Description

Die Erfindung bezieht sich auf ein Fahrzeug zum Transportieren eines Stapels loser Steine, das ein Gestell, welches von zwei Vorderrädern und wenigstens einem Hinterrad getragen wird, auf diesem Gestell montierte Mittel zum Antrieb von mindestens den Vorderrädern, eine sich vor den Vorderrädern befindlichen, bewegbar auf dem Gestell montierte Einrichtung zur tragen der Steine,-welche Einrichtung zwei vorwärts ausregende und seitwärts auseinander und zueinander verstellbare Arme zum Einklemmen dazwischen einer oder mehrerer sich unten am Stapel befindlichen Reihen Steine - und Mittel um diese Arme seitwärts gegenüber einander zu verstellen umfasst, und Mittel zum bewegen dieser Einrichtung umfasst.The invention relates to a vehicle for transporting a stack of loose stones, the frame, which is supported by two front wheels and at least one rear wheel, movably mounted on this frame for driving at least the front wheels, one in front of the front wheels the frame-mounted device for supporting the stones, which means comprises two arms which move forward and are laterally apart and adjustable relative to one another for clamping between one or more rows of stones located at the bottom of the stack, and means for moving these arms laterally relative to one another, and means to move this facility includes.

Beim Pflastern mit Steinen, insbesondere mit klinkern, macht man gewöhnlich erst ein genau flach gestrichenes Bett aus Sand, worauf man die Steine gegeneinander legt. Die Steine werden von Lastwagen mit Hilfe von kränen oder dgl. in grossen zusammengebundenen Stapeln hingesetzt. Man löst die Stapel, und kleinere Stapel loser steine, welche also Teile dieser grossen Stapel bilden, werden an Ort und Stelle gebracht, manchmal sogar über die bereits gelegten Steine.When paving with stones, especially with clinker, you usually first make a bed of sand that is painted exactly flat, after which you place the stones against each other. The stones are put down by trucks with the help of cranes or the like in large tied stacks. The stacks are loosened, and smaller stacks of loose stones, which thus form part of these large stacks, are brought in place, sometimes even over the stones already laid.

Meistens findet dies noch vollständig manuell statt, z.B. mit Hilfe einer Schubkarre, worin die Steine von Hand eingelegt werden und die nachher zur Stelle ausgeschüttet wird. Dies ist selbstverständlich sehr zeitraubend und arbeitsintensiv.Most of the time, this is still completely manual, e.g. with the help of a wheelbarrow, in which the stones are inserted by hand and which is then poured out on the spot. Of course, this is very time consuming and labor intensive.

In einigen Fällen wird bereits ein Fahrzeug des fraglichen Typs verwendet.In some cases, a vehicle of the type in question is already being used.

Ein solches Fahrzeug ist bekannt aus US-A-2 836317.Such a vehicle is known from US-A-2 836317.

Die Einrichtung zum Tragen von Stein ist vertikal verschiebar auf einem Masten der selbst ein Wenig kantelbar ist hinsichtlich des übrigen des Gestells, montiert. Diese Konstruktion ermöglicht wohl eine Grosse höhenweise Versetzung der Steine, aber sie ist kompliziert und keinerweise kompakt. Die Versetzung der Steine findet normalerweise rein vertikal statt, ohne dass ein Stutz an der hinteren Seite der Einrichtung zum Tragen benötigt wird.The device for carrying stone is vertically slidably mounted on a mast which itself can be tilted a little with respect to the rest of the frame. This construction allows the stones to be displaced in large heights, but it is complicated and by no means compact. The stones are usually moved vertically without the need for a support on the rear side of the device.

GB-A-965 601 beschreibt eine Einrichtung zum Tragen von Steinen die wohl einem geradestehenden Rückenwand besitzt, aber auch in diesem Fall ist die Einrichtung bestimmt um nur vertikal schiebar auf einen Masten montiert zu werden. Diese Einrichtung umfasst zudem kein Paar verstellbare Arme aber Gabelfinger und der Rückenwand bildet vor allem einen Anschlag für die Steine wann die Gabelfinger durch Öffnungen in einen Stapel Steine gesteckt werden.GB-A-965 601 describes a device for carrying stones which probably has a standing back wall, but also in this case the device is intended to be mounted only vertically slidably on a mast. This device also does not include a pair of adjustable arms, but fork fingers and the back wall primarily form a stop for the stones when the fork fingers are inserted through openings in a stack of stones.

