Description

Materialaufgabebehälter, insbesondere für DickstoffpumpenMaterial feed container, especially for thick matter pumps
Beschreibungdescription
Die Erfindung betrifft einen Materialaufgabebehälter, insbesondere für Dickstoffpumpen, mit einem einen Behälterboden, eine Stirnwand, eine Rückwand und zwei einander gegenüberliegende Seitenwände aufweisenden, nach oben of- fenen Behälterunterteil, und mit einem sich zwischen den beiden Seitenwänden durch das Behälterunterteil hindurch erstreckenden, mittels einer Achswelle in je einem die Seitenwände durchdringenden Drehlager gelagerten, durch mindestens einen auf der Behälteraußenseite angeordneten Motor antreibbaren Rührwerk.The invention relates to a material feed container, in particular for thick matter pumps, with a container bottom part which has a container bottom, an end wall, a rear wall and two opposite side walls and which is open at the top, and with a container part which extends between the two side walls and by means of a Axle shaft each in a rotary bearing which penetrates the side walls and which can be driven by at least one motor arranged on the outside of the container.
Bei einem bekannten Materialaufgabebehälter ist das Rührwerk in zwei behälterfesten Lagern gelagert und wird durch zwei auf der Behälteraußenseite angeordnete Hydrau- likmotoren angetrieben. Die Lager und die Motoren sind fest am Materialaufgabebehälter fest montiert . Bei einer Zweizylinder-Dickstoffpumpe verdeckt das Rührwerk im Materialaufgabebehälter die Rohrweiche der Pumpe und einen Teil der Pumpöffnungen. Um an diese Teile beispielsweise zu Wartungszwecken herankommen zu können, muß auch das Rührwerk entfernt werden. Zur Demontage des Rührwerks und der Motoren müssen zunächst die Rührwerksflügel von der Rührwerkswelle entfernt werden, bevor die Achswelle aus den Lagern herausgezogen werden kann. Hierzu müssen Befe- stigungsschrauben gelöst werden, mit denen die Rührwerks- flügel an der Achswelle befestigt sind. Nach längerem Pumpbetrieb sitzen die Schrauben aufgrund von Betonablagerungen meist so fest, daß sie nur mit Hilfe eines Schneidgeräts entfernt werden können.In a known material feed container, the agitator is mounted in two bearings fixed to the container and is driven by two hydraulic motors arranged on the outside of the container. The bearings and motors are firmly attached to the material feed container. In the case of a two-cylinder thick matter pump, the agitator in the material feed tank covers the pump switch and part of the pump openings. In order to be able to access these parts for maintenance purposes, for example, the agitator must also be removed. To dismantle the agitator and the motors, the agitator blades must first be removed from the agitator shaft before the axle shaft can be pulled out of the bearings. For this purpose, the fastening screws with which the agitator blades are fastened to the axle shaft must be loosened. After a long time Pump operation, the screws are usually so tight due to concrete deposits that they can only be removed with the help of a cutter.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, den bekannten Materialaufgabebehälter dahingehend zu verbessern, daß eine leichtere Zugänglichkeit zu den im Behälter befindlichen Bauteilen und Verschleißteilen ermöglicht wird.Proceeding from this, the object of the invention is to improve the known material feed container in such a way that easier access to the components and wearing parts located in the container is made possible.
Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Advantageous refinements and developments of the invention result from the dependent claims.
Der erfindungsgemäßen Lösung liegt der Gedanke zugrunde, daß das Rührwerk, dessen Lager und der mindestens eine Motor eine Baugruppe bilden, die als solche lösbar mit dem Behälterunterteil verbunden ist .The solution according to the invention is based on the idea that the agitator, its bearing and the at least one motor form an assembly which, as such, is detachably connected to the lower part of the container.
