A rack is secured to the guide column and a feed mechanism for moving the drilling device includes a pinion in meshed engagement with the rack. Guide members on the support members fit into correspondingly shaped guide grooves on the drilling device.

Description

Die Erfindung betrifft eine Stativbohrvorrichtung mit einer Fussplatte, einer mit der Fussplatte verbundenen Führungssäule und einem längs der Führungssäule verschiebbaren Bohrgerät, wobei die Führungssäule und das Bohrgerät miteinander korrespondierende Führungsmittel aufweisen und eine Vorschubeinrichtung für das Bohrgerät vorgesehen ist.The invention relates to a tripod drilling device with a base plate, a guide column connected to the base plate and a drill which can be displaced along the guide column, the guide column and the drill having guide means which correspond to one another and a feed device is provided for the drill.

Neben den bisher aus der Metallbearbeitung bekannten, stationären Bohrvorrichtungen werden Bohrvorrichtungen der obengenannten Art seit einiger Zeit auch als mobile Geräte im Bauwesen verwendet. Solche Bohrvorrichtungen werden hauptsächlich zusammen mit diamantbestückten Bohrkronen eingesetzt. Mit diesen Bohrkronen können auch in mit Eisenarmierungen versehenen Bauwerken Durchbrüche von grösserem Durchmesser hergestellt werden.In addition to the stationary drilling devices previously known from metalworking, drilling devices of the type mentioned above have also been used as mobile devices in the construction industry for some time. Such drilling devices are mainly used together with diamond-tipped drill bits. These drill bits can also be used to produce breakthroughs with a larger diameter in iron-reinforced structures.

Ein wesentliches Problem bei diesen Stativbohrvorrichtungen besteht in der Führung des Bohrgerätes. Durch die für den grössten Bohrlochmesser erforderliche Ausladung des Bohrgerätes sowie die insbesondere bei den grösseren Werkzeugen aufzubringenden Kräfte können an den Führungen hohe Kippmomente und an der Führungssäule grosse Biege- und Torsionsbelastungen auftreten. Wie erwähnt, müssen diese Geräte mobil sein und möglichst von einer oder höchstens zwei Personen gehandhabt werden können. Die Führungssäule kann somit aufgrund des sich erhöhenden Gesamtgewichtes der Bohrvorrichtung nicht beliebig verstärkt werden.A major problem with these tripod drilling devices is the guidance of the drilling device. Due to the outreach of the drilling device required for the largest borehole knife and the forces to be exerted, in particular with the larger tools, high tilting moments and Large bending and torsional loads occur on the guide column. As mentioned, these devices must be mobile and, if possible, be handled by one or at most two people. The guide column can therefore not be reinforced arbitrarily due to the increasing total weight of the drilling device.

Bei bekannten Bohrvorrichtungen weist die Führungssäule einen U- oder C-förmigem Querschnitt auf. Das Bohrgerät ist dabei an Führungen im Innern der Führungssäule gelagert. Das Bearbeiten der Führungen durch deren Anordnung im Innern einer solchen Führungssäule ist sehr aufwendig und kann meist nur mit Spezialwerkzeugen vorgenommen werden. Da aufgrund der Querschnittsgestaltung nur der mit der Lagerung für die Bohrspindel versehene Teil des Bohrgerätes über die Führungssäule hinausragen kann, muss die Vorschubeinrichtung für das Bohrgerät ebenfalls im Innern der Führungssäule angeordnet werden. Somit ist eine aufwendige Konstruktion mit Getriebe, Gewindespindel und Gewindemutter erforderlich.In known drilling devices, the guide column has a U-shaped or C-shaped cross section. The drill is mounted on guides inside the guide column. The processing of the guides by their arrangement inside such a guide column is very complex and can usually only be done with special tools. Since, due to the cross-sectional design, only the part of the drilling device provided with the bearing for the drilling spindle can protrude beyond the guide column, the feed device for the drilling device must also be arranged inside the guide column. This means that a complex construction with gear, threaded spindle and threaded nut is required.

