Definitions
- the invention relates to a stone laying machine according to the preamble of claim 1.
- Such a stone laying machine is known in which a laying tongs, for example for paving stones or the like, are attached to an extension arm which can be controlled from the driver's cab of the laying machine.
- the front wheels can be rotated about a pivot point which is located on the longitudinal center line of the laying machine behind the front axle.
- the rear wheels can be rotated about a pivot point which is located on the longitudinal center line in front of the rear axle.
- the front axles and the rear axles holding parts are pivotally articulated to an elongated spacer at the mentioned pivot points.
- the main structure such as the internal combustion engine, the drive hydraulics, the driver's seat and the cantilever arm are attached to the holding part holding the front axle in this laying machine.
- a problem of such a laying machine can occur when the front and rear axles are pivoted with respect to one another during a laying operation while driving, so that the center of gravity of the laying machine lies outside the imaginary line which is the center of the longitudinal extension of the front and rear axles with one another connects. It can then happen that the entire laying machine tips over. To rule out this case, the aforementioned extreme position of the front axle with respect to the rear axle in the known laying machine must be avoided while driving. However, this reduces the operating radius of the laying machine.
- the object of the present invention is therefore to provide a stone laying machine in which the entire fastening structure for the delivery can be carried out relatively easily and light-weight.
- a major advantage of the present stone laying machine is that it has a comparatively large radius of action or is very manoeuvrable. This can make laying work much easier. In addition, it is achieved that the stone laying machine according to the invention can be used more universally than comparable, known laying machines.
- Another advantage of the invention is that the center of gravity of the laying machine is very low due to the new construction of the chassis with sufficient ground clearance, which leads to a further increase in stability.
- the laying machine according to the invention is advantageously particularly easy to control.
- the front and rear wheels are automatically steered in opposite directions using only one steering cylinder, which leads to the particularly great maneuverability and therefore to the good operating radius.
- the present laying machine has great maneuverability because the extension arm follows the rotation of the front axle.
- the stone laying machine according to the invention is of relatively simple construction and can therefore also be produced economically.
- the idea was arranged to arrange the cantilever arm in such a way that it follows the steering movement of the front wheels, and the abovementioned structures and installations of the laying machine not on the holding part for the front axle, but on the holding parts for the front and Fasten the base frame connecting the rear axle. Since the boom arm should follow the movement of the front axle, the entire load torque would have to be supported solely via the front pivot point. For this reason, especially in this area, the construction would have to be particularly strong, but this would mean that the center of gravity of the laying machine would undesirably move forward and that the driver would lose sight of the laying edge due to the reinforced construction.
- the cantilever arm is therefore not only fastened in the area of the front axle but also on a physical axis which runs perpendicular to the front pivot point, is rigidly connected to the front axle and above the front pivot point in a further pivot point, which is preferably located in the roof structure of the laying machine, is rotatably held.
- This ensures that the entire mounting structure for the cantilever arm can be made relatively simple and lightweight, since the forces exerted by the cantilever arm not only act on the front axle, but are also distributed over the area of the roof structure of the laying machine.
- the present stone laying machine is designated 1. It essentially has front wheels 2, rear wheels 3, a front axle 4 connecting the front wheels, a rear axle 5 connecting the rear wheels, one Base frame 6, on which the front axle 4 and the rear axle 5 can be steered by a steering device which will be explained in more detail later, a structure attached to the base frame 6 with a roof structure 7 and a cantilever arm 8, which can be controlled from the driver's station of the laying machine 1 and on whose free end is a known laying device 9, for example laying pliers, can be fastened.

- the axis 10 running perpendicular to the pivot point 11 is rigidly connected to the fastening device 12 so that it follows the movement of the front axis 4.
- Preferably has the base frame 6 of the body axis 10 side facing obliquely in the direction of the front axle 4 end portion 10 ', which is fixedly connected to the rotatable holding the front axle 4 area.
- the opposite end of the physical axis 10 is rotatably connected above the front pivot point 11 in a part connected to the base frame 6 or the vehicle body.
- said end of the body axis 10 is rotatably mounted in a region of the roof structure 7 of the laying machine 12.
