    专利说明:

    [0001] The present invention relates to a pump for concrete, with a support structure that can be inserted on a chassis of a truck chassis, for receiving functional units, which form a support device and a distributor lance, the functional unit that forms the dispensing lance has a rotating head mounted on a lance pedestal, which is fixed to the support structure, rotatable around a vertical axis, and the lance pedestal comprises a tank that engages with the structure of support, and is equipped as a rotating bearing for the rotating head and the functional units that form the support device comprise, in each case, a support leg, mounted on a bearing in a rotatable and/or extensible manner, being that said bearing is fixed to the support structure.
    [0002] Concrete pumps of this type are known (DE-100 32 622 A1). The support structure has the task of introducing the weight and moment of loading of the distributor boom into the underlying surface through the support device. Normally the support device comprises four support legs articulated pivotally on the support structure, which can be supported by hydraulic cylinders on the underlying surface. The interface between the distributor lance and the support device is formed by the tank as the central component of the lance pedestal, on which the rotating head of the distributor lance is mounted through a rotating bearing and a drive mechanism. The tank is a highly loaded component that needs to receive loads from the spreader boom and transmit them to the support legs. Normally, the tank is made in a cylindrical or polygonal way around the rotation axis of the dispensing boom. All known tanks have in common the property that the cross section does not change over their height. It has been shown that this configuration, with an unalterable cross section over height, is not properly constructed for loading.
    [0003] Starting from this fact, the invention is based on the task of configuring the known mobile pump for concrete in a lighter way in its support structure, more economical in space and, nevertheless, suitable for loading.
    [0004] To solve this task, the characteristics indicated in the present invention are proposed. Advantageous configurations and improvements of the invention are evident from the embodiments.
    [0005] The solution according to the invention starts from the idea that it presents a light construction and, nevertheless, suitable for loading, when the tank narrows in cross section from top to bottom. Consequently, according to the invention it is proposed that the tank, with its tank wall, which narrows from top to bottom in the manner of a truncated cone or truncated pyramid, engages the support structure and is rigidly inserted therein. .
    [0006] The construction according to the invention saves the use of unnecessary material and, with this, reduces the weight of the component and thus also the weight of the machine. The shape, which narrows from top to bottom, creates space between the supporting construction and the jib pedestal, in which installations, particularly in a supporting structure with four swivel legs, can be installed space-saving. Advantageously, in the construction space obtained, telescopic cylinders for telescopic swivel legs can be installed, which hitherto needed to be installed in a complex, expensive and difficult to access way, inside the telescopic legs. This gain in space is especially important in large machines.
    [0007] A preferred configuration of the invention provides that the tank has a vertical passage opening for the passage of a concrete conveyor line.
    [0008] Another advantageous configuration of the invention provides that support arms belonging to the support structure are welded to the tank, which have support eyes arranged at a distance from the wall of the tank, in which one of the legs is arranged in each case. support, swiveling around a vertical axis.
    [0009] Another reduction in material use can be obtained by the fact that the tank wall forms a truncated surface obliquely rising in the running direction of the concrete pump. In this case, the tank can be supported with its truncated surface oblique on a support frame of the support structure, obliquely ascending in the direction of travel.
    [00010] In the following, the invention is explained in more detail by means of an example of embodiment schematically represented in the drawing. Show:
    [00011] Figures 1a and b a side view and a top view of an automatic concrete pump, with a distributor lance and an extender device;
    [00012] Figures 2 and 3, in each case, a diagrammatic representation of the support structure of the automatic concrete pump according to Figures 1a and b, with a support leg of the support device and the tank arranged on the boom pedestal of the support structure.
