Description

Die Erfindung betrifft einen Tragrahmen für zugmittelbetriebene Hebezeuge mit einer Seiltrommel, mit mindestens zwei zwischen zwei seitlichen Stimelementen angeordneten Längsträgern, deren Enden jeweils im Bereich der Stimelemente über die Längsträgerrichtung in ihrer Lage fixiert sind.The invention relates to a support frame for traction-powered hoists with a Rope drum, with at least two arranged between two lateral stimulating elements Longitudinal beams, the ends of each in the area of the stimulus over the Longitudinal direction are fixed in their position.

Ein derartiger Tragrahmen ist aus der DE 746 602 C bekannt, wobei die Stirnelemente hierbei plattenförmig ausgebildet sind.Such a support frame is known from DE 746 602 C, the end elements are plate-shaped.

Es ist bekannt, zugmittelbetriebene Hebezeuge, insbesondere elektrische Seilwinden, modular aus den Baugruppen Elektrik, Motor, Getriebe, Seiltrommel, Tragmittel und Tragrahmen aufzubauen, wobei die einzelnen Baugruppen in der Regel lösbar zusammensetzbar sind, was eine Vielzahl von Kombinationen ermöglicht. Am Tragrahmen sind die Hauptbaugruppen der Seilwinde befestigt; insbesondere nimmt er die Lagerungen und die Antriebswelle der Seiltrommel auf. Ein Tragrahmen besteht im wesentlichen aus zwei Stimplatten, die mit Abstand parallel zueinander angeordnet und an zwischen den Stimplatten angeordneten Längsträgern befestigt sind, wobei die Befestigung der Stirnplatten an den Längsträgem über mindestens drei Schraubverbindungen je Stimplatte erfolgt. Nachteilig ist bei diesem bekannten Tragrahmen für Seilwinden der durch die Schraubverbindungen bedingte relativ große Montageaufwand. Außerdem erfordert die in den Stirnplatten gelagerte Antriebswelle der Seiltrommel aufgrund der damit verbundenen mechanischen Belastungen des Tragrahmens massiv ausgebildete Längsträger, was zu einem großen Gewicht des Tragrahmens führt.It is known to use hoists operated by traction means, in particular electric winches, Modular from the electrical, motor, gearbox, cable drum, suspension element and To build support frame, the individual modules are usually detachable can be assembled, which enables a large number of combinations. On the support frame the main components of the winch are attached; in particular he takes the bearings and the drive shaft of the cable drum. A support frame consists essentially of two end plates that are spaced parallel to each other and between the End plates arranged longitudinal beams are attached, the attachment of the End plates on the longitudinal beams using at least three screw connections per end plate he follows. The disadvantage of this known support frame for winches is that of Screw connections required a relatively large amount of assembly work. In addition, the in the end plates of the drive shaft of the cable drum due to the associated mechanical loads on the support frame solidly trained side members, what to heavy weight of the support frame.

Es ist Aufgabe der vorliegenden Erfindung, den Aufwand bei der Montage der Seilwinde zu verringern. Außerdem soll eine deutliche Verringerung des Gewichts der Seilwinde erzielt werden. It is an object of the present invention to increase the effort involved in installing the cable winch reduce. In addition, a significant reduction in the weight of the cable winch is to be achieved become.

Die Lösung dieser Aufgabe ist erfindungsgemäß gekennzeichnet durch die im Patentanspruch 1 angegebenen Merkmale. Durch die kennzeichnenden Merkmale der Unteransprüche 2 bis 13 ist der Tragrahmen in vorteilhafter Weise weiter ausgestaltbar.The solution to this problem is characterized by the im Claim 1 specified features. Due to the characteristic features of the Subclaims 2 to 13, the support frame can be further configured in an advantageous manner.