Gemäß einer bevorzugten Ausgestaltung der Erfindung sind die Drehlager zu diesem Zweck in je einem Lagerblock angeordnet, während die Seitenwände je eine nach oben randoffene Ausnehmung zur flüssigkeitsdichten Aufnahme eines der in ihrer Außenkontur an die Innenkontur der Ausnehmung angepaßten Lagerblδcke aufweisen. Um eine verwin- dungsfreie Kraftübertragung zwischen den Lagerblδcken und dem Behälterunterteil zu gewährleisten, wird gemäß einer vorteilhaften Ausgestaltung der Erfindung vorgeschlagen, daß die Lagerblδcke unter parallel zu den Seitenwänden ausgerichteter Krafteinleitung formschlüssig mit den Sei- tenwänden verbindbar sind. Vorteilhafterweise weist die Ausnehmung eine zumindest partiell über die Seitenwand auf der Behälteraußenseite überstehende Randpartie mit einer an die Außenkontur des Lagerblocks angepaßten In- nenkontur auf, wobei zwei einander gegenüberliegende Teile der Randpartie mit Durchbrüchen versehen sein können, die miteinander und mit einer im Lagerblock befindlichen Querbohrung fluchten und durch die eine Spannschraube zur Fixierung des Lagerblocks in der Ausnehmung hindurch- steckbar ist. Auf diese Weise ist es möglich, durch Lösen von lediglich zwei Spannschrauben die Rührwerksbaugruppe vom Behälterunterteil abzutrennen, so daß sie beispielsweise mit Hilfe eines Hebezeugs oder eines Krans aus diesem herausgehoben werden kann.According to a preferred embodiment of the invention, the rotary bearings are arranged in a respective bearing block for this purpose, while the side walls each have an upwardly open recess for the liquid-tight reception of one of the bearing blocks adapted in their outer contour to the inner contour of the recess. In order to ensure a torsion-free transmission of force between the bearing blocks and the lower part of the container, it is proposed according to an advantageous embodiment of the invention that the bearing blocks form-fit with the sides under the introduction of force parallel to the side walls. tenwalls are connectable. The recess advantageously has an edge portion which at least partially projects beyond the side wall on the outside of the container and has an inner contour adapted to the outer contour of the bearing block, it being possible for two parts of the edge portion lying opposite one another to be provided with openings which are connected to one another and with a transverse bore in the bearing block aligned and through which a clamping screw can be inserted to fix the bearing block in the recess. In this way, it is possible to separate the agitator assembly from the lower part of the container by loosening only two clamping screws, so that it can be lifted out of the lower part, for example with the aid of a lifting device or a crane.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die Achswelle an ihren durch die Lager flüssigkeitsdicht hindurchgeführten Enden lösbar mit der Abtriebswelle je eines Motors gekuppelt ist. Die Motoren können dabei mit ihrem Motorgehäuse am benachbarten Lagerblock angeflanscht werden. Um die beim Rühren von Beton auftretenden hohen Drehmomente aufnehmen zu können, weisen die Motoren zweckmäßig eine im wesentlichen radial über das Motorgehäuse überstehende, formschlüssig an der betreffenden Seitenwand verankerbare Drehmomentstütze auf.A further advantageous embodiment of the invention provides that the axle shaft is detachably coupled to the output shaft of one motor at each of its ends which are passed through the bearings in a liquid-tight manner. The motors can be flanged to the adjacent bearing block with their motor housing. In order to be able to absorb the high torques which occur when concrete is being stirred, the motors expediently have a torque support which projects essentially radially beyond the motor housing and can be positively anchored to the relevant side wall.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist ein auf die Oberkante des Behälterunterteils lösbar aufsetzbarer, wahlweise mit dem Behälterunterteil und/oder mit den Lagerhaltern verbindbarer, nach oben und unten offener Behälteraufsatz vorgesehen. Mit dieser Maßnahme kann die Behälterhδhe vergrößert und zugleich erreicht werden, daß der Behälteraufsatz entweder mit oder ohne Rührwerksbaugruppe vom Behälterunterteil beispiels- weise zu Reinigungs- und Wartungszwecken abgenommen werden kann.According to a further preferred embodiment of the invention, a detachable mountable on the upper edge of the lower container part, optionally connectable to the lower container part and / or to the bearing holders, is upwards and open container attachment provided below. With this measure, the container height can be increased and at the same time it can be achieved that the container attachment can be removed from the lower part of the container, either with or without an agitator assembly, for cleaning and maintenance purposes, for example.
