Definitions

  • the invention relates to a device for conveying of pasty masses, especially concrete, consisting of an at least two-cylinder pump in collimated array, each cylinder having a piston which is driven in opposite directions to the other pistons, this ufgabebe the cylinder of an approximately funnel-shaped final A - Containers feed the masses alternately via a pipe distributor to a pressure line and the funnel-shaped area of the feed container is closed 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 alternately closed by the vertically standing distributor pipe, whereby the distributor pipe is pivotally mounted, is stepped with axially parallel end sections and is connected to a shaft coaxially to its outlet opening, that the axes of the shaft and the outlet opening of the distributor pipe and that of the public Openings in the control plate are aligned axially parallel - here forming a triangle with two equal legs - the outlet opening, ie the end of the distributor pipe leading to the pressure line, being pivotable by means of
  • Such a device is identified by DE-PS 21 04 191, wherein 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.
  • the solution to this problem according to the invention provides that the pivot shaft is mounted outside of the feed container.
  • This arrangement achieves the coaxial alignment of the openings in the control plate and the inlet section of the distributor pipe and the coaxial alignment of the outlet section of the distributor pipe with the swivel shaft with axially parallel alignment of the swivel part of the swivel pipe and the swivel shaft.
  • the swivel shaft can generally take place on the wall of the feed container facing it by means of two bearings which are arranged at a relatively large guide distance from one another or on bearings which are fixed to a supporting structure which is fixedly assigned to this container.
  • a special embodiment of the connection between the step-shaped 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 to the outlet opening of the distributor pipe by means of an arrangement arranged on the step, for example the flange connection is directed towards their angle.
  • the intermediate pipe may be connected to an intermediate shaft which is assigned half of 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 keyway or splined internal teeth or the like. Can 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.
  • an axially displaceable wear ring is arranged in a resilient manner in the inlet-side end section of the distributor pipe.
  • the proposed use not only includes the solution to the problem stated above, but also, in a simple manner, identifies a secure seal between the swivel tube and control plate, this being made possible by the storage of the swivel shaft outside the feed container.
  • delivery line and "pressure line” - both of which are used in the literaur - are to be interpreted 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 so that it can be pivoted alternately with its end facing the control plate 2, while the end facing the delivery line 5 to 7 is pivotally mounted in a coupling 4 and slidable 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. is firmly connected via the machine frame, not shown.
  • pivoting 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 - the pivoting shaft 11 is coaxially connected to the pivot shaft 11 via an intermediate shaft 11'.
  • Both parts are coupled via a detachable connection 8 and the pivot shaft 11 in the wall of the feed container 1 facing it in stock.
  • 9 and 10 mounted, the bearing 10 - not shown in the drawing - stepped in 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 equipped with a pivot lever 12, on which the drive of the pivotable distributor tube 3, which is formed by two brackets 14, acts.
  • An axially displaceable wear ring 25 is resiliently arranged in the end section 23 of the distributor tube 3, two disc springs being provided as the spring element, as shown in FIG.
