Description

Die Neuerung betrifft ein Gerät zum Räumen von auf einem Untergrund verstreuten explosiven Gegenständen nach dem Oberbegriff des Patentanspruchs 1. Ein derartiges Gerät ist in der FR-A-914 285 beschrieben.The innovation relates to a device for clearing explosive objects scattered on a surface according to the preamble of claim 1. Such a device is described in FR-A-914 285.

Start- und Landebahnen in zivilen oder militärischen Flughäfen, Strassen und andere Flächen können durch einen feindlichen Angriff dadurch stillgelegt werden, dass sie mit kleinen Bomben oder Minen bestreut werden, deren Zündung auf unterschiedliche physikalische Erscheinungen anspricht, wie zum Beispiel mechanische Belastung, Annäherung, Schall usw. Es erfordert ein zu hohes Risiko und ist häufig auch zu zeitraubend, derartige explosive Gegenstände durch menschlichen Einsatz zu räumen.Runways in civil or military airports, roads and other areas can be shut down by an enemy attack by sprinkling them with small bombs or mines, the ignition of which responds to different physical phenomena, such as mechanical stress, approach, sound etc. It takes too much risk and is often too time consuming to clear such explosive objects through human effort.

Räumgeräte für Explosivkörper sind bekannt.Broaching devices for explosive devices are known.

So geht aus der FR-A-914 285 ein Räumgerät für verstreute Explosivkörper, wie Sprengkörper, Bomben, Minen o.dgl. hervor, bei dem an einem motorisch angetriebenen Fahrzeug eine in der Höhe verstellbare Räumschaufel angeordnet ist. Diese Räumschaufel dient dabei als Erdbewegungsorgan, d.h. dazu, in das Erdreich einzudringen, um mehr oder weniger grosse Explosivkörper aus dem Erdreich zu befördern. Mit einer derartigen Räumschaufel kann also ein grösserer Explosivkörper aus dem Erdreich herausbefördert, nicht aber eine grössere Anzahl von Explosivkörpern gesammelt und abtransportiert werden. Alternativ zur Räumschaufel kann dieses Räumgerät eine Art Fräswalze mit einer Reihe von radialen Zinken aufweisen. Diese Zinken dringen wiederum in den Erdboden ein, um Explosivkörper aus diesem an die Oberfläche zu befördern. Auch diese Fräswalze ist nicht geeignet, auf der Oberfläche des Erdreichs liegende Gegenstände aufzunehmen, geschweige zu sammeln und abzutransportieren.FR-A-914 285 is a clearing device for scattered explosive devices such as explosive devices, bombs, mines or the like. out, in which a height-adjustable clearing blade is arranged on a motor-driven vehicle. This scraper serves as an earth moving device, i.e. to penetrate into the ground in order to remove more or less large explosive devices from the ground. With a clearing vane of this type, a larger explosive body can therefore be transported out of the ground, but a larger number of explosive bodies cannot be collected and transported away. As an alternative to the clearing blade, this clearing device can have a type of milling drum with a row of radial tines. These tines in turn penetrate the ground to bring explosives to the surface. This milling drum is also not suitable for picking up objects on the surface of the ground, let alone collecting them and transporting them away.

Aus der GB-A-2027096 geht ein mit einer Baggerschaufel und einer zugeordneten Fräswalze aufgebautes Erdbewegungsgerät hervor. Die Fräswalze dient dazu, das Erdreich zu lockern, so dass es von der Schaufel durch Anheben mitgenommen werden kann. Auch bei diesem Gerät ist es nicht möglich, mit Hilfe der Fräswalze auf dem Boden liegende Gegenstände zu erfassen und in die Baggerschaufel hineinzustreichen, d.h. verstreute Explosivkörper aufzusammeln.GB-A-2027096 discloses an earth moving device constructed with an excavator bucket and an associated milling drum. The milling drum serves to loosen the soil so that it can be lifted by the bucket. With this device, too, it is not possible to use the milling drum to detect objects lying on the ground and to sweep them into the excavator bucket, i.e. to collect scattered explosive devices.

Aus der US-A-3 878 952 geht ebenfalls ein Erdbewegungsgerät hervor, welches eine Schaufel und eine Fräswalze aufweist. Die Fräswalze ist so angeordnet, dass Erdreich von oben nach unten abgetragen werden kann und zwar derart, dass es in die darunter befindliche Schaufel hineinfällt. Wie bereits beim vorgenannten Stand der Technik ist auch dieses Gerät nicht geeignet, auf dem Boden verstreut liegende explosive Gegenstände aufzunehmen und abzutransportieren.From US-A-3 878 952 there is also an earth moving device which has a shovel and a milling drum. The milling drum is arranged so that soil can be removed from top to bottom in such a way that it falls into the shovel underneath. As with the aforementioned prior art, this device is also unsuitable for picking up and carrying away explosive objects scattered on the floor.

