Abstract

The optical sighting device for the parallel and perpendicular movement of an excavator shovel (1) comprises a laser gun (5) and two transparent sighting discs (2,3). These are mounted directly on the excavator shovel (1) and lie in the line of sight of the excavator operator. Markings are provided on both sides of the discs (2,3) and aligned with the laser beam (4) to allow the operator to move the excavator shovel (1) parallel to the laser beam (4) which appears as a light spot on each disc (2,3). The sighting device is used for excavating long drainage channels. The operator may have a remote-control transmitter cooperating with a receiver mounted on the laser gun (5) coupled to a servomotor for pivoting the laser gun (5) about a vertical axis (A-A).

Description

Beschreibung description

Titel: Optische Visiereinrichtung zur geraden und parallelen Steuerung einer Baggerschaufel wendungsgebiet: Die Erfindung betrifft eine optische Visiereinrichtung zur geraden und parallelen Steuerung einer Baggerschaufel, die dem Baggerführer eine exakte Steuerung der Baggerschaufel ermöglicht, wie sie insbesondere beim Ziehen von langen Drainagegräben mit geringem Gefälle erforderlich ist.Title: Optical sighting device for straight and parallel control Field of application of an excavator shovel: The invention relates to an optical sighting device for straight and parallel control of an excavator shovel, which the excavator operator allows precise control of the excavator shovel, especially when pulling of long drainage trenches with a slight gradient is required.

Zweck: Die Nutzbarmachung von sumpfigem Gelände kann dadurch erfolgen, daß Graben ausgehoben werden, in welche Drainagerohre verlegt werden. Anschließend werden die Gräben wieder zugeschüttet.Purpose: The utilization of marshy terrain can be done by that trenches are dug into which drainage pipes are laid. Afterward the trenches are filled in again.

Diese Gräben naben oft eine große Länge und nur wenig Gefälle. Um einen guten und dauerhaften Abfluß des Wassers in den Drainagerohren zu gewährleisten, ist es erforderlich, daß der Aushub des Grabens möglichst exakt und mit konstantem Gefälle erfolgt. These trenches often have a great length and only a slight slope. Around to ensure a good and permanent drainage of the water in the drainage pipes, It is necessary that the excavation of the trench is as precise as possible and with a constant Gradient takes place.

Stand der Technik: Die Aufgabe, den Drainagegraben mittels Bagger mit möglichst konstantem Gefälle auszuheben, wurde bisher dadurch gelöst, daß in gewissen Intervallen die Uöhe der Grabensohle mittels einer Meßeinrichtung (z.B. Wasserwaage, iveliereinrichtung) gemessen wurde und dem Baggerführer entsprechende Information über das Meßergebnis gegeben wurde.State of the art: The task of digging the drainage trench digging with as constant a gradient as possible has so far been achieved in that in At certain intervals the height of the trench bottom by means of a measuring device (e.g. Spirit level, leveling device) was measured and the excavator operator accordingly Information about the measurement result was given.

Kritik am Stand der Technik: Diese Methode erfordert eine zusätzliche Arbeitskraft und ist verhältnismäßig ungenau.Criticism of the state of the art: This method requires an additional one Labor force and is relatively imprecise.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, zusätzliche Meßarbeiten zu ersetzen und einen genauen Aushub des Drainagegrabens zu ermöglichen.Task: The invention is based on the task of additional measurement work to replace and to enable a precise excavation of the drainage trench.

Lösung: Die Aufgabe wird erfindungsmäßig dadurch gelöst, daß an der Maggerschaufel (1) zwei lichtdurchlässige Scheiben (2) und (3) befestigt sind, die von einem gebündeltem Lichtstrahl (4) durchstrahlt werden. Der Lichtstrahl wird von einer handelsüblichen Laserkanone ausgesendet, die z.B. am Anfang des zu öffnenden Drainagegrabens aufgestellt wird. Bei weichem bonden ist es vorteilhaft, ein Gerät zu verwenden, das den Winkel oc zwischen dem Lichtstrahl und der Horizontalen automatisch konstant hält. Die beiden Scheiben (2) und (3) befinden sich im blickfeld des Baggerführers. Illit Hilfe von Markierungen, die auf den beiden Scheiben angebracht sind, kann der Baggerführer den Arbeitshub der Schaufel (1) entlang des Lichtstrahls (4), der auf den Scheiben als Lichtpunkt sichtbar ist, steuern.Solution: The object is achieved according to the invention in that the Magger scoop (1) two translucent discs (2) and (3) are attached to the be penetrated by a bundled light beam (4). The ray of light will emitted by a commercially available laser cannon, e.g. at the beginning of the Drainage trenches is set up. With soft bonding it is advantageous to use a device to use that automatically adjust the angle oc between the light beam and the horizontal keeps constant. The two discs (2) and (3) are in the field of vision of the excavator operator. Illit the help of markings that are made on the two discs can the excavator operator the working stroke of the shovel (1) along the light beam (4), the is visible on the panes as a point of light.

Sowohl dinkel- als auch höhenabweichungen der Schaufel sind so fiir den Dag=erfilhrer leicht erkennbar und können sofort l orrigiert werden. Both spelled and height deviations of the shovel are so the day instructor is easily recognizable and can be corrected immediately.

Bei lanzen Drainaregraben kann es vorkommen, daß infolfire einer seitlichen Abweichung - die für die Funktion des T)rainagegrabens ohne Bedeutung ist - der Lichtstrahl seitlich über die Scheiben (2) und (3) hinaus wandert und dann für den Baggerführer nicht mehr sichtbar ist. With lance drainage trenches it can happen that infolfire one lateral deviation - which is irrelevant for the function of the trench is - the light beam travels laterally over the panes (2) and (3) and is then no longer visible to the excavator operator.

Um den Lichtstrahl wieder in den Bereich der Scheiben (2) und (3) zu lenken, kann die Laserkanone (5) um eine vertikale Achse A-A geschwenkt werden. Dieser chwenkvorgang wird vom Baggerführer huber eine Funk- Pernsteuerung gesteuert. Dabei bedient der Baggerführer den Sender der Fernsteuerung; der Empfänger befindet sich an der Laserkanone. Das Empfängersignal schaltet einen Servomotor, der die Schwenkbewegung der Laserkanone (5) um die vertikale Achse A-A bewirkt. To bring the light beam back into the area of the panes (2) and (3) To steer, the laser gun (5) can be pivoted about a vertical axis A-A. This pivoting process is controlled by the excavator operator using a remote radio control. The excavator operator operates the remote control transmitter; the recipient is located at the laser cannon. The receiver signal switches a servo motor that controls the Pivoting movement of the laser cannon (5) about the vertical axis A-A causes.