- the cantilever arm 8 is preferably actuated by a lifting cylinder 13 which can be controlled from the vehicle position, one end of which is connected to the cantilever arm 8 and the other end of which is connected to the laying machine 1, preferably to the end region 10 'which extends from the physical axis 10 to the front axis 4 .

- the rear axle 5 is preferably secured with the aid of a fastening device 15, which likewise has the shape of a plate, one side of which is attached to an area that rotatably holds the rear axle 5, and the pivot point 14 is arranged in the area of the other side of the plate.
- the steering is preferably carried out by a steering cylinder 16 which is fastened on the one hand to the base frame 6 and on the other hand expediently to the fastening device 12 holding the front axle 4.

Description
Die Erfindung betrifft eine Stein-Verlegemaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a stone laying machine according to the preamble of claim 1.
Es ist eine derartige Stein-Verlegemaschine bekannt, bei der an einem Auslegerarm, der vom Führerstand der Verlegemaschine aus steuerbar ist, eine Verlegezange z.B. für Pflastersteine oder dergleichen befestigt ist. Bei dieser bekannten Verlegemaschine sind die Vorderräder um einen Drehpunkt drehbar, der sich auf der Längsmittellinie der Verlegemaschine hinter der Vorderachse befindet. In der entsprechenden Weise sind die Hinterräder um einen Drehpunkt drehbar, der sich auf der genannten Längsmittellinie vor der Hinterachse befindet. Dabei sind jeweils die Vorderachse bzw. die Hinterachse haltende Halteteile in den genannten Drehpunkten an ein längliches Abstandsteil verschwenkbar angelenkt. Der hauptsächliche Aufbau, wie z.B. der Verbrennungsmotor, die Antriebshydraulik, der Fahrersitz sowie der Auslegerarm sind bei dieser Verlegemaschine an dem die Vorderachse haltendem Halteteil befestigt. Ein Problem einer derartigen Verlegemaschine kann dann eintreten, wenn bei einer Verlegeoperation während der Fahrt die Vorder- und Hinterachse in bezug aufeinander so verschwenkt werden, daß der Schwerpunkt der Verlegemaschine außerhalb der gedachten Linie liegt, die die Mittelpunkte der Längserstreckung der Vorder- und Hinterachse miteinander verbindet. Es kann dann der Fall eintreten, daß die gesamte Verlegemaschine kippt. Um diesen Fall auszuschließen, muß die zuvor genannte extreme Stellung der Vorderachse zur Hinterachse bei der bekannten Verlegemaschine während der Fahrt vermieden werden. Dadurch wird aber der Aktionsradius der Verlegemaschine verkleinert.Such a stone laying machine is known in which a laying tongs, for example for paving stones or the like, are attached to an extension arm which can be controlled from the driver's cab of the laying machine. In this known laying machine, the front wheels can be rotated about a pivot point which is located on the longitudinal center line of the laying machine behind the front axle. In a corresponding manner, the rear wheels can be rotated about a pivot point which is located on the longitudinal center line in front of the rear axle. The front axles and the rear axles holding parts are pivotally articulated to an elongated spacer at the mentioned pivot points. The main structure, such as the internal combustion engine, the drive hydraulics, the driver's seat and the cantilever arm are attached to the holding part holding the front axle in this laying machine. A problem of such a laying machine can occur when the front and rear axles are pivoted with respect to one another during a laying operation while driving, so that the center of gravity of the laying machine lies outside the imaginary line which is the center of the longitudinal extension of the front and rear axles with one another connects. It can then happen that the entire laying machine tips over. To rule out this case, the aforementioned extreme position of the front axle with respect to the rear axle in the known laying machine must be avoided while driving. However, this reduces the operating radius of the laying machine.
Aus Baumaschine + Bautechnik. BMT 31 (1984) Juni/Juli, No. 6/7, S 241-248 geht eine Steinverlegemaschine hervor, bei der der Auslegerarm an der Dachkonstruktion befestigt und zusammen mit dieser um eine horizontale Drehachse verschwenkbar ist, die sich hinter dem Fahrer befindet.From construction machine + construction technology. BMT 31 (1984) June / July, No. 6/7, S 241-248 shows a stone laying machine in which the cantilever arm is attached to the roof structure and can be pivoted together with it about a horizontal axis of rotation, which is located behind the driver.
