Description
Die Erfindung betrifft eine Autobetonpumpe mit einem als Lastkraftwagenchassis ausgebildeten Fahrgestell, mit einem im vorderen Bereich des Fahrgestells angeordneten Lagerbock, mit einem am Lagerbock um eine vertikale Achse drehbar und um eine horizontale Achse schwenkbar angeordneten, aus mehreren um horizontale Achsen gegeneinander begrenzt verschwenkbaren Mastarmen bestehenden, im zusammengeklappten Zustand auf mindestens einer, vorzugsweise als Mastauflagebock ausgebildeten Stützstelle im rückwärtigen Bereich des Fahrgestells abstützbaren Verteilermast, mit einem in der Nähe des rückwärtigen Endes des Fahrgestells angeordneten, eine nach oben weisende Einfüllöffnung aufweisenden Materialaufgabebehälter, mit einer saugseitig im Bereich einer pumpenseitigen Begrenzungswand an den Materialaufgabebehälter angeschlossenen und druckseitig mit einer sich über den Verteilermast erstreckenden Förderleitung verbundenen Betonpumpe, und mit einer im Bereich der pumpenseitigen Begrenzungswand des Materialaufgabebehälters angeordneten, über dessen Öffnungsrand überstehenden Spritzschutzeinrichtung.The invention relates to a truck-mounted concrete pump with a chassis designed as a truck chassis, with a bearing block arranged in the front region of the chassis, with a bearing block rotatable about a vertical axis and pivotable about a horizontal axis, consisting of a plurality of mast arms pivotable to a limited extent about horizontal axes, in the collapsed state on at least one support point, which is preferably designed as a mast support bracket, can be supported in the rear area of the chassis, with a material feed container, which is arranged near the rear end of the chassis and has an upward-facing filler opening, with a suction side in the area of a pump-side boundary wall on the Material feed container connected and connected on the pressure side with a concrete pump extending over the delivery mast, and with a in the area of the pump-side limit Enzungswand the material feed container arranged, protruding beyond the opening edge splash guard.
Bei bekannten Autobetonpumpen (vgl. DE-A-2 728 420) ist die Spritzschutzeinrichtung meist als auf der Pumpenseite des Materialaufgabebehälters fest installierter Blechkasten ausgebildet, der dafür sorgt, daß die beim Pumpen des Betons innerhalb des Materialaufgabebehälters entstehenden Betonspritzer nicht in den Maschinenbereich gelangen können. Es hat sich jedoch gezeigt, daß ein wirksamer Spritzschutz nur bei einer ausreichenden Bauhöhe des Blechkastens erzielt werden kann. Dies erfordert andererseits einen ausreichenden Freiraum unter dem auf dem Fahrgestell abgestützten Verteilermast, der vor allem bei großen Verteilermasten nicht immer zur Verfügung steht. Im Fahrzustand wird die Einfüllöffnung des Materialaufgabebehälters oft mit Hilfe einer als Gummimatte ausgebildeten Trichterabdeckung verschlossen. Dadurch wird ein Herausspritzen von Beton während des Fahrens sowie eine zu schnelle Aushärtung des Betons beispielsweise durch Sonneneinstrahlung vermieden.In known truck-mounted concrete pumps (cf. DE-A-2 728 420), the spray protection device is usually designed as a sheet metal box permanently installed on the pump side of the material feed container, which ensures that the concrete splashes that occur when the concrete is pumped inside the material feed container do not get into the machine area can. However, it has been shown that effective splash protection can only be achieved with a sufficient overall height of the sheet metal box. On the other hand, this requires sufficient space under the placing boom supported on the chassis, which is not always available, especially with large placing booms. In the driving state, the filling opening of the material feed container is often closed with the aid of a funnel cover designed as a rubber mat. This prevents concrete from spraying out while driving and too rapid hardening of the concrete, for example due to solar radiation.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Spritzschutzeinrichtung für den Materialaufgabebehälter einer Autobetonpumpe zu entwickeln, die unabhängig von der Größe des Verteilermasts sowohl im Arbeitszustand als auch im Fahrzustand einen wirksamen Spritzschutz gewährleistet.Proceeding from this, the object of the invention is to develop a spray protection device for the material feed container of a truck-mounted concrete pump, which guarantees effective spray protection both in the working state and in the driving state, regardless of the size of the placing boom.
Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Further advantageous refinements and developments of the invention result from the subclaims.
Die erfindungsgemäße Lösung geht von dem Gedanken aus, daß der Spritzschutz nur während des Pumpvorgangs, also bei stehender Autobetonpumpe und angehobenem Verteilermast eine ausreichende Bauhöhe erfordert, um Betonspritzer aufzufangen. Beim Fahrbetrieb, bei welchem der Verteilermast zusammengeklappt und auf dem Mastauflagebock abgestützt ist, bedarf es einer solchen Bauhöhe der Spritzschutzeinrichtung jedoch nicht. Deshalb wird gemäß der Erfindung vorgeschlagen, daß die Spritzschutzeinrichtung einen auf der pumpenseitigen Begrenzungswand des Materialaufgabebehälters angeordneten, über deren Öffnungsrand etwas überstehenden starren Wandaufbau aufweist, und daß im Bereich der von der Einfüllöffnung einen Abstand aufweisenden Oberkante des Wandaufbaus eine um eine quer zum Fahrgestell verlaufende horizontale Achse verschwenkbare starre Klappwand angelenkt ist, deren Schwenkbereich sich mit dem des zusammengeklappten Verteilermasts überschneidet und die bei von seiner Stützstelle abgehobenem Verteilermast von einer die Behälteröffnung zumindest teilweise übergreifenden Fahrtstellung in eine gegenüber dieser um ca. 90° hochgeklappten Arbeitsstellung begrenzt verschwenkbar und in den genannten Stellungen arretierbar ist. Die Klappwand weist hierbei eine Doppelfunktion auf: In der Arbeitsstellung stellt sie einen ausreichend hohen Spritzfänger dar, während sie in der Fahrtstellung als Behälterabdeckung dient. Der zur Lagerung der Klappwand notwendige starre Wandaufbau weist eine so geringe Bauhöhe auf, daß der Verteilermast beim Abstützen auf demThe solution according to the invention is based on the idea that the splash guard only requires a sufficient overall height to absorb concrete splashes during the pumping process, that is to say when the truck-mounted concrete pump is standing and the placing boom is raised. When driving, in which the placing boom folded and supported on the mast support, however, such a height of the splash guard is not required. It is therefore proposed according to the invention that the spray protection device has a rigid wall structure which is arranged on the pump-side boundary wall of the material feed container and has a projecting rigid wall structure beyond the opening edge thereof, and that in the area of the upper edge of the wall structure which is at a distance from the filling opening, a horizontal one running transversely to the chassis Axis pivotable rigid folding wall is articulated, the pivoting range of which overlaps with that of the folded distribution boom and which, when the distribution boom is lifted from its support point, can be pivoted to a limited extent from a travel position at least partially overlapping the container opening into a working position which is folded up by approximately 90 ° and in the positions mentioned can be locked. The folding wall has a dual function: in the working position it represents a sufficiently high splash guard, while in the driving position it serves as a container cover. The rigid wall structure necessary for mounting the folding wall has such a low overall height that the placing boom is supported on the
Mastauflagebock bis nahe zur Einfüllöffnung des Materialaufgabebehälters abgesenkt werden kann.Mast support bracket can be lowered close to the feed opening of the material feed container.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß der Wandaufbau durch zwei Seitenwangen begrenzt ist, die über den Öffnungsrand der zur pumpenseitigen Begrenzungswand senkrechten Seitenwände des Materialaufgabebehälters überstehen, während die Klappwand die Gestalt eines zur Seite der Gelenkachse und zur Einfüllöffnung hin wandoffenen Kastens aufweist, dessen Seitenwände beim Verschwenken der Klappwand parallel zu den Seitenwangen des Wandaufbaus unter paarweiser gegenseitiger Überlappung verschwenkbar sind.A preferred embodiment of the invention provides that the wall structure is delimited by two side walls, which extend beyond the opening edge of the pump side Boundary wall vertical side walls of the material feed container protrude, while the folding wall has the shape of a box open to the side of the hinge axis and to the filling opening, the side walls of which are pivotable when the folding wall is pivoted parallel to the side walls of the wall structure with mutual overlap in pairs.