Gegenstand dieser Erfindung ist es, diesen Nachteilen abzuhelfen und ein Fahrzeug zum Transport eines Stapels loser Steine zu verschaffen, das eine Verhältnismässig einfache Konstruktion hat, aber mit dem sehr schnell Stapel loser Steine transportiert werden können, das ausserdem sehr leicht ausgeführt werden kann und ohne Gefahr der Beschädigung der bereits verlegten Pflasterung darüber fahren kann.The object of this invention is to remedy these disadvantages and to provide a vehicle for transporting a stack of loose stones, which has a relatively simple construction, but can be transported very quickly with the stack of loose stones, which can also be carried out very easily and without danger damage to the pavement already laid can drive over it.

Zu diesem Zweck ist die Einrichtung zur tragen der Steine ein Steinbehälter und besitzt sie ausser den Armen und den Mitteln auch eine sich an der Rückseite der Arme, vor den Vorderrädern, von unten nach oben ausstreckende, fast flache Stütze und um eine Horizontalachse unmittelbar drehbar auf dem Gestel montiert, wobei die Stütze bei gedrehtem Stand des Behälters schräg nach oben und nach hinten gerichtet ist, um die zwischen den Armen eingeklemmtenReihen Steine und darüber gelegenen Reihen Steine zu unterstützen.For this purpose, the device for carrying the stones is a stone container and, in addition to the arms and means, it also has an almost flat support which extends from the bottom to the rear of the arms, in front of the front wheels, and can be rotated directly about a horizontal axis mounted on the frame, the support being directed obliquely upwards and backwards when the container is rotated, in order to support the rows of stones clamped between the arms and rows of stones lying above them.

Nach einer besonderen Ausfuhrungsweise der Erfindung ist der Behälter drehbar gegenüber dem gestell um eine Horizontalachse, die sich auf einem gewissen Abstand ruckwärts davon befindet.According to a special embodiment of the invention, the container is rotatable relative to the frame about a horizontal axis, which is at a certain distance backwards from it.

Vorzugsweise befindet sich die Achse in der Nähe der Drehachse der Vorderräder.The axle is preferably located in the vicinity of the axis of rotation of the front wheels.

Nach einer wirksamen Ausführungsweise der Erfindung sind die Vorderräder starr gegenüber dem Gestell und sind die Mittel, um mindestens die Vorderräder anzutreiben, Mittel um die zwei Vorderräder gesondert anzutreiben.According to an effective embodiment of the invention, the front wheels are rigid with respect to the frame and the means for driving at least the front wheels are means for driving the two front wheels separately.

Vorugsweise ist überdies das Hinterrad ein Lenkrad.The rear wheel is also preferably a steering wheel.

Besonders in dieser Ausführungsweise ist das Fahrzeug sehr leicht lenkbar und kann es ziemlich eng wenden.In this embodiment in particular, the vehicle is very easy to steer and can turn quite closely.