Der Erfindung liegt die Aufgabe zugrunde, eine wirtschaftlich herstellbare Stativbohrvorrichtung zu schaffen, wobei sich insbesondere Führungssäule und Vorschubeinrichtung durch einfachen Aufbau auszeichnen.The invention has for its object to provide an economically producible tripod drilling device, in particular guide column and feed device are characterized by a simple structure.

Gemäss der Erfindung wird dies dadurch erreicht, dass die Führungssäule aus zwei in seitlichem Abstand voneinander angeordneten, parallel zueinander verlaufenden Trägern besteht, wobei die Träger die Führungsmittel für das dazwischen angeordnete Bohrgerät und Angriffsmittel für die Vorschubeinrichtung aufweisen.According to the invention, this is achieved in that the guide column consists of two supports arranged at a lateral distance from one another and running parallel to one another, the supports having the guide means for the drilling device arranged therebetween and engagement means for the feed device.

Die Führungssäule besteht somit aus zwei Teilen, welche einzeln hergestellt und bearbeitet werden können. Da die Führungen an den Trägern frei zugänglich sind, können wesentlich grössere, rationeller arbeitende Werkzeuge für deren Bearbeitung eingesetzt werden. Ein wesentlicher Vorteil des Aufteilens der Führungssäule in zwei Träger besteht auch darin, dass die Führungssäule keine Wanne für die bei der Gesteinsbearbeitung mittels Diamantwerkzeugen erforderliche, grosse Menge an Kühlwasser bildet. Beispielsweise beim Bohren an einer Wand kann das Kühlwasser ungehindert zwischen den beiden, bei einem solchen Anwendungsfall horizontal verlaufenden Trägern abfliessen. Durch die Ausbildung der Führungssäule als zwei voneinander getrennte Träger kann das Bohrgerät die Führungssäule nicht nur auf der Seite der Spindellagerung, sondern auch auf der gegenüberliegenden Seite überragen. Dies ermöglicht die Anordnung der Vorschubeinrichtung auf der Aussenseite der Führungssäule.The guide column thus consists of two parts, which can be manufactured and processed individually. Since the guides on the supports are freely accessible, much larger, more rationally working tools can be used for their processing. A major advantage of dividing the guide column into two supports is also that the guide column does not form a trough for the large amount of cooling water required for stone processing using diamond tools. For example, when drilling on a wall, the cooling water can flow freely between the two supports that run horizontally in such an application. By designing the guide column as two separate supports, the drilling device can project beyond the guide column not only on the side of the spindle bearing, but also on the opposite side. This enables the feed device to be arranged on the outside of the guide column.

Aus Gewichts- und Kostengründen werden für die Führungssäule vorzugsweise aus Leichtmetallegierungen bestehende Strangguss- bzw Strangpressprofile verwendet. Bei beiden Verfahren sind die Formkosten relativ hoch. Für eine wirtschaftliche Herstellung ist es daher zweckmässig, dass beide Träger den gleichen Querschnitt aufweisen. Die festen Formkosten können somit auf die doppelte Menge von Profilen verteilt werden, so dass diese wesentlich günstiger hergestellt werden können. Unter Umständen können dabei auch Standardprofile von den Halbzeug-Herstellern verwendet werden. Solche Profile sind besonders günstig, da sie in grossen Mengen hergestellt werden.For weight and cost reasons, extruded or extruded profiles made of light metal alloys are preferably used for the guide column. The molding costs are relatively high in both processes. For economical production, it is therefore expedient for both carriers to have the same cross section. The fixed molding costs can thus be distributed over twice the amount of profiles, so that they can be manufactured much cheaper. Under certain circumstances, standard profiles from the semi-finished product manufacturers can also be used. Such profiles are particularly cheap because they are manufactured in large quantities.