Um das Anheben der Klappwand von ihrer Fahrtstellung in die Arbeitsstellung zu erleichtern, greift an der Klappwand eine in Richtung Arbeitsstellung wirkende Feder an. Die Feder ist dabei zweckmäßig als zwischen der Klappwand und einer fahrgestellfesten Stelle eingespannte, auf die Klappwand ein in Richtung Arbeitsstellung weisendes Drehmoment ausübende Zugfeder ausgebildet.In order to facilitate the lifting of the folding wall from its travel position into the working position, a spring acting on the folding wall acts in the direction of the working position. The spring is expediently designed as a tension spring which is clamped between the folding wall and a location fixed to the chassis and exerts a torque pointing towards the working position on the folding wall.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist zwischen der Klappwand und einem fahrgestellfesten Teil, vorzugsweise an der Stützstelle des Verteilermasts, eine Rastvorrichtung angeordnet, die in der Arbeitsstellung der Klappwand selbsttätig einrastet. Vorteilhafterweise ist die Rastvorrichtung unter der Einwirkung des in Richtung Stützstelle schwenkenden zusammengeklappten Verteilermasts selbsttätig lösbar, wobei die Klappwand nach dem Lösen der Rastverbindung vorzugsweise unter der Einwirkung des in Richtung Stützstelle schwenkenden Verteilermasts aus ihrer Arbeitsstellung in Richtung Fahrtstellung geschwenkt wird. Die Rastvorrichtung weist vorteilhafterweise ein vorzugsweise am fahrgestellfesten Teil angeordnetes feststehendes Rastorgan und ein vorzugsweise an der Klappwand angeordnetes, auf das feststehende Rastorgan über eine Auflaufschräge selbsttätig aufrastbares, begrenzt um eine horizontale Achse schwenkbares Rastorgan auf. Das schwenkbare Rastorgan kann dabei als mit einer im Rastzustand nach unten randoffenen, unter der Einwirkung der Schwerkraft und/oder einer Feder auf das feststehende Rastorgan aufrastbaren Rastaussparung versehener Schwenkhebel ausgebildet sein, der über ein entgegen der Kraft einer Feder vorzugsweise unter der Einwirkung des in Richtung Stützstelle schwenkenden Verteilermasts auslösbares Betätigungsorgan in seine ausgerastete Stellung verschwenkbar ist. Das Betätigungsorgan weist zweckmäßig eine an der Klappwand geführte, am einen Hebelarm des zweiarmigen Schwenkhebels angelenkte, mit seinem freien Ende über den Klappwandrand überstehende federbelastete Schubstange auf. Das selbsttätige Ver-. schwenken der Klappwand von der Arbeitsstellung in die Fahrtstellung wird dadurch erleichtert, daß die Klappwand in der Arbeitsstellung bezüglich des Fahrgestells schräg nach hinten oben und in der Fahrstellung im wesentlichen parallel zur Ebene der Einfüllöffnung schräg nach hinten unten weist.According to a further advantageous embodiment of the invention, a latching device is arranged between the folding wall and a part fixed to the chassis, preferably at the support point of the placing boom, which latches automatically in the working position of the folding wall. Advantageously, the latching device is automatically detachable under the action of the folded distribution mast pivoting in the direction of the support point, the folding wall, after releasing the latching connection, preferably being pivoted out of its working position in the direction of the driving position under the action of the distribution mast pivoting in the direction of the support point. The latching device advantageously has a preferably fixed locking element arranged on the chassis-fixed part and a locking element preferably arranged on the folding wall and which can be automatically locked onto the fixed locking element via a run-up slope and pivotable to a limited extent about a horizontal axis. The pivotable latching element can be designed as a pivoting lever which is open at the edge in the latching state and is open under the action of gravity and / or a spring and can be snapped onto the fixed latching member and which, via a counter to the force of a spring, preferably under the action of in the direction Support point pivoting distributor mast triggerable actuator is pivoted into its disengaged position. The actuating member expediently has a spring-loaded push rod guided on the folding wall, articulated on a lever arm of the two-armed pivot lever and projecting with its free end beyond the edge of the folding wall. The automatic Ver. pivoting the folding wall from the working position to the driving position is facilitated in that the folding wall in the working position with respect to the chassis obliquely backwards upwards and in the driving position substantially parallel to the level of the filling opening obliquely backwards downwards.
