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 dergl. 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, is 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 are rotatable 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 one Construction, 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 arise if, during a laying operation, the front and rear axles are pivoted in relation to one another in such a way that the center of gravity of the laying machine lies outside the imaginary line which is the center of the longitudinal extent 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 relative to the rear axle in the known laying machine must be avoided while driving. However, this reduces the operating radius of the laying machine.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, eine Stein-Verlegemaschine der eingangs genannten Art dahin­gehend zu verbessern, daß ihr Aktionsradius vergrößert wird, ohne daß die Gefahr eines Kippens der Verlegemaschine besteht.The object of the present invention is therefore to improve a stone laying machine of the type mentioned in such a way that its radius of action is increased without the risk of the laying machine tipping over.

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 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 is not so far from the area of the center of the longitudinal extent. the line connecting the axles that a harmful and dangerous overturning 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 inexpensively.

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.
The invention and its configurations are explained in more detail below in connection with the figures. It shows:
  • 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:The following considerations led to the invention:

Um im Vergleich zu den bekannten Verlegemaschinen eine erhöhte Kippsicherheit während der Fahrt bei einem möglichst kleinen Wenderadius zu erreichen, wurde erstmals 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 verlagert würde und daß dem Fahrer aufgrund der verstärkten Konstruktion die Sicht auf die Verlegekante genommen würde.In order to achieve an increased tipping safety while driving with the smallest possible turning radius compared to the known laying machines, the first thought was to arrange the cantilever arm in such a way that it follows the steering movement of the front wheels, and the aforementioned structures and fittings 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 be undesirably shifted 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 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 region of the front axle, but rather on an axis which is perpendicular to the front pivot point, is rigidly connected to the front axle and above the front pivot point in a further pivot point, the 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 Ver­legezange 9 oder dergl. befestigbar ist.

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 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 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 Achse 10 drehbar in einem Bereich der Dachkon­struktion 7 der Verlegemaschine 12gelagert.The cantilever arm 8, which preferably has the shape of a downwardly opening angle, is fastened with its one free end in the vertical plane so as to be pivotable about the pivot point 30 on an axis 10 which is perpendicular to the pivot point 11 about which the front axis 4 is pivotable on the base frame 6. The pivot point 11 is preferably located behind the front axle 4 on the longitudinal center line of the laying machine 1, its distance from the front axle being a. For this purpose, the front axle 4 is preferably held in a holding part 12 which preferably has the shape of a plate, the one side of the plate being fastened to an area which rotatably holds the front axle 4 and the fulcrum 11 being located in the area of the other side of the Plate is located.

Preferably has the base frame 6 of the axis 10 side facing an 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 axle 10 is rotatably connected above the front pivot point 11 in a part connected to the base frame 6 or the vehicle body. In particular, said end of the axis 10 is rotatably mounted in a region of the roof structure 7 of the laying machine 12.

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 Stange 10 aus zur Vorderachse 4 erstreckenden Endbereich 10′ verbunden ist.The cantilever arm 8 is preferably actuated by a lifting cylinder 13 which can be controlled from the vehicle stand, 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 rod 10 to the front axle 4.

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 Befesti­gungseinrichtung 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 front axle 4, the rear pivot point 14 also being located on the longitudinal center line of the laying machine 1 and in front of the rear axle 3, and its distance from the Rear axle b is.

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. The steering cylinder 16 is controlled from the control station. In order to achieve a coupling between the steering movement of the rear axle 5 and the steering movement of the front axle 4, a coupling rod 17 is preferably provided, one end of which is articulated to the front fastening device 12 and the other end of which is articulated to the rear fastening device 15 such that the front and rear wheels 4.5 are steered in opposite directions. In particular, the ends of the coupling rod 17 are articulated on side surfaces of the fastening device 12, 15, which lie opposite one another with respect to the steering center axis of the laying machine 1.

An der Stelle der genannten Koppelstange können auch zwei Lenkzylinder vorgesehen werden, die gegenphasig gesteuert werden und von denen jeweils einer zwischen ein Halteteil 12, 15 und dem Grundrahmen wirksam ist. Der bzw. die genannten Lenkzylinder können auch durch sogenannte Lenkgetriebe er­setzt werden.At the location 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 holding part 12, 15 and the base frame. The steering cylinder or cylinders mentioned can also be replaced by so-called steering gears.

Wenn beispielsweise die Vorderachse 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 front axle is steered so that there is a clockwise rotation in the front pivot point 11 (arrow 18), the coupling rod 17 becomes in the direction the arrow 19 shifted, which has the consequence that the rear axle 5 is rotated counterclockwise about the pivot point 14 (arrow 20).

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.The steering angle and thus the turning circle and stability can also be optimized by adapting the distances a and b to adapt 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 Halteteile 12, 15 für die Vorder- und Hinterachse 4, 5 aufweist und daß gleichzeitig der Auslegerarm 8 an einer sich senkrecht zum vorderen Drehpunkt 11 erstreckenden Achse 10 befestigt ist, deren eines Ende an dem vorderen Halteteil 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 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 holding parts 12, 15 for the front and rear axles 4, 5 and that at the same time the cantilever arm 8 is fastened to an axis 10 extending perpendicular to the front pivot point 11, one end of which is rigidly fastened to the front holding part 12 and the other end of which is rotatably fastened to the structure of the base frame 6, preferably to a roof structure 7. It is particularly important that the center of gravity of the base frame 6 and the fittings and superstructures arranged on it in the present laying machine can only be slightly above the level of the front and rear axles 4, 5.

Es ist auch denkbar, den Auslegerarm 8 so zu gestalten, daß er mit oder ohne einer gleichzeitigen Verschwenkbewegung ent­ lang der Achse 10 heb- und absenkbar ist.It is also conceivable to design the cantilever arm 8 so that it ent with or without a simultaneous pivoting movement along the axis 10 can be raised and lowered.
