Definitions

  • ABSTRACT A concrete delivery unit for the mixing and delivery of UOSI l i
  • a concrete comprising a rotatable drum having a filler 2 Int- Cl. i i open ng and an outlet open ng a feed hopper at- [58] Field of Search 259/177 R, 177 A, 175,
  • This invention relates to a concrete delivery unit for the mixing and for the controlled, continuous and intermittent delivery of mixed concrete.
  • the object of the present invention is to solve the problem of bringing to a building site semi-dry concrete with the water content necessary for concreting, or of cutting down the waiting and discharge times of mobile mixers with ready-mixed concrete at the building site, taking into accountthe limited space generally available at such sites.
  • a concrete delivery unit for the mixing and delivery of mixed concrete, comprising a rotatable drum having a filler opening and an outlet opening, a feed hopper arranged at the filler opening, and a controllable closing device arranged at the outlet opening.
  • the concrete brought in mobile mixers or trough-shaped trucks is discharged into the low placed, spacious feed hopper located in front of the drum. From there, the concrete passes into the adjoining rotating drum which is capable of taking the entire volume of the transported concrete.
  • a watering device water is added to the semi-dry transported concrete and mixed thoroughly as required.
  • a worm located inside the drum is effective both for the mixing as well as for movement of the concrete towards the outlet opening, which is located higher up than the feed hopper so that a crane bucket or the filler hopper of a concrete pump can be brought directly beneath the outlet opening and filled.
  • a cover which can be moved forward and back ward is placed in front of the outlet opening. With this the flow of the concrete is regulated according to the different intake conditions at the building site.
  • the speed of rotation of the drum is preferably adjustable.
  • the waiting or unloading times of mobile mixers which transport ready-mixed concrete can be substantially reduced by delivering the ready-mixed concrete into the delivery unit.
  • the building site is quickly supplied with concrete and the mobile mixers can travel more frequently, so that the profitability of their use is improved.
  • the feed hopper has at least the width of the superstructure of a lorry and the drum is so arranged as to be capable of taking the quantity delivered from the lorry.
  • the concrete delivery units and separate concrete discharge appliances each require at the building sites a considerable space. Additional difficulties arise if the concrete discharge pipe is secured to a distribution pole which is mounted together with the concrete discharge appliance on a common chassis. Extending arms of this type are needed with multi-storey buildings so as to take the pipe-line for the concrete to be transported to the pouring place.
  • the erection of the distribution pole at the building site is predetermined by the field of work and its working distance, with the delivery unit with its outlet opening projecting over the intake hopper of the discharge appliance, e.g. the concrete pump.
  • the delivery unit for its part must be set up in such a way that transporting troughs or mobile mixers can deliver their contents to it. These conditions can usually, however, only be satisfied with difficulty, and in many cases not at all.
  • a folding extension which can be raised, lowered and rotated, having a concrete feed line connected to the concrete discharge appliance is arranged.
  • a rotatable chute can be arranged in front of the outlet opening of the concrete delivery unit, so that by swivelling the chute out sideways concrete can also be taken out for smaller building operations at other sites, without the concrete discharge appliance needing to be disconnected from the concrete feed line.
  • Adjustable supports may be provided on the frame to reduce the load on the wheels during operation.
  • FIG. 1 is a side view of a concrete delivery unit according to the invention
  • FIG. 2 is a plan view of the concrete delivery unit
  • FIG. 3 is a partial section through the ring secured to the frame, with the feed hopper, the elastic cone and the unloading partial cone;
  • FIG. 4 is a side view of a unit composed of a delivery unit and a concrete pump
  • FIG. 5 is a side view of a unit composed of a delivery unit, a pump and a distributing pole
  • FIG. 6 is a front end elevation of the drum and a portion of the 'mounting for same.
  • FIG. 7 is a transverse sectional view on the line 7-7 of FIG. 6.
  • a frame 1 has an undercarriage 2 and a removable trailer shaft 3.
  • a rotating drum 4 provided with a peripheral running ring 4 and a circular ring gear 5 which is fixed to the drum and is driven by a pinion 5a powered by a hydraulic motor 6 carried by a frame 6a.
  • Beneath the motor 6 is located a driving motor with an adjustable hydraulic pressure generator 7.
  • Another ring 5b supports the circular ring gear 5 and is mounted in two journals 9 and 9' on a supporting stand 8.
  • a mount 10 has a hydraulic sliding cylinder 11 to which is operatively connected a closing disc 12 for closing the drum outlet opening 12', which is located above the feed hopper 16.
  • a water supplying device 13 which includes a pipe 14 leading into the drum 4.
  • a ring 15 which has secured to it a feed hopper 16 and an elastic cone 17 which in the filler zone is covered by a dicharging partial cone 18.
  • a drum 102 of the delivery unit is arranged lengthwise in the frame 103 of a low-bed trailer.
  • the unit includes an intake hopper 104 for the introduction of semi-dry or readymixed concrete, which, if required, is mixed with additional water inside the drum 102 by rotation of the drum and is moved on to an outlet opening 108 by the rotation of a worm 105 arranged in the drum, the quantity delivered being pre-determined by setting a closing device 106, arranged so as to slide in an axial direction, and the speed of rotation of the drum.
  • the intake hopper 104 is placed at such a height that a vehicle delivering the concrete to the hopper can discharge this directly.
  • the concrete feed device comprises a concrete pump 107, arranged beneath the outlet opening 108. It extends, with cylinders 109, of which only one is shown and in which the pistons for drawing in and ejecting the concrete are located, as well as with housing 110, into the frame 103 beneath the drum 102 or into the space between the latter and frame 103.
  • the frame 103 forms part of a low-bed trailer
  • a concrete feed pipe 112 is arranged below the upper frame section of frame 103.
  • the driving unit 107 of the concrete pump is a hydraulic motor.
  • a chute 114 which projects over the concrete pump 107 and can be swung out sideways for unloading small quantities of concrete.
  • FIG. 5 shows the entire delivery unit before extending the folded extension 117.
  • Rotating column 116 has, co-axially with the axis of rotation of the folding extension 1 17, a section of pipe 1 19 which is connected at its lower end to the concrete pump 107 through a swivel joint 120 and an elbow 121, and at its upper end to the concrete feed line 118.
  • hydraulically extendable supports 126 and 127 are arranged near the front and rear ends of frame 103 and carry the entire weight in the extended condition.
  • Apparatus for mixing and delivering concrete comprising a. a mobile frame,
  • a rotatable drum on said frame with its axis at all times oblique to the lengthwise direction of said frame and having vertically spaced inlet and outlet openings at the rear and front ends respectively with the rear end and outlet opening uppermost,
