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 Pivoting joints 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 an optionally via control organs or a radio link operable arranged in a control cabinet control mechanism and an oil tank and a motor-driven hydraulic pump having hydraulic assembly for controlling drive units for the turret and Mastarmamba, and with a frame fixed in the vicinity of the bearing block work platform.
  • Trained as concrete pumps working equipment of this type have a distri mast as a boom, which carries a concrete delivery line, which is connected to the pressure port of a frame fixedly arranged core pump.
  • the drive mechanism for the rotary head usually has a rigidly connected to the bearing block drive pinion.
  • the bearing block with its drive pinion is first inserted into the frame-fixed drive mechanism and then bolted to the frame. A lot of care is required so that the teeth of the drive pinion are not damaged. Therefore, the assembly is usually made at the factory.
  • many construction sites can not be operated with concrete pumps due to lack of space.
  • the drive mechanism of the turret includes The components are integrated there in the frame-fixed bearing block. This is achieved in that a drive pinion arranged fixed to the frame carries a protruding over the frame coaxial pin and at least one eccentrically arranged Drehit Vietnameseelement, while the turret has a complementary to the mating pin, releasably attachable to this receptacle and at least one releasably engageable with the Drehmit curriculumelement entrainment.
  • the separation point between the frame and the boom is there between the bracket and the turret, so that the fairly heavy turret with drive assembly is part of the boom, which must be removed from the frame during the change process.
  • a major disadvantage of this design is also that the working platform is narrowed by the attached to the support column parts and therefore there is no sufficient space for the mechanic movement.
  • the arm package must be positioned relatively far away from the support column in order to avoid collisions with attachments to the support column. This leads to a large load torque.
  • 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.
  • the object of the invention is to improve the known implement to the effect that the overall height of the bearing block is kept relatively small and not necessary for the operation of the arm package attachments in emergency operation case do not interfere with the fitter.
  • the feature combination specified in claim 1 is proposed.
  • Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
  • the solution according to the invention is essentially seen in that the control cabinet with control mechanism and the hydraulic assembly with oil tank and hydraulic pump are arranged on the turret above the bearing block.
  • the hydraulic pump is expediently driven by an electric motor, which is also arranged on the turret. In this way, the freedom of movement of the mechanic on the work platform in maintenance and emergency operation is significantly improved.
  • a further improvement in this regard is achieved when the necessary for the turret drive drive motor and the associated slewing gear are also located on the turret above the bearing block. Since the hydraulic control is arranged in the rotary head area, only short, permanently piped lines are necessary between the control device and the coupling point.
  • 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.
  • the power connections and remote control lines routed via the stationary support column are routed inside to the bearing block, to which coupling points, such as sockets and quick-release fasteners are attached, which keep the working platform free.
  • the arm package can be placed close to the turret, whereby the load torque generated thereby can be reduced.
  • the bearing block By laying all attachments up in the turret, the bearing block can be made low, so that it does not interfere with the freedom of movement in the working platform.
  • control mechanism is supplied with electric current via an external power source and an electric cable guided over the support column and bridging the rotary connection between bearing block and rotary head.
  • oil tank on has the geometrically adapted contour of the rotary head, in which a window opening with an inner contour forming for the passage of a ballast arm mounted on the rotary head remains free.
  • the control cabinet for receiving the control mechanism can be arranged on a near-platform holder so that it is easily reached by the fitter.
  • a holder for accommodating the control cabinet which can be pivoted about an axis parallel to the axis of rotation of the rotary head, can be pivoted into the window opening or can be pivoted out of the window parallel to an existing ballast arm if the ballast boom is not present.
  • a further advantageous embodiment of the invention provides that the rotary head has a base section arranged on the bearing block and an adapter piece comprising a bearing point for the arm package, the base section and the adapter piece being releasably coupled to one another via a separating point.
  • the base section and the adapter piece have coupling elements which can be positively connected to one another in pairs at their point of separation.
  • the boom can be separated together with the adapter piece in the region of the separation point of the base portion of the turret, while the base part remains together with the bearing block on the frame.
  • the ballast boom is detachably coupled via a further adapter piece at one of the separation point of the arm package opposite second separation point with the base portion of the turret by means of pairwise positively connectable with each other further coupling elements.
