Description

Die Erfindung betrifft ein Hebezeug, insbesondere einen Seilzug, mit einem mindestens zwei Grundplatten aufweisenden Grundrahmen, mit mindestens zwei ein erstes Trägerende und ein gegenüberliegendes zweites Trägerende aufweisenden Längsträgern, die die Grundplatten miteinander verbinden und voneinander beabstanden.The invention relates to a hoist, in particular a cable, with a base frame having at least two base plates, with at least two longitudinal carriers having a first carrier end and an opposite second carrier end, which interconnect the base plates and spaced from each other.

Aus der deutschen Patentanmeldung DE 43 10 770 A1 ist bereits eine Motorseilwinde für Hubarbeiten im Theater bekannt. Diese Motorseilwinde wird von einem elektrischen Antriebsmotor angetrieben, der über ein Getriebe auf eine Seiltrommel wirkt. Das Getriebe ist zusammen mit zwei Bremsen innerhalb der Seiltrommel angeordnet. Die Seiltrommel ist beidendig in einem Grundrahmen gelagert, der im Wesentlichen aus zwei voneinander beabstandeten und parallel zueinander ausgerichteten Grundplatten besteht. Die Grundplatten haben jeweils eine im Wesentlichen rechteckige Form und sind über vier parallel zur Längsachse der Seiltrommel ausgerichtete Längsträger miteinander befestigt. Die Längsträger sind als Distanzrohre ausgebildet, die jeweils mittels eines innerhalb des Distanzrohres geführten Zugankers und endseitig hieran aufgeschraubten Gewindemuttern mit den Grundplatten in deren Eckbereichen verbunden sind. Die planen Endflächen der Distanzrohre liegen hierbei an den Innenseiten der Grundplatten im Bereich von Durchgangsbohrungen für die Zuganker an.From the German patent application DE 43 10 770 A1 is already known a motor winch for lifting in the theater. This motor winch is driven by an electric drive motor, which acts via a gear on a cable drum. The transmission is arranged together with two brakes within the cable drum. The cable drum is mounted at both ends in a base frame, which consists essentially of two mutually spaced and parallel aligned base plates. The base plates each have a substantially rectangular shape and are fastened to each other via four longitudinal members aligned parallel to the longitudinal axis of the cable drum. The longitudinal members are formed as spacer tubes, which are each connected by means of a guided inside the spacer tube tie rod and end screwed thereto threaded nuts with the base plates in the corner areas. The flat end surfaces of the spacer tubes are in this case on the insides of the base plates in the range of through holes for the tie rods.

Des Weiteren sind in der Beschreibungseinleitung der deutschen Patentanmeldung DE 196 02 927 A1 Hebezeuge, insbesondere elektrische Seilwinden, beschrieben, die modular aus den Baugruppen Elektrik, Motor, Getriebe, Seiltrommel, Tragmittel und Grundrahmen aufgebaut sind. Die einzelnen Baugruppen sind in einer Vielzahl von Kombinationen zusammenbaubar. An dem Grundrahmen sind die Hauptbaugruppen des Hebezeuges befestigt, insbesondere ist dort die Seiltrommel gelagert. Der Grundrahmen besteht mindestens aus zwei Grundplatten, die mit Abstand parallel zueinander angeordnet und über Längsträger miteinander verbunden sind. Je Stirnplatte sind mindestens drei Schraubverbindungen zur Anbindung der Längsträger hieran vorgesehen.Furthermore, in the introduction to the description of the German patent application DE 196 02 927 A1 Hoists, in particular electric winches, described, which are modularly constructed from the modules electrical, motor, gear, cable drum, suspension and base frame. The individual modules can be assembled in a variety of combinations. On the base frame, the main components of the hoist are attached, in particular, there is the cable drum stored. The base frame consists of at least two base plates, which are arranged at a distance parallel to each other and connected to one another via longitudinal members. Per face plate at least three screw connections are provided for connecting the side members thereto.

Die deutsche Patentanmeldung DE 196 02 927 A1 selbst betrifft einen Grundrahmen für Seilwinden, der sich durch einen verringerten Montageaufwand und ein geringeres Gewicht auszeichnen soll. Der Grundrahmen besteht im Wesentlichen aus den beiden Grundplatten, die über einen oberen und einen unteren u-förmigen Längsträger und ein parallel hierzu mit der Drehachse der Seiltrommel zusammen fallendes Zugelement miteinander verbunden sind. Das Zugelement ist aus Vollmaterial, an dessen gegenüberliegenden Enden unter Ausbildung eines Absatzes Gewindeabschnitte angeordnet sind. An einer Seite wird das Zugelement mit seinem Gewindeabschnitt in ein zentral in einer Grundplatte angeordnetes Innengewinde eingeschraubt und liegt mit seinem ringförmigen Absatz über eine Scheibe an der planen Innenseite der Grundplatte an. An der gegenüberliegenden Grundplatte ist zentral eine Durchgangsbohrung vorgesehen, die stufig zur Ausbildung einer ringförmigen Anlagefläche für die Aufnahme des Absatzes des Rohres am Anfang des Gewindestangenabschnittes ausgebildet ist. Der Gewindestangenabschnitt ist durch die Durchgangsbohrung geführt und von außen über eine Gewindemutter mit der Außenseite der Grundplatte verspannt. Hierbei sind die beiden u-förmigen Längsträger in geeignete sacklochartige Aussparungen in den Innenseiten der Grundplatten eingesteckt und werden dort durch die von dem Zugmittel aufgebaute Spannkraft zwischen den Grundplatten gehalten.The German patent application DE 196 02 927 A1 itself relates to a base frame for winches, which should be characterized by a reduced installation costs and a lower weight. The base frame consists essentially of the two base plates, which are connected to each other via an upper and a lower U-shaped side member and a parallel thereto with the axis of rotation of the cable drum falling tension element. The tension member is made of solid material, at the opposite ends to form a shoulder threaded portions are arranged. On one side, the tension element is screwed with its threaded portion in a centrally arranged in a base plate internal thread and is located with its annular shoulder on a disk on the flat inside of the base plate. On the opposite base plate, a through hole is provided centrally, which is formed in stages to form an annular contact surface for receiving the shoulder of the tube at the beginning of the threaded rod portion. The threaded rod portion is guided through the through hole and clamped from the outside via a threaded nut with the outside of the base plate. Here, the two U-shaped side members are inserted into suitable blind hole-like recesses in the inner sides of the base plates and are held there by the tension force established by the traction means between the base plates.

