Definitions

  • ABSTRACT A compact concrete preparing unlt havmg a frame which carries, besides a mixer and usual equipment for supplying cement, aggregates etc. to said mixer, an overhead [54] COMPACT UNIT FOR PREPARING CONCRETE runway rail for a travelling hoisting winch with a concrete 3Claims, 1 Drawing Fig. bucket to receive a charge of concrete from said mixer for transporting to a casting site adjacent a rail system, to which Cl 5: the runway rail of the compact unit may be connected after I Field 0 Search 259/1 54 having been vertically adjusted to the level ofsaid rail system.
  • This invention relates to a compact unit for preparing concrete, particularly for cast concrete element factories, with a frame, in which there is mounted a concrete mixer as well as apparatuses for the supply of proportioned quantities of aggregates, cement, water and possibly steam to the mixer.
  • Such compact units have, during the last few years, become widely used both on building sites and in factories for the manufacture of cast concrete elements and other concrete goods. This is due to the fact that it is possible to supply the complete units ready for use with all requisite auxiliary equipment, for instance, a so-called star doser and a pushbutton operated, fully or partly automatic control mechanism. Further, it is possible to move such compact units from place to place without any comprehensive dismantling.
  • a similar mode of transport of the mass is less suitable in cast concrete element factories, because the method of transport for this use is too time consuming and requires too much manual operation.
  • the transporting of the freshly mixed concrete to the various working sites by means of special vehicles has been dropped and preference has been given to automatically controlled transport units, e.g. those with conveyor belts or conveyor buckets.
  • Such transport units are, in practice usually supplied by manufacturers other than those who have specialized in the construction of the compact units proper, and during the installation there consequently often arise considerable difficulties in coordinating the two parts of the complete unit and in particular with respect of the control mechanisms of the individual parts.
  • the compact unit according to the invention is characterized in that its frame further carries an overhead height-adjustable runway rail for a travelling hoisting winch with a concrete bucket which when lowered, with the hoisting winch stationary in a predetermined position on the runway rail, is guided down into a filling position below the discharge aperture of the mixer and, subsequent to filling, is hoisted free of the guiding means and then together with the hoisting winch, is transferred to a rail system connected to the runway rail, to be transported to the casting site.
  • the frame comprises a pair of guide rails for the concrete bucket, arranged to catch the concrete bucket during its lowering with the hoisting winch stationary in the saidpredetermined position, and each having a substantially vertical main part which, via a bend at the bottom, passes into a horizontal or slightly inclined part directed towards the mixer.
  • These guide rails which may expediently engage with associated guide rollers at diametrically opposed points of the concrete bucket, ensure a very accurate guiding of the movements of this bucket into and out of the filling position. Consequently, no need exists for manual operation when the returning empty bucket is to be brought into the filling position, or the filled bucket is to be transported from this position to the place of delivery.
  • 1 designates a so-called star doser with a scraper unit 2 for bringing the aggregates 3 from the storing spaces of the unit into the weighing bucket 4 of the doser.
  • the bucket 4 is movable from its lower position (shown in fully drawn lines) along an inclined guide 5 to an upper position (shown in dotted lines) in which its contents can be emptied into the mixer 6 of the compact unit.
  • Cement and water may be added from an overhead feeder 18 and, when desired, other components, including steam for heating the mass, may be supplied to the mixer 6.
  • the difierent parts of the unit are carried by a transportable frame 7 with an upper or overhead runway rail 8 for a hoisting winch 9 which has travelling and hoisting control means, not shown in greater detail, and in which a concrete bucket 10 is suspended.
  • This bucket is shown in full lines in its filling position below the discharge aperture of the mixer 6, and in dotand-dash lines in its lowermost position and once again in dotand-dash lines in the uppermost position and labeled 10.
  • the concrete bucket may be of a construction known per se, e.g. with bottom flaps which are kept closed by the pull of the suspension cable of the bucket.
  • the hoisting winch 9 is shown in the drawing in its terminal position on the runway rail 8 nearest to the mixer 6.
  • the hoisting winch arrives at this. position with the empty concrete bucket 10 hoisted up to the maximum.
  • a pair of diametrically mounted guide rollers 19 are caught by a pair of associated guide rails 11, which force the bucket to be lowered vertically, and which at the bottom, via bent parts, pass into essentially horizontal rail parts 12, which extend to a point below the mixer 6.
  • the movement of the bucket 10 in the rail parts 12 can be effected by means of a jack 13, which is brought into and out of engagement with the bucket, but the bucket can also be moved into and away from its filling position by other means, e.g. by a carriage or trolley running on a horizontal path and on which the bucket is deposited by means of the hoisting winch 9.
  • the bucket 10 When the bucket 10 has been filled with a change from the mixer 6, it is hoisted-up to its maximum height so as to come clear of the uppermost end of the guide rails 11. Subsequent to this, the bucket shall be brought to a desired delivery position, e.g. above a silo 15 or 16 at a selected working station in a cast concrete element factory.
  • the runway rail 8 is connected to a rail system 17 leading to the different working stations of the concrete element factory.
  • the height level of such rail system may vary from factory to factory, and for this reason the runway rail 8 is vertically adjustable in the framework 7.
  • the concrete bucket 10 can be automatically transported back to the filling position.
  • a compact unit for preparing concrete, in particular for cast concrete element factories comprising a frame, a concrete mixer mounted in said frame together with apparatuses to supply proportioned quantities of aggregates, cement, water and possibly steam to said mixer, an overhead height-adjustable runway rail carried by said frame, a hoisting winch mounted for movement along said runway rail between a predetermined position adjacent said mixer and a free end of the rail remote from the mixer, a concrete bucket suspended from said hoisting winch, and means for guiding said concrete bucket to and away from a filling position below a discharge aperture of said mixer when said hoisting winch is in said predetermined position, said guiding means being disengaged from said bucket in its raised position so as to allow said hoisting winch with said bucket to travel from said predetennined position past said free end of the runway rail.
  • said bucket guiding means comprise a pair of guide rails arranged to catch said concrete bucket during its lowering with said hoisting winch in said predetermined position, each of said guide rails having an essentially vertical main part which, via a bend at the bottom, merges into a horizontal or slightly inclined part directed towards said mixer.
