Definitions

  • the invention relates to a work machine, such as an excavator, and in particular to a tiltrotator of an accessory of the work machine.
  • An accessory such as a bucket may be hooked up to an excavator by adapting a tiltrotator, or a so-called rototilt, between a bucket boom and accessory of the excavator.
  • a tiltrotator or a so-called rototilt
  • This allows the accessory to be used in a diverse manner as it is easy, simple, and reliable to rotate and tilt the accessory.
  • the structure presents the challenge in which the breaking strain and, for example, excavating efficiency are rather considerably weakened compared to, for example, such a solution where the accessory is fastened directly to the end of the bucket boom.
  • Publication EP 2 208 828 discloses an arrangement for fixing a tool, in which an auxiliary body has been adapted between a boom and a tilting device. The structure is awkward and complicated, and requires changes in the boom end structure.
  • the tiltrotator of an accessory of a work machine includes a fixing arrangement for fixing the tiltrotator to an operating boom of the work machine, a fixing arrangement for fixing the accessory to the tiltrotator, a rotating device, and a tilting device.
  • the tilting device includes a body of the tilting device as well as an axle of the tilting device adapted within the body.
  • the tiltrotator has the fixing point of the operating boom end adapted below the plane of the upper surface of the tilting device body.
  • the idea of an embodiment is that the fixing point of the end of the operating boom is adapted on the same plane with the tilting device axle. This allows the breaking strain and excavating efficiency to be kept at a particularly advantageous level, and in addition the structure, as a whole, may be made simple and durable.
  • the tiltrotator includes a fork part having a branch part and arm part, whereby the branches of the branch part may be adapted in connection with the ends of the axle of the operating boom end located at the fixing point of the operating boom, and the arm part is fixed to the tilting device axle.
  • the fork part is adaptable to connect the axle of the operating boom end to the tilting device axle.
  • the fork part is fixed to a first end of the tilting device axle
  • the tiltrotator has a fixing part which is fixed to a second end of the tilting device axle to connect the second end of the tilting device axle to a swivel pin of the drive cylinder of a work machine.
  • FIG. 1 shows a tiltrotator of an accessory of an excavator.
  • the tiltrotator is a hydraulic device fixed to an end of a bucket boom 3 of an excavator.
  • the work machine is thus an excavator, whereby the operating boom of the work machine is a bucket boom 3.
  • an operator of the excavator may hydraulically rotate and/or tilt an accessory fixed to the tiltrotator from the cabin.
  • the accessory is a bucket 14.
  • the accessory may be a bucket, hydraulic hammer, vibrating plate or another accessory that may be used with an excavator or other work machine.
  • the tiltrotator includes a rotating device 11 and tilting device.
  • the tilting device has a body 1 and an axle 2 of the tilting device, adapted on the inside of it.
  • the body 1 may be turned in relation to the axle 2.
  • Such turning may be implemented by the use of, for example, hydraulic cylinders, screw thread/piston solution, vane motor solution or another method suitable for the purpose.
  • the structure and operation of the tilting device are known to such an extent to a person skilled in the art that they are not explained in any closer detail in this context.
  • the structure and operation of the rotating device 11 are also known to such an extent to a person skilled in the art that they are not explained in any closer detail in this context.
  • the bucket 14 acting as the accessory is fixed to the tiltrotator by a hook-like quick clamp.
  • the accessory may also be fixed to the tiltrotator with another type quick clamp or another suitable fixing method.
  • the tiltrotator is fixed to the end of the bucket boom 3.
  • the tiltrotator has a fork part 4, shown from above in Figure 2 .
  • the fork part 4 has a branch part 4a and arm part 4b.
  • the branches 4c, 4d of the branch part 4a are adapted in connection with the ends of the axle 5 of the bucket boom end at the fixing point of the bucket boom 3.
  • the arm part 4b of the fork part 4 is fixed to a first end of the tilting device axle 2. So, the fork part 4 connects the axle 5 of the bucket boom 3 end to the tilting device axle 2.
  • the centre point of the axle 5 of the bucket boom 3 end is on the same plane with the centre point of the tilting device axle 2.
  • the tiltrotator has a fixing part 23 fixed to a second end of the tilting device axle 2. So, the tilting device axle 2 extends through the tilting device 1, whereby the fork part 4 and fixing part 23 may be fixed to the ends of the axle 2 of the tilting device in a simple manner.
  • the fixing part 23 connects the second end of the tilting device axle 2 to a pin 22 of a swivel 21 of the drive cylinder of the work machine, which in the embodiment of Figure 1 is a bucket cylinder 20 of an excavator.
  • the upper surface of the body 1 of the tilting device is towards the bucket boom 3, and in the common usage situation shown in Figure 1 , the portion facing up.
  • the lower surface of the tiltrotator is the opposite in relation to the upper surface of the body, towards the accessory, and in the common usage situation shown in Figure 1 , the portion facing down.
  • the fixing point of the end of the bucket boom 3 is below the upper surface of the tilting device body 1.
  • the same matter may also be described so that in the common usage situation shown in Figure 1 , the plane of the fixing point of the end of the bucker boom 3 is lower than the plane of the upper surface of the tilting device body 1.
  • the marking F depicts the breaking strain of the bucket 14.
  • the marking h depicts the distance of the plane of the tip of the bucket 14 from the plane of the lower surface of the tiltrotator, and correspondingly also the length of the accessory.
  • the marking e depicts the distance of the plane of lower surface of the tiltrotator from the plane of the fixing point of the end of the bucket boom 3.
  • the breaking strain F of the excavator bucket 14 is at a fairly good level.
