Description

Die Erfindung betrifft eine Schlauchaufrollvorrichtung für einen Kran-/Bohrgerätewagen.The invention relates to a hose reel-up device for a crane / drill carriage.

Im Hoch- und Tiefbau werden Kran-/Bohrgerätewagen eingesetzt, die über einen meist beweglichen Mast verfügen. Dieser steht mit einem Oberwagen mit Führerhaus in Verbindung, welcher wiederum auf einem Unterwagen angeordnet ist. Der Mast selbst kann z.B. über eine hydraulische Einrichtung und/oder eine Zugseileinrichtung schwenkbar sein und weist an seinem oberen Ende eine Umlenkeinrichtung auf, über die z.B. ein Zugseil und ein Hydraulikschlauch gelenkt werden. Das Zugseil trägt dann ein Bearbeitungswerkzeug, z.B. einen Schlitzwandgreifer, welcher über den Hydraulikschlauch betätigt wird.In building and civil engineering, crane / drilling rig carriages are used, which usually have a movable mast. This is connected to an uppercarriage with a cab, which in turn is arranged on an undercarriage. The mast itself can e.g. be pivotable via a hydraulic device and / or a traction cable device and has a deflection device at its upper end, via which e.g. a pull rope and a hydraulic hose are steered. The pull rope then carries a processing tool, e.g. a diaphragm wall grab, which is operated via the hydraulic hose.

Beim Einsatz eines Schlitzwandgreifers oder eines ähnlichen Bodenbearbeitungsgeräts muß dieses oft sehr tief in einen durch den Schlitzwandgreifer ausgehobenen Schlitzgraben oder dergl. herabgelassen werden. Dies geschieht über das Zugseil, welches wiederum mit einer Seilwinde auf dem Oberwagen oder ähnlichen Einrichtungen verbunden ist.When using a diaphragm wall grab or a similar soil cultivation device, this often has to be lowered very deeply into a trench or the like excavated by the diaphragm wall grab. This happens through the Traction rope, which in turn is connected to a winch on the superstructure or similar devices.

Nachteil einer derartigen Anordnung ist, daß der Hydraulikschlauch z.B. von Hand zugeführt werden muß und ebenso während des Herausziehens des Schlitzwandgreifers wiederum von Hand herausgezogen werden muß.The disadvantage of such an arrangement is that the hydraulic hose e.g. must be fed by hand and must also be pulled out again by hand while pulling out the diaphragm wall gripper.

Aus der DE 4021925 A1 ist eine Kabelaufwickelvorrichtung bekannt, die für elektrische Kabel geeignet ist. Sie weist eine Kabeltrommel auf, die beständig von einer Spiralfeder belastet wird und somit ein Aufwickeln des elektrischen Kabels bewirkt. Eine derartige Anordnung ist jedoch für Hydraulikschläuche ungeeignet, da diese sehr viel schwerer und größer als elektrische Kabel sind und die bekannte Anordnung für derartige Kräfte nicht ausgelegt ist.DE 4021925 A1 discloses a cable winding device which is suitable for electrical cables. It has a cable drum which is constantly loaded by a spiral spring and thus causes the electrical cable to be wound up. However, such an arrangement is unsuitable for hydraulic hoses, since they are much heavier and larger than electrical cables and the known arrangement is not designed for such forces.

Aus der DE 2815024 ist eine Spann- und Arbeitsstreckenausgleichsanordnung für Hydraulikschläuche von Gabelstaplern bekannt. Diese ist jedoch für eine automatische Zu- und Abführung eines Hydraulikschlauchs bei einem Kran-/Bohrgerätewagen ungeeignet.From DE 2815024 a tensioning and working distance compensation arrangement for hydraulic hoses of forklifts is known. However, this is unsuitable for an automatic supply and discharge of a hydraulic hose in a crane / drill truck.

