  • the object of the invention is to improve the known mobile thick matter pump in such a way that for a given pump speed the
  • the solution according to the invention is based on the idea that the change gearbox has at least two gear ratios, the selection of which allows different maximum engine speeds to be set via the speed limiting device. It is particularly advantageous if two selected gear ratios with direct gear ratio and with ms fast gear ratio (overdrive) are each assigned a different maximum engine speed depending on the gear ratio. If in this case, with direct gear ratio switched on, the low-cost nominal engine speed as If the maximum engine speed is set, the maximum engine speed is expediently reduced when switching to the translation into the fast and constant ratio in the transfer case so that the maximum permissible pump speed is not exceeded. With a lower engine speed and therefore lower noise and lower fuel consumption, you get the opportunity to fully exploit the optimal pumping frequency. This is the case when the maximum engine speeds assigned to the various gear ratios are selected to be essentially proportional to their gear ratio.
  • the maximum engine speeds can be set using either mechanical or electronic means.
  • the speed limitation device expediently an adjustable mechanical end stop on an adjusting mechanism for controlling the fuel supply to the vehicle engine
  • the speed limiting device can comprise a microprocessor circuit for limiting the engine speed in accordance with the gear ratio step that is currently switched on.
  • a particularly simple handling is ensured if a sensor is provided for controlling the speed limiting device, which sensor responds to the shift position of the change gear.
  • a further improvement in this regard is achieved if a switching device, which responds to remote control signals from a pump remote control, is provided for remote switching of the change gear and for corresponding control of the speed limiting device.
  • Switchover of the gear ratios and the associated maximum engine speeds can be provided, which responds either to falling below or exceeding a predetermined pump pressure or a predetermined minimum speed or a measurement variable derived therefrom.
  • Figure 1 is a side view of a mobile concrete pump with concrete placing boom in the folded state.
  • FIG. 2 shows a diagram of the drive and pump drive of the mobile concrete pump according to FIG. 1.
  • the mobile concrete pump shown in FIG. 1 has a chassis 10, a pivot bracket 16 arranged in the vicinity of the front axle 12 and the driver's cab 14 of the chassis 10, a placing boom 20 rotatable on the pivot bracket 16 about a vertical axis 18 through 360 °, one over a Material feed container 22 to which concrete can be applied, hydraulically driven concrete pump 24 and a delivery line 28 connected to the concrete pump 24 via a pipe switch 26.
  • the five mast arms 1, 2, 3, 4 and 5 of the placing boom 20 are connected to the pivot joint A on the swivel joint A and at the articulated joints B, C, D and E.
  • the mast arms 1 to 5 are folded in and out hydraulically around the joints A to E by means of double-acting hydraulic cylinders 30 which, with their free cylinder-side and rod-side ends, are articulated on cantilevers or folding brackets of the mast arms 1 to 5 and the pivot bracket 16 .

Abstract

L'invention concerne une pompe à liquides épais mobile, comprenant un mécanisme d'entraînement constitué d'un moteur (40) de véhicule et d'une boîte de vitesses (42), au moins une pompe hydraulique qui peut être raccordée à un arbre de sortie (46) de la boîte de vitesses, éventuellement par l'intermédiaire d'une boîte de vitesses (48) intermédiaire, et qui sert à entraîner la pompe (24) à liquides épais, ainsi qu'un dispositif limitateur de vitesse qui permet de régler une vitesse maximale lorsque le moteur fait fonctionner la pompe. Pour permettre d'obtenir, de façon sélective, un fonctionnement optimal de la pompe avec de faibles émissions sonores, la boîte de vitesses possède au moins deux étages de transmission, dont l'enclenchement permet de régler différentes vitesses de rotation maximales pour le moteur par l'intermédiaire du dispositif (70) de limitation de vitesse.