Dadurch, daß die Stimelemente mit einem Spannelement, und zwar einer Gewindestange über die Längsträger in deren Längsrichtung gegeneinander verspannbar sind, derart, daß die Enden der Längsträger hierdurch an den Stimelementen zumindest in deren Längsrichtung fixiert sind, wird eine deutliche Verringerung des Aufwandes beim Zusammenbau der Seilwinde erzielt. Die Verwendung eines derartigen Spannelementes zur Verspannung der Stimelemente ermöglicht es darüber hinaus, die Längsträger so auszugestalten, daß eine besonders stabile und verwindungssteife Tragrahmenkonstruktion entsteht. Die Längsträger wirken zwar mit dem Spannelement zusammen, dienen aber bei der erfindungsgemäßen Lösung in erster Linie der Formstabilität des Tragrahmens, insbesondere gegen Verdrehen, so daß als Längsträger beispielsweise beliebige Hohlprofilquerschnittsformen mit hoher Steifigkeit verwendbar sind, ohne Nachteil für die Stabilität des gesamten Rahmens.The fact that the stimulating elements with a clamping element, namely a threaded rod are braced against each other in the longitudinal direction of the longitudinal beams, such that the ends of the side members thereby at least in the stimulation elements Are fixed in the longitudinal direction, a significant reduction in effort Assembly of the winch achieved. The use of such a tensioning element Bracing the stimulation elements also allows the side members to be so to design that a particularly stable and torsion-resistant support frame construction arises. The side members interact with the tensioning element, but they serve the solution according to the invention primarily the dimensional stability of the support frame, especially against twisting, so that, for example, any longitudinal beam Hollow profile cross-sectional shapes with high rigidity can be used without disadvantage for the Stability of the entire frame.

Bei einer besonders einfachen Ausgestaltung der Erfindung ist das Spannelement als Gewindestange mit jeweils mindestens an den Enden mit jeweils mindestens im Bereich der Stangenenden ausgebildetem Außengewinde ausgebildet.In a particularly simple embodiment of the invention, the clamping element is as Threaded rod with at least at the ends, each with at least in the area of Rod ends formed external thread.

Aus Stabilitätsgründen und der Einfachheit wegen sind die Stirnelemente vorzugsweise plattenförmig ausgebildet. Dabei weist eines der beiden Stimelemente eine Aufnahmeöffnung mit Innengewinde auf, die zur Aufnahme des einen Endes der Gewindestange dient; und das andere der beiden Stimelemente ist mit einer Durchtrittsöffnung für die Gewindestange versehen, so daß das über das Stimelement hinausragende Ende der Gewindestange mit einer Mutter versehen werden kann. Durch Anziehen der Mutter, d.h. durch Verschraubung über die Gewindestange, sind die Stimelemente über die zwischengeschalteten Längsträger in Längsträgerrichtung gegeneinander auf einfache Weise verspannbar.For reasons of stability and simplicity, the end elements are preferred plate-shaped. One of the two stimulus elements has one Receiving opening with internal thread, which is used to receive one end of the Threaded rod serves; and the other of the two stimulus elements is with one Provide passage opening for the threaded rod, so that this over the stimulus protruding end of the threaded rod can be provided with a nut. By Tightening the nut, i.e. by screwing on the threaded rod, they are Stim elements via the intermediate longitudinal beams in the longitudinal beam direction easily clamped against each other.

Mit der Erfindung wird vorgeschlagen, daß der Längsträger einen Querschnitt mit U-Profil aufweist, wodurch eine besonders hohe Formstabilität erzielt wird. The invention proposes that the side member has a cross section with a U-profile has, whereby a particularly high dimensional stability is achieved.

Eine einfache Fixierung der Längsträgerenden an den Stirnelementen bei hoher Formstabilität wird durch Vertiefungen erreicht, die zur Form der Längsträgerenden komplementär sind. Eine hohe Formstabilität kann alternativ dazu auch durch auf der Innenseite der Stirnelemente angeordnete Vorsprünge zur Fixierung der Längsträgerenden erzielt werden. Diese Vorsprünge weisen vorteilhafterweise von Vorrichtungsteilen der Stirnelemente gebildete Anschlagflächen auf und/oder die Vorsprünge sind als Nocken ausgebildet.A simple fixation of the longitudinal beam ends to the end elements at high Dimensional stability is achieved by depressions that shape the longitudinal beam ends are complementary. Alternatively, high dimensional stability can also be achieved by using the Projections arranged on the inside of the end elements for fixing the Longitudinal beam ends can be achieved. These projections advantageously point from Device parts of the end elements formed on and / or the stop surfaces Projections are designed as cams.