Bei diesen Ausführungsformen nach dem Stand der Technik sind die Verbindungselemente zwischen den Grundplatten als Profile mit Vollrund- oder Rohrquerschnitt ausgebildet, deren Enden in entsprechende Bohrungen oder entsprechend bearbeitete Anlageflächen in den einander zugewandten Flächen der Grundplatten hinein ragen beziehungsweise dort anliegen. Eine Befestigung erfolgt dann über eine Schraubverbindung, die die Profile in deren Längsrichtung mit den Grundplatten verspannen. Diese Verbindungsstellen zwischen den Profilen und den Grundplatten können sowohl Axialkräfte in Richtung der Längsachse der Verbindungselemente bzw. der Seiltrommel als auch sogenannte Eckmomente übertragen. Unter Eckmomenten werden hier Momente verstanden, die beispielsweise durch eine Verwindung des Grundrahmens an den Verbindungsstellen zwischen Grundplatten und Verbindungselementen entstehen. Gleichzeitig wird über die Länge der Profile der exakte Abstand und die Parallelität zwischen den beiden Grundplatten innerhalb der gewünschten Toleranzen hergestellt.In these embodiments according to the prior art, the connecting elements between the base plates are formed as profiles with a circular or tubular cross section, the ends of which project into corresponding bores or correspondingly machined contact surfaces in the mutually facing surfaces of the base plates. An attachment is then via a screw that clamp the profiles in the longitudinal direction of the base plates. These joints between the profiles and the base plates can transmit both axial forces in the direction of the longitudinal axis of the connecting elements or the cable drum and so-called Eckmomente. Corner moments are here understood to mean moments that arise, for example, as a result of a distortion of the base frame at the connection points between base plates and connecting elements. At the same time the exact distance and the parallelism between the two base plates is produced within the desired tolerances over the length of the profiles.

Ferner ist aus dem deutschen Patent DE 10 2005 029 113 B3 ein Grundrahmen eines Hebezeuges bekannt, der wiederum zwei parallele und mit Abstand zueinander angeordnete Grundplatten aufweist. Die Grundplatten sind über Längsträger voneinander beabstandet und lösbar miteinander verbunden. Hierfür tauchen die Enden der Längsträger in Sacklochbohrungen in den zueinander zugewandten Innenseiten der Grundplatten ein und werden darin über Schrauben gegen eine Anlagefläche in den Sacklochbohrungen und somit quer zur Längsrichtung des Längsträgers gedrückt.Furthermore, from the German patent DE 10 2005 029 113 B3 a base frame of a hoist known, in turn, has two parallel and spaced-apart base plates. The base plates are spaced apart by longitudinal members and releasably connected to each other. For this purpose, the ends of the side members dip into blind holes in the mutually facing inner sides of the base plates and are pressed therein by screws against a contact surface in the blind holes and thus transversely to the longitudinal direction of the longitudinal member.

Die US 5 947 450 A beschreibt eine manuelle Seilwinde mit einem Grundrahmen, der aus zwei Grundplatten und rohrförmigen Längsträgern besteht. Die Grundplatten sind über die Längsträger voneinander beabstandet und hierbei über deren einander gegenüberliegenden Enden, die mit ihren Stirnflächen an den Innenseiten der Grundplatten anliegen und sich hieran abstützen, miteinander verbunden. Hierfür ist für jeden Längsträger eine Gewindestange vorgesehen, die durch den entsprechenden Längsträger und in den Grundplatten vorgesehene Durchgangsöffnungen hindurch gesteckt ist. An den einander gegenüberliegenden und an den Außenseiten der Grundplatten heraus ragenden Enden der Gewindestange sind Gewindemuttern aufgeschraubt, wodurch die zwischen den Stirnflächen der Längsträger und den Gewindemuttern angeordneten Grundplatten mit den Längsträgern verspannt werden.The US 5,947,450 A describes a manual winch with a base frame consisting of two base plates and tubular side rails. The base plates are spaced apart from one another via the side members and in this case are connected to one another via their mutually opposite ends, which abut with their end faces on the insides of the base plates and rest thereon. For this purpose, a threaded rod is provided for each longitudinal member, which is inserted through the corresponding longitudinal member and provided in the base plates through openings. At the opposite and on the outer sides of the base plates protruding ends of the threaded rod threaded nuts are screwed, whereby the arranged between the end faces of the longitudinal members and the threaded nuts base plates are clamped to the side rails.