Aufgabe der vorliegenden Erfindung ist es daher, eine automatische Einrichtung zum Zu- und Abführen eines Hydraulikschlauches für ein von einem derartigen Kran-/ Bohrgerätewagen geführtes Bearbeitungswerkzeug anzugeben.The object of the present invention is therefore to provide an automatic device for supplying and removing a hydraulic hose for a processing tool guided by such a crane / drill carriage.

Diese Aufgabe wird dadurch gelöst, daß eine Schlauchaufrollvorrichtung für einen Kran-/Bohrgerätewagen über Befestigungsmittel an einem Mast des Kran-/Bohrgerätewagens befestigt ist und einen auf einer um eine Achse drehbar gelagerten aufwickelbaren Schlauch, sowie eine Wickelrolle aufweist, die mit der Schlauchtrommel drehbar gekoppelt ist und ein Zugseil trägt, welches beim Abwickeln des Schlauches aufgewickelt wird und dabei eine Federeinrichtung vorspannt.This object is achieved in that a hose reel device for a crane / drill carriage is fastened to a mast of the crane / drill carriage by means of fastening means and has a hose which can be wound on an axis which is rotatable about an axis, and a winding roll which is rotatably coupled to the hose drum is and carries a traction rope, which is wound up when the hose is unwound and thereby prestresses a spring device.

Weiterbildungen sind Kennzeichen der Unteransprüche.Further training is characteristic of the subclaims.

Der Grundgedanke der Erfindung ist also darin zu sehen, daß ein Hydraulik- oder auch Pneumatikschlauch beim Abwickeln von seiner Schlauchtrommel gleichzeitig ein Seil auf einer zweiten z.B. parallel zur Schlauchtrommel angeordneten Wikkelrolle aufwickelt und dieses Seil dadurch eine Federeinrichtung vorspannt. Die somit vorgespannte Federeinrichtung zieht dann beim Herausziehen des Bearbeitungswerkzeugs wiederum gleichzeitig automatisch den zuvor herausgezogenen Hydraulikschlauch auf, indem sie sich entspannt.The basic idea of the invention is therefore to be seen in the fact that a hydraulic or pneumatic hose simultaneously unwinds a rope on a second e.g. coiled winding roller arranged parallel to the hose drum and this rope thereby pretensioning a spring device. The spring device thus preloaded then automatically pulls the previously pulled hydraulic hose out again when the processing tool is pulled out, in that it relaxes.

Vorteil der Erfindung ist, daß die Federeinrichtung z.B. aus einer einfachen Schraubenfederanordnung bestehen kann. Diese wiederum kann aus mehreren gestapelten Federn bestehen, die mit unterschiedlichen Federsteifigkeiten versehen sind, um z.B. einen nichtlinearen Verlauf der Zugkraftkennlinie zu erreichen.The advantage of the invention is that the spring device e.g. can consist of a simple coil spring arrangement. This in turn can consist of several stacked springs, which are provided with different spring stiffness, e.g. to achieve a non-linear course of the tractive force characteristic.

Die Federeinrichtung kann zudem anstelle der Schraubenfeder auch vorteilhafterweise mit hydraulischen oder pneumatischen Federn versehen sein.The spring device can also advantageously be provided with hydraulic or pneumatic springs instead of the helical spring.

Um eine Zugbelastung auf den Schlauch bei ausgefahrenem Bearbeitungsgerät, z.B. einem Schlitzwandgreifer, zu vermeiden, kann zusätzlich vorteilhafterweise eine Rastsperre mit einer der Wickelrollen und/oder der Schlauchtrommel gekoppelt sein, welche deaktiviert werden muß, um ein automatisches Aufwickeln des Hydraulikschlauches zu bewirken.To withstand a tensile load on the hose when the processing device is extended, e.g. To avoid a diaphragm wall gripper, a detent can additionally advantageously be coupled to one of the winding rollers and / or the hose drum, which must be deactivated in order to bring about an automatic winding of the hydraulic hose.