In der Führungssäule tritt hauptsächlich eine Biegebelastung. auf. Diese Biegebelastung wirkt in einer in Längsrichtung durch die Träger verlaufenden Ebene. Daneben entsteht jedoch auch eine Torsionsbelastung auf die Führungssäule. Um diese kombinierte Belastung aufzunehmen, ist es vorteilhaft, die Träger im Querschnitt im wesentlichen L-förmig auszubilden. Die kürzeren Schenkel des L-förmigen Profils können dabei relativ kurz ausgebildet werden. Bei Bedarf können am L-förmigen Profil auch zusätzliche Versteifungsrippen angebracht werden.There is mainly a bending load in the guide column. on. This bending load acts in a plane running in the longitudinal direction through the beams. In addition, however, there is also a torsional load on the guide column. In order to absorb this combined load, it is advantageous to design the beams in an essentially L-shaped cross section. The shorter legs of the L-shaped profile can be made relatively short. If necessary, additional stiffening ribs can also be attached to the L-shaped profile.

Da mit demselben Gerät sowohl dünne als auch dicke Wände, Decken und Böden durchbohrt werden müssen, ist die dazu erforderliche Führungssäule relativ lang. Durch die Ausbildung der Führungssäule als zwei einzelne Träger besteht die Möglichkeit, dass sich die freien Enden der Träger zueinander oder voneinander weg biegen. Um dies zu vermeiden, ist es zweckmässig, an dem der Fussplatte entgegengesetzten Ende der Träger eine die Träger miteinander verbindende Deckplatte anzuordnen. Die Deckplatte kann mit den freien Enden der Träger verschraubt, vernietet oder verschweisst werden. Neben dem Verbinden der Träger erfüllt eine solche Deckplatte jedoch noch eine andere Funktion. So kann durch die Deckplatte die rückwärtige Endstellung des Bohrgerätes begrenzt und ein versehentliches Ausfahren aus der Führungssäule verhindert werden.Since both thin and thick walls, ceilings and floors have to be drilled with the same device, the guide column required for this is relatively long. Through training the guide column as two individual supports, there is the possibility that the free ends of the supports will bend towards or away from each other. In order to avoid this, it is expedient to arrange a cover plate connecting the carriers to one another at the end of the carrier opposite the base plate. The cover plate can be screwed, riveted or welded to the free ends of the carrier. In addition to connecting the supports, such a cover plate also fulfills another function. In this way, the rear end position of the drilling device can be limited by the cover plate and inadvertent movement out of the guide column can be prevented.

Die Führungen an der Führungssäule müssen in verschiedenen Richtungen wirkende Kräfte aufnehmen. Um dies zu ermöglichen, ist es vorteilhaft, die Führungsmittel als mit entsprechenden Gegenprofilen am Bohrgerät in Eingriff stehende, schwalbenschwanzförmige Leisten auszubilden. Schwalbenschwanzförmige Führungen ermöglichen auch ein Einstellen des Betriebsspieles auf relativ einfache Weise. Da die Führungen durch die zweiteilige Ausbildung der Führungssäule gut zugänglich sind, ist allenfalls auch eine spanabhebende Bearbeitung der Führungsleisten möglich.The guides on the guide pillar must absorb forces acting in different directions. In order to make this possible, it is advantageous to design the guide means as dovetail-shaped strips which engage with corresponding counter profiles on the drilling device. Dovetail-shaped guides also allow the operating clearance to be set in a relatively simple manner. Since the guides are easily accessible due to the two-part design of the guide column, machining of the guide strips is possible at most.

