Description

Die Erfindung betrifft die Verbindung zwischen dem Ausleger eines Schrägaufzuges und einer seiner Versteifung dienenden Auslegerstütze, vorzugsweise einer Seilstütze.The invention relates to the connection between the cantilever of an inclined elevator and a cantilever support serving to reinforce it, preferably a cable support.

Schrägaufzüge finden bevorzugt im Hochbau Verwendung, wo sie dem Transport von Baumaterialien vom ebenerdigen Niveau zu höher gelegenen Stockwerken und umgekehrt dienen. Derartige Schrägaufzüge bestehen in ihrem Grundaufbau aus einem - in aller Regel auf einem Fahrwerk verfahrbaren - Ausleger, der im wesentlichen durch ein Führungsschienenprofil für einen auf diesem Führungsschienenprofil verfahrbaren Wagen, Kübel oder dgl. gebildet ist.Inclined lifts are preferably used in building construction, where they are used to transport building materials from ground level to higher floors and vice versa. The basic structure of such inclined elevators consists of a boom, which can generally be moved on a trolley, which is essentially formed by a guide rail profile for a carriage, bucket or the like which can be moved on this guide rail profile.

Die vorbeschriebenen Ausleger sind üblicherweise teleskopierbar und können so eine erhebliche Länge erreichen. Da zugleich eine leichte Bauweise bei optimaler Beladungsmöglichkeit erwünscht ist, besteht die Notwendigkeit, den Ausleger auszusteifen. Dies geschieht bei bekannten Auslegern dadurch, daß man dem Ausleger in etwa senkrecht von ihm wegweisende Auslegerstützen zuordnet, über deren freie Enden ein Seil gespannt wird, welches endseitig am Ausleger befestigt ist und so als zugbelasteter Gurt den Ausleger gegen Durchbiegung stützt.The booms described above are usually telescopic and can thus reach a considerable length. Since at the same time a light construction with optimal loading possibility is desired, there is a need to stiffen the boom. This is done in known booms by assigning the boom approximately perpendicularly pointing away from him boom supports, over the free ends of which a rope is stretched, which is attached to the end of the boom and thus supports the boom against deflection as a tensioned belt.

Die vorbeschriebenen, der Seilhalterung dienenden Auslegerstützen können ggf. erhebliche Längenabmessungen erreichen. Aus dem vorgenannten Grund bilden sie praktisch sperriges Zubehör zum Ausleger des Schrägaufzuges und werden erst am Einsatzort am Schrägaufzug montiert. Bei den nach dem Std. d. T. bekannten Auslegern bzw. Auslegerstützen erfolgte die Montage in aufwendiger Weise durch Schraubverbindungen oder dgl.; da sich die Verbindungsstellen einige Meter über dem ebenerdigen Niveau befinden, waren hierzu wieder Leitern oder dgl. erforderlich. Die Montage ist deshalb bei den bekannten Auslegerstützen zeitraubend und nur unter erschwerten Bedingungen durchzuführen.The outrigger supports described above, which serve to hold the rope, can possibly reach considerable length dimensions. For the aforementioned reason, they form practically bulky accessories for the inclined elevator boom and are only installed on the inclined elevator at the place of use. After the hour of d. T. known booms or boom supports, the assembly was carried out in a complex manner by screw connections or the like; since the connection points are a few meters above ground level, ladders or the like were again required for this. The assembly is therefore time-consuming in the known boom supports and can only be carried out under difficult conditions.

Die Erfindung hat sich die Aufgabe gestellt, eine Verbindung der eingangs genannten Gattung zu schaffen, bei der die Montage ohne Verwendung irgendwelcher Losteile und ohne Verwendung von Hilfsmitteln wie Leitern oder dgl. in einfachster Weise vom ebenerdigen Niveau her erfolgen kann. Dabei soll sichergestellt sein, daß eine zuverlässige, den Sicherheitsanforderungen entsprechende Verbindung zwischen Ausleger und Auslegerstütze gegeben ist, daß diese Verbindung aber in ebenso einfacher und wenig aufwendiger Weise lösbar ist.The invention has for its object to provide a connection of the type mentioned, in which the assembly can be carried out in a simple manner from the ground level without the use of any loose parts and without the use of tools such as ladders or the like. It should be ensured that there is a reliable connection between the boom and the boom support that meets the safety requirements, but that this connection can be released in an equally simple and inexpensive manner.