Aus der JP 48 056761 U ist ein vergleichbarer Grundrahmen eines Hebezeugs mit hülsenförmigen Längsträgern und Gewindestangen bekannt. Hierbei sind jeder Gewindestange zwei Längsträger zugeordnet, die sich sowohl an der Innenseite der zugehörigen Grundplatte als auch an zwischen den Grundplatten angeordneten Aufhängeplatten abstützen.From the JP 48 056761 U is a comparable basic frame of a hoist with sleeve-shaped side rails and threaded rods known. Here, each threaded rod two longitudinal members are assigned, which are supported both on the inside of the associated base plate and arranged between the base plates suspension plates.

Aus der FR 2 928 637 A1 ist ein Grundrahmen eines Hebezeugs bekannt, dessen zwei Grundplatten und die sich an den Innenseiten der Grundplatten abstützenden und diese voneinander beabstandenden rohrförmigen Längsträger über Schrauben miteinander verspannt sind.From the FR 2 928 637 A1 is a basic frame of a hoist known, the two base plates and which are supported on the inner sides of the base plates and these spaced apart tubular side members braced by screws.

Die US 2009/308826 A1 offenbart einen Grundrahmen eines Hebezeugs, dessen rohrförmige Längsträger mit zwei Grundplatten mittels rohrschellenartiger Halteelemente verspannt sind. Hierbei sind die Längsträger durch in Eckbereichen der Grundplatten befestigte Halteelemente hindurch gesteckt und über quer zur Längsachse des Längsträgers wirkende Schrauben festgeklemmt.The US 2009/308826 A1 discloses a base frame of a hoist whose tubular side members are braced with two base plates by means of clamp-like retaining elements. Here, the side members are inserted through fixed in corner regions of the base plates holding elements and clamped across transverse to the longitudinal axis of the longitudinal member acting screws.

Die zuvor als Grundplatten bezeichneten Bauelemente des Hebezeugs können auch Gehäuseteile sein, die verschiedene Funktionen des Hebezeuges erfüllen. Beispielsweise dienen diese zur Befestigung des Hubantriebes, zur Lagerung der Seiltrommel, zum Anbau von Traversen für Teile der Seileinscherung, zur Aufnahme der elektrischen Ausrüstung, zur Fußbefestigung des Hebezeuges oder zur Anbringung von Fahrwerksteilen.The previously referred to as base plates components of the hoist may also be housing parts that fulfill various functions of the hoist. For example, these serve for fastening the lifting drive, for storing the cable drum, for mounting trusses for parts of the cable shearing, for receiving the electrical equipment, for foot mounting the hoist or for attaching suspension parts.

Hieraus ergibt sich, dass die Gewindemuttern oder -schrauben zur Befestigung der Längsträger mit dem Grundplatten oft schlecht zugänglich beispielsweise im Gehäuseinneren angeordnet sind. Auch müssen diese Verbindungsstellen häufig aus dem Gehäuse heraus verlagert werden, um eine Zugänglichkeit zu erreichen. Hierdurch wird eine Montage erschwert und die Gehäuse in Form der Grundplatten müssen unnötig vergrößert werden.It follows that the threaded nuts or screws for mounting the side members with the base plates are often poorly accessible, for example, arranged inside the housing. Also, these joints must often be shifted out of the housing to achieve accessibility. As a result, assembly is difficult and the housing in the form of the base plates must be increased unnecessarily.

Die Figur 1 zeigt eine perspektivische Ansicht eines erfindungsgemäßen Seilzuges 1 einer Hebevorrichtung mit einer Seiltrommel 2, die in einem Grundrahmen 3 beidendig gelagert ist.The FIG. 1 shows a perspective view of a cable according to the invention 1 a lifting device with a cable drum 2, which is mounted at both ends in a base frame 3.

Der insgesamt quaderförmige Grundrahmen 3 besteht zu einem Teil aus einer ersten Grundplatte 4a und einer zweiten Grundplatte 4b, an deren einander zugewandten ersten und zweiten Innenseiten 4c und 4d die Seiltrommel 2 gelagert ist. Die Seiltrommel 2 ist um eine Drehachse D drehbar und wird von einem Elektromotor 2a über ein Getriebe 2b angetrieben. Die erste Grundplatte 4a und die zweite Grundplatte 4b sind jeweils quaderförmig beziehungsweise rechteckförmig ausgebildet.The overall cuboidal base frame 3 consists in part of a first base plate 4a and a second base plate 4b, at the mutually facing first and second inner sides 4c and 4d, the cable drum 2 is mounted. The cable drum 2 is rotatable about a rotation axis D and is driven by an electric motor 2a via a transmission 2b. The first base plate 4a and the second base plate 4b are each formed cuboid or rectangular.