Andere Kennzeichen und Vorteile der Erfindung treten deutlicher zutage aus der nachfolgenden Beschreibung eines erfindungsgemässen Fahrzeuges für den Transport eines Stapels loser Steine; diese ausschliesslich als Beispiel ohne irgendeine beschränkende Absicht gegebene Beschreibung findet anhand der beiliegenden Zeichnungen statt, wo die Abbildung 1 eine Seitenansicht eines erfindungsgemäßen Fahrzeuges für den Transport eines Stapels loser Steine darstellt; Die Abbildung 2 eine im Schnitt gezeichnete Vorderansicht des Fahrzeuges der Abbildung 1 ist; die Abbildung 3 einen Durchschnitt gemäß der Linie 111-111 der Abbildung 2, aber nur des Vorderteils des Fahrzeuges wiedergibt; die Abbildung 4 einen Durchschnitt des Vorderteils des Fahrzeuges analog dem der Abbildung 3, aber mit den Steinbehälter in einer anderen Position wiedergibt; und die Abbildung 5 eine Draufsicht des Vorderteils des Fahrzeuges der vorigen Abbildungen ist.Other characteristics and advantages of the invention emerge more clearly from the following description of a vehicle according to the invention for the transport of a stack of loose stones; this description, given by way of example only and without any restrictive intent, takes place with reference to the accompanying drawings, in which Figure 1 shows a side view of a vehicle according to the invention for the transport of a stack of loose stones; Figure 2 is a sectional front view of the vehicle of Figure 1; Figure 3 shows an average along line 111-111 of Figure 2 but only the front of the vehicle; Figure 4 shows an average of the front part of the vehicle analogous to that of Figure 3, but with the stone container in a different position; and Figure 5 is a top view of the front of the vehicle of the previous figures.

In den verschiedenen Abbildungen beziehen sich gleiche Bezugsnummern auf gleiche Elemente.In the different figures, the same reference numbers refer to the same elements te.

Das in der Abbildung 1 dargestellte Fahrzeug zum Transport eines Stapels loser Steine umfaßt ein Gestell 1, das von zwei starren Vorderrädern 2 und zwei hinteren Lenkrädern 3 getragen wird. Das Fahrzeug ist ein eigenangetriebenes Fahrzeug mit einem durch den obenliegenden Kraftstoffbehälter 5 gespeisten Kraftstoffmotor 4. Dieser Motor 4 treibt einen hydraulischen Kompressor 6 an. Dieser Kompressor 6 steht via einer Verteilklappe 7 einerseits über eine Leitung 8 mit einem Öltank 9 und andererseits über nicht in den Abbildungen dargestellte Leitungen mit zwei hydraulischen Motoren 10 und Zylinder-Kolbenmechanismen 11 und 12 in Verbindung, wie nachfolgend beschrieben wird.The vehicle shown in Figure 1 for transporting a stack of loose stones comprises a frame 1 which is supported by two rigid front wheels 2 and two rear steering wheels 3. The vehicle is a self-propelled vehicle with a fuel engine 4 fed by the overhead fuel tank 5. This engine 4 drives a hydraulic compressor 6. This compressor 6 is connected via a distribution flap 7 on the one hand via a line 8 to an oil tank 9 and on the other hand via lines not shown in the figures with two hydraulic motors 10 and cylinder-piston mechanisms 11 and 12, as will be described below.

Die Vorderräder 2 werden gesondert von einem der hydraulischen Motoren 10 angetrieben, die an Querträgern befestigt sind, welche ein Teil des Gestells 1 sind. Sie werden gesondert von dem auf dem Sitz 13 sitzenden Fahrer mittels zwei Hebel 14 gelenkt.The front wheels 2 are driven separately by one of the hydraulic motors 10, which are fastened to cross members, which are part of the frame 1. They are steered separately by the driver sitting on the seat 13 by means of two levers 14.

Wenn die beiden Motoren 10 mit derselben Geschwindigkeit laufen, fährt das Fahrzeug gerade aus. Durch Erhöhen der Geschwindigkeit eines der Motoren 10 kann man das Fahrzeug schwenken, auch dank der Tatsache, daß die Hinterräder Lenkräder 3 sind. Das Fahrzeug kann sehr eng und fast zur Stelle wenden, und zwar ohne eine bereits verlegte Pflasterung, worüber das Fahrzeug fährt, zu beschädigen.If the two motors 10 are running at the same speed, the vehicle is just extending. By increasing the speed of one of the motors 10, one can swivel the vehicle, also thanks to the fact that the rear wheels are steering wheels 3. The vehicle can turn very tightly and almost on the spot, and without damaging the pavement that the vehicle is driving over.

Vor den Vorderrädern 2 ist auf dem Gestell 1 ein Steinbehälter 15 schwenkbar montiert.In front of the front wheels 2, a stone container 15 is pivotally mounted on the frame 1.

