Definitions

  • the invention relates to a work machine according to the preamble of claim 1.
  • a mast working machines such as mobile concrete pumps, pump mixers, excavators or cranes
  • the mast arms are stacked in the folded state while only the last, a free end having mast arm is supported with its free end or near the free end on a chassis-fixed support means.
  • the other superimposed mast arms are supported only on the next lower mast arm.
  • supporting devices are often arranged on the mast arms, on which each of the next upper mast arm of the folded mast is supported.
  • pump mixers which usually have a much smaller mast than a truck-mounted concrete pump and on the chassis due to other facilities such as the mixing drum little space is available, such support is often not possible.
  • JP S62 140088 U discloses a work machine according to the preamble of claim 1.
  • the invention is based on the idea, in the region of the two mast arms pivotally interconnecting joint, which is always in the folded state of the mast at one of the two ends of the package formed by the superposed mast arms to provide a support at a location at the more space exists as in the middle of the mast arms. It is possible that only one joint is supported on a preferably chassis-fixed support means. However, it is preferred that several or all joints are each supported on a supporting device, in which case a number of supporting devices corresponding to the number of supported joints must be present.
  • the component of the respective joint which rests on the support surface of the support device, for example, be a rotatably connected to the two mutually connected by the joint mast arms lever which serves to transmit a force for mutually pivoting the mast arms, such as a lever. It is in the supported member about a two parts of the joint pivotally interconnecting hinge pin, which is supported on the support surface in question.
  • the hinge pin may have a sleeve enclosing it, which rests on the respective support surface. At least one of the hinge pins has a supporting part protruding in the axial direction over the hinge parts connected by it, which supporting part is supported on the respective supporting surface.
  • each of the support parts can advantageously be mounted on a rotatable about a longitudinal axis of the hinge pin role, which rests on the support surface in question.
  • the hinge pin role When placing the role on the support surface of the hinge pin usually performs a movement with a component parallel to the support surface, so that the roll rolls on the latter. This leads to a protection of the support surface, especially if the role of soft, wear-resistant plastic is performed.
  • At least one and preferably each of the support surfaces Suitably extends at least one and preferably each of the support surfaces so far in a direction perpendicular to the longitudinal axis of the associated hinge pin, that it projects beyond the roller on both sides.
  • the roll then has enough space to roll on the support surface during the entire deposition process.
  • at least one and preferably each of the support surfaces has a channel shape with a bottom surface and side walls extending obliquely upward on both sides from perpendicular to the longitudinal axis of the hinge pin edges of the bottom surface. The side walls lead when rolling the role on the support surface to a centering of the role, by diverting them to the bottom surface.
  • another chassis-fixed support device may be provided, on which the free end of the last mast arm is supported in order to further improve the support of the entire mast.
  • the further support means may be planked with a sliding pad made of wear-resistant plastic, as well as the support surface may be formed of wear-resistant plastic.
  • a plastic for the planking of the other supporting device for the support surface (s) and for the role (s) is in particular an aramid and in particular a designated as polyaramid 6 plastic in question.
  • Fig. 1 is a partial section of a pump mixer 10 is shown, which has a chassis not shown in detail and a chassis fixed, one about a vertical axis of rotation rotary head 12 having mast block 14.
  • the pump mixer 10 also has a mast 16 on, which carries a concrete conveying line 18, with the concrete by means of a concrete pump can be promoted to a site.
  • the mast 16 has four pivotally interconnected mast arms 20, 22, 24, 26, wherein a first of the mast arms 20 is pivotally mounted about a horizontal pivot axis on the rotary head 12.
  • a second of the mast arms 22 is pivotally connected by means of a joint, not shown here, to the first mast arm 20 and by means of a joint 28 with a third of the mast arms 24.
  • the third mast arm 24 is finally connected by means of a joint, not shown, with a fourth of the mast arms 26, which has a free end 30, at or near which also the concrete conveyor line 18 ends.
  • the joint 28 connecting the second mast arm 22 to the third mast arm 24 has a deflecting lever 34 acted upon by a hydraulic cylinder 32, the force exerted by the hydraulic cylinder 32 causing the third mast arm 24 to pivot relative to the second mast arm 22.
  • Identical or similar joints are also disposed between the first mast arm 20 and the second mast arm 22 and between the third mast arm 24 and the fourth mast arm 26, but not shown in the drawing.
  • the joint 28 has two mutually spaced web plates 36 and the web plates 36 interconnecting, rotatably performed by each of the web plates 36 hinge pin 38 having a projecting in its axial direction on the outside of the web plates 36 supporting part 40.
  • the web plates 36 are articulated on the one hand on the third mast arm 24 and on the other hand on a piston rod 37 of the cylinder 32.
  • a connection with the second mast arm 22 is given by both hinged on both sides of the second mast arm 22 at this and the hinge pin 38 lever 39.
  • a roller 42 is rotatably mounted plastic.
  • a chassis-mounted support means 44 is provided in the embodiment shown, which has an upwardly directed support surface 46.
  • the support surface 46 is formed by a substantially horizontally extending bottom surface 48 and two on both sides of the bottom surface 48 in a direction perpendicular to the longitudinal axis of the hinge pin 38 extending, with the bottom surface 48 an obtuse angle enclosing side walls 50 formed.
  • the channel shape of the support surface 46 acts centering when depositing the roller 42, so that the roller 42 does not have to fit exactly on the bottom surface 48, but slides down the respective side wall 50, if it is placed a little way next to the bottom surface 48.
  • the support surface 46 also extends a distance in the direction perpendicular to the longitudinal axis of the hinge pin 38, so that the roller 42 can roll a little way on her when it is deposited on her.
  • a further preferably chassis-fixed support means 52 is provided on which a arranged at the free end 30 component 54 is supported.
  • the invention relates to a work machine 10 with a chassis, with a mounted on the chassis, a rotatable about a vertical axis rotary head 12 having mast block 14 and having at least two mast arms 20, 22, 24, 26 mast 16, wherein each of the mast arms 20, 22, 24 with the exception of a free end 30 having the last mast arm 26 from a first mast arm 20, starting with the respective mast arm 22, 24, 26 pivotally connected by means of a hinge 28 and wherein the first mast arm 20 um a horizontal pivot axis is pivotally mounted on the rotary head 12.
  • at least one preferably chassis-mounted support device 44 is provided, which has a support surface 46 on which a component of the joint 28 or a component of one of the joints 28 is supported.