Ferner geht aus der AT-A-354 346 eine einen Zinken enthaltende Schaufel mit einem parallel zum Erdreich zu bringenden Abschnitt hervor, um Gegenstände wie z.B. Steine, Kartoffeln, Rüben etc. aufzulesen. Die bei diesem Gerät der Schaufel zugeordnete Walze ist jedoch eine sogenannte Krümelwalze, mit welcher Erdreich von den Gegenständen entfernt und zerkleinert wird, um anschliessend durch die Zinken auf den Erdboden zurückzufallen. Mit Hilfe einer derartigen Walze ist es ebenfalls nicht möglich, die aufzulesenden Gegenstände in die Schaufel hineinzustreichen.Furthermore, AT-A-354 346 discloses a shovel containing a prong with a section to be brought parallel to the ground in order to hold objects such as e.g. Picking up stones, potatoes, beets etc. However, the roller assigned to the shovel in this device is a so-called crumb roller, with which soil is removed from the objects and shredded, in order to then fall back to the ground through the tines. With the help of such a roller, it is also not possible to brush the objects to be read into the blade.

Im übrigen weisen die drei zuletzt genannten Gegenstände keinerlei Schutz gegenüber einer beim Räumen u.U. möglichen Detonation eines Explosivkörpers auf.Incidentally, the last three items have no protection against one when clearing. possible detonation of an explosive device.

Der Neuerung liegt daher die Aufgabe zugrunde, ein Gerät zum Räumen von auf einem Untergrund verstreuten explosiven Gegenständen wie Sprengkörper, Bomben, Minen oder dergleichen, insbesondere auf Start- und Landebahnen in Flughäfen zu schaffen, mit dem einfach und innerhalb kurzer Zeit gefahrlos grössere Flächen von derartigen Gegenständen geräumt werden können.The innovation is therefore based on the task of creating a device for clearing explosive objects scattered on a surface, such as explosive devices, bombs, mines or the like, in particular on airport runways, with which larger areas of easily and within a short period of time can be safely and without danger such objects can be cleared.

Die Lösung dieser Aufgabe wird erfindungsgemäss durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst.This object is achieved according to the invention by the characterizing features of patent claim 1.

Am neuerungsgemässen Fahrzeug ist eine Räumschaufel angebracht, die zumindest in der Höhe verstellbar ist. Die Räumschaufel kann daher im Gebrauch relativ nahe an die Oberfläche des zu räumenden Untergrunds gebracht werden, wobei sich der vordere Abschnitt der Schaufel annähernd parallel zum Untergrund erstreckt. Das besenförmige Räumorgan führt eine zum Schaufelinnern gerichtete Streichbewegung aus und erfasst dabei vor der Schaufel befindliche Gegenstände und schiebt sie in das Schaufelinnere. Dort verbleiben sie und können an einen anderen Ort verbracht werden. Das Fahrzeug, an dem die Räumschaufel angebracht ist, kann ein übliches Rad-Nutzfahrzeug sein. Es versteht sich jedoch, dass zumindest die Flächen des Fahrzeugs, die im Bereich der Räumschaufel liegen, eine Panzerung aufweisen, damit es bei Explosionen nicht zu stark beschädigt wird. Ferner muss der Fahrer des Fahrzeugs ausreichend gegen Explosionswirkungen geschützt sein. Es versteht sich ferner, dass die Räumschaufel entsprechend stabil ausgeführt ist, damit sie bei Explosionen nicht gebrauchsunfähig wird.A clearing shovel is attached to the vehicle according to the innovation and is adjustable at least in height. The clearing vane can therefore be brought relatively close to the surface of the subsurface to be cleared in use, the front section of the vane extending approximately parallel to the subsurface. The broom-shaped broaching element executes a sweeping movement directed towards the interior of the blade and thereby detects objects in front of the blade and pushes them into the interior of the blade. They remain there and can be moved to another location. The vehicle on which the clearing vane is attached can be a conventional wheeled utility vehicle. However, it goes without saying that at least the surfaces of the vehicle which are in the area of the clearing vane have armor so that it is not damaged too severely in the event of explosions. The driver of the vehicle must also be adequately protected against the effects of explosions. It also goes without saying that the clearing vane is designed to be sufficiently stable so that it does not become unusable in the event of an explosion.

