Abstract
Description
Die Erfindung betrifft einen Ständer für ein Bohrgerät gemäss dem Oberbegriff des
Patentanspruchs 1.The invention relates to a stand for a drill according to the preamble of
Zur Herstellung von Bohrungen in harten Untergründen, wie beispielsweise Beton, Gestein oder dergleichen werden Bohrgeräte verwendet, die bei bestimmten Anforderungen, inbesondere an die Qualität des herzustellenden Bohrloches, mit Hilfe eines Ständers beim Bohrvorgang geführt werden müssen. Ein derartiger Ständer ist beispielsweise aus dem DE-U-297 13 139 bekannt. Dieser Ständer setzt sich zusammen aus einer eine Auflagefläche aufweisenden Grundplatte, zwei Lagerböcken, einer Rasterplatte, einer Führungssäule und einem axial versetzbaren Verriegelungselement. Die beiden Lagerböcke und die Rasterplatte sind an der Grundplatte angeordnet und ragen von dieser ab. Eine Schwenkachse, um die die Führungssäule gegenüber der Grundplatte schwenkbar ist, erstreckt sich durch beide Lagerböcke und die Führungssäule. Die Rasterplatte weist mehrere, beispielsweise unter gleichen Winkeln voneinander beabstandete, Bohrungen auf, die auf einer um die Schwenkachse verlaufenden Kreisbahn angeordnet sind. Mit Hilfe des Verriegelungselementes in Form einer Spannschraube ist die gegenüber der Grundplatte verschwenkbare Führungssäule festlegbar. Dabei durchsetzt die Spannschraube eine Bohrung der Rasterplatte sowie ein Langloch in einem der beiden Lagerböcke und wirkt mit einem entsprechenden Gewinde in der Führungssäule zusammen.For drilling holes in hard surfaces, such as concrete, Rock or the like are used drilling rigs that are used in certain Requirements, especially regarding the quality of the borehole to be produced, with the help of a stand must be guided during the drilling process. Such a stand is known for example from DE-U-297 13 139. This stand sits down together from a base plate having a support surface, two bearing blocks, a grid plate, a guide column and an axially displaceable locking element. The two bearing blocks and the grid plate are arranged on the base plate and protrude from it. A pivot axis around which the guide column is opposite the Base plate is pivotable, extends through both bearing blocks and the Guide column. The grid plate has several, for example at the same angles spaced apart bores on one around the pivot axis running circular path are arranged. With the help of the locking element in shape A clamping screw is the guide column that can be swiveled in relation to the base plate fixable. The clamping screw penetrates a hole in the grid plate as well Elongated hole in one of the two pedestals and acts with a corresponding thread together in the guide pillar.
Eine schnelle Änderung der Neigung der Führungssäule gegenüber der Grundplatte kann mit diesem bekannten Ständer nicht durchgeführt werden, da das Verriegelungselement - die Spannschraube - erst mühsam ein Stück weit herausgedreht werden, bis ein zylindrischer Abschnitt der Spannschraube, nach einem Schwenkvorgang der Führungssäule, in einer anderen Bohrung der Rasterplatte wieder eingesetzt werden kann. A quick change in the inclination of the guide column relative to the base plate can not be carried out with this known stand, since the locking element - the tensioning screw - first unscrewed a little bit until a cylindrical section of the clamping screw, after a swiveling of the Guide column, to be reinserted in another hole in the grid plate can.
Der Erfindung liegt die Aufgabe zugrunde, einen Ständer für ein Bohrgerät zu schaffen, bei dem die Neigung der Führungssäule gegenüber der Grundplatte sehr schnell, einfach und mit wenigen Handgriffen sowie werkzeuglos verändert werden kann. Der Ständer soll stabil ausgebildet sein und und es soll die Neigung der Führungssäule auch dann veränderbar sein, wenn der Ständer an schwer zugänglichen Stellen verwendet wird, an denen seitlich neben dem Ständer sehr wenig freier Arbeitsraum vorhanden ist.The invention has for its object to provide a stand for a drill, where the inclination of the guide column relative to the base plate is very quick, easy and can be changed in a few simple steps and without tools. The stand should be stable and and the inclination of the guide column should then also be changeable if the stand is used in hard-to-reach places which has very little free work space to the side of the stand.