Bei Geräten zur Gesteinsbearbeitung tritt an den Führungen ein relativ hoher Verschleiss auf. Durch den Verschleiss wird das Spiel in den Führungen erhöht. Wird dieses Spiel zu gross, ist ein störungsfreies Arbeiten nicht mehr möglich, so dass das Spiel beseitigt werden muss. Dies kann beispielsweise durch einstellbare Führungen erfolgen. Das Einstellen des richtigen Spiels ist jedoch sehr zeitaufwendig und kann durch die Bedienungsperson meist nicht selbst ausgeführt werden. Eine zweckmässige Lösung besteht darin, dass die Gegenprofile lösbar mit dem Bohrgerät verbunden sind. Bei zu gross gewordener Abnützung können somit die Gegenprofile auf einfache Weise gegen neue, passende ausgetauscht werden. Die zeitaufwendige Einstellarbeit entfällt dabei. Durch die auswechselbare Ausbildung der Gegenprofile können auch Kunststoffe mit guten Gleiteigenschaften, wie zB Polyamid ("Nylon"), Polytetrafluoräthylen ("Teflon") oder dgl. verwendet werden. Solche Kunststoffe weisen ausserdem eine gewisse Elastizität auf und können sich somit den Führungen an den Trägern anpassen.In devices for stone processing, the guides are subject to relatively high wear. The play in the guides is increased due to wear. If this game becomes too large, trouble-free working is no longer possible, so the game must be eliminated. This can be done for example by adjustable guides. However, setting the correct game is very time-consuming and usually cannot be carried out by the operator himself. An expedient solution is that the counter profiles are detachably connected to the drilling device. If the wear has become too large, the counter profiles can easily be exchanged for new, suitable ones. The time-consuming adjustment work is not necessary. The interchangeable design of the counter profiles means that plastics with good sliding properties can also be used Shafts such as polyamide ("nylon"), polytetrafluoroethylene ("Teflon") or the like. Such plastics also have a certain elasticity and can therefore adapt to the guides on the carriers.

Durch das beidseitig offene Profil der Führungssäule kann das Bohrgerät die Führungssäule auch auf der der Bohrspindel gegenüberliegenden Seite überragen. Somit ist es möglich, den Vorschubantrieb ausserhalb der Führungssäule anzuordnen. Eine vorteilhafte Ausbildung besteht darin, dass die Angriffsmittel an den Trägern als Zahnstange für die am Bohrgerät angeordnete Vorschubeinrichtung ausgebildet sind. Eine mittels einer Zahnstange arbeitende Vorschubeinrichtung ermöglicht die Verwendung genormter Bauteile. Falls der Hub eines erfindungsgemässen Stativbohrgerätes nachträglich geändert werden soll, beispielsweise durch Verlängerung oder Austausch der Führungssäule, kann die Zahnstange wieder verwendet und ebenfalls um ein entsprechendes Stück verlängert werden. Zahnstangen können auch als genormte Meterware bezogen und der Länge der Führungssäule entsprechend angepasst werden.Due to the profile of the guide column, which is open on both sides, the drilling device can also project beyond the guide column on the side opposite the drilling spindle. It is therefore possible to arrange the feed drive outside the guide column. An advantageous embodiment consists in that the engagement means on the carriers are designed as a toothed rack for the feed device arranged on the drilling device. A feed device working by means of a rack enables the use of standardized components. If the stroke of a tripod drilling device according to the invention is to be changed subsequently, for example by lengthening or replacing the guide column, the toothed rack can be used again and can also be lengthened by a corresponding amount. Racks can also be purchased as standard yard goods and adjusted to the length of the guide column.

