  • the quick release end sections as Claw coupling are formed, with an end portion with pivotally mounted claws is provided by a closed position, in which the claws a paragraph of the associated, other end section reach behind and thereby both end sections together are connected, can be moved into an open position, in which the claws release the heel and the End sections are separable.
  • the claws spring loaded and by the springs in be biased to its closed position.
  • the claw coupling can be operated remotely spring-loaded claws in an advantageous development the invention fluidically, preferably hydraulically by the closed position can be converted into the open position his.
  • a cylindrical ring-shaped projection is recorded in the assembled Condition of the pipe segments.
  • a cylindrical ring-shaped sealing element can be arranged which the cylindrical projection is supported on the front such that the two end sections are liquid-tight are interconnected.
  • the support arm segments articulated with each other by joints be connected. This allows the support arm design foldable. It can be an advantage if the pipe segments are articulated in the area of the joints are interconnected.
  • the support arm segments can be transferred into a transport position in which they are essentially parallel to each other are arranged.
  • the support arm segments can be in their Transport position may be arranged one on top of the other.
  • the pipe segments on the associated support arm segments be attached.
  • it can telescopic support arm segment an extendable sub-segment and have a fixed subsegment, the pipe segment is attached to the extendable sub-segment that is slidably received in the fixed subsegment. It is also conceivable that the pipe segment on the fixed Sub-segment is attached.
  • the Concrete pump is arranged on a chassis.
  • the assembly of the Show device on a truck chassis.
  • Pump line end a hose-like extension to Distributing the pumped concrete can have.
  • the telescopic segment is transferred into its telescopic position and then the feed device from its rest position in their feed position is transferred.
  • Fig. 1 shows the device 1 for pumping concrete on a truck chassis 2 is firmly mounted. At the back the chassis 2 is a pump drive 3. Off the pump drive open pipe segments 4, which together a Form pump line 5.
  • the tube segments 4 are each on support arm segments 6 attached.
  • the support arm segments 6 are each via joints 7 articulated together.
  • the pipe segments are also 4 articulated to one another at the joints 7.
  • the support arm segments 6 for Transport of the device 1 folded onto each other.
  • a Working position form the support arm segments 6 one cantilevered support arm 8, the one via a swivel 9 vertical axis rotatably mounted on the truck chassis 2 is.
  • Transferring the support arm 8 from his Transport position in its working position is done by means of several hydraulic cylinders 10. If the device 1 is in its working position Line end 11 in the pump line 5 at the end of the widest cantilever arm segment 6.
  • One of the support arm segments 6 is a telescopic support arm segment 12, which is an extendable Has subsegment 13 and a fixed subsegment 14.
  • the Extendable subsegment 13 is telescopic in the axial direction extendable stored in the fixed sub-segment.

  • This additional pipe segment 16 is from one on the telescopic support arm segment 12 attached feed device 17 held.
  • the Feed device 17 has a, about an axis parallel to Longitudinal extension of the telescopic support arm segment 12 extending axis of rotation pivotable bracket 18.
  • In the Bracket 18 is the additional pipe segment 16 in the direction of it Longitudinal axis axially displaceable.
  • a indicated thickened spring 19 shown in the holder 18 spans the additional pipe segment 16 in the direction of Telescopic process when transferring the telescopic Support arm segment 12 from its collapsed Starting position in its telescopic position.
  • the Bracket 18 is from a first position in which the Additional pipe segment 16 outside of the pipe segments 4 occupied volume is arranged in a second Position transferable, in which at least one end section 20 of the additional pipe segment 16 with at least one End section 21 of one of the pipe segments 4 is aligned. From Fig. 3, the holder 18 can be removed in its second position. In addition, it can be seen in FIGS. 2 and 3 that in the direction the longitudinal extent of the telescopic support arm segment 12 always an end portion 20 of the additional pipe segment 16 in essentially level with one of the end sections 21 the pipe segments 4 is arranged. 2 and 3 can also be seen that between the near Additional pipe segment 16 arranged pipe segments 4 a Separation point 22 is located.
