Definitions

  • the invention relates to a work machine, in particular an excavator, the is preferably used as an excavator and for general cargo handling.
  • a variety of different machines are known, which are designed either as excavators or for general cargo handling. Although it is possible in principle to use such a machine designed for one purpose for the other purpose, there is the problem that an excavator is designed for powerful, tearing use, the excavator operation, and not for fast lifting of loads.
  • hydraulic cylinders are usually arranged on a working arm, which have a large oil column, for the mostly short but powerful pulling movements of the excavator bucket.
  • the small oil column of the hydraulic cylinders is intended for a lifting movement of the excavator bucket. There is therefore only a limited force available for this lifting movement. As a result, the movements of an excavator cannot be used for effective general cargo handling.
  • the invention has for its object to propose a machine that is equally suitable for excavator operations as well as for general cargo handling and can do both jobs efficiently.
  • the telescope is at least three-part telescope is formed.
  • the telescope is automatically in the respective position is designed to be lockable.
  • each of the two cylinders for a particular purpose is provided and the other cylinder then as a push rod and / or pull rod serves. It is also conceivable for both cylinders to work together in certain cases Movements of the working arm.
  • the Working tool arranged from the end of the working arm remote from the machine is designed to be interchangeable.
  • a further development of the invention also teaches as very advantageous that the Tool is designed to be folded away.
  • the tool is simple and requires little effort from the Removable working position; the tool is secure on the working arm in one Quiet location housed.
  • Tool is designed to be retractable into the working arm.
  • a further development of the invention is that at least one other Tool is arranged on the working arm.
  • Tools on the working arm are arranged so that when retracting or extending the Telescope of the working arm the tools are changed.
  • the tool unit is designed to be exchangeable, foldable or displaceable overall.
  • Telescopic cylinders with at least two push / pull rods are provided.
  • Lever devices on the working arm engage at least two cylinders, one of which at least one for each of at least two applications of the Work arm are provided.
  • An advantageous development of the invention is also that cylinders in Working arm are arranged.
  • cylinders are arranged within the unit of tool and actuators.
  • Another advantageous embodiment of the invention is that on the Machine away end of the working arm a support element, preferably removable, foldable or slidable, is arranged.
  • Such a support element is mainly used in difficult terrain; around itself moving out of a swampy hole with an excavator is extremely helpful if you can support yourself with the working arm.
  • an example Plate conceivable as a support element. Because the support element is removable, can be folded away or pushed away, it prevents normal Use of the machine is not.
  • FIG. 1 denotes a work machine with a work arm 2.
  • a Tool 3 On from Drive of the working machine 1 facing away from the end of the working arm 2 is a Tool 3 arranged, which is designed as an excavator shovel in this illustration.
  • the working arm 2 is in a lower main arm 4 and an upper boom 5 divided, which are interconnected via a joint 6.
  • the inclination of the Main arm 4 can be changed via a hydraulic mechanism, not shown become.
  • the boom 5 is relative to the main arm 4 by a on the main arm 4th arranged hydraulic cylinder 7 moves.
  • the rod 8 of the cylinder 7 shows in Direction of the boom 5, whereby the lowering, i.e.
  • pulling movement of the Boom 5 corresponds to the large oil column of the hydraulic cylinder 7, whereby again a greater power yield can be achieved with pulling movement.
  • At the Boom 5 is also at least one in the vicinity of the tool 3 Hydraulic cylinder 9 attached to the tool in the direction of the boom can swing. This arrangement represents that of a typical excavator.
  • a part of a work machine is shown, the main arm 14 of the Working arm 12 as a telescope with an outer part 15 and one in this outer part 15 inserted inner part 16 is equipped.
  • On the outer part 15 is a Locking mechanism 17 attached, which fixes the inner part 16 in the outer part 15 and prevents accidental shifting.
  • the Force transfer between outer part 15 and inner part 16 improved.
  • On the top and Bottom of the main arm 14 cylinders 18 and 19 are arranged.
  • the cylinder 18th attacks via a receptacle 30 on the inner part 16.
  • the cylinder 19 is slidable in a rail 31 mounted on the outer part 15 and is in its working position over a Locking system, not shown, locked.
  • the cylinder 19 can the cylinder 18 support in excavator operation and vice versa, the cylinder 18 can the cylinder 19 support with general cargo handling.
  • a cylinder 18 is provided on the upper side of the main arm 14, whereas two cylinders 191 and 192 are arranged for general cargo handling, which are connected to one another via a lever 22, which has one end is rotatably mounted on the outer part 15.
  • a lever 22 which has one end is rotatably mounted on the outer part 15.
  • a telescopic cylinder 32 To push or pull the Inner part 16 from or into the outer part 15 is a telescopic cylinder 32 below the Cylinder 18 attached.
  • the telescopic cylinder 32 also changes the position of the Point of attack of the cylinder 18 on the outer part 15.
  • FIGS. 6 and 7 the cylinders 18 and 19 are each as Telescopic cylinder formed, each as in Fig. 2 and 3 on the upper or Bottom of the main arm are attached
  • the cylinder 18 is another Cylinder 181 assigned longitudinally, which supports the cylinder 18 and any Length compensation.
  • the working arm 2 in FIGS. 8 and 9 shows yet another arrangement of the Hydraulic cylinder 18 and 19.
  • the rod 23 of the cylinder 19 is on the outer part 15 of the Main arm 14 attached.
  • the first cylinder is - like cylinder 7 from FIG. 1 - for pulling movement of the boom 5 is provided, whereas the second cylinder for lifting movements of the boom 5 is formed when handling general cargo.
  • the second cylinder also acts with its when the boom 5 is lifting large oil column, which also results in a large power yield.
  • the second The cylinder remains in a defined position when the excavator is used whereas the first cylinder when using the work machine 1 for General cargo handling remains in a defined position. If the inner part 16 pulled out of the outer part 15 as far as possible, so the first cylinder is up to a defined position extended around the larger radius of the main arm 14 compensate. Now only the second cylinder works for lifting movements the boom 5.
  • first and second cylinders engage a lever that is rotatably supported at one end on the outer part 15. If the inner part is 16 pushed as far as possible into the outer part 15, so the first cylinder is supported additionally directly from the outer part 15, which causes the large forces that occur when excavator operation of work machine 1 is particularly good from the first cylinder to the Main arm 14 are transmitted. The lever is thereby in the excavator operation relieved. Due to the inner part 16 pushed into the outer part 15 Main arm 14 extremely stable against bending stress. If the inner part 16 pushed as far as possible out of the outer part 15 and with the Locking mechanism 17 locked, so the inner part 16 can be released from the outer part 15 of the locking mechanism 17.