Eine Verbesserung des Spritzschutzes sowohl in der Arbeitsstellung als auch in der Fahrtstellung kann dadurch erzielt werden, daß die kastenförmige Klappwand in Fahrtstellung nur einen Teil der Einfüllöffnung übergreift und an der freien Unterkante ihrer der Gelenkachse gegenüberliergenden Seitenwand einen in Fahrtstellung den freien Teil der Einfüllöffnung übergreifenden Lappen aufweist, der zweckmäßig an der Seitenwandunterkante so pendelartig angelenkt ist, daß er in der Arbeitsstellung der Klappwand senkrecht nach unten hängt und in der Fahrtstellung den freien Teil der Einfüllöffnung parallel übergreift.An improvement in the splash guard both in the working position and in the driving position can be achieved in that the box-shaped folding wall engages over only part of the filler opening in the driving position and on the free lower edge of the joint axis opposite side wall has a rag in the driving position overlapping the free part of the filling opening, which is expediently articulated on the lower edge of the side wall so that it hangs vertically downwards in the working position of the folding wall and overlaps the free part of the filling opening in parallel in the driving position.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung kann die Klappwand mit einem von einander überlappenden Gummiplatten übergriffenen Durchbruch für den Durchgriff von über die Einfüllöffnung überstehenden Einbauteilen des Materialaufgabebehälters versehen werden. Bei diesen Einbauteilen handelt es sich beispielsweise um den oberen Teil eines C-Rohrschiebers der Betonpumpe und/oder um den Reinigungsstutzen der in den Materialaufgabebehälter eingreifenden Förderleitung.According to a further advantageous embodiment of the invention, the folding wall can be provided with an opening, overlapped by mutually overlapping rubber plates, for the penetration of built-in parts of the material feed container protruding beyond the filling opening. These built-in parts are, for example, the upper part of a C-tube slide of the concrete pump and / or the cleaning nozzle of the delivery line engaging in the material feed container.
Zur Arretierung der Klappwand in Fahrtstellung ist die Klappwand vorzugsweise mittels seitlicher Schnellverschlüsse oder Haubenzüge mit dem Materialaufgabebehälter lösbar verbindbar.To lock the hinged wall in the travel position, the hinged wall can preferably be detachably connected to the material feed container by means of lateral quick-release fasteners or hood pulls.
Der Materialaufgabebehälter kann zusätzlich durch eine außerhalb des starren Wandaufbaus über den Öffnungsrand nach oben überstehende, zum Wandaufbau hin offene Schürze vorzugsweise aus Gummi begrenzt werden, die die Klappwand in ihrer Fahrtstellung teilweise übergreift.The material feed container can additionally be delimited, preferably made of rubber, by an apron which protrudes upwards beyond the rigid wall structure beyond the opening edge and is open towards the wall structure and which partially overlaps the folding wall in its driving position.

Die Autobetonpumpe besteht im wesentlichen aus einem als LKW-Chassis ausgebildeten Fahrgestell 10 mit Führerhaus 12, einem im vorderen Teil des Fahrgestells 10 angeordneten Lagerbock 14, an welchem ein aus mehreren zusammenklappbaren Mastarmen 16 bestehender Verteilermast 18 um eine vertikale Achse 20 drehbar und eine horizontale Achse 22 schwenkbar gelagert ist, einem in der Nähe des rückwärtigen Endes des Fahrgestells 10 angeordneten Materialaufgabebehälter 24 und einer saugseitig an den Materialaufgabebehälter 24 angeschlossenen und druckseitig mit einer sich über den Verteilermast 18 erstreckenden Förderleitung 26 verbundenen, als Zweizylinder-Kolbenpumpe ausgebildeten Betonpumpe 28. Der Materialaufgabebehälter 24 weist eine schräg nach hinten oben weisende, mit einem nicht dargestellten Gitterrost abgedeckte Einfüllöffnung 30 auf, die durch einen flanschartigen Öffnungsrand 32 begrenzt ist.The truck-mounted concrete pump essentially consists of a