Aus der AU-B-549 903 geht eine Steinverlegemaschine der eingangs genannten Art hervor, bei der der Auslegerarm an zwei vertikalen Streben befestigt ist, deren untere Enden an die Bewegung der Vorderachse gekoppelt sind. Die Befestigungskonstruktion für die Streben muß relativ solide und aufwendig gehalten sein.From AU-B-549 903 emerges a stone laying machine of the type mentioned in the introduction, in which the extension arm is attached to two vertical struts, the lower ends of which are coupled to the movement of the front axle. The mounting structure for the struts must be kept relatively solid and expensive.
Die Aufgabe der vorliegenden Erfindung besteht daher darin, eine Stein-Verlegemaschine zu schaffen, bei der die gesamte Befestigungskonstruktion für den Auslager relativ einfach und kleingewichtig ausgeführt werden kann.The object of the present invention is therefore to provide a stone laying machine in which the entire fastening structure for the delivery can be carried out relatively easily and light-weight.
Diese Aufgabe wird durch eine Stein-Verlegemaschine der eingangs genannten Art gelöst, die durch die in dem kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gekennzeichnet ist.This object is achieved by a stone laying machine of the type mentioned, which is characterized by the features specified in the characterizing part of patent claim 1.
Ein wesentlicher Vorteil der vorliegenden Stein-Verlegemaschine besteht darin, daß sie einen vergleichsweise großen Aktionsradius aufweist bzw. sehr wendig ist. Dadurch können die Verlegearbeiten wesentlich erleichtert.werden. Außerdem wird erreicht, daß die erfindungsgemäße Stein-Verlegemaschine universeller einsetzbar ist, als vergleichbare, bekannte Verlegemaschinen.A major advantage of the present stone laying machine is that it has a comparatively large radius of action or is very manoeuvrable. This can make laying work much easier. In addition, it is achieved that the stone laying machine according to the invention can be used more universally than comparable, known laying machines.
Ein weiterer Vorteil der Erfindung besteht darin, daß der Schwerpunkt der Verlegemaschine aufgrund der neuen Konstruktion des Fahrwerkes bei ausreichender Bodenfreiheit sehr tief liegt, was zu einer weiteren Vergrößerung der Standsicherheit führt.Another advantage of the invention is that the center of gravity of the laying machine is very low due to the new construction of the chassis with sufficient ground clearance, which leads to a further increase in stability.
Bedingt durch diese neuartige Konstruktion kann der Fahrersitz tiefliegend angeordnet werden, was ein bequemes Ein- und Aussteigen ermöglicht. Vorteilhafterweise ist die erfindungsgemäße Verlegemaschine besonders einfach steuerbar. Vorteilhafterweise werden bei der erfindungsgemäßen Verlegemaschine die Vorder- und Hinterräder unter Anwendung nur eines Lenkzylinders automatisch in entgegengesetzte Richtungen gelenkt, was zu der besonders großen Wendigkeit und daher zu dem guten Aktionsradius führt. Bei der erfindungsgemäßen Stein-Verlegemaschine ist dabei vorteilhafterweise immer sichergestellt, daß der Schwerpunkt der Verlegemaschine nicht so weit aus dem Bereich der die Mittelpunkte der Längserstreckung der Achsen verbindenden Linie gelangt, daß ein schädliches und gefährliches Kippmoment auftreten kann.Due to this new construction, the driver's seat can be arranged low, which makes it easy to get on and off. The laying machine according to the invention is advantageously particularly easy to control. Advantageously, in the laying machine according to the invention, the front and rear wheels are automatically steered in opposite directions using only one steering cylinder, which leads to the particularly great maneuverability and therefore to the good operating radius. In the stone laying machine according to the invention, it is advantageously always ensured that the center of gravity of the laying machine does not come so far from the area of the line connecting the centers of the longitudinal extension of the axes that a harmful and dangerous tilting moment can occur.
Die Wendigkeit ist bei der vorliegenden Verlegemaschine groß, weil der Auslegerarm der Drehung der Vorderachse folgt.The present laying machine has great maneuverability because the extension arm follows the rotation of the front axle.