Eine weitere Vereinfachung des Tragrahmens ohne Verringerung der Formstabilität aber mit Reduzierung des Gewichts läßt sich dadurch erzielen, daß die Seiltrommel über beispielsweise aufgeschobene Lager direkt auf der Gewindestange, die dabei als Drehachse wirksam ist, abgestützt ist. Der Durchtritt einer Antriebswelle wird dabei über einen Durchbruch in mindestens einem der Stirnelemente erzielt. Zum Antrieb der Seiltrommel ist die Antriebswelle zweckmäßigerweise mit einer Außenverzahnung und die Innenseite der zylinderförmigen Außenwand der Seiltrommel mindestens in dem entsprechenden Bereich mit einer Innenverzahnung versehen, in welche die Außenverzahnung der Antriebswelle eingreift.A further simplification of the support frame without reducing the dimensional stability but with a reduction in weight can be achieved in that the rope drum via, for example, slid-on bearings directly on the threaded rod, which as Axis of rotation is effective, is supported. The passage of a drive shaft is thereby achieved through an opening in at least one of the end elements. To drive the Rope drum, the drive shaft is expediently with external teeth and the inside of the cylindrical outer wall of the rope drum at least in the corresponding area with internal teeth into which the External toothing of the drive shaft engages.

Ein Ausführungsbeispiel für einen Tragrahmen ist in Fig. 1 als Längsschnitt dargestellt. Dabei bilden die zwischen den beiden seitlichen Stirnelementen 1,2 in Form von Stirnplatten 1a, 2a, die im wesentlichen parallel mit Abstand zueinander angeordnet sind, mit den quer dazu oben und unten angeordneten Längsträgern 3 den eigentlichen Tragrahmen, innerhalb dessen eine drehbare Seiltrommel 4 über Lager 5 direkt auf einem als Gewindestange 6a ausgebildeten Spannelement 6 abgestützt ist. Wie Fig. 1 erkennen läßt, ist die Gewindestange 6a parallel zu den Längsträgern 3 angeordnet. Die Gewindestange 6a ist an den Enden jeweils mit einem Außengewinde 7 versehen; zur Aufnahme eines Endes der Gewindestange 6a dient eine zentrisch in der Stirnplatte 1 ausgebildete Öffnung 8, die mit einem korrespondierenden Innengewinde 9 versehen ist, so daß das eine Ende der Gewindestange 6a durch Verschraubung fest mit der Stirnplatte 1a verbindbar ist. Das andere Ende der Gewindestange 6a ragt durch eine ebenfalls zentrische Öffnung 10 in der Stirnplatte 2a sich über diese hinaus erstreckend nach außen, so daß mittels einer Mutter 11 eine Verschraubung der Stirnplatten 1a, 2a über die Gewindestange 6a ermöglicht wird. Ein Anziehen der Mutter 11 bewirkt, daß die Stirnplatten 1a, 2a über die Längsträger 3 in Längsträgerrichtung gegeneinander verspannt sind, so daß eine kraftschlüssige Verbindung der Stirnplatten 1a, 2a über die Längsträger 3 erzielt wird.An embodiment of a support frame is shown in Fig. 1 as a longitudinal section. The form between the two side end elements 1, 2 in the form of End plates 1a, 2a, which are arranged substantially parallel to one another at a distance are, with the transversely arranged above and below longitudinal beams 3 den actual supporting frame, within which a rotatable cable drum 4 via bearing 5 is supported directly on a clamping element 6 designed as a threaded rod 6a. As can be seen in FIG. 1, the threaded rod 6a is parallel to the longitudinal beams 3 arranged. The threaded rod 6a has an external thread at the ends 7 provided; for receiving one end of the threaded rod 6a is used centrally in the end plate 1 formed opening 8, which with a corresponding Internal thread 9 is provided so that one end of the threaded rod 6a Screw connection is firmly connected to the end plate 1a. The other end of the Threaded rod 6a protrudes through a likewise central opening 10 in the end plate 2a extending beyond this so that by means of a nut 11 a Screwing the end plates 1a, 2a is made possible via the threaded rod 6a. On Tightening the nut 11 causes the end plates 1 a, 2 a over the side members 3 in Longitudinal direction are braced against each other, so that a non-positive Connection of the end plates 1a, 2a is achieved via the side members 3.

Die auf der Gewindestange 6a über die Lager 5 drehbar abgestützte Seiltrommel 4 wird über eine mit einer Außenverzahnung versehene Antriebswelle 12 angetrieben, die hierzu in eine in die Innenfläche der Seiltrommel 4 in Längsrichtung eingeformte Innenverzahnung eingreift; die Antriebswelle 12 durchdringt die Stirnplatte 1 durch eine hierzu vorgesehene Öffnung.The cable drum 4 rotatably supported on the threaded rod 6a via the bearings 5 is driven by a drive shaft 12 provided with external teeth, which for this purpose is formed in the longitudinal direction in the inner surface of the cable drum 4 Internal toothing engages; the drive shaft 12 penetrates the face plate 1 through a opening provided for this purpose.