In einer weiteren Ausgestaltung kann die Erfindung vorteilhafterweise mit einer Bremse versehen sein, die bei Überschreiten einer vorbestimmten Drehgeschwindigkeit der Wikkelrolle und/oder Schlauchtrommel auf diese einwirkt und z.B. bei einem Bruch des Hydraulikschlauches ein zu schnelles Aufwickeln des Schlauches und damit eine Gefahrensituation verhindert.In a further embodiment, the invention can advantageously be provided with a brake which acts on the winding roller and / or hose reel when a predetermined rotational speed is exceeded and, for example in the event of a break in the hydraulic hose, prevents the hose from being wound up too quickly and thus prevents a dangerous situation.

Die Erfindung wird nachfolgend anhand von zwei Figuren näher erläutert.The invention is explained in more detail below with reference to two figures.

Show it:
Fig. 1:
a partial sectional view of a hose retractor according to the invention, and
Fig. 2:
a crane / drill carriage with the hose reel device according to the invention.

Gemäß Figur 1 ist die Schlauchaufrollvorrichtung z.B. auf einer Auslegertraverse 1 über Befestigungseinrichtungen 2 und 7 befestigt. Die Schlauchaufrollvorrichtung ist in zwei Teile geteilt, einen starren und einen um eine Achse A drehbar gelagerten Teil. Die Befestigungseinrichtung 2 weist zu diesem Zweck ein Lager auf, in dem eine sich seitlich von der Schlauchtrommel 11 für den Hydraulikschlauch 12 in Achsrichtung erstreckende Welle 13 drehbar gelagert wird. In der dargestellten Ausführungsform befindet sich die den Hydraulikschlauch 12 tragende Schlauchtrommel 11 linksseitig von der Befestigungseinrichtung 2 und rechtsseitig ist eine Wickelrolle 5 mit der Welle 13 gekoppelt. Diese dient zur Aufnahme eines Zugseils 6, z.B. eines Stahlseils. Rechtsseitig von der Wickelrolle 5 schließt sich z.B. ein Hydraulikanschlußventil 3 an, welches mit einer in der Welle 13 geführten Hydraulikverbindungsleitung 4 über eine Dichtung (nicht dargestellt) in Verbindung steht. Die Hydraulikverbindungsleitung 4 dient zum Anschluß des auf der Schlauchtrommel 11 aufgerollten Schlauches 12 in Verbindung mit dem Anschlußventil 3 an ein auf dem Oberwagen des Kran-/Bohrgerätewagens befindliches Hydrauliksystem.According to FIG. 1, the hose reel-up device is fastened, for example, on a cantilever traverse 1 via fastening devices 2 and 7. The hose retractor is divided into two parts, a rigid part and a part rotatably mounted about an axis A. For this purpose, the fastening device 2 has a bearing in which a shaft 13 extending laterally from the hose drum 11 for the hydraulic hose 12 is rotatably mounted. In the embodiment shown, the hose drum 11 carrying the hydraulic hose 12 is located on the left-hand side of the fastening device 2 and on the right-hand side a winding roll 5 is coupled to the shaft 13. This serves to receive a pull rope 6, for example a steel rope. To the right of the winding roll 5 there is, for example, a hydraulic connection valve 3, which is connected to a hydraulic connecting line 4 guided in the shaft 13 via a seal (not shown). The hydraulic connecting line 4 is used to connect the hose 12 rolled up on the hose reel 11 in connection with the connection valve 3 to a hydraulic system located on the superstructure of the crane / drill carriage.

