Definitions

  • the invention describes a locking bolt for power transmission with integrated media couplings.
  • media lines must be connected with which drive media, such as hydraulic oil, gases or electrical power or control signals from the device or carrier device can reach the attached tool or attached device to energize them.
  • the connecting bolts are first fixed non-positively, which means that the tool is statically effectively connected to the carrier device and only then the media lines, after the sleeves or plugs were brought into the correct position to each other, connected to each other, d. H. the male inserted into the female plug.
  • connection elements for the media plug can be damaged during hard construction site use or that can result from water and soil contamination, which make a connection between the corresponding media couplings required after extensive cleaning work by hand of the corresponding media coupling brackets.
  • Another complication arises when between the different uses of power tools such as vibrators, hydraulic grippers, pliers, scissors, etc. also not driven tools are to be grown on the carrier.
  • the coupling elements for the media lines are arranged for reasons of space side of the force transmitting connecting pin. This has the disadvantage that when using simple installation tools have no media lines whose cultivation variations are severely limited.
  • the invention has the object to enable space-saving manner and reducing and simplifying various operations in the cultivation of differentiated tools to a carrier device and at the same time to achieve a higher protective effect of the hydraulic tool connections, regardless of whether the tool to be mounted is driven or whether it's a simple, non-powered tool, like a backhoe.
  • Fig. 1 shows in a vertical section / view of a device according to the invention, wherein an element 14 is arranged on a tool and element 15 on a carrier device. Based on this figure, the recording of the tool is shown in principle.
  • Fig. 2 shows a connecting bolt according to the invention with internals.
  • Fig. 3 shows the frontal view of a connecting bolt according to the invention with media connection plugs, as it is fastened non-positively on a tool.
  • Fig. 4 and Fig. 5 show different embodiments for different cross sections of connecting bolts.
  • Locking bolt system with media coupling for connection of two elements wherein an element 14 has a connecting bolt 1, which has at its end portions accurately fitting power transmission areas 2, 2 ', which engage frictionally in side plates 20, which essentially serve to transmit transverse forces and bending moments, and that between these power transmission areas 2, 2 'in the connecting bolt 1 transversely to the pin axis 3 receiving bores 4 for hydraulic plugs 5, 7 or other media connection plugs are ordered and that at the connecting bolt 1 to be connected to the element 15 a matching to the geometry of the connecting bolt 1 recess 18, 18 'is arranged and that this recess 18, 18' at least partially contact surfaces 1 1, 1 1 ', which to the corresponding contact surfaces 12, 12 'on the connecting pin 1 fit and congruent and thus in the connected state cause a seal of the hydraulic connector 5, 7 or other connectors.
  • FIG. 2 such a connecting pin 1 is shown.
  • the forces are introduced into side plates 20.
  • FIG. 3 an embodiment is shown in which these side plates are attached to a tool 16.
  • To the hydraulic connectors 5 shown here lead hydraulic hoses 6.
  • the hydraulic connector 5 are fitted in holes 4.
  • Fig. 1 it is shown how to imagine the connection of a tool 16 with the device according to the invention.
  • connection of a excavating tool to an excavator is exemplified.
  • a connecting element 15 is arranged, which consists of side plates 21. These two side plates with mounting holes 26 are connected to each other via an intermediate piece 19.
  • a connecting element 14 is attached to the tool 16, which has two side plates 20.
  • a normal bolt 10 according to the prior art and an inventive connecting pin. 1
  • connection of the tool 6 to the carrier device takes place in such a way that first with the opening 28 of the bolt 10 is taken and then around this pin 10, the element 15 via the connecting bolt according to the invention 1 is pivoted.
  • the side plates 21 and the intermediate piece 19 have a special recess 18, 18 '.
  • this recess 18, 18 ' is designed so that contact surfaces 1 1, 1 1' form, at least to partial surfaces 12, 12 'of the surface of the connecting bolt 1 according to the invention fit.
  • the other media connection plugs are, for example, media connection plugs for gaseous media, for power or plug for the transmission of control data.
  • plug-in connections for media consist of male and female plugs.
  • male connector 5 can be arranged either in the connecting bolt 1 according to the invention or in the recess 18, 18 '.
  • FIG. 1 an embodiment is shown in which the male tool 16, an inventive connecting pin 1 with a male hydraulic connector 5, which protrudes from the connecting pin 1.
  • both a positive and a tight connection is made, d. H. when he has reached the position 13, one or more displaceable locking elements 8 is pushed in front of the position of the bolt 13, so that the connection can not solve.
  • locking elements 8 are prior art devices used to prevent bolts from falling out. These locking elements 8 are specially shaped square steels or cylindrically shaped steels with special flats in the contact area, which can be advanced by means of hydraulic cylinders 9 in the inlet space of the bolt.
  • the connecting bolt 1 according to the invention has a cylindrical shape with a circular cross-section. This form is preferably chosen because it is possible to use tools with media connection lines as well as tools without such media connection lines without conversion measures.
  • the advantage of the device according to the invention lies in the fact that for the production of a media line connection no additional space on the tool or carrier device is required and that even with the use of attachments that do not require media line connections, a simple connection can be made, which ensures that in the unneeded hydraulic connector or connecting elements for other media dirt can occur. No additional handles or additional parts, such as cover elements or "dummies" have to be used.

Abstract

L'invention concerne un système d'axe de verrouillage à raccordement de fluide ou autres, destiné à assembler deux éléments, un desdits éléments comportant un axe de liaison dont les extrémités présentent des zones de transmission de force étroitement ajustées qui coopèrent par friction avec des pièces réceptrices latérales, servant principalement transmettre des efforts de cisaillement et des moments de flexion. Entre ces zones de transmission de force de l'axe de liaison, des ouvertures réceptrices pour des connecteurs hydrauliques ou d'autres connecteurs de raccordement de fluide ou autres sont disposées perpendiculairement à la direction longitudinale de l'axe. Un logement étroitement ajusté à la géométrie de l'axe de liaison est ménagé sur l'élément destiné à être assembler au moyen de l'axe de liaison. Ce logement présente au moins localement des surfaces de contact qui correspondent par ajustement serré et congruence aux surfaces de contact de l'axe d'assemblage et permettent de ce fait d'assurer l'étanchéité des connecteurs hydrauliques ou autres connecteurs à l'état assemblé.
