automatischen Steuerung zugeordnet sind, parallel zueinander angeordnet werden. Der gegenseitige Abstand der Sensorebenen ist zwecks Anpassung an den entfernungsabhängigen LASER-Strahldurchmesser gleichsinnig veränderbar und die Gesamtanordnung senkrecht zur Bezugsebene verschiebbar.According to the invention the object is achieved in that in a further embodiment three photoreceivers, arranged in a triangle, one sensor level that are parallel to the reference plane generated by the LASER beam and several of these sensor levels, to which optical displays or devices for automatic control are assigned, parallel to one another to be ordered. The mutual spacing of the sensor levels is in the same direction for the purpose of adapting to the distance-dependent LASER beam diameter changeable and the overall arrangement displaceable perpendicular to the reference plane. Der Vorteil einer solchen Einrichtung liegt, zusätzlich zu den Darlegungen gem. P 23 18 427·2, G 73 13 89o.6, in einer Verwendbarkeit über einen Winkel-· bereich von 360 Grad, so daß beispielsweise der Bediener einer Baumaschine, an der eine solche Einrichtung installiert ist, nicht mehr gezwungen ist, die Maschine zu wenden, um auf die Aufstellungsrichtung des LASERS hin zu arbeiten.The advantage of such a facility is, in addition to the explanations according to P 23 18 427 2, G 73 13 89o.6, usable over an angle range of 360 degrees, so that, for example, the operator of a construction machine, at which such a device is installed, is no longer forced to turn the machine to face the direction of installation of the LASER work. PatentansDruch:Patent claim: 1 ., Einrichtung zur Orientierung an einer durch einen rotierenden LASER-Strahl erzeugten Bezugsebene, dadurch gekennzeichnet, daß zwei oder mehr Photoempfänger in einer Sensorebene parallel zur Bezugsebene angeordnet sind, und zwei oder mehr dieser Sensorebenen parallel zueinander mit veränderbarem Abstand liegen, wobei die Gesamtanordnung parallel zur Bezugsebene verschiebbar ist.1., Device for orientation on a rotating by a LASER beam generated reference plane, characterized in that two or more photoreceivers in a sensor plane parallel to Reference plane are arranged, and two or more of these sensor planes are parallel to each other with a variable distance, wherein the overall arrangement is displaceable parallel to the reference plane. 2.
