Gehäuse für ein Hydraulikaggregat Housing for a hydraulic unit
Die Erfindung betrifft ein Gehäuse für ein Hydraulikaggregat. The invention relates to a housing for a hydraulic unit.
Hydraulikaggregate, insbesondere Hochdruckhydraulikaggregate, werden im Allgemeinen verwendet, um hydraulisch kolbenbetätigte Hydraulic power units, especially high pressure hydraulic power units, are generally used to hydraulically piston actuated
Drehmomentschrauber, sogenannte Kraftschrauber.anzutreiben. Darüber hinaus dienen sie zum Spannen von Dehnzylindern und dergleichen. Es existieren sogenannte Einschlauch-Systeme, bei denen der Vorhub mittels Hydraulikkraft erfolgt, der Rückhub des Kolbens erfolgt in diesem Falle mittels Federkraft. Darüber hinaus gibt es aber auch Systeme, bei denen sowohl der Vorhub als auch der Rückhub des Kolbens mittels hydraulischer Kraft erfolgen. Torque wrench, so-called Kraftschrauber.anzutreiben. In addition, they serve for tensioning stretch cylinders and the like. There are so-called one-hose systems in which the preliminary stroke by means of hydraulic force, the return stroke of the piston takes place in this case by means of spring force. In addition, there are also systems in which both the forward stroke and the return stroke of the piston take place by means of hydraulic force.
Derartige Hochdruckhydraulikaggregate werden beispielsweise mittels Elektromotoren oder Pneumatikmotorenangetrieben. Dabei kommen sowohl bürstenlose Gleichstrommotoren oder auch Drehstrommotoren, ferner sogenannte Unterölmotoren zum Einsatz. Aus dem Stand der Technik ist es bekannt, diese Systeme zum Schutz mit einem sogenannten Rohrrahmen zu versehen. Dieser umschließt zumeist den Motor und die Bedienelemente. Gleichzeitig dient er zur Aufnahme von Anschlusskabeln und Kabeln für Fernbedienung. Such high-pressure hydraulic units are driven, for example, by means of electric motors or pneumatic motors. Both brushless DC motors or three-phase motors, and so-called sub-oil engines are used. From the prior art it is known to provide these systems for protection with a so-called tubular frame. This usually encloses the engine and the controls. At the same time, it is used to hold connecting cables and cables for remote control.
BESTÄTIGUNGSKOPIE
Problematisch hierbei ist es, dass ein derartiger Rohrrahmen keinen Schutz gegen vorstehende Hindernisse bietet, die beispielsweise auftreten, wenn das Hydraulikaggregat an einem Seil zu einem Arbeitsplatz, beispielsweise mit Hilfe eines Krans, gezogen werden muss. Dabei kommt es sehr häufig vor, dass insbesondere die Schlauchanschlüsse verbogen oder abgerissen werden. Darüber hinaus entstehen Beschädigungen an den elektrischen Leitungen und den Netzanschlüssen und dergleichen. CONFIRMATION COPY The problem here is that such a tubular frame does not provide protection against protruding obstacles that occur, for example, when the hydraulic unit must be pulled on a rope to a workplace, for example by means of a crane. It happens very often that in particular the hose connections are bent or torn off. In addition, damage to the electrical lines and the power connections and the like.
Ein weiterer Nachteil ist darin zu sehen, dass ein Rohrrahmengestell keinerlei Schutz gegen unter hohem Druck ausströmende Hydraulikflüssigkeit bietet. Wird beispielsweise ein Bauteil aufgrund äußerer oder innerer Einwirkung beschädigt und tritt Hydraulikflüssigkeit unter hohem Druck aus, besteht eine erhebliche Verletzungsgefahr, da ein Flüssigkeitsstrahl unter einem sehr hohen Druck eine immense Schneidwirkung entfaltet. Another disadvantage is the fact that a tubular frame frame offers no protection against high pressure hydraulic fluid flowing out. If, for example, a component is damaged due to external or internal action and if hydraulic fluid escapes under high pressure, there is a considerable risk of injury since a fluid jet under a very high pressure develops an immense cutting action.