Der Materialaufgabebehälter 24 ist außerdem mit einer Spritzschutzeinrichtung versehen, die einen im Bereich der pumpenseitigen Begrenzungswand 34 angeordneten, über deren Öffnungsrand 32 überstehenden, im Querschnitt U- förmigen starren Wandaufbau 36 sowie eine um eine im Bereich der Oberkante des Wandaufbaus 36 quer zum Fahrgestell 10 verlaufende horizontale Achse 38 verschwenkbare Klappwand 40 aufweist. Der Wandaufbau 36 ist durch zwei Seitenwangen 42 begrenzt, die über den Öffnungsrand 32 der zur pumpenseitigen Begrenzungswand 34 senkrechten Seitenwände 44 des Materialaufgabebehälters 24 überstehen. Die Klappwand 40 hat die Gestalt eines zur Seite ihrer Gelenkachse 38 und zur Einfüllöffnung 30 hin wandoffenen Kastens, dessen Seitenwände 46 beim Verschwenken der Klappwand 40 parallel zu den Seitenwangen 42 des Wandaufbaus 36 unter paarweise gegenseitiger Überlappung verschwenkbar sind (vgl. Fig. 3 und 4). Der Schwenkbereich der Klappwand 40 überschneidet sich mit dem Schwenkbereich des Verteilermasts 18, so daß die Klappwand nur bei von seinem Mastauflagebock 48 abgehobenem Verteilermast 18 von ihrer die Einfüllöffnung 30 übergreifenden Fahrtstellung (Fig. 1 und 3) in ihre gegenüber dieser um ca. 90° hochgeklappte Arbeitsstellung (Fig. 2 und 4) verschwenkt werden kann. Da die kastenförmige Klappwand in ihrer Fahrtstellung (Fig. 1 und 3) nur einen Teil der Einfüllöffnung 30 übergreift, weist sie an der freien Unterkante 50 ihrer der Gelenkachse 38 gegenüberliegenden Stirnseitenwand 52 einen in Fahrtstellung den freien Teil der Einfüllöffnung 30 übergreifenden Lappen 54 auf, der beispielsweise aus einer starren Metallplatte oder aus einer Gummimatte bestehen kann. Der Lappen 54 ist an der Stirnseitenwand 52 so pendelartig angelenkt, daß er in der Arbeitsstellung der Klappwand (Fig. 2 und 4) senkrecht nach unten hängt und in der Fahrtstellung (Fig. 1 und 3) den freien Teil der Einfüllöffnung parallel übergreift. Weiter ist der Materialaufgabebehälter 24 durch eine außerhalb des starren Wandaufbaus 36 über den Öffnungsrand 32 nach oben überstehende, zum Wandaufbau 36 hin randoffene Schürze 56 vorzugsweise aus Gummi begrenzt. In Fahrtstellung ist die Klappwand durch je einen im Bereich der Schürze 56 angeordneten Haubenzug 58 mit dem Materialaufgabebehälter 54 verbunden. Zur Erleichterung des Öffnungsvorgangs greift an der Klappwand 40 eine Zugfeder 60 an, die mit ihrem anderen Ende an einer fahrgestellfesten Stelle 62 im Bereich des Mastauflagebocks 48 befestigt ist.The
Zur Arretierung der Klappwand 40 in der Arbeitsstellung ist eine selbsttätig einrastbare Rastvorrichtung vorgesehen, die einen an der Außenseite der Klappwand angelenkten zweiarmigen Schwenkhebel 64 mit Auflaufschräge 66 und randoffener Rastaussparung 68 sowie einen am Mastauflagebock 48 starr überstehenden Rastbügel 70 zum Einrasten des Schwenkhebels 64 aufweist. Der Schwenkhebel 64 ist zum Lösen der Rastverbindung über eine an der Außenseite der Klappwand 40 geführte, an einem Betätigungsarm 72 des Schwenkhebels angelenkte Betätigungsstange 76 entgegen der Kraft einer Zugfeder 74 betätigbar. Diese Betätigung erfolgt entweder von Hand oder unter der Einwirkung des auf seinen Mastauflagebock 48 niederschwenkenden Verteilermasts 18. Die Klappwand 40 ist so schräg nach oben weisend angeordnet, daß sie durch den nach unten schwenkenden Verteilermast 18 in Richtung Fahrtstellung verschwenkt wird, ohne dabei beschädigt zu werden.To lock the