    [00013] The automatic concrete pump shown in Figures 1a and b consists substantially of a multi-axle chassis 10, with two front axles 11 and three rear axles 12, with an operator's cabin 13, a distributor boom 15, mounted on rotary mode by means of a rotating head about a vertical axis 19 on a jib pedestal 14 close to the front axle, with a pump arrangement mounted on the chassis 10 at a distance from the jib pedestal, as well as with a support structure 17 inserted onto the chassis 10 for a support device 18. The support device 18 comprises two front support legs 20 and two rear support legs 22, 22', which are pivotally joined to the support structure 17. support are retracted in the transport position and aligned parallel to the longitudinal axis of the vehicle 24, while in the support position they protrude forwards or backwards beyond the chassis and with their foot parts 26, 28 and are supported on the underlying surface 30. The front support legs 20 are displaceable, in this case, around their vertical swivel axes 32 and the rear support legs 22, 22' are displaceable around their vertical swivel axes 34 between the transport position and the support position under the action of, in each case, an extension cylinder 36, in relation to the support structure. In an example of a modified modality, it is in principle also possible that the front and rear support legs 20, 22, 22' adjacent to each other are moved by means of a common drive. Additionally, the front support legs 20 are formed as telescopic arms. As can be seen particularly from Figure 1b, they comprise, in each case, an arm box, displaceable in each case around a swivel axis 32 vertical with respect to the support structure 17, and a telescopic part. 40 consists of three telescopic tubes.
    [00014] The central component of the lance pedestal 14 is the tank 42, which forms the interface between the dispensing lance 15 and the support device 18. The rotating head 19 of the dispensing lance is inserted from above onto the tank 42 and mounted therein swiveling around a vertical axis. The drive takes place through a toothed ring 44, rigidly arranged on the rotating head 19 and rotatably mounted on the tank through a roller bearing, with the help of two hydraulic or electric drive motors 44, which engage with a drive pinion 57 in the toothed ring 44. The drive motors 45 are arranged in splints 46 of the boom pedestal, secured to the tank. The tank has a vertical passage opening 32 for the passage of a concrete conveyor line not shown. As the tank forms a vertical bearing for the distributor boom 15, it receives the load over its height. The load is maximum at the upper end close to the rotary bearing 48 and decreases in a downward direction.
    [00015] The shape of the tank 42 is adapted to the load course in that its cross section narrows conically from top to bottom. This construction saves unnecessary material usage and lowers the component weight and thus also the machine weight. The conical shape also creates space between the support legs 20 and the jib pedestal 24 for mounting the necessary installations. In particular, telescopic cylinders 62 for the extendable support legs 20 can be installed in the construction space obtained, which until now could only be installed in a difficultly accessible way inside the telescopic legs.
    [00016] As can be seen from Figures 2 and 3, the support arms 50 belonging to the support structure 17 are also welded to the tank, which have support eyes 52, 54 arranged at a distance from the wall of the tank, in which, in each case, one of the support legs 20, 22, 22' is pivotally supported about a vertical axis.
    [00017] As can be seen in Figures 2 and 3, another particularity of the invention consists in the fact that the tank wall 56, which forms a truncated cone, forms a truncated surface 58 open downwards, obliquely ascending in the running direction of the concrete pump, which is supported on a support frame 60 of the support structure 17 obliquely ascending in the direction of travel. This results in additional weight savings.
    [00018] In summary, the following can be registered: the invention relates to a mobile pump for concrete, with a support structure 17, which can be inserted onto a vehicle frame 10 of a truck chassis, for receiving functional units, which form a support device 18 and a dispensing lance 15, the functional unit forming the dispensing lance 15 having a swivel head 19, rotatably mounted around a vertical axis on a fixed lance pedestal 14 in the support structure, and the lance pedestal 14 comprises a tank 42 engaged in the support structure 17 and equipped with a rotary bearing 48 for the rotary head 19 and the functional units forming the support device 18 in each In this case, a support leg 20, 22, 22', rotatably and/or extendably mounted on a bearing 52, 54, fixed to the support structure. A particularity of the invention consists in the fact that the tank 42, with a tank wall 56, which narrows from top to bottom in cross section in the manner of a truncated cone or truncated pyramid, engages the support structure 17 and is inserted rigidly, preferably welded, in it.