Ein ganz wesentliches Problem eines Hydraulikaggregats mit einem derartigen Rohrrahmen stellt die Kühlung des Antriebmotors und des A very important problem of a hydraulic unit with such a tubular frame provides the cooling of the drive motor and the
Hydrauliköls dar. Das Hydrauliköl wird während des Betriebs sehr warm und kann Temperaturen bis zu 100 °C und mehr erreichen. Dies führt sehr oft dazu, dass Aggregate zwangsabgeschaltet werden, um so eine Abkühlung des Öls auf eine zulässige Maximaltemperatur zu bewirken. Eine solche Zwangsabschaltung ist nachteilig während des Betriebs des Hydraulic oil is very hot during operation and can reach temperatures of up to 100 ° C and more. This often leads to forced shut-off of aggregates in order to cool down the oil to a maximum permissible temperature. Such a forced shutdown is disadvantageous during the operation of the
Hydraulikaggregats. Sehr oft werden diese Aggregate nur durch Konvektion gekühlt. Hydraulic unit. Very often these units are only cooled by convection.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Gehäuse für ein derartiges Hydraulikaggregat zu vermitteln, welches zum einen einen besseren Schutz der Aggregate und Anbauteile, zum Beispiel Manometer, Ventile, Schlauchanschlüsse, gegen Einwirkungen von außen bietet. Das Gehäuse soll darüber hinaus eine Bedienungsperson in einem Leckagefall vor Verletzungen schützen. Eine ganz wesentliche Aufgabe ist es, eine
verbesserte Kühlung des Aggregats zur Erhöhung dessen Laufzeit zu vermitteln. The present invention is therefore based on the object to impart a housing for such a hydraulic unit, which on the one hand provides better protection of the units and attachments, for example, pressure gauge, valves, hose connections, against external influences. The housing is also intended to protect an operator in the event of a leak from injury. It is a very important task, one to provide improved cooling of the engine to increase its life.
Die Aufgabe wird erfindungsgemäß durch ein Gehäuse für ein The object is achieved by a housing for a
Hydraulikaggregat gelöst, welches durch eine allseits geschlossene Hydraulic unit solved, which by a completely closed
Gehäusewandung gekennzeichnet ist, in der wenigstens eine Einlassöffnung und wenigstens ein unabhängig von dem Hydraulikapparat betreibbarer Lüfter angeordnet sind. Unabhängig von dem Hydraulikapparat betreibbarer Lüfter bedeutet dabei gewissermaßen„Fremdlüfter", also ein Lüfter der betätigbar ist auch wenn das Hydraulikaggregat beispielsweise nicht eingeschaltet ist. Der Betrieb des Lüfters hängt also nicht vom Betrieb des Hydraulikaggregats und von dessen Funktionsfähigkeit ab, sondern stellt ein autarkes System dar. Durch die Ausbildung des Gehäuses als geschlossene Wandung mit wenigstens einer darin angeordneten Öffnung und wenigstens einem darin angeordneten Lüfter ist ein gezielter Luftstrom durch das Gehäuse erzielbar, wobei das Gehäuse gleichzeitig das Aggregat und die Anbauteile gegen Beschädigungen von außen schützt und eine Housing is characterized in which at least one inlet opening and at least one independently operable by the hydraulic fan can be arranged. Regardless of the hydraulic apparatus operable fan means to a certain extent "external fan", that is, a fan is actuated even if the hydraulic unit is not turned on.The operation of the fan does not depend on the operation of the hydraulic unit and its functionality, but provides a self-sufficient system By the formation of the housing as a closed wall with at least one opening disposed therein and at least one fan disposed therein a targeted air flow through the housing can be achieved, the housing simultaneously protects the unit and the attachments against damage from the outside and a
Bedienungsperson vor unter hohem Druck austretendem Hydrauliköl geschützt wird. Operator is protected from high pressure escaping hydraulic oil.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im unabhängigen Anspruch angegebenen Vorrichtung möglich. So sieht eine sehr vorteilhafte Ausgestaltung vor, dass der wenigstens eine Lüfter Umgebungsluft durch das Gehäuse saugt. Rein prinzipiell wäre es möglich, den Lüfter so zu betreiben, dass er Umgebungsluft in das Gehäuse hineinbläst. Dies würde jedoch zu einer turbulenten Strömung im Gehäuse führen. Der Luftstrom würde verwirbelt und müsste über die eine oder mehrere in der Gehäusewand angeordnete Öffnung(en) wieder austreten. Wesentlich effektiver lässt sich eine Kühlung dadurch erzielen, dass der Luftstrom durch das Gehäuse gesaugt wird. In diesem Falle saugt der wenigstens eine Lüfter Luft vom Inneren des Gehäuses nach außen in die Umgebung ab. Aufgrund des
hierdurch entstehenden Unterdrucks strömt Luft von der Umgebung durch die wenigstens eine Einlassöffnung in das Gehäuse. Hierdurch wird eine gezielte Strömung erzielt, die eine wesentlich effektivere Kühlung des The measures listed in the dependent claims advantageous refinements and improvements of the independent claim device are possible. Thus, a very advantageous embodiment provides that the at least one fan sucks ambient air through the housing. In principle, it would be possible to operate the fan so that it blows ambient air into the housing. However, this would lead to a turbulent flow in the housing. The airflow would be swirled and would have to exit through the one or more openings in the housing wall. Cooling can be achieved much more effectively by sucking the air flow through the housing. In this case, the at least one fan sucks air from the interior of the housing to the outside into the environment. Due to the Resulting negative pressure air flows from the environment through the at least one inlet opening into the housing. As a result, a targeted flow is achieved, which is a much more effective cooling of the
Hydraulikaggregats und seiner Komponenten ermöglicht. Hydraulic unit and its components allows.
