Definitions

  • the present invention relates to an attachment, in particular an attachment for construction machinery.
  • Construction machines generally have a working implement, such as an excavator, which is equipped with a tool carrier, for example in the form of a swivel arm.
  • a tool carrier for example in the form of a swivel arm.
  • Conventional attachments have for this purpose a frame which is attachable via a coupling device to the equipment carrier and on which a specific tool is provided.
  • a tool drive is also provided on the frame.
  • this describes the WO 96/02708 A1 a concrete pincers with two jaws, each with concrete crushing sections and cutting edges to separate the concrete breaking and cutting functions, optimizing the respective tool components for their functionalities.
  • the WO 97/30232 A1 shows a Betonbrechzange with a first pair of jaws, which is designed for breaking concrete slabs, and a second pair of jaws, which is designed for cutting steel beams.
  • Such tools with multiple functions here: breaking concrete slabs and cutting steel beams) reduce the number of available tools or attachments.
  • quick-change devices with which a quick change of a complete attachment to a working device or on the device carrier can be performed.
  • the interruption times can be shortened on the construction sites and thus perform the work more effective and cost-effective.
  • Such quick-change devices for attachments are, for example, in the documents DE 102 00 836 A1 . DE 44 17 401 A1 . DE 94 08 196 U1 and DE 92 09 675 U1 disclosed, these quick-change devices are each adapted to specific types of attachments.
  • the disclosed WO 01/68992 A1 a demolition shear with a fixed and a movable scissors jaw.
  • the movable scissors jaw is movable about a hinge with a bolt relative to the frame and thus also relative to the fixed scissor jaw.
  • the JP 2001-288769 A discloses a blade tool which is pivotable about a hinge. A two-piece pin of this joint can be moved by means of a hydraulic pin drive for releasing or holding the blade tool.
  • the two tool parts are in each case releasably connected to the tool drive or the rigid holding device on the frame via the at least one second linking device and b) the bolt of the joint can be removed at least partially from the joint by a bolt drive provided on the frame is to be able to solve the two tool parts of the joint can.
  • the tool with the two tool parts can be detached from the frame of the attachment, on the one hand, the connection between the tool parts and the tool drive via the at least one second hinge device is released and on the other hand, the bolt at least partially removed from the joint provided on the frame becomes. Since the removal of the bolt takes place via a bolt drive provided on the frame, ie, does not have to be carried out manually, the tool change can be carried out more simply and faster than with conventional attachments.
  • the frame of the attachment denotes the basic structure of the attachment, which is on the one hand connectable to a working implement and on the other hand carries all the components of the attachment, in particular the tool and the tool drive. He is not up a frame shape restricted in the strict sense, but can also take on housing shapes, skeleton shapes and the like.
  • Suitable attachments to which the invention may be applied are, for example, demolition and scrap shears, demolition and scraping tongs, concrete crushing tongs, combination tongs, pulverizers, demolition and sorting grabs, and the like.
  • the bolt of the joint of several, in the longitudinal direction of the bolt releasably interconnected bolt parts is formed, of which at least one bolt part is removable by the bolt drive from the joint.
  • at least two bolt parts of the bolt can be removed from the joint by the bolt drive.
  • the bolt drive for removing the bolt from the joint can be made smaller.
  • the pin drive may comprise at least two drive elements configured to remove two pin parts of the pin from each other in opposite directions from the joint.
  • the bolt drive can be designed, for example, as a hydraulic bolt drive or as an electromotive bolt drive. A combination of multiple drive types is conceivable here.
  • a switching element is also provided for switching the supply or control, retrofitting the supplies and / or controls (eg hydraulic system) of the implement and the equipment carrier are not required.
  • the attachment drive hydraulics can be used to rotate the bolt drive.
  • the releasable bolt or the releasable bolt parts of the bolt is / are biased in their position (s) for holding the tool parts.
  • the releasable bolt or parts may be lockable in position (s) for holding the tool parts.
  • the at least one second articulation device of the tool drive can be connected to the joint via at least one lever. This lever causes a guide of the movement of the second linkage, which is coupled to the tool parts.
  • This at least one lever can be designed, for example, rigid or adjustable in length.
  • a supply and / or control of a drive for length change of the lever may be formed for example by a supply or control of the drive of the attachment and / or the tool drive.
  • the switching of the drives takes place, for example, parallel to the switching operation for the bolt drive.
  • a length-adjustable lever can also be a game between the first and second engagement elements of the second link means, which can arise over time, be compensated.
  • the at least one second articulation device of the tool drive can have a first engagement element provided on the tool drive and a second engagement element provided on a tool part, which is detachably engaged with the first engagement element.
  • the one element of the first and second engagement elements may be configured as a hook-shaped engagement element and the other element of the first and second engagement elements may be configured as a rod-shaped engagement element which is removable from the hook-shaped engagement element transversely to its longitudinal direction.
  • the one element of the first and the second engagement element may be configured as a cylindrical engagement element and the other element of the first and the second engagement element as a bolt-shaped engagement element, which is removable in its longitudinal direction from the cylindrical engagement member.

  • a hydraulic system is conventionally provided on the implement 10, which is connected to the hydraulic tool drive 20 (for moving the tool) and a hydraulic attachment drive (for rotating the attachment about its longitudinal axis) via hydraulic lines routed along the implement carrier 12.
  • the attachment is attached via a coupling device to the equipment carrier 12, which also establishes a connection of the corresponding hydraulic lines.
  • the attachment 14 is configured so that the tool 18 can be solved by the frame 16 and the tool drive 20 of the attachment 14. This allows the implement to be quickly adapted to the various on-site work to be done to shorten downtime without having to provide a large fleet of machinery with a large number of different complete attachments.
  • the frame 16 serves as a support for the respective tool 18 and the corresponding tool drive 20.