Vorteilhafterweise sind das Behälterunterteil und der Behälteraufsatz an im Randbereich der Stirn- und Rückwand überstehenden Flanschpartien miteinander verbindbar. Zweckmäßig weist hierzu die an der Rückwand des Behälterunterteils überstehende Flanschpartie mindestens zwei randoffene und die über die Stirnwand überstehende Flanschpartie mindestens zwei geschlossene Durchbrüche für den Durchtritt je einer die Flanschpartie des Behälteraufsatzes durchdringenden Flanschschraube auf. Um den Behälteraufsatz gegenüber dem Behälterunterteil verschwenken zu können, sind zumindest die stirnwandseitigen Flanschschrauben am Behälteraufsatz angeflanscht.The bottom part of the container and the top part of the container can advantageously be connected to one another at flange portions projecting in the edge region of the front and rear walls. For this purpose, the flange section projecting on the rear wall of the lower container part expediently has at least two open edges and the flange section projecting beyond the end wall has at least two closed openings for the passage of one flange screw penetrating the flange section of the container attachment. In order to be able to pivot the container attachment with respect to the lower part of the container, at least the flange screws on the end wall are flanged to the container attachment.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Behälteraufsatz über im Bereich seiner Unterkante seitenwandseitig nach außen überstehende Flanschpartien mit je einem der Lagerblöcke lösbar ver- bindbar. Zu diesem Zweck weist der Behälteraufsatz im Bereich seiner seitenwandseitig überstehenden Flanschpartie mindestens eine mit einer Schraubbohrung des Lagerblocks fluchtende Bohrung für eine Befestigungsschraube auf.According to a further advantageous embodiment of the invention, the container attachment can be detachably connected to one of the bearing blocks in each case via flange portions projecting outwards in the region of its lower edge on the side wall side. For this purpose, the container attachment has in the region of its flange section projecting at the side wall at least one bore for a fastening screw aligned with a screw bore of the bearing block.
Zur flüssigkeitsdichten Abdichtung des Behälters im Bereich der Rührwerkslager ist es von Vorteil, wenn zwi- sehen den in ihrer Kontur aufeinander abgestimmten Trennflächen des Lagerblocks und der Ausnehmung ein umlaufender Dichtring angeordnet ist .

Der Materialaufgabebehälter 20 ist in ein Behälterunterteil 38 und einen Behälteraufsatz 40 unterteilt, die über eine Flanschverbindung 42 lösbar miteinander verbunden sind. In dem Materialbehälter befindet sich ein Rührwerk 44, dessen Achswelle 46 durch außenliegende Hydromotoren 48 angetrieben ist und sich zwischen den Seitenwänden 50 des Behälterunterteils durch das Behälterinnere hindurch erstreckt. Die Achswelle 46 trägt wendelfδrmige Rührflügel 52, die das im Materialaufgabebehälter 20 befindliche dickflüssige Material durchmischen und zugleich zu den Fδrderzylinderöffnungen 24 hin fördern. Die Achswelle 46 greift mit ihren Enden 54 durch je ein Drehlager 56 hindurch, das in je einem Lagerblock 58 angeordnet ist. Die Hydromotoren 48 sind mit ihrem Gehäuse auf der dem Rühr- flügel 52 gegenüberliegenden Außenseite des zugehörigen Lagerblocks 58 starr befestigt und mit ihrer Abtriebswel- le 60 drehfest mit den Enden 54 der Achswelle 46 gekoppelt. Außerdem weisen die Hydromotoren 48 eine radial über das Motorgehäuse überstehende Drehmomentstütze 62 auf, mit der sie an einem an der Außenseite der Seitenwände 50 angeordneten Widerlager 64 formschlüssig ab- stützbar sind. Das Rührwerk 44 mit den Lagerblδcken 58 und den Hydromotoren 48 bilden eine Baugruppe, die lösbar in den Seitenwänden 50 des Behälterunterteils befestigbar ist. Zu diesem Zweck weisen die Seitenwände 50 je eine nach oben randoffene Ausnehmung 66 auf, die eine zur Au- ßenkontur der Lagerblöcke 58 komplementäre Innenkontur aufweisen. Jede der Ausnehmungen weist eine auf der Behälteraußenseite über die Seitenwand 50 überstehende Randpartie 68 mit einer an die Außenkontur des betreffenden Lagerblocks 58 angepaßten Innenkontur auf. Zwischen den in ihrer Kontur aufeinander abgestimmten Trennflächen 69 des Lagerblocks 58 und der Ausnehmung 66 ist ein um- laufender Dichtring 70 angeordnet, der in eine umlaufende Nut des Lagerblocks 58 eingesetzt ist. Zur Verankerung der Lagerblδcke 58 in den Ausnehmungen 66 sind zwei einander gegenüberliegende Teile der außenseitig überstehen- den Randpartie 68 mit Durchbrüchen 72 versehen, die miteinander und mit einer im Lagerblock 58 befindlichen Querbohrung 74 fluchten und durch die eine Spannschraube 76 