Dieser Behälter 15 enthält eine sich von unten nach oben ausstreckende, fast flache Stütze, die aus einem aus Metallrohren hergestellten Rahmen 16 und einem darauf festgeschweißten Netz 17 besteht.This container 15 contains an almost flat support which extends from bottom to top and consists of a frame 16 made of metal pipes and a mesh 17 welded thereon.

Die Unterseite des Rahmens bildet sich aus einem horizontalen, hohlen Quadratrohr 18, das sich in die Querrichtung des Fahrzeuges ausstreckt. In beiden offenen Enden dieses Rohrs 18 ist ein quadratisches Tragrohr 19 verschiebbar, das an seinem Ende einen Arm 20 trägt.The underside of the frame forms a horizontal, hollow square tube 18 which extends in the transverse direction of the vehicle. In both open ends of this tube 18, a square support tube 19 is displaceable, which carries an arm 20 at its end.

Die zwei Arme 20 auf den zwei Tragrohren 19 strecken sich beiderseits der Stütze 16,17 nach vorne, praktisch senkrecht zur Ebene der Stütze 16,17 aus.The two arms 20 on the two support tubes 19 extend forward on both sides of the support 16, 17, practically perpendicular to the plane of the support 16, 17.

Die zwei Arme 20 sind an deren einander zugewandten Seiten mit zwei um eine Vertikalachse gelenkig montierten Füßchen 21 versehen, welche mit zwei Reihen Steinen übereinstimmen.The two arms 20 are provided on their mutually facing sides with two feet 21 articulated about a vertical axis, which match two rows of stones.

In der Abbildung 5 sind diese Steine in Strickpunktlinie gezeichnet und mit der Bezugszahl 22 angegeben. Indem die Füßchen 21 gelenkig sind, wird der von den zwei Armen 20 auf die Reihen Steine 22 ausgeübte Druck gleichmäßig über die zwei Reihen verteilt, auch wenn die Reihenlängen nicht genau gleich sind.In Figure 5, these stones are drawn in a knitting line and given the reference number 22. Because the feet 21 are articulated, the pressure exerted by the two arms 20 on the rows of stones 22 is distributed evenly over the two rows, even if the row lengths are not exactly the same.

Die zwei Arme 20 können nach hinten und auseinander geschoben werden mittels der zwei Zylinder-Kolbenmechanismen 11, deren Zylinder oben auf dem Rohr 18 befestigt sind und deren Kolben mit an der Rückseite der Stütze 16,17 ausragenden Enden der jeweiligen zwei Arme 20 verbunden sind.The two arms 20 can be pushed backwards and apart by means of the two cylinder piston mechanisms 11, the cylinders of which are fastened on the top of the tube 18 and the pistons of which are connected to the ends of the respective two arms 20 projecting from the rear of the support 16, 17.

Die zwei Zylinder-Kohlenmechanismen werden natürlich zusammen betätigt, so daß also die zwei Arme 20 zugleich zueinander oder auseinander geschoben werden.The two cylinder-carbon mechanisms are of course actuated together, so that the two arms 20 are pushed towards one another or apart at the same time.

An der Rückseite des Rahmens 16 der Stütze 16,17 sind zwei Sätze von je drei Stangen 23 festgeschweißt. Diese Stangen erstrecken sich rückwärts zueinander und sind mit ihren zusammenlaufenden Enden um eine horizontale Scharnierachse 24 auf einem unteren Querprofilrahmen befestigt, der sich vorne am Gestell 1 quer zwischen den zwei Rädern 2 erstreckt.On the back of the frame 16 of the support 16, 17 two sets of three rods 23 are welded. These rods extend backwards to one another and are fastened with their converging ends about a horizontal hinge axis 24 on a lower transverse profile frame which extends transversely between the two wheels 2 at the front of the frame 1.