Die Verbindung des Bohrgerätes mit der Zahnstange kann beispielsweise über eine Schneckenwelle erfolgen. Eine solche Vorschubeinrichtung ist in der Regel selbsthemmend. Dies bedeutet, dass das Bohrgerät unabhängig von der Lage der Führungssäule selbsttätig in der jeweiligen Stellung verbleibt. Ein Nachteil einer solchen Vorschubeinrichtung besteht jedoch darin, dass das Uebersetzungsverhältnis sehr gross ist und somit insbesondere der Rückhub und der Vorschub in die zuletzt eingenommene Stellung, beispielsweise zum Entfernen des Bohrkerns, sehr zeitaufwendig ist. Für eine einfachere Handhabung ist es daher zweckmässig, dass die Vorschubeinrichtung eine mit einem Ritzel verbundene Antriebswelle aufweist. Dieses Ritzel kann mit der Zahnstange dauernd in Eingriff stehen und beispielsweise über ein Handrad manuell oder über einen Motor angetrieben werden. Im Falle einer manuellen Betätigung des Vorschubes kann die Antriebswelle auch an beiden Enden mit Mitnahmemitteln versehen sein, so dass das Handrad je nach Lage der Bohrvorrichtung auf der linken oder auf der rechten Seite des Bohrgerätes angesetzt werden kann.The drill can be connected to the rack, for example, via a worm shaft. Such a feed device is usually self-locking. This means that the drill automatically remains in the respective position regardless of the position of the guide column. A disadvantage of such a feed device, however, is that the transmission ratio is very large and, in particular, the return stroke and the feed into the last position, for example for removing the drill core, are very time-consuming. For easier handling, it is therefore expedient for the feed device to have a drive shaft connected to a pinion. This pinion can be in constant engagement with the rack and can be driven manually or by a motor, for example using a handwheel. In the case of manual actuation of the feed, the drive shaft can also be provided with driving means at both ends, so that the handwheel depends on the position the drilling device can be placed on the left or on the right side of the drilling rig.

Die Arme 4b, 4c sind mit ebenfalls auswechselbaren Backen 8 versehen, welche sich an der Stirnkante der Träger 2a, 2b abstützen. Der Träger 2b ist mit einer Zahnstange 9 verbunden.The stand drilling device according to the invention shown in FIGS. 1 and 2 has a base plate 1 and a guide column, designated overall by 2, connected to the base plate 1. The guide column 2 consists of two supports 2a, 2b arranged at a lateral distance from one another and running parallel to one another.

Die Antriebswelle 10 ist mit einem Ritzel 10a versehen, welches mit der Zahnstange 9 in Eingriff steht. Für die Betätigung der Antriebswelle 10 weist diese an beiden Enden einen Mehrkant 10b auf. An einem Ende der mittels eines Stellringes 11 gegen axiales Verschieben gesicherten Antriebswelle 10 ist ein Handrad 12 auf den Mehrkant 10b aufgesteckt. Je nach Lage der Stativbohrvorrichtung kann das Handrad 12 jedoch auch abgenommen und auf der entgegengesetzten Seite auf den Mehrkant 10b aufgesteckt werden.This rack 9 is used to feed the drill 4. For this purpose, a total of 10 is indicated drive shaft on the drill 4 rotatably mounted. The drive shaft 10 is provided with a pinion 10 a, which is in engagement with the rack 9. For the actuation of the drive shaft 10, this has a polygon 10b at both ends. At one end of the drive shaft 10, which is secured against axial displacement by means of an adjusting ring 11, a handwheel 12 is attached to the polygon 10b. Depending on the position of the tripod drilling device, however, the handwheel 12 can also be removed and placed on the polygon 10b on the opposite side.

Zur Begrenzung der Bohrtiefe ist ein Anschlag 13 vorgesehen. Dieser Anschlag 13 ist mit Hilfe eines in einer schwalbenschwanzförmigen Nute 2e, 2f geführten Gleitsteines 14 sowie eines Klemmhebels 15 in beliebiger Lage feststellbar. Der Anschlag 13 kann erforderlichenfalls auch auf dem anderen Träger 2a angeordnet werden. Da die beiden Träger 2a, 2b denselben Querschnitt aufweisen, können diese ohne weiteres aus gleichen Profilen hergestellt werden. Dies ermöglicht die Herstellung des Profils in grösseren Mengen und dadurch eine wirtschaftlichere Herstellung.A stop 13 is provided to limit the drilling depth. This stop 13 can be locked in any position with the aid of a sliding block 14 guided in a dovetail-shaped groove 2e, 2f and a clamping lever 15. If necessary, the stop 13 can also be arranged on the other support 2a. Since the two beams 2a, 2b have the same cross-section, they can easily be produced from the same profiles. This enables the profile to be produced in larger quantities and therefore more economically.