Vorteilhafterweise ist die erfindungsgemäße Stein-Verlegemaschine relativ einfach aufgebaut und daher auch kostengünstig herstellbar.Advantageously, the stone laying machine according to the invention is of relatively simple construction and can therefore also be produced economically.
Im folgenden werden die Erfindung und deren Ausgestaltungen im Zusammenhang mit den Figuren näher erläutert. Es zeigt:
- Fig. 1 in perspektivischer Darstellung eine Seitenansicht der vorliegenden Stein-Verlegemaschine, und
- Fig. 2 eine Aufsicht der Verlegemaschine der Fig. 1 zur Erläuterung der Lenkeinrichtung.
- Fig. 1 is a perspective view of a side view of the present stone laying machine, and
- Fig. 2 is a plan view of the laying machine of Fig. 1 to explain the steering device.
Zu der Erfindung führten die folgenden Überlegungen:
Um im Vergleich zu den bekannten Verlegemaschinen eine erhöhte Kippsicherheit während der Fahrt bei einem möglichst kleinen Wenderadius zu erreichen, wurde der Gedanke gefaßt, den Auslegerarm so anzuordnen, daß er der Lenkbewegung der Vorderräder folgt, und die zuvor genannten Auf- bzw. Einbauten der Verlegemaschine nicht am Halteteil für die Vorderachse, sondern an dem die Halteteile für die Vorder- und Hinterachse verbindenden Grundrahmen zu befestigen. Da der Auslegerarm der Bewegung der Vorderachse folgen soll, müßte das gesamte Lastmoment allein über den vorderen Drehpunkt abgestützt werden. Aus diesem Grunde müßte insbesondere in diesem Bereich die Konstruktion besonders stark ausgeführt werden, was aber dazu führt, daß der Schwerpunkt der Verlegemaschine unerwünscht nach vorne veilagert würde und daß dem Fahrer aufgrund der verstärkten Konstruktion die Sicht auf die Verlegekante genommen würde.The following considerations led to the invention:
In order to achieve increased safety against tipping while driving with the smallest possible turning radius compared to the known laying machines, the idea was arranged to arrange the cantilever arm in such a way that it follows the steering movement of the front wheels, and the abovementioned structures and installations of the laying machine not on the holding part for the front axle, but on the holding parts for the front and Fasten the base frame connecting the rear axle. Since the boom arm should follow the movement of the front axle, the entire load torque would have to be supported solely via the front pivot point. For this reason, especially in this area, the construction would have to be particularly strong, but this would mean that the center of gravity of the laying machine would undesirably move forward and that the driver would lose sight of the laying edge due to the reinforced construction.
Zur Verhinderung der vorgenannten Probleme wird bei der vorliegenden Erfindung der Auslegerarm daher nicht nur im Bereich der Vorderachse, sondern an einer körperlichen Achse befestigt, die senkrecht zum vorderen Drehpunkt verläuft, starr mit der Vorderachse verbunden ist und oberhalb des vorderen Drehpunktes in einem weiteren Drehpunkt, der sich vorzugsweise in der Dachkonstruktion der Verlegemaschine befindet, drehbar gehalten wird. Dadurch wird erreicht, daß die gesamte Befestigungskonstruktion für den Auslegerarm relativ einfach und kleingewichtig ausgeführt werden kann, da die von dem Auslegerarm ausgeübten Kräfte nicht ausschließlich an der Vorderachse angreifen, sondern auch auf den Bereich der Dachkonstruktion der Verlegemaschine verteilt werden.In order to prevent the aforementioned problems, the cantilever arm is therefore not only fastened in the area of the front axle but also on a physical axis which runs perpendicular to the front pivot point, is rigidly connected to the front axle and above the front pivot point in a further pivot point, which is preferably located in the roof structure of the laying machine, is rotatably held. This ensures that the entire mounting structure for the cantilever arm can be made relatively simple and lightweight, since the forces exerted by the cantilever arm not only act on the front axle, but are also distributed over the area of the roof structure of the laying machine.
