Definitions

  • the invention relates to a device for coupling and Uncoupling the connection ends of pressure medium lines, especially of hydraulic lines, with a fixed one and one mounted on a movable sled Coupling half by a piston / cylinder unit is movable in the coupling and / or uncoupling position, in particular on tool quick-change devices from Bauoder Agricultural machinery.
  • Such a device is described, for example, in DE 33 11 502 C2.
  • a hydraulic excavator is provided by a hydraulic-mechanical Locking can be positively connected are, whereby the device is characterized is supposed to separate control line connections by means of a hydraulic actuator are connectable or separable from each other.
  • the control line connections are spring-loaded and are in the plane perpendicular to their opening or can move the closing direction.
  • a hydraulic one works for this Actuator against a spring that moves Control line connections against the existing part assigned control line connections.
  • a particular disadvantage of this type of device is that that through the horizontal freedom of movement of each Controls are insufficient guidance and fit can be achieved in operation, whereby Deadlocks and the like can occur.
  • the object of the present invention is therefore a robust and durable device for coupling and uncoupling the connection ends of pressure medium lines create, especially after the completion of the coupling process the pressure supply to the actuating cylinder is interrupted can be a costly additional pressure supply here to be avoided even during operation.
  • this object is achieved in that the slide in the dome position by a self-holding, mechanical, operated by the pressure piston Lock is fixable.
  • Such a lock enables the carriage, after being moved to the dome position and thus the two coupling halves connected to each other has been mechanically fixed in position, so that it stays in it even after the pressure is applied to the actuating cylinder is interrupted or, for example due to slow pressure drop in the hydraulic system breaks down by itself. It is particularly advantageous that the mechanical locking by the pressure piston self-operated and thus additional active Elements in the coupling element can be avoided.
  • Embodiments of the invention result from the subclaims.
  • Device is provided that the lock in shape spring-loaded locking lever with recesses is designed to engage in grooves.
  • This configuration of the lock enables a safe Fixing the slide and thus the coupling halves in coupled position. It can be great Take up forces, even when the actuating cylinder is depressurized becomes.
  • the two coupling halves remain in the coupled state in their position.
  • the lock ensures that even when the actuating cylinder is depressurized secure connection of the two coupling halves guaranteed is.
  • decoupling for example Sliding sleeve actuated by the actuating cylinder, so that the Coupling is decoupled and then the two Coupling halves are separated from each other.
  • the working length of the piston / cylinder unit to effect an idle stroke The lock opens before the carriage moves from the dome position and / or to close the lock after moving the carriage to the dome position is larger than the travel of the slide.
  • a special embodiment of the device provides that the carriage points in the direction of movement, on both sides has open sliding bushes.
  • a further embodiment of the device is thereby characterized that the sliding bushes on one side on fixed part attached sliding pin, which is a length have larger than the sliding bushes, slidably arranged are.
  • This type of construction and storage of the sled are linked to great stability can be implemented with a simple structure.
  • One embodiment of the invention provides that the sliding pin at the free end the transverse grooves for receiving the swiveling spring-loaded on the slide Have locking levers.
  • the Locking lever have sliding surfaces and the piston of the pressure cylinder corresponding conical surfaces having. This configuration is particularly advantageous Locking of the slide in the coupled state possible.
  • the locking lever can by the Printing cylinders are operated and thus without any further active Elements for fixing the sled in its provide an end position.
  • Another embodiment of the device according to the invention is that between the end of the sled and a driver at the free end of the pressure piston Delay spring is provided. This makes it special simply ensures that the sled during the Empty stroke of the pressure piston already in the coupled position remains before the mechanical lock is activated or that the lock is opened before the sled from the coupled to the uncoupled Position moved.
  • the protective sleeves serve the purpose of the coupling halves against dirt and mechanical stress through the harsh work environment in which this Devices commonly used to protect. As a result, the greatest possible shielding of the Coupling parts both in the coupled and in the uncoupled Condition allows.