An der zweiten Halterung 7 ist ein senkrecht zur Achse A angeordneter Zylinder 8 starr befestigt. Dieser Zylinder 8 weist in seinem Inneren ein Federsystem 10 auf, welches gegen den Boden des Zylinder 8 vorgespannt werden kann. Zu diesem Zweck befindet sich am oberen Ende des Federsystems 10 eine Befestigungsvorrichtung 9 zur Befestigung des Stahlseils 6.A cylinder 8 arranged perpendicular to the axis A is rigidly fastened to the second holder 7. This cylinder 8 has in its interior a spring system 10 which can be biased against the bottom of the cylinder 8. For this purpose, there is a fastening device 9 for fastening the steel cable 6 at the upper end of the spring system 10.

In Figur 2 ist ein gemäß Figur 1 aufgebautes System auf einem Kran-/Bohrgerätwagen 16 installiert dargestellt. Der Kran-/Bohrgerätwagen 16 weist einen Unter- und Oberwagen mit einem Führerhaus auf. Auf dem Oberwagen ist ein beweglicher Ausleger 17 sowie ein zugehöriges bekanntes Auslegerabstützungsystem 18 angeordnet. Am oberen Ende des Auslegers 17 befindet sich eine obere Umlenkung für das das Bearbeitungsgerät tragende Tragseil 19 und den Hydraulikschlauch 12. Am Ende des Tragseils 19 ist z.B. ein Schlitzwandgreifer 15 befestigt, der mit dem Hydraulikschlauch 12 in Verbindung steht und durch das ihn speisende Hydrauliksystem betätigt wird.FIG. 2 shows a system constructed according to FIG. 1 installed on a crane / drill carriage 16. The crane / drill carriage 16 has an undercarriage and superstructure with a driver's cab. A movable boom 17 and an associated known boom support system 18 are arranged on the superstructure. At the upper end of the boom 17 there is an upper deflection for the carrying cable 19 carrying the processing device and the hydraulic hose 12. At the end of the carrying cable 19 is e.g. a diaphragm wall gripper 15 is attached, which is connected to the hydraulic hose 12 and is actuated by the hydraulic system feeding it.

Beim Ablassen des geschlossenen Schlitzwandgreifers 15 in den Schlitzgraben bzw. Boden wird das Tragseil 19 von einer im Oberwagen des Kran-/Bohrgerätwagens 16 befindlichen Wikkelrolle und Antriebsmotor (beide nicht dargestellt) abgerollt. Dadurch bewegt sich der Schlitzwandgreifer 15 in Richtung Boden oder Schlitzgraben. Durch den auch auf den Hydraulikschlauch 12 ausgeübten Zug wird dieser von der Schlauchtrommel 11 abgewickelt. Dadurch wird das Stahlseil 6 auf der mit der Schlauchtrommel 11 gekoppelten Wickelrolle 5 aufgewickelt und dadurch ein Zug auf die Feder 10 im Inneren des Zylinders ausgeübt und diese wird gespannt.When the closed diaphragm wall gripper 15 is lowered into the trench or floor, the supporting cable 19 is unrolled from a winding roller and drive motor (both not shown) located in the superstructure of the crane / drill carriage 16. As a result, the diaphragm wall gripper 15 moves in the direction of the ground or trench. Due to the tension also exerted on the hydraulic hose 12, it is unwound from the hose drum 11. As a result, the steel cable 6 is wound on the winding roller 5 coupled to the hose drum 11 and, as a result, a tension is exerted on the spring 10 in the interior of the cylinder and the latter is tensioned.