Fig. 2 zeigt eine einfache und trotzdem sehr wirkungsvolle Fixierung der Längsträger 3 an der Stirnplatte 1a, 2a; Fig. 3 zeigt einen Teilschnitt entlang der Schnittlinie A-A gemäß Fig. 2. Hierzu ist die Stirnplatte 1a, 2a an den zugehörigen Stellen mit Vorsprüngen versehen. Wie Fig. 3 und Fig. 4 erkennen lassen, ist der an der Kante der Stirnplatte 1a, 2a angeordnete Vorsprung als Anschlagleiste 13 mit quaderförmigem Querschnitt ausgebildet, wobei die Anschlagfläche parallel zur Längsrichtung des Tragrahmens verläuft. Ferner sind parallel zur Anschlagfläche mit Abstand zueinander zwei als Nocken 14 ausgebildete Vorsprünge an der Stirnseite vorgesehen, deren Längsachse ebenfalls parallel zur Längsrichtung des Tragrahmens 7 verläuft. Die Längsträger 3 weisen ein U-Profil auf, das so dimensioniert ist, daß das Ende des Längsträgers 3 - wie in den Figuren gezeigt - jeweils formschlüssig in den von den Nocken 14 und der Anschlagleiste 13 gebildeten Spalt einsetzbar ist. Der Abstand der Nocken 14 ist so gewählt, daß deren Außenflächen die inneren Seitenflächen und die innere Bodenfläche des Längsträgers 3 im eingesetzten Zustand berühren, wodurch eine seitliche Verschiebung des Längsträgers 3 verhindert wird. Selbstverständlich kann die Anschlagleiste 13 ebenfalls als Nocken ausgebildet sein. Wichtig ist lediglich, daß der Längsträger 3 im wesentlichen spielfrei zwischen die Vorsprünge 13, 14 formschlüssig einsetzbar ist.2 shows a simple, yet very effective fixation of the longitudinal beams 3 on the end plate 1a, 2a; Fig. 3 shows a partial section along the section line A-A 2. For this purpose, the end plate 1 a, 2 a is at the associated points Provide protrusions. As can be seen in FIGS. 3 and 4, this is at the edge the end plate 1a, 2a arranged projection as a stop bar 13 with cuboid cross-section, the stop surface parallel to Longitudinal direction of the support frame runs. Furthermore, are parallel to the stop surface Distance from each other two projections designed as cams 14 on the end face provided, the longitudinal axis also parallel to the longitudinal direction of the support frame 7 runs. The longitudinal beams 3 have a U-profile which is dimensioned so that the End of the longitudinal beam 3 - as shown in the figures - in each case in the form gap formed by the cams 14 and the stop bar 13 can be used. The Distance of the cams 14 is chosen so that the outer surfaces of the inner Side surfaces and the inner bottom surface of the longitudinal beam 3 used Touch condition, which prevents a lateral displacement of the side member 3 becomes. Of course, the stop bar 13 can also be designed as a cam his. It is only important that the side member 3 is essentially free of play between the Projections 13, 14 can be used in a form-fitting manner.

In Fig. 4 ist eine andere Variante im Teilschnitt quer durch den Tragrahmen gemäß Fig. 1 dargestellt, mit der eine spielfreie Fixierung der Längsträger 3 gewährleistet wird. Hierzu sind in den Stirnplatten 1a, 2a an den entsprechenden Stellen Vertiefungen in Form von schlitzartigen Ausnehmungen 15 mit U-förmigem Querschnitt ausgebildet und ist die Vertiefung bezüglich ihrer Form zur Form des Längsträgerendes komplementär. Wichtig ist auch bei dieser Ausgestaltungsvariante der Längsträgerfixierung, daß durch Einstecken der Längsträger 3 eine im wesentlichen spielfreie formschlüssige Verbindung zwischen den Stirnplatten 1a, 2a und den Längsträgern 3 herstellbar ist.4 is another variant in partial section across the support frame according to Fig. 1 shown with which a play-free fixation of the side members 3 is guaranteed becomes. For this purpose, in the end plates 1a, 2a at the appropriate points Wells in the form of slot-like recesses 15 with a U-shaped Cross-section is formed and the recess is in shape to the shape of the Complementary. This design variant is also important the side member fixation that by inserting the side member 3 in a essential play-free positive connection between the end plates 1a, 2a and the side members 3 can be produced.