Es sind verschiedene Konstruktionen denkbar, um mit Hilfe eines besenförmigen Räumorgans das Hineinstreichen der zu räumenden Gegenstände in die Räumschaufel zu bewerkstelligen. Vorzugsweise wird ein umlaufendes Räumorgan verwendet, insbesondere nach einer Ausgestaltung der Erfindung eine Besenwalze.Various constructions are conceivable for using a broom-shaped clearing device to bring the objects to be cleared into the clearing scoop. A circumferential broaching device is preferably used, in particular a broom roller according to an embodiment of the invention.

Um ein optimales Zusammenwirken von Räumschaufel und besenförmigem Räumorgan zu erzielen, sieht eine weitere Ausgestaltung der Neuerung vor, dass das besenförmige Räumorgan relativ zur Räumschaufel höhenverstellbar gelagert ist. Dies kann bei einer Besenwalze nach einer weiteren Ausgestaltung der Neuerung dadurch geschehen, dass die Besenwalze in einer Schwinge gelagert ist, die im oberen Bereich der annähernd L-förmigen Räumschaufel angelenkt ist. Für die Verstellung der Schwinge kann einIn order to achieve an optimal interaction of the clearing scoop and the broom-shaped clearing member, a further embodiment of the innovation provides that the broom-shaped clearing member is mounted such that it can be adjusted in height relative to the clearing scoop. In a broom roller according to a further embodiment of the innovation, this can be done in that the broom roller is mounted in a rocker arm which is articulated in the upper region of the approximately L-shaped clearing blade. A can be used to adjust the swing arm

Hydraulikzylinder dienen. Auch für den Antrieb der Besenwalze bieten sich verschiedene Lösungen an. Eine besteht neuerungsgemäss darin, dass an der Schwinge ein Hydraulikmotor zum Antrieb für die Besenwalze angeordnet ist.Serve hydraulic cylinders. Various solutions are also available for driving the broom roller. According to the innovation, one is that a hydraulic motor for driving the broom roller is arranged on the rocker arm.

Damit das die Räumwerkzeuge haltende Fahrzeug auch zu anderen Zwecken eingesetzt werden kann, ist es nach einer weiteren Ausgestaltung der Neuerung vorteilhaft, wenn die Räumschaufel und das Räumorgan als Räumeinheit lösbar mit einem höhenverstellbaren Schwenkarm des Fahrzeugs verbindbar sind. An dem Schwenkarm können wahlweise auch Werkzeuge für Erdarbeiten, zum Heben und Tragen von Lasten usw. angebracht werden.So that the vehicle holding the broaching tools can also be used for other purposes, it is advantageous according to a further embodiment of the innovation if the broaching blade and the broaching member as a broaching unit can be releasably connected to a height-adjustable swivel arm of the vehicle. Tools for earthwork, lifting and carrying loads, etc. can also be attached to the swivel arm.

Damit im Fall einer Explosion die Druckwirkung keine erheblichen Beschädigungen an der Räumschaufel erzeugt, ist diese möglichst offen auszuführen. Sie weist daher zweckmässigerweise keine Seitenwände auf. Sie ist ferner bei einer Ausgestaltung der Neuerung mit einer Reihe von parallelen Zinken versehen. Dadurch kann die Druckwelle im Fall einer Explosion sich auch nach unten ausbreiten.To ensure that the pressure effect does not cause significant damage to the clearing vane in the event of an explosion, it must be carried out as openly as possible. It therefore expediently has no side walls. In one embodiment of the innovation, it is also provided with a series of parallel tines. This means that the pressure wave can spread downwards in the event of an explosion.

Die Neuerung wird nachfolgend anhand eines Ausführungsbeispiels näher erläutert.

Bevor auf die in den Zeichnungen dargestellten Einzelheiten näher eingegangen wird, sei vorangestellt, dass jedes der beschriebenen Merkmale für sich oder in Verbindung mit Merkmalen der Ansprüche von neuerungswesentlicher Bedeujung ist.Before going into the details shown in the drawings, it should be assumed that each of the described features, by itself or in conjunction with features of the claims, is of importance for innovation.