zur Fixierung des Lagerblocks 58 in der Ausnehmung 66 hindurchsteckbar ist .The material feed container 20 is subdivided into a container lower part 38 and a container attachment 40, which over a flange connection 42 are releasably connected to one another. In the material container there is an agitator 44, the axle shaft 46 of which is driven by external hydraulic motors 48 and extends through the interior of the container between the side walls 50 of the lower part of the container. The axle shaft 46 carries helical agitator blades 52 which mix the viscous material located in the material feed container 20 and at the same time convey it to the feed cylinder openings 24. The ends of the axle shaft 46 pass through a rotary bearing 56, which is arranged in a bearing block 58. The hydraulic motors 48 are rigidly fixed with their housing on the outside of the associated bearing block 58 opposite the agitator blade 52 and with their output shaft 60 are non-rotatably coupled to the ends 54 of the axle shaft 46. In addition, the hydraulic motors 48 have a torque support 62 which projects radially beyond the motor housing and by means of which they can be positively supported on an abutment 64 arranged on the outside of the side walls 50. The agitator 44 with the bearing blocks 58 and the hydraulic motors 48 form an assembly which can be detachably fastened in the side walls 50 of the lower part of the container. For this purpose, the side walls 50 each have an upwardly open recess 66, which has an inner contour that is complementary to the outer contour of the bearing blocks 58. Each of the recesses has an edge portion 68 on the outside of the container projecting beyond the side wall 50 with an inner contour adapted to the outer contour of the bearing block 58 in question. Between the separating surfaces 69 of the bearing block 58 and the recess 66, which are coordinated in their contours, a running sealing ring 70 is arranged, which is inserted into a circumferential groove of the bearing block 58. To anchor the bearing blocks 58 in the recesses 66, two mutually opposite parts of the edge portion 68 projecting on the outside are provided with openings 72, which are aligned with one another and with a transverse bore 74 in the bearing block 58 and through which a clamping screw 76 for fixing the bearing block 58 in the recess 66 can be pushed through.
Das Behälterunterteil 38 und der Behälteraufsatz 40 sind mittels Flanschschrauben 78,80 über die rückwandseitigen und stirnwandseitigen Flanschpartien 82 , 84 lösbar miteinander verbunden (Fig. 3a) . Die rückwandseitige Flanschpartie 82 weist zu diesem Zweck zwei randoffene Durchbrüche auf, während die stirnseitige Flanschpartie 84 mit geschlossenen Durchbrüchen versehen ist . Die Flanschschrauben 78,80 sind mit ihren Köpfen an Laschen 86,88 des Behälteraufsatzes 40 angelenkt.The lower container part 38 and the container attachment 40 are detachably connected to one another by means of flange screws 78, 80 via the flange parts 82, 84 on the rear wall and front wall side (FIG. 3a). For this purpose, the rear-side flange section 82 has two openings that are open at the edge, while the front-side flange section 84 is provided with closed openings. The flange bolts 78, 80 are articulated with their heads to tabs 86, 88 of the container attachment 40.
Der Behälteraufsatz 40 ist außerdem über im Bereich seiner Unterkante seitenwandseitig nach außen überstehende Flanschpartien 90 mit den Lagerblδcken 58 lösbar verbindbar, und zwar mit je einer Befestigungsschraube 92, die durch einen Durchbruch in der betreffenden Flanschpartie 90 in eine am Lagerblock 58 befindliche Gewindebohrung 94 eindrehbar ist. Die an den Lagerblδcken 58 umlaufenden Dichtringe 70 liegen in diesem Bereich von unten her gegen die Flanschpartien 90 an. Der Behälteraufsatz 40 wird im Bereich seiner durchgehenden Öffnung von einem Gitterrost 96 übergriffen, der starr mit dem Behälteraufsatz 40 verbunden ist oder gegenüber diesem um eine stirnseitige Achse verschwenkbar ist.The container attachment 40 can also be releasably connected to the bearing blocks 58 via flange portions 90 projecting outward in the region of its lower edge, specifically with a fastening screw 92, which can be screwed into a threaded bore 94 located on the bearing block 58 through an opening in the relevant flange portion 90 . The sealing rings 70 running around the bearing blocks 58 lie in this area from below against the flange parts 90. The container attachment 40 is overlapped in the area of its continuous opening by a grating 96 which is rigidly connected to the container attachment 40 or can be pivoted relative to the latter about an end axis.