  • FIGS. 1a to 1c areas of a Excavator boom, not shown, on the one hand and a tool, e.g. a spoon, reproduced the with the invention generally designated 1 Device are equipped.
  • Stick and backhoe are with quick-change elements, designated in Fig. 1a with 4 and 5, equipped, on which elements of the invention Device 1 are attached, as an example a fixed one on element 5 of the bucket Part 2 and on element 4 on the excavator arm a movable Part 3, each equipped with the hydraulic lines to be connected 6 and 7 to be coupled at their free Ends with the corresponding coupling halves, in the Figures with 8 and 9 designated, are equipped, wherein the coupling halves 8 and 9 of one another metallic protective sleeves 10 and 11 are surrounded.
  • the coupling halves 8 to be moved are on one Carriage 12 optionally interchangeably attached, what in the figures is not shown in detail, the carriage by means of a piston / cylinder unit 13, 14 from a Decoupling position (Fig. 2a, Fig. 4a) in a coupling position (Fig. 2b, Fig. 4b) are movable.
  • the one in Printing cylinder 13 movable piston 14 has on its free, outwardly facing end a conical surface 15 to act on two locking levers 16, arranged perpendicular to the axis of the piston 14, which is coupled in the Condition for locking the carriage 12 serve.
  • the piston 14 of the pressure cylinder 13 is also still equipped with a driver 18, which in turn is equipped with a spring 17, the one hand on Driver 18 and on the other hand on the end face 12a of the Carriage 12 supports.
  • the carriage 12 is shown in FIGS Examples formed by two bushings 19, the via a front 12a of the carriage 12 forming Sheet metal are interconnected, the bushings 19th are movably guided on sliding pin 20.
  • the length of the sliding pin 20 is greater than that Length of the bushings 19 such that the free end of the Sliding pin 20 in the locked position (for example Fig. 4b) projects beyond the end plate 12a of the slide.
  • This free outward end of the sliding pin 20 is equipped with a transverse groove 22 into which one of the locking levers 16 with a correspondingly shaped end can intervene when the clutch is closed, whereby the locking lever 16 of springs 21 in the closed position are forced.
  • the carriage 12 is in the uncoupled state removed from the fixed part of the device 2.
  • the impression cylinder 13 retracts the piston 14 by the driver 18 via the spring 17 the carriage on the fixed Moved part of the device 2.
  • the printing cylinder 13 is now retracted further, creating the link surface of the locking lever 16 over the conical surface 15 of the piston 14 slip.
  • the piston 14 moves out of its retracted position Position outwards and slide with the cone surface 15 first the levers 16 against their backdrop surfaces the spring force of the springs 21 away from the slide pins 20, so that the recesses no longer fit into the transverse grooves 22 intervention.
  • the carriage 17 by the spring still held in the coupled position until the Locking lever 16 completely moved out of the transverse grooves 22 are.
  • the slide 14 by the piston 12 from its coupled to the uncoupled position move and separate the two coupling halves 8 and 9, so that the protective sleeves 10 and 11 are not mesh more.
  • the movable coupling half 8 is on the one Movable piston / cylinder unit, not shown here Carriage 12 attached.
  • the carriage 12 is on Sliding bushes 19 arranged on sliding pin 20 are stored.
  • the hydraulic piston / cylinder arrangement moves the movable coupling half for coupling 8 in the direction of the fixed coupling half 9.
  • An arranged in extension of the same socket 19 Centering pin 26 slides into the centering holes 27 on the fixed coupling half 9, um for a sufficiently precise alignment of the two coupling halves 8 and 9 to worry about each other.
  • the invention is not based on the embodiment limited.
  • the number and design the coupling elements are variable, so that in particular more than two lines connected at once can be. It is also possible not only hydraulic, but also other pressure lines to couple with each other or electrical connections.