Zu einem anderen Teil besteht der quaderförmige Grundrahmen 3 aus mehreren bis zu maximal vier Längsträgern, von denen in der Figur 1 ein erster Längsträger 5a, ein zweiter Längsträger 5b und ein dritter Längsträger 5c sichtbar sind. Über die Längsträger 5a, 5b, 5c werden die Grundplatten 4a, 4b voneinander beabstandet und miteinander verbunden. Hierbei sind die Längsträger 5a, 5b, 5c in den Ecken eines gedachten Vierecks in der ersten und zweiten Grundplatte 4a, 4b angeordnet. Bei der zweiten Grundplatte 4b sind die Längsträger 5a, 5b, 5c in den Eckbereichen der nahezu quadratischen Grundplatte 4b angeordnet. Die erste Grundplatte 4a weist gegenüber der zweiten Grundplatte 4b eine rechteckige Form auf, da diese zur Befestigung des Elektromotors 2a über den dritten Längsträger 5c und den nicht dargestellten möglichen vierten Längsträger hinaus verlängert ist. Entsprechender Weise sind der erste und zweite Längsträger 5a, 5b im Bereich der oberen Eckbereiche der ersten Grundplatte 4a angeordnet und der dritte Längsträger 5c und ein etwaiger vierter Längsträger im Bereich der Mitte und des Seitenrandes der ersten Grundplatte 4a angeordnet. Des Weiteren nimmt diese erste Grundplatte 4a im Bereich ihrer Außenseite 4e das Getriebe 2b auf, das die Seiltrommel 2 antriebsmäßig mit dem Elektromotor 2a verbindet.For another part of the cuboidal base frame 3 consists of several up to a maximum of four longitudinal members, of which in the FIG. 1 a first side member 5a, a second side member 5b and a third side member 5c are visible. About the side members 5a, 5b, 5c, the base plates 4a, 4b are spaced from each other and connected to each other. In this case, the longitudinal members 5a, 5b, 5c are arranged in the corners of an imaginary quadrilateral in the first and second base plates 4a, 4b. In the case of the second base plate 4b, the longitudinal members 5a, 5b, 5c are arranged in the corner regions of the almost square base plate 4b. The first base plate 4 a has a rectangular shape relative to the second base plate 4 b, since this is extended for attachment of the electric motor 2 a via the third longitudinal member 5 c and the possible fourth longitudinal carrier, not shown. Correspondingly, the first and second side members 5a, 5b are arranged in the region of the upper corner regions of the first base plate 4a and the third side member 5c and any fourth side member are arranged in the region of the center and the side edge of the first base plate 4a. Furthermore, this first base plate 4 a receives in the region of its outer side 4 e the gearbox 2 b, which drives the cable drum 2 to drive the electric motor 2 a.

Die Längsträger 5a, 5b sind als Stangen aus Vollmaterial ausgebildet und es sind je nach Einsatzfall des Seilzuges 1 zwei bis vier Längsträger 5a, 5b, 5c vorgesehen, die in ausgewählten oder allen Ecken der Grundplatten 4a, 4b angeordnet sind. Die Längsträger 5a, 5b, 5c haben die Aufgabe die Grundplatten 4a, 4b verwindungssteif miteinander zu verbinden und über die Länge der Längsträger 5a, 5b, 5c wird der gewünschte Abstand und die Parallelität zwischen den beiden Grundplatten 4a, 4b innerhalb der gewünschten Toleranzen erreicht. Im gezeigten Ausführungsbeispiel sind insgesamt drei Längsträger 5a, 5b, 5c vorgesehen, um ein Auf- und Abwickeln eines nicht dargestellten Seils von der Seiltrommel 2 nicht zu behindern. Die Längsträger 5a, 5b, 5c weisen jeweils ein erstes Trägerende 5d und ein gegenüberliegendes zweites Trägerende 5e auf. Die ersten Trägerenden 5d sind jeweils in der ersten Grundplatte 4a und die zweiten Trägerenden 5e jeweils in der zweiten Grundplatte 4b befestigt. Die spezielle Art der Befestigung der ersten Trägerenden 5d in der ersten Grundplatte 4a und der zweiten Trägerenden 5e in der zweiten Grundplatte 4b wird im Zusammenhang mit den Figuren 3 und 4 erläutert.The side members 5a, 5b are formed as rods of solid material and it is ever after use of the cable 1 two to four longitudinal beams 5a, 5b, 5c provided, which are arranged in selected or all corners of the base plates 4a, 4b. The longitudinal members 5a, 5b, 5c have the task of connecting the base plates 4a, 4b torsionally rigid with each other and over the length of the side members 5a, 5b, 5c, the desired distance and the parallelism between the two base plates 4a, 4b achieved within the desired tolerances. In the illustrated embodiment, a total of three longitudinal beams 5a, 5b, 5c are provided in order not to hinder a winding and unwinding of a rope, not shown, of the cable drum 2. The longitudinal members 5a, 5b, 5c each have a first carrier end 5d and an opposite second carrier end 5e. The first carrier ends 5d are respectively fixed in the first base plate 4a and the second carrier ends 5e are respectively fixed in the second base plate 4b. The specific manner of fastening the first carrier ends 5d in the first base plate 4a and the second carrier ends 5e in the second base plate 4b is described in connection with FIGS Figures 3 and 4 explained.

Die Figur 1 zeigt den Seilzug in einem sogenannten Betriebszustand, also nach einer erfolgten Montage der Längsträger 5a, 5b, 5c. In diesem Betriebszustand sind die Längsträger 5a, 5b, 5c mit ihren Längsachsen L parallel und seitlich versetzt zu der Drehachse D der Seiltrommel 2 ausgerichtet.The FIG. 1 shows the cable in a so-called operating condition, so after a successful assembly of the side members 5a, 5b, 5c. In this operating state, the longitudinal members 5a, 5b, 5c with their longitudinal axes L parallel and laterally offset from the axis of rotation D of the cable drum 2 are aligned.