Mit den erfindungsgemäßen Maßnahmen ist es möglich, durch Lösen der Befestigungsschrauben 92 und der Flanschschraube 78 den Behälteraufsatz 40 zusammen mit dem Gitterrost 96 um die durch die Laschen 88 und die Flanschschrauben 80 gebildete stirnseitige Achse gegenüber dem Behälterunterteil 38 zu verschwenken (Fig. 3c) .With the measures according to the invention, it is possible, by loosening the fastening screws 92 and the flange screw 78, to pivot the container attachment 40 together with the grating 96 about the end axis formed by the tabs 88 and the flange screws 80 relative to the container lower part 38 (FIG. 3c).
Auf diese Weise ist es möglich, den Materialaufgabebehäl- ter nach Durchführung eines Pumpvorgangs zu Reinigungs- zwecken auszuspritzen. In diesem Falle verbleibt das Rührwerk 44 im Behälterunterteil 38.In this way, it is possible to spray the material feed container for cleaning purposes after a pumping process has been carried out. In this case, the agitator 44 remains in the lower container part 38.
Für Wartungszwecke im Bereich der Rohrweiche 34 ist es erwünscht, daß zusätzlich auch das Rührwerk 44 aus dem Behälter entfernt wird. Mit den vorbeschriebenen Maßnahmen kann das Rührwerk 44 zusammen mit dem Behälteraufsatz 40 vom Behälterunterteil 38 abgehoben werden (Fig. 3b) . Hierzu sind lediglich die vier Flanschschrauben 78,80 und die beiden Spannschrauben 76 zu lösen und der Behälteraufsatz 40 zusammen mit dem Rührwerk 44 beispielsweise mit Hilfe eines Krans vom Behälterunterteil 38 abzuheben. Nach Durchführung der Wartungsarbeiten kann dann der Behälteraufsatz 40 mit dem Rührwerk 44 in umgekehrter Rei- henfolge mit wenigen Handgriffen wieder auf das Behälterunterteil 38 aufgesetzt werden. Zusammenfassend ist folgendes festzuhalten: Die Erfindung bezieht sich auf einen Materialaufgabebehälter 20, insbesondere für Dickstoffpumpen, mit einem nach oben offenen Behälterunterteil 38 und einem sich zwischen zwei Seitenwänden 50 durch das Behälterunterteil 38 hindurch erstreckenden, motorisch antreibbaren Rührwerk 44. Um eine leichte Zugänglichkeit des Behälterinneren zu Wartungsund Reinigungszwecken zu ermöglichen, wird gemäß der Er- findung vorgeschlagen, daß das Rührwerk 44, dessen Drehlager 56 und dessen Antriebsmotor 48 eine Baugruppe bilden, die als solche lösbar mit dem Behälterunterteil 38 verbunden ist. Außerdem ist ein auf die Oberkante des Behälterunterteils 38 lösbar aufsetzbarer, wahlweise mit dem Behälterunterteil 38 und/oder mit der Rührwerksbaugruppe verbindbarer, nach oben und unten offener Behälteraufsatz 40 vorgesehen. Mit den erfindungsgemäßen Maßnahmen ist es möglich, den Behälteraufsatz 40 entweder ohne die Rührwerksbaugruppe gegenüber dem Behälterunter- teil 38 zu verschwenken bzw. abzuheben oder zusammen mit der Rührwerksbaugruppe vom Behälterunterteil 38 abzuheben. For maintenance purposes in the area of the tube switch 34, it is desirable that the agitator 44 is also removed from the container. With the measures described above, the agitator 44 can be lifted off the lower container part 38 together with the container attachment 40 (FIG. 3b). For this purpose, only the four flange screws 78, 80 and the two tensioning screws 76 have to be loosened and the container attachment 40 together with the agitator 44 can be lifted off the container lower part 38, for example with the aid of a crane. After the maintenance work has been carried out, the container attachment 40 with the agitator 44 can then be placed back onto the lower container part 38 in the reverse order in a few simple steps. In summary, the following can be stated: The invention relates to a material feed container 20, in particular for thick matter pumps, with an upwardly open lower container part 38 and a motor-driven agitator 44 which extends between two side walls 50 through the lower container part 38. In order to make the interior of the container easy to access To allow for maintenance and cleaning purposes, it is proposed according to the invention that the agitator 44, its pivot bearing 56 and its drive motor 48 form an assembly which as such is detachably connected to the lower container part 38. In addition, a container attachment 40 is provided which can be detachably placed on the upper edge of the lower container part 38 and which can be optionally connected to the lower container part 38 and / or to the agitator assembly. With the measures according to the invention, it is possible to either pivot or lift the container attachment 40 without the agitator assembly relative to the lower container part 38 or to lift it from the lower container part 38 together with the agitator assembly.