Ein Radfahrzeug 10 besitzt an einem Ende einen Z-förmigen Schwenkarm 11, der aus parallelen Armteilen besteht. Die Armteile sind auf einem Lagerbauteil 12 bei 13 angelenkt. Mit Hilfe eines Hydraulikzylinders 14 kann der Schwenkarm angehoben bzw. abgesenkt werden. Das Lagerbauteil 12 ist ausserdem um eine vertikale Achse verschwenkbar. Ein am Lagerbauteil 12 angelenkter Hydraulikzylinder 15 ist an dem anderen Ende an einen Hebel 16 angelenkt, der wiederum doppelt ausgeführt sein kann. Am anderen Ende des Hebels greift eine Lenkstange 17 an. Der Hebel 16 ist bei 18 zwischen den Teilen des Schwenkarms 11 drehbar gelagert. Die Lenkstange 17 ist am anderen Ende bei 19 an einem Haltebauteil 20 gelagert, das seinerseits bei 21 am unteren Ende des Schwenkarms 11 angelenkt ist. Das Haltebauteil 20 dient zur lösbaren Aufnahme einer Räumeinheit 22, deren Einzelheiten anhand von Fig. 2 näher beschrieben werden.A wheeled vehicle 10 has a Z-shaped swivel arm 11 at one end, which consists of parallel arm parts. The arm parts are articulated on a bearing component 12 at 13. With the help of a hydraulic cylinder 14, the swivel arm can be raised or lowered. The bearing component 12 is also pivotable about a vertical axis. A hydraulic cylinder 15 articulated on the bearing component 12 is articulated at the other end to a lever 16, which in turn can be designed in duplicate. At the other end of the lever, a handlebar 17 engages. The lever 16 is rotatably supported at 18 between the parts of the swivel arm 11. The handlebar 17 is mounted at the other end at 19 on a holding component 20 which in turn is articulated at 21 at the lower end of the swivel arm 11. The holding component 20 serves to releasably receive a clearing unit 22, the details of which are described in more detail with reference to FIG. 2.

Die Räumeinhait 22 weist eine Räumschaufel 23 und ein besenartiges Räumorgan 24 auf. Die Räumschaufel 23 ist annähernd L-förmig geformt. Der Querschenkel besteht aus einer Reihe von parallelen Zinken 25, die am hinteren Ende an der geschlossenen Rückwand 26 angebracht sind. Die Rückwand 26 schliesst mit den Zinken 25 einen Winkel ein, der kleiner als 90° ist. Die Rückwand 26 wird durch zwei parallele U-förmige Träger 27, 28 verstärkt. Ein weiterer annähernd U-förmiger Träger 29 verstärkt die sich im unteren Bereich abknickende Rückwand 26. Ferner nimmt er die Hauptlast der Zinken 25 auf. An zwei parallelen Blechen, von denen eines bei 30 gezeigt ist und die an der Rückseite der Rückwand 26 annähernd im rechten Winkel angebracht sind, sind eine Öse 31 und ein Zapfen 32 vorgesehen. Die Öse 31 greift in einen entsprechenden Zapfen des Haltebauteils 20, während der Zapfen 32 von einer Klinke des Haltebauteils 20 umfasst wird. Beide Befestigungsteile am Haltebauteil 20 sind nicht dargestellt. Man erkennt jedoch, dass auf diese Weise die Einheit 22 lösbar am Haltebauteil 20 befestigt werden kann.The clearing unit 22 has a clearing blade 23 and a broom-like clearing member 24. The clearing blade 23 is shaped approximately L-shaped. The cross leg consists of a series of parallel tines 25 which are attached at the rear end to the closed rear wall 26. The rear wall 26 forms an angle with the prongs 25 which is less than 90 °. The rear wall 26 is reinforced by two parallel U-shaped supports 27, 28. Another approximately U-shaped support 29 reinforces the rear wall 26 that kinks in the lower region. It also absorbs the main load of the tines 25. An eyelet 31 and a pin 32 are provided on two parallel sheets, one of which is shown at 30 and which are attached to the rear of the rear wall 26 at approximately a right angle. The eyelet 31 engages in a corresponding pin of the holding component 20, while the pin 32 is encompassed by a pawl of the holding component 20. Both fastening parts on the holding component 20 are not shown. However, it can be seen that in this way the unit 22 can be detachably attached to the holding component 20.

Die Zinken 25 sind am vorderen Ende im Querschnitt dreieckförmig verjüngt, wie bei 33 dargestellt. Sie weisen ausserdem eine dreieckförmige Erhebung 34 auf, die dazu dient, aufgenommene Gegenstände an einem Herausrutschen oder -rollen zu hindern. Die Zinken an den beiden Seiten sind etwas höher ausgeführt als die dazwischenliegenden, wie bei der Zinke 35 zu erkennen. Sie verhindern ein seitliches Herausfallen aufgenommener Gegenstände.The tines 25 are tapered triangular in cross section at the front end, as shown at 33. They also have a triangular elevation 34, which serves to prevent picked up objects from slipping out or rolling. The tines on both sides are slightly higher than the ones in between, as can be seen in the tine 35. They prevent objects picked up from falling out to the side.