Die Lösung dieser Aufgaben erfolgt mit einem Ständer der gattungsbildenden Bauart für ein Bohrgerät, der die im
kennzeichnenden Teil des Patentanspruchs 1 angeführten Merkmale aufweist.These tasks are solved with a stand of the generic type for a drilling rig, which in the
characterizing part of
Mit Hilfe des erfindungsgemässen Verriegelungsschiebers und der Spannvorrichtung lässt sich eine einfache und schnelle Freigabe bzw. Festlegung der Führungssäule gegenüber der Grundplatte erreichen.With the help of the locking slide according to the invention and the tensioning device the guide column can be released quickly and easily reach opposite the base plate.
Um die Neigung der Führungssäule gegenüber der Grundplatte sehr schnell und einfach verändern zu können, erfolgt beispielsweise die Versetzung des Verriegelungsschiebers in eine Freigabestellung mit Hilfe der Spannvorrichtung, die von einer Bedienungsperson beispielsweise in Richtung Grundplatte bewegt wird.To the inclination of the guide column relative to the base plate very quickly and easily To be able to change, for example, the locking slide is moved in a release position with the help of the tensioning device by an operator for example in the direction of the base plate.
Damit die Bewegung der Spannvorrichtung bei einem Versetzen derselben in Richtung Grundplatte in eine parallel zu einer Auflagefläche der Grundplatte verlaufende Bewegung umgelenkt werden kann, bei der eine Versetzung des Verriegelungsschieber erfolgt, weist die Spannvorrichtung wenigstens einen in Richtung Grundplatte abragenden, eine Durchtrittsöffnung des Verriegelungsschiebers durchsetzenden Transportarm auf, der sich mit zunehmender Erstreckung in Richtung Grundplatte immer mehr der Rasterplatte nähert.So that the movement of the clamping device when it is moved in the direction Base plate in a parallel to a support surface of the base plate Movement can be redirected, in which an offset of the locking slide takes place, the clamping device has at least one in the direction of the base plate protruding, penetrating a passage opening of the locking slide Transport arm on, which always with increasing extension towards the base plate closer to the grid plate.
Vorteilhafterweise dient der Aufnahme und Führung sowohl der Spannvorrichtung als auch des Verriegelungsschiebers eine Führungsleiste, die von einer der Auflagefläche gegenüberliegenden Seite der Grundplatte abragt. Diese Führungsleiste ist einfach herstellbar und für die Bedienungsperson gut zugänglich, so dass die Montage sowohl des Verriegelungsschiebers als auch der Spannvorrichtung in einer sehr kurzen Zeit erfolgen kann.Advantageously, the mounting and guiding of both the clamping device and also the locking slider has a guide bar that extends from one of the bearing surface protrudes opposite side of the base plate. This guide bar is simple producible and easily accessible for the operator, so that the assembly both of the locking slide and the clamping device in a very short time can be done.
Um eine gute Führung der Spannvorrichtung erreichen zu können, weist zweckmässigerweise die Führungsleiste wenigstens zwei sacklochartig ausgebildete Führungsbohrungen auf, in die der Transportarm und ein Führungsarm der Spannvorrichtung ragt.In order to be able to achieve good guidance of the tensioning device, expediently points the guide bar has at least two blind holes Guide holes in which the transport arm and a guide arm of the Clamp protrudes.
Vorzugsweise ist zwischen dem Transportarm und dem Grund jener Führungsbohrung, in die der Transportarm ragt ein Federelement angeordnet. Dieses Federelement dient der Rückstellung der Spannvorrichtung in ihre Ausgangsstellung. Wenn sich die Spannvorrichtung in der Ausgangsstellung befindet, befindet sich der Verriegelungsschieber in der Verriegelungsstellung.Preferably between the transport arm and the bottom of that guide hole, in which the transport arm protrudes arranged a spring element. This spring element serves the Reset the tensioning device to its initial position. If the jig is in the starting position, the locking slide is in the locking position.