Zum Aufziehen des Schlitzwandgreifers 15 wird das Tragseil 19 wieder durch den Antriebsmotor auf die zugehörige (nicht dargestellte) Wickelrolle aufgerollt und dadurch der Schlitzwandgreifer 15 aus dem Schlitzgraben herausbewegt. Die Feder 10 übt nun durch die zuvor gespeicherte Federkraft eine Zugkraft auf das Stahlseil 6 aus und wickelt dieses zuvor das auf die Schlauchtrommel 5 aufgewickelte Stahlseil 6 von dieser ab. Dadurch wird ebenfalls die mit dieser Wikkelrolle 5 gekoppelte Schlauchtrommel 11 in deren Aufwikkelrichtung gedreht und der zuvor abgelassene Hydraulikschlauch 12 automatisch aufgewickelt.To pull up the diaphragm wall gripper 15, the support cable 19 is again rolled up by the drive motor onto the associated winding roller (not shown) and the diaphragm wall gripper 15 is thereby moved out of the trench. The spring 10 now exerts a tensile force on the steel cable 6 by the previously stored spring force and previously coils the steel cable 6 wound on the hose drum 5 from the latter. As a result, the hose drum 11 coupled to this winding roller 5 is also rotated in its winding direction, and the previously drained hydraulic hose 12 is automatically wound up.

Die gesamte Vorrichtung kann zudem mit einer Rastsperre (nicht dargestellt) versehen sein, die nur ein Abwickeln des Hydraulikschlauchs erlaubt und erst bei einer mechanischen Entrastung das automatische Aufwickeln des Hydraulikschlauchs freigibt. Dadurch kann eine Zugentlastung des Hydraulikschlauchs während der eigentlichen Grabarbeiten gewährleistet werden. Die Entriegelung kann dabei jedesmal automatisch, z.B. pneumatisch oder elektrisch erfolgen, wenn der Schlitzwandgreifer aus dem Schlitzgraben gezogen wird. Im einfachsten Fall kann diese Rastsperre aus einem mit der Wickelrolle 5 bzw. der Schlauchtrommel 11 gekoppelten Zahnrad und einer in diese eingreifenden Raste bestehen.The entire device can also be provided with a detent (not shown) which only allows the hydraulic hose to be unwound and only releases the automatic winding of the hydraulic hose when it is released mechanically. This ensures strain relief for the hydraulic hose during the actual digging work. The unlocking can be automatic every time, e.g. pneumatically or electrically when the diaphragm wall grab is pulled out of the trench. In the simplest case, this detent can consist of a gearwheel coupled to the winding roller 5 or the hose drum 11 and a detent engaging in it.

Des weiteren kann aus Sicherheitsgründen noch eine Bremseinrichtung (ebenfalls nicht dargestellt) vorgesehen werden, die z.B. über eine Fliehkraftsteuerung aktiviert werden kann. Diese verhindert, daß im Falle eines Abreißens des Hydraulikschlauches ein unkontrolliertes Aufrollen des restlichen Schlauches erfolgt und dabei eine Gefahrensituation entsteht. Selbstverständlich kann als Bremse die oben erwähnte Rasteinrichtung mitverwendet werden.Furthermore, for safety reasons, a braking device (also not shown) can be provided, which can be activated, for example, via a centrifugal control. This prevents an uncontrolled rolling up of the rest of the hose in the event of the hydraulic hose tearing off, thereby creating a dangerous situation. Of course, the above-mentioned locking device can also be used as a brake.

Anstelle eines Hydraulikschlauchs kann selbstverständlich auch ein Pneumatikschlauch verwendet werden.Instead of a hydraulic hose, a pneumatic hose can of course also be used.

Die Länge der Zylinder 8 kann z.B. je nach Anwendung und Länge des Auslegers 17 bis zu 6 m betragen. Als Hydraulikschlauch eignet sich ein Schlauch mit einem Volumen von ungefähr 2 l/m und mehr, wobei das Schlauchgewicht leer ca. 3,5 kg/m beträgt. Bei einem Schlauchdurchmesser von beispielsweise 50 cm beträgt bei 8 Wicklungen die gespeicherte Schlauchlänge ungefähr 36m.The length of the cylinders 8 can e.g. depending on the application and length of the boom 17 up to 6 m. A hose with a volume of approximately 2 l / m and more is suitable as the hydraulic hose, the empty hose weight being approximately 3.5 kg / m. With a hose diameter of 50 cm, for example, with 8 windings, the stored hose length is approximately 36 m.