Die Erfindung löst die gestellte Aufgabe bei einer Verbindung zwischen dem Ausleger eines Schrägaufzuges und einer Auslegerstütze, vorzugsweise einer Seilstütze dadurch, daß das auslegerseitige Ende der Auslegerstütze mittels einer federbelasteten Sperre in einer Aufnahmetasche des Auslegers des Schrägaufzuges verriegelbar ist. Nach der erfindungsgemäßen Lösung kann das Ende der Auslegerstütze in die Aufnahmetasche eingeschoben werden, rastet in der Riegelstellung selbsttätig ein und ist so verriegelt, daß ein unbeabsichtigtes Lösen vermieden ist.The invention solves the problem with a connection between the boom of an inclined elevator and a boom support, preferably a rope support, in that the end of the boom support on the boom side can be locked in a receiving pocket of the boom of the inclined elevator by means of a spring-loaded lock. According to the solution according to the invention, the end of the boom support can be pushed into the receiving pocket, engages automatically in the locking position and is locked in such a way that unintentional loosening is avoided.

Eine Ausgestaltung der vorbeschriebenen Erfindung ist dadurch gekennzeichnet, daß an der Auslegerstütze einerseits und am Schrägaufzug andererseits durch die federbelastete Sperre in der Riegelstellung gehaltene, ineinandergreifende Vor- bzw. Rücksprünge vorgesehen sind. Sobald diese Vor- bzw. Rücksprünge in der Verriegelungsposition ineinandergreifen, werden sie durch die federbelastete Sperre gegen unbeabsichtigtes Lösen voneinander gesichert.An embodiment of the above-described invention is characterized in that interlocking projections or recesses are provided on the boom support on the one hand and on the inclined elevator on the other hand by the spring-loaded lock in the locking position. As soon as these projections or recesses interlock in the locking position, they are secured against unintentional detachment by the spring-loaded lock.

Die Ausleger von Schrägaufzügen besitzen in aller Regel Versteifungsgurte, die das Führungsschienenprofil zumindest unterseitig und seitlich umgreifen. Nach einer weiteren Ausgestaltung ist deshalb die Aufnahmetasche des Schrägaufzuges zwischen zwei benachbarten, das Führungsschienenprofil des Schrägaufzuges unterseitig und seitlich von außen umgreifenden Versteifungsgurten angeordnet. Die äußere Begrenzung der Aufnahmetasche erfolgt durch wenigstens einen zwei benachbarte Versteifungsgurte verbindenden Querriegel. Dieser Querriegel ist vorteilhaft mit wenigstens einem zum Tascheninneren vorspringenden Rastnocken versehen, welcher in der Riegelstellung in eine korrespondierende Ausnehmung der Auslegerstütze eingreift. Durch diesen Rastnocken wird die Auslegerstütze gegen eine Relativbewegung zwischen Ausleger und Auslegerstütze in Längsrichtung der Auslegerstütze gesichert, d. h. der Rastnocken bzw. die zugeordnete Ausnehmung nehmen das Stützgewicht auf.The brackets of inclined lifts generally have stiffening belts that grip around the guide rail profile at least on the underside and on the side. According to a further embodiment, the receiving pocket of the inclined elevator is therefore arranged between two adjacent stiffening belts which surround the guide rail profile of the inclined elevator on the underside and laterally from the outside. The outer boundary of the receiving pocket is provided by at least one cross bar connecting two adjacent stiffening belts. This crossbar is advantageously provided with at least one locking cam projecting towards the inside of the pocket, which engages in a corresponding recess in the boom support in the locking position. By means of this latching cam, the boom support is secured against a relative movement between the boom and the boom support in the longitudinal direction of the boom support, i. H. the locking cam or the associated recess take up the support weight.

Weiter wird vorgeschlagen, die Auslegerstütze als Rohr auszubilden und dem zwei benachbarte Versteifungsgurte verbindenden Querriegel einen hakenartigen Fortsatz zuzuordnen, mit dem er in der Riegelstellung formschlüssig in die stirnseitige Rohröffnung einfaßt. Hierbei werden zusätzlich sowohl die in Längsrichtung der Rohrstütze wirkenden Stützkräfte aufgenommen als auch ggf. eine Querbewegung der Stütze in der Tasche verhindert.It is also proposed to design the boom support as a tube and to assign a hook-like extension to the cross bar connecting two adjacent stiffening belts, with which it engages in the locking position in the front tube opening in a form-fitting manner. In this case, both the supporting forces acting in the longitudinal direction of the pipe support are absorbed and, if necessary, a transverse movement of the support in the pocket is prevented.

