Definitions

  • the invention relates to a thick matter pump with a Material feed container, two with their front Openings in the interior of the material feed container opening, hydraulically driven delivery cylinders, one engaging in the material feed container, with one end intermittently alternating with the front Openings of the conveying cylinder communicating and connected with its other end to a conveyor pipe Swivel tube and with a near the end of the conveyor tube on the swivel tube side or in one section arranged outside the material feed container of the swivel tube in the relevant tube wall arranged closable cleaning opening.
  • Thick matter pumps of this type are primarily used for pumping of concrete and more or less viscous Sludges are used, which solidify after long periods of inactivity can. Therefore the pipelines of the Thick matter pump and the material feed container at the end of a conveying process can be emptied and cleaned.
  • the Delivery line which is usually on a placing boom in concrete pumps attached, either by sucking it back of the concrete contained in it in the material feed container through the thick matter pump itself or under pressure in the reverse direction with the help of an in the delivery line injected pressure medium, such as compressed air or water.
  • Pipelines are made using elastomeric sponge balls or cleaning body, either over the free end of the conveyor pipe sucked to the material feed container or via suitable pipe fittings (EP-A-0 022 251) in the opposite direction. Further it is known to be closable in the region of the swivel tube Cleaning openings in the pipe wall provide through which for cleaning purposes Access to the inside of the pipeline is possible (EP-A-171 796). Yet So far the problem of Emptying using the material in the material feed container remaining concrete.
  • the invention is based on the object the known concrete pumps of the initially mentioned kind of improving that the conveyor pipes and the material feed container with simple movements can be emptied and cleaned.

  • a preferred embodiment of the Invention provides that the sealing body as under the Exposure to a pressure medium, preferably compressed air or hydraulic fluid spreadable, and against the inner surface of the tube or ball can be pressed is.
  • the two-cylinder slurry pumps shown in the drawing are for use in stationary and mobile concrete pumps determined. They essentially exist from two delivery cylinders 10 with hydraulic in Push-pull driven delivery piston 12, a material feed container 14 and one with a swivel tube 16 engaging in the material feed container 14, with a reversing mechanism 18 actuable slide device 20.
  • the feed cylinder 10 are in the lower area via openings 22 to the rear wall 24 of the material feed container 14 connected, the openings 22 on the inside of the material feed container 14 through an eyeglass-shaped wear plate 26 are limited.
  • the swivel tube 16 lies with its one a wear ring 28 bearing end against the Wear plate 26 and is by the reversing mechanism 18 depending on the direction of movement the delivery piston 12 in the delivery cylinders 10 in front of the one or the other opening 22 is pivoted. In this way is when the delivery piston is moved back in the direction of arrow 30 12 Material from the material feed container 14 through the opening 22 in the direction of arrow 32 in the relevant feed cylinder 10 sucked in while over the other delivery piston 12 material in the direction arrows 34, 36, 38 through the swivel tube 16 into an outside of the material feed container 14 Delivery pipe 42 is transported.
  • the conveyor pipe 42 can on a delivery line, not shown of a concrete placing boom.
  • FIGS. 1 and 2 differ mainly in the shape of the swivel tube 16.
  • this is Swivel tube is essentially S-shaped. It is on its opposite the delivery cylinders End over a container-fixed, to its swivel axis coaxial rotary pipe connection 43 with the delivery pipe 42 connected, and engages on the other side with one designed as a drive shaft axle shaft 45 by a Pivot bearing 47 of the material feed container 14 therethrough.
  • the stub of the axle shaft projecting outwards 45 is rotationally fixed with a reversing lever 46 of the reversing mechanism 18 connected up at his facing end two facing opposite sides, bearings 48 designed as ball sockets for the connection of a piston-side ball head 50 of the two drive cylinders 52 of the reversing mechanism 18 has.
  • the drive cylinders are on the cylinder side 52 with a further ball head 54 in one Supporting cylinder-fixed bearing designed as a ball socket 56 stored.
  • Fig. 2 Embodiment provided a C-shaped pivot tube 16, that from above into the material feed container 14 engages.
  • the swivel tube 16 is over a Flange 40 with the extension tube Conveyor tube 42 connected, which in turn via a Pipe rotary connection, not shown, to a delivery line a concrete placing boom is connected.
  • the flange 40 is connected by means of two clamping screws 44 the reversing lever 46 of the reversing mechanism 18 releasably connected, the opposite at its lower end two Side-facing ball pans Bearings 48 for the connection of a piston side Ball head 50 of the two drive cylinders 52 of the reversing mechanism 18.
  • On the cylinder side are the drive cylinders 52 with another Ball head 54 in a conveyor cylinder fixed, as Ball socket trained bearing 56 stored.
  • the Drive cylinders 52 can be pressurized with pressure oil on one side and contain a ball head 50 Plunger 60.
  • the pipelines the thick matter pump and the material feed container are emptied and be cleaned.
  • the pipelines the thick matter pump and the material feed container are emptied and be cleaned.