In der Fig. 1 ist die vorliegende Stein-Verlegemaschine mit 1 bezeichnet. Sie weist im wesentlichen Vorderräder 2, Hinterräder 3, eine die Vorderräder verbindende Vorderachse 4, eine die Hinterräder verbindende Hinterachse 5, einen Grundrahmen 6, an dem die Vorderachse 4 und die Hinterachse 5 durch eine später noch näher erläuterte Lenkeinrichtung lenkbar gehalten werden,einen am Grundrahmen 6 angebrachten Aufbau mit einer Dachkonstruktion 7 und einen Auslegerarm 8 auf, der vom Fahrerstand der Verlegemaschine 1 aus steuerbar ist und an dessem freien Ende eine an sich bekannte Verlege einrichtung 9 z.B. eine Verlegezange, befestigbar ist. Die Verlegemaschine 1 ist mit einem nicht näher dargestellten Antriebsmotor, der insbesondere die Form eines Elektro- oder Dieselmotors aufweist, ausgerüstet.In Fig. 1, the present stone laying machine is designated 1. It essentially has
Der Auslegerarm 8, der vorzugsweise die Form eines sich nach unten öffnenden Winkels aufweist, ist mit seinem einen freien Ende in der vertikalen Ebene um den Drehpunkt 30 verschwenkbar an einer körperlichen Achse 10 befestigt, die senkrecht zu dem Drehpunkt 11 verläuft, um den die Vorderachse 4 am Grundrahmen 6 verschwenkbar ist. Vorzugsweise befindet sich der Drehpunkt 11 hinter der Vorderachse 4 auf der Längsmittellinie der Verlegemaschine 1, wobei sein Abstand zur Vorderachse a ist. Zu diesem Zweck wird die Vorderachse 4 vorzugsweise in einer Befestigungseinrichtung 12 gehalten, die vorzugsweise die Form einer Platte aufweist, wobei die eine Seite der Platte an einem die Vorderachse 4 drehbar haltenden Bereich befestigt ist und wobei sich der Drehpunkt 11 im Bereich der anderen Seite der Platte befindet. Die senkrecht zum Drehpunkt 11 verlaufende Achse 10 ist starr mit der Befestigungseinrichtung 12 verbunden, so daß sie der Bewegung der Vorderachse 4 folgt. Vorzugsweise weist die dem Grundrahmen 6 der körperlichen Achse 10 zugewandte Seite einen schräg in Richtung auf die Vorderachse 4 verlaufenden Endbereich 10′ auf, der fest mit dem die Vorderachse 4 drehbar haltenden Bereich verbunden ist. Das gegenüberliegende Ende der körperlichen Achse 10 ist oberhalb des vorderen Drehpunktes 11 drehbar in einem mit dem Grundrahmen 6 bzw. dem Fahrzeugaufbau verbundenen Teil verbunden. Insbesondere ist das genannte Ende der körperlichen Achse 10 drehbar in einem Bereich der Dachkonstruktion 7 der Verlegemaschine 12 gelagert.The cantilever arm 8, which preferably has the shape of a downward opening angle, is fastened with its one free end in the vertical plane about the fulcrum 30 to a
Der Auslegerarm 8 wird vorzugsweise durch einen vom Fahrzeugstand aus steuerbaren Hubzylinder 13 betätigt, dessen eines Ende mit dem Auslegerarm 8 und dessen anderes Ende mit der Verlegemaschine 1, vorzugsweise mit dem sich von der körperlichen Achse 10 aus zur Vorderachse 4 erstreckenden Endbereich 10′ verbunden ist.The cantilever arm 8 is preferably actuated by a lifting
In der aus der Fig. 2 ersichtlichen Weise ist die Hinterachse 5 ähnlich wie die Vorderachse 4 an dem Grundrahmen 6 drehbar gelagert, wobei sich der hintere Drehpunkt 14 ebenfalls auf der Längsmittellinie der Verlegemaschine 1 und vor der Hinterachse 3 befindet, und wobei sein Abstand zur Hinterachse b ist. Vorzugsweise ist die Hinterachse 5 mit der Hilfe einer Befestigungseinrichtung 15, die ebenfalls die Form einer Platte aufweist, deren eine Seite an einem die Hinterachse 5 drehbar haltenden Bereich befestigt ist und wobei der Drehpunkt 14 im Bereich der anderen Seite der Platte angeordnet ist, befestigt. Die Lenkung