Definitions

  • the present invention relates to a transportable installation for mixing concrete, provided with a chassis consisting of at least two portions, some components of the proper installation being accomodated in said chassis portions.
  • Such an installation is known from Dutch patent application 76.04126.
  • Said known installation is embodied in the shape of a trailer which can be brought on the building site with a tractor.
  • the trailer consists of a two-part chassis, said chassis portions being pivotally interconnected, in which the portions are aligned in the transport position and in the operative position the one front portion can be located at right angles or almost at right angles to the other rear portion and then both portions together can serve as a mixing installation.
  • a tractor is needed to transport the installation.
  • one or more sets of wheels should be mounted beneath the rear chassis portion and the installation is in fact restricted to transport by road.
  • both portions of the chassis should be fixedly and rigidly interconnected, to avoid deformation of the chassis and/or the installation and moreover the bottom clearance between the bottom of the chassis and the road is restricted.
  • a provision is missing in the chassis portions for the storage and the supply of cement to the mixing installation, so that the known installation cannot be considered as a transportable complete concrete supply station.
  • the object of the present invention is to remove the objections of said known installation.
  • the chassis comprises paralle3Epiped-shaped frames which are transportable independently from each other and interconnectable at the building site, the external shape and size of said frames being equal to those of a container for freight traffic and in that all necessary components of a concrete supply station are accomodated in the frames.
  • the frames with their shape and sizes satisfy the international shape and sizes determined for containers, the frames with the components of the installation can be transported independently from each other by container truck, train, ship or even with a container plane, with which it is not necessary to take precautions to fix the frames with respect to each other. Thereby the costs for transport can be held very low.
  • the frames, which are transported in horizontal condition can be erected by means of a crane and can be easily interconnected, after which after effecting the connections between the components the installation is ready for operation.
  • a digging machine with dragging bucket is disposed in the first frame, whereas in the operative condition of the installation at the free side of the first frame a storage for the additions sand and gravel is formed on the site, on which the installation is placed, and in the second frame a cement conveyor coupled with the cement dosage hopper is mounted and the installation is provided with a third frame, in which a cement container is accomodated, which can be coupled with the cement conveyor.
  • the necessary materials can be brought via a dosage device in the weighing box by means of the digging machine disposed in the first frame.
  • the cement container disposed in the third frame can be directly coupled with the cement dosage hopper on the mixing device by the cement conveyor, so that the supply of cement can take place automatically.
  • the cement hopper is provided with a cement conveyor coupled therewith the cement can also be supplied to the mixing device by arranging a platform at the supply end of the conveyor, said platform comprising a grid at the upper side, on which grid cement bags can be opened.
  • cement bunker which is not accomodated in one of the chassis portions, is mounted on a non-displaceable, carrier tower built next to the installation said cement bunker must be connected to the cement dosage hopper with a cement conveyor which is neither accomodated in the installation.
  • the second and/or the third frame can be mounted at a higher level than the first frame. Thereby it is possible to drive a so-called truck mixer beneath the mixing device in the second frame and to fill it from the mixing device.
  • the transportable installation according to the invention for mixing concrete is, according to fig. 1 and 2, accomodated in two frames 1 and 2, the sizes of which correspond to those of containers for freight traffic.
  • a digging machine 3 with a drag bucket 4 dosage devices 5, a weighing box 6, a portion of a weighing box conveyor 7 and an operation centre 8.
  • Said operation centre 8 may be mounted also completely or partially in the frame 2.
  • a vehicle 13 with a tank for the produced concrete is driven beneath the mixing device 12 in the frame 2, with which the concrete can be brought to the discharging point.
  • the frames 1 and 2 in which the above components of the installation are accomodated, are brought to their destination in horizontal position on a container truck, by container ship, or by container train and/or with a container plane. There the frames 1 and 2 are unloaded with a hoisting crane, subsequently erected in vertical position according to fig. 1 and then interconnected by means of bolts and nuts 14 or other mounting means.
  • the two parts of the weighing box conveyor 7 are interconnected and the cement conveyor 10 with its platform 11, which can be accomodated in the frame 1 during transport, is connected to the cement dosage hopper 9 and the platform 11 is mounted.
  • a storage for sand and gravel (rough and fine) is formed, in which on the ground in front of the installation one or more bulk heads 15 and a partition 16 with shores 17 have been arranged, dividing the ground in two or more compartments 18, 19 and 20, in which said materials can be stored.
  • the installation built-in in the frames 1 and 2 is completely fitted with electrical wiring and with connections for current and for water. After the connections to the electricity network and the waterworks are effected, the transportable concrete supply station is ready for operation.
  • the weighing box 6 When the weighing box 6 is filled with the correct quantities of material, it is pulled upwardly along the weighing box conveyor 7 with an engine or a winch or in an other way toward the mixing device 12 and the contents of the weighing box are poured into the mixing device.
  • Bags of cement can be opened on the platform 11 and emptied there, after which the cement is brought into the mixing device 12 by means of the conveyor 10 and the cement dosage hopper 9, in which mixing device after supply of water concrete can be produced, which can be brought to the poaring location by means of the vehicle 13.
  • the operation of the installation according to the invention can be completely automatic according to a predetermined program.
  • the various functions and processes of the installation can, however, also be started and stopped in the operation centre 8.
  • the installation according to the invention for mixing concrete according to the fig. 4, 5 and 6, is just like the embodiment according to the fig. 1 and 2, provided with frames 1 and 2, in which in the frame 1 the digging machine 3 with drag bucket 4, the dosage devices 5, the weighing box 6, the first part of the weighing box conveyor 7 and in the frame 2 the second part of the weighing box conveyor 7, the operation centre 8, the cement dosage hopper 9 with the cement conveyor 10 and the mixing device 12 can be accomodated.
  • the storage compartments 18, 19 and 20 are also formed in the same way, whereas the frames 1 and 2 are interconnected in the same way and the installation is coupled with the waterworks and the electrically network.
  • a third frame 21 is mounted next to the second frame 2, said third frame being connected to the frame 2 by means of bars or beams or other profile memebers 22.
  • a cement bunker or cement container 23 is mounted and the cement conveyor 10 is connected to the lower end of the cement container 23 by means of its supply end. In this way the supply of cement to the mixing device 12 can also take place automatically.
  • a third embodiment of the installation according to the invention is shown, which is especially meant for filling so-called truck mixers.
  • This installation is provided with a first frame 1, constructed and arranged in the same way as in the embodiment according to fig. 1 through 6.
  • a digging machine 3 with drag bucket In the frame 1 are accomodated a digging machine 3 with drag bucket, dosage devices 5, a weighing box 6, a part of a weighing box conveyor 7 and an operation centre 8.
  • a second frame 24 has been mounted at a higher level and for that reason is provided with legs 25, whereas the frame 24 is connected to the frame 1 by means of bars, beams or other connecting members 26.