An der Rückwand 26 sind zwei beabstandete nach oben weisende Konsolen angebracht, von denen eine bei 36 dargestellt ist. An den Konsolen 36 sind Arme einer Schwinge bei 37 angelenkt, von denen ein Arm bei 38 dargestellt ist. Die Arme 38 sind durch ein rohrförmiges Verbindungselement 39 gegenseitig abgestützt. Zwischen den Armen 38 ist eine Besenwalze 40 drehbar gelagert, die von einem am Arm 38 gehaltenen Hydraulikmotor 41 in Drehung gesetzt werden kann, und zwar in Richtung des Pfeils 42. Wie erkennbar, ist der Aussendurchmesser der Besenwalze so bemessen, dass die Besenwalze etwas an der Oberseite der Zinkenspitze 33 entlangstreicht.On the rear wall 26 are two spaced upwardly facing brackets, one of which is shown at 36. Arms of a rocker are articulated to the brackets 36 at 37, one arm of which is shown at 38. The arms 38 are mutually supported by a tubular connecting element 39. A broom roller 40 is rotatably mounted between the arms 38 and can be rotated by a hydraulic motor 41 held on the arm 38, in the direction of the arrow 42. As can be seen, the outer diameter of the broom roller is dimensioned such that the broom roller is slightly on sweeps along the top of tine tip 33.

Ein nach innen weisender seitlicher Ansatz 43 am Arm 38 weist einen Anschlag 44 auf in Form einer auf einen Schraubenbolzen geschraubten Mutter. An der Rückwand 26 ist ein Anschlag 45 angebracht in Form eines Schraubenbolzens mit aufgeschraubter Mutter. Die Anschläge 44, 45 bestimmen die untere Arbeitsposition der Besenwalze 40. Durch Verstellen der Muttern kann die Relativlage der Besenwalze 44 zu den Zinken 25, 35 verändert werden. Zweckmässigerweise ist die Besenwalze 40 so bemessen, dass die Zinken 35 sich neben der Walze erstrecken.An inwardly facing side extension 43 on the arm 38 has a stop 44 in the form of a nut screwed onto a screw bolt. On the rear wall 26 a stop 45 is attached in the form of a screw bolt with a nut screwed on. The stops 44, 45 determine the lower working position of the broom roller 40. By adjusting the nuts, the relative position of the broom roller 44 to the prongs 25, 35 can be changed. The broom roller 40 is expediently dimensioned such that the tines 35 extend next to the roller.

Ist die Räumeinheit 22 nach Fig. 1 vom Haltebauteil 20 des Schwenkarms 11 aufgenommen, kann die Schaufel 23 so verschwenkt und abgesenkt werden, dass die Unterseite der Zinken 25, 35 annähernd parallel und in geringem Abstand zum Untergrund verlaufen. Wird das Fahrzeug 10 in Richtung des Pfeils 46 bewegt und die Besenwalze 40 in Umlauf gesetzt, können auf dem Untergrund befindliche explosive Gegenstände mit Hilfe der Besenwalze 40 auf die Oberseite der Zinken 25 gefördert werden. Es ist daher möglich, innerhalb kurzer Zeit grosse Flächen von explosiven Gegenständen, wie Bomben oder Minen zu räumen. Nach Beendigung des Räumvorgangs bzw. bei gefüllter Räumschaufel 23 wird der Schwenkarm 11 angehoben. Die aufgenommenen Gegenstände können dann an einen anderen Ort verbracht werden.If the clearing unit 22 according to FIG. 1 is received by the holding component 20 of the swivel arm 11, the blade 23 can be pivoted and lowered so that the underside of the prongs 25, 35 run approximately parallel and at a short distance from the ground. If the vehicle 10 is moved in the direction of the arrow 46 and the broom roller 40 is put into circulation, explosive objects located on the ground can be conveyed onto the top of the prongs 25 with the aid of the broom roller 40. It is therefore possible to close large areas of explosive objects such as bombs or mines within a short time vacate. After the broaching process or when the broach 23 is filled, the swivel arm 11 is raised. The recorded objects can then be moved to another location.

Aus Fig. 1 ist schliesslich ersichtlich, dass die Arme 38 der Schwinge mit Hilfe eines Hydraulikzylinders 47 verschwenkbar ist. Die Besenwalze 40 muss gegenüber der Schaufel 23 nach oben verschwenkt werden, damit die Schaufel 23 entladen werden kann.1 finally shows that the arms 38 of the rocker can be pivoted with the aid of a hydraulic cylinder 47. The broom roller 40 must be pivoted upward relative to the blade 23 so that the blade 23 can be unloaded.
