Definitions

  • the invention relates to a thick matter pump with a material feed container, two hydraulically driven conveying cylinders opening with their front openings into the interior of the material feed container, an engaging in the material feed container, with one end alternating in cycles with the front openings of the feed cylinders and communicating with its other end a feed pipe connected swivel pipe and with a closable cleaning opening arranged in the vicinity of the end of the feed pipe on the swivel pipe side or in a section of the swivel pipe arranged outside the material feed container in the relevant pipe wall.
  • Thick matter pumps of this type are mainly used for pumping concrete and more or less viscous sludge, which can solidify after a long standstill. Therefore, the pipes of the thick matter pump and the material feed container have to be emptied and cleaned at the end of a conveying process.
  • the delivery line which is usually attached to a placing boom in concrete pumps, can either be sucked back into the material feed container by the thick matter pump itself, or under pressure in the opposite direction with the help of a pressure medium, such as compressed air, which is pressed into the delivery line or water.
  • the pipelines are wiped out by means of elastomeric sponge balls or cleaning bodies, which are either sucked over the free end of the conveying pipe to the material feed container or pressed in the opposite direction using suitable pipeline fittings (EP-A-0 022 251). Furthermore, it is known to provide closable cleaning openings in the pipeline wall in the region of the swivel tube, through which access into the interior of the pipeline is possible for cleaning purposes. The problem of emptying using the residual concrete in the material feed container has not yet been satisfactorily solved.
  • the object of the invention is to improve the known concrete pumps of the type specified at the outset in such a way that the delivery pipes and the material feed container can be emptied and cleaned in a simple manner.
  • the front delivery cylinder openings opening into the material feed container are at least partially coverable or closable against air access from the material feed container to the vicinity of the container bottom, preferably by means of a slide.
  • the shut-off device can be designed, for example, as a gate valve, which is expediently arranged in the region of a connecting flange on the delivery pipe outside the material feed container.
  • the shut-off device can also be designed as a sealing body which can be pressed into the inside of the pipe against the conveyor pipe or swivel pipe, preferably deformable under the influence of pressure, which can be inserted into the delivery or swivel pipe from the cleaning cartridge and in this preferably by means of a limp, band-like or chain-like holding member is positionable.
  • a seat or support member for the sealing body which engages in the interior of the pipe, preferably from the cleaning opening, can be used independently of the holding member or in addition be provided.
  • a preferred embodiment of the invention provides that the sealing body is designed as a ball or balloon which can be expanded under the action of a pressure medium, preferably compressed air or pressure fluid, and can be pressed against the inner surface of the pipe.
  • the two-cylinder slurry pumps shown in the drawing are intended for use in stationary and mobile concrete pumps. They essentially consist of two delivery cylinders 10 with delivery pistons 12 driven hydraulically in push-pull, a material feed container 14 and a slide device 20 which engages with a swivel tube 16 into the material feed container 14 and can be actuated with a reversing mechanism 18.
  • the feed cylinders 10 are connected in the lower region via openings 22 to the rear wall 24 of the material feed container 14, the openings 22 on the inside of the material feed container 14 are limited by an eyeglass-shaped wear plate 26.
  • the swivel tube 16 abuts with its one end, which carries a wear ring 28, against the wear plate 26 and is swiveled in front of one or the other opening 22 by the reversing mechanism 18 depending on the direction of movement of the delivery pistons 12 in the delivery cylinders 10.
  • the delivery pipe 42 can be connected to a delivery line, not shown, of a concrete placing boom.
  • the exemplary embodiments shown in FIGS. 1 and 2 differ primarily in the shape of the swivel tube 16.
  • the swivel tube is essentially S-shaped. It is at its opposite the delivery cylinders Connected to the delivery pipe 42 via a tubular pipe joint 43, which is fixed to the container and coaxial with its pivot axis, and, on the other hand, engages with an axle shaft 45 designed as a drive shaft through a rotary bearing 47 of the material feed container 14.
  • the outwardly projecting stub shaft of the axle shaft 45 is rotatably connected to a reversing lever 46 of the reversing mechanism 18, which at its upward-facing end facing two opposite sides, designed as ball sockets 48 for the connection of a piston-side ball head 50 of the two drive cylinders 52 Reversing mechanism 18 has.
  • the drive cylinders 52 are supported with a further ball head 54 in a bearing point 56 which is fixed to the delivery cylinder and is designed as a ball socket.
  • a C-shaped swivel tube 16 is provided which engages in the material feed container 14 from above.
  • the swivel tube 16 is connected via a flange 40 to the delivery tube 42, which is designed as an extension tube and which in turn is connected to a delivery line of a concrete placing boom via an unillustrated tube rotary connection.
  • the flange 40 is releasably connected by means of two clamping screws 44 to the reversing lever 46 of the reversing mechanism 18, which has at its lower end two bearing points 48, which are designed as ball sockets, for the connection of one piston-side at its lower end Ball head 50 of the two drive cylinders 52 of the reversing mechanism 18.
  • the drive cylinders 52 are supported with a further ball head 54 in a bearing point 56 which is fixed to the delivery cylinder and is designed as a ball socket.
  • the drive cylinders 52 can be pressurized with pressure oil on one side and contain a plunger 60 that supports the ball head 50.
  • cleaning openings 80 are provided in the area of the tube walls of the swivel tube 16 (FIG. 2) and / or the delivery tube 42, which can be closed with a cover 82 and a coupling element 84.
  • an opening 72 On the underside of the material feed container 14 there is an opening 72 which can be closed with a swivel lid 70 and through which the material feed container 14 can be completely emptied.
  • the material feed container 14 can be emptied via the concrete pump.
  • the cleaning opening 80 on the swivel tube 16 is equipped with a pressure hose 122 and the path to the delivery tube 42 is blocked by the balloon 98.
  • slide 124 ensures that If only the lower area of the feed cylinder openings 22 is open towards the material feed container 14, the material feed container can be almost completely emptied using these measures. The remaining concrete then remaining can be removed via the opening 72.
  • the invention relates to a thick matter pump, in particular a concrete pump, with a material feed container 14, two conveying cylinders 10 opening with their end openings 22 into the interior of the material feed container 14, and one end intermittently engaging in the material feed container 14 alternately with the end openings 22 of the feed cylinder communicating and with its other end connected to a feed tube 42 and with a pivot tube 16 near the end of the feed tube 42 on the pivot tube side or in a section of the pivot tube 16 arranged outside the material feed container in the relevant tube wall Cleaning opening 80.
  • a transport pipe 122 can be connected to the cleaning opening 80, while the delivery pipe 42 or the swivel pipe 16 towards the free delivery pipe end by means of a shut-off element 98 is lockable.