Nach einer besonderen Gestaltung ist die federbelastete Sperre am Schrägaufzug, vorzugsweise am Versteifungsgurt des Schrägaufzuges, derart angeordnet, daß die Sperre beim Einstecken der Auslegerstütze in die Aufnahmetasche gegen den Druck der Feder ausweicht. Nach dem vollständigen Einsteckvorgang und dem Einrasten der korrespondierenden Vor- bzw. Rücksprünge nimmt die Sperre eine Stellung ein, in der sie mit ihrem Halteblech orthogonal gegen die Längsachse der Auslegerstütze, d. h. orthogonal gegen das Rohr der Auslegerstütze, gerichtet ist. Da das Halteblech der Sperre federbelastet ist, wird es in dieser orthogonal zur Längsachse der Auslegerstütze gerichteten Stellung durch ein am Halteblech befestigtes Stützblech gesichert, welches sich seinerseits an dem Versteifungsgurt abstützt.According to a special design, the spring-loaded lock on the inclined elevator, preferably on the stiffening belt of the inclined elevator, is arranged in such a way that the lock dodges against the pressure of the spring when the boom support is inserted into the receiving pocket. After the complete insertion process and the corresponding projections or recesses snap into place, the lock assumes a position in which it holds with its holding plate orthogonally against the longitudinal axis of the boom support, i. H. orthogonally against the tube of the boom support. Since the retaining plate of the lock is spring-loaded, it is secured in this position, which is oriented orthogonally to the longitudinal axis of the boom support, by a supporting plate fastened to the retaining plate, which in turn is supported on the stiffening belt.

Zur besseren «Einfädelung» und zur sicheren Fixierung der Auslegerstütze in der Aufnahmetasche sind am Führungsschienenprofil des Schrägaufzuges und/oder am Versteifungsgurt Führungs- und/oder Stützflächen vorgesehen, die die innere Begrenzung der Aufnahmetasche bilden. Mit der Erfindung wird somit eine einfach herzustellende und zuverlässige Verbindung zwischen Ausleger und Auslegerstütze geschaffen, die ohne Zuhilfenahme weiterer Hilfsmittel durch einfaches Einstecken der Auslegerstütze in die Aufnahmetasche herstellbar ist, wobei eine selbsttätige Verriegelung erfolgt.For better «threading» and for securely fixing the boom support in the receiving pocket, guide rails are attached to the guide rail profile of the inclined lift and / or to the stiffening belt. and / or support surfaces are provided which form the inner boundary of the receiving pocket. The invention thus creates an easy-to-produce and reliable connection between the boom and the boom support, which can be produced by simply inserting the boom support into the receiving pocket without the aid of further aids, with an automatic locking taking place.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below using an exemplary embodiment.

In den beiden Figuren sind gleiche Teile mit gleichen Bezugszeichen versehen worden.In the two figures, identical parts have been provided with the same reference symbols.

Mit 5 ist ein Schrägaufzug bezeichnet, der in einem etwa halbseitigen Querschnitt dargestellt ist. Der Schrägaufzug 5 weist ein der Führung von Wagen oder Kübeln dienendes Führungsschienenprofil 10 auf, das unterseitig von mehreren Versteifungsgurten 11 umgriffen wird, die, in Längsrichtung des Führungsschienenprofils 10 gesehen, nebeneinander angeordnet sind. Die Versteifungsgurte 11 können aus unterschiedlichen Profilen bestehen; sie können im Querschnitt beispielsweise kastenartig, T-förmig oder dgl. ausgebildet sein. Zwischen zwei benachbarten Versteifungsgurten 11 entsteht ein schmaler Zwischenraum, in den ein Rohr als Auslegerstütze 2 mit seinem auslegerseitigen Ende 1 in Pfeilrichtung 17 eingesteckt werden kann.With 5 an inclined elevator is designated, which is shown in an approximately half-sided cross-section. The inclined elevator 5 has a guide rail profile 10 which serves to guide carriages or buckets and which is surrounded on the underside by a plurality of stiffening belts 11 which, viewed in the longitudinal direction of the guide rail profile 10, are arranged next to one another. The stiffening straps 11 can consist of different profiles; in cross section they can be box-shaped, T-shaped or the like, for example. Between two adjacent stiffening belts 11 there is a narrow space into which a tube can be inserted as a boom support 2 with its boom end 1 in the direction of arrow 17.