In der Figur 1 ist ein Seilzug 1 mit einem erfindungsgemäßen Grundrahmen 2 dargestellt. Ein derartiger Seilzug 1 kann als Basishebezeug Bestandteil eines Baukastensystems sein und durch Anbauelemente 18 in unterschiedlicher Weise verwendet werden. Als sogenannter Fußzug - wie in Figur 1 gezeigt - kann dieser an einem ortsfesten Bauteil befestigt werden. Hierfür werden entsprechende Anschlusselemente 18 an den Grundplatten 4a, 4b befestigt. Auch kann dieser Seilzug 1 Bestandteil einer Krankatze werden, in dem Fahnrverkskomponenten an den Grundplatten 4a, 4b befestigt werden. Als mögliche Krankatzenbauformen sind eine Unterflanschkrankatze, eine Einschienenkrankatze mit Anordnung des Seilzuges 1 neben der Schiene und eine Zweischienenkrankatze denkbar.In the FIG. 1 a cable 1 is shown with a base frame 2 according to the invention. Such a cable 1 can be as Basishebzeug part of a modular system and used by attachments 18 in different ways. As so-called Fußzug - as in FIG. 1 shown - this can be attached to a stationary component. For this purpose, corresponding connection elements 18 are fastened to the base plates 4a, 4b. Also, this cable 1 can be part of a trolley, are mounted in the Fahnrverkskomponenten to the base plates 4a, 4b. As a possible crane catfish designs a Unterflanschkrankatze, a Einschienenkrankatze with arrangement of the cable 1 next to the rail and a two-rail system are conceivable.

Entsprechender Weise haben die Grundplatten 4a, 4b neben der Lagerung der Seiltrommel 2 verschiedene weitere Funktionen wie beispielsweise den Elektroantrieb 2a zu tragen, Anbautraversen für Teile einer Seileinscherung aufzunehmen, elektrische Ausrüstung zu beherbergen, eine Fußbefestigung des Seilzuges zu ermöglichen oder Fahrwerksteile anzubringen.Correspondingly, in addition to supporting the cable drum 2, the base plates 4a, 4b have to carry various other functions, such as the electric drive 2a, to accommodate attachment ropes for parts of a cable shearing, to house electrical equipment, to attach the cable to the foot allow or mount suspension parts.

Die Figur 2 zeigt eine Draufsicht auf den Seilzug gemäß Figur 1, wobei aus Gründen der Übersichtlichkeit die Seiltrommel 2, das Getriebe 2b und der Elektromotor 2a nicht dargestellt sind. Es ist ersichtlich, dass die beiden Grundplatten 4a, 4b an sich als Gussteile hergestellt sind und aus Gewichtsersparnisgründen einen nach außen offene topfförmige Gestalt mit einem ersten beziehungsweise zweiten Hohlraum 4g, 4h haben, in die Antriebs- oder Elektronikkomponenten des Seilzuges 1 untergebracht werden können. Wie zuvor ausgeführt befindet sich in dem ersten Hohlraum 4e die Verzahnungsteile des Getriebes 2b. Je nach Bedarf und Bauweise können die ersten und zweiten Hohlräume 4e, 4f mit einem Deckel verschlossen werden oder offen bleiben. Der erste Hohlraum 4e in der ersten Grundplatte 4a ist über einen ersten Deckel 6a verschlossen, der über ein rahmenförmiges Halteelement 7 an einer ersten Außenseite 4g der ersten Grundplatte 4a befestigt ist. Der zweite Hohlraum 4f in der zweiten Grundplatte 4b ist über einen zweiten Deckel 6b verschlossen, der direkt über ein rahmenförmiges Halteelement 7 an einer zweiten Außenseite 4h der zweiten Grundplatte 4b befestigt ist. Dieses Haltelement 7 kann auch quergeteilt, d.h. zweiteilig sein, um bei einem Auswechseln der Tragstangen 5a, 5b, 5c einen Teil der Tragstangen 5a, 5b, 5c in einem befestigten Zustand zu belassen, um dem Basishebezeug eine Grundstabilität zu belassen.The FIG. 2 shows a plan view of the cable according to FIG. 1 , wherein for reasons of clarity, the cable drum 2, the gear 2b and the electric motor 2a are not shown. It can be seen that the two base plates 4 a, 4 b are made as castings and weight saving reasons have an outwardly open cup-shaped shape with a first and second cavity 4 g, 4 h, can be accommodated in the drive or electronic components of the cable 1. As stated above, the toothed parts of the transmission 2b are located in the first cavity 4e. Depending on requirements and design, the first and second cavities 4e, 4f can be closed with a lid or left open. The first cavity 4e in the first base plate 4a is closed by a first cover 6a, which is fastened via a frame-shaped holding element 7 on a first outer side 4g of the first base plate 4a. The second cavity 4f in the second base plate 4b is closed by a second cover 6b, which is fastened directly via a frame-shaped holding element 7 on a second outer side 4h of the second base plate 4b. This holding element 7 can also be transversely divided, that is, in two parts, in order to leave a part of the support rods 5a, 5b, 5c in a fixed state when replacing the support rods 5a, 5b, 5c in order to leave the base lifting equipment in a basic state.