erfolgt vorzugsweise durch einen Lenkzylinder 16, der einerseits am Grundrahmen 6 und andererseits zweckmäßigerweise an der die Vorderachse 4 haltenden Befestigungseinrichtung 12 befestigt ist. Der Lenkzylinder 16 wird vom Fahrstand aus gesteuert. Um eine Kopplung zwischen der Lenkbewegung der Hinterachse 5 und der Lenkbewegung der Vorderachse 4 zu erreichen, ist vorzugsweise eine Koppelstange 17 vorgesehen, deren eines Ende an die vordere Befestigungseinrichtung 12 und deren anderes Ende an die hintere Befestigungseinrichtung 15 so angelenkt sind, daß die Vorder- und Hinterräder 4,5 gegensinnig gelenkt werden. Insbesondere sind die Enden der Koppelstange 17 an Seitenflächen der Befestigungseinrichtungen 12,15 angelenkt, die in bezug auf die Lenkmittelachse der Verlegemaschine 1 sich gegenüberliegen.In the manner shown in FIG. 2, the rear axle 5 is rotatably mounted on the base frame 6, similar to the
An der Stelle der genannten Koppelstange können auch zwei Lenkzylinder vorgesehen werden, die gegenphasig gesteuert werden und von denen jeweils einer zwischen einer Befestigungseinrichtung 12, bzw. 15 und dem Grundrahmen 6 wirksam ist. Der bzw. die genannten Lenkzylinder können auch durch sogenannte Lenkgetriebe ersetzt werden.In place of the coupling rod mentioned, two steering cylinders can also be provided, which are controlled in opposite phase and one of which is effective between a
Wenn beispielsweise die Vorderachse 4 so gelenkt wird, daß im vorderen Drehpunkt 11 eine Drehung im Uhrzeigersinn erfolgt (Pfeil 18), wird die Koppelstange 17 in der Richtung des Pfeiles 19 verschoben, was zur Folge hat, daß die Hinterachse 5 um den Drehpunkt 14 entgegen dem Uhrzeigersinn gedreht wird (Pfeil 20).For example, if the
Durch eine gezielte Variation der Strecken a und b können der Lenkeinschlag und damit der Wendekreis und die Standsicherheit auch zur Anpassung der Verlegemaschine an unterschiedliche Anwendungsfälle optimiert werden, ohne daß dadurch eine wesentliche Umkonstruktion erforderlich ist.By specifically varying the distances a and b, the steering angle and thus the turning circle and the stability can also be optimized for adapting the laying machine to different applications, without this necessitating a major redesign.
Von wesentlicher Bedeutung ist, daß der Grundrahmen 6, der den Aufbau und die wesentlichen Einbauten der Verlegemaschine 1 trägt, so angeordnet ist, daß er die Drehpunkte 11, 14 für die Befestigungseinrichtung 12, 15 für Vorder- und Hinterachse 4, 5 aufweist und daß gleichzeitig der Auslegerarm 8 an einer sich senkrecht zum vorderen Drehpunkt 11 erstreckenden körperlichen Achse 10 befestigt ist, deren eines Ende an der vorderen Befestigungseinrichtung 12 starr befestigt und deren anderes Ende an dem Aufbau des Grundrahmens 6, vorzugsweise an einer Dachkonstruktion 7, drehbar befestigt sind. Dabei ist es von besonderer Bedeutung, daß der Schwerpunkt des Grundrahmens 6 und der an ihm angeordneten Ein- und Aufbauten bei der vorliegenden Verlegemaschine 1 nur wenig oberhalb der Ebene der Vorder- und Hinterachse 4,5 liegen kann.It is essential that the base frame 6, which carries the structure and the essential internals of the laying machine 1, is arranged so that it has the pivot points 11, 14 for the
Es ist auch denkbar, den Auslegerarm 8 so zu gestalten, daß er mit oder ohne einer gleichzeitigen Verschwenkbewegung entlang der körperlichen Achse 10 heb- und absenkbar ist.It is also conceivable to design the cantilever arm 8 in such a way that it can be moved with or without a simultaneous pivoting movement the
