Abstract

A quick connection device for connecting leads, e.g. flexible hydraulic tubes, where the one lead goes, for example, to a hydraulic fluid source or pump, and the other goes to a work place, for example, to a tool, is constructed so that the quick connection device has its one part (2-7) fixed and its other part (11, 12, 13, 14, 15) movable between a disconnected and a connected position. These parts are fitted with complementary coupling components (7,14), which during the connection operation are brought in contact with each other to make a fluid tight connection of the two leads to each other. The fixed part (2-7) has a mounting (3,4) and a bracket (5) for the quick connection component (7), and the movable part has controllable moving components (11,12,13,14,15) including a control device (11), and fixed on this are brackets (15,16) for its part of the quick connection device (14)<IMAGE>

Description

8107174-8 tvärgående tvärstag 4- samt monteringsfästen 5 för redskapets hydraulslarxgars 6 ändkopplirxgar 7, vilka är av han-typ. 8107174-8 transverse crossbars 4 and mounting brackets 5 for the implement hydraulic shears 6 end coupling shafts 7, which are of the male type.

På maskinen 1 monteras på lämpligt ställe den andra 'huvuddelen ex vis medelst de visade monteringsblecken 8, vilka fästes ex vis med hjälp av monteringsbultar 9 vid maskinen. Mellan de båda monteringsblecken 8 sträcker sig styrningar 10 i form av axlar, på vilka rörliga hylsor 11 är anordnade. Hylsorna ll är parvis sammankopplade medelst stag 12. Hylsorna 11 och stagen 12 utgör parvis en rörlig enhet, vid vilken maskinens hydraulledxuingars 13 ändpartier mynnar i ändkopplirigar 14 av hola-typ. Dessa ändkopplirxgar är monterade i ett monteringsparti 15, som är fast.vid de rörliga eraheterna genom monteringsstag 16.The second main part is mounted on the machine 1 in a suitable place, for example by means of the mounting plates 8 shown, which are fastened, for example, by means of mounting bolts 9 to the machine. Between the two mounting plates 8 extend guides 10 in the form of shafts, on which movable sleeves 11 are arranged. The sleeves 11 are connected in pairs by means of struts 12. The sleeves 11 and the struts 12 form a movable unit in pairs, in which the end portions of the machine's hydraulic joints 13 open into hollow-type end couplings 14. These end couplings are mounted in a mounting portion 15 which is fixed to the movable members by mounting rods 16.

En dubbelverkande hydraulcylinder 17 är anordnad för manövrering av de båda rörliga enheterna, som alltså innefattar hylsoma 11, tvärstaget 12, mcnteringspartiet 15 och honkogplingeri 14.A double-acting hydraulic cylinder 17 is provided for actuating the two movable units, which thus comprise the sleeves 11, the cross bar 12, the mounting portion 15 and the female plunger 14.

Hydraulcylindern 17 är monterad vid den ena, på figuren vänstra, rörliga enheten (vid 18), och dess utgående kolvstång 20 har sitt fria ändparti monterat vid den andra rörliga enheten. Hydraulcylirxdern 17 drives av 'ziydraulvätskm som tillfóres genom üllförselslangar 19, och på axlarna 10 finnes lämpligen (icke visade) låsrirxgar för styrning av hydraulcylinderns 17 arbetsoperation. Tillﬁrselslangarna 19 mcnteras till maskinens befintliga hydraulsystem, lämpligen den kreæ som går till redskapshållare för låsning av redskap, och man får då en samtidig arbetsoperaticn för låsning av redskap och ihopkoppling av hydraulslangar.The hydraulic cylinder 17 is mounted at one, in the figure left, the movable unit (at 18), and its output piston rod 20 has its free end portion mounted at the other movable unit. The hydraulic cylinder 17 is driven by hydraulic fluid supplied through supply hoses 19, and on the shafts 10 there are suitably (not shown) locking rings for controlling the operation of the hydraulic cylinder 17. The supply hoses 19 are mounted to the machine's existing hydraulic system, suitably the crane that goes to the tool holder for locking the tool, and you then get a simultaneous work operator for locking the tool and connecting the hydraulic hoses.