An Hand der Figuren 3 und 4 wird nun die Ausführung der Verbindung zwischen den Trägerenden 5d, 5e und den Grundplatten 4a, 4b näher erläutert.Based on Figures 3 and 4 Now, the execution of the connection between the support ends 5d, 5e and the base plates 4a, 4b explained in more detail.

Die Figur 3 zeigt eine Ausschnittsvergrößerung von Figur 2 aus dem Bereich der ersten Grundplatte 4a. Wie zuvor zur Figur 1 beschrieben, weist die erste Grundplatte 4a Befestigungsmöglichkeiten für insgesamt vier Längsträger 5a, 5b, 5c oder weniger als vier Längsträger 5a, 5b, 5c an vier verschiedenen Befestigungsorten auf. In der Figur 3 sind die beiden oberen und zwar der erste und der zweite Längsträger 5a, 5b zu erkennen. Um die Längsträger 5a, 5b mit ihrem ersten Trägerende 5d an der ersten Grundplatte 4a zu befestigen, sind in der ersten Grundplatte 4a im Bereich der gewünschten Befestigungsorte Durchgangsöffnungen 8 angeordnet. Da die Längsträger 5a, 5b, 5c als Stangen mit einem runden Querschnitt ausgebildet sind, weisen die Durchgangsöffnungen 8 einen Durchgangsquerschnittsfläche auf, die geringfügig größer ist als die Querschnittsfläche der Längsträger 5a, 5b, 5c. Die Längsträger 5a, 5b, 5c haben somit einen formschlüssigen Kontakt mit der ersten Grundplatte 4a. Die zentrale Durchgangsachse d der Durchgangsöffnung 8 fällt somit mit der Längsachse L der Längsträger 5a, 5b, 5c im Betriebszustand zusammen. Um das erste Trägerende 5d der Längsträger 5a, 5b, 5c in und entgegen der Längsachse L der Längsträger 5a, 5b, 5c festzuhalten, ist am äußeren Ende des ersten Trägerendes 5d der Durchmesser des Längsträger 5a, 5b, 5c unter Ausbildung einer ringförmigen Absatzfläche 5f und eines Zylinderansatzes 5g konzentrisch verjüngt. Des Weiteren ist in dem ersten Trägerende 5a ausgehend von der äußeren Stirnfläche 5h eine zentral in Richtung der Längsachse L der Längsträger 5a, 5b, 5c gerichtete Gewindebohrung 9 mit einem Innengewinde vorgesehen. Die Einstecktiefe des ersten Trägerendes 5a in die Durchgangsöffnung 8 ist so gewählt und somit der Abstand zwischen der ersten und der zweiten Grundplatte 4a, 4b, dass die Absatzfläche 5f mit der Außenseite 4e der ersten Grundplatte 4a fluchtet. Um den Längsträger 5a, 5b, 5c in dieser Position in Richtung der Längsachse L der Längsträger 5a, 5b, 5c gesehen zu halten, ist ein Halteelement 10 mit einer Haltebohrung 10a vorgesehen. Das Halteelement 10 ist als rechteckiger Rahmen mit vier Haltebohrungen 10a für jede der Durchgangsöffnungen 8 in der ersten Grundplatte 4a ausgebildet. Die Tiefe der Haltebohrungen 10a ist so gewählt, dass diese geringfügig länger ist als die Länge des Zylinderansatzes 5g des ersten Trägerendes 5d. Über eine erste Schraube 11, die von außen in die Gewindebohrung 9 eingeschraubt wird, kann somit ein in die Haltebohrung 10a eingesteckter Zylinderansatz 5g in dem Halteelement 10 befestigt werden. Hierbei wird das Halteelement 10 zwischen dem Kopf der ersten Schraube 11 und der Absatzfläche 5f des ersten Trägerendes 5d eingespannt. Zusätzlich ist zwischen dem Kopf der als Zylinderkopfschraube ausgebildeten Schraube 11 und der Außenseite des Halteelementes 10 eine Scheibe 12 angeordnet. Das plattenförmige Halteelement 10 an sich wird über nicht dargestellte Schrauben auf die Außenseite 4g der ersten Grundplatte 4a aufgeschraubt. Außerdem ist der Deckel 6a zum Verschließen des Hohlraums 4g in der ersten Grundplatte 4a von außen auf das Halteelement 10 geschraubt. Dieses Haltelement 10 kann auch quergeteilt, d.h. zweiteilig sein, um bei einem Auswechseln der Tragstangen 5a, 5b, 5c einen Teil der Tragstangen 5a, 5b, 5c in einem befestigten Zustand zu belassen, um dem Basishebezeug eine Grundstabilität zu belassen.The FIG. 3 shows an enlarged detail of FIG. 2 from the area of the first base plate 4a. As before to FIG. 1 described, the first base plate 4a has mounting possibilities for a total of four side members 5a, 5b, 5c or less than four side members 5a, 5b, 5c at four different mounting locations. In the FIG. 3 are the two upper, namely the first and second side members 5a, 5b to recognize. In order to secure the longitudinal members 5a, 5b with their first support end 5d to the first base plate 4a, passage openings 8 are arranged in the first base plate 4a in the region of the desired attachment locations. Since the side members 5a, 5b, 5c are formed as rods with a round cross section, the through holes 8 have a passage cross-sectional area which is slightly larger than the cross-sectional area of the side members 5a, 5b, 5c. The Side members 5a, 5b, 5c thus have a positive contact with the first base plate 4a. The central passage axis d of the passage opening 8 thus coincides with the longitudinal axis L of the longitudinal members 5a, 5b, 5c in the operating state. In order to hold the first carrier end 5d of the side members 5a, 5b, 5c in and against the longitudinal axis L of the side members 5a, 5b, 5c, the diameter of the side member 5a, 5b, 5c at the outer end of the first carrier end 5d is 5f to form an annular shoulder surface 5f and a cylindrical neck 5g concentrically tapered. Furthermore, in the first carrier end 5a, starting from the outer end face 5h, a threaded bore 9 directed centrally in the direction of the longitudinal axis L of the longitudinal members 5a, 5b, 5c is provided with an internal thread. The insertion depth of the first support end 5a into the passage opening 8 is selected and thus the distance between the first and the second base plate 4a, 4b that the shoulder surface 5f is aligned with the outer side 4e of the first base plate 4a. In order to keep the side member 5a, 5b, 5c in this position in the direction of the longitudinal axis L of the side members 5a, 5b, 5c, a holding element 10 with a holding hole 10a is provided. The holding member 10 is formed as a rectangular frame with four retaining holes 10a for each of the through holes 8 in the first base plate 4a. The depth of the retaining holes 10a is chosen so that it is slightly longer than the length of the cylindrical projection 5g of the first support end 5d. By means of a first screw 11, which is screwed into the threaded bore 9 from the outside, a cylindrical projection 5g inserted in the holding bore 10a can thus be fastened in the holding element 10. In this case, the holding element 10 is clamped between the head of the first screw 11 and the shoulder surface 5f of the first carrier end 5d. In addition, a disk 12 is arranged between the head of the screw 11 designed as a cylinder head screw and the outside of the retaining element 10. The plate-shaped retaining element 10 per se is screwed on not shown screws on the outside 4 g of the first base plate 4 a. In addition, the lid 6a for closing the cavity 4g in the first base plate 4a is screwed onto the holding member 10 from the outside. This holding element 10 can also be transversely divided, that is, in two parts, to leave a part of the support rods 5a, 5b, 5c in a fixed state when replacing the support rods 5a, 5b, 5c, to leave the base hoist a basic stability.