Um die Strömung optimal an die Kühlungserfordernisse anzupassen, kann vorgesehen sein, die Größe der wenigstens einen Öffnung an einen vorgegebenen Luftstrom anzupassen. In order to optimally adapt the flow to the cooling requirements, it may be provided to adapt the size of the at least one opening to a predetermined air flow.
Darüber hinaus ist vorteilhafter Weise vorgesehen, dass die wenigstens eine Öffnung und der wenigstens eine Lüfter so in der Gehäusewand angeordnet sind, dass eine möglichst lange Luftströmung durch das Gehäuse entsteht, wobei die strömende Luft an dem Hydraulikaggregat und seinen In addition, it is advantageously provided that the at least one opening and the at least one fan are arranged in the housing wall, that as long as possible air flow through the housing is formed, wherein the flowing air to the hydraulic unit and its
Komponenten vorbeigeführt wird. Components is passed.
Um mehrere Luftströme zu erzeugen, kann darüber hinaus gemäß einer Ausführungsform eine Mehrzahl von an unterschiedlichen Positionen in der Gehäusewand angeordneten Öffnungen vorgesehen sein. In diesem Falle werden von dem wenigstens einen Lüfter mehrere hin zum Lüfter geführte Strömungen erzeugt, die aufgrund der Positionierung der Öffnungen in der Gehäusewand gezielte Ströme über unterschiedliche Teile des Moreover, according to one embodiment, in order to generate a plurality of air streams, a plurality of openings arranged at different positions in the housing wall may be provided. In this case, a plurality of flows directed towards the fan are generated by the at least one fan, which, due to the positioning of the openings in the housing wall, generates targeted flows over different parts of the fan
Hydraulikaggregats oder dessen Komponenten ermöglichen. Hydraulic unit or its components allow.
Gemäß einer weiteren Ausgestaltung kann vorgesehen sein, dass auch eine Mehrzahl von an unterschiedlichen Positionen in der Gehäusewand angeordneten Lüftern vorgesehen sind. In diesem Falle sind sämtliche Lüfter getrennt voneinander betreibbar und stellen damit„Fremdlüfter" im oben angegebenen Sinne dar. Hierdurch wird die Kühlwirkung weiter verbessert. According to a further embodiment it can be provided that a plurality of fans arranged at different positions in the housing wall are also provided. In this case, all fans are operated separately from each other and thus represent "external fan" in the above sense. This further improves the cooling effect.
Rein prinzipiell kann die Gehäusewand in den unterschiedlichsten Materialien ausgeführt sein. Dabei können zum Beispiel hochfeste Kunststoffe zum Einsatz kommen oder Verbundwerkstoffe. Eine vorteilhafte Ausführungsform
sieht den Einsatz von Metall vor, welches insbesondere auf einfache Weise bearbeitbar ist. Dabei sind in der Gehäusewand elektrische Anschlüsse oder hydraulische Anschlüsse angeordnet und zwar so, dass eine Beschädigung weitestgehend vermieden wird. Die Anschlüsse sind in die Gehäusewand integriert. Darüber hinaus können in die Gehäusewand Anzeigeelemente, beispielsweise Manometer, integriert sein. In principle, the housing wall can be made in a variety of materials. For example, high-strength plastics or composite materials can be used. An advantageous embodiment provides for the use of metal, which in particular can be processed easily. In this case, electrical connections or hydraulic connections are arranged in the housing wall in such a way that damage is largely avoided. The connections are integrated in the housing wall. In addition, display elements, for example pressure gauges, can be integrated in the housing wall.
Weitere Vorteile und Merkmale der Erfindung werden nachfolgend in Further advantages and features of the invention are described below
Verbindung mit der Zeichnung erläutert, in welcher Figur 1 schematisch eine isometrische Darstellung eines erfindungsgemäßen Gehäuses und Figur 2 schematisch eine Schnittdarstellung des erfindungsgemäßen Gehäuses zeigen. Figure 1 illustrates schematically an isometric view of a housing according to the invention and Figure 2 shows schematically a sectional view of the housing according to the invention.
