Abstract
Description
Die Erfindung betrifft eine Schlauchaufrollvorrichtung für einen Kran-/Bohrgerätewagen.The invention relates to a hose retractor for a crane / drill truck.
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 / drill truck are used which have a mostly movable mast. This is connected to an uppercarriage with a cab, which in turn is arranged on an undercarriage. Of the Mast itself can e.g. via a hydraulic device and / or a pull cable device can be pivoted and has at its upper end a deflection device, via which e.g. a pull rope and a hydraulic hose are steered. The pull rope then carries a processing tool, e.g. one Diaphragm wall grab, which over the hydraulic hose is operated.
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 similar Soil cultivation equipment must often be very deep in one trench excavated by the diaphragm wall grab or the like. This happens through the Traction rope, which in turn with a winch on the superstructure or similar facilities.
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 likewise while pulling out the diaphragm wall grab again must be pulled out by hand.
Aus der DE-A-4021925 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-A-4021925 is a cable winder known, which is suitable for electrical cables. She points a cable drum, which is constantly held by a spiral spring is loaded and thus a winding of the electrical cable causes. However, such an arrangement is for hydraulic hoses unsuitable as this is much heavier and larger than electrical cables and the known arrangement is not designed for such forces.
Aus der DE-A-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-A-2815024 is a span and working distance compensation arrangement for hydraulic hoses of forklifts known. However, this is for an automatic closing and Removal of a hydraulic hose from a crane / drill truck not suitable.
Schließlich ist aus der FR-A-2 438 619 eine Vorrichtung zum automatischen Aufrollen eines flexiblen Schlauches bekannt geworden, die zur Verwendung an Zapfsäulen, insbesondere von Selbstbedienungstankstellen, vorgesehen ist. Diese Vorrichtung weist eine Schlauchtrommel auf, die im Inneren der Zapfsäule drehbar gelagert und als vergleichsweise kleine, kompakte Einheit in der Zapfsäule geschützt untergebracht ist. Neben der Schlauchtrommel ist eine Wickelrolle angeordnet, die mit der Schlauchtrommel drehfest verbunden ist. Auf der Wickelrolle ist ein Zugseil, das durch eine Einrichtung unter Zugspannung steht, in zur Schlauchaufrollrichtung entgegengesetzter Wickelrichtung auf- und abwickelbar. Durch eine von der Einrichtung erzeugte und über das Zugseil auf die Wickelrolle und somit auf die Schlauchtrommel übertragene Zugkraft kann der ausgezogene Schlauch wieder in die Zapfsäule zurückgezogen und auf die Schlauchtrommel aufgewickelt werden. Die Einrichtung zum Aufbringen der Zugkraft weist ein Gegengewicht auf, das mit einer Zugfeder verbunden sein kann. Zwischen der Wickelrolle und dem Gegengewicht ist ein Flaschen- oder Seilzug vorgesehen.Finally, from FR-A-2 438 619 a device for automatic reeling of a flexible hose known become for use on petrol pumps, especially from Self-service filling stations is provided. This device has a hose reel, which inside the Petrol pump rotatably mounted and as a comparatively small, compact unit protected in the pump is. Next to the hose reel there is a winding roll which is non-rotatably connected to the hose drum. On The winding reel is a pull rope that is created by a device is under tension in the opposite direction to the hose reel Winding direction can be wound up and unwound. By one generated by the device and on the pull rope the winding roll and thus transferred to the hose drum The pulled hose can pull back into the Petrol pump withdrawn and wound onto the hose reel become. The device for applying the traction has a counterweight, which is connected to a tension spring can be. Between the winding roll and the counterweight a pulley or cable pull is provided.
Aufgabe der vorliegenden Erfindung ist es, eine automatische Einrichtung zum Zu- und Abführen eines Hydraulikschlauches für ein von einem Kran-/Bohrgerätewagen geführtes Bearbeitungswerkzeug anzugeben.The object of the present invention is an automatic Device for supplying and removing a hydraulic hose for a processing tool guided by a crane / drill carriage specify.