Aus montagetechnischen Gründen dienen vorzugsweise der Abstützung des Verriegelungsschiebers in einer von der Auflagefläche der Grundplatte abgewandten Richtung zwei voneinander beabstandete Führungsbleche, die lösbar mit der Führungsleiste in Verbindung stehen. Diese beiden Führungsbleche decken den Verriegelungsschieber beispielsweise teilweise ab und wirken formschlüssig mit der von der Grundplatte abragenden Führungsleiste zusammen.For assembly reasons, the support of the Locking slide in one facing away from the support surface of the base plate Direction two spaced guide plates that are detachable with the guide bar stay in contact. These two guide plates cover the locking slide for example, partially and act positively with that of the base plate protruding guide bar together.
Zweckmässigerweise weist der Ständer zwei voneinander beabstandete Führungssäulen auf, an deren einander zugewandten Innenseiten eine Rasterplatte angeordnet ist und das Verriegelungselement ist von zwei Verriegelungsschiebern gebildet, die zwischen den Rasterplatten sowie an der Grundplatte zueinander koaxial angeordnet sind. Zusammen mit der Grundplatte verleihen die beiden Führungssäulen dem erfindungsgemässen Ständer eine sehr hohe Steifigkeit. Eine besonders gute Festlegung eines zwischen den Führungssäulen und der Grundplatte eingestellten Winkels wird mit beiden Verriegelungsschiebern erreicht, die zwischen beiden Führungssäulen angeordnet sind und formschlüssig mit den beiden, an den Führungssäulen angeordneten, Rasterplatten in Verbindung bringbar sind.The stand expediently has two guide columns which are spaced apart from one another on the inside of which a grid plate is arranged and the locking element is formed by two locking slides between the Grid plates and coaxially arranged on the base plate. Together with the base plate, the two guide columns lend the invention Stand a very high rigidity. A particularly good definition of one between the Guide columns and the base plate set angle with both Locking slides reached, which are arranged between the two guide columns and form-fitting with the two grid plates arranged on the guide columns are connectable.
Damit der Ständer auch an schwer zugänglichen Stellen verwendet werden kann, an denen seitlich neben dem Ständer sehr wenig freier Arbeitsraum vorhanden ist, erfolgt zweckmässigerweise die koaxiale Versetzung der beiden Verriegelungsschieber mit einer zwischen den Verriegelungsschiebern und somit auch zwischen den Führungssäulen angeordneten Spannvorrichtung.So that the stand can also be used in places that are difficult to access which has very little free work space to the side of the stand expediently the coaxial displacement of the two locking slides with one between the locking slides and thus also between the guide columns arranged clamping device.
Um beide Verriegelungsschieber koaxial zueinander versetzen zu können weist vorzugsweise die Spannvorrichtung zwei in Richtung Grundplatte abragende, jeweils eine Durchtrittsöffnung der beiden Verriegelungsschieber durchsetzende Transportarme auf, deren Abstand voneinander mit zunehmender Erstreckung in Richtung Grundplatte zunimmt.In order to be able to offset both locking slides coaxially to one another preferably the clamping device protrudes two in the direction of the base plate, one each Opening of the two locking slides passing through transport arms, their distance from one another with increasing extension in the direction of the base plate increases.
Aufgrund der erfindungsgemässen Ausgestaltung des Ständers ist eine Bedienungsperson in der Lage mit nur einem kurzen Druck auf die Spannvorrichtung die Verriegelungsschieber in eine Freigabestellung zu versetzen. Beim anschliessenden Verschwenken der Führungssäule liegen die den Durchtrittsöffnungen gegenüberliegenden, freien Enden der Verriegelungsschieber seitlich an den Rasterplatten an. Sobald diese freien Enden wiederum in Überdeckung mit der jeweils nachfolgenden Bohrung in beiden Rasterplatten gebracht werden, drücken die Federelemente die Spannvorrichtung zurück in ihre Ausgangsstellung und die Verriegelungsschieber in die Verriegelungsstellung.Due to the design of the stand according to the invention, it is an operator able with just a short press on the jig To put the locking slide in a release position. At the subsequent one Swiveling the guide column lies opposite the passage openings free ends of the locking slide on the side of the grid plates. Once these free ends in turn overlap with the next one Bore are brought in both grid plates, the spring elements press the Clamping device back to its starting position and the locking slide in the Locking position.
