Definitions

  • An invention relates to the method according to claim 1 for making concrete in a mixing bowl and for transporting it by using same mixing bowl to casting station, which is generally a casting mould or a plane-like structure.
  • the charging of the mixer is carried out mechanically at least concerning sand and water charging, the amounts of which are adjustable, too and the concrete mixing is carried in the mixer straight to the casting place.
  • FIG 1 is an embodiment, where a self-moving excavator 1 is as work machine. It is equipped with a grab-like bucket 5 having two parts and a water tank 3 has been formed in one of its booms. To the grab bucket 5 has been coupled a mixer 4. The excavator can take and transport said mixer to desired station. The mixer 4 has been partly filled with sand which has been loaded by the grab bucket of the excavator. The excavator lays the mixer 4 on the ground and can take sand with its grab bucket as far as the hoses 9,10 permit which are coupling the mixer to the hydraulic system of the excavator.
  • the boom 2 of the machine has a flexible support 14 for the hoses.
  • the grab bucket 5 has such a form that by means of it a known amount of sand can be charged repeatedly for ex. using the maximum load of the grab bucket.
  • the boom 2 has a water tank 3 for supplying water to the mixing bowl 4. There is many possibilities for adjusting the water amount. With water valve can be used a time relay which adjusts the water flow time. Cement can be charged in the mixing bowl by sacks. Cement can be loaded by means of the bucket 5, too.
  • FIG 2 is formerly known concrete mixer 4, which has an embodiment of quick locking needed according to the invented method.
  • the upper part of the mixer has a beam 6 on which arms 7 have been mounted turnable around joints.
  • the hydraulic cylinder 8 turns the arms.
  • pressure is lead to the cylinder 8 as presented in figure 2 the opening and closing of the locking means 7 are depending on that which one of the hoses 9 or 10 is used as supply line and which one is used as return line.
  • the mixing bowl 4 can thus be transported carried on by the grab bucket 5.
  • the mixing bowl has a discharging opening (not shown) in the bottom, through which the concrete mixing can be adjustable discharged to casting moulds.
  • figure 3 is a front view of the work machine 1.
  • the middle part of the grab 5 has a shoulder behind which the arms 7 are locking and preventing the bowl to drop from the bucket.
  • the excavator 1 is loading sand in the mixer 4.
  • the mixer blades are rotating continuous.
  • the pressure hoses are so long that the excavator can take sand from distance of several meters to the mixer.
  • the sand amount can be adjusted also by weighing when the height of actual pressure in some of the boom cylinders shows the weight when the bucket is lifted up. Also gauges can be used which are measuring the load of the boom or its parts when the bucket contains sand.
  • the measuring of cement amount by weighing is carried out in the same way.
  • Water charging can be carried out by weighing, too, the flow meter can be used or by means of measuring time when water is running to the mixer.

Claims (5)

  1. Un procédé de fabrication et de transport de béton vers un site de coulage, conformément auquel un récipient (4) équipé d'un élément mélangeur est utilisé pour mélanger le béton, et un engin de travail (1) ou un véhicule est utilisé pour transporter ledit récipient, et le grappin (5) ou le godet dudit engin ou véhicule est utilisé pour doser le sable dans ledit récipient de mélange (4), caractérisé par le fait que le béton est transporté vers le site de coulage dans le récipient de mélange (4) posé sur le grappin (5) ou le godet de l'engin de travaille et par le fait que, pendant le dosage, malaxage et transport, ledit récipient est directement relié à l'engin de travail (1) au moyen des flexibles hydrauliques sous pression (9, 10).
  2. Un procédé conforme à la revendication 1, caractérisé par le fait que, pendant ledit dosage de sable dans le récipient de mélange (4), ledit récipient est placé sur le sol et relié à l'engin de travail (1) au moyen desdits flexibles hydrauliques (9, 10).
  3. Un procédé conforme à la revendication 1 ou 2, caractérisé par le fait que la flèche de l'engin de travail est munie d'un réservoir à eau (3) ainsi que d'un dispositif régulant le dosage d'eau.
  4. Un procédé conforme à l'une des revendications 1 à 3, caractérisé par le fait que le récipient de mélange (4) est relié au grappin (5) ou au godet au moyen d'éléments de blocage (7), dont le fonctionnement se contrôle depuis la cabine de l'engin de travail.
  5. Un procédé conforme à la revendication 4, caractérisé par le fait que l'ouverture et la fermeture des éléments de blocage (7) se fait par rapport au débit de liquide sous pression faisant tourner le malaxeur (12).