Durch die Art der Befestigung der ersten Trägerenden 5d in den Durchgangsöffnungen 8 über die Halteelemente 10 mit der Schraube 11 ist es möglich, nach Entfernen des Halteelementes 10 die Längsträger 5a, 5b, 5c aus der ersten Grundplatte 4a in Richtung deren Längsachse L heraus zu ziehen. Somit ist es möglich, ohne die Seiltrommel 2 zu entfernen, die Position oder Anzahl der Längsträger 5a, 5b, 5c zu verändern.Due to the way the attachment of the first carrier ends 5d in the Through openings 8 via the holding elements 10 with the screw 11, it is possible to remove after removing the holding element 10, the side members 5a, 5b, 5c out of the first base plate 4a in the direction of the longitudinal axis L out. Thus, it is possible, without removing the cable drum 2, to change the position or number of the side members 5a, 5b, 5c.

Des Weiteren ist der Figur 3 zu entnehmen, dass das erste Trägerende 5a der Längsträger 5a, 5b, 5c nicht einteilig ausgebildet ist, sondern eine Aufsteckhülse 13 aufweist, deren Außendurchmesser dem Außendurchmesser der Längsträger 5a, 5b, 5c entspricht. An dem äußeren freien Ende der Aufsteckhülse 13 ist dann der erste Zylinderansatz 5g und die erste Absatzfläche 5f vorgesehen. Um die Aufsteckhülse 13 mit dem Ende des Längsträgers 5a, 5b, 5c zu verbinden, ist an dem Ende des Längsträgers 5a, 5b, 5c ein zweiter Zylinderansatz 5h und eine zweite Absatzfläche 5i vorgesehen, auf die die Aufsteckhülse 13 aufgesetzt ist. Die Gewindebohrung 9 ist in dem Ende des Längsträgers 5a, 5b, 5c vorgesehen. In der Aufsteckhülse 13 befindet sich nur eine durchgehende Bohrung ohne Gewinde. Die aufgesteckte Aufsteckhülse 13 wird über die Schraube 11 an dem Ende des Längsträgers 5a, 5b, 5c befestigt.Furthermore, the FIG. 3 It can be seen that the first carrier end 5a of the longitudinal members 5a, 5b, 5c is not formed in one piece, but has a slip-on sleeve 13 whose outer diameter corresponds to the outer diameter of the longitudinal members 5a, 5b, 5c. At the outer free end of the slip-on sleeve 13, the first cylindrical projection 5g and the first shoulder surface 5f are then provided. In order to connect the slip-on sleeve 13 with the end of the longitudinal member 5a, 5b, 5c, a second cylindrical projection 5h and a second shoulder surface 5i is provided at the end of the longitudinal member 5a, 5b, 5c, onto which the slip-on sleeve 13 is placed. The threaded hole 9 is provided in the end of the longitudinal member 5a, 5b, 5c. In the slip-on sleeve 13 there is only one through hole without thread. The plugged-on sleeve 13 is fastened via the screw 11 at the end of the longitudinal member 5a, 5b, 5c.