Diese Aufgabe wird erfindungsgemäß durch eine Schlauchaufrollvorrichtung für einen Kran-/Bohrgerätewagen gelöst, die über Befestigungsmittel an einem Ausleger des Kran-/Bohrgerätewagens befestigt ist und einen auf einer um eine Achse drehbar gelagerten Schlauchtrommel aufwickelbaren Hydraulik- oder Pneumatikschlauch zum Betätigen eines Bearbeitungswerkzeuges des Kran-oder Bohrgerätewagens 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 by a hose reel-up solved for a crane / drill truck, the via fasteners on a boom of the crane / drill truck is attached and one on an axis rotatable hose reel hydraulic or Pneumatic hose for operating a processing tool of the crane or drill carriage as well as a winding roll has, which is rotatably coupled to the hose drum is and carries a pull rope, which when unwinding the Hose is wound and a spring device preloaded.
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 when unwinding from his hose reel a rope on one second e.g. winding roll arranged parallel to the hose drum winds up and this rope thereby a spring device preloaded. The spring device thus preloaded then pulls again when pulling out the processing tool at the same time automatically the previously pulled out Hydraulic hose by relaxing.
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 have different spring stiffnesses are e.g. a non-linear course of the tractive force characteristic to reach.
Die Federeinrichtung kann zudem anstelle der Schraubenfeder auch vorteilhafterweise mit hydraulischen oder pneumatischen Federn versehen sein.The spring device can also be used instead of the coil spring also advantageously with hydraulic or pneumatic Feathers.
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 avoid a tensile load on the hose when the processing device is extended, e.g. a diaphragm wall grab to avoid can also advantageously have a detent one of the winding rollers and / or the hose drum coupled be, which must be deactivated to an automatic To wind up 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, if exceeded a predetermined rotation speed of the winding roller and / or hose reel acts on it and e.g. in the event of a break in the hydraulic hose rapid winding of the hose and thus a dangerous situation prevented.

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 Figure 1, the hose reel device is e.g. on
a
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.On the
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.In Figure 2 is a system constructed according to Figure 1 on a
Crane /
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 lowering the closed
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 auf der Wickelrolle 5 aufgewickelte
Stahlseil 6 von dieser ab. Dadurch wird ebenfalls die mit
dieser Wickelrolle 5 gekoppelte Schlauchtrommel 11 in deren
Aufwickelrichtung gedreht und der zuvor abgelassene Hydraulikschlauch
12 automatisch aufgewickelt.To pull the
Die gesamte Vorrichtung kann zudem mit einer Rastsperre
(nicht dargestellt) versehen sein, die nur ein Abwickeln
des Hydraulikschlauche 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 Schleuchtrommel 11 gekoppelten Zahnrad
und einer in diese eingreifenden Raste bestehen.The entire device can also be locked
(not shown) may be provided that only unwinding
of the hydraulic hoses allowed and only with a mechanical
Unlocking the automatic winding of the hydraulic hose
releases. This can relieve the strain on the
Hydraulic hose during the actual digging
can be guaranteed, the unlocking can be done every time
automatically, e.g. done pneumatically or electrically if
the trench wall grab is pulled out of the trench.
In the simplest case, this detent can be made from one with the
Winding roller 5 or the
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, a braking device can also be used for safety reasons (also not shown) are provided, e.g. be activated via a centrifugal force control can. This prevents that in the event of a tear the hydraulic hose an uncontrolled rolling up of the remaining hose and there is a dangerous situation arises. Of course, the top can be used as a brake mentioned locking device can also be used.
Anstelle eines Hydraulikschlauchs kann selbstverständlich auch ein Pneumatikschlauch verwendet werden.Instead of a hydraulic hose, of course a pneumatic hose can 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

die aufeinander gestapelt sind und jeweils gleiche oder
auch unterschiedliche Federsteifigkeiten besitzen.The
Wenn am Ausleger 17 sowohl linksseitig als auch rechtsseitig
jeweils eine Schlauchtrommel 11 angeordnet sind, z.B.
für einen Zuführschlauch und einen Abführschlauch, ist es
besonders vorteilhaft, daß beide Schlauchtrommeln 11 mit
einer gemeinsamen Schlauchaufrollvorrichtung verbunden
sind. Es ist also auch hier eine einzige Wickelrolle mit
zugehörigem Federspeicher ausreichend.If on the