Das Drehen der Stütze 16,17 und somit des vollständigen Behälters 15 wird durch den Zylinder-Kolbenmechanismus 12 ausgelöst, dessen Zylinder gerade hinter der Stütze 16,17 um die Horizontalachse 25 gelenkig befestigt ist an zwei nach vorne hinausstreckenden horizontalen Armen 26, die an dem oberen Profilrahmen der zwei Profilrahmen geschweißt sind, welche sich vorne am Gestell 1 zwischen den zwei Rädern 2 erstrecken. Der Kolben ist gelenkig befestigt an zwei kleinen Armen 27, die auf der Rückseite des Hohlrohrs 18 geschweißt sind.The rotation of the support 16, 17 and thus of the complete container 15 is triggered by the cylinder-piston mechanism 12, the cylinder of which is articulated just behind the support 16, 17 about the horizontal axis 25 on two forward-extending horizontal arms 26, which on the upper profile frame of the two profile frames are welded, which extend at the front of the frame 1 between the two wheels 2. The piston is articulated to two small arms 27 which are welded to the back of the hollow tube 18.

In dieser Weise kann der Behälter 5 zwischen dem in den Abbildungen 1-3 dargestellten Stand und dem in der Abbildung 4 dargestellten Stand drehen.In this way, the container 5 can rotate between the level shown in Figures 1-3 and the level shown in Figure 4.

Um einen kleinen Stapel Steine 22 von einem größeren Stapel abzunehmen und zu transportieren, fährt man das obenbeschriebene Fahrzeug, bis sich zwei äußerste gestapelte Reihen des großen Stapels zwischen den Armen 20 befinden.In order to remove and transport a small stack of stones 22 from a larger stack, one drives the vehicle described above until there are two outermost stacked rows of the large stack between the arms 20.

Man dreht den Behälter 15 bis in den in den Abildungen 1-3 dargestellten Stand hinunter, in dem sich also die Arme 20 gerade über dem Boden befinden.The container 15 is rotated down to the position shown in FIGS. 1-3, in which the arms 20 are located just above the floor.

Mit Hilfe des Zylinder-Kolbenmechanismus 11 bringt man die Arme 20 zueinander, wobei also die zwei unteren Reihen Steine 22 des wegzunehmenden Stäpelchens zwischen diesen Armen 20 eingeklemmt werden. Man kippt dann mit Hilfe des Zylinder-Kolbenmechanismus 12 den Behälter 15 bis in den in Abbildung 4 dargestellten Stand, wodurch also das letztgenannte Stäpelchen vom Boden aufgehoben wird und wobei die Reihen Steine, die sich über den eingeklemmten unteren Reihen Steine 22 befinden, gegen die Stütze 16,17 ruhen.With the help of the cylinder-piston mechanism 11, the arms 20 are brought together, so that the two lower rows of stones 22 of the stack to be removed are clamped between these arms 20. The container 15 is then tilted with the aid of the cylinder-piston mechanism 12 to the position shown in FIG. 4, which means that the last-mentioned stack is lifted from the floor and the rows of stones that are located above the clamped lower rows of stones 22 against the Rest column 16, 17.

Man kann nun das Stäpelchen bis zur gewünschten Stelle transportieren.You can now transport the stack to the desired location.

Die Konstruktion und die Bedienung des Fahrzeuges sind verhältnismäßig einfach.The construction and operation of the vehicle are relatively simple.

Das Fahrzeug ist relativ kompakt und läßt sich sehr lenken.The vehicle is relatively compact and can be steered very easily.

Es können also kleinere Stäpelchen sehr schnell einem größeren Stapel loser Steine entnommen und transportiert werden.Smaller stacks can therefore be removed and transported very quickly from a larger stack of loose stones.

Die Erfindung beschränkt sich keineswegs auf die obenbeschriebene Ausführungsweise, die innerhalb des Erfindungsrahmens auf vielerlei Weisen abgeändert werden kann, u.a. was die Form, die Zusammenstellung, die Anordnung und die Zahl der Einzelteile betrifft, die zur Realisierung der Erfindung verwendet werden.The invention is in no way limited to the embodiment described above, which can be modified in many ways within the scope of the invention, i.a. as regards the shape, the composition, the arrangement and the number of individual parts which are used to implement the invention.