Ein von der Erfindung Gebrauch machendes, als Ganzes mit 100 A making use of the invention, as a whole with 100
bezeichnetes und in Figur 1 und Figur 2 dargestelltes Gehäuse weist eine allseits geschlossene Wandung 101 aus insbesondere Metall auf. Das Gehäuse kann beispielsweise im Wesentlichen die äußere Gestalt einer Tasche mit einem am oberen Ende angeordneten Tragegriff 102 aufweisen. Unterhalb des Tragegriffs 102 und durch diesen gewissermaßen geschützt sind Anschlüsse 200 für Hydraulikleitungen und/oder elektrische Leitungen. Darüber hinaus können ebenfalls im oberen Teil des Gehäuses oder auch an einer anderen Stelle Anzeigeelemente 300, beispielsweise Manometer, in die Gehäusewand 301 integriert sein. designated and shown in Figure 1 and Figure 2 housing has a well-closed wall 101 of particular metal. By way of example, the housing may essentially have the outer shape of a pocket with a carrying handle 102 arranged at the upper end. Below the handle 102 and protected by this to some extent are ports 200 for hydraulic lines and / or electrical lines. In addition, display elements 300, for example pressure gauges, can likewise be integrated into the housing wall 301 in the upper part of the housing or at another location.
In einer vorderen stirnseitigen Gehäusewand 101a ist eine Öffnung 120 für einen Lüfter 121 vorgesehen. Auf der dieser Gehäusewand 101 a In a front end-side housing wall 101 a, an opening 120 for a fan 121 is provided. On this housing wall 101 a
gegenüberliegenden anderen stirnseitigen Gehäusewand 101 b ist wenigstens eine Einlassöffnung 110 angeordnet. opposite other front-side housing wall 101 b at least one inlet opening 110 is arranged.
Die Einlassöffnung 110 und die Öffnung 120 für den Lüfter 121 sind so positioniert, dass ein möglichst langer Luftstrom und eine Luftführung über ein in dem Gehäuse 100 angeordnetes Hydraulikaggregat 400 entstehen. Der
Lüfter 121 wird dabei so betrieben, dass er Luft aus dem Inneren des The inlet opening 110 and the opening 120 for the fan 121 are positioned such that the longest possible air flow and an air guide are formed via a hydraulic unit 400 arranged in the housing 100. Of the Fan 121 is thereby operated so that it air from the interior of the
Gehäuses 100 in die Umgebung absaugt. Durch diesen Absaug-Prozess entsteht im Inneren des Gehäuses 100 ein Unterdruck. Es strömt auf diese Weise Luft aus der Umgebung durch die Öffnung 110 in das Gehäuse 100 ein, diese wird um das Hydraulikaggregat 400 geführt, bis sie wieder aus der Lüfteröffnung 120 ausströmt. Ein solcher Betrieb des Lüfters 121 ermöglicht eine gezielt führbare Strömung, die eine wesentlich effektivere Kühlung des Hydraulikaggregats 400 gegenüber einem umgekehrt betriebenen Lüfter, also einem Lüfter, der Luft in das Innere des Gehäuses bläst, ermöglicht. Siphons housing 100 into the environment. This suction process creates a negative pressure inside the housing 100. It flows in this way air from the environment through the opening 110 in the housing 100, this is guided around the hydraulic unit 400 until it flows out of the fan opening 120 again. Such operation of the fan 121 allows for a targeted feasible flow, which allows a much more effective cooling of the hydraulic unit 400 against a reversely operated fan, so a fan that blows air into the interior of the housing.
Die Stärke des Luftstroms kann dabei durch Variation der Größe der Öffnung 110 bestimmt werden. Darüber hinaus können mehr als eine Öffnung 110 in der Gehäusewand 101 b oder an einer anderen Stelle als Gehäusewandung 121 vorgesehen sein. Ferner ist es auch denkbar, mehr als einen Lüfter in der Gehäusewandung 101 vorzusehen. Durch die aufgrund der Saugwirkung geführte Luftströmung ist eine optimale Kühlung des Hydraulikaggregats 400 möglich.
The strength of the air flow can be determined by varying the size of the opening 110. In addition, more than one opening 110 may be provided in the housing wall 101 b or at a different location than the housing 121. Furthermore, it is also conceivable to provide more than one fan in the housing wall 101. By guided due to the suction air flow optimal cooling of the hydraulic unit 400 is possible.
