Definitions

  • the invention relates to a device for conveying pulpy masses, in particular concrete, consisting of a two-cylinder pump in a parallel arrangement, each cylinder having a piston which can be driven in opposite directions to the other piston, in this case the cylinders from an approximately funnel-shaped feed container, the masses alternately via a pipe distributor to a pressure line and the bottom of the funnel-shaped area of the feed container is formed by a flat control plate provided with two vertical openings, the openings of which are connected to the cylinders of the pump and can be connected alternately to the pressure line through the vertically standing distributor pipe, wherein the distributor pipe is pivotally mounted, is stepped with axially parallel end sections and is connected to a shaft coaxially to its outlet opening, the axes of the shaft and the outlet opening of the distributor pipes s are aligned axially parallel to the axes of the openings in the control plate - in this case forming a triangle with two identical legs - and the outlet opening, ie. H. the end of the distributor pipe leading to the pressure
  • Such a device is identified by DE-PS 21 04 191, according to the drawing, Figures 1 to 4, the shaft inside the container through the control plate and is adjustable according to claim 1 in the axial direction via a nut ..
  • openings in the control plate are each provided with a detachably connected wear ring.
  • DE-OS 30 03 247 provides uniform coverage of the wear material over the entire swivel range of the distributor pipe.
  • the solution to this problem according to the invention provides that the pivot shaft is mounted outside on one side of the feed container, and that the pivot shaft is supported by bearings arranged on the wall of the feed container facing it or on a supporting structure permanently assigned to the feed container.
  • a special embodiment of the connection between the stepped distributor pipe and the pivot shaft provides that the step of the distributor pipe runs at any angle between its axially parallel end sections and the coaxial connection of the pivot shaft with the outlet opening tion of the distributor pipe by means of a flange connection arranged on the step and oriented approximately at the same angle.
  • an intermediate shaft is connected to the distributor pipe, which half is assigned to the detachable connection. Due to the intermediate shaft connected to the distributor pipe, the accessibility of the connection point can be significantly improved, so that assembly and disassembly can be carried out quickly.
  • the releasable connection is a claw or flange connection or a sleeve connection, the parallel key groove or multi-spline internal toothing or the like being designed to be able to be guided via the correspondingly designed pivot shaft.
  • the spring preloading device can include both the arrangement of coil springs, disc springs and that of rubber springs.
  • the use of pneumatic springs is also conceivable.
  • an axially displaceable wear ring to be arranged resiliently in the inlet-side end section of the distributor pipe.
  • Such a design allows the already described fixed connection of the distributor pipe to the pivot shaft via the flange connection provided on the step, which can generally be referred to as an oblique flange connection.
  • the wear ring is supported by two disc springs.
  • delivery line and “pressure line” - both of which are used in the literaur - are to be regarded as the same in terms of content.
  • the feed container 1 tapers downward approximately in the shape of a funnel and is closed off by a control plate 2 which acts as a bottom and which in turn has two openings 3 'and 3 "leading to the cylinders 2' and 2".
  • the stepped distributor pipe 3 is arranged alternately with its end facing the control plate 2, while the end facing the delivery line 5 to 7 is pivotable in a coupling 4 and is displaceable in the axial direction.
  • the upper part of the coupling 4 is fixed on the deflection knee 5; the deflection knee 5 leads via the feed pipe connection 6 into the feed pipe 7, one of the parts 5/6 with the feed container directly or indirectly - e.g. B. on the machine frame not shown - is firmly connected.
  • the pivotable distributor pipe 3 is coaxially connected to the swivel shaft 11 via an intermediate shaft 11 'in its end section 23' directed towards the coupling 4 - which is aligned axially parallel to the end section 23 extending to the control plate 2.
  • Both parts are coupled via a detachable connection 8 and the pivot shaft 11 is mounted in the wall of the feed container 1 in bearings 9 and 10, the bearing 10 - not shown in the drawing - graded in terms of its inner clear diameters and the correspondingly formed end of the shaft is adjustable in a known manner in the axial direction.
  • both the coupling 4 and the releasable connection 8 can be equipped with a spring pretensioning device that is effective against the control plate 2.
  • a practically equally effective arrangement can be made in connection with the bearing 10 and the downward end of the pivot shaft 11.
  • the intermediate shaft 11 ' is with equipped with a pivoting lever 12, on which the drive of the pivotable distributor pipe 3, which is formed by two brackets 14, engages.
  • An axially displaceable wear ring 25 is resiliently arranged in the end section 23 of the distributor pipe 3, two disc springs being provided as the spring element, as shown in FIG. 5.