Fig l visar uppfinningen klar för användning. Maskinen, som sedan tidigare är försedd med sin utrustning, placeras så att redskapeft med sin anslutningsdel befinner sig i det visade läget. För att koppla ihop redskapets hydraulslangar med maskinens behöver nu föraren (eller den person som skall utföra denna uppgift) aktivera styrutrustningen så att hydraulvätska till föres genom tillñrselslangarna 19 till “rrydraulcylinder 17, som därvid aktiveras så att dess hydraulkolvstång 20 ﬁires ut åt sidan och därvid bringar de båda rörliga enheterna åt sidan, varigenom snabbkopplingsarxslutrﬁngarna 14 förflyttas från sina i fig 1 visade lägen till sina i fig 2 visade hopkoælingslägen. 8107174-8 Fig 2 illustrerar uppfinningen i dess hopkopplade tillstånd.Fig. 1 shows the invention ready for use. The machine, which is already equipped with its equipment, is placed so that the implement shaft with its connecting part is in the position shown. In order to connect the hydraulic hoses of the implement to the machine, the operator (or the person performing this task) now needs to activate the control equipment so that hydraulic fluid is supplied through the supply hoses 19 to the rrydraul cylinder 17, which is activated so that its hydraulic piston rod 20 ﬁ is ejected to the side and brings the two movable units aside, whereby the quick coupling shaft ends 14 are moved from their positions shown in Fig. 1 to their cooling positions shown in Fig. 2. 8107174-8 Fig. 2 illustrates the invention in its interconnected state.

Det framgår att anslutningarna 7 och 14 är sammanförda så att maskinens hydraulslangar 13 nu är sammankopplade med redskapets slangar 6. Detta 'har skett ett snabbt och tillförlitligt sätt, och när anslutningarna 7 och 14 blivit sammanförda träder en mekanisk låsning (icke visad) i anslutningen 14 i funktion. Denna låsning består ända tills styr-utrustningen anställts, så att hydraulcylinderns 17 kolv 20 bringas att röra sig inåt i cylindern 17 för särkoppling av anslutningarna 7 och 14 från varandra. Därvid kommer tvärstagexx 12 att medbriixgas i den inåtriktade rörelsen och anslutningarna 14 föres bort från reaskapets afslumingar 7. Hyaraulforbinaelsen mellan naskin och redskap är därefter avbruten och maskinen kan anvàrxdas för annat ändamål eller kopplas till ett annat redskap.It can be seen that the connections 7 and 14 are connected so that the hydraulic hoses 13 of the machine are now connected to the hose 6 of the implement. This has been done in a fast and reliable manner, and when the connections 7 and 14 have been connected a mechanical locking (not shown) enters the connection 14 in operation. This locking lasts until the control equipment is engaged, so that the piston 20 of the hydraulic cylinder 17 is caused to move inwards in the cylinder 17 for disconnecting the connections 7 and 14 from each other. In this case, the crossbar 12 will be entrained in the inward movement and the connections 14 will be moved away from the locks 7 of the implement. The hyaraul connection between machine and implement is then interrupted and the machine can be used for another purpose or connected to another implement.

Fackmanxxen inom området inser att uppfinningen som här visats och beskrivits med hänvisning till en f.n. föredragen utföringsform kan modifieras och varieras inom ramm för uppfinningens gnmdtarﬂce, sådan den definieras i de bifogade patentkraven, som bestämmer uppfinningens Skyddsområde. Exempelvis kan man använda sig av vid maskinen fast nmterade, dubbla hyaraulcylirnrar 17, armranaae så att deras utgående kolvstänger förflyttar var sin av de rörliga enheterna.Those skilled in the art will recognize that the invention shown and described herein with reference to a present invention. preferred embodiment may be modified and varied within the scope of the invention, as defined in the appended claims, which define the scope of the invention. For example, it is possible to use double-mounted, double hyaraulcylners 17, armranaae so that their output piston rods move each of the movable units.

Fackmannen inser att dessa dubbla hydraulcylindrar i sådant fall _ lämpligen är sammansatta antingen sià vid sida, vända åt var sitt håll, eller i linje med arandra, så att säga “rygg mot rygg".Those skilled in the art will appreciate that in such a case these double hydraulic cylinders are suitably assembled either side by side, facing each other, or in line with each other, so to speak "back to back".