In der Figur 4 ist eine Ausschnittsvergrößerung von Figur 2 aus dem Bereich der zweiten Grundplatte 4b gezeigt. Wie die erste Grundplatte 4a weist die zweite Grundplatte 4b Befestigungsmöglichkeiten für insgesamt vier Längsträger 5a, 5b, 5c oder weniger als vier Längsträger 5a, 5b, 5c an vier verschiedenen Befestigungsorten auf. Um die Längsträger 5a, 5b, 5c mit ihrem zweiten Trägerende 5e an der zweiten Grundplatte 4b zu befestigen, sind in der zweiten Grundplatte 4b im Bereich der gewünschten Befestigungsorte stufenlose Sacklochöffnungen 14 angeordnet, deren Querschnittsfläche geringfügig größer ist als die Querschnittsfläche der Längsträger 5a, 5b, 5c. Die Längsträger 5a, 5b, 5c haben somit einen formschlüssigen Kontakt mit der zweiten Grundplatte 4b. Die zentrale Achse e der Sacklochöffnungen 14 fällt mit der Längsachse L der Längsträger 5a, 5b, 5c im Betriebszustand zusammen. Um das zweite Trägerende 5e der Längsträger 5a, 5b, 5c in und entgegen der Längsachse L der Längsträger 5a, 5b, 5c in der Sacklochöffnung 14 festzuhalten, ist am äußeren Ende des ersten Trägerendes 5d der Durchmesser des Längsträger 5a, 5b, 5c unter Ausbildung einer dritten ringförmigen Absatzfläche 5j und eines dritten Zylinderansatzes 5k konzentrisch verjüngt. Des Weiteren ist in dem zweiten Trägerende 5b ausgehend von dessen äußeren Stirnfläche eine zentral eine in Richtung der Längsachse L der Längsträger 5a, 5b, 5c gerichtete Gewindebohrung 15 mit einem Innengewinde vorgesehen. Die Einstecktiefe des zweiten Trägerendes 5e in die Sacklochöffnung 14 ist so gewählt und somit der Abstand zwischen der ersten und der zweiten Grundplatte 4a, 4b, dass die dritte Absatzfläche 5j an der Innenseite 4c der zweiten Grundplatte 4b anliegt. Um den Längsträger 5a, 5b, 5c in dieser Position in Richtung der Längsachse L der Längsträger 5a, 5b, 5c gesehen zu halten, wird von der Außenseite 4f der zweiten Grundplatte 4f eine Schraube 16 durch eine zentral im Boden der Sacklochöffnung 14 mündende Bohrung 17 in die Gewindebohrung 15 des zweites Trägerendes 5e eingeschraubt. Der Kopf der als Sechskantkopfschraube ausgebildeten Schraube 16 ist, stützt sich somit an der Außenseite 4f der zweiten Grundplatte 4b ab.In the FIG. 4 is an excerpt from FIG. 2 from the area of the second base plate 4b. Like the first base plate 4 a, the second base plate 4 b has fastening possibilities for a total of four side members 5 a, 5 b, 5 c or less than four side members 5 a, 5 b, 5 c at four different attachment locations. In order to secure the longitudinal members 5a, 5b, 5c with their second support end 5e to the second base plate 4b, stepless blind holes 14 are arranged in the second base plate 4b in the region of the desired attachment locations whose cross-sectional area is slightly larger than the cross-sectional area of the longitudinal members 5a, 5b , 5c. The longitudinal members 5a, 5b, 5c thus have a positive contact with the second base plate 4b. The central axis e of the blind hole openings 14 coincides with the longitudinal axis L of the longitudinal members 5a, 5b, 5c in the operating state. In order to hold the second carrier end 5e of the side members 5a, 5b, 5c in and against the longitudinal axis L of the side members 5a, 5b, 5c in the blind hole opening 14, the diameter of the side member 5a, 5b, 5c is formed at the outer end of the first carrier end 5d a third annular shoulder surface 5j and a third cylinder shoulder 5k tapered concentrically. Furthermore, in the second carrier end 5b, starting from its outer end face, a central one in Direction of the longitudinal axis L of the longitudinal beams 5a, 5b, 5c directed threaded bore 15 provided with an internal thread. The insertion depth of the second support end 5e into the blind hole opening 14 is selected, and thus the distance between the first and the second base plate 4a, 4b, that the third shoulder surface 5j rests against the inside 4c of the second base plate 4b. In order to keep the side member 5a, 5b, 5c in this position in the direction of the longitudinal axis L of the side members 5a, 5b, 5c, a screw 16 is formed from the outside 4f of the second base plate 4f through a hole 17 opening centrally in the bottom of the blind hole opening 14 screwed into the threaded bore 15 of the second support end 5e. The head of the screw 16 designed as a hexagonal screw is thus supported on the outside 4f of the second base plate 4b.

In dem vorstehenden Ausführungsbeispiel sind die Längsträger 5a, 5b, 5c jeweils als dreiteilig mit äußeren Halteteilen 13a, 13b beschrieben worden. Grundsätzlich können die Längsträger 5a, 5b, 5c auch einteilig ausgebildet sein, um das erfindungsgemäße Ein- und Ausbauen in deren Längsrichtung zu erreichen.In the above embodiment, the side rails 5a, 5b, 5c have each been described in three parts with outer holding parts 13a, 13b. In principle, the longitudinal members 5a, 5b, 5c can also be formed in one piece, in order to achieve the inventive installation and removal in the longitudinal direction.