Aus der Fig. 1 ist eine Sperre 3 ersichtlich, die durch eine Feder 13 am Versteifungsgurt 11 abgestützt ist. Aufgrund der Federkraft ist die Sperre 3 bemüht, sich im Uhrzeigersinn zu drehen. Bei Bewegung der Auslegerstütze 2 in Pfeilrichtung 17 wird die Kraft der Feder 13 überwunden, das Halteblech 14 weicht aus und die Auslegerstütze 2 kann bis in die in Fig. 2 dargestellte Position geschoben werden, wobei während des «Einfädelungsvorganges» die Auslegerstütze 2 an Führungs- und/oder Stützflächen 16 geführt wird. Diese Führungs- und/oder Stützflächen 16 können sowohl am Führungsschienenprofil 10 als auch am Versteifungsgurt 11 angeordnet sein.From Fig. 1, a lock 3 can be seen, which is supported by a spring 13 on the stiffening belt 11. Due to the spring force, the lock 3 tries to turn clockwise. When the boom support 2 moves in the direction of the arrow 17, the force of the spring 13 is overcome, the holding plate 14 dodges and the boom support 2 can be pushed into the position shown in FIG. 2, the boom support 2 on the guide during the «threading process». and / or support surfaces 16 is guided. These guide and / or support surfaces 16 can be arranged both on the guide rail profile 10 and on the stiffening belt 11.

Zwischen den beiden seitlichen Versteifungsgurten 11 ist ein Querriegel 12 angeordnet, der durch Schweißen, Schrauben oder dgl. mit den beiden benachbarten Versteifungsgurten 11 verbunden ist. Der Querriegel 12 weist einerseits einen hakenartigen Fortsatz 7 (s. Fig. 1) und andererseits einen Rastnocken 6 auf. An diesem Rastnocken 6 gleitet während des «Einfädelungsvorganges» die Außenfläche der Auslegerstütze 2 entlang (s. Fig. 1), bis sie ihre Endposition erreicht hat. In der Endposition taucht der Rastnocken 6 in eine Ausnehmung 8 der Auslegerstütze ein; gleichzeitig greift der hakenartige Fortsatz 7 in die Rohröffnung 9 ein, wobei auch im Bereich des hakenartigen Fortsatzes bzw. der Rohröffnung Zentriermittel (nicht dargestellt) vorgesehen sein können, die die Auslegerstütze zusätzlich in der Aufnahmetasche 4 fixieren. Eine weitere Fixierung kann aber dadurch erfolgen, daß sich die Auslegerstütze 2 in der Endposition mit ihrer Kante 18 gegen die äußere Fläche 19 des Führungsschienenprofils anlegt. Die Festlegung und Sicherung sowohl gegen axiale Verschiebung als auch gegen eine quer hierzu gerichtete Verschiebung erfolgt durch das Halteblech 14, welches sich nunmehr - nachdem sich die Auslegerstütze gegen den Querriegel 12 gelegt hat - in einer Position befindet, die in Fig. 2 dargestellt ist und wobei das Halteblech orthogonal zur Längsachse der Stütze gerichtet diese in ihrer Position festlegt. Das Stützblech 15 stützt sich dabei am Versteifungsgurt 11 ab, so daß eine weitere Bewegung der federbelasteten Sperre 3 im Uhrzeigersinn unterbunden ist. Zum Lösen der Verbindung ist es lediglich erforderlich, mittels einer Stange, eines leichten Rohres oder dgl. das Halteblech 14 der federbelasteten Sperre entgegen dem Uhrzeigersinn soweit zurückzudrücken, daß die Auslegerstütze 2 aus ihrer Verriegelungsposition gelöst und aus der Aufnahmetasche herausgezogen werden kann.A cross bar 12 is arranged between the two lateral stiffening belts 11 and is connected to the two adjacent stiffening belts 11 by welding, screwing or the like. The crossbar 12 has on the one hand a hook-like extension 7 (see FIG. 1) and on the other hand a locking cam 6. During the “threading process”, the outer surface of the boom support 2 slides along this latching cam 6 (see FIG. 1) until it has reached its end position. In the end position, the detent cam 6 dips into a recess 8 in the boom support; at the same time the hook-like extension 7 engages in the tube opening 9, centering means (not shown) can also be provided in the region of the hook-like extension or the tube opening, which additionally fix the boom support in the receiving pocket 4. A further fixation can take place, however, in that the cantilever support 2 rests with its edge 18 against the outer surface 19 of the guide rail profile in the end position. The fixing and securing both against axial displacement and against a transverse displacement is carried out by the retaining plate 14, which is now - after the boom support has been placed against the cross bar 12 - in a position which is shown in Fig. 2 and wherein the holding plate orthogonal to the longitudinal axis of the support fixes this in its position. The support plate 15 is supported on the stiffening belt 11, so that a further movement of the spring-loaded lock 3 in the clockwise direction is prevented. To release the connection, it is only necessary to push back the holding plate 14 of the spring-loaded lock counterclockwise by means of a rod, a light tube or the like so that the boom support 2 can be released from its locking position and pulled out of the receiving pocket.
