Definitions

  • the invention relates to a working device with a preferably designed as a stationary support column frame, with a motor-driven rotary head, which is rotatably mounted on a frame-fixed bearing block about a vertical axis of rotation, with an arm package consisting of several, on buckling or Push hinges in pairs relative to each other movable, a concrete conveyor line carrying boom arms, which arm package is articulated with its first mast arm about a horizontal axis of rotation on the turret, with a selectively via control elements or a radio link operable, a hydraulic assembly for controlling drive units for the turret and Mastarmamba having control mechanism and with a work platform fixed to the frame in the vicinity of the bearing block.
  • Trained as concrete pumps working equipment of this type have a distribution boom as a boom, which carries a concrete delivery line, which is connected to the pressure port of a frame fixedly arranged core pump.
  • a working device with the features specified in the introduction is known per se (EP-1 235 965 B1).
  • the components belonging to the drive mechanism of the turret are integrated there in the frame-fixed bearing block.
  • a major disadvantage of this design is that the working platform is narrowed by the parts mounted on the bearing block and therefore there is no sufficient space for the mechanic to move.
  • the necessary for hydraulic control of the arm package hose package is relatively large and bulky and further limits the movement space of the fitter at the relevant point.
  • a liquid tank suitably designed as an oil tank for the hydraulic assembly is arranged on the turret above the bearing block, which has an outer contour geometrically adapted to the turret.
  • the liquid tank may have a limited by its outer contour window opening, which is intended for example for the passage of a releasably arranged on the rotary head ballast boom.
  • a holder for receiving the cabinet can be arranged on the liquid tank, which is pivotable about an axis parallel to the axis of rotation of the rotary head relative to the window opening by at least 90 °.
  • the holder can be swiveled into the window opening with the control cabinet when there is no load balancer or can be pivoted out of the window parallel to an existing ballast extension.
  • the work platform which is free of add-on parts, allows the mechanic to ride with him without a problem and provides a good view of the arm package. By eliminating the disturbing attachments, the arm package can be placed close to the turret, thereby reducing the load torque generated thereby.
  • the turret has a base part arranged on the bearing block and an adapter piece comprising a bearing point for the ballast arm, the base part and the adapter piece being releasably coupled to one another via a separating point.
  • the base section and the adapter piece have at their point of separation in pairs positively connectable coupling elements.
  • the arranged on the oil tank window opening must be free by swinging out of the cabinet located on the holder.
  • the arm package is detachably coupled via a further adapter piece at one of the separation point of the ballast boom opposite second separation point with the base portion of the turret by means of pairwise positively connectable with each other further coupling elements. It is particularly advantageous if the base part and the adapter piece in the region of the second separation point in pairs have positively connected with each other connectable coupling elements. Thus, it is possible that the arm package can be separated together with the other adapter piece in the region of the second separation point of the base portion of the turret, while the base portion remains together with the bearing block on the frame.
  • Figure 1 is designed as a concrete distribution boom working device with support column, arm package and ballast boom in a fragmentary exploded view.
  • Fig. 2a, b and c a section of the implement in perspective view
  • FIG. 3a to d four different perspective views of the mounted on the bearing block turret with attachments; 4 is a perspective view of the turret with bearing block,
  • the implement shown in the drawing is designed as a concrete pump with a stationary frame 10.
  • the frame 10 forms a supporting column which has at its upper end a substructure 14 with a bearing block 35 for a rotatable about a vertical axis of rotation 30 rotary head 32.
  • On the turret 32 each one designed as an arm package 34 and ballast carrier 134, pointing to opposite sides of the support column boom 16, 116 is arranged.
  • the arm package 34 has a pair of mutually pivotable, a concrete conveyor line 22 supporting mast arms 1, 2, 3, 4.
  • the boom 16 with the first mast arm 1 of the arm package 34 in the mounted state is mounted pivotably about a horizontal pivot axis at a bearing point 36 of the rotary head 32.
  • a concrete boom boom 16 is releasably coupled via an adapter piece 52 at a separation point 54 with the base portion 50 of the turret 32 by means of pairwise positively connectable coupling elements.
  • the adapter piece 52 as a bolt-shaped or peg-shaped hooking elements 56, 57 formed coupling elements, while the base section 50 with upwards open-edged receptacles 58, 59 is provided for the suspension elements 56, 57.
  • the identifiable in Fig. 1 holes in the adapter piece 52 form the bearing point 36 for the boom 16 and the turret side pivot point 48 for the cylinder-piston unit 40th
  • a safety connection is additionally provided in the region of the separation point 54, which is produced by means of a plug-in or latching bolt 76 between the adapter piece 52 and the base part 50.
  • the plug-in or latching pin 76 can be retrofitted by an installer working platform 78 (Fig. 1) by a fitter. It can be seen from FIGS. 1 and 4 that, in addition to the base section 50 arranged on the bearing block 35, the rotary head 32 has a second adapter piece 152 comprising a bearing point 136 for an additional arm 116.
  • the additional boom 116 having a ballast carrier 134 is releasably coupled via the adapter piece 52 of the separating point 154 to the base part 50 of the rotary head 32 by means of coupling elements which can be positively coupled to one another in pairs.
  • a first group of coupling elements is designed as a peg-shaped suspension members 156 and a second group of coupling elements as provided with an open-edge receptacle 158 for the suspension members 156 hook members 157.
  • the suspension members 156 are arranged on the base portion 50, while the hook members 157 are arranged with downwardly open-edge receptacle 158 on the adapter piece 152.
  • the adapter piece 152 has a mounted in the state below the open-edged receptacle 158, under the action of the boom 116 about the axis of the Ein von Strukturorgane 156 generated load moment against the base portion 50 adjacent stop 120.
  • the adapter piece 152 is connected in the embodiment shown at two bearing points 136, 137 with the boom 116, wherein the La gerstellen 136,137 have a distance from each other especially in the vertical direction.
  • the boom 116 can also be mounted to the base section 50 by means of a crane.
  • the turret is equipped with a larger number of attachments, which have the following functions:
  • a hydraulic assembly 84 for driving drive units for turret and MastarmGHz having an oil tank 86 and a driven by an electric motor 87 hydraulic pump 88,
  • control mechanism 90 which can be selectively actuated via control elements 91 or a radio link 89 and accommodated in a control cabinet 92,
  • a drive mechanism 33 which has a hydraulic drive motor 94 and a slewing gear mechanism 96 for the rotary drive of the rotary head 32 with respect to the bearing block 35,
  • the oil tank 86 has a geometrically adapted to the turret 32 outer and inner contour. As can be seen in particular from Figs. 3a to d and 4, the oil tank 86 is provided with a window opening 98 which is intended for the passage of a mounted on the turret 32 ballast boom 134.
  • the ballast boom 134 must only be provided if the frame 10 is loaded so heavily due to the over the arm assembly 34 acting on the turret 32 load torque that it needs a load balance. If no ballast arm 134 is provided, the window opening 98 can be used to receive the control cabinet 92 for the control mechanism 90.
  • the oil tank 86 is opposite the window opening 98 about a to the axis of rotation 30 of the turret 32 parallel axis 100 pivotable holder 102 for receiving the cabinet 92 is provided. It is thus possible, in the presence of the ballast arm 134, to pivot the switch cabinet 92 out of the window opening 98 via its holder 102, so that it can be operated by the working platform 78.
  • control cabinet 90 with control mechanism 90 and the hydraulic assembly 84 with oil tank 86 and hydraulic pump 88 are disposed on the base portion 50 of the rotary head 32 above the bearing block 35.
